1.Variation of nuclear and mitochondrial DNAs in Korean and Chinese isolates of Clonorchis sinensis.
The Korean Journal of Parasitology 2004;42(3):145-148
We compared the DNA sequence difference of isolates of Clonorchis sinensis from one Korean (Kimhae) and two Chinese areas (Guangxi and Shenyang). The sequences of nuclear rDNA (18S, internal transcribed spacer 1 and 2: ITS1 and ITS2) and mitochondrial DNA (cytochrome c oxidase subunit 1: cox1) were compared. A very few intraspecific nucleotide substitution of the 18S, ITS1, ITS2 and cox1 was found among three isolates of C. sinensis and a few nucleotide insertion and deletion of ITS1 were detected. The 18S, ITS1, ITS2 and cox1 sequences were highly conserved among three isolates. These findings indicated that the Korean and two Chinese isolates are similar at the DNA sequence level.

To determine the molecular phylogenic location of Plagiorchis muris, 28S D1 ribosomal DNA (rDNA) and mitochondrial cytochrome C oxidase subunit I (mtCOI) were sequenced and compared with other trematodes in the family Plagiorchiidae. The 28S D1 tree of P. muris was found to be closely related to those of P. elegans and other Plagiorchis species. And, the mtCOI tree also showed that P. muris is in a separate clade with genus Glypthelmins. These results support a phylogenic relationship between members of the Plagiorchiidae, as suggested by morphologic features.

Ninety cases of meniscus injury were treated by arthroscopic meniscetomy between March, 1988 and March, 1992. Eighty four cases were treated by arthroscopic partial, 5 cases by subtotal, and 1 case by total meniscectomy. All cases were followed up for more than 1 year. The results were as follows. 1. The ratio of male to female was 57 to 31, and that of right to left was 52 to 38. 2. There were 41 cases of medial meniscus and 49 cases of lateral meniscus. Longitudinal tears were 35 cases (39%), oblique tears were 20 cases (22%), horizontal tears were 15 cases (17%), and radial tears were 9 cases (10%). There was no difference in the shape of tear between medial and lateral meniscus. 4. The most common associated injury was anterior cruciate ligament tear. 5. The Tapper and Hoover scale was used to record the clinical results, and satisfatory results (exellent and good)were in 86% of cases.

The 4,725 cattle in the enzootic region, 6 counties of southern Korea, were surveyed for besnoitiosis epidemiologically by examining the scleral conjunctiva for the cysts and the following results were obtained. The survey showed that 285 cattle, representing 6 per cent of a total of 4,725 cattle examined had S.C. cysts. Only 49 (14 per cent) of them showed clinical sclerodermatitis and the ratio between clinical and inapparent cases was 1:5.8. On age distribution of the S.C. positive cases the highest incidence(10-12 per cent) was seen in amimals that were from 5 to 8 years of age, but clinically apparent cases occurred much more in younger age of animal. In local incidence of S.C. cysts positive cases the prevalence was higher in the secluded districts such as Koheung and Sancheoung counties(9 per cent).

7.Cadaveric Kidney Transplantation .
Korean Journal of Anesthesiology 1979;12(2):157-162
Recently, with the help of medical development which is able artificially to control respiration, circulation, nutrition and excretion, human beings may still survive in spite of brain death. We have had experience with the first case of cadaveric kidney transplantation in Korea. Because the prognosis of kidney transplantation is relatively good in comparison to the five-year survival rate of cancer patients and because postoperative rehabilitation is fair, nowadays kidney transplantation is popular. With the limitations of confluent acceptance and supplimental functioning together of the living kidney, cadaveric kidney transplantation has been preferred, although several problems still exist. We have used the conventional method to maintain the cadaver donor's life after clarification of death. As soon as brain death was confirmed on EEG monitoring, then an artificial respirator was applied to the tracheotomy site, adequate urinary excretion was maintained and infection prevented. At the same time, the HL-A(human lymphocyte-antigen) compatibility test and ABO blood matching had to be performed before anesthesia. The patient's intraoperative and postoperative course was satisfactory and he now has no problems of physical or social activity. However cadaveric kidney transplantation is in the early phase in Korea, and therefore further improvement is needed, and several problems should be solved. We hope many cadaveric kidney transplantations will be performed.

