OBJECTIVE: This study is proposed to examine the relationship between bone loss after hormone replacement therapy for one year and initial bone markers. METHODS: One hundred postmenopausal women were studied for one year. At first visit, measurements were made of bone mineral density(BMD) at the lumbar spine and femoral neck, and of serum osteocalcin and urine deoxypyridinoline. After hormone replacement therapy was done for one year, BMD was rechecked. RESULTS: Serum osteocalcin was correlated with the rate of bone change(r=0.150, 0.262) and urine deoxypyridinoline was weakly correlated(r=-0.003, 0.038). The changes of femoral BMD in women with higher concentration of osteocalcin and deoxypyridinoline were significant different from those in women with normal concentration. At the lumbar spine, no significant differences were showed. In women with higher concentration of osteocalcin, the incidence of subjects with increased spine BMD was increased up to around 71.1%, which showed not significant increase compared with normal concentration of osteocalcin. And the incidence of increased spine BMD in women with higher concentration of osteocalcin was marked increased compared with the incidence of normal concentration. The level of the osteocalcin with increased spine BMD was 11.5+/-6.6 ng/ml, and the level with decreased spine BMD was 9.2+/-4.7 ng/ml, respectively. And the level of the deoxypyridinoline was 7.2+/-4.2 pmol/ mol cr in women with increased spine BMD and 7.2+/-2.7 pmol/ mol cr in women with decreased spine BMD, which was not statistically different. The concentration of deoxypyridinoline with increased and decreased in BMD in spine and femur was not statistically different. but the concentration of osteocalcin was 12.2 +/-5.5 ng/ml in significantly increased in BMD and 8.5 +/-4.5ng/ml in significantly decreased in BMD, which was showed significant different. CONCLUSION: Present study indicates that the serum osteocalcin more reflcets bone turnover changes at the menopause than deoxypyridinoline, however, the clinical utility of measurements of osteocalcin only to response to therapy is uncertain.

To evaluate the clinical significance of anomalous pancreaticobiliary ductal union(PBDU), we analysed 11 cases(0.19%) of anomalous PBDU among 5675 cases performed ERCP from Jan. 1973 to Aug. 1992. According to the classification of Kimura et al., 4 cases were type 1(P-C union) and 7 cases type 2(C-P union). The length of common channel ranged from 1.5 cm to 3.1 cm(mean 1.9 cm). The common associated disease were choledochal cyst(7 cases), carcinoma of the gallbladder(5 cases) and biliary stone(3 cases). Four cases of carcinoma of the gallbladder were type 1. The incidence of anomalous PBDU was significantly higher in cases with carcinoma of the gallbladder(5 cases among 49 cases) than in case without carcinoma of the gallbladder(6 cases among 5626 cases). And the incidence of gallbladder carcinoma(45%) among the 11 cases of anomalous PBDU was significantly higher than that(0.78%) among those who did not have anomalous PBDU. In conclusion, the common associated diseases with the anomalous PBDU were choledochal cyst, carcinoma of the gallbladder and stone, and the anomalous PBDU may be risk factor in the development of carcinoma of the gllbladder.

The causes of jaundice in patients with hepatocellular carcinoma are usually attributed to the underlying liver diseases or extensive hepatic destruction by tumor. Obstructive jaundice by the intraluminal tumor fragment of intrahepatic and/or extrahepatic bile duct in hepatocellular carcinoma is exceedingly rare and usually diagnosed by operation or autopsy. Recently, we observed a patient in whom the fragment of tumor from the primary hepatocellular carclnoma obstructed the common hepatic duct, which was confirmed by peroral choledochoscopy. Using peroral choledochoscopy. we could see the mass located at the common hepatic duct and diagnose histologically by cytologic examination of aspirated material of common bile duct. We describe here this rare case with review the literature on primary hepatocellular carcinoma with jaundice caused by biliary obstruction.

