Waterpepper is a weed which grows on damp soil. especially near swamps, and in shallow water of ponds and ditches. It Is widespread throughout the country In abundant colonies. In the present experiments, possible toxic effects of waterpepper were investigated in ruminants. Pour cows were fed waterpepper ad libitum or by force in the from of green forage, hay and/or powder, 8 goats were administered in the form of methanol extract, and 4 goats, crude juice, into the lumen. Clinical signs were examined as well as urinalysis, hematology, serum chemical analysis, pH/blood gas analysis and chclinesterase activities following administration of waterpepper. Six goats which were administered the methanol extract or crude juice were sacrificed for pathological examinations., In addition to the clini copathological examinations, the chemical constituents of waterpepper were qualitively analyzed from the methanol extract and the Effects of the waterpepper crude juice were examined on the motility of rabbit duodenum and uterus. It is revealed that waterpepper contains steroids, terpenoids, flavonoids, tannin and essential oils in the methanol extract and nitrates in the crude juice. The crude juice of waterpepper relaxed the rabbit uterine and duodenal smooth muscles. The constraction of duodenum by acetylcholine or BaCl$_2$ were partially inhibited by pretreatment of the crude juice. However, the relaxation of duodenum by the crude juice was not blocked by the pretreatments of phenoxybenzamlne, propranolol, cocaine, reserpine and tetrodotoxin. The constituents of waterpepper to evoke elaxation of duodenal smooth muscle were stable to heat. The cows administered waterpepper showed common clinical symptoms such as acrid expression, restlessness, dullness, inappetence, anorexia, severe diarrhea, mild bloat and left displacement of abomasum, while bloody feces was shown in a cow. The goats administered the mothanol extract showed common clinical signs such as acrid expression, restlessness, dullness, inappetence and soft feces, while bloody feces was shown in a goat, A goat adminstered the crude juice showde bloody feces and diarrhea. Respiratory rates and heart beats were increased along with diarrhea in the experimental cows. The erythrocyte counts and MCHC were decreased whereas PCV, MCV and neutrophils were increased in the cows administered waterpepper. In goats administered methanol extract, there were decreases in erythrocytes, PCV and hemoglobin content, and an increase in MCHC. The goats ingester with the crude juice showed negligible changes in hematologic values compared with control group which was administered the same amount of water instead of the crude juice. The contents of serum calcium, Inorganic phosphorus, magnesium, Iron, glucose, cholesterol, total protein, triglycerides and phospholipids were tended to decrease in cows. In goats serum iron, glucose, triglycerides, cholesterol, BUN and phospholipids content were decreased while the content of sodium and chloride were increased after administration of the methamol extract The goats ingested with the crude juice did not show significant changes in serum chemical analysis. Even though there were some pathological findings such as hyperemia in the small intestines and kidneys and swelling of liver parenchymal cells, the values of serum AST, ALT, LDH, alkaline phosphatase, total bilirubin and creatinine did not change significantly. While proteins, hemoglobin and blood were detected in the urine of cows, urine pH, ketone bodies, glucose, bilirubin and urobilinogen content were normal or undetected. There were no significant changes in pH/bolld gas analysis data of cows and cholinesterase activities of plasma and erythrocytes of cows and goats ingested with waterpepper or the methanol extract. It is concluded that waterpepper irritates the gatrointestinal system, causes abdominal pain, relaxes the gastrointestinal smooth muscle and dilatates blood vessels supplied to the system. The irritation and relaxation may lead to abnormal fermentation, maldigestion and malabsorption of nutrients and result in diarrhea, body feces, mild bloat and left displacement of abomasum.

본 연구에서는 인체 폐암 세포인 A549를 사용하여 택란 메탄올 추출물의 항암활성과 그 분자적 기전에 관하여 연구하였다. 먼저 택란 추출물이 A549의 세포증식에 미치는 영향을 알아본 결과 처리 농도 및 시간 의존적으로 A549의 성장이 저해되었으며, 세포 주기 변화를 분석한 결과 강력한 G1 arrest가 유도되는 것을 확인하였다. 이러한 택란 추출물에 의한 G1 arrest는 세포주기 조절 단백질인 Cyclin D1, Cyclin E 및 Cyclin-dependent kinase인 CDK2, CDK4, CDK6의 발현 감소와 연관되어 있었다. 또한 택란 추출물에 의한 CDK/Cyclin complex의 발현 저해는 DNA 손상에 의해 활성화되는 CHK2의 활성화 형태인 p-CHK2의 발현 증가에 따른 CDK 활성화 효소인 Cdc25A phosphatase의 발현 억제에 의해 나타나는 결과로 사료된다. 반면 종양억제유전자인 p53 및 CDK 억제제인 p21과 p27의 발현량은 증가되지 않았다. 이러한 결과들로부터 택란 추출물은 DNA damage에 의한 ATM/CHK2/Cdc25A/CDK2 pathway를 통해 A549의 G1 arrest를 유도하여 세포의 증식을 억제할 것으로 판단되며, 이때 택란 추출물에 의해 유도되는 G1 arrest는 p53 비의존적인 경로일 것으로 사료된다. 본 연구결과는 택란이 Cdc25A를 target으로 하는 새로운 항암활성 소재로서 사용될 수 있는 가능성을 시사한다. 또한 본 연구결과는 택란 추출물의 세포주기 조절에 의한 항암기전을 이해하고 향후 지속적 연구를 하는 데 있어서 귀중한 기초자료로 사용될 수 있을 것이다.

