Diabetes mellitus is a metabolic disorder. Synthetic antidiabetics are the commonly used treatment options associated with complications. The objective of this study was to explore the antioxidative and antidiabetic potential of Euphorbia helioscopia whole plant ethanolic extract using in vitro and in vivo models. For that purpose, the antioxidative potential was explored by using 2,2‐diphenyl‐1‐picrylhydrazyl analysis. In vitro antidiabetic potential of the extract was evaluated using amylase inhibitory analysis. In vivo antidiabetic activity of the extract was assessed in diabetic rats using streptozotocin/nicotinamide (60 mg/kg/120 mg/kg) as an inducing agent. Metformin was used as standard. The results indicated the presence of significant quantities of phenolic 82.18 ± 1.28 mgg−1 gallic acid equivalent (GAE) and flavonoid 66.55±1.22 mgg−1 quercetin equivalent (QE) contents in the extract. Quantitation of phytoconstituents exhibited the presence of sinapic acid, myricetin, and quercetin using HPLC analysis. The extract inhibited α‐amylase by 84.71%, and an antiglycemic potential of 50.34% was assessed in the OGTT assay. Biochemical analysis demonstrated a reduction in urea, creatinine, cholesterol, low‐density lipoprotein, and alkaline phosphatase (p < 0.001) as compared to diabetic control rats at the dose of 500 mg/kg. An upregulation in the expressions of glucokinase, glucose transporter 4, peroxisome proliferator‐activated receptor γ, and insulin‐like growth factor was observed in treated rats in contrast to G6P expression, which was downregulated upon treatment. In conclusion, this study provided evidence of the antioxidative and antidiabetic potential of E. helioscopia whole plant ethanolic extract through in vitro and in vivo analysis and emphasized its promising role as a natural alternative.

On October 7, 2021, a magnitude 5.9 earthquake struck the Harnai (Baluchistan) region of Pakistan, causing several fatalities and injuries within the epicentral area. First-order tectonic deformation in this region is caused by the convergence of the Indian Plate with respect to the Eurasian Plate. The Katwaz Block hinders the motion of the Indian Plate, resulting in the formation of strike-slip faults. In this study, the P-wave first-motion polarity technique was used to determine the mainshock faulting style. Cyclic scanning of the polarity solutions was applied to determine the most suitable focal mechanism solution among the available solutions generated by the FOCMEC (focal mechanism) software. The nodal planes correspond to different faulting styles (i.e., thrust and strike-slip faulting). A nodal plane oriented in the NW-SE direction corresponded to a strike-slip mechanism, which was considered to be the fault plane. Tectonically, this earthquake was associated with the Harnai-Karahi strike-slip fault zone owing to the fault strike and direction of slip. The apparent stress drop, fault length, and moment magnitude of the Harnai earthquake were 35.4 bar, 6.1 km, and 5.9, respectively. A lower b-value for the Gutenberg-Richter law was observed prior to the earthquake. Higher α- than b-values (α > b) indicate that this earthquake was governed by large events as opposed to small-magnitude events. The Harnai sequence had a decay exponent close to unity, lasted for 145 days, and produced few aftershocks. The study will help the future hazard mitigation in the region. [ABSTRACT FROM AUTHOR]

The world population is severely affected by water scarcity, and it is an alarming issue that needs to be addressed urgently. Seawater desalination by solar‐driven evaporation is a promising technique to produce clean water. However, it is energy intensive and directs to a low water yield under natural sunlight. Therefore, the developments of new photothermal materials can reduce required energy for desired evaporation rates for efficient freshwater yield. Indeed, chitosan and polypyrrole‐based polymers are natural cationic copolymers, and their nanocomposites present well deal of interest for hydrogel structures due to their hydratable skeletons, and solar‐absorbing nature. Here, we report in situ polymerized Fe2O3@PPy/chitosan hydrogels as lightweight evaporation structures for solar‐powered evaporation under brine solutions (3.5 wt%). The polymeric network of Fe2O3@PPy/chitosan hydrogels builds in cross‐linked macroporous water channels, self‐floating, and a wide range of omnidirectional solar absorption (96%). The state‐of‐the‐art evaporation experiments demonstrate an efficient evaporation rate of water (1.80 kg m–2 h–1) and enhanced solar‐to‐vapor conversion efficiency (91%) as compared to other carbon‐based evaporation structures, excluding heat losses under 1 kW m–2 (one sun). Of note, the ultra‐black hydrogel surface stored enough thermal energy (39.6°C) under one sun solar irradiance due to the cationic polymeric network of Fe2O3@PPy/chitosan. A single‐step process for a freshwater supply that has been purified from various contaminants shows the potential of this device for real‐world applications. [ABSTRACT FROM AUTHOR]

