The purpose is to study the prophylactic and therapeutic effect of the traditional Chinese Medicine (TCM)-Jinyebaidu (JYBD) to guinea pig cytomegalovirus (GPCMV) intrauterine infection. The virus-free female and male guinea pigs were screened with nest-polymerase chain reaction (N-PCR). After inbred, pregnant guinea pigs were selected and divided into 3 groups randomly: 5 guniea pigs of the blank control group were not given either GPCMV or JYBD. 31 guniea pigs of the positive control group were inoculated 1 mL (10(7) TCID50) suspension of GPCMV intraperitoneal. 10 guniea pigs of the experimental group were inoculated GPCMV firstly and then perfused stomach with JYBD for 14 days (Dosage in accordance with the modulus of the weight ratio of human to guniea pig). The effects of JYBD on the intrauterine infection of GPCMV were observed. The results showed that JYBD could decrease the maternal infection rate from 100% (31/31) to 50% (5/10) (P < 0.001), the intrauterine infection rate from 100% (72/72) to 75% (21/28) (P < 0.001), and the rate of abnormal outcome of pregnancy from 64.4% (29/45) to 25.0% (7/28) (P < 0.001), the infective symptoms being relieved. It can be concluded that traditional Chinese medicine- JYBD can prevent and treat (GPCMV intrauterine infection, and can be expected a prophylactic drug for HCMV intrauterine infection.
