Sixty cases of rotaviral enteritis treated with Qiwei Baizhu Powder (QWBZP) revealed a better efficacy than that treated with Oral Rehydration solution (ORS, chi 2 = 6.07, P < 0.05). The content of Na+ and glucose as well as number of patients with positive human rotavirus (HRV) antigen in faeces in QWBZP group were less than that in ORS group (chi 2 = 18.09, P < 0.05). In experimental study, QWBZP was found to be effective in treating HRV enteritis of newborn NIH mice in vivo, as compared with the control groups, the mortality of mice was decreased by 73.3%, the content of Na+ and glucose as ...