Objectives Polygnum hydropiper L (Polygonaceae) is commonly known as smart weed. This study was designed to assess the effect of aqueous methanolic extract of P. hydropiper on oxidative stress and metabolic changes in fructose-induced hypertensive rats. Methods Male Sprague-Dawely rats were divided into six groups of five animals each (n = 5) and designated as normotensive group with distilled water, fructose-fed group with 10% fructose, standard control group with 10% fructose plus amlodipine (10 mg/kg) and treated groups with different doses of the aqueous methanolic extract of P. hydropiper (100, 200 and 400 mg/kg) plus 10% fructose daily for 6 weeks. Body weight gain was checked every week. Blood pressure parameters [systolic (SBP), diastolic (DBP), mean arterial pressure (MAP) and heart rate (HR)] and reactivity of extract with phenylephrine and adrenaline were measured by invasive method. Metabolic changes and oxidative stress parameters were measured from blood samples. Phytochemical analysis was also performed. Key findings Aqueous methanolic extract of P. hydropiper at 400 mg/kg decreased the blood pressure, heart rate, body weight and produced significant effect on metabolic and oxidative stress changes as compared to fructose-fed group. Phytochemical analysis revealed the presence of polyphenols and flavonoids in it. Conclusion The present results showed that aqueous methanolic extract of P. hydropiper possesses effect on oxidative stress and metabolic changes due to polyphenols and flavonoids.

Present study was conducted to validate the folkloric claims of Morus nigra L. (Moraceae) using invasive blood pressure measuring and ex vivo vasorelaxant experimental techniques. Intravenous administration of mn. aq in 0.01-30 mg/kg doses caused significant decrease in mean arterial pressure and heart rate in fructose-induced hypertensive rats. It also showed relaxation in high k+ [80 mm] and pe (1μm) mediated aortic contraction with ec50 1.25 and 3.72mg/ml values, respectively. Vaso-relaxant effect of mn.aq was partially blocked in presence of l-name with ec50, 5.32mg/ml value, but showed concentration dependent significant inhibition of ligand gated and voltage gated Ca+2 channels and intracellular ca+2 release, similar to verapamil. Findings of current study designate that aqueous fraction of M. nigra possesses antihypertensive activity with concentration-dependent vaso-relaxant effect predominantly mediated through endothelial-independent calcium channel blocking pathways accompanied by partial involvement of endothelium-dependent nos mediated relaxation.

Plants are considered as an essential source to treat different diseases. In traditional system of medicine, Juglans regia (J. regia) has been used in curing sinusitis and cough. The aim of the present study was to evaluate the anti-asthmatic activity of J. regia in ovalbumin-induced allergic asthmatic BALB/c mice. The mice were sensitized intraperitoneally and subsequently challenged with ovalbumin (intranasal) to induce allergic asthma. Mice were treated with methanolic, n-hexane and ethyl acetate extracts of J. regia and methylprednisolone for 7 consecutive days, along with intranasal challenge. The total and differential leukocyte counts in blood, bronchoalveolar lavage fluid (balf) and lung wet/dry ratio were determined. GC-MS analysis was also performed. The results showed that ethyl acetate extract of J. regia significantly reduced inflammatory cells count in both blood and balf more significantly. Lung wet/dry weight ratio was reduced in asthmatic mice treated with the different extracts of J. regia. Serum IgE antibodies level was also significantly decreased in extracts treated groups. GC-MS analysis of all three extracts of J. regia showed the presence of various phytochemicals responsible for its anti-inflammatory and anti-asthmatic activity. The results of the present study validated the traditional use of J. regia in respiratory disorders like asthma and sinusitis. [ABSTRACT FROM AUTHOR]

