Effect of Picroliv on cadmium induced testicular damage in rat
چکیده انگلیسی

Ameliorative potential of Picroliv, a standardized extract of Picrorhiza kurroa on Cd induced early and advanced testicular damage was investigated in male rats. In the former experiment, the rats were administered Cd as CdCl2 (0.5 mg/kg, s.c.) 5 days/week for 18 weeks and Picroliv at two doses (6 and 12 mg/kg, p.o.) was given for the last 4 weeks i.e. from week 15 to 18, to the Cd administered group. In the latter experiment, the Cd administration continued for 24 weeks and Picroliv was given from week 21 to 24.At 18 weeks, Cd caused alterations in oxidative stress indices like increased lipid peroxidation (MDA) and reduced levels of non protein sulphydryls (NPSH). They were found close to the control values by Picroliv treatment, suggesting its antioxidant potential. The increased levels of Zn and Ca were reduced by Picroliv, the Cd levels remained unaltered. The Cd induced testicular damage was also mitigated by Picroliv. The higher dose (12 mg/kg) being more effective than the lower dose. However, at 24 weeks of Cd exposure, the oxidative stress indicators in testis were more pronounced along with the morphological alterations. These parameters remained unaffected by Picroliv treatment.On comparative evaluation of the two studies, 18 weeks Cd exposure caused moderate testicular damage, which could be reversed significantly by Picroliv administration and correlated well with oxidative stress markers.Our results clearly demonstrate the ameliorative potential of Picroliv in Cd induced early testicular damage.
