    (Canadian Soc Clinical Investigation, 2010) Turtay, Muhammet G.; Firat, Cemal; Samdanci, Emine; Oguzturk, Hakan; Erbatur, Serkan; Colak, Cemil
    Purpose: Montelukast, a selective cysteinyl leukotriene D(4)-receptor antagonist, is used in the treatment of asthma. In a rat model, our aim was to investigate the effects of montelukast, alone or in combination with topical antibiotics, on local burn wound healing. Methods: Rats were randomly allocated to four groups after local burn development: Group 1; rats were left to secondary healing without treatment, Group 2; a dose of 10 mg/ kg montelukast was given by gastric gavage once a day for 10 days, Group 3; rats were treated with topical pomade (bacitracin neomycin sulphate), and Group 4; rats were treat with a combination of topical antibiotic and montelukast (10 mg/kg were given by gastric gavage once a day for 10 days). Skin biopsies were taken on days 3, 10, 14, and 20 relative to burn induction. Results: Reepithelialization in the pomade and montelukast+pomade groups on the 10(th) day was significantly greater, in comparison with control and montelukast groups (p<0.05). For the montelukast group, edema (on the 14(th) day) and angiogenesis, fibroblast proliferation, edema and macrophage infiltration (on the 20(th) day) were statistically improved in comparison with the control group (p<0.05). For the montelukast+pomade group, angiogenesis, fibroblast proliferation and macrophage infiltration (on the 10th day), and angiogenesis, fibroblast proliferation, edema and macrophage infiltration (on the 14th and 20th days) were statistically improved in comparison with the control group (p<0.05). Conclusion: In conclusion, montelukast was effective on burn wound healing. Moreover, the effect was amplified when combined with topical antibiotics applied in the early stage of burn wound healing.

    Histopathological effects of fibrin glue on penile fracture in a rat model
    (Canadian Soc Clinical Investigation, 2011) Tasdemir, Cemal; Samdanci, Emine T.; Turtay, Muhammet G.; Firat, Cemal; Oguzturk, Hakan; Ozdemir, Hulya
    Purpose: To evaluate both histopathological effects and potential clinical application of fibrin glue on the penile cavernosal tissue. Methods: Experimental penile fracture was formed by incising from the proximal dorsal side of the penis in 32 Wistar Albino rats. The rats were randomly assigned to four main groups of eight animals each. In the control group, the incision was not repaired and it was left to secondary healing. In the primary repair group, the incision was primarily repaired. In the fibrin glue group, glue was applied only to the incision. In the final group, fibrin glue was applied to the incision following primary repair. Three weeks later, penectomy tissue was examined histopathologically. Results: When the control group was compared with primary repair+fibrin glue group, the differences in cavernous tissue healing with fibrosis and inflammation were statistically significant (p = 0.04 and 0.01, respectively). The primary repair+fibrin glue group, showed the best cavernous healing with fibrosis observed in only one rat.. There was no significant difference between the control group and the other groups according to cavernous tissue healing with fibrosis and inflammation (p = 0.11 and 0.12). Hyperemia was observed in the all groups of rats. Conclusions: Fibrin glue can be used in cavernoseal surgeries due to its adhesive and potentially anti-inflammatory features.