The aim of the present study was to evaluate the cardioprotective activity of boswellic acids in doxorubicin (DOX) induced cardiotoxicity. DOX (2.5mg/kg) was used intraperitoneally in rats to induce cardiotoxicity in six divided doses every alternate day over a period of two weeks. Dexrazoxane (10:1) was used as a standard drug. Boswellic acids (250, 500 and 750 mg/kg) were orally administered to rats for 14 days. After 14 days, rats were sacrificed, and blood was withdrawn through cardiac puncture. The blood lipid profile and cardiac biomarkers including LDH, CK-MB, CPK, SGOT and troponin T were measured. The heart of rats was isolated for histopathological studies. Graphpad Prism was used for statistical analysis. There was a significant increase in the level of cardiac enzymes and complete lipid profile parameters in diseased group as compared to control group. Pre-treatment with boswellic acids decreased level of all the measured parameters and decreased the severity of myocardial damage as supported by histopathological studies. It was concluded that boswellic acids possess cardioprotective potential by lowering cardiac biomarkers and blood lipid profile. Thus, boswellic acids might act as cardioprotective agent against doxorubicin induced cardiotoxicity. [ABSTRACT FROM AUTHOR]

Lactucaserriola(L. serriola), commonly known asprickly lettuce, is an annual and biennial herb. The plant is traditionally used as sedative, hypnotic, cough suppressant, expectorant, purgative, diuretic, vasorelaxant, demulcent, antiseptic and antispasmodic. Aim of present study was to evaluate protective effect of L. serriola in paracetamolinduced hepatotoxicity. Silymarin was used as a standard drug. Hepatoprotective effect of extract was determined by liver biochemical markers, anti-oxidant enzymes and blood lipid profile. Methanolic extract was found to be the most potent in in-vitro antioxidant assays and used for further studies. Treatment with paracetamol increased the level of hepatic biomarkers, blood lipid profile and decreased anti-oxidant enzyme levels. Pre-treatment with Lactuca serriola caused restoration of hepatic biomarkers, blood lipid profile and antioxidant enzymes. FTIR represented that L. serriola contains hydroxyl (-OH), carboxylic acid (C=O) and alkene (C=C) groups. HPLC analysis showed presence of polyphenolic compounds in the methanolic extract of L. serriola. It is concluded that the methanolic extract of Lactuca serriola possesses hepatoprotective potential that might be linked to the presence of polyphenolic compounds and their anti-oxidant activities.

The aim of the present study was to evaluate the hepatoprotective activity of Z. oxyphylla in paracetamol-induced hepatotoxic rat model. Silymarin was used as a standard drug. Methanol extract was found to be the most potent in in-vitro antioxidant studies. The methanol extract of Z. oxyphylla was administered to experimental animals. The hepatoprotective effect of extract was evaluated by measuring liver biochemical markers, anti-oxidant enzymes and blood lipid profile. Treatment with the paracetamol increased the level of hepatic biomarkers, blood lipid profile and decreased anti-oxidant enzymes. Pretreatment with Z. oxyphylla caused restoration of hepatic biomarkers, blood lipid profile and antioxidant enzymes levels. It is concluded that the methanol extract of Z. oxyphylla possesses hepatoprotective activity that might be due to quercetin and kaempferol glycosides present in the plant extract. Further studies are required to elucidate the exact mechanism of action of these isolated flavonoid glycosides. [ABSTRACT FROM AUTHOR]

