OBJECTIVE: Estrogen is a major regulator/modulator of bone metabolism, and bone loss in estrogen deficiency is associated with increased bone turnover, But the mechanism for estrogen action on bone metabolism is still unknown. Recent studies have suggested that the increase in bone loss induced by estrogen deficiency is mediated by increased paracrine production of bone resorbing cytokines. Among cytokines, 1nterleukin-6(IL-6) is released from osteoblasts in estrogen deficiency and increases bone resorption by stimulation of osteoclastic activities and recruitment. Thus we performed this study to evaluate the effect of ovariectomies on bone mineral density and IL-6 in cultured monocytes of peripheral blood and bone marrow. METHODS: The experimental animals were 13 female Sprague-Dawley rats that were 8 weeks of age and weighed an average of 188.5 gram at the beginning of the study. Bilateral ovariectomies were performed in all rats from a ventral approach. Bone mineral density(BMD) of the total body, spine and level of IL-6 of cultured monocytes of peripheral blood and bone marrow were measured before and 8 weeks after ovariectomy. RESULTS: 1) BMD of total body and spine were lower after ovariectomy(0.257+/-0.069g/cm2, 0,208+/-0.005g/cm2) than before ovariectomy (0.276+/-0.005g/cm2, 0.229+/-0.011g/cm2), respectively (P<0.01). 2) Although IL-6 level of cultured monocytes in peripheral blood tended to be higher after ovariectomy than before ovariectomy, this difference was not statistically significant (P>0.05). 3) IL-6 level of cultured monocytes in bone marrow was higher after ovariectomy(82.78+/-4.99pg/ml) than before ovariectomy(48.85+/-2.42pg/ml)(P<0.05). CONCLUSION: It is possible that increased production of IL-6 in estrogen deficiency induced by ovariectomy occurs in the local environment of bone or bone marrow rather than in the pheripheral blood and stimulates bone resorption.

To observed whether the specific IgG antibody test using ELISA was useful in diagnosis of presently ill patients of paragonimiasis, a total of 95 sera were tested. The sera were collected from 21 egg positive cases, 8 from positive reactors of intradermal test, 7 from Clonorchis infected, 9 from other parasitic diseases and 50 from apparently non-infected cases. By the result, the sensitivity of the test was 86% and the specificity was 100%. There were no cross reactions between Paragonimus antigen and other parastic infections. Specific IgG antibody test by micro-ELISA was concluded to be useful for mass screening of the presently ill paragonimiasis in the field.

PURPOSE: To cmpare the clinical results of complex tibial plateau fractures treated by hybrid external fixation and dual plate fixation. MATERIALS AND METHODS: We studied forty patients with Schatzker type V and VI fractures respectively and selected twenty seven patients who were followed at least one year between January 2000 and December 2005. We evaluated the clinical results in which fourteen fractures with hybrid external fixation were compared with thirteen fractures with dual plate fixation. The clinical results were evaluated according to Knee Society Clinical Rating System and the statistical analysis was performed by Student t-test. RESULTS: There were no significant differences in terms of bone union time (average union time: dual plate fixation 13.8 weeks, hybrid external fixation 14.2 weeks). The quality of osseous reduction was superior in the fractures with dual plate fixation than those with hybrid external fixation. There were significant differences in functional score (average functional score: dual plate fixation 73, hybrid external fixation 62), but not in average knee score. CONCLUSION: The hybrid external fixation can be a useful modality for treatment of complex proximal tibial plateau fractures. But the good quality of the fracture reduction by dual plate fixation may be a indicator for favorable prognosis for satisfactory knee function.

This series represents 128 cases of acute gonococcal urethritis treated with doxycycline at the Seoul Red Cross Hospital from the 1st. May to.5th, Oct., 1969. Results of this treatment were divided in three groups: Group I ; Single dose of doxycycline, 300 mg. was administered for this group. 36 cases fall into this category. Cure rate for this group was 36%. Group II; Doxycycline, 200mg. was given on the 1st treatment day and daily dose of 100 mg. for 4 ensuing days. 42 cases were included to this group. Cure rate was 72%. Group III Daily dose of 200 mg. was administered for the remainders, 50 cases for 5 consecutive days. Cure rate was 91%. It was concluded that 200 mg. of doxycycline daily for 5 days dose regime can be recommended for the treatment of acute gonococcal urethritis, especially in cases allergic to penicillin or in which penicillin treatment fails. No anaphylactic shock or some other undesirable side reaction in administering this drug was experienced.

