This study was conducted to examine the effect of mefenamic acid for treatment of PDA in premature newborns. Ductus arteriosus is reopened by locally produced prostaglandin E2 in a premature newborn during hypoxia. Mefenamic acid is one of non-steroidal antiinflammatory drugs acting by inhibition of cyclo-oxygenase in the prostaglandin synthesis pathway. For three premature newborns with PDA, we administered mefenamic acid and evaluated them with echocardiography to study the effect of mefenmic acid for closure of PDA. In all three babies, ductus arteriosus was closed successfully. We feel that mefenamic acid is safe and effective medication for treatment of PDA in premature newborns, but further-study need to be conducted with larger numbers of cases to confirm this effect.

Congenital pseudarthrosis of the tibia is a condition most often combined with cafe-au-lait spots and neurofibromatosis. It is notoriously difficult to attain a sound bony union. Compression plating and screw fixation with massive bone graft resulted in successful union in our case.

Two hundred and eighty six cases of the fracture of the tibial shaft treated at Orthopedic Department of the Chosun University Hospital during the period from January 1974 to December, 1978. The following results were obtained. 1. Most common cases of the tibial shaft fractures were traffic accidents (66.1%). 2. The incidence of trauma was high in the young man, most frequent in the 2nd and 3rd decade (43.0%). 3. The evaluation was done according to the classification of Ellis. Among 286 cases of the fractures of tibial shaft, 139 being mild severity, 70 moderate severity and 77 major severity. 4. The group of mild severity at the fracture of upper 1/3 of tibial shaft was shown the best prognosis and the average healing period was 9.3 weeks. 5. The wound infections in the open fractures of tibial shaft were revealed 37 cases (35%) and 8 cases of chronic osteomyelitis (8%). 6. Of 54 cases, we experienced 38 cases of delayed union (13.3%), 16 cases of non-union (5.6%) and the highest rate of delayed or non-union was shown in the group of major severity at the fracture of lower 1/3 of tibiai shaft. 7. The open reduction by the compression plating reduced the time of healing period and delayed the time of healing period by the intramedullary nailing.

Meconium peritonitis is an aseptic peritonitis caused by spill of meconium in the abdominal cavity through one or several intestinal perforations which have taken place during intrauterine life or early neonatal life. We experienced three cases of meconium peritonitis with ileal perforation in two cases 1 day-old male neonate and 2 day-old male neonate, respectively, which had the chief complaint of vomiting and abdominal distension. Literatures are reviewed, briefly.

To evaluate the nephrotoxicity of cisplatin, serum levels of sodium, potassium, chloride, calcium, phosphorous, magnesium, BUN, creatinine and creatinine clearance were measured before and after administration of cisplatin in 18 cases of patients with malignant neoplasm. The results were as follows: 1) Serum calcium, magnesium, potassium and BUN levels were changed after cisplatin administration, but those changes were not statistically significant. 2) The mean value of creatinine clearance was not decreased significantly after treatment with cisplatin. 3) Acute renal failure was developed in one case, and four cases of hypocalcemia, hypomagnesemia were also detected after administration of cisplatin.

In Korea, all domestic made test systems for detecting antibodies in HIV-1 contain the antigens from human immunodeficiency type 1 (HIV-1) subtype B. However, because HIV-1 subtype O is significantly different in amino acid sequences from all other subtypes of HIV-1, there has been a need for developing a test for detecting antibodies in subtype O. For this purpose, the entire nucleotide sequence corresponding to the extracellular domain of the transmembrane glycoprotein of HIV-1 subtype O was synthesized with consideration of Escherichia coli cordon usage. Various regions of the extracellular domain were cloned into E. coli expression vectors and tested for levels of protein production. The nucleotide sequence, named ECTM, that can encode a 129 amino acid-long peptide, was found to be expressed at a high level in E. coli. The protein of approximately 17 kDa specifically reacted with sera from individuals infected with HIV-1 subtype O. The ECTM protein was purified to near homogeneity by the CM-T gel chromatography, using concentrated, denatured inclusion bodies. In Western blot analysis, the purified viral antigen reacted with sera from individuals infected with subtype O more efficiently than subtype B. The enzyme linked immunoabsorbent assay (ELISA) system was developed using the subtype O viral protein and compared with the commercially available kit lacking the antigens from subtype O. The ELISA kit containing the subtype O antigen ECTM alone efficiently reacted with sera from individuals infected with subtype O. The subtype O antigen-containing kit produced a positive absorbence even when sera were diluted 512-fold, suggesting a high sensitivity. The commercially available kit also reacted with subtype O sera, but produced a negative result at a dilution of 8-fold. Our results suggest that the currently available kit may not be able to efficiently detect subtype O sera and that the viral protein developed in this study may be added to the current system to maximize the detection of sera from individuals infected with subtype O.

p27kip1, a cyclin dependent kinase inhibitor, has been recognized as a negative regulator of cell cycle. To investigate the role of p27kip1 on progression of cancer and apoptotic pathway, we analyzed p27kip1 expression using immunohistochemical stain in 40 cases of prostatic adenocarcinoma and apoptotic index by TUNEL method in 30 cases of prostatic adenocarinoma. Both were correlated with Gleason grade and Gleason score. Loss of p27kip1 expression was more frequent in prostatic adenocarcinomas of higher score (Gleason score 7 to 10) (60.7%) than in those of lower score (Gleason score 4 to 6) (33.3%) (p<0.05). The value of mean apoptotic index of carcinoma was 1.13+/-0.26, 1.80+/-0.91, 2.06+/-0.79, and 2.12+/-0.82 in grade 2, 3, 4, and 5, respectively, and was positively correlated with grade of carcinoma (p<0.05). Mean apoptotic index of higher Gleason score (score 7 to 10; 2.05+/-0.63) was also significantly increased than in lower Gleason score (score 4 to 6; 1.34+/-0.39) (p<0.05). Mean apoptotic index in cases with and without p27kip1 expression was 1.92+/-0.86 and 1.89+/-0.81, respectively (p>0.05). These results suggest that loss of p27kip1 expression and increased apoptotic index may be the morphologic markers to predict the behavior of prostatic adenocaricnoma. The role of p27kip1 on apoptotic pathway seems to be meager in this study and needs further study.

PURPOSE: Tuberculosis is a chronic infection caused by mycobacteria species. M. tuberculosis causes disease predominantly in the lung, although every organ in the body may be involved. Retinal tuberculosis is very rare and usually unilateral. Possible hypotheses on the pathogenesis of tuberculosis-related retinal vasculitis are an infectious process and a hypersensitivity mechanism. In Korea, no case has been reported. METHOD: We experienced a case of bilateral retinal vasculitis who was suffering from tuberculous meningitis. RESULT: His vasculitis was successfully treated with anti-tuberculosis medications. We report a case of tuberculosis-related retinal vasculitis with the review of literature.
