We present 20 medicolegal autopsies performed at the Department of Forensic medicine, Seoul National University Medical College during the year of 1996. In Korea Postmortem Invesigation (PI) system is not established and is needed greatly provide the basic considerations on PI system, we detailed the cases with impediments to be overcome. Among the 20 cases, 13cases were unusual deaths and 6 cases were natural. For unusual deaths, 7 were by mechanical injuries, four by asphyxia. Test for toxic stance was the most needed part to be solved.

PURPOSE: Direct injection of doxorubicin into the eyelids results in permanent loss of muscle fiber and it is considered an attractive nonsurgical method in essential blepharospasm therapy. However, necrosis of skin overlying orbicularis oculi muscle is the most serious side effect of this therapy. The purpose of this study is to determine the effect of doxorubicin delivered by osmotic pump which release doxorubicin slowly, and to evaluate the degree of overlying skin injury following chemical myectomy. METHODS: Thirty three rabbits were assigned to three groups according to the doxorubicin concentration. The first group received direct injections of 0.5 mg doxorubicin diluted in 0.1 ml of saline in the right lower eyelid. and osmotic pump was inserted into the left lower eyelid which contained 0.5 mg doxorubicin in 0.1 ml of saline. The second group received 1 mg doxorubicin and the third group received 2 mg doxorubicin. Eight weeks after injection, the eyelids were assessed for the degree of muscle fiber loss microscopically. For the evaluation of functional change of muscle, an EMG study was carried out. RESULTS: Skin necrosis developed in all rabbits except for one which received injection of 0.5 mg doxorubicin. Skin necrosis appeared earlier in the direct injection group. The duration of skin necrosis was shortened at lower concentrations(0.5 mg, 1.0 mg) with a pump delivery(P<0.05). But there was no statistical differences in the 2.0 mg concentration. The size of necrosis was much smaller in rabbits using pump delivery than those of direct injection group in high doxorubicn concentrations(1.0 mg, 2.0 mg)(P<0.05). The total size of muscle fiber was decreased after a doxorubicin injection. There was no statistical difference between the direct injection group and the pump group(P<0.05). The similar effect on the muscle was noted regardless of the slow release of the doxorubicin into the muscle. Light microscopic study demonstrated destructive change of muscle and it was replaced by connective tissues. Electron microscopic study showed destruction of micro-architecture of muscle fibers. Functionally, in EMG study, there was no motor activity in the injection area. But some motor unit potentials appeared in the periphery of skin necrosis site. CONCLUSIONS: These results suggest that the osmotic pump may be used as an effective adjuvant in preventing skin necrosis in blepharospasm treatment.

This treatise summarizes the medical facts about the persistent vegetative state(PVS) and the associated issues. In August 1998, the opinions of the 380 neurologists and the 1007 neurosurgeons are inquired about the diagnostic criteria of PVS, the degree and the withdrawal of treatment on PVS patients. The response rate is 18.8%. The diagnostic criteria of PVS is determined by the items approved above 5007o of responses. (1) no evidence of cerebral function and an inability to interact with visual, auditory stimuli and follow commands. (2) maintaining the respiratory function with spontaneous respiration and normal respiratory pattern. (3) spontaneous eye opening and eye ball movements without sustained tracking. (4) variably preserved brain stem reflexes. (5) presence of sleep-wake cycles. (6) (1)-(5) symptoms should be persist for 6 months after the development of vegetative state. (7) the diagnostic criteria of PVS should be applied more than 3 times during the minimum observation period. (8) this diagnostic criteria of PVS could be applied to adults over 7 ages. As to the degree of treatment, nasogastric tube feeding and air-way keeping through the tracheostomy are approved over 9007b. Also antibiotics can be used in infection. As to the withdrawal of treatment, do not resuscitate order of patient s family is accepted by 46.1% in an emergency condition like cardiac arrest. But discharge against medical advice by the patient s family is accepted by 73.107o in non-emergency condition. In the case of neonates, parents decision is more determinative than any other thing.

A 66-year-old female patient had a firm, non-tender, dome shaped mass on the scalp. The lesion had enlarged slowly for 2 years, and measured about 4 × 6 cm. The histologic finding of the skin biopsy specimen demonstrated an infiltration of immature plasma cells in the dermis, which express monoclonal cytoplasmic lambda light chain by immunohistochemical stainings, and staging work-up after the biopsy revealed no evidence of disease in other foci. The mass on the scalp was treated successfully by radiation therapy, with the diagnosis of primary cutaneous plasmacytoma.

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.

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.

The allele frequency and mutation rate in a Short Tandem Repeat locus, Y27 were studied in 247 unrelated Korean males using polymerase chain reaction followed by high-resolution polyacrylamide gel electrophoresis, a procedure called the amplification fragment length polymorphism technique. Six alleles were noted ranging from 190 bp to 210 bp. They existed as discrete bands with 4 bp discrepancy. Among which DY3(198 bp), DY4(202 bp) were common with the frequencies of 0.408, 0.356 respectively. Other alleles, DY1(190 bp, frequency 0.020), DY2(194 bp, frequency 0.121), DY5(206 bp, frequency 0.089), DY6(210 bp, frequency 0.004) were relatively uncommon. In a 78 subject father-son study with parenthood confirmed through other genetic studies, no case of mutation was noted. As the allele number was not as large as 6 and two alleles were dominant, the discrimination power in routine individual identification was thought to be low. But in selective cases such as father-son determination or sex determination, this locus could be a valuable genetic marker and we thought these results to be common for the Korean population. These results were also compared with that of other race.
