The polyglandular autoimmune(PGA) syndrome designate as the dysfimction of endocrine and nonendocrine systems involving two or more organs on the basis of an autoimmune mechanism. There are 3 types of PGA syndrome and their etiology or pathogenesis is still not complete by understood. Type I PGA is present in the patients who have at least two of the triad of Addison's disease, hypopacathyroidism, and chronic mucocutaneous candidiasis. Type II PGA is present in the those who have Addisons disease with autoimmune thyroid disease and/or insulin dependent diabetes mellitus, but who do not have hypoparathyroidism or candidiasis. Type III PGA is present in the one who have autoimmune thyroid disease, without Addisons disease, but with another autoimmune disease report a case of autoimmune polyglandular syndrome type II in a seventy-three years old female patient who had primary adrenal insufficiency, primary hypothyroidism, and empty sella, pulmonary tuberculosis.

PURPOSE: In this study, we compared the quantitative characteristics of dynamic salivary gland scintigraphy with static scintigraphy in patients with clinical sicca syndrome using Tc-99m pertechnetate. MATERIALS AND METHODS: Fifty-two parotid glands and 52 submandibular glands out of 26 patients with clinical sicca syndrome were studied by dynamic and static salivary gland scintigraphy. Ten normal volunteers were also studied as a control group for comparison of scintigraphic parameters. Ten minutes after injection of 370 MBq Tc-99m pertechnetate, we obtained pre-stimulus static images for a few minutes. Then dynamic salivary gland scintigraphy with lemon juice stimulation was performed for 20 minutes. Finally we obtained post-stimulus static images after dynamic images. On dynamic study, functional parameters such as uptake rate, secretion rate and re-uptake rate were calculated. The results of dynamic study and static images were compared. RESULTS: On dynamic study, we could obtain functional parameters of salivary glands successfully. On dynamic study, 22 parotid glands and 22 submandibular glands out of each of 52 glands are abnormal. The static images demonstrated somewhat different results, of which reasons we could assume via dynamic study. CONCLUSION: Dynamic salivary gland scintigraphy using Tc-99m perechnetate were more functional than static images and might be useful in the assessment of the functional change of the salivary gland in patients with clinical sicca syndrome.

Primary hypothyroidism can result in reactive enlargement of the pituitary gland which is indistinguishable from primary pituitary lesions in clinical presentation and on magnetic resonance imaging. A 17-year-old girl came to the hospital due to short stature, general weakness and galac-torrhea. The magnetic resonance imaging (MRI) study showed pitutary enlargement. The hormone study showed hyperprolactinemia, decreased basal growth hormone level and primary hypothyroi-dism. By thyroid replacement therapy only, mass was successfully regressed on follow up MRI after 4 months, and growth acceleration could be achieved.

BACKGROUND: Insulin resistance syndrome shows extreme insulin resistance and is associated with acanthosis nigricans. We can differentiate it into type A insulin resistance that has insulin receptor defect, and type B insulin resistance due to insulin receptor autoantibody. Type B insulin resistance was firstly described by Kahn in 1976. It was often found in adult female and showed autoimmune characteristics. As clinical characteristics, there are hyperglycemia, hypoglycemia, hyperinsulinemia, extreme insulin resistance and acanthosis nigricans. METHODS: We investigated 17 insulin receptor autoantibody positive cases and 8 cases of normal control who had visited Wonju Christian Hospital from October 1994 to December 1995. Among insulin receptor autoantibody positive subject, male was 4 cases and female 13 cases. Their mean age was 42.2. We compared patients who had insulin receptor antibody positive acanthosis nigricans(IRA) with normal controls. IRA patients were 6 cases(35.3%) of nomal glucose tolerance, 11 cases(64.7%) of abnormal glucose tolerance including overt diabetes mellitus. RESULTS: The 11 cases(64.7%) among IRA patrents were obese and 13 cases(76.5%) had hyperininsulinemia. In IRA patients, mean serum insulin concentration during oral glucose tolerance test was 202.1mU/mL and it was greater than 46.3 of normal controls. Insulin sensitivity in 1.79mg/L * mM * xmU * min normal controls was higher than 0.74mg/L * mM * min of IRA patients. CONCLUSION: IRA patients showed abnormal glucose tolerance including overt diabetes millitus, severe insulin resistance, hyperinsulinemia and obesity.

PURPOSE: The replacement of functional genes into cells that lack genes or mutant genes is the basis of gene therapy. In cancer, where cells often have multiple genetic defects, the replacement of critical genes may suffice to suppress cell growth or induce cell death. In malignant brain tumors, p53 mutation are among the most frequently observed genetic findings and inactivation p53 suggests that p53 plays a critical role in carcinogenesis and tumor progression. Therefore, we study the successful transfer of the wild-type p53 gene using a replicative deficient adenovirus vector into human glioma and medulloblastoma c~ell lines. Meterials and Methods: The human glioma cell line T-98G, U-87MG, U-373MG were used. To determine the efficiency of the adenovirus vector, cell lines were transfected with the Ad-p gal and analysed with X-Gal staining. Cell viability was determined by trypan blue exclusion every day after infection and Westem blot analysis was used to conform the expression of the exogenous p53 protein. RESULTS: Cell growth of the Ad-CMV-p53 infected U-373MG, and U-87MG was significantly suppressed. It appeared that exogenous p53 protein expression had an earlier ad more profound suppressive effect on U-373MG having a mutated p53 gene than on U-87MG having a wild-type p53. The expression of the exogenous p53 was more than 10 times higher than the expression of the endogenous p53. To examine the decreased viability, U-373MG was stained with Hochest 33258 and detected nuclear condensation and apoptic body. Staining results suggest that cells undergo apoptosis. CONCLUSION: The replicative deficient adenoviral vector can transfer and express p53 in human glioma cell lines in vitro, restoring wild-type p53 tumor suppressor functions. The restoration of normal p53-encoded protein in the mutant ceil lines induced cell death. The high expression of the newly transduced protein had different effects on the growth rate of the infected cell lines depending on the p53 status of the cells.
