Objective: Obstruction of the urinary tract has marked effects on renal blood flow, glomerular filtration rate (GFR), and tubular function. Ureteral obstruction results in an injury response that can progress to irreversible renal fibrosis and tubular damage by apoptosis. Materials and Methods: Forty five rabbits aged 13-17 weeks with body weights of 1250-1750 grams were divided into 4 groups. Group 1 underwent a sham operation and group 2 had unilateral ureteral ligation to cause total obstruction. Groups 3 and 4 also underwent unilateral ureteral ligation but with verapamil given on day 0 and day 7 respectively. Apoptosis to the renal tubules were assessed after nephrectomy on day 14 using immunohistochemistry by counting the number cell deaths/high power field (hpf). Results: The groups that received verapamil showed significantly less apoptosis compared to those without verapamil (2,73 vs 12,46 cell deaths/hpf; p<0,05). However, there was no significant difference between groups 3 and 4 (2,73 vs 2,89 cell deaths/hpf; p>0,05), although both groups still showed more cell deaths compared to group 1 (0,38 cell deaths/hpf). Conclusion: Verapamil appears to significantly decrease apoptosis during total unilateral ureteral obstruction. However, it cannot replace the benefit of relieving total obstruction

Together with the development of peritoneal dialysis (PD), appropriate animal models play an important role in the investigation of physiological, pathophysiological and clinical aspects of PD. However, there is still not an ideal experimental PD animal model. In this study, 45 Sprague-Dawley rats were divided into three groups. Group 1 (n=15) was receiving daily peritoneal injection through the catheter connected to the abdominal cavity, using PD solution containing 3.86 % D-glucose. Group 2 (n=15) was receiving daily peritoneal injection of 0.9 % physiological saline through a catheter. Group 3 (n=15), which was subjected to sham operation, served as controls. Our results showed that WBC counts in peritoneal effluent of Group 1 were slightly higher than those of Group 2 and control group, respectively (p<0.05). However, there was no episode of infection in any group. In addition, there was no significant difference in neutrophils fractions among these three groups. Hematoxylin-eosin and Masson’s trichrome staining demonstrated a dramatic increase in thickness of the mesothelium-to-muscle layer of peritoneum exposed to high glucose (Group 1) compared to Group 2 and controls (p<0.01). These data indicated that we established a novel rat model of PD with a modified catheter insertion method. This model is more practical, easy to operate, not too expensive and it will facilitate the investigate of long-term effects of PD.

Objectives: We aimed to evaluate the effectiveness of sesamol in preventing the progressive renal damage caused by complete unilateral ureter obstruction (CUUO). Methods: Twenty four Wistar rats were separated into three groups: In the group 1 rats (the sham-control, n = 8), the ureters were exposed and manipulated, but not ligated. In the group 2 rats (CUUO-untreated, n=8), CUOO was accomplished by double-ligating the left ureter using 5-0 silk ties. In the group 3 rats (CUUO -Sesamol treated, n=8), CUOO was created as in the Group 2 rats, also given sesamol daily, commencing on the day of CUUO surgery. The rats’ left kidneys were examined histologically and biochemically within the 8th day Results: Histopathological total score, apoptotic index and MDA values in the group 2 show a significant increase when compared to the group 1. These values were significantly decreased in the group 3 rats when compared to the group 2 rats. Tissue GPx value in the group 2 show a significant decrease when compared to Sham-control group. However, these values were significantly increased in the group 3 rats when compared to the rats 2. Polymorph nuclear leukocyte infiltration in peritubular areas was observed in group II, with moderate interstitial fibrosis and tubular dilatation. Despite the presence of dilated tubule structures in group III, this group showed less bleeding, leukocyte infiltration, and fibrosis than group II. Conclusion: The results of this study have shown that CUOO-induced renal damage can be reduced using sesamol, possibly due to its antioxidant properties. The mechanism by which sesamol causes these effects merits further investigation. Keywords: Complete unilateral ureteral obstruction, renal damage, sesamol, oxidative stress, rat.

