To determine the effects of central nervous system (CNS) involvement in systemic Lupus erythematosus (SLE) on cerebrospinal fluid (CSF), CSF studies of 35 cases of SLE (22 cases with CNS involvement and 13 cases without CNS involvement) were analyzed and compared with 20 normal CSF studies. The mean values of several CSF parameters were significantly changed in the group of SLE with CNS involvement (increased protein, white blood cell (WBC) counts and pressure, and decreased glucose contents), but not in the group of SLE without CNS involvement. In 22 case of SLE with CNS involvement, 10 cases (45.5%) were more than 4 WBC's in CSF, 12 cases (54.6%) more than 40 mg/dl of CSF protein and 8 cases (36.4%) less than 40 mg/dl of CSF glucose. CSF pressure was increased more than 200 mm CSF in 41.2%. On the other hand, in 13 cases of SLE without CNS involvement, the CSF studies were almost normal except 4 cases (30.8%) of more than 40 mg/dl in CSF protein.

In order to investigate the risk factors of ischemic brain stroke (IBS) in diabetic patients, we analyzed 416 cases selected from 6239 diabetic patients admitted to Severance Hospital from Jan. 1983 to Dec 1987. Two hundred and eight cases had IBS. The other 208 cases without IBS were selected as a control group by a stratified random sampling method. The two groups were compared using various clinical characteristics of diabetes mellitus (DM) and known risk factors of IBS. In diabetics with IBS, the duration of DM was longer (9.2 +/- 7.1 years), hypertension was more frequently associated (68.2%) and the serum cholesterol level was higher (213.0 +/- 55.2 mg/dl) than in diabetics without IBS (7.6 +/- 7.1 years, 32.1% and 192.1 +/- 44.8 mg/dl, respectively). By means of Stepwise Logistic Regression Analysis (SLRA), it was found that the strong risk factors were hypertension and serum cholesterol level. The serum triglyceride level, type of DM and response to diabetes treatment were also thought to be risk factors of IBS by the retrial of SLRA of residuals after exclusion of hypertension and serum cholesterol level. IBS was not significantly related to the duration of DM, fasting blood glucose level, body weight, glycosylated hemoglobin value, and serum high-density lipoprotein-cholesterol level.

The purpose of this study was to establish food ingestion factors needed to assess exposure to contaminants through food ingestion. The study reclassified the raw data of the Korean National Health and Nutrition Examination Survey in 2001 into 12 subcategories including grain products, meat products, fish and shellfish, and vegetables for international comparability of exposure evaluation. The criteria for food intake calculation were unified according to the characteristics of food groups, and recommended values for food ingestion factors were calculated through moisture correction and recategorization of cooked, processed, and mixed foods for each group. The average intake rate for grain and grain products was 6.25 g/kg-d per capita and the men's intake rate was approximately 8% higher than that of the women. The average intake rate of meat and meat products was 1.62 g/kg-d per capita and the men's intake rate was 30% higher than that of the women, on average. The average intake rate of fish and shellfish was 1.53 g/kg-d per capita, and the age groups of 1 to 2 and 3 to 6 recorded higher capita intake rates than other age groups, 2.62 g/kg-d and 2.25 g/kg-d, respectively. The average intake rate of vegetables was 6.47 g/kg-d per capita, with the age group of 1 to 2 recording the highest per capita intake rate of 9.79 g/kg-d and that of 13 to 19 recording the lowest mean. The study also offers recommended values for food ingestion factors of other food groups by gender, age, and region. The food ingestion exposure factors will need future updates in consideration of ongoing changes in food consumption behavior.

