A total of 33 patients with infective endocarditis were observed in the Guro and Hye Hwa Hospitals of Korea University Between September, 1981 and Feb, 1987. Among thses patients four patients presented with heart murmur and heart failure and had vegetation like findings observed on the two dimensional echocardiography. But these patients did not have any fever or leukocytosis in the peripheral blood and the repeated blood cultures were negative. They showed the immunologic phenomena of infective endocarditis such as microscopic hematuria in 4 patients, rheumatoid factor in 3 patients, false positive VDRL in one patient. The serum complement was decreased in 2 patients in whom it was checked. We report these 4 patients because we think these patients might be in the clinical stage in which the infecting organism is spontaneously cleared but the immunologic sequelae are remained.

Background: Hypertension results from an impaired baroreceptor reflex and enhanced sympathetic activity. The prevalence of hypertension differs among ethnicities and is more frequent in South Asians than in Caucasians, suggesting that baseline autonomic nervous system functions and their regulation may also differ among ethnic groups. In most studies, the reference values for clinical autonomic function tests are obtained from heterogeneous ethnic populations, or ethnic factors are not considered in the study design. Obtaining reference data in a homogenous ethnic group and comparing them within various ethnic groups could be helpful to detect ethnic differences in autonomic functions. The aim of this study was to identify normative reference values for standard autonomic reflex measurements in a homogeneous Korean population. Methods: A total of 181 healthy Korean volunteers (age, 20–74 years) underwent standard autonomic function tests: heart rate difference during deep breathing, Valsalva maneuver, and the quantitative sudomotor axon-reflex test. Mean and 5th and 95th percentile values were obtained for each age group. We also analyzed factors (age, sex, and body mass index) that can influence autonomic functions. Results: The heart rate difference during deep breathing and expiratory-inspiratory ratio were higher in males than in females and were inversely related to age. The Valsalva ratio was inversely related to age. Males had higher sweat volumes at all body areas evaluated than those of females, and only forearm sweat volume was significantly different between the age groups. Conclusions: Cardiovagal function was affected by age and sex in Koreans. Sudomotor function was affected by sex, and only forearm sweat volume was affected by age and sex. These results represent preliminary normative clinical autonomic data in a Korean population comprised of a single ethnicity

It is well known that the murine T helper cell clones are divided by their lymphokine secretory activities. One is the Th-1 cell, producing IL-2 and IFN after stimulation and the other is the Th-2 cell, producing the IL-4 and IL-5. This study was undertaken to evaluate the immunomodulatory properties of the bacterial lipopolysaccharide(LPS) on the lymphokine production in vivo and in vitro. The results were as follows: There were no effects on the lymphokine secretion by the in vitro treatment of the LPS. The in vivo treatment of the LPS decreases the capability of the production of IL-2 and IFN , whereas it increases the capability of IL-4 production. The altered capacity of the lymphokine production was recovered about 2 weeks after the treatment of the LPS. There were no differences on the lymphokine production between E-coli LPS and salmonella LPS. The capacity of the lymphokine production was the same in the treatment of a non-heated LPS or heated-LPS. The lymphokine production of the mice which were desensitized by the long term treatment of the LPS was not different from the control mice. The in vitro treatment of RU486 can block the alterations of the lymphokine production after the treatment of the LPS. In summary, one can tell that the LPS increases the secretion of the IL-4 through the endogenous secretion of the glucocorticoids.

Congenital dislocation of the knee is very rare skeletal deformity and was firstly described by Chatelaine in 1822. Since then there have been a few number of case reports and some series discussing the etiology and treatment. The tibia is displaced anteriorly in relation to the femur. It is generally subdassified as simple hyperextention, subluxation, and dislocation depending on the degree of the joint displacement and the severity of disease. Early gentle manipulation and serial splintage or plaster cast are recommended for treatment and were successful in the majority except the case of quadriceps contrarture or late correction. The authors experienced one case of congenital dislocation of the right knee and brief review of the related literatures was made.

BACKGROUND: Moyamoya disease is a chronic cerebrovascular disorders in which stenosis of the major arteries of the circle of Willis at the base of the skull progresses to occlusion. We observed two kinds of collateral pathways from the extracranial to the intracranial arteries. Also we evaluated clinlcal and neuroimaging features of moyamoya disease to give on aid in diagnosis. METHODS: We analysed 17 patients with moyamoya disease through the medical record and neuroimaging (conventional angiography and/or MR angiography) review. Six out of 17 patients were children(< OR =15 years) and the other 11 patients were adults(15 years). There were 8 males and 9 females. RESULTS: In our result, moyamoya disease was more common in the adult. There was bimodal age distribution, so average age of onset in children was 8-year-old and in adult 37-year-old. Common clinical features are seizure (66%), TIA (17%), and psychotic behavior (17%) in childrens and hemorrhages (73%), infarction (18%), seizures (9%) in adults. According to angiographic staging classification of Suzuki et al. (1967), our cases showed distribution of stage I (13%), stage II (8.8%), stage III (65.3%), stage IV (4.3%), stage V (4.3%), stage VI (4.3%). In collateral vessels of moyamoya disease, there were 7 cases of ethmoidal moyamoya, 3 of vault moyamoya and 1 of mixed form. It is interesting that there were five cases of unilateral moyamoya disease and one case had pseudoaneurysm. CONCLUSION: According to our results, we may say that seizures are common in the children and hemorrhages are in the adult. Unilateral moyamoya were mainly occurred in the adult. Ethmoidal collaterals were common among collaterals and stage III had a more cases than others in our neuroimaging data. These clinical and neuroimaging data may help interpretation and diagnosis of moyamoya disease.

This is a case report of the familial olivo-ponto-cerebellar atrophy (Menzel type OPCA, OPCA III with retinal degeneration). The patient is a 37 year-old male with 5 years history of slowly progressive cerebellar ataxia, dysarthria, visual change, horizontal nystagmus and signs of pyramidal dysfunction. The CT brain scan shows significant atrophy of brain stem and cerebellum with dilatation of cisterns. His younger sister, also, has similar clinical manifestations and radiological abnormalities, but mild. By history, his mother who died at 47 years of her age looked like to have same kind of chronic disease.
