The purposes of this study were to investigate the effects of drug use & the health-related habits(alcohol drinking, smoking and exercise) on the nutritional status of elderly. subjects were 362 free-living elderly aged over 65(male 131, female 231) in Chungbuk area. Interviews with questionaire on drug use, health-related habits, and nutrient intakes, anthropometric measurement and biochemical blood test were carried out from August to October in 1996. Energy intakes of the males who used drug were lower than those of males who did not use any drug, while energy intakes of the females who used drug were higher than those of females who did not. In biochemical indices, LDL-cholesterol level of the males who used drug was higher than that of males who did not have drug. serum triglycerides, VLDL-cholesterol and obesity degree(BMI & TS) of the females who used drug were higher than those of females who did not have drug. Alcohol drinking, smoking and exercise habits of the elderly who used drug had little effects on the nutrient intakes while those habits had considerable effects on biochemical indices and obesity degree. Among drug users, male drinkers showed higher triglycerides & HDL-cholesterol level, and female drinkers showed higher triglycerides and lower total cholesterol and LDL-cholesterol level, compared to non drinkers. Among female drug users, smokers showed lower body mass index(BMI) compared to non smokers. Males and females who had both drinking and smoking habits showed higher serum triglycerides and VLDL-cholesterol level. Especially females who had both drinking and smoking habits showed lower BMI & Tricep skinfold thickness compared to those who had netiher drinking nor smoking habits.

Patients with chronic renal failure, many of which treated with hemodialysis, present a high prevalence of impaired muscle strength which suggest that muscle mass parameters may be used as markers for changes in muscle in these patients. Measurement of handgrip strength (HGS) is a common, simple, and quick measure of muscle function an indicator of overall muscle strength which has been associated with physical activity and several anthropometric traits. Intercellular adhesion molecule-1 (ICAM-1) and insulin-like growth factor-1 (IGF-1) are biochemical markers associated with inflammatory processes which are a common consequence of dialysis. Additionally, hemodialysis patients frequently present signs of malnutrition and depression. This cross-sectional study aimed to evaluate if muscle and biochemical markers could be used to predict the risk of depression in hemodialysis patients. Several anthropometric parameters, nutrient intake, depression state and the serum levels of ICAM-1 and IGF-1 were determined and Pearson's correlation coefficient and/or Spearman's correlation coefficient were used to test the correlation between them. Our results do not show a correlation between HGF, IGF-1 and ICAM-1 with the depression status of the patients, but mid-arm muscle circumference (MAMC) was statistically and positively correlated with depression. Additionally, ICAM-1 levels were negatively correlated with HGS, MAMC, and IGF-1. Overall, the results of the present study suggest that HGS may be used as an indicator of cardiovascular diseases and MAMC may be a good predictor of the level of depression in hemodialysis patients, although further studies are required.

In studies on Erysipelothrix rhusiopathiae infection of pigs, a series of investigations were conducted for isolation, biochemical properties, pathogenicity, serotyping and susceptibility to antimicrobial agents. The results could be summarized as follows: 1. A total of 14 isolates of E rhusiopathiae were made from an acute form of swine erysipelas and the incidence was high during the hot summer season. 2. The biochemical properties of the 14 isolates were identical to the reference strain of E rhusiopathiae. 3. Pathogenicity of the isolated strain(89368) were ascertained that $LD_{50}$ for mice was $1.8{\times}10 $ cfu and also typical urticarious lesions and acute septicemia for pigs were induced by intradermal and intravenous inoculation with isolates, respectively. 4. All isolates were serotyped by the agarose gel slide double-diffusion system and proved to be serotype 1. 5. In susceptibility test to antimicrobial agents, 14 isolates of E rhusiopathiae were highly sensitive to ampicillin, baytril, cephalothin, chloramphenicol, penicillin and tetracycline.

These studies were carried out to survey the genetic contamination of six inbred mice (A, BALB/c, C3H, C57BL/6, CBA and KK) produced and supplied from the conventional breeding unit for improving the quality of mice as experimental animal. We examined alleles of five loci (Akp-1, Car-2, Hbb, Es-1 and Trf) by the use of biochemical markers with celluose acetate electrophoresis. As the results of test, BALB/c, A, C3H, C57BL/6, CBA and KK showed standard alleles in Akp-1, Car-2 and Hbb. But Es-1 of A and C57BL/6 and Trf of A, C3H, C57BL/6 and CBA did allelic divergence in loci. These results suggest that the colonies of A, C3H, C57BL/6 and CBA were genetically contaminated. Therefore, we recommend to eliminate the genetically contaminated mice thoroughly, to check on genetic monitoring regularly and to consider a counterpaln for improving the quality control as soon as possible.

