Objective To observe the effect of Modified Erzhi Pills (MEP) on free radicals and immunity in D-galactose-induced aging rats.Methods Sixty SD rats were randomized into 5 groups: normal group, model group, high-, middle-and low-dosage MEP groups (treated with gastric gavage of MEP 11.5, 7.0 and 3.5gkg-1d-1 respectively). Except the normal group, the rats in other groups received intraperitoneal injection of D-galactose (300mgkg-1d-1) to induce sub-acute aging rat models. After treatment for 2 months, superoxide dismutase (SOD) and malondialdehyde(MDA)levels in whole blood were detected, and the serum level of interleukin-2 (IL-2) and spleen index were examined.Results SOD level decreased, MDA increased, and IL-2 level and spleen index were decreased in the model group(P

Objective To study the mechanism of Chinese herbal capsule in the treatment of genital herpes.Methods Guinea pig model for genital herpes infection was established.HSV DNA from the cerebrum,spinal cord,cervical canal and vagina of guinea pigs was detected by fluorescent-quantitative PCR.Results The HSV DNA could be detected from all four kinds of tissues,with different copies of the virus in the different tissues,the highest in spinal cord,then in vagina,the least in cerebrum and cervical canal.There was statistical difference of HSV-DNA copies between herbal capsule group and control group(normal saline),whereas no statistical difference between herbal capsule group and aciclovir group.Conclusion The mechanism of the anti-virus herbal capsule in the treatment of experimental genital herpes might be related to blocking the latent infection and suppressing the replication of HSV.
