Hexane, chloroform, methanol and water extracts of Paeoniae Radix were tested on the experimentally induced hypercholesterolemia in rats for lowering effect of serum lipoprotein contents. Hyperlipidemia was induced on male Wistar rats by feeding high cholestetrol diet for 7 days. Serum lipid profile was verified on these rats by measuring total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL), and low density lipoprotein cholesterol (LDL). Then, the diet was changed to normal. At the same time, hexane, chloroform, methanol and water extract of Paeoniae Radix were given orally on daily basis, and the changes in the serum lipid profile were assessed for 4 weeks. Methanol extract of Paeoniae radix decreased TC level at 1, 2, and 4 week point significantly, and water extract decreased TC level at 4 week point significantly comparing with the control group.

Urethral obstruction is a life-threatening feline lower urinary tract disease (FLUTD). The rate of recurring urethral obstruction was 14.8-58.1% after the first occurrence. Ultrasonographic findings associated with reobstruction had been rarely reported although ultrasonography was a valuable technique for diagnosing urinary bladder calculi and distinguishing different FLUTD causes. This retrospective study aims to describe the ultrasonographic findings, urinalysis, and serum chemistry profile in cats with FLUTD and determine the associations of reobstruction with ultrasonographic findings, urinalysis, and serum chemistry profile. The present study included 141 cats that were followed up for more than 1 year. The ultrasonographic criteria included the presence of cystolithiasis, urine echogenicity, sediment, suspended linear strand, pericystic effusion, hyperechoic pericystic fat, ureteral dilation, pyelectasia, and perirenal effusion. The urinalysis criteria included hematuria, urine-specific gravity, pH, sediment, and proteinuria. The most common ultrasonographic findings in cats with FLUTD were echogenic urine and sediment. However, this study did not find an association between reobstruction and ultrasonographic findings, urinalysis, and serum chemistry profiles. Thus, an ultrasonographic examination may be insufficient to predict the risk of reobstruction although it is a useful modality for diagnosing FLUTD and making treatment direction.

The overall purpose of this study was to investigate the effects of Chunggukjang and Greentea-Chunggukjang on the lipid profile, lipid peroxidation and antioxidative enzyme activities of liver tissue in growing male rats fed cholesterol. Twenty seven rats were divided into three treatment groups (Control, Chunggukjang and Greentea-Chunggukjang) and were given experimental diets with 1% cholesterol for 9 weeks. All rats in this study were fed a casein-based diet. Chunggukjang groups were fed diet containing 33.1% Chunggukjang powder. The Chunggukjang and Greentea-Chunggukjang groups showed significantly lower weight gain, food efficiency ratio than the control group regardless of Chunggukjang type. Serum total cholesterol was significantly lower in the Chunggukjang group than in the control group, whereas serum triglyceride and atherogenic index were significantly lower in the Greentea-Chunggukjang group than in the control group. Hepatic triglyceride contents was not significantly different among the diets. However, hepatic cholesterol content was significantly lower in the Greentea-Chunggukjang group than in the control group. Lipid peroxidation of malondialdehyde (MDA) contents was significantly lower in the Chunggukjang and Greentea-Chunggukjang groups than in the control group. Activity of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and catalase (CAT) in liver tissue of the Chunggukjang and Greentea-Chunggukjang groups were not significantly different. It can be concluded that Chunggukjang and Greentea-Chunggukjang influence lipid profile and hepatic malondialdehyde contents in growing male rats fed cholesterol.

