Anti-HCV antibody presence in hemodialyzed patients: assessment after one year regarding some preventive measures chosen.

The authors report on the presence of anti-HCV antibodies in a uremic chronic (UC) patient population after 6 months and 1 year with regard to certain selective preventive measures. The nonincreased number of HCV-positive subjects among the UC population could lead to the conclusion that the risk of environmental spreading of HCV is less than the risk of HBV diffusion.

[Intraserosal proximal hemideferentectomy versus classical proximal hemivasectomy in the rat. Anatomo-functional aspects and proposal for a new terminology]. / La emideferentectomia prossimale intrasierosa versus la emivasectomia prossimale classica nel ratto. Aspetti anatomo-funzionali e proposta di una nuova terminologia.

According to new trends and terms in microsurgery, the intra-serous proximal hemideferentectomy is compared to the classical vasectomy in rat. The effects of these surgical models are evaluated on morphological and functional bases. The anatomo-pathological parameters considered (stenosis and leakage of the anastomosis of the epididymal tubule conseguent on local ischemia) have been correlated with functional parameters "in vitro" (spontaneous motility and field stimulation) in order to plan the best microsurgical procedure in the experimental tubulo-vasostomy.

[Effects of tubulo-deferens stenosis secondary to intraserosal proximal hemideferentectomy and end-to-end tubulo-vasostomy on the testicle of the rat. Histopathological aspects]. / Effetti di stenosi tubulo-deferenziale secondaria ad emideferentectomia prossimale intrasierosa e tubulo-vasostomia termino-terminale sul testicolo di ratto. Aspetti istopatologici.

The histopathological aspects of the testis in rat after intra-serous proximal hemideferentectomy and end-to-end tubulo-vasostomy are evaluated. The histomorphometric variations of the convoluted seminiferous tubules and the quantitative modifications of the stages of spermatogenesis are correlated with the obstruction's degree of the tubulo-deferential anastomosis.

[Method for the characterization of peripheral lymphocytes in humans and their significance]. / Metodica per la caratterizzazione dei linfociti periferici nell'uomo e loro significato.

The Authors describe a technique for the identification of the lymphocytic subpopulations of peripheral human blood. It is pointed out the importance of using iron powder, AET, 20 hours incubation. The percentages of cells forming E rosets in patients suffering of acute lymphatic leukaemias and in normal subjects is valued.
