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.

Newcastle disease is a highly contagious disease of domestic and wild birds result in huge economic losses due to extreme morbidity and mortality. The aim of this paper is to explore the possibility of the harmful impact of Newcastle disease vaccine on certain biochemical profiles regarded to chicken liver. This study conducted during January-April 2014, one day old - 53 chicks were divided into two groups; vaccinated (with Newcastle disease vaccine) group at the age of 1, 3, and 7 days and unvaccinated group. Results show damaging effects of vaccination on the liver glycogen and malondialdehyde concentrations, serum superoxide dismutase, catalase, glutathione peroxidase, gamma-glutamyl transferase, alanine transaminase, and aspartate transaminase activities. In contrast, studied parameters look to return to their usual range at the age of 30 days. From the convincing outcome of our investigation, it can be concluded that Newcastle disease vaccination has a detrimental influence on the liver of chickens, nonetheless this effect can be overwhelmed by the time.

The aim of this study was to detect the antioxidant effects of propofol in chicks by estimation of glutathione concentrationin blood plasma, brain and liver as well as total antioxidant capacity and antioxidant effects of propofol in vitro by usinghydrogen peroxide as oxidative stress. Propofol at 20 mg/kg, intraperitoneally significantly increased after 4 hours theconcentration of glutathione concentration in plasma and brain compared with the control group and with 5 and 10mg propofolgroups. Propofol at 5, 10 and 20 mg/kg, i.p significantly increased glutathione concentration in the liver compared with thecontrol group. Propofol at 5, 10 and 20 mg/kg, i.p increased the efflux rate constant by 882, 1031 and 920 %, increasedglutathione turnover rate by 880, 1028, and 917 % and decreased the turnover time by 89, 91 and 90% in the liver. In the brainpropofol at 5, 10 and 20 mg/kg, i.p increased efflux rate constant as 26, 600 and 2826 % and increased glutathione turnoverrate by 29, 616 and 2894 % and a decreased in the turnover time by 21, 86 and 96%. Propofol at 10 and 20 mg/kg, i.psignificantly increased after 20 hours the TAC in the serum of the chick by 38 and 48%, respectively compared with thecontrol group. Propofol at concentrations of 25, 50 and 100 micromoles / liter decreased erythrocyte hemolysis induced byhydrogen peroxide in vitro 10 micromoles / liter in a concentration depended manner by 25, 49 and 64 % respectively. In conclusion, Propofol have antioxidant effect in vivo and in vitro in the chicks. Propofol have a protection against oxidativestress.
