Microbiology 1992;0(01):-
The anti-tumor activity of fermentation and the ethanol extraction of ten Polyprous fungi against human lung cancer cell NCI-H460 were determined by MTr method,the effect of medium and time for cultivation on the anti-tumor activity were studied.The results showed that the fermentation liquid of Onnia tomentosa and Ceizene unicolon and the mycelium ethanol extract of Formitopsis pinicola had obvious an- ti-tumor activity,the tumor inhibiting ratio of mycelium ethanol extract of Formitopsis pinicola cultivated in Potato-woodehipping medium was 88.87% at the concentration for 500?g/mL,and the inhibiting ratio had little change when Formitopsis pinicola cultivated in different medi- um and for different days.
2.Issues on the Eligibility Management System in Medical Aid.
Journal of the Korean Medical Association 2007;50(10):856-858
The Ministry of Health and Welfare introduced a new reimbursement system called the Eligibility Management System in Medical Aid in July 2007. The operation of this system is interlocked with patient care programs of medical institutions. The new system was expected to realize effective management of the eligibility of beneficiaries by interactive communications between medical institutions and the National Health Insurance Corporation (NHIC) and thereby improve financial stabilization of the reimbursement system and optimize healthcare practices by preventing moral hazards in the relationship between beneficiaries and medical institutions. For the effective operation of this system, however, several drawbacks need to be resolved; firstly, one can currently use the system only through the internet, secondly, there is a legal issue that medical institutions are the subject of the management of eligibility, and lastly, healthcare information needs to be transferred to NHIC in a real-time manner. Particularly the last one needs a special attention because it can raise critical concerns of potential violation of human rights of patients and unnecessary regulations of medical practices.

This study was conducted to analyze the relations among nutritional knowledge, nutritional attitude eating practice and total nutritional diagnosis and also to find the influencing factors of them. The survey was done during the period from April 1990 to June 1990 and the target population were Ewha Woman's University students (freshmen and senior) of whom 1,354 peoples were surveyed. The summarized results are as follows ; 1. For the learning environment, the percentage of completion on nutritional knowledge course was 28.6% and among them the department of foods and nutrition had the highest score(100.0%) and the next was dept. of medicine(53.4%). 2. To find the relation which the nutritional knowledge, nutritional attitude, eating practice and the total nutritional diagnosis influence on one another, the multiple correlation analysis was done. The attitude the practice were highly correlated with total nutritional diagnosis, but the correlation between nutritional knowledge and total nutritional diagnosis was not significant. The correlation between the practice and nutritional knowledge which were positively and significantly correlated with attitude respectively was positive but not significant. 3. The difference which were analyzed by department, grade and completion on knowledge course on the nutritional knowledge, attitude, eating practice were significant (p<0.01) by ANOVA. 4. The significant variables on nutritional diagnosis are the eating practice points, the grade, the knowledge course, the breakfast and the attitude (r2=10.3%) by multiple regression analysis. This study has the limitation that it did not consider the environmental factors of dietary life such as dietary culture, family environment, cultural habit. Therefore important points of these dietary studies are to extend to the practical nutritional education and dietary improvement for the national health not restricted to the local area or local population.

Objective To study the inhibitive effect and mechanism of PPAR?1 on the extracellular matrix (ECM) accumulation of mesangial cells induced by Ang Ⅱ .Methods The plasmid of PPAR?1/WT (wild type) was transfected into mesangial cells. After 48 hours of Ang Ⅱ stimulation, the gene expression of TGF-?1, PAI-1, c-fos and c-jun was examined by RT-PCR. Protein levels of p-ERK, I-?B and nucleus/cytosol ratio of NF-?B were estimated by Westen-blot. The concentrations of FN and TGF-?1 were estimated by ELISA. The activity of PPAR?1 was examined by specific PPRE binding activity. Plasmid expressing non-functional dominant negative type of mPPAR?1, pIRES2-EGFP-mPPAR?1/DN (DN), and blank plasmid, pIRES2-EGFP (Blank) were used as controls. Effects of 6 ?mol/L PPAR? agonist pioglitazone (Pio) were also studied. Results The expression of TGF-?1 and PAI-1 mRNA in mesangial cells induced by Ang Ⅱ was inhibited by PPAR?1(P

