1.Radiographic Appearance of the Symphysis Pubis: Criteria of Diastasis of Symphysis Pubis after Normal Delivery.
The Journal of the Korean Orthopaedic Association 1999;34(5):969-972
PURPOSE: This study was performed to evaluate the width of symphysis pubis and its radiographic appearance in different age and sex, and it was aimed to establish a radiographic diagnosis criteria for diastasis of the joint. MATERIALS AND METHODS: The width and the appearance of symphysis pubis were observed by pelvic X-ray in 92 males and 169 females who had no history of any joint disease. The mean width of symphysis pubis was calculated and data were analyzed by age, sex and parity using student t-test. RESULTS: The mean width of symphysis pubis was 2.88+/-0.71 mm in male group and was 3.24+/-0.68 mm in female group. It was 3.34+/-0.84 mm in parturient and 2.82+/-0.55 mm in nullipara and the difference between these two groups was significant (P<0.05). Osteoarthritic changes were noted in most cases over 60 irrespective of sex. CONCLUSIONS: Based on the results from this study and reported value of physiological relaxation of symphysis pubis through pregnancy and labor, a separation over 6 mm and/or a vertical migration over 3mm can be diagnosed as diastasis of symphysis pubis. This criteria would facilitate the earlier diagnosis of relaxation and separation of this joint by labor or trauma.

BACKGROUND: The proliferation of vascular smooth muscle cell(VSMC) is a part of the major pathogenic mechanism for atheroscle- rosis. It has been reported that L-type calcium channel plays a role in the VSMC proliferation in diabetic rats. But there is a little study results about the association between L-type calcium channel and VSMC proliferation by glucose concentrations in culture media. So we examined the association between voltage-dependent L-type calcium channel of VSMCs and the proliferative activity of vascular smooth muscle cells. METHODS: Rat aortic VSMCs were isolated from the aorta of OLETF rat by enzyme method. VSMCs were cultured in various concentrations of glucose(5.5, 25 mM). The VSMCs(1x104 cells in 24-well plates) were incubated in the presence of Bay K 8644 (10-6M) with/without verapamil(10-6M) for 48 hours. Then the proliferation was assessed by MTT(methylthiazole tetrazolium) assay and expression of L-type calcium channel mRNA was measured by RT-PCR. RESULTS: The proliferative ability and the expression of L-type calcium channel of cultured VSMCs were increased dose-dependently by the glucose concentrations(p<0.05). Bay K 8644 enhanced the proliferation of VSMC and verapamil blocked the incremental effects induced by Bay K 8644. CONCLUSION: These results suggest that L-type calcium channel may play a role in VSMC proliferation of OLETF rat.

14-3-3 proteins are cytoplasmic proteins of about 29 kDa and have a minimum of seven isoforms. This protein is important in signal transduction with the ability of binding with phosphoserine of many signalling proteins. We expressed 14-3-3 protein tagged with 6 histidine residues in E. coli and purified the protein by nickel affinity chromatography. Using this purified protein as an antigen, we made rabbit antisera and mouse monoclonal antibodies to 14-3-3 zeta isoform. We subcloned cDNA of 14-3-3 zeta isoform derived from HeLa cell lamda gt 11 library into an E. coli expression vector which is designed to express heterologous protein with N- terminal 6 hidtidine tag. BALB/c mice were immunized with purified 14-3-3 protein and the hybridoma clones which produce monoclonal antibodies angainst 14-3-3 protein were selected. These monoclonal antibodies reacted with the recombinant protein expressed in E. coli as well as the 29-kDa native protein in various cell lines. However, they did not immunoprecipitate 14-3-3 protein. The monoclonal antibodies produced in this study can be valuable tools for the identification of the 14-3-3 in signal transduction study.

Solid pseudopapillary tumor of the pancreas is a rare tumor that affects young females with low malignant potential and good prognosis with more than 90% survival at 5 years. Metastasis is very rare. We report the case of a 74-year-old female who had pancreatic solid-pseudopapillary tumor and synchronous hepatic metastasis.

It has been postulated that programmed cell death via apoptosis may be critical for remodelling of glomeruli after inflammatory injury. To understand the regulatory mechanism of apoptosis in experimental crescentic glomerulonephritis (CGN), we examined the MIB-1 score (proliferation index, PI) and apoptotic index during the progression of experimental CGN to end-stage renal failure. CGN was induced in New Zealand White rabbits by administration of guinea pig anti-GBM IgG after sensitization with guinea pig IgG and their kidneys were analyzed for the development of crescents through sequential renal biopsies. Serum creatinine levels progressively increased in a time course until day 45. The PI in glomeruli, tubular epithelial cells, and interstitium progressively increased during the progression of experimental CGN. The mean numbers of MIB-1 positive intraglomerular nuclei (PI) were significantly correlated with degrees of crescent formation and the numbers of apoptotic cells in the glomeruli, tubules, and interstitium. Significant apoptosis was present from day 1 (15.8 10.16 cells/glomerular cross section) and increased in number with the proliferative lesions as glomerular inflammation continued. Moreover, apoptosis increased during the resolution of the glomerular inflammation, and many apoptotic cells were present in the sclerotic lesions in day 17 (18.6 12.99 cells/glomerular cross section). As glomerular inflammation subsided, cellular crescents progressed to fibrous crescents with a reduction of cellularity by day 45. On day 45, the glomerular PI and the numbers of apoptotic cells were markedly decreased. The correlations found in CGN between the creatinine level and the percentage of crescents, between the percentage of crescent and PI, and between the PI and number of apoptotic cells support the hypothesis that there is a change in the glomerular and tubulo-interstitial apoptosis under pathologic conditions. These findings indicate that apoptosis plays an essential role in the resolution of intra- and extraglomerular inflammation and in the elimination of glomerular cells within the sclerotic regions for progressive CGN. The regulation of the apoptotic phenomenon and increased PI during CGN may be important in the progression of glomerular inflammation and the development of pathologic glomerular sclerosis.

Authors experienced a 13-day-old boy who had suffered from walnut sized hard erythematous nodules on left axilla, anterior and posterior aspect of the neck which began to develop 9 days after birth. Histopathologic findings revealed subcutaneous fat necrosis and needle-shaped cleft in several fat cells. The skin lesions spontaneously resolved at 2 months of age. The clinical pattern, the skin manifestations, and the histologic appearance of the lesions were diagnostic of subcutaneous fat necrosis of newborn.

9.Epidural Narcotics and Multiple Fractured Ribs.
Korean Journal of Anesthesiology 1988;21(6):1030-1032
Pain relief becomes a major concern when treating patients with rib fractures so adequate ventilation must be maintained. Many techniques have been described for the management of frectured ribs, including systemic analgesics, intercostal nerve blockade, intrathecal morphine, epidural bupivacaine and epidural morphine. This case report illustrates the successful use of epidural narcotics in a patient with multiple fractured ribs.

10.Malignant Hyperthermia Syndrome - A case report.
Korean Journal of Anesthesiology 1988;21(6):1007-1010
The popular term malignant hyperthermia syndrome (MHS) refers to a clinical syndrome classically observed during general anesthesia. It is characterized by a rapidly increasing .temperature and a high mortality rate. A case of MHS was experienced which developed 60 minutes after induction of general anesthesia with thiopental sodium, succinylcholine, halothane, N2O and 02. High fever, muscle rigidity and cyanosis developed and were followed by arrythmia and unstable blood pressure. Anesthesia was terminated and vigorous emergency treatment was attempted. The patient died about 6 hours after induction of anesthesia.
