Anti-diabetic properties of Tinospora cordifolia stem extracts on streptozotocin- induced diabetic rats

The oral administration of various extracts (hexane, ethyl acetate and methanol) of Tinospora cordifolia stem (TCS) were found to have potent antidiabetic activity that reduces blood sugar level in streptozotocin-(STZ) induced diabetic rats. In this study, the chronic (100 days) antihyperglycemic effect of the extracts at a dose of 250 mg/kg b.w.p.d of TCS were investigated. Insulin was used as a...

The influence of gentamicin and erythromycin on glucose excursion after oral glucose loads was evaluated in twelve New Zealand rabbits, weighting between 1278 and 1861 g. The rabbits were randomized into three equal groups and were given either 5 mg/kg of Gentamicin i.m., 50 mg/kg of Erythromycin per oral or 0.9% Saline. One hour later, all the rabbits were given 2.5 g/kg of glucose per oral in 5 mls of 0.9% saline....

Phytochemical and antimicrobial screening of crude extracts from the root, stem bark, and leaves of Terminalia glaucescens

The root, stem-bark and leaves of Terminalia glaucescens were investigated for activity against some pathogenic organisms. Phytochemical screening revealed the presence of alkaloids, tannins, saponins, steroids, flavonoids, anthraquinones and phlobatannins (mostly in root and stem-bark). The results of in-vitro antimicrobial screening of the crude methanol extract exhibited a wide range of activity...

PAMAM-drug complex for delivering anticancer drug across blood-brain barrier in-vitro and in-vivo

The delivery of anticancer drugs to the brain is profoundly limited by blood-brain barrier (BBB)The purpose of this work is to develop a new carrier for doxorubicin to overcome the BBB. Polyamidoamine (PAMAM) dendrimer, a novel nanoscopic high-branching polymer, was exploited as an efficient carrier of doxorubicin. The MTT assay showed that PAMAM (generation 3) had little cytotoxicity in brain capillary endothelial...

Effect induced by hemisuccinate of pregnenolone on perfusion pressure and vascular resistance in isolated rat heart

Experimental studies suggest that pregnenolone can regulate blood pressure. Nevertheless, there is scarce information about the effects of pregnenolone and its derivatives at cardiovascular level. In addition, to date the cellular site and mechanism of action of pregnenolone at cardiovascular level is also unclear. In order, to clarify on those phenomena, we evaluated the effects of pregnenolone and hemisuccinate of...