0 05).Among them,WT but neither DN, Blank, nor Pio significantly ameliorated the increased concentrations of TGF-a1 and fibro nectin in culture medium induced by HG. Compared with DN and Blank, WT transfect ion significantly attenuated high glucose-caused elevation in c-fos, c-jun and p-ERK expression, reduction in Ⅰ-?B level, and incretio n in nucleus/cytosol ratio of NF-?B, while Pio demonstrated similarly signific ant changes only in p-ERK and NF-?B. No significant difference of GLUT-1 mRN A level was detected between HG groups. Conclusions Overexpressed PPAR?1 can su ppress increased ECM production from glomerular mesangial cells cultured in HG c ondition. Its inhibitory effects on activation of ERK/AP-1 and NF-?B pathways are involved. The further increase of PPAR?activity may have direct anti-fibr otic effect in diabetic kidney.

Canalith repositioning maneuver is effective to treat benign paroxysmal positional vertigo(BPPV). This case showed complicated form of the BPPV such as changes of canalolithiasis to cupulolithiasis, involvement of one canal to two canals and from unilateral to bilateral involvement during the reposition maneuver. This patient was diagnosed as left lateral canalolithiasis at first. After left barbecue maneuver, the type was changed to the right posterior cupulolithiasis. Semont maneuver was performed and then the type of BPPV was changed to combined type with right posterior canalolithiasis and left lateral canalolithiasis. We performed left barbecue maneuver and right Epley maneuver. Then the type of BPPV was changed to left lateral cupulolithiasis. After Brandt-Daroff maneuver and left barbecue maneuver, nystagmus and dizziness disappeared finally.

BACKGROUND: The central physiological derangement of hemorrhagic fever with renal syndrome (HFRS) caused by hantaan virus (HTNV) is a vascular dysfunction, manifested by hemorrhage, impaired vascular tone and increased vascular permeability. Platelet activating factor (PAF), whose actions are mediated through a specific receptor, is a potent bioactive lipid. PAF has diverse biological functions in the vascular system, such as increasing vascular permeability, adhesion of leukocytes to the endothelium and reduction of cardiac output, which result in hypotension and shock. The goal of the present study was to investigate whether PAF is involved in the pathogenesis of HFRS. For this purpose, we evaluated the effect of HTNV on the expression of PAF receptor (PAF-R) and on the activity of PAF-acetylhydrolase (PAF-AH) instead of PAF because PAF is rapidly degraded by PAF-AH in vivo. MATERIALS AND METHODS: To evaluate the expression of PAF-R, we performed reverse-transcription PCR, western blot and FACS analyses using HTNV-infected human umbilical vein endothelial cells (HUVECs) and non-infected (control) HUVECs. In addition, we measured the activity of plasma PAF-AH in HFRS patients and normal healthy persons. RESULTS: The mRNA and protein expression of PAF-R was increased in HTNV-infected HUVECs compared with control HUVECs at 2 and 3 days post-infection (d.p.i.). FACS analysis showed that HTNV induced the surface expression of PAF-R in HUVECs from 2 d.p.i. The activity of plasma PAF-AH was 2.5-fold lower in HFRS patients than in normal healthy persons. CONCLUSION: Increased PAF-R expression by HTNV might increase the responsiveness to PAF in endothelial cells. Reduced PAF-AH activity in the blood of HFRS patients might delay PAF degradation. These results suggest that changes in PAF-R and PAF-AH by HTNV might influence to PAF activity and might be involved in the vascular dysfunction of HFRS.