Circling mouse (C57BL/6J-cir/cir) deleted the transmembrane inner ear (Tmie) gene is an animal model for human non-syndromic recessive deafness, DFNB6. In circling mouse, hair cells in the cochlea have degenerated and hair bundles have become irregularity as time goes on. Tmie protein carries out a function of the mechanoelectrical transduction channel in cochlear hair cells. Myosin7a (MYO7A) protein has key roles in development of the cochlear hair bundles as well as in the function of cochlear hair cells. To find whether Tmie protein interacts with MYO7A proteins in the cochlea postnatal developmental stage, we investigated expression of the MYO7A proteins in the cochlear hair cells of circling mice by western blot analysis and whole mount immunofluorescence at postnatal day 5 (P5). The expression of MYO7A showed statistically significant increase in the cochlea of C57BL/6J-+/cir and C57BL/6J-cir/cir mice than that of C57BL/6J-+/+ mice. The MYO7A intensity of the cochlear hair cells also increased in C57BL/6J-+/cir and C57BL/6J-cir/cir mice compared with those of C57BL/6J-+/+ mice. Taken together, the results indicate that Tmie protein may have an important role with MYO7A protein in the development and maintenance of the stereociliary bundles during postnatal developmental stage of the cochlea.

BACKGROUND: The current various case-finding instruments for detecting depression in Korea are too cucumbersome and time-consuming for routine use in primary care or student and soldier groups because of too many questions. We carried out this study in order to investigate the validity of the two-question case-finding instrument for detecting depression easily in the primary care or the mentioned groups. METHODS: We selected one boy high school in Seoul and 155 sophomer students answered the questionnaire by self-report. The questionnaire included two questions about depressed mood and anhedonia: (1) "During the past month, have you often been bothered by feeling down, depressed or hopeless?" (2) "During the past month, have you often been bothered by little interest or pleasure in doing things(e.g., studying, playing or talking with friends) ?". And then a resident of family medicine interviewed them and made a diagnosis for depression using the diagnostic criteria of DSM-IV. Simultaneously we compared the test characteristics of a two-question case-finding instrument with those of a previously validated Beck Depression Inventory as a currently world-wide used screening instrument for depression. RESULTS: The prevalence of major depression as determined by the interview was 6.6%(10 of 151). The two-question case finding instrument had a Cronbach's alpha of 0.663-internal consistency, a sensitivity of 100%, a specificity of 54.6%, a positive likelihood ratio of 2.20 and a negative predictive value of 1.00.(A "yes" answer to either of the two questions was considered a positive test.) And the BDI had a sensitivity of 90%, a specificity of 68.1%, a positive likelihood ratio of 3.63 and a negative predictive value of 0.99(cut-off point=15). Area under the ROC curves of the two-question case-finding instrument was 0.882, greater than that of the BDI, 0.834. CONCLUSIONS: The test characteristics of a two-question case-finding instrument were higher compared to those of BDI for major depression. Therefore, the two-question case-finding instrument is a useful measure for detecting depression and less time-consuming in primary care and certain groups.

Laboratory inbred mice are used widely and commonly in biomedical research, but inbred mice do not have a big enough gene pool for the research. In this study, genetic and morphometric analyses were performed to obtain data on the characteristics of a newly developing inbred strain (KWM/Hym) captured from Chuncheon, Korea. All of five Korean wild male mice have the zinc-finger Y (ZfY) gene. Also, all of 19 Korean wild mice used in this analysis have the AKV-type murine leukemia virus gene, indicating that Korean wild mice might be Mus musculus musculus. To identify the genetic polymorphism in KWM/Hym, SNP analysis was performed. In a comparison with 28 SNP markers, there was a considerable difference between KWM/Hym and several inbred strains. The homogeneity between KWM/Hym and the inbred strains was as follows: C57BL/6J (39.3%), BALB/c AJic (42.9%), and DBA/2J (50%). KWM/Hym is most similar to the PWK/PhJ inbred strain (96.4%) derived from wild mice (Czech Republic). To identify the morphometric characteristics of KWM/Hym, the external morphology was measured. The tail ratio of male and female was 79.60±3.09 and 73.55±6.14%, respectively. KWM/Hym has short and agouti-colored hairs and its belly is white with golden hair. Taking these results together, KWM/Hym, a newly developing inbred mouse originated from wild mouse, might be use as new genetic resources to overcome the limitations of the current laboratory mice.