In present investigation aqueous and methanolic extracts of Nelumbium speciosum flowers were screened for phytochemical constituents and antibacterial activity to ascertain their traditional use. Antimicrobial activity of both extracts was tested by Kirby-Bauer disc diffusion method against four Gram positive strains, viz. Staphylococcus aureus (ATCC25923), Streptococcus agalactiae (13813), Bacillus subtilis (ATCC 6633), Staphylococcus epidermidis (ATCC 12228) and four Gram negative bacterial strains Escherichia coli (ATCC 8739), Pseudomonas aeruginosa (ATCC 27853), Proteus mirabilis (12453) and Klebsiella pneumoniae (10031). Phytochemical analysis showed the presence of tannins, saponins and alkaloids in both extracts while flavonoids and steroids were present only in methanolic extract. Methanolic extract of Nelumbium speciosum flower showed concentration dependent antibacterial activity against all tested strains with maximum zone of inhibition (17.3±0.3mm) against P. aeruginosa. Aqueous extract showed concentration dependent activity against S. aureus, E. coli, B. subtilis and S. epidermidis with maximum antibacterial activity against E. coli (14.3±0.3mm). MIC of methanolic and aqueous extracts was in the range of 0.015-0.251 and 0.0625-0.251 mg/mL, respectively. Results showed that methanolic extract of Nelumbium speciosum exhibits superior antibacterial activity than aqueous extract. [ABSTRACT FROM AUTHOR]

The present study was designed to evaluate the effects of aqueous extract of Thymus serpyllum on lipid profile and some liver enzymes level in the diabetic rabbit. Rabbits were made diabetic with a single intravenous injection of alloxan and were divided into groups. Group 1 and 2 served as normal and diabetic control, respectively. Group 3 and 4 were given standard drugs glibenclamide and acarbose respectively while Group 5 was treated with 500 mg/kg of extract for 30 days. Blood samples were taken on day 0 and 30. The extract significantly reduced the level of serum cholesterol, triglyceride, LDLs, VLDLs, alkaline phosphatase and transaminases without affecting the HDLs level. Total cholesterol/HDL-cholesterol ratio was significantly reduced as compared to diabetic control. It is conceivable that T. serpyllum possesses antihyperlipidemic and hepatoprotective effects in diabetic rabbit. [ABSTRACT FROM AUTHOR]

The aim of present study was to evaluate and compare the hypoglycemic activity of different solvents extracts of Thymus serpyllum in rabbits. Diabetes was induced with single intravenous injection of alloxan monohydrate (150mg/kg). Glibenclamide and acarbose were used as standard drugs. The crude powder of Thymus serpyllum (500 mg/kg b.w) significantly reduced blood glucose level in both normal and diabetic rabbits. Various extracts of Thymus serpyllum were compared for their hypoglycemic activity in diabetic rabbits. Ether and aqueous extracts significantly reduced the blood glucose level with maximum effect (p<0.001) produced by aqueous extract, which was selected for further study. Aqueous extract significantly inhibited the rise in glucose level in oral glucose tolerance test. The extract showed synergistic effect with different doses of insulin; however serum insulin level of the diabetic rabbits was not significantly increased by the extract. HbA1c level was significantly (p<0.05) reduced whereas hemoglobin level was significantly increased in three months study. Phytochemical screening of the aqueous extract showed the presence of alkaloids, flavonoids, tannins, terpinoids, reducing sugar and cardiac glycosides. It is concluded that the aqueous extract might be used alone or in combination with insulin to manage diabetes and its associated complications. [ABSTRACT FROM AUTHOR]

