Infezioni cervico-vaginali da Chlamydia trachomatis in un campione di donne asintomatiche: confronto di quattro differenti
No full textIn campioni cervico-vaginali di 150 donne asintomatiche sono state messe a confronto 4 metodiche in uso per la ricerca di Chlamydia trachomatis. I risultati hanno confermato che l'immunofluorescenza diretta rappresenta la tecnica in grado di rilevare il maggior numero di casi positivi anche in assenza di sintom

SYNTHESIS AND BIOLOGICAL-ACTIVITY OF PYRIMIDO[2,1-B][1,3]THIAZINE, [1,3]THIAZINO[3,2-A]PURINE AND [1,2,3]TRIAZOLO[4,5-D][1,3]THIAZINO[3,2-A]PYRIMIDINE DERIVATIVES AND THIAZOLE ANALOGS
No full textSome series of thiazolo[3,2-a]pyrimidine, pyrimido[2,1-b] [1,3]thiazine, thiazolo[3,2-a]purine, [1,3]thiazino[3,2-a]purine, thiazolo[3,2-a][1,2,3]triazolo[4,5-d]pyrimidine and [1,2,3]triazolo[4,5-d][1,3]thiazino[3,2-a]pyrimidine derivatives, variously functionalized, were prepared. The compounds were tested for antimicrobial and antimycotic activity on a number of strains, namely: E. coli, Proteus vulgaris, P. mirabilis, Pseudomanas aeruginosa, Salmonella sp., Staphylococcus aureus, S. faecalis, Bacillus subtilis, Sarcina lutea, Candida albicans, C. tropicalis, Aspergillus sp., and for antiviral activity on Herpes simplex virus Type 1, Vesicular stomatitis virus and Coxsackievirus B5. The compounds proved to be devoid of activity against viruses and gram-negative bacteria, while some of them exhibited modest activity against gram-positive bacterial strains
IgG antibodies to papillomavirus genus-antigens in adult men with cancer of the urinary bladder
No full textForty-five sera from men with bladder cancer were examined in a micro solid-phase enzyme-linked immunosorbent assay (ELISA) and in a Western-blotting (WB) assay for the presence of IgG antibodies to papillomavirus (PV) genus-antigens of bovine origin. The ELISA detected PV antibodies in 75.6% of cancer patients. This antibody frequency was significantly higher than that found in both healthy males (22.7%) and patients with urological disorders (24%). A similar correlation among the PV antibody frequencies of the three groups was found with WB assay: 60% of the neoplastic group showed PV antibodies versus 17.3% in healthy males and 32.6% in non-neoplastic patients. Within the same group, 78% to 87% sera showed the same reactivity to both assays. Of these concordant sera, PV positive sera were 55.6% in cancer patients, 13.3% in healthy adults and 19.6% in patients with urological disorders. ELISA PV antibody level in the cancer group was higher than in each of the two control groups. The meaning of the humoral response to PV genus-antigens in men with bladder cancer is discussed
