OBJECTIVE: The purpose of this study was to evaluate the effect of polycystic ovarian follicular fluid on sperm motility in human in vitro fertilization (IVF). METHODS: From May, 1998 to July, 1999, 55 patients who complained of infertility were involved in this study. We obtained ovarian follicular fluids form the patients by ultrasono-guided aspiration. Subjects were divided into two groups. 20 patients who had polycystic ovarian disease were belong to study group, and 25 patients who had normal ovarian follicular fluid were belong to control group. The follicular fluid dilution was done with Ham's fluid as 10%, 20%, 50%, 100%. The sperm motility was analyzed by CASA at 6hr and 12hr after incubation in follicular fluids. RESULTS: The levels of average path velocity (VAP) in all concentration fluid didn't show significant difference between study and control group. The other parameters including curvilinear velocity (VCL), amplitude of lateral head displacement (ALH), and linerity (LIN) were didn't show any significant difference between both groups. CONCLUSION: PCOD fluid had seemed to have an adverse effect on the sperm biological function. But, this study showed that PCOD fluid had no different effect on sperm motility with normal follicular fluid.

This study was carried out from 1993 to 1994 in the small industries in Incheon. The objectives of this study was in order to estimate the quitting rate, to identify its relating factors and to propose effective quitting management policy in the small industries. The results were as follows; 1. The quitting rate of 266 study workers was 42.1%(l12 workers). 2. Age, working duration, position, marital status were significant difference between the quitting group and the non-quitting group. 10 the quitting group, mean age was young, working duration was short, general employees and unmarried workers were many compared with the non-quitting group. 3. In the industry characteristics, total assets, total sales, sales per person, establishment duration and occupational health and safety status were significant difference between the quitting group and the non-quitting group. In the quitting group, total assets, total sales and sales per person were little, establishment duration of company was short and occupational health and safety status were poor compared with the non-quitting group. 4. In the quitting group, worker's response to employer's disposal about health and safety was more passive and the relation to employer with employee was significantly poor compared with the non-quitting group. 5. Multiple logistic regression analysis of quitting against family income per person, working duration, relation to employer with employee, occupational health and safety status in industry, worker`s response to employer's disposal about health and safety and sales per person was done. Working duration, occupational health and safety status, worker`s response to empolyer's disposal about health and safety were significant eiplainatory variables for quitting. Above results showed that the quitting rate was high and it was significant difference between the quitting group and non -quitting group according to characteristics of workers and of industries. Especially, it suggested that working duration, occupational health and safety status and worker's response to employers disposal about health and safety were significant quitting factor. Therefore, it should be reflected in the quitting management and the policy of steady employment.

BACKGROUND: Chicken pox and herpes zoster are caused by the varicella-zoster virus(VZV). To investigate the epiderniologial relationship between clinical isolates of VZV, it is essential to distinguish different isolate. OBJECTIVE: This study was conducted to classify the VZV strains according to R5 tandem direct reiterations(TDR) copy numbers and Pst I endonuclease cleavage site mutation, and to analyze the distribution pattern of VZV strains isolated in Korea. METHODS: Strains of VZV were isolated from 61 patients with herpes zoster who had not been immunized with a live vaccine of VZV. Copy numbers of R5 TDR which was located in variable region IV were measured by PCR. The presence of a Pst I cleavage site in a middle portion of the long unique region of VZV genome was analyzed by PCR thereafter restriction enzyme digestion(PCR-RFLP). RESULTS: VZV strains isolated in Korea contained one to three copy numbers of R5 TDR. Of 61 isolates, 43(70%) comtained 2 copies of R5 TDR, while 11(18%) isolates contained only one copy and 7(12%) isolat s contained 3 copies. About 16% of the strains examined did not have a PstI cleavage site, although the majority of strains retained this site. VZV strains could be classified into 6 strains on the basis of the copy number of R5 TDR and PstI cleavage site, in which the strain with 2 copies of R5 TDR and PstI cleavage site positive was the most frequent type (36 out of 61 isolates) in Korea. Four batches of live attenuated vaccine(Biken) that is now used in Korea showed 2 copy numbers of R5 TDR and PstI site negative. CONCLUSION: The copy number of R5 TDR and the presence of PstI cleavage site seems to be a reliable marker for dicrimination of VZV strains in Korea. This discrimination can be used to study the molecular epiclemiology of VZV and as a criterion for identification of vaccine-related isolates.