The cardiovascular activity of aqueous methanolic extract of Paspalidium flavidum L. was evaluated on isolated rabbit heart and aorta. Heart rates, force of contraction and perfusion pressure were assessed in the presence of different concentrations of extract and adrenaline by using Langendorff's technique. Moreover, the vasoconstriction effects were studied in rabbit aorta using isolated organ bath. The results indicated that the extract (lng-lOOug/ml) exhibited a significant increase in heart rate, contractility and perfusion pressure of isolated rabbit's heart; with a maximum effect at 1ng/ml, which was comparable to adrenaline (1µg/ml). Similarly, adrenaline at doses from 1-10µg/ml produced a significant dose dependant increase in all the cardiac parameters. The cardiotonic effects of the extract were significantly blocked by propranolol (10-5M) while an increase in perfusion pressure was completely antagonized by verapamil (10-6M). Activity of cardiac marker enzymes was also significantly raised in the perfusate of isolated heart pretreated with the extract. In rabbit aorta, the extract exhibited a dose dependent vasoconstriction effect however it did not increase the tone of aorta when pre-treated with verapamil (10-6M). It is conceivable therefore; that the cardiotonic and vasoconstriction effects of the extract might be due to its agonistic actions on β-receptors and Ca+2 channels. [ABSTRACT FROM AUTHOR]

Purpose: To investigate the histopathological and cardiac depressant effect of the aqueous methanol extract of Caralluma tuberculata N.E. Br (AMECT) (family: Asclepiadaceae)' and to determine if there is a scientific basis for its cardiovascular diseases-related folkloric use. Methods: The effect of AMECT in different concentrations ranging from 0.00001 to 1.0 mg/mL were evaluated in isolated perfused rabbit heart to assess their effect on the force of contraction and heart rate using Langendorff's apparatus. Atropine and adrenaline were used to identify the underlying mechanism of response produced by AMECT. The extract was studied for its possible mechanism in the absence and presence of atropine and adrenaline. In addition, sub-chronic toxicity and histopathological study of heart tissues in rats were assessed by administering 500 mg/kg of extract. Results: At all concentrations, AMECT produced significant (p < 0.001) negative ionotropic and negative chronotropic effects. The most significant effect was observed at 0.001 mg/mL and higher concentrations hence 0.001 mg/mL was selected for further studies. Pre-incubation with atropine did not significantly inhibit the effects of AMECT. However, AMECT significantly (p < 0.01) blocked the cardiac stimulant effect of adrenaline. In the histopathological studies, AMECT did not produce any significant cellular changes or signs of toxicity in the sub-chronic toxicity study. Conclusion: The cardiac-depressant responses of AMECT may involve the ß-adrenergic receptors in the myocardium of isolated rabbit heart thus confirming the rationale for its use in ethnomedicine for cardiac diseases.

Seeds of Ipomoea hederacea Jacq. (family: Convolvulaceae) are traditionally used to treat high blood pressure and cardiac diseases. Aim of the study: Present study was conducted to validate the traditional claim and explore the possible mechanism(s) of antihypertensive effects of I. hederacea. Aqueous-ethanolic extract and activity based fractions of I. hederacea were evaluated using invasive blood pressure measuring technique, isolated tissue experiments, fructose induced hypertension/metabolic syndrome and biochemical analysis.Phytochemical analysis of active fraction was performed with aim to identify chemical composition of I. hederacea seeds. LC-MS analysis was also performed to identify the compounds proposed to be present in active fraction of I. hederacea seeds. Crude extract/fractions of I. hederacea showed dose (0.01–100 mg/kg) dependent significant hypotensive effect in normotensive anesthetized rats, similar to verapamil (0.01–30 mg/kg). Pretreatment with hexamethonium and atropine mediated no significant changes in hypotensive effect of butanol fraction of I. hederacea (Ih.Bn) at 3 mg/kg dose. However, a significant decrease in the hypotensive effect of Ih.Bn 3 mg/kg (−34.82 ± 3.36%; p < 0.05) was observed in the presence of L-NAME (20 mg/kg). Similarly, Ih.Bn (3 mg/kg) showed no significant effect on angiotensin-II response. However, response of phenylephrine (45.60 ± 9.63%; p < 0.05) and dobutamine (18.25 ± 2.10%; p < 0.01) was significantly decreased in the presence of Ih.Bn 3 mg/kg. Ih.Bn also exhibited dose dependent (0.01–100 mg/kg) antihypertensive effect in fructose induced hypertensive rats, similar to verapamil (0.01–30 mg/kg). Concomitant treatment with Ih.Bn (3, 10 and 30 mg/kg) for six weeks showed a dose dependent profound protection with significant (p < 0.01) effect at 30 mg/kg against fructose induced basal mean arterial pressure (142.2 ± 4.62 mmHg). Ih.Bn did not significantly change response of PE, Ang-II and Epi was observed in invasive and ex vivo techniques. However, Ih.Bn significantly (p < 0.01; p < 0.001) prevented against decrease in vascular response of acetylcholine in anesthetized rats and in isolated aorta of rat. A significant dose dependent decrease in triglyceride and glucose level (p < 0.001), and increase in HDL level (p < 0.05) was observed in Ih.Bn treated groups. Results of LC-MS analysis of Ih.Bn showed the presence of 24 compounds that belong to different chemical classes, including carboxylic acid, flavonoids, oligopeptides and tripeptide that are known to have antihypertensive and vasorelaxant properties. Results of present study indicate the presence of hypotensive/antihypertensive effect in crude extract/fractions of I. hederacea with most potent effect shown by butanol fraction (Ih.Bn), possibly mediated through α 1 blocking, β blocking and iNOS/cGMP stimulating activity.

