The bipolar hemiarthroplasty is one of the treatment methods of the avascular necrosis of the femoral head and the fracture of the femur neck. The mechanism of bipolar hemiarthroplasty is intended to distribute the forces at the site of the inner and outer articulation, and theoritically diminish acetabular wear and produce a painless arthroplasty. The authors analyzed motion of two components in 23 cases of the bipolar hemiarthroplasty, performed at the Department of Orthopaedic Surgery, Korea University Hospital, between January, 1985 and January, 1993 with average 47 months follow up(range 24 to 84 months). The results obtained were as follows: 1. In the motion of the two components, inner bearing motion was average 11.5 degrees(from 1 to 29 degrees) and outer bearing motion was average 21.4 degrees(from 3 to 45 degrees). 2. The inner bearing motion was highest at 12 months with average 16 degrees and outer bearing motion was lowest during the same period with average 15 degrees. During the follow up the inner bearing motion was decreased whereas outer bearing motion was increased. 3. The inner or outer bearing motion of bipolar component was no correlation with age, sex and clinical result.

This study was undertaken at the department of Obstetrics and Gynecology, Chonnam University Medical School, to investigate the association between some of the risk factor and the incidence of intrauterine fetal growth restriction(IUGR). The studied population was selected from patients who admitted at Chonnam University Hospital during January, 1992 through May, 1997, with following criteria, Korean, singletone pregnancy with live birth and known gestational weeks with 28 or more. And then, the risk factors were analyzed in terms of maternal factor, placental factor, and fetal factor. The following results were obtained. 1) The incidence of IUGR was 6.1%. 2) The incidence of IUGR was higher at young aged mother and nullipara. 3) Only 39.1% of etiologic factors for IUGR was found to have known causes. According to the risk factors for IUGR, hypertensive disorder during pregnancy, anemia, cardiac disease, leukemia, and pulmonary tuberculosis were associated with increased incidence of IUGR. 4) The relative risk of IUGR was much higher in neonates born with congenital anomalies. 5) According to the placental causes of IUGR, placenta previa and placenta abruption showed some association with IUGR.

In order to evaluate the effect of fluconazole on Candida albicans induced keratitis, an experimental study was conducted on 30 rabbits. After 4 days of inoculation with Candida albicans on rabbit cornea, animals were divided into three treatment groups: daily treatment with a single oral dose of 50mg fluconazole(group 1); topical therapy with 0.3% fluconazole solution 6 times a day(group 2); control animals without any medical treatment(group 3). The rabbits were treated for 28 days following completion of Candida albicans inoculation, and the severity of keratitis was examined with a slit lamp biomicroscope every two days throughout the treatment period. After the treatment, animals were sacrified and histopathological study of the corneas were per formed. Animals in group 1 and 2 showed significant improvements in keratitis compared to that of control animals beginning 10 days of treatment(p<0.05). No statistically significant difference between the group 1 and group 2 were noted in response to treatment(p>0.05). Thus, we suggest that fluconazole is effective in treatment of keratitis induced by Candida albicans.

Although the incidence of the Penicillium keratitis increases, there is no available reports from the literature. Dense, gray-whitish infiltration combined with ulceration was observed at the central cornea of 62-y-o-man. Hypopyon was observed also. Colonies on Sabouraud's agar showed light violet pigmentation. On the light microscopic examination of the recipicent cornea after penetrating keratoplasty, proliferation of the fungal hyphae in the deep corneal stroma was observed, but collagen fibers of the superficial stroma were re-formed over the necrotic stromal tissue. Electron microscopy showed a hiypha with triple cell wall.

The current paper reports on a case of subdural empyema secondary to frontal sinusitis in an otherwise healthy child. Sinusitis is a common and benign condition in most pediatric cases. Because of the widespread use of antibiotics, intracranial extension of pediatric sinusitis is rarely seen today; however, complications (e.g., cavernous sinus thrombosis, orbital infection, meningitis, and subdural empyema) are potentially life threatening. A 15-year-old right-handed male presented with a 3-day history of fever, headache, and left-sided palsy. Computed tomography revealed right-sided subdural empyema with right frontal sinusitis and maxillary sinusitis. A postoperative inpatient neurological consultation was requested 2 months post-surgery due to motor function deficits. The results suggested that early and accurate diagnosis of subdural empyema leads to prompt treatment and a favorable outcome for the patient.

OBJECTIVE: The purpose of this study was to evaluate the efficacy and effect of various cryopreservation method on the survival and the cytoskeletal stability of metaphase II mouse oocyte. METHODS: Mouse ovulated oocytes were collected and cryopreserved by a modified slow-freezing method with 1.5 M 1,2-propanediol (PrOH)+0.1 M sucrose or by vitrification using cryo loop and EM grid with 40% ethylene glycol+0.6 M sucrose. Four hours after thawing, intact oocytes were fixed and stained with fluorescein isothiocyanate (FITC)-conjugated monoclonal anti-beta-tubulin antibody to visualize spindle and propidium iodide (PI) to visualize chromosome. Spindle morphology was classified as follows: normal (barrel-shaped), slightly and absolute abnormal (multipolar or absent). RESULTS: Survival rate of the frozen-thawed oocytes in vitrification group was significantly higher than that of slow-freezing group (62.7% vs. 24.4%, p<0.01). Vitrification with cryo loop showed significantly higher survival rate than that with EM grid (67.7% vs. 53.5%, p<0.05). On the other hand, proportion of normal spindle and chromosome configurations of the frozen-thawed oocytes between two vitrification group was not significantly different. CONCLUSION: For mouse ovulated oocytes, vitrification with cryo loop may be a preferable procedure compared to slow-freezing method. Further study should be needed to investigate developmental competency of frozen-thawed mouse oocytes.
