Item Effect of long-term alcohol abuse on male sexual function and serum gonadal hormone levels(Akademiai Kiado Rt., 1998) Gümüş B.; Yiǧitoǧlu M.R.; Lekili M.; Uyanik B.S.; Müezzinoǧlu T.; Büyüksu C.Purpose: The relationship between chronic alcohol abuse and male sexual dysfunction and pituitary gonadal function abnormalities remains uncertain. The purpose of this study was to assess the effect of chronic alcoholism on sexual functions and serum hormone levels. Materials and methods: Forty-five chronically alcoholic men and a control group of thirty healthy non-alcoholic volunteers were enrolled in the study. Each of the men in the study and control group were interviewed according to a sexual dysfunction questionnaire by an urologist. Blood samples were collected for evaluation of hormone levels. Sera were stored at -70°C for analysis. Results: The sexual desire and erection scores of alcoholic men were not statistically different from those of the control group. Fourteen out of the 45 alcoholic men complained of loss of erection during sexual activity. No significant difference in hormone levels between groups was found except for FSH. Conclusion: In the absence of hepatic and gonadal failure in chronically alcoholic men, there is no significant difference in serum hormonal levels, sexual dysfunction form, and sexual functions between alcoholics and normal healthy nonalcoholic men.Item The effects of extensive vas mobilization on testicular histology during orchiopexy(Akademiai Kiado Rt., 1998) Lekili M.; Gümüş B.; Kandiloǧlu A.R.; Işisaǧ A.; Müezzinoǧlu T.; Büyüksu C.We were aware that extensive mobilization of vas deferens during orchiopexy could cause secondary infertility due to testicular damage and/or functional obstruction of the vas deferens. We decided to perform this experimental study in order to document the effects of this procedure on the testis. Thirty adult fertility-proven New Zealand white rabbits were randomly divided into 3 groups. Ten rabbits underwent extensive mobilization of the vas deferens and the other 10 rabbits had vasectomy on the left side. The remaining 10 rabbits were explored on the left side only and were considered sham controls. Four weeks later all rabbits underwent bilateral orchiectomy. Mean seminiferous tubular diameters and Johnsen's testicular biopsy scores were noted. Comparison of the three groups showed that vas mobilization and vasectomies cause no effect on the viability of testis, however, significant testicular histological changes, which were different from the controls and contralateral testis, were observed. We concluded that during any surgical intervention involving the inguinal canal, vascular and neural supports of the vas deferens should be preserved as much as possible in order to avoid iatrogenic damages to the testis.Item The anatomical studies on two biarum (Araceae) species in Turkey(Akademiai Kiado Rt., 2018) Akyol Y.; Durmuskahya C.; Yetisen K.; Kocabas O.; Özdemir C.In this study, anatomical properties of Biarum marmarisense (P. C. Boyce) P. C. Boyce and Biarum pyrami (Schott) Engl. var. pyrami were examined. The specimens were collected from Antalya province, South West of Anatolia. Degree of spathe tube margin connection, distribution of pistillodes and staminate-pistillate flower zone interstice length characters are important in Biarum Schott. taxonomy at specific level. The cross-sections of root, stem and leaf parts of the plant were examined and demonstrated by photographs. Although thicknesses of the cell wall of the endodermis and xylem strands are distinguishing features, raphide crystals are same feature in both species. B. marmarisense has observed paracytic stoma types while B. pyrami var. pyrami has anomocytic stoma types. Most of the anatomical properties were similar to the other members of the Araceae family. © 2018 Akadémiai Kiadó, Budapest.