In the present study, the hepatoprotective activity of aqueous and ether extracts of Thymus linearis (250 and 500 mg/kg orally) was evaluated against carbon tetrachloride- and paracetamol-induced hepatic damage in mice. Serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) were assessed. Antioxidant activity of both the extracts was also determined using 1-1-diphenyl-2-picryl hydrazine (DPPH) scavenging method. The results indicated that both the extracts significantly produce a dose dependent reduction in serum levels of ALT, AST, and ALP when compared to carbon tetrachloride- and paracetamoltreated groups. The maximum effect in all the parameters was observed at a dose of 500 mg/kg. The extracts also demonstrated a significant antioxidant activity. LD50 of both extracts was found to be 1050 and 900 mg/kg respectively. It is conceivable that the hepatoprotective activity of T. linearis might be due to the presence of certain pharmacologically active compounds. [ABSTRACT FROM AUTHOR]

Background: Geranyl acetate, a compound found in plant oils, has been studied for its potential effects on renal and cardiovascular ailments., Objective: This study aimed to investigate the diuretic and anti-hyperuricemic properties of geranyl acetate in male Wistar rats using a hyperuricemia-induced rat model., Methods: Molecular docking studies were conducted to assess geranyl acetate's interactions with various targets. in vitro studies were performed to evaluate its scavenging ability and inhibition of xanthine oxidase, urease, and acetylcholinesterase. Subsequently, we administered different doses of geranyl acetate (25, 50, and 100 mg/kg) and a reference drug (furosemide) to the rats to assess their acute and repeated dose diuretic effects over seven days. To understand the diuretic mechanism, we used inhibitors, such as L-- NAME, indomethacin, and atropine, prior to administering geranyl acetate. We also tested the anti-hyperuricemic potential of geranyl acetate on hyperuricemic rats., Results: Molecular docking suggested strong binding between geranyl acetate and nitric oxide synthase. in vitro studies showed significant free radical scavenging activity and and inhibition of acetylcholinesterase, xanthine oxidase, and urease. The 100 mg/kg dose exhibited the most promising diuretic effects, with nitric oxide appearing to influence its action. Uric acid excretion increased at this dose, resembling allopurinol effects., Conclusion: Geranyl acetate has demonstrated significant diuretic and anti-hyperuricemic effects, likely influenced by nitric oxide release and inhibition of enzymes, like xanthine oxidase and urease. The findings have suggested potential benefits for individuals with kidney ailments, hypertension, and gout., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Traditional medicine has employed the plant Fagonia bruguieri DC. to alleviate inflammation, fever and pain. The goal of this study was to test the anti-inflammatory, analgesic and antipyretic properties of the methanol extract of whole plant of Fagonia bruguieri (F. bruguieri). The writhing test and Eddy's hot plate test were used to assess the analgesic potential of F. bruguieri at three different doses. Carrageenan-induced rat paw edema was applied to investigate anti-inflammatory activity, whereas antipyretic activity was estimated in Brewer's yeast induced pyrexia model. Flavonoids, alkaloids, saponins, tannins and glycosides were found in F. bruguieri's phytochemical analysis. F. bruguieri at 750 mg/kg reduced writhing count by 62.23 percent, while F. bruguieri enhanced latency in Eddy's hot plate test. In carrageenan-induced edema, F. bruguieri at 750 mg/kg exhibited considerable anti-inflammatory effect (41.11 percent) after 2 nd , 3 rd and 4 th hours of therapy. F. bruguieri was also found to show antipyretic properties. The anti-inflammatory, analgesic and antipyretic properties of F. bruguieri were confirmed in this study, which might be attributable to the presence of several phyto-constituents.

