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.

In order to assess the influence of finishing and polishing on the surface brightness and color stability of the ceramic veneer, fifty specimens were fabricated with 10 mm diameter and 2 mm thickness using IPS E-Max Ceramic. After glazing, 10 specimens were untouched as control group, and the other 40 specimens were abraded using 125µm diamond bur to create surface roughness. Forty specimens were divided into four groups (n=10), in group 1: specimens were finished using diamond point, in group 2 specimens’ surface was polished with a polishing kit, Group 3: Each specimen surface was polished with the polishing kit as in protocol 2 and was polished a polishing past and group 4 Each specimen was glazed by heating at 621℃ for 3 minutes followed by a temperature increase of 83℃/min up to 918℃ for 30 seconds. Color measurement was performed using spectrophotometer. Color stability data were analyzed using two-way ANOVA and Tukey’s HSD test (α=0.05). For Ra values, paired-samples t-tests were used to analyze the data and compare groups. The change in L and E showed a significant difference among the study groups; (group 1, group 2, group 3 and group 4) with respect to three variables L, a and b. A significant difference was noted when compared each group with the control; however, only group 2 showed a significant difference from group 4; the remaining groups demonstrated similar findings for all three variables. The study displayed a significant impact of the finishing and polishing technique on the surface brightness and color stability of ceramic restoration. However, it was evident that combination of two or three polishing techniques which includes polish kit and glaze enhances the surface finish and adds color stability by alternating the yellow – blue axis (increase in b) and red- green axis (decrease in a).
