To elucidate the effect of exercise on blood concentrations of ethanol, lactate and glucose in men who show facial flush after ethanol ingestion, 59 healthy male college students were studied. After 6 or more hours of fasting, the subjects were administered 3 ml of 25% ethanol solution(Soju) per liter of total body water. For control experiment Soju was replaced with the same dose of water. Exercise performed was vertical jumping on a rebounder for 3 min immediately after drinking. The subjects were classified into 6 groups: water ingestion(W), flushed (F) and non-flushed (N) groups after ethanol ingestion, water ingestion and exercise(WE), flushed(FE) and non-flushed (NE) groups after ethanol ingestion and exercise. Blood ethanol concentration in the exercise groups(NE, FE) was lower until 60 min after drinking than that in the non-exercise groups(N,F). Factor k representing the rate of ethanol absorption was markedly lower in the exercise groups than in the non-exercise groups. The flushed groups(F,FE) showed higher blood ethanol level than the non-flushed groups (N,NE) from 30 to 120 min after drinking. Blood lactate concentration in WE group was elevated immediately after exercise and returned to the resting level at 60 min after exercise. Ethanol increased blood lactate level from 30 to 120 min after ethanol drinking, Exercise after ethanol ingestion produced a sharp increase and then drop in blood lactate level which was stilled significantly higher than the resting level all the way through 120 min. Blood glucose concentration was decreased at 15 min after exercise. Ethanol-administered groups except F group showed a steady decrease in blood glucose level from 30 through 120 min. Heart rate was elevated by ethanol only in the flushed groups. Heart rate in F group was significantly increased at 4 min after ethanol and was maintained at high level until 120 min. In WE and NE groups, heart rate was significantly increased immediately after exercise and returned to the resting level at 60 min. The FE group, however, showed a consistently elevated heart rate throughout the 120-min experimental period. Taken together, the exercise alone produced a delayed ethanol absorption, a prompt increase in heart rate and blood lactate level and a decrease in blood glucose level early in the recovery period from exercise. After ethanol administration, blood lactate was elevated and blood glucose was lowered from 30 to 120 min. Flushed subjects showed rapid increase in heart rate after ethanol drinking and higher blood ethanol level than non-flushed ones from 30 to 120 min after drinking.

The aim of this study was to improve the efficacy and functionality of Viola mandshurica (VM). A water suspension of VM power was fermented for 72 hr with Bacillus methylotrophicus CBMB205 (BM) and Leuconostoc pseudomesenteroides NRIC1777 (LP) isolated from kimchi. The antioxidant activity and reducing power of fermented VM, its total phenolic and flavonoid compounds, as well its inhibitory activity on ${\alpha}$-amylase, ${\alpha}$-glucosidase, and pancreatic lipase were determined and compared to those of non-fermented VM (NVM), a negative control. The total phenolic and flavonoid compounds of VM fermented with BM and LP were higher than those of NVM by 1.4, 1.17, and about 3 times. There was no difference in 2, 2'-diphenyl-1-picryl hydrazyl (DPPH) radical scavenging activity between fermented VM and NVM. However, there was a 2.1- and 1.6-fold increase in 2, 2'-azino-bis-(3-ethylbenzothzoline-6-sulfonic acid) (ABTS) radical scavenging activity in VM fermented with BM and LP, respectively. The reducing power of BM was 1.6 times as high as NVM, but no significant difference was found between LP and NVM. Fermented VM's inhibitory activity on ${\alpha}$-amylase, ${\alpha}$-glucosidase, and pancreatic lipase was much higher than that of NVM. Fermenting VM with BM was superior to fermenting it with LP, except flavonoid content. Taken together, VM fermented with BM could be used as a functional food and as an additive to cosmetics.

