| Parvovirus B19 has been associated by some investigators with cases of severe hepatitis. The aim of the present study was to determine the presence of active parvovirus B19 infection among 129 Brazilian patients with non-A-E hepatitis. The patients were assayed for antibodies against parvovirus B19, IgM class, by ELISA. In IgM-positive cases, parvovirus B19 DNA was assayed by PCR in serum and liver tissue and parvovirus VP1 antigen in liver tissue was assayed by immunohistochemistry. Antibodies against parvovirus B19, IgM class, were detected in 3 (2.3%) of 129 patients with non-A-E hepatitis. Previous surgery and blood transfusions were reported by these 3 patients. One patient was a 56-year-old female with severe hepatitis, with antimitochondrial... |

| ABSTRACT The aim of this study was to describe population and morphological characteristics of preantral follicles of not pregnant cows, pregnant cows and fetus. Ten ovaries of non-pregnant Nelore cows, eighteen ovaries of pregnant cows and eighteen ovaries of fetus were used. For pregnant cows, six ovaries from each third (initial, middle and final) were evaluated, acquired from a slaughterhouse. For fetus, the same methodology and proportion of ovaries were used. Ovaries were washed, fixed and embedded in paraffin. They were then sectioned in longitudinal sections and stained by the Hematoxylin-Eosin method. Preantral follicles were classified according to morphology (primordial, primary and secondary) and degree of viability (intact and in initial,... |
