Abstract
Background: Varicocele is a dilated vein of the pampiniform plexus that cause to det-rimental time-dependent effects so this study describes the effect of varicocele on the level of IL-6 and interferon gamma in serum and testis tissue, number of sertoli and spermatogonia cells, seminiferous tubules diameter and sperm activity in immature rats.
Methods: Thirty six immature rats, 5-6 weeks aged were investigated in this study. The sham groups underwent sham operation and varicocele groups underwent partial liga-tion of the renal vein. Serum, testis and sperm samples were collected at 9, 11, and 13 weeks after induction of varicocele or sham operation to evaluate histological parame-ters (seminiferous tubules diameter, number of sertoli and spermatogonia cells), per-centage of sperm motility and viability and levels of cytokines. Testicular morphology was evaluated.
Results: Varicocele significantly caused an increase in serum and testis IL-6 and inter-feron gamma, compared to related sham groups and previous varicocele groups (P<0.05). Varicocele significantly caused decreases in sertoli cells and spermatogonia cells number with increasing varicocele time, compared to related sham groups and previous varicocele groups (P<0.05). In the evaluation of seminiferous tubules diameter external, internal and epithelium diameter were decreased compared to sham related groups and previous varicocele groups. In all varicocele groups, all kind of sperm motility and viability decreased compared to the related sham-operated groups (P<0.05). Varicocele had deteriorating effects on testis tissue because our observations in varicocele groups demonstrated that the external, internal and germinal epithelium height was reduced by the time and in the evaluation of testicular cells, sertoli and spermatogonia cells number were decreased by the time compared to sham related groups and previous varicocele groups.
Conclusion: This study suggests varicocele had a detrimental time-dependent effect on cytokines levels and decrease in sertoli and spermatogonia cells number, seminiferous tubules diameter and sperm indices.

Abstract
Background: Brucellosis is a systemic infection caused by gram-negative coccobacilli and facultative intracellular bacteria of the genus brucella. Brucellosis is a bacterial disease common to humans and livestock. Infection with Brucella spp. continues to pose a human health risk globally despite strides in eradicating the disease from domestic animals. The humoral and cellular immunity plays an important role in brucellosis. The effect of phagocytosis and cellular immunity has been demonstrated in brucellosis. The effect of cupping as a therapeutic method on bacterial diseases has been demonstrated. By considering this fact that cupping is an effective method on host immune system functions and has potential effect to regulate the inflammatory reactions.
Methods: This experimental study was carried out on 48 rats in 6 groups (48 rats were divided into 6 groups) during the first 6 months from January 2015 to July 2016 in the laboratory of microbiology and animal of Hamedan University of Medical Sciences. The rats were infected through the injection of Brucella melitensis with plenty 5×105 (cfu/ml) of bacteria. After a week, in order to approve the accuracy of the infection in the studied rats inoculated with coombos Brucella melitensis, Wright test, 2-Mercaptoethanol test and Coombs' Wright test were used. The rats were then treated with cupping method in their sacral area. IFN-γ was measured using enzyme-linked immunosorbent assay. And the study of tissues using hematoxylin and eosin (H&E) Staining.
Results: The results of this study showed that cupping leads to an increase in the mean serum level of interferon-gamma. The histopathological study of liver tissue showed that the radial arrangement was not observed in the infected group with brucellosis and the cells were acidophilus. While, the radial arrangement was observed in treated rats with cupping, but it was not complete. The number of enlarged sinusoids were reduced. But, cell infiltration was observed.
Conclusion: This study showed that cupping can increase serum level of IFN-γ, and thus help to the clearance of disease and improvement of injury in the brucellosis animals lab.