ObjectivesThe aim of this study was to establish quantitative values for asymptomatic and symptomatic Achilles tendons.DesignCohort study with a single (cross-sectional) time point of patients diagnosed with unilateral Achilles tendinopathy and an asymptomatic group with comparative homogeneity.MethodsA sample of 50 participants: 25 diagnosed with symptomatic unilateral Achilles tendinopathy (AT group) and 25 with asymptomatic Achilles tendons (control group 2). The asymptomatic side of the AT group was used as a control (control group 1). Measurements at 2 cm intervals on the tendon from its insertion at the calcaneum up to the musculotendinous junction were taken non-weight bearing (NWB) and weight bearing (WB) using the MyotonPRO.ResultsThere was a significant (p<0.005) decrease in natural oscillation frequency (F) at points 2, 3 and 4 of the AT group (NWB condition) and points 2 and 3 for the WB condition. There was a significant (p<0.005) increase in logarithmic decrement (D) at points 2 and 3 signifying a decrease in elasticity. Dynamic stiffness (S) was significantly (p<0.005) reduced in the AT group at points 2 and 3 WB and point 3 WB. There was no significant difference in creep (C) observed between the symptomatic and asymptomatic tendons. There was a significant (p<0.005) increase in mechanical stress relaxation time (R) at point 2 NWB.There was a correlation between body weight and gender on tendon mechanics, with the symptomatic tendons. No significant differences were observed between the control group 1 and control group 2.ConclusionsThe MyotonPRO measured decreased stiffness over a section of the tendon corresponding clinically with Achilles tendinopathy. This may have potential in identifying risk of injury and informing rehabilitation, however further extensive research is required to generate baseline data for specific population groups monitoring variables over time. Age, gender and body mass index appear to have some bearing on the mechanical properties of the tendon but mainly in the tendinopathy group.

The aim of this study was to investigate the frequency of nocturnal sperm emissions (NSE) in varicocele patients after varicocele surgery. A total of 127 patients, 96 varicocele (Group 1) and 31 patients with inguinal hernia (Group 2) were included in this study. Mean age, laterality of surgical procedures, spermiogram results, marital status, and postoperative serum hormone levels were noted for all patients. Two groups were compared in terms of Beck depression score (BDS) and anxiety scores (AS). The frequency of NSE and libido changes in the patients during 10 days postoperatively was evaluated. The number of the patients who had NSE and increased libido were significantly higher in the varicocelectomy group when compared with the control group. No significant difference was noted between the groups in terms of BDS, AS, and serum hormone levels. No association was reported between BDS, AS, and serum hormone levels and the presence of NSE in Group 1. The incidence of NSE was higher in younger men. Increased libido was significantly associated with NSE in Group 1. Cord dissection during surgery may be a factor on increased frequency of NSEs in varicocele patients.

Study Objective: To know about the effects of cryotherapy and active stretching together and active stretching alone for improving hamstring flexibility in asymptomatic individuals. Method: 22 subjects were participated in study of the age 18 to 40. Subjects were randomly and equally assigned to static stretching and cryotherapy (group 1) and only active stretching (group 2). Subjects in each group were given stretching and cryotherapy for three weeks. Pre and post assessment of ROM was measured by the KEA, SLR and Sit and reach test. Results: After three weeks of intervention there was a significant difference between pre intervention and post intervention score in both the group but in group 1 showed significant difference between KEA, SLR and SRT variables. Conclusion: Subject who received active stretching and cryotherapy showed better improvement than the control group who received only active stretching. Hence it can be concluded that active stretching along with cryotherapy can improve hamstring flexibility than the active stretching only. Key words: Cryotherapy, flexibility, ROM, active stretching.

