Horizontal Mattress Suture Technique on Microvascular Anastomosis of rat (body weight: 200-250 gm) femoral artery was evaluated. The present study was conducted to compare the horizontal mattress suture with simple interrupted suture on the suture time, patency rate of the sutured vessels, and the histological changes of surgical site of the vessel wall during wound healing period. The mean suture time of the vessel wall with horizontal mattress suture technique was 15 min 49 sec ± 2.14, which is significantly shorter than that of simple interrupted suture technique. The patency rate of the sutured vessel in both groups was statistically not different each other till post-operative 3rd day but patency rate of horizontal mattress suture was higher than that of simple interrupted suture at post-operative 3rd week. The histological findings such as intimal noss, medial degeneration and intimal regeneration were similar in both groups.

The leukocyte alkaline phosphatase(LPA) activity in vaious stage of Jap. Encephalitis, which was admitted to Busan National University hospital from July to September in 1978, was investigated histochemically with the Tomonaga's naphthol AX-MX phosphate fast blue RR method. The author measured and compared with circulating leukocyte. Neutrophil and LAP activities. Patients were investigated the difference of sex and age, and compared to LAP activity and the prognosis of Jap. Encephalitis. The results were summerized as follows. 1. The Scores of LAP activity in acute of Jap. Encephalitis(3.22) were significantly higher than that of mid stage(2.48), recovery stage(2.37) and the control group(2.24). 2. The LAP activity was not influenced by sex and age. 3. The increas of DAP activity was found in the patients with leukocytosis charaterized by neutrophilia and it was relatively parallel with the increase of circulating neutrophil count. 4. In comparison to LAP activity and the prognosis in Jap. Encephalitis, ingeneral, LAP activity was relatively increases as the prognosis was become poor, but it was insignificant, statistically.

PURPOSE: To evaluate the usefulness of real-time ultrasound-guided biopsy as an aid in diagnosing pleural attached lung lesions. MATERIALS AND METHODS: Over a 2-year period (March 1992 through February 1994), 52 US-guided diagnostic biopsies were performed in 50 patients with peripheral lung lesions in contact with chest wall. 15 cases were performed with gun biospy and 37 cases with fine needles. Final diagnosis was confirmed by surgery and clinical follow-up. RESULTS: In 44 of 52 cases(84.6%), we obtained histologic or cytologic material by US-guided biopsy. Diagnostic accuracy and tissue type specific accuracy for malignancy were 83.9%(26/31) and 67.7% (21/31), respectively. Eighteen case% were reported to be benign and one of them was proven to be metastatic lesion. We could not find any complications such as hemoptysis or pneumothorax. CONCLUSION: Ultrasound-guided biopsy is a simple, safe and accurate diagnostic procedure for evaluation of peripheral lung lesion attached to the pleura.

In order to determine the distribution of each type of glaucoma in Korea, a retrospective clinical study was carried out on 206 glaucomatoils patients (295 eyes) who were followed from July 1982 to December 1985 in theClaucoma Clinic of the Department of Ophthalmology of Hanyang University Hospital. The distribution of glaucomatous patients was as follows; 34.0% primary open-angle glaucoma (POAG),32.5% secondary glaucoma,20.9% primary angle-closure glaucoma (PACG),7.3% ocular hypertension,3.9% congenital glaucoma, and 1.5% low tension glaucoma. In serondary glaucoma, glaucoma associated with uveitis occurred most frequently, and aphakic glaucoma, neovascular glaucoma, steroid-induced glaucoma, pigmentary glaucoma and exfoliative glauroma followed. The acute stage of PACG presented the highest initial IOP, 55.2+/-8.4mmHg, where as the initial IOP of POAG patients was 33.4+/-15.5 mmHg. Sixty-two per percent of POAG and 98% of PACG patients were over 40 years of age, and the mean age of the POAG and PACG patients was 43.1+/-16.3 and 61.6+/-9.5 years, respectively. There was no remarkable sex-difference associated with glaucoma, in PACG which showed an incidence of 79.1% in females. There was no significant difference in laterality between the right and left eyes with either glaucoma or ocular hypertension. Bilateral involvement of POAG and PACG during the follow-up period was 7l.4% and 32.6%, respectively.

The study was undertaken to evaluate the effect of major blood components on the CT number. The CT numbers according to the various levels of hematocrit, total protein and cholesterol were checked and analysed by the dilution of pack cell, plasma and 184 complete blood cell count samples under same scanning conditions. In case of normal protein and cholesterol level(33 samples), the CT number was increased about 5.5 hounsfield unit according to 10% increase of hematocrit level: and In case of normal hematocrit and cholesterol level(39 samles), the CT number was increased about 3.5 hounsfield unit according to 1gm% increase of protein level. CT number changes were not predictable according to the changes of cholesterol level(34 samples). From these results, we concluded that major blood components should be considered in the CT number analysis of tissue.

Retroperitoneal cystic lymphangioma is a rare benign tumor which had previously been difficult to diagnose preoperatively by conventional radiographic technique(1). Recent reports describe the computed tomographic and ultrasonographic findings in cystic lymphangioma(1,2). We report a case of retroperitoneal cystic lymphangioma, accurately diagnosed by lymphography, with computed tomographic findings and percutaneous drainage findings. To the best of out knowledge, this is the most aged case of retroperitoneal cystic lymphangioma of preoperatively diagnosed.

BACKGROUND: Malassezia species (spp.) are cutaneous opportunistic pathogens and associated with various dermatological diseases including seborrheic dermatitis, dandruff and atopic dermatitis. Almost all Malassezia spp. are obligatorily lipid-dependent, which might be caused by lack of the myristic acid synthesis. Recent genome analysis of M. restricta and M. globosa suggested that the absence of a gene encoding fatty acid synthesis might be compensated by abundant genes encoding hydrolases, which produce fatty acids, and that lipases and phospholipases may play a role in virulence of the fungus. OBJECTIVE: The current study aimed to investigate the contribution of lipases and phospholipases in virulence of the M. restricta as being the most frequently isolated Malassezia spp. from the human skin. METHODS: Swap samples of two different body sites of at least 18 patients with seborrheic dermatitis were obtained and in vivo expression of lipases and phospholipases of M. restricta was analyzed by the gene specific two-step nested RT-PCR. RESULTS: The results of the current study suggest that majority of the patients display expression of lipase RES_0242. CONCLUSION: These data imply a possible role of lipase in the host environment to produce free fatty acids for the fungus.
