Influence of Pre-treatment of Withania somnifera Root Extract and Cow Urine on Hemato-biochemical Parameters in Acetaminophen-induced Toxicity in Swiss Albino Male Mice

Background: The present study was undertaken to investigate protective activity of W. somnifera root extract (W.S.R.E.), cow urine (C.U.) and their combination against acetaminophen (APAP) induced toxicity in male mice. APAP also known as paracetamol, is a well-known drug used for its analgesic and antipyretic effects. However, outside of the therapeutic window, the toxicity may result. W.S. and C.U. are from indigenous sources of plant and animal origins, respectively with several therapeutic activities. Methods: Sixty adult swiss albino male mice were randomly divided into six groups, comprising of ten mice in each group. Group I (control group) received 2% gum acacia suspension for 14 days orally and on day 14, 0.9% NaCl (@300 mg/kg b.wt.) intraperitoneally was administered after 30 min of prior treatment of various agents. Group II, III, IV, V and VI received 2% gum acacia, silymarin (@25 mg/kg b.wt.), W.S.R.E. (@100 mg/kg b.wt.), C.U. (@7.8 mL/kg b.wt.) and W.S.R.E. (@100 mg/kg b.wt.) and C.U. (@7.8 mL/kg b.wt.) co-treatment orally for 14 days and on day 14, APAP (@300 mg/kg b.wt.) intraperitoneally was administered after 30 min of prior treatment of various agents as mentioned. On 15th day, the animals were sacrificed and samples were collected to study various hematobiochemical and growth related parameters. Result: The treatment of acetaminophen caused significant decrease in haemoglobin, total erythrocyte count whereas increase in total leucocyte and prothrombine time. There were significant (p£0.05) decreases in plasma total protein, albumin and globulin values in group II (APAP), as compared to control (group I). Treatment with W.S. +C.U attenuates these alterations. W.S.R.E., C.U. and their combination pre-treatment mildly restored the changes to normal observed following APAP exposure in mice. However, the results of co-treatment group were more pronounced as compared to individual treatment groups. Thus, it was concluded that treatment with W.S.R.E. and C.U. curtailed the toxic effect of APAP, however, co-administration of both potentiated the protective effect.
