Reconstruction of partial ear defect to approximate the opposite normal ear is actually very difficult. Because the patterns of partial ear defect (site, shape and size of defect) are extremely variable, the operative method on each case should be changed. In an effort to overcome these problems, many reconstructive methods have been reported so far. We experienced 11 cases of partial ear defect from September, 1995 to August, 1996 and different reconstructive methods were applied In this study, the most common cause of partial ear defect was trauma (9 cases) and the most common site was middle part of ear helix. The defects were varying from 1x2 cm to 1.5x5 cm in size. The methods that has been used for reconstruction of ear defect include direct closure, helical chondrocutaneous advancement flap, Dieffenbach's method, retroauricular flap, tubed bipedicled flap and so on. We could get to know the merits and demerits of each method through this follow up study. So authors obtained the several basic conclusions about the merits and demerits of each method and standard of method selection in various patterns of ear defects. From analysis of the cases with review of literature, the our conclusions are as follows. 1. If the size of de(tract is small and the patient does not want to have two times of operation, direct closure can be done with good results. 2. If the defect exists on ear auricle confuted to helix and if there are no or small amount of associated cartilage defect, tubued bipedicled flap seems to be proper. 3. With the ear auricle defect confined to helix, especially helix of upper ear auricle, helical chondrocutaneous advancement flap can brought tile best result, though it has disadvantage of being decreased in its size 4. If there are extensive defect on ear auricle extending over scapha and antihelix, retroauricular flap can be done with good results. 5. In the ear auricle defect acompanying considerably large cartilage loss, Dieffenbach's method is thought to be proper.

This study was performed to compare the amount of blood flow from left and right side heart using Doppler echocardiography and Fick method. The pulmonary blood flow (Qp), aortic blood flow (Qs) and Qp/Qs ratio were noninvasively evaluated by two dimensional Doppler echocardiography in 10 patients with ventricular septal defect in children, aged 2 years to 15 years (mean+/-SD=7.1+/-4.9 years). Cardiac catheterization was performed within 2 days after examination of Doppler echocardiography in all patients. Systemic and pulmonary blood flow was calculated by using Fick principle, based on measured oxygen consumption and measured blood oxygen saturation. The Doppler frequency shift was analyzed by computer system combined with Meridian Echocardiography System. Comparison of Qp, Qs and Qp/Qs ratio obtained by invasive methods and by two-dimensional pulsed wave Doppler echocardiography showed a correlation of 0.679 in Qp, 0.710 in Qs and 0.639 in Qp/Qs ratio (p<0.05).

Serum levels of HDL-cholesterol, triglyceride and total cholesterol were measured in 107 normal Koreans and in 327 patients; 66 patients with hypertension, 34 patients with coronary heart disease, 45 patients with cerebral thrombosis, 18 patients with nephrotic syndrome, and 164 patients with diabetes mellitus. Patterns of serum lipoprotein fractions were also investigated by agarose gel electrophoresis in 41 normal Koreans and in 72 patients; 14 patients with hypertension, 10 patients with coronary heart disease, 19 patients with cerebral thrombosis, 7 patients with nephrotic syndrome, and 22 patients with diaebetes mellitus. The results are summarized as follows; 1. Mean values of serum HDL-cholesterol, triglyceride and cholesterol in normal Koreans were 52.2+/-12.4mg/100ml, 110.6+/-31.6mg/100ml and 175.3+/-21.4mg/100ml respectively. No significant difference in mean value of serum HDL-cholesterol was observed between Korean males and females. 2. In Korean females serum, HDL-cholesterol level showed peak values in the fifth decade, but no significant difference with aging was observed in Korean males. 3. Serum HDL-cholesterol levels were significantly decreased in patients with hypertension, coronary heart disease, cerebral thrombosis, and in male diabetic patients with complication. 4. Serum triglyceride levels were significantly increased in all the disease groups, and serum cholesterol levels were significantly increased in all the disease groups except cerebral thrombosis. 5. Mean values of alpha-lipoprotein, pre-beta-lipoprotein and beta-lipoprotein fraction ratios in normal Koreans were 28.9+/-7.5%, 14.9+/-4.9% and 56.2+/-8.1% respectively. 6. Seum alpha-lipoprotein fraction ratio was significantly decreased in relatively advanced hypertensive patients. Pre-beta-lipoprotein fraction ratio tends to be increased in patients with hypertension, cerebral thrombosis, nephrotic syndrome and in diabetic patients with complications, and beta-lipoprotein fraction ratio tends to be increased in patients with hypertension, coronary heart disease and nephrotic syndrome, but those were not statistically significant.

Dermal wound healing is a complex process that involved inflammation leading to re-epithelialization, granulation tissue, and tissue remodeling. Previous studies from our laboratory have shown that polysaccharides isolated from fungus, Phellinus gilvus (PG) have various anti-inflammatory activities. In present study, we have assessed the effect of polysaccharides from PG on the dermal wound healing of polysaccharides from PG in streptozotocin-induced diabetic rat model. Six of 6-mm circular wounds were created with biopsy punch on the 4th day after induction of diabetes. After 24 hours, each test substance was applied to the wound twice a day for next 5 days. Circular wounds treated with PG showed significantly reduced wound contraction and complete reepithelialization, as compared to wounds of non-treated (p < 0.05). These results show that polysaccharides isolated from PG enhanced wound repair in diabetic impaired healing, and could be developed as a wound healing agent in such clinical settings.
