There were no studies about the analgesic effect of silymarin in the chicken. This study examined antinociceptive effect of silymarin given intraperitonially in 7-9 day-old chicks. The median effective dose of silymarin for the induction of analgesia to electric stimulation in the chicks was 65.3 mg/kg. Silymarin at 60, 120 and 240 mg/kg revealed analgesic effect to electric stimulation in chicks in dose dependent manner in comparison with the control group. The analgesic effect of silymarin at 120 and 240 mg/kg started at 15 min after injection and lasted after over 120 min of injection were as silymarin at 60 mg/kg the analgesic effect started at 15 min after injection and declined before 120 min of injection. The peak of analgesic effect for 60, 120 and 240 mg/kg were at 60 min after injection. These results indicate that silymarin have an analgesic property in the chicks model.

The herbal drugs have a protective effect for kidney function against chemical toxicity. 24 male rats divided into 4 groups and treated as following, control group administrated orally with 1ml/kg. B.W physiological solution (0.9%), One dose Carbon Tetrachloride (CCl4) 3 ml/kg. B.W, Silymarin 150 mg/kg. B.W and Silymarin150 mg/kg. B.W with CCl4 3 ml/kg. B.W for 30 days. Oxidative stress resulted by CCl4 caused increasing in Creatinine, Urea, total protein, Albumin, malondialdehyde (MDA) levels decreasing in Glutathione (GSH) and superoxide dismutase (SOD) levels in serum and congestion, degeneration and desquamation in kidney tissue. We concluded that Silymarin showed protective effect via increasing GSH, decreasing creatinine, Urea, total protein and MDA levels in serum and protect kidney tissue in rats.

The present study aimed to investigate the role of silymarin as an antioxidant and/or it activity in induction of the endogenous antioxidants in intact adult male rats. Seventy males were randomly devided into control and  silymarin treated groups (35 each), and were drenched with drinking water and silymarin suspension (200 mg/ kg b.w) daily for 40 days. Each group was allocated to 5 equal subgroups; sacrificed before treatment (0 day), and after 10, 20, 30, and 40 days of treatment. At the end of each period, males were anaesthesized, dissected and blood samples were obtained for assessment of MDA, SOD, CAT and GSH concentrations. liver samples (1 g) have been removed and homogenized for assessment of liver subcellular MDA, SOD, CAT and GSH concentrations. At the end of each periods, serum and liver subcellular MAD concentrations showed no significant changes between groups, whereas SOD, CAT, and GSH concentrations significantly increased at 10, 20, 30, and 40 day periods in silymarin treated males compared with control. It can be concluded that silymarin antioxidant activity is of pharmacological value not only as an antioxidant by itself but also as an inducer of endogenous enzymatic and non-enzymatic antioxidants even in normal intact male.
