A case of neonatal diabetes mellitus is described. The child presented with low birth weight but was normal in appearance. She was acidotic and ketonuria was observed. The HLA typing was DR1 and 3, and insulin autoantibodies were negative. Genetic analysis with polymorphic DNA markers for chromosome 6 indicated biparental inheritance. She required insulin therapy for the control of hyperglycemia, and insulin dependence continues after 8 months of age.

Objective: Vasospasm remains the leading cause of cerebral damage after aneurysmal subarachnoid hemorrhage. Although magnesium regulates the calcium influx in vascular smooth muscle and endothelial cells, it has not been reported whether L-type calcium channels are involved in magnesiuminduced vascular relaxation in rat basilar artery. So, the effect of magnesium sulfate on L-type calcium currents in freshly isolated smooth muscle cells from rat basilar artery was investigated. Methods: The smooth muscle cells were isolated from rabbit basilar artery by enzyme treatment. L-type Ca2+ currents were identified using cesium chloride, a potassium channel blocker and Bay K8644, an activator of L-type Ca2+ channel. Currents were recorded under step pulse whole cell patch clamp technique. Results: In the presence of cesium chloride (in pipette solution), inward currents were observed by depolarizing step pulses. The inward currents were significantly reduced by nimodipine (n=4, p<0.05), an L-type Ca2+ channel blocker and increased by Bay K8644 (n=5, p<0.05), an L-type Ca2+ channel activator. The L-type calcium currents (156±17.0 pA, n=12) were significantly reduced by the application of 5 mM magnesium sulfate (53.8±7.0 pA, n=12, p<0.01). Conclusion: These results suggest that magnesium may relax cerebral vessel of rat basilar artery through decreasing intracellular Ca2+ ion by inhibition of L-type Ca2+ channels.

This study was performed to characterize the humoral immune responses with isotype profiles in Mycobacterium tuberculosis infection. PPD-Specific IgG and IgG subclasses were measured using ELISA in 212 patients with pulmonary tuberculosis. The values of PPD-specific IgG were significantly higher in pulmonary tuberculosis patients than those in the control group, and were correlated to the severity of illness (P < 0.01). The specificity and sensitivity of ELISA for IgG antibodies were 1.0 and 0.81, respectively as determined in 212 sera from tuberculosis patients and 44 from healthy controls. The positive predictive value was 1.0 (171/171), while negative predictive value was 0.52 (44/85). The values of PPD-specific IgG were significantly decreased after 2-4 months of treatment. Among the moderately and far advanced pulmonary tuberculosis patients, the values of PPD-specific IgG were significantly decreased in responders after 6 months of treatment. However, PPD-specific IgG in nonresponders was increased (P < 0.01). PPD-specific IgG subclass responses were evident to all four IgG subclasses. No changes of isotype response according to the severity of the disease were observed.

This study was performed to evaluate the changes of serum IgG4 level in children with allergic diseases. Serum Ige, IgG and IgG4 level were measured using enyzme immunoassay (IgE) and radial immunodiffusion method (IgG and IgG4) in 21 children with bronchial asthma, allergic rhinitis or urticaria Eosinophil counts in peripheral blood and the values of serum IgE were significantly increased in allergic patients. The values of IgG4 in allergic patients were also increased compare to those in controls (24.23mg/dl versus 20.33mg/dl). But the values of IgG4 were not significantly correlated to either IgG or IgE levels. Further studies will be needed for measuring allergen specifie IgE and IgG4 levels considering the onset of diseases, methods and duration of treatment.

Individual tumors, even those of the same histologic type, show varying sensitivity to specific cytotoxic agent. Therefore, sensitivity testing assume an increasingly important as an orientational aid in planning chemotherapy. In the past decade there have been many attempts to develop a chemosensitivity test that would predict the clinical effectiveness of various chemostherapeutic agents against human neoplasms. In the United States National Institue's anticancer drug screening program, a colorimetric assey based on the ability of live cells to reduce a tetrazolium-base compound(MTT) to a blue formazan product was used. There has been an increase in reports of a chemosensitivity assay that use tetrazolium dyes and current the assay is in use in our country. The efficacy of several anticancer drug (vincristine sulfate, Etoposide, doxorubicin CDDP) were evaluated using the in vitro chemosensitivity of MTT assay with two cancer cell lines (MOLT-4, KHOS/NP). The follows obtained. 1) CI50 on MOLT-4 are 0.55ng/ml and 0.81ng/ml for vincristine and oncovin, 142.30ng/ml and 78.75ng/ml for lastet and vepesid, and 19.75ng/ml, 20.43ng/ml and 8.66ng/ml for ADR, ADM and adriblastin, respectively. 2) CI50 on KHOS/NP are 691.35ng/ml, 873.73ng/ml, 1,205.22ng/ml, 768.81ng/ml and 672.19ng/ml for cisplan, cisplatin, cispatin, platinol and cisplatin G, and 9.22ng/ml, 11.46ng/ml and 4.28ng/ml for ADR, ADM and adriblastin, respectively. In conclusion the MTT dye reduction assay to anticancer drug sensitivity using short-term microplate culture might serve as a reliable tool for the selection of effective chemotherapeutic agents in patients with cancers.
