In Vivo Evaluation of Antidiarrhoeal Activity of Rhus Semialata Fruit Extract in Rats

Rhus semialata Murr. (Anacardiaceae) is a deciduous tree of north eastern India. The fruit of this plant is traditionally used to control diarrhoea and dysentery. The Present study was undertaken to evaluate anti-diarrhoeal potency of methanol extract of fruits of R. semialatalts indicated that the methanol extract of the fruits of R. semialata possesses significant anti-diarrhoeal effect and substantiated the use of this herbal remedy as a non-specific treatment for diarrhoea in folk medicine

Identification and isolation of ATP transport protein in mycobacillin sensitive Aspergillus niger.

The temperature sensitive release and uptake of ATP through the Aspergillus niger G3Br membrane vesicles followed saturation kinetics. Both the processes which occurred in the absence of mycobacillin were greatly enhanced by its presence. Liposomes prepared with antifilipin sterol and lipid showed the release and uptake of ATP in the presence of filipin, but no such uptake and release was seen with antimycobacillin sterol and lipid in the presence of mycobacillin. However the liposomes supplemented with Aspergillus niger membranes protein (s) showed the release and uptake of ATP, implicating membrane protein as a carrier in the transport process.

Effects of aspirin and paracetamol on ATPases of human fetal brain: an in vitro study.

In vitro effects of aspirin and paracetamol at the doses 200, 400, 600, 800 nmole/mg protein on ATPases activity were studied in the cerebrum and cerebellum of human fetus covering the age range from 10 weeks to 32 weeks of gestation. Both aspirin and paracetamol inhibit Na+K+ ATPase and Mg2+ ATPase in a dose dependent manner. The inhibition of Na+K+ ATPase and Mg2+ ATPase activity which may affect the release and uptake of biogenic amines in CNS, hinders the maturation of human fetal brain.
