In a previous study, we developed a new food additive as an egg yolk antibody (IgY) against carbohydrate digestion enzymes for the regulation of blood glucose level and weight control. The IgY delayed and decreased the increment of blood glucose level after administration of sucrose in human being by 30% in 20∼30 min. We also developed a lipase inhibitor as a water extract of two kinds of herb, Platycodon grandiflorum and Solanum melongena. Twenty three volunteers were subjected to the intake of the egg yolk IgY plus the herbal extracts for 50 days. In average, the treated subjects appeared to lose 1.96 ㎏ of body weight and 3.4 ㎏ of body fat mass during the treated period. Furthermore, Panniculus adiposus and breech size were significantly decreased during the experimental period. Above results suggested that the administration of the dietary additives composed of egg yolk IgY and natural herbal extract improve the obesity by the decrement of body weight and body fat mass.

Fire characteristics of a typical apartment building in Korea was studied through full scale experiment and zone model simulation. The fire was ignited at the living room and allowed to spread to other parts of a single unit in a five storied apartment building. Various data including temperatures, species concentrations, and images were collected in the experiment. A zone model(CFAST) was used to analyze the same apartment building that represents the average households in Korea. The results were compared with a full scale experiments. While CFAST allows one compartment involved with fire, the experiment allowed the fire to spread to other compartments. Therefore, the comparison between experimental data and Zone-Model data is valid until the living-room fire spread to other parts of the apartment. Flashover occurred at approximately 380 seconds in a fire experiment, and at approximately 420 seconds in Zone-Model. Based on all of data between experimental data and Zone-Model data, it is concluded that the safe escape time is about 250 seconds.

Cimetidine is a histamine H₂-receptor antagonist, used for the treatment of endoscopically or radiographically comfirmed duodenal ulcer. pathologic GI hypersecretory conditions. and active, benign and gastric ulcer. Simple method for determining cimetidine in human plasma has been developed and validated. The analytical procedure for cimetidine showed a linear relationship in the concentration ranges from 0.05 to 5 pg/ml. Coefficient of variance (CV, ° o) for intraday and interdav validation and relative error (RE. ° o) were less than ±150 o. Based on this analytical method. the bioequivalence of two cimetidine 400 mg tablets, reference (Tagamet 400 mg) and test drug (Sinil CIMETIDINE 400 mg) was evaluated according to the guidelines set by the Korea Food and Drug Administration (KFDA). Release of cimetidine from the tablets in vitro was tested using KP VIII Apparatus II with various dissolution media (pH 1.2. 4.0. 6.8 butter solutions and water). Twenty-four healthy volunteers. 21.38±1.86 years in age and 68.71±8.68 kg in bode weight, were divided into two groups and a randomized 2x2 cross-over study was performed. After oral administration of a tablet containing 400 mg of cimetidine. blood samples were taken at predetermined time intervals and concentrations of cimetidine in plasma were determined using HPLC equipped with UV detector. The dissolution profiles of the two tablet formulations were very similar at all dissolution media. In addition. pharmacokinetic parameters such as AUC, and C_(max) were calculated and ANOVA was employed for the statistical analysis of parameters. The results were revealed that the diterences in AUCf and Cma, between the two tablets were 4.17% and 0.97% respectively. At 90% confidence intervals. the differences in these parameters were also within ± 20° o. All of the above mentioned parameters have met the criteria of KFDA guidelines for bioequivalence, indicating that the test drug tablet (Sinil CIMETIDINE tablet) is bioequivalent to Tagamet 400 mg tablet.

This study was performed to measure airborne dimethyl-formamide(DMF), methyl ethyl ketone(MEK) and toluene and their urinary metabolites concentrations and to determine the relationship between airborne and urinary concentration. Air-borne samples and their urinary metabolites were measured 98male workers who work for 8 synthetic leather factories in a portion of Kyoung-in area. Urine samples were collected at end-of-shift to estimate the exposure levels. 1. The concentration of airborne DMF by process was 8.81 ppm for wet-mixing, 15.05 ppm for wet-coating, 6.03 ppm for dry-mixing, 5.58 ppm for dry-coating, 5.37 ppm for printing, and 9.03 ppm for total. There was statistically significant difference by process. Urinary NMF concentrations of wet-mixing, Wet-coasting, Dry-mixing, dry-coating and printing were 90.55㎎/, 79.80㎎/ℓ, 39.86㎎/ℓ, 25.23㎎/ℓ, and 38.15㎎/ℓ, respec-tively, and total geometric mean was 56.24㎎/ℓ. There was statistically significant difference by process. 2. The concentration of airborne MEK by process was 1.89 ppm for wet-mixing, 1.96 ppm for wet-coating, 10.33 ppm for dry-mixing, 29.24 ppm for dry-coating, 14.98 ppm for printing, and 4.87 ppm for total. There was statistically significant difference by process. Urinary MEK concentrations of wet-mxing, wet-coating, dry-mixing, dry-coating and printing were 0.93㎎/ℓ, 0.70㎎/ℓ, 3.29㎎/ℓ, 3.29㎎/ℓ, and 1.06㎎/ℓ, res-pectively, and total geometric mean was 1.25㎎/ℓ, There was statistically significant difference by process. Urinary MEK 3.The concentration of airborne toluene by process was 0.35ppm for wet-mixing, 0.42ppm for wet-coating, 2.95ppm for dry-mixing, 11.67ppm for dry-coating, 4.88ppm for printing, 1.24ppm for total. There was statistically significant difference by process. Urinary hippuric acid concentrations of wet-mixing, wet-coating, dry-mixing, dry-coating and printing were 0.24g/g creatinine, 0.21g/g creatinine, 0.34g/g creatinine, 0.52g/g cre-atinine, and 0.29g/g creatinine, respctively and total geometric mean was 0.28g/g creatinine. There was statistically signifi-cant difference by process. 4. No. of exceeded KPEL was 40 workers(40.8%) for DMF(10ppm), 1 worker(1.0%) for MEK(200ppm), and no worker for toluene(100ppm). No. of exceeded KBEI was 62 workers(63.3%) for urinary NMF(40㎎/ℓ), 29 workers (29.6%) for uri-nary MEK, 1 worker(1.0%) for urinary hippuric acid. 5. The regression equations were Log(MMF)=0.4094* Log(DMF)+1.3587(r=0.4516) for DMF, Log(MEKU)=0.1859* Log(MEK)-0.0324(r=0.3303) for MEK, Log(HA)=0.2106* Log(Toluene)-0.5685 (r=4497) for toluene. Synthetic leather factory workers expose to 3 kinds of organic solvents which are DMF, MEK and toluene. Their Uri-nary NMF and MEK levels were higher than their concentration levels through respiratory. It seems that the urinary levels were affected skin absorption for working habit and alcohol intake.

Pefloxacin의 광분해에 관한 연구 Ⅰ

최윤수,석경순,이경선 대구효성가톨릭대학교 응용과학연구소 1994 응용과학연구논문집 Vol.3 No.-

We investigated the photodegradation of pefloxacin(PFX) in some conditions. Pefloxacin was decomposed by light with different patterns in several solvents-ethanol, methanol and water. In the neutral and alkaline the rate of photo-degradation was more rapid than in acidic. When oxygen was replaced to N_2 gas, we found that it prevent pefloxacin from photodegrada-tion. Using the singlet oxygen scavenges-sodium azide and α-tocopherol, we obtained an indica-tive evidence of that photo-degradation pathway is mediated by singlet oxygen.