Purpose: Pregnancy in transplanted mother is considered as a high-risk pregnancy, and significant incidences of prematurity and low-birthweight(LBW) infants have been reported. The objective of this study is to examine the outcome of pregnancy in transplanted mothers and to evaluate the current growth status in their children. Patients and Methods: We retrospectively reviewed 54 pregnancies in 40 kidney recipients until June 1999. Outcomes of pregnancy were reviewed and assessment of the current growth status in children was performed. Results: 54 pregnancies in 40 recipients were identified; 22 ended in termination of pregnancy because of unwanted pregnancy or therapeutic purposes. And of the other 32, 29 livebirths resulted in 28 recipients. The mean age of conception was $30.3{\pm}3.8$ years, with a mean interval from transplantation to conception of $35.9{\pm}23.2$ months. All patients were maintained on immunosuppressive regimens. Incidence of drug-treated hypertension(HTN) prior to pregancy was $52\%$, HTN during pregnancy, $48\%$; preeclampsia, $41\%$; urinary tract infection, $48\%$; oligohydramnios $4\%$; and no rejection during pregnancy and up to 3month post delivery. Of the 29 liveborn infants, prematurity(<37wk) occurred in $52\%$, LBW(<2500g) in $62\%$, VLBW(<1500g) in $7\%$ and $48\%$ born intrauterine growth retardation(IUGR). Mean gestational age was $36.3{\pm}3.0\;wk$; a mean birthweight, $2.23{\pm}0.6\;kg$; a mean birth-height, $45.1{\pm}3.6cm$. Current mean height standard deviation score (height SDS) was $0.29{\pm}0.91$ and mean weight SDS was $0.62{\pm}1.34$. Only one child($4\%$) under 1 year of age was below 10 percentile in height. Most of children had no medical problems except for 4 children; cleft palate(1), tuberous sclerosis(1), essential hematuria(1), and one child expired due to sepsis. Conclusion: This study showed similar incidence of premaure birth($57\%$) and low birth weight infants($62\%$), but lower incidence of spontaneous abortion($5.6\%$) was observed and compared to other studies. Postnatal growth in majority of children($96\%$) achieved catch-up growth before 1 year. Present study supports a more optimistic view of pregnancy in renal transplant mother and normal growth in their children.

Cleft lip and/or palate(CLP) is the most common congenital deformity in the craniofacial region. For a practical public health system for these patients it is necessary to have an understanding on the prevalence of CLP. However, it was difficult to estimate the exact number of CLP patients due to problems in sample selection, higher miscarriage and still birth rate, difficulty in classification, and adoptions to foreign countries. Therefore this study was to estimate the prevalence of CLP and the rate of orthodontic treatment, which is usually necessary in cleft lip and/or palate patients. The samples consisted of 218,322 Korean male adults from Seoul, Kwangju, Taegu and Pusan, all born in 1979. The screening method for recognizing the CLP patients was proceeded in steps and the results are as follows. 1. The prevalence of cleft lip and/or palate in Korean male adults born in 1979 was 0.65 out of the 1000 samples. 2. In the anteroposterior aspect of the 1000 samples, the prevalence of cleft lip, cleft lip and palate, and cleft palate was 0.26, 0.36 and 0.03 respectively. 3. In the transverse aspect of the 1000 samples, the prevalence of left, right and bilateral cleft was 0.35, 0.16, 0.12 respectively. The cleft in the left showed a much higher prevalence than in the rirht, while bilateral cleft showed a lower prevalence than unilateral cleft. 4. The orthodontic treatment rate of Korean male adults among cleft lip and/or palate Patients was $35\%$, and it was in the order of cleft lip and Palate, cleft lip, and cleft Palate, being $67\%,\;29\%\;and\;29\%$ respectively. The orthodontic treatment rate in patients with the more severe cleft lip and palate was higher than in patients solely having cleft lip or cleft palate.

