Moreover, medically assisted procreation, which helps in numerous fertility problems, raises the question of new viral risks linked to the application of these new technologies. In this review, we shall consider current knowledge in terms of the presence of HSV 2 and HCMV in the different parts of the genital tract of immunocompetent or immunodepressed men. We shall also consider the possibility of viral transmission by the sexual act or by the various techniques used in medically assisted procreation. We shall describe studies in human beings and in animals.展开更多

Methods: Thirty-six cases of atypical GH were diagnosedclinically, and their case histories, symptoms and signs wererecorded in detail and followed up. Polymerase chain reaction(PCR) was adopted for testing HSV2-DNA with cotton-tippedswabs. Enzyme-linked immuno sorbent assay (ELISA) forserum anti-HSV2-IgM was done to establish a definitivediagnosis. Other diagnoses were excluded at the same time bytesting for related pathogens including fungi, Chlamydia,Mycoplasma, Treponema pallidum, gonococci, Trichomonas,etc. Results: The main clinical manifestations of atypical GHwere: (1) small genital ulcers; (2) inflammation of urethralmeatus; (3) nonspecific genital erythema; (4) papuloid noduleson the glands; (5) nonspecific vaginitis. Twenty-three cases(64%) tested by PCR were HSV2-DNA sera-positive, and 36cases (100%) anti-HSV2-1gM sera-positive by ELISA. Conclusion: atypical HSV is difficult to be dinosed. But the combination of PCR and ELIAS will be helpful to thediagnosis of atypical HSV.展开更多

All 10 investigated mushroom species inhibited the reproduction of influenza virus strain A/FM/1/47(H1N1) in MDCK cells reducing the infectious titer by 2.0–6.0 lg ID50. Four species, Pleurotus ostreatus, Fomes fomentarius, Auriporia aurea, and Trametes versicolor, were also determined to be effective against HSV-2 strain BH in RK-13 cells, with similar levels of inhibition as for influenza. For some of the investigated mushroom species—Pleurotus eryngii, Lyophyllum shimeji, and Flammulina velutipes—this is the first report of an anti-influenza effect. This study also reports the first data on the medicinal properties of A. aurea, including anti-influenza and antiherpetic activities. T. versicolor 353 mycelium was found to have a high therapeutic index(324.67), and may be a promising material for the pharmaceutical industry as an anti-influenza and antiherpetic agent with low toxicity. Mycelia with antiviral activity were obtained in our investigation by bioconversion of agricultural wastes(amaranth flour after CO2 extraction), which would reduce the cost of the final product and solve some ecological problems.展开更多

The result showed that the infection rates of HSV2 in the samples of cervical cancer.chronic cervicitis and normal epithelial cells were 1 4. 41 %(16/111). 27.94%( 19/68) and 25.58% ( 11/43),respectively. It was implied that early stages carcinogenesis of cervical epithelial cells might be correlated with the HSV2 infection.Sixteen HSV 2 positive samples of cervical carcinomas were also examined for the presence of the sequences homologous to human papillomavirus (HPV) type 6B/11. 16 and 18 DNA using dot blot hybridization (Tm17℃). The result indicated that 13 out of 16 were HPV 16 DNA hybridization positive accounting for 81. 2% of all HSV-2 positive samples and none of them were positive for HPV type 6B/11 and 18. The result indicated that double infection of HSV 2 and HPV16 in the same cervical carcinoma tissues may provide a strong evidence of the viral synergistic interaction in the induction of female cervical展开更多

Aim: The study aimed at evaluating the CD4+ T cell count among women of reproductive age co-infected with human immune virus, hepatitis surface antigen and herpes simplex virusin Kogi state, Nigeria. Methodology: 342 females of reproductive age within the ages of 15 - 49 years participated in this study. They were recruited from various local government areas of three Senatorial districts of Kogi state. Blood samples were collected from participants and analyzed for HSV1/HSV2, HIV, HBsAg and CD4 using different scientific methods and procedures. Results: There was no significant differences in mean CD4+ T cell counts between subjects who tested positive and those who tested negative for only HSV1 (p = 0.61), HSV2 (p = 0.95), HIV (p = 0.48) and co-infection for HSV1, HSV2, HIV (0.68). In contrast, mean CD4+ T cell count was significantly higher in those who tested positive compared with those who tested negative for HBsAg alone (p = 0.03) and those co-infected with HSV1, HSV2, HBsAg (p = 0.01). Analysis of variance (ANOVA) indicated no significant differences in CD4+ T cell counts among the different classes of infections. Conclusion: This study shows no decline in the count of CD4+ T cell on the co-infections of HSV1, HSV2 and HIV, but higher significant difference in those co-infected with HSV1, HSV2 and HBsAg was recorded among the women of child bearing age in Kogi state.展开更多
