Immune complex deposits have been found in the choroid plexus in patients with systemic lupus erythematosus, and it can be assumed that an immune complex injury to the choroid plexus might be related to the neuropsychiatric disorder seen in patients with SLE. Acute serum sickness was experimentally induced in rabbits by intravenous injection of crystalized BSA. Prednisolone in conventionl dosage was administered to study the immunologic injury of the choroid plexus as well as the mechanisms involved in the prednisolone effect. Light, electron microscopic and immunofluorescent studies were made. The host immunoglobulins(IgG, IgA, IgM) and beta 1 C globulin were demonstrated in the choroid plexus. Histopathological findings included mild to moderate interstitial and perivascular lymphocyte and plasma cell infiltrations and edema. Control animals showed no immune deposits and no histopathologic changes. Electron microscopic findings comparing the immunofluorescent and histopathologic changes were minimal, and showed sparse, vague electron dense deposits particularly in the interstitial spaces, knob-like focal thickening of vascular basement membrane, swelling of endothelial cells, and some accentuation of interstitial cells. The morphologic and functional similarities of the choroid plexus and glomerular basement membrane, the findings in morphologic, electron microscopic and immunofluorescent examinations of the experimental rabbits, along with the observed effects of prednisolone, together with similar reports in the recent literature suggest that immunologic injury of the choroid plexus could be considered as a new disease entity. This immunologic injury might play a significant role in neuropsychiatric disorders in the long standing immune complex deposit diseases. The very interesting finding is the nature and function of the interstitial cell between the endothelial (vascular) and epithelial side basement membranes, and speculation as to whether or not the role of this interstitial cell in choroid plexus injury may be in its possible analogy with glomerular mesangial cells.

T cell activation is a critical event for initiation and regulation of immune responses and inhibitors of such signaling pathways are clinically useful for the treatment of patients received allogratt and autoimmune disease. In the course of screening soil microorganisms from the forest of Cheju island in Korea for new immunosuppressive agent, one of Streptomyces species (CK-95441) was found to produce a new immunosuppressant, tautomycetin which also had antifungal activity. Tautomycetin showed the inhibition of T cell proliferation in murine mixed lymphocyte reaction (MLR) and T cell activation induced by concanavalin A. Tautomycetin also blocked the induction of IL-2 gene expression which was examined in Jurkat TAg cell line in which multiple NFAT-binding sites and minimal IL-2 promoter drive the production of B-galactosidase. Also, the level of inhibition in activation-induced IL-2 receptor expression by tautomycetin was greater than those by cyclosporin A measured by flow cytometry. But, Fas ligand-induced apoptosis in Jurkat cells was unaffected by tautomycetin which was measured by DNA fragmentation assay. These results suggested that tautomycetin will be able to be used as a potent immunosuppressive drug following organ transplantation.

Borderline malignant ovarian tumor are characterized as neoplasrns exhibiting cellular priliferative changes greater than those seen in the benign form, but not showing destnictive invasion of the ovarian strama. We reviewed 14 cases of borderline ovarian tumor who had been diagnosed and treated at Kyung Pook university hospital from 1987 to 1992. We nnalysed the clinical features, treatment and prognosis which were compared to 24 cases of the epithelial ovarian cancer at the same period The most common histological thpe of boderline tumnr was mucinous type (1 l cases, 79%), the next one was serous type (3 cases, 21%). In FIGO stage of Borderline tumor, 11 caseS weve stage I a, 1 with stage II c, 1 with stage gb and 1 with stage lV, and the FIGO stage of 24 cases of ovarian cancer was 8 cases with stage I a, 1 with stage I b, 2 with stage I c, 1 with II c, 2 with stage III a, 1 with stage III b, 7 with stage III c and 2 with stage 1V. The mean age of borderline and malignant tumor was 37.1 and 47.6 years.. 3 cases were being pregnant on the operatian. In the 14 cases of borderline turnor, 7 cases were managed by conservative operation, but 1 case recurred 4 years later so extirpative operation and pastoperative chemotherapy were given. The other 4 cases were managed by extirpative operation but postoperative chemotherapy was given in only 1 patient. Follow up ranged from 7 to 72 months. 12 cases were alive. 2 cases died, one was stage III b, the other was atage IV. This atudy suggeat, that it is neceasary to follow up carefully even the early stage of botderline tumor and manage as oyarian carcinama in the advanced stage.

A patient had total occlusion of the left main coronary artery that was proved by coronary arteriography. Patients with total occlusion of the left main coronary artery have a varying clinical presentation and may have prolonged survival. In patients with good collaterals, left ventricular function may be preserved. This report reveiws the clinical and angiographic findings of a patient with occlusion of the left main coronary artery with symptoms of unstable angina pectoris but without congestive heart failure or EKG evidence of myocardial infarction.

Acute suppurative cholangitis is a severe inflammatory process of the bile duct occurred as a result of partial or complete obstruction of the bile duct, and may manifest clinically severe from of disease, rapidly deterioration to life-threatening condition. We analyzed emergency percutaneous transhepatic biliary drainage in 20 patients of acute suppurative cholangitis with biliary sepsis to evaluate the therapeutic effect and complication of the procedure. The underlying causes were 12 benign diseases(stones) and eight malignant tumors and among eight malignant tumors, bile duct stones(n=4) and clonorchiasis (n=1) were combined. Percutaneous transhepatic biliary drainage was performed successfully in 17 of 20 patients improvement of general condition and failed in three patients. The procedures were preterminated due to the patient's condition in two and biliary-porto fistula was developed in one. After biliary decompression by percutaneous transhepatic biliary drainage, effective and successful elective surgery was performed in nine cases, which were seven biliary stones and two biliary cancer with stones. Our experience suggests that emergency percutaneous transhepatic biliary drainage is an initial and effective treatment of choice for acute suppurative cholangitis with sepsis and a safe alternative for nonsurgical treatment.