This study was conducted to estimate the prevalence rate of cervical cancer and to investigate its risk factors. 5,417 asymptomatic married women were screened from March, 1984 to December, 1990 in Taegu city. Of 5,417 examinees, 3,817 (70.46%) were normal, 1,542 (28.7%) showed inflammatory change, 51 (0.94%) were dysplasia and 7 (0.13%) were carcinoma in situ or invasive carcinomas. The prevalence of abnormal finding (dysplasia, carcinoma in situ or invasive carcinoma) was 1,070 per 100,000 population. The prevalence of dysplasia was 940 per 100,000 and that of carcinoma in situ or invasive carcinoma was 130 per 100,000. Age-adjusted prevalence rate for abnormal finding adjusted with standard population of Taegu city was estimated to be 850 per 100,000. The prevalence of cervical cancer was significantly increased with age (P<0.05). The prevalence of cervical cancer was significantly decreased with age at marriage and educational level (P<0.05). The history of induced abortion and the number of pregnancies were significantly associated with the prevalence of cervical cancer (p<0.05), whereas, the number of parity was not. Age at marriage was significantly associated with the prevalence of cervical cancer after stratification by age (p<0.05). However, the level of education, parity, induced abortion, number of pregnancies were not significant. Inflammation and human papiloma virus infection were associated with cervical cancer with odds ratio of 13.48 (95% confidence interval $7.80{\sim}23.40$) and 474.29 (95% confidence interval $196.80{\sim}1143.10$), respectively. In conclusion, for early detection of cervical cancer it should be recommended to perform mass cytological screening. In particular, regular and periodic cytologic screening, starting at age 25, for cervical cancer should be recommended for those women who have frequent cervical inflammation and for those women married before age of 20.

An in situ ruminal disappearance trial and an in vivo sheep metabolism trial were conducted to evaluate the nutritional value of spent mushroom substrate (SMS, originated from Pleurotus osteratus bed-type cultivation). The raw SMS was ensiled (ESMS) for 30 days with 5% (w/w, DM basis) molasses, 0.5% (v/w) yeast (Saccharomyces cerevisiae) and 0.5% (v/w) lactic acid bacteria (Lactobacillus plantarum). Two ruminally cannulated Holsteins (average BW 620 kg) were used to evaluate in situ disappearance. Six sheeps (average BW 48 kg) were fed, in $3{\times}3$ Latin square design, rice straw alone (Control), 25% (ESMS-25) and 50% (ESMS-50) of rice straw were replaced with ensiled SMS. For an in situ trial, ruminal DM and neutral detergent fiber (NDF) disappearance of SMS were increased after ensiling (P<0.05). For a sheep trial, protein and fiber (NDF, acid detergent fiber, crude fiber) digestibilities were decreased (P<0.05), crude ash digestibility was increased (P<0.001), and nitrogen retention was not affected (P>0.05) as rice straw was replaced with ensiled SMS. Ruminating time was decreased by an average of 28% by feeding ensiled SMS (P<0.05). Ensiled SMS (Bed-type cultivation) had 76% of energy value of rice straw. Consequently, ensiled SMS (Bed-type cultivation, 100% cotton waste) could be used as a roughage source appropriate for maintenance type rations for ruminants.

Gastric acid resistance of aerobic Lactobacilli and anaerobic Bifidohacteria in commercial 19 drink and 18 liquid yogurts in Korea was investigated after exposure to simulated gastric fluid (pH 1.5). The initial survival of Lactobacilli in commercial drink and liquid yogurts was $10^8~10^{10}$ cfulml and $10^6~10^{10}$cfdml, respectively. On the other hand, the initial survival of Bifidobacteria in commercial drink yogurts was ($10^6~10^{10}$cfulml. The survival of Lactobacilli and Bifidobacteria in some commercial drink and liquid yogurts drastically changed depending on the type of commercial products when exposed to simulated gastric fluid for 120 min (<$10^3~10^6$ cfulml). Their survival decreased as a function of time in the simulated gastric fluid. In the case of drink yogurt containing Bifidobacteria-loaded capsu1es;the survival of Bifidobactena in only Mi after excluding capsules was similar to other commercial drink yogurts after exposure to gastric fluid for 30-120 min (ca. TEX>$10^5$ cfulml). However, the survival of Bifidobacteria in capsules was greatly enhanced due to their stability in low pH condition (>$10^8$ cfulml). The drink yogut containing Bifidobacteria-loaded capsules showed about 10-737 times higher survival in the gastric fluid for 120 min when compared to other commercial drink yogurts. It was evident that the gastric acid resistance of Bifidobacteria could be increased when encapsulated.

