Primary ciliary dyskinesia (PCD), previously known as immotile cilia syndrome, can cause respiratory and reproductive problems. Because of the impaired motion of microtubules the patients suffer upper respiratory tract problems. Infertility is an other issue of these patients. Several attempt have been proposed to bring back sperm motion and to improve intracytoplasmic sperm injection (ICSI) results. With our case we have described the management of a male infertility that causes from immotile cilia. The role of ICSI with incubated and activated ejaculatory sperm by pentoxifylline in the patient of PCD or as commonly named immotile . . .cilia syndrome. © 2008 Springer-Verlag Daha fazlası Daha az

Objective: This experimental study was designed to evaluate the effect of granulocyte colony-stimulating factor (G-CSF) in ovarian ischemia and ischemia/reperfusion (I/R) injury. Study design: Forty-eight female adult Sprague–Dawley albino rats were divided into six groups as Group 1: sham, Group 2: torsion, Group 3: detorsion, Group 4: sham + G-CSF, Group 5: torsion + G-CSF, and Group 6: detorsion + G-CSF. Except for Groups 1 and 4, all groups underwent adnexal torsion bilaterally for 3 h. Adnexal detorsion was applied to Groups 3 and 6 for 3 h after a 3-h torsion period. The intraperitoneal injection of G-CSF (100 IU/kg) was admin . . .istered 30 min previously in Group 4, 5 and 6. At the end of the study process the animals were euthanized and their ovaries were removed for histopathological and biochemical analysis. Total oxidant status (TOS), total antioxidative status and oxidative stress index (OSI) concentrations were determined and compared. Histopathological examination of ovaries was performed for the presence of interstitial edema, congestion, hemorrhage and loss of cohesion to determine tissue damage. Results: In Group 3, 4, 5 and 6, TOS, OSI and total histopathological scores of ovarian tissue were higher than in the sham group (p Daha fazlası Daha az

Objective: To determine the effects of etanercept (anti-TNF-?) on surgically induced endometriosis in a rat model. Materials and methods: This is a prospective, randomized, controlled, experimental study that was carried out at the Experimental Research Center of Yeditepe University (YUDETAM). Thirty female nonpregnant, nulligravid Wistar-Hannover albino rats were used. The summary of the technique: surgical induction of endometriosis, administration of estrogen for 2 weeks, and laparotomy; administration of etanercept for 2 weeks following the induction of endometriosis and laparotomy; administration of estrogen for 2 weeks and nec . . .ropsy. The volume and histopathological scores of the endometriotic foci were evaluated. Results: One-hundred twenty uterine horns were implanted in 30 rats. Endometriosis was completely formatted in 112 lesions (93.3%). No rats were lost. In the etanercept group, the lesions' volumes were 83.9 ± 13.1, 47.2 ± 8.4, and 96.7 ± 34.8 mm3 at the end of the second week (pretreatment stage), at the end of the fourth week (post-treatment stage), and at the end of the sixth week, respectively (P = 0.007). Histopathologic scores were 2.3 ± 0.2, 1.7 ± 0.2, and 1.9 ± 0.1, respectively (P = 0.08). The changes in the other groups were not statistically significant. Conclusions: Etanercept, a fusion protein consisting of human recombinant soluble TNF receptor-2, neutralizes TNF activity. Anti-TNF therapy could be a new non-hormonal therapeutic option for the treatment of endometriosis in humans. © 2010 Springer-Verlag Daha fazlası Daha az

Aims: To determine the effects of different doses of melatonin treatment on endometrial implants, the activity of antioxidant enzyme superoxide dismutase (SOD), the angiogenesis factor, the vascular endothelial growth factor (VEGF) and the waste metabolite product of lipid peroxidation malondialdehyde (MDA) in an oophorectomized rat endometriosis model.Methods: Thirty-two, female, non-pregnant, nulligravid Sprague–Dawley, albino rats were used in this prospective, randomized, controlled and experimental study. Endometriosis was surgically induced in oophorectomized rats, and estradiol treatment was started after the first operation . . .and continued till the end of the study. Second look, third look and necropsy operations were performed in the 2nd, 4th and 6th weeks. Mean volumes, histological scores and biochemical parameters were evaluated throughout the study.Results: The mean volumes of endometriotic foci were 98.8 mm3 ± 17.2 vs. 108.2 mm3 ± 17.5, 54.1 mm3 ± 15.6 vs. 25.8 mm3 ± 3.6, 42.8 mm3 ± 10.5 vs. 32.7 mm3 ± 6.0 and histopathological scores were 2.2 ± 0.2 vs. 1.7 ± 0.1, 2.6 ± 0.2 vs. 2.2 ± 0.2, 2.6 ± 0.1 vs. 2.7 ± 0.2 in the 10 vs. 20-mg/kg/day melatonin group at the end of the second, fourth and sixth weeks, respectively. When the groups were compared, no significant differences were seen in the histopathologic scores, SOD and VEGF levels between the groups. However, the endometriotic foci volumes were significantly decreased in both melatonin treatment groups with respect to the control group at the end of the fourth and sixth weeks. Moreover, the mean MDA levels were significantly lower in the control group than in the 10-mg/kg/day melatonin group at the end of the fourth and sixth weeks.Conclusion: Melatonin treatment resulted in the regression of endometriotic lesions in oophorectomized rats. Higher doses of melatonin treatment might be more effective in the regression of implants and improvement of histologic scores as well as in the precise evaluation of SOD, MDA and VEGF distributions in the rat experimental models. © 2014, Springer-Verlag Berlin Heidelberg Daha fazlası Daha az
