    (Medical Science and Technology, 2009) Rahman, Ali; Çolak, Mehmet Cengiz; Üstünel, Latif; Koç, Mustafa; Kocakoç, Ercan; Çolak, Cemil
    Background: This study aimed at evaluating the benefits of the traditional management of acute deep vein thrombosis (DVT), subcutaneous (sc) administration of low-molecular-weight heparin (LMWH) one dose a day and bed rest, and LMWH with compression stocking and early ambulation compared with LMWH with pneumatic compression (PC) in patients with DVT. Material and Method: Forty-eight consecutive patients with DVT were separated evenly into four groups. Group A received intravenous unfractionated heparin, group B received sc injection of enoxaparin sodium and bed rest, group C received sc injection of enoxaparin sodium and thigh-length compression stockings, and group D received sc injection of enoxaparin sodium and PC for periods of up to 7 days. Results: Comparing days 0 and 7, significant differences were determined in each group regarding differences in circumference of the two legs at the thigh and calf levels and the visual analogue scale (VAS) of pain, and in groups B, C, and D regarding the Lowenberg test for diseased and healthy legs (p<0.001). Between days 0 and 7, significant differences were found in the superficial femoral artery, superficial femoral vein, femoral vein, and the popliteal vein within groups A and D (p<0.05). Conclusions: Traditional management, sc administration of low-molecular-weight heparin, and pneumatic compression of patients with DVT led to a faster reduction of leg swelling and pain and to increased volume flow through the deep veins of the legs.

    Immunohistochemical evaluation of the effects of nebivolol on intimal hyperplasia following endothelial injury
    (Tubitak Scientific & Technological Research Council Turkey, 2011) Akar, Ilker; Rahman, Ali; Colak, M. Cengiz; Ustundag, Bilal; Ozercan, Ibrahim Hanifi; Uysal, Ayhan
    Aim: Intimal hyperplasia is a vascular remodeling process. It is a clinical problem that forms in the vascular wall as a result of smooth muscle cell migration, proliferation, and extracellular matrix accumulation. In this study we examined the immunohistochemical evaluation of the effects of nebivolol on intimal hyperplasia in damaged endothelial tissue. Materials and methods: The study was conducted using 21 rabbits equally divided into 3 groups: control, solvent, and nebivolol. The rabbits in the control group only underwent balloon injury of the abdominal aorta. The rabbits in the solvent group and nebivolol group underwent balloon injury and were treated with solvent and nebivolol intraperitoneally during the study. At the end of the study, the abdominal aortas were harvested. The intimal and medial areas were measured and the intima/media ratios were calculated. Tissue nitric oxide levels were determined and immunohistochemical findings were evaluated. Results: Statistically there were no differences between the control and solvent groups with respect to the intimal and medial areas, intima/media ratios, or the tissue nitric oxide (NO) levels. The neointimal thickening was significantly less in the nebivolol group than in the control and solvent groups (P < 0.001). Intima/media ratio was decreased in the nebivolol group (P < 0.001). Tissue nitric oxide levels were greater in the nebivolol group than in the control and solvent groups (P < 0.01). Immunohistochemical data in the nebivolol group were significantly lower as compared with the other groups (P < 0.05). Conclusion: Nebivolol may be a useful agent in early restenosis after vascular reconstructive procedures.