The study on leptospiral infection among cows was carried out to find out possible role of this domestic animal as an infection source for humans, and the magnitude of economic loss due to abortions caused by leptospiral infections among the domestic animal. Bood samples of 459 cows in May and 446 heads in November 1989 were collected from 19 villages of Kyunggi Province. These samples were cultured and serologically tested. Only one strain of leptospires, most strongly reactive to Pomona antibody, was isolated from duplicated cultures of 985 cow blood samples in EMJH medium. Serological test by MAT with seven reference strains and three locally isolated strains was positive in 12% of the sample in May and 26% in November ; positive rate increased slightly as the age of cows increased and male cows had higher positive rate, however, there was on difference in positive rate by type of cow and area. There was no statistically significant association between abortion history among cows(one yearperiod) and positive MAT. Thus it was concluded that the leptospiral infection of cows may play a role for human infection, and the leptospiral infection of cow may not be the major cause of abortion although further study is necessary for definite conclusion.

Acetylsalicylic acid (ASA)와 고려홍삼의 항산화 성분인 maltol을 축합하여 신물질 aspalatone을 합성하고, 흰쥐에서의 지혈시간 연장 효과, 항혈소판 응집 억제 (in Vitro, ex ViVO) 효과 및 생쥐의 혈전 모델을 이용한 항혈전 (in vivo) 효과를 연구하였다. SD계 웅성 흰쥐에 15 mg/kg의 낮은 용량으로 경구투여 할 경우, aspalatone과 ASA는 각각 최소한 8일 연속투여후 지혈시간을 유의적으로 연장시켰으며 같은 용량으로 10일 간 경구투여. 하였을 때, aspalatone 투여군은 대조군에 비하여 지혈시간이 57% (p<0.005) 연장된 반면, ASA 투여군은 44% 연장되었다. 반면, aspalatone의 아세칠 기를 갖지 않는 salicylic acid maltnl ester는 같은 용량에서 지혈시간을 유의적으로 연장시키지 않았다. Aspalatone은 in vitro에서 collagen에 의해 유도된 흰쥐 혈소판 응집을 강력하게 억제하였으나 (IS$_{50}$ = 0.18 mM), ASA와 마찬가지로 ADP에 의한 응집은 억제하지 않았다. Aspalatnne과 다른 대조약물들의 ex vivo에서의 혈소판 응집 억제능은 ASA>dipyridamdle(equation omitted)aspalatone>ticlopidine의 순이었다. 1회 경구투여로 aspalatone은 생쥐의 collagen에 의한 혈전에 기인하는 치사율을 억제하였다 (ED$_{50}$ = 32mg/kg). Aspalatone을 10일 간 투여하면 유효용량이 현저히 감소하여 20 mg/kg에서 치사율을 90% (p<0.001) 억제하였으며, 이러한 항혈전 효과는 투여중단 4일 후에도 지속되었다. 또한, 경구투여시 위궤양을 유발하는 ASA (ulcer index : 29 mm 200 mg/kg p.o.)와는 다르게 aspalatone은 위궤양을 유발하지 않는다는 장점을 갖는다 (0.71 mm, 800 mg/kg p.o.). In vitro에서 malondialdehyde 생성 억제를 지표로 한 aspalatone의 항산화 활성 ($IC_{50}$/ = 0.11 mM)은 maltol ($IC_{50}$/ = 0.084 mM)과 유산하다. 이러한 실험결과를 토대로 하여 aspalatone을 위궤양을 유발하지 않는 항혈전 신약으로 개발하기 위한 연구가 진행 중이다.

A microbial strain capable of producing lactic acid was isolated and identified as Streptococcus faecium. During the incubation of the isolated bacterium in a synthetic medium (Petterson broth), the optimal temperature was 36 to 39$^{\circ}C$ and the cell concentration at stationary growth phase was 2.1${\times}$10$\^$8/ viable cells/ml. When it was dried in vacuum and diluted with avicel, the Viability of Streptococcus faecium in physiological saline solution was decreased to 80％ after incubation for 48 hr at 37$^{\circ}C$, whereas the viability was above 90％ after incubation for 1 hr at 40$^{\circ}C$ and the viability in M buffer solution (pH 4.5∼9.0) at 37$^{\circ}C$ was above 95％. From these data it was concluded that the isolated microbe must be adoptible for pharmaceutical preparation such as solid dosage form.
