To study the association between hepatitis B and schistosomiasis, 1,234 Egyptian males, ages 18 to 24, were interviewed, examined, and tested for Schistosoma mansoni infection and HBsAg. Sera from 91 (7.4%) of the study subjects were positive for HBsAg, and S. mansoni was found in the stools of 26.3%. There was no correlation between S. mansoni infection,(More)
A village, 20 miles north of Cairo, with a census population of 2010, was surveyed in 1976 by the Center of Disease Control (CDC) and the Egyptian Ministry of Health for hepatitis B surface antigen (HBsAg). Ninety individuals (47 males and 43 females were positive for HBsAg (a prevalence rate of 4.5%). Forty-two of the 47 males were the subject of this(More)
Three hundred twenty-four individuals in a farming village located in the Nile Delta of Egypt were serially tested for hepatitis markers and Schistosoma mansoni to determine whether there is an increased risk of hepatitis B in persons infected with schistosomiasis.

We examined the effect of parasitologic cure of S. mansoni infection on liver fibrosis in mice. Praziquantel, 250 mg/kg body weight, was administered orally to mice 8 weeks after infection with 50 S. mansoni cercariae. We assessed liver fibrosis by chemical measurement of collagen content as measured by the estimation of hydroxyproline and by histologic(More)
Advanced liver fibrosis is generally considered to be irreversible. We studied the reversibility of marked liver fibrosis in rabbits infected with Schistosoma japonicum. We determined liver collagen content, collagen biosynthesis, and collagenase activity using serial biopsy specimens obtained 20, 40, and 60 weeks after infection. Reversibility of this(More)
