The Application Of Human Amniotic Membrane In Repairmen Of Dura Mater In Dogs

Volume 60, Issue 5 (15 2002)
Abstract
This study was conducted to show the comparison of efficacy and survival of amniotic membrane grafts and homologous dura grafts.
Methods and Materials: In this study, ten dogs (age 6-9 months & weight 15 lo 20 kg) have been chosen. The study was a single blind clinical trial. The dogs have been assigned into two groups by random allocation method. The amniotic membrane (A.M) was taken from a placenta belonging to a 38 weeks fetus delivered in a cesarean section surgery. In one group the graft was a peace of dura mater and in the other one the graft was a homologous dura graft. Maintenance of all cases was the same. Forty-five days later, another surgeon who was not aware of the assignment, conducted the second exploratory surgery for evaluation of the results.
Results: None of cases in two groups had any infection, abscess formation, fistula, CSF leakage or any toxic status. The healing process was normal in both groups.
Conclusion: There seems to be no difference between the (A.M) grafts and homologous dura in the repairmen of dura mater. This is expected to occur only if the pregnant woman is carefully tested for the presence of certain clinical conditions and the preparation of A.M is contemplated in an ideal environment.

Abstract
Background: Post-acrosomal sheath WW domain binding protein (PAWP) is one of sperm factors related to oocyte activation and is expressed in elongating spermatid. Previously, the effect of high of testicular temperature in infertile men with varicocele on semen quality, sperm DNA damage, expression of genes and proteins were reported. In this study, expression of PAWP at RNA and protein levels, and also sperm DNA damage were compared between fertile and infertile men with varicocele.
Methods: In this case-control study, semen samples were collected from 35 infertile men with varicocele (grade II & III) and 20 fertile men referring to Isfahan Fertility and Infertility Center from January 2016 to September 2016. Ejaculated semen was obtained by masturbation into a sterile plastic container after 3-5 days of abstinence and was allowed to liquefy at room temperature. Briefly, sperm concentration, motility and morphology were evaluated using a sperm chamber (Sperm meter; Sperm Processor, Aurangabad, India), Computer Assisted Semen Analysis (CASA, Video Test, ltd: version Sperm 2.1, Russia) and Papanicolaou staining, respectively. In addition, DNA fragmentation, expression of PAWP at RNA and protein levels were assessed by real-time PCR, and Western blot technique, respectively. Microsoft Excel 2013 (Microsoft Corp., Redmond, WA, USA) and Package for the Social Studies were used to analyze data. We used independent-samples t-test to compare the mean value between different groups. Differences with values of P<0.05 were considered as statistically significant.
Results: Mean of semen volume, sperm concentration, percentage of sperm motility, and expression of PAWP at both RNA (P=0.0001) and protein (P=0.03) levels were significantly lower in infertile men with varicocele in comparison with fertile men. In addition, mean percentage of sperm abnormal morphology and sperm DNA fragmentation were significantly higher in infertile men with varicocele in comparison with fertile men (P<0.05).
Conclusion: Expression of PAWP as a protein involved in spermatogenesis and fertilization process, has decreased in infertile men with varicocele. In addition, sperm DNA integrity was disrupted in these individuals that can be considered as a main etiology of infertility.
