Allium tuberosum Rotter(Liliaceae) is a perennial herb of which leaves are used for food. Leek has been reported to have pharmacological effects including alleviations of abdominal pain, diarrhea, hematemesis, snakebite, and asthma. To investigate the effect of dietary leek supplementation on the drug-metaboizing enzymes, quinone reductase(QR) and arylhydrocarbon hydroxylase(AHH) activities in the liver, stomach, small intestine and lung, and on the plasma testosterone and dihydrosterone hormone levels, mice were fed 2% and 5% leek diets for 8 weeks. Quinone reductase, an anticarcinogenic enzyme, was significantly induced in stomach, small intestine, and lung but slightly lowered in hepatic tissue in the experimental groups compared to control group. Arylhydrocarbon hydroxylase activity, involved in bioactivation of procarcinogens, was significantly decreased in liver and lung. Leek feeding led to the reduction in the plasma level of dihydrotestosterone which is associated with the incidence of prostate cancer. These findings support the potential chemopreventive activity of leek supplementation.

Recombinant bioluminescent bacteria and cultured human cells were applied for toxicogenomic analysis of environmentally hazardous chemicals. Recombinant bioluminescent biosensing cells were used to detect and classify the toxicity caused by various chemicals. Classification of toxicity was realized based upon the chemicals' mode of action using DNA-, oxidative-, protein, and membrane-damage sensitive strains. As well, a simple double-layered cell culture system using Caco-2 cells and Hep G2 cells, which mimic the metabolic processes occurring in humans, such as adsorption through the small intestine and biotransformationin both the small intestine and the liver, was developed to investigate the toxicity of hazardous materials to humans. For a more in-depth analysis, a DNA microarray was used to study the transcriptional responses of Caco-2 and Hep G2 cells to benzo〔a〕pyrene.

왕종개 Iksookimia longicorpa의 공기호흡에 관한 호흡체계를 조사하기 위해 표피 (epidermis)와 소화관 (intestinal tract)를 관찰하였다. 표피는 작은 점액세포 (mucous cell)와 곤봉세포 (club cell)로 이루어진 두 종류의 선세포 (gland cell)을 가진다. 점액세포는 대부분 acid sulfomucin으로 구성되었으나 곤봉상세포는 점액물질에 대한 어떠한 반응도 보이지 않았다. 기저층에는 작은 림파구를 포함하는 lymphocytes가 존재하며, 다량의 모세혈관이 기저층 바로 아래부분에 존해하고 있다. 장( intestinal tract)은 거의 일직선형태이며, 크게 장(intestine)과 직장(rectum)으로 구성된다. 이러한 장은 점액층 (mucosa), 점막하층 (laminal propria-submucosa), 근육층 (musculary), 장막 (serosa) 층으로 구성되었다. 이러한 장은 짧은 fold와 얇은 벽으로 구성되었으며, 점막층은 acid sulfomucin의 점액을 가지고 있다. 공기호흡하는 어류들의 변형된 공기호흡 기관의 특징들과 비교해 볼 때 왕종개는 하천의 가뭄으로 인해 용존산소가 부족할 경우 장에서는 이루어지지않고 표피에서만 공기를 흡입하는 것으로 생각된다.

Objectives : Assuming that the characteristic of meridian system has been similar to this of electric potentials in human body and that measurements of electric potential at well(井穴) and sea(合穴) points in branches of the twelve meridians(WSBTM) will be representative of measurements of the twelve meridians, to measure the electric potentials of 13 patients with Arthroncus of Knee(슬안풍<膝眼風>, AK), to find out the characteristic of meridian system in patients with AK. Methods : Electric potentials of well and sea points in the meridians in twenty one patients with the pain in the lion diagnosed as AK were repeatedly measured by physiograph(PowerLab). Measurements of those electric potentials were analyzed by factor analysis. Results : Their electric potentials at the left and right side were factors which are different from each side. In the left side, Factor 1 included Small Intestine, Pericardium, Spleen, Kidney meridian, and Factor 2 included Heart, Tripple Energizer, Bladder, Liver meridian. Factor 3 included Large Intestine, Stomach, Gall bladder meridian, and Factor 4 included Lung meridian. In the right side, Factor 1 included Heart, Pericardium, Tripple Energizer, Spleen, Bladder meridian and Factor 2 included Lung, Liver, Gall bladder meridian. Factor 3 included Small Intestine, Stomach, Kidney meridian and Factor 4 included Large Intestine Meridian. Conclusions : The electric potentials of AK differ from those of normal bodies as well as of bodies with other diseases-shoulder lesions, waist lesions, Lumbago due to Strain and Contusion-. Thus electric potentials of well and sea points might be the representative meridian to show their characteristics.

