Studies of various biochemical parameters of rat plasma following chronic administration of "Rohitakarista"-an Ayurvedic formulation.

The study was carried out to investigate the safety profile as well as the effect of "Rohitakarista" (RHT) on various biochemical parameters of rats' plasma after chronic administration. RHT, a classical Ayurvedic preparation used in hepatosplenic disorders, was administered per oral route at a dose of 100 mg kg(-1) body weight, once daily, up to 46 days for all the experiments. Forty albino rats (Rattus novergicus: Sprague-Dawley strains), equally of both sexes, were randomly grouped into four where each group had ten animal/sex. One male and one female group were used as control and other groups were used as test. In the male, rats there was a statistically insignificant increase (p = 0.763) in the total protein but there was a statistically significant increase (p = 0.022) in the total protein content of the plasma of female rats. Statistically very high significant increase (male: p = 0.001 and female: p = 0.001) in the albumin content of the plasma was noted in both sexes. In case of bilirubin, interestingly it was decreased very high significantly (p = 0.001) in plasma of male rats but increased very high significantly (p = 0.001) in the plasma of female rats. In the male rats, statistically there was a very high significant decrease (sGPT: p = 0.001, sGOT: p = 0.001 and ALP: p = 0.001) in the sGPT, sGOT and ALP activities in the plasma. On the other hand, statistically there was a very highly significant increase (sGPT: p = 0.001, sGOT: p = 0.001 and ALP: p = 0.001) in the sGPT, sGOT and ALP activities in the plasma of female rats. Very high significant decrease (male: p = 0.001 and female: p = 0.001) in creatinine in plasma of both sexes were observed after chronic administration of RHT. Urea in the plasma was decreased very high significantly (p = 0.001) in plasma of male rats but increased very high significantly (p = 0.001) in the plasma of female rats. There was high significant increase (p = 0.002) in uric acid in male rats. On the contrary, no significant increase (p = 0.324) of uric acid was observed in female rats.
