Protective effect of the whole plant extract of Evolvulus alsinoides on glycoprotein alterations in streptozotocin induced diabetic rats

The present study was carried out to evaluate the antidiabetic activity ofVinca roseamethanolic whole plant extracts in alloxan induced diabetic rats for 14 days. The methanolic whole plant extract at high dose (500 mg/kg) exhibited significant anti-hyperglycemic activity than whole plant extract at low dose (300 mg/kg) in diabetic rats. The methanolic extracts also showed improvement in parameters like body weight and lipid profile as well as regeneration ofβ-cells of pancreas in diabetic rats. Histopathological studies reinforce the healing of pancreas, by methanolicVinca roseaextracts, as a possible mechanism of their antidiabetic activity.

The present study was undertaken to investigate the protective effect of ethanolic citronella grass (C. nardus) leaves extract against mercury (Hg) induced glucose metabolism alteration in rats. Four groups of rats were selected, with 6 rats for each group. Animals of group I was received a 1 ppm of Hg only. Animals of groups II, III, and IV received a combination of 1 ppm Hg and plant extract in different dose (1650, 2520, and 3360 mg/ml). The experiment lasted for 4 weeks. The various parameters studied included liver weight, liver glucose, glycogen, and malondialdehyde (MDA) level in all groups after treatment. The results of this present studies showed that the Hg-induced glucose metabolism alteration in rats which can be seen from the increase of liver glucose and the decreasing of liver glycogen levels. The results also showed that the Hginduced glucose metabolism alteration through its activities in the trigger the liver cells damage which can be seen from the decreasing of liver weight and the increase of liver MDA level. The ethanolic of C. nardus leaves extract shows a protective effect to maintain all parameters into a better a condition which can be seen from the significant increase in liver weight and liver glycogen level, and the significant decrease in liver glucose and MDA levels. The present study indicated that the ethanolic C. nardus leaves extract showed a potential protective effect on glucose metabolism alteration induced by Hg

: Cissus aralioides is a medicinal plant used in sub-Saharan Africa for treatment of infectious diseases; however the chemical constituents of the plant have not been investigated. Thus, in this study, attempt was made at identifying predominant phytochemical constituents of the plant through chromatographic purification and silylation of the plant extract, and subsequent characterization using spectroscopic and GC-MS techniques. The minimum inhibitory concentration (MICs) for the antibacterial activities of the plant extract, chromatographic fractions and isolated compounds were also examined. Chromatographic purification of the ethyl acetate fraction from the whole plant afforded three compounds: β-sitosterol (1), stigmasterol (2) and friedelin (3). The phytosterols (1 and 2) were obtained together as a mixture. The GC-MS analysis of silylated extract indicated alcohols, fatty acids and sugars as predominant classes, with composition of 24.62, 36.90 and 26.52% respectively. Results of MICs indicated that friedelin and other chromatographic fractions had values (0.0626-1.0 mg/mL) comparable with the standard antibiotics used. Characterization of natural products from C. aralioides is being reported for the first time in this study.

Background and Objective: This study investigated whether rapamycin has a protective effect on the testis of diabetic rats by regulating autophagy, endoplasmic reticulum stress, and oxidative stress. Methods: Thirty male Sprague-Dawley rats were randomly divided into three groups: control, diabetic, and diabetic treated with rapamycin, which received gavage of rapamycin (2mg.kg-1.d-1) after induction of diabetes. Diabetic rats were induced by intraperitoneal injection of streptozotocin (STZ, 65mg.Kg-1). All rats were sacrificed at the termination after 8 weeks of rapamycin treatment. The testicular pathological changes were determined by hematoxylin and eosin staining. The protein or mRNA expression of autophagy-related proteins (Beclin1, microtubule-associated protein light chain 3 (LC3), p62), ER stress marked proteins (CCAAT/enhancer-binding protein (C/EBP) homologous protein (CHOP), caspase-12), oxidative stress-related proteins (p22phox, nuclear factor erythroid2-related factor 2 (Nrf2)) and apoptosis-related proteins (Bax, B cell lymphoma-2 (Bcl-2)) were assayed by western blot or real-time fluorescence quantitative PCR. Results: There were significant pathological changes in the testes of diabetic rats. The expression of Beclin1, LC3, Nrf2, Bcl-2 were significantly decreased and p62, CHOP, caspase12, p22phox, and Bax were notably increased in the testis of diabetic rats (P <0.05). However, rapamycin treatment for 8 weeks significantly reversed the above changes in the testis of diabetic rats (P <0.05). Conclusion: Rapamycin appears to produce a protective effect on the testes of diabetic rats by inducing the expression of autophagy and inhibiting the expression of ER-stress, oxidative stress, and apoptosis.
