4.Social Factors in Recruiting Physicians and Dentists.
Korean Journal of Preventive Medicine 1990;23(4):428-435
This study was designed to investigate whether recruitment of physicians and dentists has been restricted to a social network, such as familial or kinship groups. The data was collected through a self-administered questionnaire survey distributed to a sampling of general physicians, specialists (internists, surgeons, other specialists), and dentists in August 1990. The major findings are as follows: 1) Total number of respondents was 405; of these, general physicians made up 48.9%, internists 10.4%, surgeons 15.8%, other specialists 4.9%, and dentists 20.0%. 2) 38.5% of the respondents had physicians or dentists in their immediate family or were related in some way to one. Those from urban areas, whose parents were highly educated, and whose father was a professional had more physicians or dentists in their family or kinship. 3) Parents of 7.1% of the respondents, brothers or sisters of 10.1%, grand parents of 1.7%, uncles or aunts of 7.9%, and cousins of 22.0% were physicians or dentists. 4) The majority of physicians or dentists in familial or kinship network specialized in surgery, 32.3%, followed by internal medicine ; current worksites were noted as clinics by 30.8%, followed by general hospital, university hospital, and so on. The respondent's major discipline tended to follow familial or kinship example. Consequently, it was concluded that physicians and dentists have been recruited within restricted familial or kinship network.

5.Fibrin Glue for Bleeding after Total Knee Arthroplasty.
Journal of the Korean Knee Society 1998;10(2):148-153
Total knee arthroplasty has been associated with marked blood loss despite the use of a tourniquet and minimal postoperative suction drainage. The purpose of this study was to determine the effect and complication of topically applied fibrin glue(Tisseel) on blood loss. Fibrin glue was used to coat the operative site with a fibrin clot to determine the effect on postoperative blood loss. We reviewed 71 cemented total knee arthroplasties from June, 1996 to April, 1998. 71 cases of the total knee arthroplasty was composed of 31 case without fibrin glue(Group I), 12 cases with 5cc fibim glue(Group II) and 28 cases with 10cc fibrin glue(Group III). Hemoglobin and hematocrit were assayed before surgery and 1 day after surgery, and we compared the amount of the total blood loss, autotransfusion in each groups. The average amount of total blood loss is 1362cc(775-2150) in group I,1164cc(505-1670) in Group II, 772 cc(380-1410) in Group III. The average amount of autotransfusion is 72.7%(990cc) of total blood loss in group I, 91.4%(1064cc) in group II, 90%(650cc) in Group III, and Group II & III can autotransfuse above 90% of total blood loss. No significant difference was noted in preoperative and postoperative hemoglobin and hematocrit between each groups. Administration of fibrin glue gives a significant reduction of blood loss, enables autotransfusion about 90% of total blood loss, and provide the advantages of safety from transmission of viral diseases and from immunologic reaction. In conclusion, fibrin glue is a safe and effective hemostatic agent for bleeding control after cemented total knee arthroplasty.

This study examined burdens of primary family carcgivcrs of paticnto with cerebrovascular accidents (CVA) along with related factors. In addition, their needs for support group intervention were assessed to develop a support group to reduce the burdens of caregiving. Eighty-one primary family caregivers of patients with CVAs at a general hospital in Seoul participated in this study . The patients with CVAs aged from 26 to 83 years with mean age of 63 years. About 90% of the patients had some paralysis and 56.6% suffered speech problems. Fifty-eight percent of the primary family caregivers were spouses of the patients and 80.2% were women. Primary family caregivers' burdens were assessed by the Burden Scale originally devel oped by Zarit (1980) and Novak & Geust(1989) and modified by Jang (1995) for use in Korea. The instrument consists of six subscales time-dependent burden, developmental burden, physical burden, emotional burden, social burden, and financiaI burden. The results were as follows : 1. The average of burden score was 91.7, indicating moderate to severe level of burden. The time-dependent burden was scored highest followed by physical, developmental, social, financial, and emotional burdens. 2. of the characteristics of patients, age, gender, and severity of the disease were found to be associated with the level of burden. Of the characteristics of primary family caregivers, age and educational level were significantly related to the level of burden. Time of care since the CVA and the quality of relationship between a patient and a caregiver prior to the stroke were significant situational factors affecting the level of burden. 3. The need for support group intervention for the caregivero was very high (95.1%). The earcgivcrs of patients who had a CVA for the first time showed higher levels of need compared to those of patients who had a CVA more than once. The caregivers indicated a support group held once a month near home or hospital would be welcomed. In addition, they replied that a group composed of 9 to 10 caregivers and guided by health care professionals (e.g., physicians and nurses) would be most desirable. More than 85% of the earegivers identified the areas that they wanted intervention in as follows : knowledge, skills, and resources to care for a patient with a CVA. the counsel of health care professionals, share of their experiences with those who have similar situations, stress management skills, and methods to overcome emotional isolation due to the great responsibility for a patient. Given the results, support group is expected to be an effective way to reduce the burdens of primary family caregivers of patients with CVAs. As a follow up It is necessary to examine the effect of support group intervention on the patient's recovery and rehabilitation.

