For the last 20 years, several different techniques of fat injections have been developed. However, a standard technique of fat grafts has not yet been adopted for all practitioners. The purpose of this study was to evaluate the safety and long-term results of fat grafts using the modified Colman's technique. A total of 234 patients who underwent fat injections were retrospectively reviewed. The results were evaluated by patient satisfaction and photographs. The patient satisfaction was assessed using visual analogous scale(VAS), and photographs were evaluated by medical professionals. The fat was harvested using tumescent liposuction with a two hole Coleman harvesting cannula, and centrifuged at 3000rpm for 3 minutes. The refined fatty tissue was then transferred into a 1-ml syringe, and injected subcutaneously using 17-gauge cannula. The amount of fat tissue placed with each withdrawal of a cannula was 0.3~0.5mL. This technique showed good results with long-lasting volume consistency and few complications. The average value of VAS scored by patients was 8.7, and that by surgeons was 8.5, showing statistically no significant difference between the values evaluated by patients and surgeons. Author's fat injection procedure is a good choice for the correction of cosmetic defects and facial rejuvenation.

PURPOSE: To classify the cavernous sinus lesions, to describe their radiological findings, and to assess the usefulness of MR compared to CT. METHODS AND MATERIALS: Fourty-five patients with lesions involving the cavernous sinus proved by histological and/or clinical and imaging methods were studied retrospectively and classified into neoplastic, vascular, and inflammatory lesions. CT and MR findings were compared in 21 patients evaluated by both modalities simultaneously according to these 4 categories. RESULTS: Pitiutary macroadenoma was the most common cavernous sinus lesion(42%). Diffuse convex bulging of the lateral wall of cavernous sinus was the most frequent radiological finding(84%), and the others were encasement of the cavernous carotid artery(49%), remodelling of the surrounding bones(44%), and complete obliteration of Meckel's cave(38%), in descending order of frequency. Bulging of the lateral wall of cavernous sinus was equally well demonstrated on both modalities, but encasement or displacement of the cavernous carotid artery and complete or partial obliteration of Meckel's cave were much better delineated on MR than on CT with the ratio of 3.8:1 and 4.6: 1, respectively. Only bone changes were much better demonstrated on CTthan on MR with the ratio of 3.8: 1. CONCLUSION: MR issuperior to CTin demonstrating thecavernouscarotid artery encasement and obliteration of Meckel's cave, but CT is much better than MR in demonstrating bone changes.

BACKGROUND: Endotoxin stimulates nitric oxide synthase (NOS) and the free radical nitric oxide (NO) is produced by NOS, which vasodilates the smooth muscle of pulmonary vessels. Otherwise, endotoxemia stimulates the release of cyclooxygenase (COX) products, which may modify hypoxic pulmonary vasoconstriction (HPV). We also observed the effect of nonselective NOS inhibition by NG-nitro-L-arginine methyl ester (L-NAME) on receptor-mediated acetylcholine (Ach)/bradykinin (BK) induced vasoconstriction and receptor independent HPV in E.coli lipopolysaccharide (LPS) induced septic isolated rat lungs. METHODS: Four hours before surgical instrumentation for lung isolation, we administered saline (1 ml) to the control group (n = 15), E.coli LPS (20 mg/kg) to the LPS group (n = 14) and LPS (30 mg/kg) the nitric oxide synthase inhibitor, L-NAME (15 mg/kg) to the LPS + L-NAME group (n = 14), intraperitoneally. In 43 isolated rat lungs perfused with physiologic salt-albumin- blood mixture, angiotensin II 0.2 microgram was injected into the perfusion circuit, to confirm pulmonary vascular reactivity in each isolated lung. HPV responses were induced by three hypoxic challenges for 5 minutes separated by 5 minutes of ventilation with a normoxic gas mixture. We observed the pulmonary arterial pressure at each challenge, ten minutes after the last HPV, 0.01, 0.1, 1.0 microgram of Ach and 1, 3, 10 microgram of BK were injected. PAP and static lung compliance were measured. RESULTS: The baseline pulmonary artery pressure in the LPS group higher than in the controls and HPV in the LPS group was changed compared to the controls but in the LPS + L-NAME it was higher than in the controls. The administration of Ach 0.1, 1.0 microgram and BK 3, 10 microgram causedpulmonary vasoconstriction and the vasoconstrictions of BK were dosage-dependent. Lung stiffness in the LPS and LPS + L-NAME groups were higher than those of the controls. CONCLUSIONS: Vascular constriction of pulmonary vessels and increased lung stiffness by Ach and BK might be the result of the endothelial injury. But pulmonary vasoconstriction and stiffness by Ach and BK were similar in the LPS and LPS + L-NAME groups, showing that factors other rather than excessive NO production might be involved in endothelial injury.