Aim : To evaluate the pharmaceutical safety of the herbal formula Myelophil, composed of Astragali Radix and Salviae Radix, via systemic subacute toxicological study using SD rats. Methods : Forty male and 40 female SD rats were fed with Myelophil (5000, 2500 or 1250 mg/10 mL/kg) or distilled water for four weeks. Adverse effects were examined intensively by comparing the differences between normal and drug-administered groups using clinical signs, necropsies, histopathologic findings, hematology, urinalysis, and blood biochemical analysis. Results : No altered clinical symptoms including body weight, diarrhea, anorexia, death, and abnormal necropsy of major organs were observed in male or female rats. No drug-induced abnormalities in histopathological finding, hematological values, urinalysis, and blood biochemical values were found at any doses of Myelophil. Conclusion : Myelophil should be very safe when used in a clinical application with a wide therapeutic index.

The study subjects included the workers who were estimated to have been exposed in a low density of lead-laden glaze from pottery manufacturers. They were evaluated in terms of PbB and PbU as indices of lead concentration in the body, and Hb, Hct, ALAD, and FEP as indices of biochemical lead poisoning. Consequently, the study results revealed the relationship between each of indices and its effectiveness to indicate the degree of occupational lead exposure. 1. The mean of PbB was $22.85{\;}{\mu}g/d{\ell}$(range; $4.2~44.7{\;}{\mu}g/d{\ell}$) and PbU $45.69{\mu}g/d{\ell}$(range; $6.7~87.5{\mu}g/d{\ell}$), to indicate the level of lead exposure in the subjects. 2. While there was a high, linear correlation between PbB, PbU and FEP (r=0.835, r=0.855, respectively), a low correlation existed between PbB and ALAD(r=-0.240). 3. While there was a high, linear correlation between PbU and FEP(r=0.825), a low correlation existed between PbU and ALAD(r=-0.352). The above results suggest that FEP can be used as a highly useful biochemical index of lead poisoning, based on its high correlation with PbB and PbU indicating lead concentration in the body.

Biochemical characteristics of Spodoptera uigua nuclear polyhedrosis virus (SeNPV) isolated in Jinju were studied. SeNPV contained a number of nucleocapsids within a viral envelope embeded in polyhedra. The polyhedral protein of SeNPV was composed of a single polypeptide with a M. W. of 30kd. Double-immunodiffusion test showed that the polyhedral protein of SeNPV had common antigenic determinants with SINPV and BmNPV. Virion proteins of SeNPV were resolved into 49 polypeptides by silver staining after SDS-PAGE. The approximate genome size of SeNPV by restriction endonuclease analysis was 1l0kb.

Purpose: This study was done to identify correlates and variables predicting daily activity among elders with Diabetes Mellitus (DM). Methods: Seventy-six elders registered in the Department of Endocrine Medicine at C university hospital participated in data collection. Data on daily activity and biochemical variables were collected via actigraph accelerator (Actical) and blood tests between September 2009 and July 2010. Data analysis was done using SPSS WIN 15.0 program and included one-way ANOVA, independent t-test, Pearson correlation coefficients, and stepwise multiple regression. Results: This study showed a positive correlation between daily activity and High Density Lipoprotein Cholesterol (HDL-C) and a negative correlation among Total Cholesterol (TC), Triglyceride (TG), and Low Density Lipoprotein Cholesterol (LDL-C). The variables predicting daily activity were frequency of exercise, HDL-C, and TC. These factors accounted for 40.0% of the variance of daily activity in elders with DM. Conclusion: The results indicate that it is necessary to improve daily activity to reduce Fasting Blood Glucose (FBG), TC, and TG in elders with DM.

Poly(ADP-ribose)polymerase-1 (PARP-1) is a nuclear enzyme involved in various physical functions related to genomic repair, and PARP inhibitors have therapeutic application in a variety of neurological diseases. Docking and the QSAR (quantitative structure-activity relationships) studies for 52 PARP-1 inhibitors were conducted using FlexX algorithm, comparative molecular field analysis (CoMFA), and hologram quantitative structure-activity relationship analysis (HQSAR). The resultant FlexX model showed a reasonable correlation (r$^{2}$ = 0.701) between predicted activity and observed activity. Partial least squares analysis produced statistically significant models with q$^{2}$ values of 0.795 (SDEP=0.690, r$^{2}$=0.940, s=0.367) and 0.796 (SDEP=0.678, r$^{2}$ = 0.919, s=0.427) for CoMFA and HQSAR, respectively. The models for the entire inhibitor set were validated by prediction test and scrambling in both QSAR methods. In this work, combination of docking, CoMFA with 3D descriptors and HQSAR based on molecular fragments provided an improved understanding in the interaction between the inhibitors and the PARP. This can be utilized for virtual screening to design novel PARP-1 inhibitors.
