      다국어 초록 (Multilingual Abstract)

      The pericardial adhesions following the first open heart surgery are a major problem that can increase the morbidity and mortality by reoperation because of the danger of damaging the heart, great vessels, or grafts.
      The purpose of this study was to determine the effect of intra-pericardial infusion of 5% dextrose solution and heparin on the experimental pericardia! adhesions.
      The 15 white rabbits were divided into three treatment groups of 5 animals each: group 1 (control group), group 2 (5% dextrose group), and group 3 (heparin group).
      At 4 weeks, all animals were sacrificed and the pericardial adhesions were graded as follows: Ⅰ (none), Ⅱ (mild), Ⅲ (moderate), and Ⅳ (severe). Histological examination was performed on a subset of each group. The difference of adhesion between control and heparin group was evaluated by Chi-square analysis.
      The results were as follow:
      1. Pericardial adhesions developed in 80% of animals in group 1 and 2.
      2. Only 40% of animals in group 3 had mild to moderate pericardial adhesions. This was significantly different from the control group (P≤0.01).
      3. Histological examination showed that the pericardium with adhesion was thickened with fibrosis, while that without adhesion was thin, normal appearance.
      4. In group 3, there was no evidence of hemorrage or hemorrhagic tendency in the pericardium.
