The antimalarial sesquiterpene, artemisinin, is in short supply; demand is not being met, and the role of artemisinin in the plant is not well established. Prior work showed that addition of dimethyl sulfoxide (DMSO) to seedlings increased artemisinin in their shoots and this study further investigated that serendipitous observation. When in vitro-cultured(More)
In the present study, we evaluated the immunopotentiating efficacy of tuftsin against experimental murine aspergillosis in both normal and immunodebilitant BALB/c mice. The animals were challenged with an isolate of Aspergillus fumigatus (1x10(8) cfu/mouse) that was showing less susceptibility to lower doses of amphotericin B in murine animal model.(More)
Protein phosphatase 2A (PP2A) is a family of serine/threonine phosphatases that regulate multiple cellular signalling pathways involved in proliferation, survival and apoptosis. PP2A inhibition occurs in many cancers and is considered a tumour suppressor. Deletion/downregulation of PP2A genes has been observed in breast tumours, but the functional role of(More)
Aqueous extract of the root of P. vulgare (PV) produced CNS depressant effect. It decreased the spontaneous motor activity, prolonged the pentobarbitone induced hypnosis, reduced body temperature and increased the reaction time to pain stimuli. PV also caused prevention against supramaximal electroshock and pentylenetetrazol induced seizures. PV showed a(More)
Plasma free amino acids in the sub-totally nephrectomized chronic uremic rat have been quantitated. The concentrations of these substances in uremic rats have been compared to levels present in sham-operated controls, and to levels found in normal rats on a restricted diet. Phosphoserine, alpha-aminoadipic acid, 1-methylhistidine and 3-methylhistidine(More)
The present study demonstrates the biological activity of Ochthochloa compressa, since extensive literature survey has shown no documented biological activity of this plant. Ethanolic extract of whole plant was prepared and evaporated under reduced pressure by rota vapor. The crude extract was further fractionated into n-hexane, dichloromethane, ethyl(More)
The sub-totally nephrectomized chronically uremic rat has been found to have significantly increased hepatic glucose-6-phosphate dehydrogenase activity and increased lipogenesis and glycoportein synthesis. Increased conversion of 14-C-D-glucose to 14-CO2, and increased plasma free fatty acid levels were also observed. The metabolic significance of these(More)
Long term maintenance of male Wistar rats following sub-total nephrectomy has been shown to alter carbohydrate metabolism. These rats frequently became hypoglycemic and concurrently demonstrated increased hepatic glycogen stores. Chemical analysis of glycogen revealed a significant increase in branching, with a concomitant decrease in glucose residues per(More)