Abstract Background: Premature ovarian failure is among the most important side effects of chemotherapy during reproductive period. Preserving ovarian function is gradually gaining importance during oncologic treatment. The present study aims to investigate the potential of melatonin to protect from cisplatin-induced ovarian toxicity in rats. Twenty nine female rats were divided to three groups: Saline control group (Group 1), cisplatin group (Group 2), and cisplatin+melatonin group (Group 3). While the rats in Groups 2 and 3 were administered 5 mg/kg single dose of cisplatin via intra-peritoneal (IP) route, the rats in Group 3 were started on melatonin (20 mg/kg IP) before cisplatin administration and continued during 3 consecutive days. Ovaries were removed one week after cisplatin administration in all groups. Blood samples were obtained before the rats were decapited. Histological evaluation, follicle count, and classification were performed. TAp63 mRNA expression was evaluated using mRNA extraction and real-time polymerase chain reaction (PCR) method. Serum estradiol (E2) and anti-mullerian hormone (AMH) values were measured with enzyme immune-assay technology. Results: While primordial follicles were seen to decrease in Group 2 as compared to Group 1 (p:0.023), primordial follicle count was observed to be preserved significantly in melatonin group as compared to Group 2 (p:0.047). Moreover, cisplatin-induced histo-pathological morphology was preserved in favor of normal histology in melatonin group. A significant difference was not observed between groups with regard to mean serum AMH and E2 values (p:0.102 and p:0.411, respectively). While TAp63 gene expression significantly increased in Group 2 as compared to control group (p:0.001), we did not detect a statistically significant difference in cisplatin+melatonin group, although gene expression decreased (p:0.34). Conclusion: We conclude that concurrent administration of melatonin and cisplatin may protect from ovarian damage.

SummaryIntroduction: During the last years, many endovascular techniques have been developed in order to eliminate not only the reflux in stem veins but in perforating veins and their tributaries, too.Aim: The aim of this study was to use endo -vascular RFITT and the foam sclerotherapy for the occlusion of perforating veins as the prime source of reflux and their tributaries.Material and Methods: The Celon method was used for the thermal treatment. Polydocalon with the concentration 1% and 2% with DSS technique was used for the foam sclerotherapy. The RFITT was accomplished in 127 perforating veins in total. This group was divided into three subgroups. The first one consists of patients where only RFITT was carried out (n= 41), in the second, there were patients with RFITT realized with sclerotherapy during one session (n= 48), in the third, RFITT was completed with sclerotherapy in one month after the RFITT intervention (n= 38). The control group included perforating veins treated only with sclerotherapy (n= 81). The power setting 6W was used on the generator during the RFITT with CelonProSurge micro and 18W for usage of Celon ProCurve probe.Results: The effectiveness of the procedure in the group 1 was 8.8%, in the group two 93.7%, in the group three 92.1% and in the control group 76.5% in one year follow up. There was no significant difference between the effectiveness in groups 1, 2 and 3. The marginal difference was among all three groups with RFITT and the control group. Significant differences were in the parameter of the extinction of visible varicose veins with the reflux from perforators. The extinction was faster in group 3 than in group 2 and in the control group and the slowest was in group 1. The significant difference was observed between groups 2 and 3 compared with group 1 and the margin difference was between groups 2 and 3 compared with the control group. No significant difference was observed between groups 1 and the control group.Conclusions: All procedures are effective. The most important is the combination of RFITT and the sclerotherapy one month after thermal intervention. This is associated with a low risk of recanalization and the fastest extinction of visible varicose veins.

ABSTRACT Objective: To determine the serum levels of malondialdehyde and nitrite in patients with sickle cell anemia treated or not with hydroxyurea in outpatient's setting. Methods: Of the 65 patients with sickle cell anemia selected for the study, 51 were not treated with hydroxyurea (Group 1), 14 made chronic use of hydroxyurea (Group 2) and 20 individuals had no hemoglobinopathies (Control Group). Results: The Control Group had a lower and more homogeneous concentration of malondialdehyde levels as compared to the other groups. The results of Groups 1 and 2 showed increased values of malondialdehyde levels when compared to the Control Group. Considering the values of Groups 1 and 2, there were no significant changes in the malondialdehyde levels. There was no significant difference in the serum levels of nitrite between the groups. Group 2 presented a statistically significant correlation between serum malondialdehyde levels and the clinical variables investigated. In turn, Group 1 showed correlation only with occurrence of three or more vaso-occlusive crises. There was no correlation between nitrite levels and the clinical variables. Conclusion: The results revealed that during the pathogenesis of sickle cell anemia, an increase in lipid peroxidation was observed. On the other hand, no changes in oxidative parameters were detected during treatment with hydroxyurea, probably due to the short period of treatment of the patients studied.
