The present investigation was aimed to study the anti-diabetic and hypolipidemic potential of Cinnamon cassia (Lauraceae family) bark in streptozotocin (STZ)-induced diabetic rats. The preliminary phytochemical analysis (hexane, petroleum ether, chloroform, ethanol, methanol, and aqueous extracts), GC-MS analysis (ethanol), in vitro (aqueous, ethanol and methanol), in vivo (ethanol) and in silico anti-diabetic activity with hypolipidemic effect of C. cassia bark was analysed. The ethanolic extract of the C. cassia bark has a fine inhibitory activity than the aqueous and methanolic extract. Out of 20 different compounds identified, seven compounds were biologically active, and 9-octadecenoic acid has highly interacted with PPARα/γ in docking studies. The levels of diabetic markers, enzymes, and lipid profiles were altered in STZ-induced rats, but after the treatment of C. cassia, the levels were returned to the normal. The study may prove the ethanolic extract of C. cassia has a powerful anti-diabetic and anti-hyperlipidemic activity. [ABSTRACT FROM AUTHOR]

The medicinal properties of Cinnamon cassia (C. cassia) bark have been reported for their clinical importance for many diseases including diabetes. However, there is no clear evidence so far regarding dose selection for its hepato- and nephroprotective effect in diabetic condition. Hence, the present study aims at evaluating in vitro antioxidant activity, the acute toxicity, and dose fixation of C. cassia bark for their effective medicinal values in streptozotocin (STZ)-induced rats. All the extracts exhibited potential in vitro antioxidant activity and showed a dose-dependent (1000, 2000, 3000, 4000, and 5000 mg/kg BW) acute toxicity by in vivo model. The levels of aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), urea, and creatinine showed a significant elevation in animals treated with the highest dose. In further studies along with histopathological studies, animals treated with STZ (60 mg/kg BW) followed by a different dose (300, 400, and 500 mg/kg BW) of ethanolic extract of the C. cassia bark and glibenclamide (3 mg/kg BW) revealed that the altered level of mitochondrial enzymes, hepatic, and renal marker in STZ-induced animals were restored in C. cassia bark extract-treated group as of control. These results could be of scientific support for the use of the ethanolic extract of the C. cassia bark in folk medicine for the management of diabetes and its associated complications.

Comparisons of (228)Ra and (226) Ra radium isotopes in the Bay of Bengal show that (228)Ra is a usable tracer for calculating mixing rates between low and high salinity waters of the Bay's north and south regions, respectively.

The reactions of five haloethyl radicals with H atoms are studied by the infrared chemiluminescence method in a flow reactor at 298 K. The multiple reaction channels, including C-Br rupture and 1,1-HX elimination as well as 1,2-HX elimination of the haloethanes are discussed.

The present study was carried out to evaluate the in vitro cytoprotective effects of Psidium guajava and their isolated quercetin fraction to reduce the CCl4 (carbon tetrachloride) induced toxicity in HepG2 cell lines (Hepatocellular carcinoma G2). Silymarin was used as a standard drug to compare the protective effects of plant extracts in infected cell lines. MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl-tetrazolium bromide) assay, cell viability assay, leakage parameters [Aspartate aminotransferase (AST), Alanine aminotransferase (ALT) and Lactate dehydrogenase (LDH)], lipid peroxidation and reduced glutathione (GSH) levels were used to find out the protection of human derived HepG2 cells against CCl4-induced damage. The levels of cytotoxicity, viability and GSH were reduced. While the activities of AST, ALT, LDH and lipid peroxidation was increased in CCl4-treated groups. The treatment of P. guajava and their isolated quercetin fractions (100, 200, 300 µg/mL) decreased the elevated levels of all these parameters. The results of the present study suggest that the ethanolic extract of P. guajava leaf and their isolated quercetin fractions can able to reduce the CCl4-induced cytotoxicity in HepG2 cell lines.
