ABSTRACT

The role of liquid membrane phenomenon has been studied in the anti bacterial activity of cephalosporins i.e. Cefuroxime sodium. In our earlier publication [1] it was reported that hydraulic permeability data obtained to demonstrate the existence of liquid membrane in series with supporting membrane generated by Cefuroxime sodium. Transport of selected permeants (glucose, PABA, glycine, and ions like Mg(++), NH4 (+), PO4 (-), Ca(++), Na(+), K(+) and Cl(-)) through liquid membrane generated by Cefuroxime sodium in series with supporting membrane has been studied. The results indicated that the liquid membrane generated by Cefuroxime sodium inhibit the transport of various essential bio-molecules and permeants in to the cell. This modification in permeability of different permeants in the presence of the liquid membranes is likely to play significant role in the biological actions of Cefuroxime sodium. The anti-bacterial activity of Cefuroxime sodium further confirmed that the generation of liquid membrane by Cefuroxime sodium is also contributing for the antibacterial activity of them.

ABSTRACT

Hepatoprotective activity of 70% ethanolic extract of flowers of C. procera was studied against CCl4 induced hepatic injury in albino rats and mice. In addition, antioxidant activity was studied by in vitro models. Pre-treatment with 70% ethanolic extract (CPA) reduced the biochemical markers of hepatic injury like serum glutamate pyruvate transaminase, serum glutamate oxaloacetate transaminase, alkaline phosphatase, bilirubin, cholesterol, HDL and tissue glutathione (GSH) levels. Similarly pretreatment with CPA reduced the CCl4 induced elevation in the pentobarbitone sleeping time. Histopathological observations also revealed that pretreatment with CPA protected the animals from CCl4 induced liver damage. CPA demonstrated dose dependant reduction in the in vitro and in vivo lipid peroxidation induced by CCl4. In addition it showed dose dependant free radical scavenging activity. The results indicate that flowers of C. procera possess hepatoprotective property possibly because of its anti-oxidant activity. This property may be attributed to the quercetin related flavonoids present in the flowers of Calotropis procera.

ABSTRACT

Alcohol and water extracts of Abutilon indicum leaves (400 mg/kg, p.o.) showed significant hypoglycemic effect in normal rats 4 h after administration (23.10% and 26.95%, respectively).
