    (2012) Ünal F.; Semizel E.; Serdar M.; Ecevit C.O.; Karaca Y.; Yilmaz E.M.; Kocaefe H.; Kasirga H.E.
    Introduction: Fecal calprotectin (FCP) can be found in high concentrations in inflammatory bowel disease due to the increase in leucocyte turnover in intestinal wall or increase of migration of neutrophils into the lumen. In this study, we aimed to determine the FCP values of the ulcerative colitis (UC) patients at the time of diagnosis and to investigate the applicability and effectiveness of this non-invasive method in the diagnosis of the disease, routinely. Materials and Methods: A total of 19 patients with UC (10 females, 9 males, age: 11.5±3.5 years old) whoose stool samples collected during the diagnosis period and 20 healthy controls (10 female, 10 male, age: 10.3±4.5 years old) were included in the study. Stool samples were collected for FCP analysis by ELISA method at the time of diagnosis and before the treatment period. Results: FCP values of the UC group were statistically higher than the control group. FCP values of the UC and control groups were 398.4 μg/gr stool (56.7-2450) and 19.4 μg/gr stool (2-81), respectively (p<0.005). FCP values of the patient group with mild activity index (n=8), and moderate-severe activity index (n=11) according to the Pediatric Ulcerative Colitis Activity Index were 267.6-μg/gr stool, and 435.2 μg/gr stool, respectively (r2: 0.40, p<0.05). There was not statistical difference between the FCP values of the patients with pancolitis (422.6 μg/gr stool) and with left-sided colitis, proctitis/sigmoiditis (371.7 μg/gr stool) (p>0.05). High CRP values (89.4%), elevation of erythrocyte sedimentation rate (84.2%), leukocytosis (73.6%), thrombocytosis (68.4%), anemia (89.4%), and hypoalbuminemia (52.6%) were found. Conclusions: FCP values of the UC patients were found to be statistically higher than the control group, and increase in FCP values has been observed with increasing disease activity. Therefore, we believe that the determination of FCP could be useful at the time of diagnosis and during follow-up of the patients with UC. © The Journal of Current Pediatrics, published by Galenos Publishing.

    (Comenius University, 2016) Tatli O.; Karaca Y.; Turkmen S.; Gulgen G.S.; Sahin A.; Eryigit U.; Fazli O.; Karaguzel E.; Mentese A.; Orem A.; Cansu A.; Turedi S.; Gunduz A.
    OBJECTIVE: We aimed to investigate the effect of mad honey on sexual performance. BACKGROUND: In traditional medicine in Turkey, mad honey is used to improve appetite, to heighten mental alertness, to reduce joint pain, to eliminate gastrointestinal system pains and to increase sexual performance. METHODS: In this experimental animal study eighteen Sprague Dawley male rats were randomized into three groups, a control group, a normal honey group and a mad honey group. Rats in the treatment groups were given a daily dose of 80 mg/kg normal honey or mad honey throughout the 30-day study period. Total testosterone, free testosterone, FSH, LH, estradiol, and progesterone levels were subsequently investigated from blood sera on day 30. RESULTS: Comparison of blood total testosterone levels among the groups revealed significantly higher levels in the mad honey group compared to the normal honey and control groups (p = 0.006, p = 0.00). Free testosterone levels were also significantly higher in the mad honey group than in the normal honey and control groups (p = 0.023, p = 0.01). No statistically significant differences were determined for other hormonal measurements. CONCLUSIONS: This study revealed a significant increase in both total and free testosterone levels in mad- -honey group.