Antihypertensive studies on aqueous-methanolic extract prepared from seeds of Cydonia oblonga M. were carried out. The test extract in 200, 400 and 600 mg/kg doses was investigated in normotensive, high cholesterol and glucose fed hypertensive rats through non-invasive blood pressure measuring technique. Acute and sub-chronic toxicity studies were conducted in mice and rats, respectively. The test extract significantly decreased dose dependently the systolic, diastolic and mean arterial pressures. The test extract in 600mg/kg dose produced maximum effect and prevented rise in blood pressure of high cholesterol diet and glucose fed rats as compare to control in 21 days studies. The extract was found safe up to 4g/kg dose in mice. In sub-chronic toxicity study, no significant alteration in blood chemistry of extract treated rats was observed except reduction in the low density cholesterol levels. It is concluded that Cydonia oblonga seeds extract possess antihypertensive effect which supports its use in folklore.

Ziziphus oxyphylla Edgew (Z. oxyphylla) is a small shrub to a medium sized tree. The aim of the present study was to evaluate the hepatoprotective activity of Z. oxyphylla in paracetamol-induced hepatotoxic rat model. Silymarin was used as a standard drug. Methanol extract was found to be the most potent in in-vitro antioxidant studies. The methanol extract of Z. oxyphylla was administered to experimental animals. The hepatoprotective effect of extract was evaluated by measuring liver biochemical markers, anti-oxidant enzymes and blood lipid profile. Treatment with the paracetamol increased the level of hepatic biomarkers, blood lipid profile and decreased anti-oxidant enzymes. Pre-treatment with Z. oxyphylla caused restoration of hepatic biomarkers, blood lipid profile and antioxidant enzymes levels. It is concluded that the methanol extract of Z. oxyphylla possesses hepatoprotective activity that might be due to quercetin and kaempferol glycosides present in the plant extract. Further studies are required to elucidate the exact mechanism of action of these isolated flavonoid glycosides.

The current study was conducted to evaluate the anti-diabetic effect of polyherbal product "diabetic bal" in normal and alloxan induced diabetic rabbits. Glibenclamide was used as standard drug. Diabetes was induced by single i.v. injection of 150 mg/kg b.w. of alloxan monohydrate in rabbits. "Diabetic bal" (250 and 500 mg/kg) significantly decreased the blood glucose level both in normal and diabetic rabbits in dose dependent manner. In oral glucose tolerance test, "Diabetic bal" demonstrated a significant inhibitory effect on rise of blood glucose level compared to control. "Diabetic bal" showed synergistic anti-hyperglycemic effect with dif- ferent units of insulin in diabetic rabbits. The "diabetic bal" decreased the glucose level and prevented the weight loss of diabetic rabbits as compared to control for an extended period of one month. It caused a significant increase (p < 0.001) in the insulin level of treated diabetic rabbits in 30 days study. In addition AST, ALT, ALP, cholesterol, LDLs, VLDLs and triglyceride level were significantly reduced whereas HDLs level was sig- nificantly elevated in diabetic rabbits with 500 mg/kg dose. The herbal product did not cause any significant change in CBC as compared to normal control in diabetic rabbits for one month. It is conceivable; therefore, that "diabetic bal" is effective in diabetes and its associated complications which support its use in folklore.