This study was conducted to investigate the effects of dietary Allium hookeri on growth performance, bone strength, and blood biochemical profiles in growing broiler chickens. Twelve hundreds of one-day old Arbor Acres male broilers were divided into 6 treatments with 4 replicates and 50 birds per replicate (n=200 chicks/treatment). Chickens fed basal diet (Control), basal diet with commercial X (Positive control) at 0.05% of diet, or each one of the experimental diets (L3, L5, R3, R5) supplemented with the powder of A. hookeri leaf or root at 0.3 and 0.5% of diet respectively for 5 weeks. At the 5th week of feeding the diets, body weight, tibia strength, and blood biochemical profiles including antibody titers were measured. Dietary A. hookeri (L3, L5, R3, R5) significantly increased final body weight than the control group. And the dietary leaf of A. hookeri effectively increased the growth performance than dietary root of A. hookeri. Interestingly dietary leaf of A. hookeri improved tibia strength than the control group and L3 showed the highest value. The antibody titers against infectious bursal disease (IBD) increased with the addition of dietary leaf of A. hookeri compared with positive control, R3, and R5 groups. But there was no significant difference in serum biochemical parameters such as albumin, globulin, glucose, cholesterol, Ca, P, total protein, total bilirubin, alanine aminotransferase, alkaline phosphatase, and gamma-glutamyl transferase. These results suggest that A. hookeri can be used as a good supplement to improve growth performance and health by increasing bone strength and antibody titer against IBD without any anti-nutritional or toxic effects in growing broilers.

This study was conducted to identify the effects of caffeine on the lipid and protein components or blood chemistry levels of the serum as well as the total homogenate, mitochondrial and microsomal fraction of the rat(Sprague-Dawley, female) liver. Acute test were conducted to determine those effects. The acute test was conducted by dividing rats into 7 groups according to the time lapsed after a single oral administration of 100mg/kg caffeine(that is control, 2hrs, 4hrs, 8hrs, 24hrs, 48hrs and 72hrs lapsed group). The concentrations of glucose, urea nitrogen, uric acid, creatinine, total protein, albumin, A/G ratio, triglyceride, total cholesterol, HDL-cholesterol, free fatty acid, phospholipid as well as the activities of alanine aminotransferase(ALT), aspartate aminotransferase(AST) and alkaline phosphatase(ALP) were measured in the serum of each experimental groups. The concentrations of the carbonyl group, malondialdehyde(MDA) and the patterns of the SDS-PAGE(Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis) were analyzed to determine the oxidative damages and metabolic changes on the lipid and protein components in the serum, and total homogenate, mitochondrial and microsomal fractions of the rat liver. The results obtained from this study were summarized as follows; 1. The concentrations of serum glucose were significantly higher(p<0.01) between 4(143.0mg/dl) and 8hrs(138.0mg/dl) in comparison to that of the control(101.1mg/dl) after a single oral administration of caffeine(100mg/kg). While on the other, there were no significant differences in the concentrations of urea nitrogen, uric acid, creatinine, total protein, albumin and albumin/globulin(A/G) ratio in comparison to those of the control. 2. The concentrations of total cholesterol and HDL-cholesterol in serum were significantly higher(p<0.01) between 4(77.4mg/dl, total cholesterol) and 8hrs(64.7mg/dl, HDL-cholesterol) in comparison to those of the control(62.8, 46.7mg/dl) after a single oral administration of caffeine(100mg/kg). On the other hand, the concentrations of triglyceride in serum were significantly lower(p<0.01) after 8hrs(38.8mg/dl) in comparison to that of the control(66.5mg/dl). 3. The activities of AST in serum was significantly higher(p<0.05) from 2hrs(149U/L) to 8hrs(178U/L) in comparison to the control(112U/L) after a single oral administration of caffeine(100mg/kg). The activities of ALT in serum were significantly higher(p<0.01) at 4(45.5U/L), 24(49.3U/L), 48(46.8U/L) and 72 hrs(42.3U/L) in comparison to that of the control(39.7U/L) after a single oral administration of caffeine(100mg/kg). On the other hand, there were no significant differences in the activities of ALP in comparison to that of the control. 4. The concentrations of free fatty acid in serum were significantly higher(p<0.01) at 8hrs(65.0mg/dl) in comparison to that of the control(37.6mg/dl) after a single oral administration of caffeine(100mg/kg). However, there were no significant differences in the concentrations of carbonyl group and malondialdehyde within serum, and liver homogenate, mitochondrial and microsomal fractions in comparison to that of the control. 5.

The chronic test was conducted by dividing rats into 5 groups according to the type of drugs and dosages administrated as follows; the control(group A), and group B was given 25mg/kg caffeine orally once daily for 30 days, group C was given 50mg/kg caffeine orally once daily for 30 days, group D was given 25mg/kg caffeine and orally ferric chloride once daily for 30 days and group E was given 25mg/kg caffeine and 25mg/kg vitamin E once daily for 30 days. The concentrations of glucose, urea nitrogen, uric acid, creatinine, total protein, albumin, A/G ratio, triglyceride, total cholesterol, HDL-cholesterol, free fatty acid, phospholipid as well as the activities of alanine aminotransferase(ALT), aspartate aminotransferase(AST) and alkaline phosphatase(ALP) were measured in the serum of each experimental groups. The concentrations of the carbonyl group and malondiaidehyde(MDA) and the patterns of the SDS-PAGE(Sodium Dodecyl Sulfate - Polyacrylamide Gel Electrophoresis) and fatty acid compositions in free fatty acids and phospholipids were analyzed to determine the oxidative damages and metabolic changes on the lipid and protein components in the serum, and total homogenate, mitochondrial and microsomal fractions of the rat liver.
