Background. Genital human papillomavirus (HPV) infection is one of the most common sexually transmitted diseases, and it has been identified as a significant risk factor for the development of dysplasia and cancer of the uterine cervix. The possible influence of male HPV lesions on female cervix oncogenesis has not been elucidated so far. In the present study we evaluate the male partners of women with clinical or subclinical HPV infection with particular interest in the clinical features of this infection in both partners. Methods. We examined 81 male partners of women affected with human papillomavirus infections. Condylomata acuminata were searched for by visual inspection. Subclinical lesions were searched by 5 power optical magnification lens after application of 5% acetic acid. Results. In men we observed the following percentage of infection: 67% of the partners of women affected with condylomata acuminata, 46% of the partners of women affected with subclinical lesions (acetic acid positive), and 40% of the partners of women with association of HPV and cervical intraepithelial neoplasia. Conclusions. Our data stress that very often the partners of women with HPV subclinical infection, especially when associated with CIN, do not present lesions, and consequently primary prevention may be very difficult. 相似文献

The activity of 2-bromo-α-ergokryptine (bromocriptine) (5 mg kg?1, i.p.) on adenylate cyclase and on phosphodiesterase (PDE I-PDE II) of rat striatum, has been examined both in vitro and in vivo. In vitro and in vivo bromocriptine stimulated adenylate cyclase activity, but reduced the stimulating effect of dopamine on adenylate cyclase activity. Bromocriptine showed a dose-dependent biphasic action on phosphodiesterases in vitro while in vivo it stimulated them. The results obtained proved bromocriptine to have an agonist-antagonist action at striatal dopamine receptor level, with a relevant effect on the cAMP system. 相似文献

beta-Endorphin was measured by radioimmunoassay in post-mortem human brains. Samples of brain were taken from five discrete areas, both from control brains and brains of schizophrenic patients. No difference in beta-endorphin levels was found in these two groups of brains. beta-Endorphin was confirmed to be widely distributed in the brain, but there were considerable differences in the concentrations in different areas. 相似文献
