Abstract

Rotavirus induced diarrhoea was investigated in neonatal mice. Assessment of oxidative/antioxidative profile was the mechanistic approach to study the nature of injury. Neonatal mice (NMRI strain) were infected orally with the homologous strain of (EB) rotavirus (serotype 3). The peak severity of rotavirus infection was attained on the third day post infection. The whole small intestine of neonatal mice on day 3 post infection was homogenized and analysed for oxidative/antioxidative profile. Glutathione and related thiols were significantly declined in rotavirus infected group. Superoxide dismutase, glutathione peroxidase and glutathione-S-transferase (1-chloro 2, 4 dinitrobenzene) activities were also decreased in the rotavirus infected group. The activities of glutathione reductase and glutathione-S-transferase (ethacrynic acid) however were elevated with rotavirus infection in comparison to the control group. Similarly, ADP-FeCI3, NADPH induced lipid peroxidation was elevated with rotavirus infection. Thus the altered oxidative/antioxidative profile indicated the presence of oxidative stress in the rotavirus infected group and can be postulated to have a prominent role in the pathogenesis of the disease.