8.Revascularization for Patients with Idiopathic Thrombocytopenic Purpura and Coronary Artery Disease.
Korean Circulation Journal 2014;44(4):264-267
Idiopathic thrombocytopenic purpura (ITP) is an autoimmune disorder with a low platelet count characterized by premature platelet destruction and suppression of platelet production mediated by autoantibodies, which may predispose to bleeding. Although the prevalence of coronary artery disease (CAD) in ITP seems to be rare, their co-occurrence is not unusual. Patients with ITP have increased risks for thrombosis and atherosclerosis associated with hemostatic factors, endothelial damage, and the negative effects of steroid and immunoglobulin therapies. Thus, the coexistence of ITP and CAD presents complex problems requiring a balance between hemorrhagic risk and prevention of thrombosis. Here, the authors present two patients with ITP, who were revascularized in different ways for CAD. Although the optimal management of thrombocytopenic patients with CAD is uncertain, individualized treatment modalities can be useful in patients with ITP and CAD.

Biofeedback is the treatment of choice for functional defecation disorders such as idiopathic chronic constipation and neurogenic fecal incontinence. The pre-existing biofeedback systems have many disadvantages. The aims of current project are, first, to develop the biofeedback system into the application software in the Windows environment, and, second, to assess the possibility of clinical usage for patients with functional defecation disorders. The hardware and software of the BASCO (Biofeedback Anal Sphincter Control) system were based on the signal measurement and signal processing of anal sphincter EMG (Electromyography). BASCO system was applied to 5 normal healthy controls and 20 patients with functional defecation disorders. Patients group was categorized as constipation group (N1=15) and incontinence group (N2=5). With use of current system, EMG-based biofeedback therapy was performed, and the outcome was analysed. Anal EMG signal data was processed by the software, and displayed in the monitor of personal computer. The software of EMG-display and database management were adequately operated. In N1 group, a paradoxical elevation or equalized activity of anal EMG pattern was shown in the simulated defecation. In N2 group, low electrical activity was shown. These findings were used for the EMG-based biofeedback therapy as a pilot study. The clinical symptoms were improved in 12 of N1 group and 3 of N2 group in the period of 3.7 (range, 1~12) months follow-up. In Conclusion, newly-developed BASCO system was adequately operated in the volunteer and patients groups. The multi-tasking and multi-processing functions were adequately shown in the real time. Current results could be used for clinical appraisal. Specifically, this system could be used for the practical application of biofeedback therapy in the patients with chronic constipation or fecal incontinence.

Korean Journal of Anesthesiology 1980;13(3):244-249
Patients vary markedly in their responses to d-tubocurarine chloride. Despite an attempt to diminish the variation in responses to relaxants by standardizing experimental techniques, anesthetic concentration kept constant, acid-base status kept constant, premedication omitted, dosage calculated in terms of mg/sq meter body surface, the marked variation was found to persist. The dose related neuromuscular blocking effect of d-tubocurarine chloride was investigated using a rabbit common peroneal nerve anterior tibial muscle preparation. All experimental rabbits tracheas were intubated through tracheostomy under general anesthesia with Nembutal 40 mg/kg intravenously. Reapiration was controlled by a Harvard animal respirator. The body temperature was kept at 35-37 degrees C by a thermoblanket. The degree of neuromuscular block following intravenous d-tubocurarine chloride was measured by single twitch response. The common peroneal nerve was stimulated supramaximally using a square waves of 0. 2 msec duration at a frequency of 0.1 Hz, and each stimulus was repeated once every 10 seconds. The ratio of the twitch height was calculated. The results were as follows: 1) No neuromuscular blocking effect was observed with 0.1 mg/kg of intravenous d-tubocu- rarine chloride. 2) 100% of neuromuscular blocking effect was observed with more than 1mg/kg of intravenous d-tubocurarine chloride. This is 5 to 10 times higher than the human dose. 3) Dose related prolonged neuromuscular blocking effect was observed from d-tubocurarine chloride in rabbits.