Reported here are the effects of added formic acid on inhibitory effect of Salmonella gallinarum in poultry feed. Two experiments were conducted to investigate the viability of S. gallinarum and pH of poultry feed using different dietary formic acid levels (0.0, 0.5, 1.0 and 1.5%) on inhibitory effect of S. gallinarum in broiler feed. Experiment one was conducted to investigate the viability of S. gallinarum and pH of artificially contaminated diet at 0, 1, 3, 5 and 7 days after treatment in vitro. Formic acid showed a significant (p<0.05) reduction in the viability for all treatments with time after treatment. Various formic acid levels in vitro showed a reduction in the pH of the diet depending upon the concentration of treated acid, and the diet remained acidic below the growth range of S. gallinarum. This meant that the bacterial cells were exposed to stressful conditions that made them unable to grow. Experiment two was conducted to find out the effect of dietary formic acid levels on S. gallinarum colonization and pH in the contents of crop, small intestine, large intestine and ceca and mortality rate of broiler chicks at 7, 14 and 21 days of age when fed artificially contaminated diet with S. gallinarum. The numbers of S. gallinarum re-isolated from all treated groups except in groups treated with 0.5% formic acid, decreased significantly (p<0.05) compared with the control group. The treatment significantly (p<0.05) lowered the pH of the crop, small intestine, large intestine and ceca contents in all groups except the groups treated with 0.5% formic acid compared with the control. All treated groups showed a significant (p<0.05) reduction in overall mortality rate during the experimental period (3 to 21 days) compared with the control. The results indicate that addition of formic acid in a total concentration of 1.5% to the diet of newly hatched broiler chicks significantly decreases the contamination of diet with S. gallinarum.

Four Korean native steers ($511{\pm}17.2kg$; $2{\times}2$ replicated crossover design) fitted with duodenal cannulas were used to investigate the influence of oral administration of soluble whey protein (WP; 82.29% crude protein) on ruminal fermentation, gastrointestinal (GI) hormone secretion in the blood, pancreatic ${\alpha}$-amylase activity in the duodenum, and disappearance rate in each segment of the GI tract. Steers were orally fed the basal diet (control; TMR [total mixed ration] 9 kg/d) or the basal diet with enriched WP (400 g/d) for 14 days. The apparent crude protein disappearance rate in the rumen of the WP was higher than in control (p < 0.05). However, no difference between groups was observed in the apparent crude protein disappearance rate in the intestine and the apparent starch disappearance rates in the rumen, GI tract. The level of cholecystokinin, secretin, and ghrelin in serum and pancreatic ${\alpha}$-amylase activity in the duodenum of the WP also did not change. The changes in the level of blood urea nitrogen related to protein metabolism were higher in the WP than in the control (p < 0.05). However, the levels of total protein, lipid, carbohydrate and mineral metabolites did not change. Consequently, we suggest that the oral administration of WP in steers assisted in ruminal fermentation due to the population increase of microbes in the rumen but did not improve the starch digestion rate in the small intestine because GI hormone secretion in the blood and pancreatic ${\alpha}$-amylase activity did not change.

Objectives : While Comparative Pulse Diagnosis of Renying pulse(人迎脈) and Cunkou pulse(寸口脈) is one of the three major pulse diagnostic methods in "Huangdineijing" along with Three Positions and Nine Indicators Pulse Diagnosis(三部九候脈診法) and Cunkou Pulse Diagnosis(寸口脈診法), it has died out in later periods. This study aims to examine this lost method. Methods : Annotations of "Huangdineijing" were examined along with descriptions of the author's own experience. Results & Conclusions : Renying is the Renying(人迎) point from the Stomach Channel(ST), while Cunkou is the Taiyuan(太淵) point from the Lung Channel(LU). These two points are compared in order to determine the deficiency and excess of the Zangfu(臟腑). Normal pulses(平脈) are Soft(軟脈) or Moderate(緩脈), while Stirred pulses(躁脈) are Stringy(弦脈), Tight(緊脈), Slippery(滑脈) or Long(長脈). If the Renying is once active where Shaoyang pulse is active, purge the Gallbladder and supplement the Liver. If there is Stirred pulse, purge the Triple Burner and supplement the Pericardium. If the Renying is twice active where Taiyang pulse is active, purge the Bladder and supplement the Kidney. If there is Stirred pulse, purge the Small Intestine and supplement the Heart. If the Renying is three times active, where Yangming pulse is active, purge the Stomach and supplement the Spleen. If there is Stirred pulse, purge the Large Intestine and supplement the Lung. If the Cunkou is once active where the Jueyin pulse is active, purge the Liver and supplement the Gallbladder. If there is Stirred pulse, purge the Pericardium and supplement the Triple Energizer. If the Cunkou is twice active where the Shaoyin pulse is active, purge the Kidney and supplement the Bladder. If there is stirred pulse, purge the Heart and supplement the Small Intestine. If the Cunkou is three times active where the Taiyin pulse is active, purge the Stomach and supplement the Spleen. If there is Stirred pulse, purge the Lung and supplement the Large Intestine.
