    Anthropometric study of patients treated for clubfoot
    (Lippincott Williams & Wilkins, 2003) Kesemenli, CC; Kapukaya, A; Subasi, M; Necmioglu, S; Arslan, H; Ozbag, D; Çelik, Y
    The anthropometric characteristics of patients treated for clubfoot were used to investigate whether the dimensions of the foot were affected by the method of treatment. A total of 68 patients followed up for an average of 9 years were divided into three groups: group 1, conservatively treated; group 2, surgically treated; group 3, conservatively treated on one side and surgically treated on the other. The following average discrepancies in foot length were obtained: group 1, 0.91 cm; group 2, 1.5 cm; group 3, 1.09 cm. Toe lengths were shorter to the same extent as the other dimensions of the foot. These discrepancies were statistically significant. The following average discrepancies in foot width were obtained: group 1, 0.05 cm; group 2, 0.37 cm; group 3, 0.054 cm; these were insignificant. The authors believe that the degree of discrepancy may depend not solely on the method, but on the severity of the deformity as well.

    The comparative investigation of morphology of papillary muscles of left ventricle in different species
    (Wiley, 2005) Ozbag, D; Gumusalan, Y; Demirant, A
    The papillary muscles of the heart are conical projections into the respective chamber of myocardium covered by endocardium. Functionally, the papillary muscles are important part of the respective valve complex. They prevent the cusps of a valve from being everted when the ventricle contracts. Our study was conducted on papillary muscles in left ventricle of 135 normal adult hearts (20 humans, 25 dogs, 60 sheep and 30 goats). The length (L), width (W), head number (HN), angle with ventricular wall (A degrees), distance with annulus (AnD) and apex (ApD), and the shapes of the anterior and posterior papillary muscles were observed. The tendinous chords (CTN) attached to each papillary muscle were counted at their origin. The values of both anterior and posterior papillary muscles were not statistically significant (p > 0.05) in measurements of L, W, HN, A degrees and AnD of all species, but those of CTN and ApD were significant (p < 0.05) between human and animal hearts, while the difference was not significant (p > 0.05) between sheep and goat hearts. Knowledge of morphology of papillary muscles in different species will be of much use to clinical investigators in their studies.

    Influence of ovariectomy and flutamide treatment on vaginal tissue and body weight
    (Saudi Med J, 2005) Saruhan, BG; Ozbag, D; Gumusalan, Y; Ozdemir, N
    Objective: To determine the effect of flutamide on vaginal histology, and to ascertain whether flutamide regulates body weight gain in the ovariectomized rat model. Methods: We chose 36 sexually mature female Wistar-Albino rats in this study. The study took placed in the Department of Medical Science Application and Research Center of Dicle University, Diyarbakir, Turkey, in 2002. We divided the model rats into 3 groups: group 1 - control group, group 2 - sham-operated group and group 3 - bilaterally ovariectomized group. In addition, we gave flutamide to group 3. Results: We found that the body weight was higher in the ovariectomized rats than the control rats. Furthermore, the body weight decreased a little after flutamide therapy. The thickness in the vaginal epithelium of the control group decreased, moreover, the appearance of stromal tissue was rather loose. After flutamide applications, infiltration of the stromal cells increased, the vaginal epithelial layer thickened and became keratinized. Microscopic papillae and anatomical processes appeared in the flutamide treated group. Conclusion: We observed that the antiandrogen drug flutamide is hormonally active and may exhibit estrogenic-antiestrogenic activity in rats. Our study may be a source for further research examining the relationship between. the androgen receptor antagonist flutamide and reproductive function in female rats.

    The investigation of perivasculary space under the myocardial bridge in different species
    (Wiley, 2004) Ozbag, D; Kervancioglu, P
    Our purpose in this study was to investigate the perivasculary space under the myocardial bridges (MB) in dog, sheep, goat and human hearts. A total of 160 hearts were studied, and perivasculary space under the myocardial bridges was examined under microscope. The specimens belonged to 25 dogs, 100 sheep, 25 goats and 10 humans. Special attention was paid to evaluate the distance between the MB and coronary arteries (CA), CA and underlying myocardium (UM) and to find the relation of concomitant vein number accompanying the CA and MB. 219 myocardial bridges were found in total of hearts, and specimens from these bridges were examined under microscope. There were large variations in distance between the MB and CA (0-714 mum) and distance between CA and UM (0-309 mum). The myocardial bridges were classified into three groups in terms of the number of veins accompanying CA, the bridges with no concomitant veins with one concomitant vein and with two concomitant veins. This suggests that the distance between the MB and CA is crucial to determine how much force is on the CA. The environment surrounding the CA may be a crucial factor in determining whether the MB influences the induction of heart disorders or not.
