PORTULACA oleracea , *ALLODYNIA , *MEDICINAL plants , *TAILS , *FIBERS - Abstract
Background: Portulaca Oleracea is a medicinal plant with many effects including analgesic and antiinflammatory properties. This study aimed to investigate the effect of alcoholic extract of Portulaca Olerecea on CCI model of neuropathic pain (Bennet & Xie model) and acute thermal pain induced by Tail Flick. Materials and Methods: Adult male Wistar rats weighing 200-250 g were used. Sensitivity to mechanical stimuli (mechanical allodynia) and noxious thermal stimuli were evaluated by Von Frey filaments and Tail Flick, respectively. In neuropathic pain studies, animals were randomly assigned to five groups of sham, CCI, two groups subjected to CCI and injected with extract (200 and 400 mg/kg, i.p.) and a group subjected to CCI and injected with normal saline. In these groups, mechanical allodynia was assessed on day 7 after surgery. In acute pain studies, animals were divided to three groups of a group that received normal saline and two groups that received extract (200 and 400 mg/kg, i.p.). In these groups, Tail Flick was measured 30 minutes after normal saline or extract administration. Data were analyzed by SPSS and appropriate statistical tests. Results: All of the rats that had experienced CCI, exhibited mechanical allodynia after neuropathy. Portulaca oleracea could reduce the development of mechanical allodynia after CCI at 200 and 400 mg/kg doses. Thermal acute pain was reduced by 400 mg/kg of the extract. Conclusion: Our findings indicate that Portulaca Oleracea extract can reduce behavioral symptoms of neuropathic and acute pain. [ABSTRACT FROM AUTHOR]

REACTIVE oxygen species , *CARBOXYMETHYLCELLULOSE , *DIABETES complications , *RESVERATROL , *CARDIOVASCULAR development - Abstract
Background: Individuals with diabetes mellitus are at serious risk of a wide range of cardiovascular complications. Urotensin 2 and its receptors play an important role in the development of cardiovascular diseeases through production of reactive oxygen species (ROS). Resveratrol is a polyphenol with antioxidant and anti-diabetic properties. The present study aimed to investigate the effects of resveratrol on urotensin 2 and its receptors in the heart tissues of diabetic rats. Materials and Methods: In this experimental study, 48 male Wistar rats were divided into six groups (N= 8 in each group). Resveratrol was prepared in 0.5% carboxymethyl cellulose and given to the rats through oral gavage. At the end of the 60 days of treatment with resveratrol, rats’ heart tissue was collected. Results: The weight of diabetic rats treated with 10 and 90 mg/kg bw of resveratrol significantly increased compared with the diabetic group. Furthermore, the serum levels of FBS, lipids, MDA, CK-MB and LDH decreased in the treated diabetic rats compared with the control group. Moreover, concentration of urotensin 2 and its receptors significantly decreased in the heart tissues of the diabetic rats treated with resveratrol at the dose of 10 mg/kg bw compared with the control group. Conclusion: The current study indicated that resveratrol decreased FBS, lipids, weight, MDA and cardiac enzymes. Furthermore, resveratrol significantly reduced urotensin 2 and its receptors, which indicates its moderating effect on diabetes complications. [ABSTRACT FROM AUTHOR]

- Abstract
Background & Objective: The aim of this study was to evaluate the association between blood concentration of vitamin D and cardiovascular diseases, with regard to the percentage of ejection fraction, the number of coronary artery blockage, concentration of homocysteine, CRP and Ca. Materials & Methods: In this case-controlled investigation, 433 people who referred to Bushehr Heart Center for medical examination participated. Based on the preliminary results of clinical tests including ECG, echocardiogram, and angiography, the participants were selected and divided into case and control groups. Venous blood samples were collected (10 ccs) and immediately centrifuged and the serum samples were separated and stored at -80 ᵒC until analysis. The ejection fraction was recorded and the serum samples were processed for the measurement of 25-hydroxyvitamin D, homocysteine, calcium and CRP concentration. Results: The mean concentration of vitamin D in the serum of case group was significantly lower than that of the control. Moreover, the mean percentage of EF in the control group was significantly higher than that of the control group. Furthermore, the serum level of vitamin D and the atherosclerosis of coronary arteries were inversely correlated. Moreover, the mean concentration of CRP was significantly higher in the case group than in the control gorup. Conclusion: The result of this study showed that low serum levels of vitamin D may be related to cardiovascular disease. Moreover, vitamin D levels were inversely associated with the number of atherosclerotic arteries in men only. [ABSTRACT FROM AUTHOR]