Atresia of larynx is a rare fatal anomaly that should bring an immediate medical attention for proper managenent. We reported a case who died in neonatal period because of respiratory difficulty. His first problem was difficulty of inserting tracheal tube through the larynx. It was of interest in this case that he was presented with generalized edema and also massive lung edema. The lung was characterized by total absence of squamous and amniotic debris in the alveolar spaces and massive inflation of the alveoli by clear fluid that was thought to be amniotic fouid produced by the lung per se. Because there was no connection between oral cavity and the lungs, there would be no way the amniotic fluid outside the fetus. The laryngeal atresia was of infraglottic type and was complete with dispalced cricoid cartilage. Associated anomalies were left persistent supperior vena cava, perimembranous ventricular septal defect, spina bifida and focal cerebellar heterotopia.

OBJECTIVE: The patients of endometriosis may complain of dysmenorrhea, pelvic pain, and dyspareunia, but may be asymptomatic. We studied on the correlation between the pain and the psychologic stress, Also, we studied on the correlation between serum CA-l25 levels and the psychologic stress. METHODS: The data was obtained from il7 endometriosis patients. Psychological stress was studied with STAI(Stait-Trait Anxiety Inventory) and BDI(Beck Depression Inventory). We compared the degree of anxiety and depression according to existence of pain and the duration of pain. Also we examed the scores of STAI and BDI according to the level of serum CA-125. RESULTS: The pain group had more depression and anxiety, in comparison to the pain-free group. And the depression and anxiety significantly increased in long-term pain group. There was no correlation between the level of serum CA-125 and the depression,or axiety. CONCLUSION: The pain of endometriosis may play a role of pychological stress to the patients, so it seems to increase depression and anxiety.

Measurement of bone mineral density(BMD) of the spine may be affected by the presence of various factors such as osteophytes, osteosclerosis and spinal deformity, particularly in elderly persons. Therefore the accurate evaluation for osteoporosis is difficult in osteoarthritic spine and until now no technique can evaluate true mineral density of the osteoarthritic spine. So we performed this study to evaluate the effect of osteoarthritic changes of the spine on the BMD and various BMD values such as young-adult% and age-matched%. Additionally we evaluated the diagnostic value of the Singhs index in the advanced osteoporotic spine. We reviewed 50 patients with advanced osteoporosis of the spine retrospectively and they were divided into two groups; one consisted of 22 patients with osteoporosis alone and the other consisted of 28 patients with osteoporosis and osteoarthritic change on the spine. The measured mean BMD value in AP plane and that expressed in relation to reference data for young adults(young-adult%) of the patients with arthritic and osteoporotic spine were significantly higher than those of the patients with osteoporosis alone. On the other hand, values expressed in relation to the age and sex matched mean reference data(age-matched%) were not significantly higher in group of patients with osteoporosis and osteoarthritic change, and Singh s index was not diagnostic for the osteoporosis of the spine. But young-adult% were significantly lower than agematched% even in the osteoarthritic group. We concluded that young-adult% is mare useful value for diagnosis of the advanced osteoporosis in the osteoarthritic spine.

The significance of the angle of anteversion of the femur is widely recognised, especially incongenital dislocation of the hip, cerebral palsy, Legg-Calve-Perthes' disease, and in-toeing gait, And many methods of measuring the anteversion have been described since the early work by Drehmann (1909) who determined anteversion by fluoroscopy. But there has been no reliable method of measuring the angle until recently. The authors studied the comparative accuracy and reproducibility by the use of experimental model of femur on computerized tomography, axial technique(Dunn), biplanar method (Ryder-Crane) and fluoroscopic method(Rogers) and reported the results with consideration in clinical utility. 1. The most accurate and reproducible method is computerized tomography, but it has much clinical disadvantages such as uneconomic, limited supply, more time requiring in measuring, and also limited information until the ossification of the femoral head was not occur (below the 18 months of age). 2. The next accurate and reproducible method is fluoroscopic method and it is widely useful except the case of limited motion of hip joint. 3. The Ryder-Crane's biplanar method is very difficult in clincal use because of its poor accuracy and reproducibility, difficult mtasuring technique, limited in the situation of contracture, deformity around the hip. 4. The axial technique of Dunn are also useful in any state of hip joint and simplicity in its technique. 5. The more acceptable clinical slection of measuring the femoral anteversion are the combination of the above two or three methods and comparing it with the opposite hip.