Intimal hyperplasia is considered to be a most frequent cause attributing to occlusion of a blood flow after vascular surgeries such as endarterectomy, bypass surgery and angioplasty. Clearly this response is a significant cause of morbidity in patients undergoing vascular procedures and studies to find out the strategy for avoid intimal hyperplasia are of great importance. The precise pathophysiologic pathways leading to the development of intimal hyperplasia have not been yet clear. The initial event is thought to be damage to the vascular intimal endothelium. Intimal hyperplasia is the characteristic fibromuscular cellular response on intimal injury and some author advocated the "response-to-injury" hypothesis of atherogenesis to be inducing factors of intimal hyperplasia. Endothelial cells release a number of vasoactive substances such as relaxing factor, including nitric oxide(NO). The NO has not only relaxing effect to the smooth muscle cells, but also inhibitory effect to intimal hyperplasia. In this study, we investigated on rat inhibitory effect of NO donor(SNAP, SNP) to intimal hyperplasia on endothelial denudation and reversed by coadministration of the NO synthase inhibitor, L-NAME. Balloon catheter denudation of common carotid artery was performed in 35 rats pharmacologically treated from 3 days before to 14 days after surgery(5 mg/kg/day, intraperitoneally) and divided into 5 groups: control group, without any medical treatment; SNAP group, S-Nitroso-N- acetylpenicillamine; SNP group, sodium nitroprusside; SNAP+L group, both SNAP and N(G)-Nitro-L-arginine methylester; SNP+L group, both sodium nitroprusside and N(G)-Nitro-L-arginine methylester. Animals were killed and left common carotid arteries were perfused and fixed with 10% formalin solution at 14 days after endothelial denudation. Cross sectional intima-to-media area ratios(I-M ratio, intimal area/[intimal area medial area]x100) were calculated by an image analyzer system and serum level of NO was measured directly by electrochemical methods. The results of the this experimental study were as follows: 1) Morphometric analysis of cross sections showed marked intimal thickening in the control group with an mean I-M ratio of 64.71+/-4.96%. In contrast, the I-M ratios in the SNAP group were significantly reduced by 53.14+/-7.86%(P<0.05) and in the SNP group by 43.43+/- 9.32%(P<0.05). The IM ratios of animals treated with L-NAME in group SNAP-L and group SNP-L were 68.43+/-3.91% and 67.71+/-5.50% respectively(P=NS). No significant change was noted when L-NAME was coadministered with SNAP and SNP compared to control group. 2) The serum level of NO in SNAP group(2509.7+/-354.95 nM) and SNP group(3430.4+/-236.70 nM) were significantly increased compare to control group(1339.2+/-101.04 nM)(P<0.05). Coadministration of L-NAME in group SNAP-L(1719.8+/-483.65 nM) and group SNP-L(1415.7+/-219.04 nM)were no significant changed compare to control group(1339.2+/-101.04 nM). These experiments suggest that SNAP and SNP reduced intimal hyperplasia and increased serum level of NO, reversed by coadministration of L-NAME. The relation between the intimal hyperplasia suppression and NO increase should be speculated.

The successful revascularization and reperfusion of ischemia are still associated with high systemic complication rates and severe local tissue injuries. The morality rates after revascularization have been reported to range from 10% to 20% and the amputation rates from 12% to 22%. It is well recognized that the microvasculature is highly sensitive to ischemia-reperfusion (I/R) and that the initial damage of endothelial cells contributes to I/R-induced tissue injury. In an effort to define the mechanisms responsible for reperfusion-induced vascular injury number of in vitro models have been developed to stimulate the responses of endothelial cells to I/R. Because of its simplicity, many investigators have used monolayers of cultured endothelial cells exposed to anoxia and reoxygenation as a model system to minic I/R-induced vascular changes in vivo. The endothelium serves as an important modulator of vascular homeostases by secreting various levels of both thrombotic and antithrombotic agents. One of the important product of endothelial cells, prostaglandin I2 or prostacyclin (PGI2) helps to maintain hemostasis through its involvement in coagulation, platelet activation, leukocyte migration and adhesion, vascular tone regulation and growth control. PGI2 synthesis is a readily quantifiable index of endothelial cell perturbation and thus serves as a marker for the identification of injurious stimuli. Endothelial cells were isolated from human umbilical vein and cultured in M-199 medium plus 20% fetal calf serum. Purity of culture was determined by immunological fluorescent staining of factor VIII related antigen, phase-contrast microscopy. TRK 790 radio-immunoassay kit was used for the measuring of 6-keto-PGF1 alpha released by endothelial cells. The results were as follows: 1) The concentration of PGI(2) released from the cultured endothelial cells was 33.44 +/- 2.26 pg/1 105 cells/mL 2) Incubation of endothelial cells with anoxia and reoxygenation resulted in PGI(2) release of 42.98 +/- 2.29 pg/1x10(5) cells/ml and 62.44 2.11 pg/1 105 cells/ml, respectively. 3) Incubation of endothelial cells with allopurinol (20 mumol/L) decreased the PGI(2) release to 40.68 +/- 2.99 pg/1x10(5) cells/ml. In conclusion, our data showed that the damage of endothelial cells in reoxygenotion group was significantly increased comparing anoxia group (p<0.005) and that allopurinol can inhibit reoxygenation-induced injury of endotheial cells.