PURPOSE: recent studies have reported that the expression of Drg-1 is up-regulated by androgen. It has been suggested that Drg-1 gene be used as a molecular marker for prostate cancer therapies like PSA. To de termine the role of Drg-1 gene as a molecular marker during intermittent androgen deprivation(IAD) therapy, we investigated the expression of Drg-1 and compared it with PSA expression in human prostate cancer cell lines treated with dihydrotestosterone (DHT) continuously or intermittently. MATERIALS AND METHODS: Two prostate cancer cells having different status of androgen receptor [LNCaP (androgen dependent) and PC-3 (androgen independent)] were used in this study. To know the change in PSA and Drg-1 expression after DHT treatment the cells were cultured in steroid-free RPMI media for 24 hours. 10(-7) and 10(-8)M of DHT and 10(-7)M bicalutimide was added into the cells and then cultured for 72 hours. And we established in vitro IAD model using LNCaP cells. Northern analyses were performed to determine the expression level of both PSA and Drg-1genes. Also, western analyses were performed to determine the protein level of proliferating cellular nuclear antigen and androgen receptor. RESULTS: Transcripts of Drg-1 were detected in both LNCaP and PC-3 cells but PSA was not expressed in PC-3 cells. The expression of Drg-1gene in LNCaP cells was up-regulated by 10(-8)M of DHT like PSA gene and down-regulated by 10(-7)M bicalutamide. In the treatment of intermittent androgen deprivation, the expression pattern of Drg-1was similar to that of PSA. However, up-regulation of PSA was detected earlier than of Drg-1. CONCLUSIONS: Based on observation, Drg-1 was up-regulated by androgen and down-regulated by anti-androgen. This suggests that Drg-1gene is useful for determining the androgen independency of prostate cancer during IAD.

BACKGROUND: Respiratory depression with high dose of propofol during induction is one of the major complications. We studied the effects of midazolam as premedicant on frequency and duration of apnea and frequency of loss of consciousness in relation to single dose of propofol. METHODS: We selected 194 adult patients who had clear consciousness and no depression of respiration. We allocated patients randomly to control group and midazolam group. In midazolam group, we injected 0.06mg/kg of midazolam intravenously 10min before induction, and in control group, we did nothing. Under mask oxygenation with 100% oxygen, we administered a bolus of propofol (1, 1.5, 2 mg/kg to subgroup 1, 2, 3 respectively) intravenously. The change of respiration and loss of consciousness were observed. RESULTS: The frequency and duration of apnea increased with the dose of propofol in both control and midazolam group. But there were no difference between groups except frequency of apnea with 1.5 mg/kg of propofol. In control group, frequency of loss of consciousness increased with the increasing dose of propofol. But in midazolam group, nearly all the patients was slept without difference by the dose. CONCLUSIONS: Premedication with midazolam reduce the sleeping dose of propofol to induce anesthesia, so the frequency and duration of apnea which is caused by high dose of propofol can be decreased.

There is a great variety of abdominal calcifictions of varying etiology. Among them, calcification in gastriccarcinoma is rare. To the best of our knowledge, there has been no previous report of calcifying mucinousadenocarcinoma of the stomach in Korea. In the present communication, we report two cases of this rare tumor. Thefirst case was 27 years old female who had anorexia and palpable mass in the epigastrium. By palpation, a firmnon-tender large mass ws felt in the epigastrium. A plain abdominal film showed numerous pnuctate calcificationsin the left upper quadrant. Film from an upper G-I series demonstrated findings of advanced gastric carcinoma withmultiple punctate calcifications involving the antrum and body. Gastroscopic biopsy proved the lesion to bemucinous adenocarcioma(signet ring cell type). The second case was 38 years old female who compained of nausea,vomiting and weight loss. On physical examination, she appeared normal. Routine laboratory tests were withinnormal limits. A plain abdominal film revealed stippled calcifications in the left upper quadrant medial to thesplenic shadow. The film from an upper G-I series showed a mass in the fundus and upper body of stomach withmultiple stippled calcifications along the lesser curvature. Subtotal gastrectomy was perfomred and the pathologicfindings was calcifying mucinous adenocarcinoma(signet ring cell type).
