    The effects of caffeic acid phenethyl ester (CAPE) on spinal cord ischemia/reperfusion injury in rabbits
    (Oxford Univ Press Inc, 1999) Ilhan, A; Koltuksuz, U; Ozen, S; Uz, E; Ciralik, H; Akyol, O
    Objective: Oxygen-derived free radicals have been implicated in the pathogenesis of spinal cord neuronal injury after both trauma and ischemia-reperfusion. Caffeic acid phenethyl ester (CAPE), an active component of propolis extract, exhibits antioxidant properties. This experimental study was designed to determine the effect of CAFE on ischemia-reperfusion of spinal cord in rabbits. Methods: Forty-one New Zealand white rabbits were used in the study. The animals undergone aortic occlusion were divided into three groups each consisting of 11 rabbits: methylprednisolone (MP), CAFE, and control. CAFE 10 mu mol/kg, methyl prednisolone (MP) 30 mg/kg or similar dose saline were injected intraperitoneally before surgical intervention. Animals were subjected to 21 min of cross-clamp time. At the end of occlusion time, the clamps were removed and restoration of the blood flow was verified visually. Animals in sham group (n = 8) underwent a surgical procedure similar to the other groups but the aorta was not occluded. Neurological status was scored by assessment of hindlimb motor function deficit. Results: The scores in CAFE group was different from control groups at 48 h (3.91 +/- 0.5 vs. 2.91 +/- 0.7; P = 0.0013). Spinal cord specimens were obtained to determine the tissue levels of malondialdehyde, superoxide dismutase, catalase, and histological changes. Malondialdehyde levels in control group were increased significantly when compared to sham group (124.22 +/- 24.36 and 41.92 +/- 10.08 nmol/g wet tissue, P = 0.0003). MDA levels in the CAFE group were lower than MP group and differences between the two groups were statistically significant (56.77 +/- 15.265 and 107.74 +/- 19.31 nmol/g wet tissue, P = 0.0001), We did not observe additional tissue injury in CAFE group when compared to control group. SOD and CAT activities were not concordant in all the groups. Conclusions: These results suggest that CAFE may be an available agent to protect the spinal cord from ischemia-reperfusion injury.

    Experimental hydatid disease of the liver
    (Blackwell Science Ltd, 1997) Sahin, M; Aydin, A; Bulbuloglu, E; Ciralik, H
    Hydatid disease caused by Echinococcus granulosis is an endemic problem in many parts of the world and the liver is the most frequently involved organ. A suitable experimental model for hydatid disease of the liver, resembling naturally infected livers, is established in this study by injection of protoscolices via the mesenteric vein of the mice. This model can be used in assessment of the efficacy of various agents in treatment of hydatid disease of the liver.

    Giant vascular eccrine spiradenoma
    (Blackwell Science Ltd, 1998) Senol, M; Ozcan, A; Sasmaz, S; Ozen, S; Ciralik, H
    A 60-year-old man suffering from cardiac insufficiency consulted the Dermatology Department, Inonu University Turgut Ozal Medical Center, because of a bleeding tumor on his right hypochondrium. The tumor had begun as a small nodule approximately 5 years before, and had grown slowly with time. A small, superficial ulcer had appeared on the lesion approximately 6 months previously, and slight bleeding had occasionally occurred. The patient had no pain and no other complaint except bleeding. Dermatologic examination revealed a violaceous, ulcerated, and bleeding tumoral lesion below the mid-portion of the right costochondral line (Fig. 1). The tumor was a non-tender, hemispheric mass, approximately 3-4 cm in size, adherent to the epidermis, but movable on the underlying tissue. An incisional biopsy was performed with diagnoses of dermatofibrosarcoma protuberans and desmoid tumor. Histopathologic examination revealed prominent blood-filled vascular spaces (Fig. 2) and clearly delimited cords, showing two types of cell (Fig. 3). The vascular spaces contained a periodic acid-Schiff (PAS)-positive, granular, eosinophilic material. There was no malignant transformation. The lesion was totally excised and primarily sutured.