- Abstract
Background: This study aimed to evaluate the relationship of serum levels of vitamin K2 and osteocalcin with coronary artery plaques in people undergoing angiography. Materials and Methods: This case-control study enrolled 138 people presenting to Bushehr Heart Center for routine examination. Demographic information of the participants was registered in a standard questionnaire. Before undergoing angiography, 10 ml blood was collected from all the participants and stored at - 80 °C until the analysis. After the angiography, those who were found to be normal entered the control group, and those with one or more arteries blocked were placed in the case group. Finally, serum levels of vitamin K2 and osteocalcin were measured in all the samples using ELISA kits. Results: Serum levels of osteocalcin in the case group were significantly higher than those of the control (P=0.019). There was no difference in K2 levels between the two groups (P=0.84). Moreover, no relationship was found between the osteocalcin levels and the number of blocked arteries and the severity of atherosclerosis (P=0.95). By adjusting age and type 2 diabetes in both groups, a difference was observed in the concentration of osteaocalcin and coronary artery atherosclerosis (P=0.034). Conclusion: Our results showed that a significant relationship exists between increased concentration of serum osteocalcin and coronary artery atherosclerosis. However, no such a relationship was observed between the serum levels of K2 and atherosclerotic arteries. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Resveratrol is one of the most effective natural polyphenolic compounds synthesized by plants and its beneficial effects on glycemic control have been reported. Considering the prevalence of thyroid disorders in diabetic patients and the effect of resveratrol on metabolic pathway through Sirtuin1 receptors and its ability to change iodine absorption in thyroid gland, it is suspected that this compound might influence thyroid function and possible have goitrogenic effects. Materials and Methods: This study enrolled 50 subjects with type II diabetes in an intervention and a control group. Patients received 500 mg resveratrol capsules twice a day for 45 days and subjects in the control group received equivalent placebo capsules. Thyroid function tests including T3, T4, TSH and T3RU and anti TPO were checked just before the study and after 45 days. Results: Regarding past history and clinical and biochemical parameters including BMI, blood pressure and glycemic control, there was almost no significant difference between the two groups. Anti TPO levels did not significantly change between the two groups during the study. Finally changes between the two groups were compared using Mann-Whitney U test, which concluded significant changes only in T4 levels between the two groups during the course of the study. Conclusion: We can conclude that taking resveratrol 1 gr a day for 45 days as a supplementary for lowering blood glucose in patients with type II diabetes does not cause goitrogenic effects. Further studies are suggested on resveratrol effects on thyroid function in humans with different doses and durations. Moreover, it is suggested that subjects with known thyroid disease with existing underlying pathology be studied to better understand its effects on thyroid function. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Resveratrol (RSV), one of the most effective natural polyphenolic compounds synthesized by plants, has antioxidant, anti-inflammation and anti-insulin-resistance properties. Some studies suggest that the mechanism of action of RSV is mainly mediated by the deacetylase Sirt1. However, other studies have shown that RSV plays its role through other metabolic routes such as its stimulatory effect on the secretion of adiponectin. Adiponectin is a hormone that plays an important role in the regulation of insulin sensitivity and energy homeostasis. In addition, RSV can control obesity by preventing the development of central leptin resistance. This study aimed to evaluate the effect of RSV on blood concentration of adiponectin and leptin in patients with type 2 diabetes. Materials and methods: This double-blind randomized clinical trial recruited 51 patients with type II diabetes from a previous study. Patients’ demographics and medical history were recorded in an interview. The intervention group received 500 mg RSV capsules twice a day for 45 days while the control group received identical placebo capsules. Blood pressure, weight, BMI, lipid profile, blood levels of adiponectin, leptin and liver function tests were measured at baseline. Data were analyzed using descriptive statistics and independent t-test in SPSS 18. Results: There were no differences in the concentration of adiponectin and leptin between the two groups. However, Mann-Whitney test revealed a difference in the concentration of leptin between intervention and control groups (p= 0.025). That is, the blood level of leptin was significantly more in the intervention group. Conclusion: The results of this study suggest that supplementation of 1 g per day of RSV for 45 days has no effect on the blood level of adiponectin and leptin in patients with type 2 diabetes.
