title: Picroliv affects gamma-glutamyl cycle in liver and brain of Mastomys natalensis infected with Plasmodium berghei.
abstract: Picroliv, the standardized preparation of iridoid glycosides from Picrorhiza kurrooa, at the dose of 6 mg/kg, po for two weeks provided significant protection against depletion of reduced glutathione levels in liver and brain of Plasmodium berghei infected Mastomys natalensis. The activation of gamma-glutamyl transpeptidase enzyme and decreased levels of cysteine, sulphydryl groups as well as glutathione synthesis in both tissues due to P. berghei infection were reversed by picroliv. Enzymatic and non enzymatic lipid peroxidation in microsomes in vitro was significantly reduced by picroliv along with the recovery of reduced glutathione.