A study was required to evaluate the prevalence of clonorchiasis among school children in the 7 differnet schools located near the Gumho basin and to determine the effectiveness of the anticlonorchis campaign conducted in that area. Surveys for Clonorchis sinensis and the worm burden in the same areas were compared for the period 1960-1970. Both surveys concentrated on children in grades 1-3 ranging from 6-11 years old. They were examined using primarily intradermal tests with Clonorchis antigen and followed by stool examinations. Stool examinations consisting of the formalin-ether sedimentation(Ritchie, 1948 ) and the Stoll egg-count techniques were performed in those cases which revealed positive and doubtful intradermal reactions. The overall prevalence rate for clonorchiasis was reduced from 13.4 per cent to 4.1 per cent. There was also a significant reduction in the worm burden, suggesting that no clonorchiasis will be found among chileren in the near future. In connection with this survey, the prevalence rate for intestinal helminths in 1960 was compared with 1970. The rate for Ascaris lumbricoides had decreased, while the rates for Trichuris trichiura and Trichostrongylus species had increased. No fluctuation in the rate of hookworm was observed during the past 10 years. Clearly, the present survey denotes a requirement for a combined procedure of health education and mass survey with intradermal testing. It has been found that these methods not only greatly reduce the prevalence of clonorchiasis but also is followed by the marked reductions of the worm burdens of the children examined.

Multiplex PCR for three STRs of same repetition unit [GATA]n, 4804LR[D12S66], 27H39LR[DYS19] and 4815LR[D12S67] loci, was constructed for forensic application DNA was extracted from 200 unrelated Koreans and amplified with a mixture of polyacrylamide gel electrophoresis, so called Amp-FLP procedure. Three loci could be co-amplified in a reaction with easy, and reaction condition was not so quite different from that of each locus. The PCR products of each locus could be separated bp, and 4815LR from 241 bp to 281 bp, so these alleles of each locus could be separated on a single electrophoresis. A total of six alleles was noted in 4804LR and heterozygosity was 0.5764. The allele 11 and allele 12 were frequently noted with the frequency of 0.6225 and 0.1775, respectively. Sequencing was done for 2 alleles, and the exact size of the alleles and the repetition unit were confirmed. Through statistical analysis forensic applicability of the STR 4804LR locus was confirmed. For 4815LR and heterozygosity was 0.5764. The allele 11 and llele 12 were frequently noted with the frequency of 0.6225 and 0.1775, respectively. Sequencing was done for 2 alleles, and the exact size of the alleles and the repetition unit were confirmed. Through statistical analysis forensic applicability of the STR 4804LR locus was confirmed. For 4815LR locus the amplification was successful, but the separation of the alleles on routine polyacrylamide gel was not successful. Some alleles was hardly separable, some alleles did not match the allelic ladder exactly, so the interallele was suspicious. On sequencing gel the electrophoresis pattern was quite different with that of routine polyacrylamide gel. A total of 11 allele was noted in 4815LR and heterozygosity was 0.765. For the routine use of the 4815LR locus, more meticulous method for the separation of the alleles such as using automatic DNA sequencer was necessary.

To know the amplification pattern according to relative concentration ratio in mixed samples, two STRloci, vwF locus and MBP locus and two VNTR loci, D1S80 locus and d17S5 locus were amplified in DNA with various concentration of two individuals were easily identified. But when the concentration of one person were lowered to 1/20-1/40 of the other's the intensity of product bands diminshed and hardly discernible. Also different amplification efficiency according to the template length was noted, especially in VNTR loci. Using automatic sequencer and RFLP scan program, the intensity OD of each PCR product band could be calculated, and this correlates the felative amplification efficiency of each allele. By using this we could construct quantitative PCR for the mixed samples. This could be used in practical case work for forensic purpose, and also be a valuable candidate for 'chimerism detection' in case of bone marrow transplatation.