Translational and Clinical Pharmacology 2014;22(1):3-7
The cytochrome P450 (CYP) 3A subfamily is estimated to participate in the biotransformation of 50% of the currently prescribed drugs. Four members of the CYP3A subfamily have been identified in humans: CYP3A4, CYP3A5, CYP3A7, and CYP3A43. Initial data suggested that CYP3A5 accounts for only a small proportion of the total hepatic CYP3A in about 20% of samples, but it was later revealed that CYP3A5 represents more than 50% of the total CYP3A amount in some individuals. Several genetic variants have been described for the CYP3A5 gene, of which the CYP3A5*3 allele (gA6986G), the most common form and leading to the loss of CYP3A5 activity, has been extensively investigated in the aspect of pharmacokinetics and disease risk. This review summarized the molecular characteristics of the CYP3A5 gene, and discusses the association of the CYP3A5*3 polymorphism with disease risks such as cancer and hypertension, along with its role in the pharmacokinetics of CYP3A substrates.

Journal of Korean Society of Spine Surgery 1998;5(2):255-262
STUDY DESIGN: Thirteen patients with cervical interlocked facets dislocation in whom closed reduction by skull traction was failed were evaluated about the patterns of ruptured disc fragment. Objects : To evaluate the causes of failure at closed reduction, and the relation between ruptured discs and interlocked facets, and the treatment results through an anterior approach. SUMMARY OF LITERATURE REVIEW: In traumatic dislocation of the cervical facet joints, spinal cord or nerve roots injury associated with the ruptured disc fragment has been reported. However, there is few report evaluating the patterns of ruptured disc fragment as a cause of reduction failure. MATERIALS AND METHODS: Between 1988 and 1997, thirteen patients were treated by anterior fusion with plate after complete removal of the intervertebral disc through anterior approach and reduction of interlocked facets by O1iveira method. They have been followed for an average of 36 months(range : 12-96 months). The interlocking was bilateral in seven cases and unilateral in six cases. We assessed the types of ruptured disc fragment by preoperative MRI and CT and the clinical and radiological results. RESULTS: Ruptured disc fragment was found in all thirteen patients with interlocked facets dislocation. The patterns of ruptured discs were within the uncovertebral joints in 5 cases, posterioly under the posterior longitudinal ligament in 3 cases, anteriorly under intact anterior longitudinal ligament in 3 cases and combined under the anterior and posterior longitudinal ligament in 2 cases. The displacement of ruptured disc fragment were seemed to be the cause of failure in closed reduction. CONCLUSIONS: Intervertebral disc injury should be evaluated carefully with MRI and CT in the lower cervical interlocked facet dislocations before trial of reduction or decision makings of treatment.

Korean Journal of Fertility and Sterility 1998;25(1):9-16
This study was performed to investigate the stimulating effect on oocyte maturation and cumulus cell expansion in TC199 media by human cord serum (HCS) supplementation. Immature mouse oocyte cumulus complexes (OCCs) were cultured in TC199 media supplemented with bovine serum albumin (BSA), HCS and human chorionic gonadotropin (hCG) instead of luteinizing hormone (LH) respectively, and the expression of cumulus expansion and oocyte maturation were observed. After 4hr and 24hr culture with or without OCCs, media containing 0.4% BSA, 10% HCS and 10 lU hCG respectively were collected and analyzed for changing concentrations of estradiol (E2), progesterone(P4), testosterone(T), and PGF2. There were no elevation of E2, T, and PGF2 by OCCs culture, but minute elevation of P4 level by 24hr OCCs culture in hCG supplementation (p=0.048). The stimulating pattern of cumulus expansion of OCCs by HCS and hCG supplementation was similar to our previously report using Ham's F-10 media, however oocyte maturation rates after 24hr OCCs culture in all media were increased by 20~30% compared to Ham's F-10 media. These results suggest that LH in HCS induce cumulus expansion probably by P4 secretion of OCCs, and TC199 is efficient media for immature mouse oocyte maturation.
