We examined the effects of steptozotocin (STZ)-induced type 1 diabetes on cell proliferation and neuroblasts in the subgranular zone of the hippocampal dentate gyrus (SZDG) of male Wistar rats. Change in memory function was also investigated using the passive avoidance test. In the SZDG, Ki67 (a marker for cell proliferation) positive nuclei were significantly decreased at 2 and 3 weeks and slightly decreased at 4 weeks after STZ treatment. Doublecortin (DCX, a marker for neuronal differentiation)-immunoreactive (+) neuroblasts with tertiary dendrites were significantly decreased in the STZ-treated group compared to those in the vehicle-treated group. However, DCX+ neuroblasts without tertiary dendrites were abundant at 4 weeks after STZ treatment. In addition, retention latency time in STZ-treated group was similar to that of vehicle-treated group at 2 and 3 weeks after STZ treatment. However, the retention latency time was significantly decreased at 4 weeks after STZ treatment. These results suggest that STZ significantly reduced cell proliferation and neuroblasts at 2~3 weeks after STZ treatment, but not at 4 weeks after STZ treatment although memory impairment was detected at 4 weeks after STZ treatment. The gradual reduction of DCX+ neuroblasts with tertiary dendrites may be associated with the impairment of hippocampus-related memory function.

In order to understand the influence of the inducer inlet angle on cavitation and suction performance, experiments were carried out for two kinds inducer, which have the same outlet angle distribution, length and number of inducer blades. The results showed that the change of inducer inlet angles influenced not only internal flow conditions but also cavity flow and suction performance. The improvement of suction performance by using inducer were also discussed.

The epidemiology, diagnostic criteria, clinical features, symptoms and signs laboratory findings, kidney pathology, and clinicopathologic correlation of systemic lupus erythematosus(SLE) were analyzed. The 63 patients studied were managed at the Department of Internal medicine, CNUH, from January 1983 to December 1997. Kidney biopsy was performed in 53 patients out of 63 patients with SLE. The results were as follows: 1. The ratio of male to female was 1:26. They were 12 to 71 years old and mean age was 32.1 years old. The peak age incidence was 4th decades(30%). 2. The most frequent chief complaint on admission was generalized edema. Most patients complain two or more symptoms. 3. Immunologic and renal disorders were the most frequently observed in the ARA criteria of SLE. And the positive ANA, hematologic disorder, malar rash, and arthritis, were observed in order of frequency. 4. Among the 53 patients with renal biopsy, 30 patients revealed class Ⅳ lupus nephritis(56%), class II in 12 patients(23%), class V in 8 patients(15%) and class III in 2 patients(6%). 5. The cases of lupus nephritis represented as nephrotic syndrome were high in the class IV with 68% and class V with 86%. 6. Of 30 patients who can be followed up, 5 patients resulted in death(17 % of mortality). They "were 14 to 57 years old and mean age was 28 years old. Follow up duration were from 1 month to 6 years and 3 months, and mean duration was 1 year and 1 month, but 3 cases 7. The causes of death were as follows: Two cases were due to seizure and coma resulted from CNS involvement. One was sepsis due to miliary the & pneumonia. One was dilated cardiomyopathy and heart failure due to cardiac ac involvement. And the other one was sepsis and acute renal failure resulted from cellulitis. 8. Prednisolone was used in all patients basically, and methyl-prednisolone pulse therapy, antimalarials and alkylating agents were used in some cases. In the cases of combined therapy, the activity of SLE was well controlled.

Malignant peritoneal mesothelioma is a rare neoplasm that arises from the mesothelium of a serosal cavity and is a rapidly fatal disease with a median survival of 4 to 12 months for untreated cases. Recently, we experienced a case with malignant peritoneal mesothelioma who was suspected hepatocelluar carcioma by abdominal CT scan and was confirmed by biopsy including immunohistochemical stain(calretinin) after surgery. We performed tumor excisions and wedge resection of the liver(segment Ⅷ)and inserted Tencoff catheter in abdominal cavity at 25th day of post-operation. We treated with intraperitoneal paclitaxel(25mg/m^(2)/day for 5 days) six courses monthly. She was well tolerable and is still living without any evidence of recurrence for 14th month of post-operation.

저자들은 Carbamazepine을 임상에서 사용하면서 가장 심각하게 문제가 되는 독성 표피 괴사융해증 1례를 경험하였기에 문헌 고찰과 함께 보고 하였다. 정신과 영역에서 Carbamazepine의 사용이 증대함에 따라 많은 부작용이 보고 될 것이다. Carbamazepine 치료 중에 기본적인 혈액 검사, 전해질 검사, 간 기능 검사, 심전도, 뇌파 검사, 적절한 혈증 농도 검사와 세심한 임상적 주의가 부작용을 최소화하고 치료 효과를 크게 할 것이고 독성 표피 괴사융해증이 의심될 경우에는 혈액 전문의와 전문의에게 자문 의뢰하는 것이 필요할 것이다. The authors reported one case of toxic epidermal necrolysis that occurred in the carbamazepine treatment in a 47-year old male patient with aggressive organic mental disorder. This case developed toxic epidermal necrolysis while taking carbamazepine with a dose of 600mg/day. Toxic epidermal necrolysis did not improve after discontiuation of carbamazepine. We reviewed incidence and the natural history of toxic epidermal necrolysis.

Acute renal failure is a frequent complication in hospitalized patients and is strongly related to the mortality. The Clinical outcome and prognostic factors of acute renal failure(ARF) have been analyzed by many authors. The present study describes the etiologic and clinical aspects, as well as other factors related to mortality. All the patients suffering from acute renal failure admitted during the period of January 1993 - August 1998 were included in the study. The average age of the patients was 52±17 years and mortality rate was 24%. The causes of acute renal failure were hemorrhagic fever with renal syndrome(HFRS), sepsis, renal hypoperfusion, urinary tract obstruction, acute tubular necrosis, etc. The etiology of ARF was a significant prognostic factor on mortality in ARF. Other significant prognostic factors were oliguria, organ failure, use of vasoconstrictors, hypotension, serum bicarbonate, premorbid conditions, sepsis, neurologic complications, gastrointestinal bleeding. On the other hands, operation, sex, anemia, thrombocytopenia, hypoalbuminemia, BUN, serum creatinine, and hyperkalemia were not significant factors for the mortality. We conclude that major prognostic factors of acute renal failure arc premorbid conditions, sepsis and multiorgan failure, and they are responsible for persistent high mortality of acute renal failure despite of advances of medical care.

Objectives : We aimed to identily the degree of perceived need and use of child mental health services, and to examine the factors associated with the perceived need and use of the child mental health services. Methods : The sample consisted of 3,477 children aged 8 to 13 years. The parents completed the sociodemographic data, the Korean version of the Child Behavior Checklist (K-CBCL), and the Korean version of DuPaul's Attention Deficit Hyperacti-vity Disorder Rating Scale (K-ARS). Results : Overall, 10% of children demonstrated the need for mental health services, and 2.36% utilized the child mental health services. All subcategoiy scores of K-CBCL and K-ARS were significantly low in the no help needed group. Factor sassociated with the actual use ofchild mental health services included social problems and thought problems. Conclusion : The demand for child mental health services is high, but only a small number of children are using mental health services. To increase actual use, it is necessary to educate and campaign for various child mental health.