In middle-aged men, abdominal obesity has been an important risk factor of coronary artery disease (CAD) as well as a predictor of hypertension, dyslipidemia, insulin resistance and glucose intolerance. Particularly, risks from abdominal obesity increase when adipose tissue accumulates in visceral compartment. Many studies showed that weight reduction by caloric restriction improves abdominal obesity and reduces lots of cardiovascular risk factors. Testosterone treatment also results in a significant decrease in visceral fat area and normalizes endocrine metabolism. However there is no study that compare the effect of caloric restriction with that of testosterone treatment. The purpose of this study is to investigate the effect of caloric restriction and that of testosterone treatment on body fat distribution, serum lipids and glucose metabolism in male patients with CAD. Forty five middle-aged overweight-obese men with CAD participated in 12 weeks' program. They were matched with age, body weight, body mass index (BMI) and divided into three groups : control group (n = 15) , caloric restriction group (-300 kcal/day, n = 15) and testosterone treatment group (testosterone undecanoate tablets, n = 15) . After 12 weeks, control group did not have any changes in anthropometries, lipid profile, body fat distribution, glucose metabolism and hormonal status. Expectedly, caloric restriction group showed decreases in body weight, BMI, waist to hip ratio, ％ body fat. Ten percentage of total cholesterol and 23% of triglyceride in serum were also decreased. In body fat distribution, total fat areas at both L1 and L4 levels were significantly reduced in this group without reduction in muscle of thigh and calf. However, testosterone treatment group did not have any significant changes in body weight, ％ body fat, serum lipid profile and abdominal fat distribution. In conclusion, weight reduction by caloric restriction is more beneficial in body fat distribution and serum lipid level than testosterone treatment in overweight male patients with CAD. This result suggests that modest weight reduction is possible to help decrease risk factors of CAD.

This experiment was conducted to investigate the effects of three different copper (Cu) sources (one inorganic and two organics) and levels (0, 50, and 100 mg/kg) on the growth performance, Cu digestibility, fecal mineral excretion, serum mineral concentration, jejunal morphology, and serum biochemical profile of growing pigs. A total of 42 male, growing pigs (31.08 ± 1.82 kg) were randomly assigned to seven treatments consisting of one negative control (0 mg/kg of added Cu level) and treatments with copper sulfate (CuSO4), Cu-amino acid complex (CuAA), and Cu-hydroxy-4-methylthio butanoate chelate complex (CuHMB) at 50 and 100 mg/kg each for 28 d. Pigs fed 50 or 100 mg/kg of Cu showed improved (p < 0.05) average daily gain and feed intake. Although Cu excretion decreased (p < 0.01) in pigs fed 100 mg/kg of organic Cu sources compared to those fed CuSO4, there was no difference between the Cu sources in pigs fed 50 mg/kg. However, the apparent total tract digestibility of Cu increased (p < 0.01) in pigs fed organic Cu sources compared with that in pigs fed CuSO4. The addition of CuHMB increased (p < 0.01) serum phosphorus and sulfur concentrations; however, there were no effects of source and level on jejunal morphology and serum biochemical profile. These results suggest that the inclusion (50 mg/kg) of organic Cu sources (CuAA and CuHMB) in the growing pig diet could be beneficial for growth performance and Cu availability and may reduce environmental pollution.

An experiment was conducted to establish a large scale production method of anti-serum against chicken IgA and to profile the developmental changes of serum IgA levels during the feeding period(from hatching to 7 weeks of age) in broiler chicks. Blood samples were taken from Hubbard chicken at the age of hatching, 3 days of age, and weekly thereafter till to 7 weeks of age. The pure IgA was isolated from ammonium sulfate treated chicken bile juice by gel filtration chromatography ( Sepharose GL-6B) - The quantitative assay of serum IgA were carried by RID method. Developmental changes of serum IgA concentrations were 0.42 mg /mL at hatching, thereafter dicreased gradually, lowest at 1 week of age(0.17 mg /mL), and gradually increased to 7 weeks of age(2.73 mg /mL). There was no sexual difference in serum IgA level, but female chicks showed higher IgA levels than male chicks during the experimental period.

Dietary and other factors affecting serum lipid levels of 103 rural women aged 30-76 years were assessed. Data for dietary intakes were obtained by 24-hour recall method. Body weight, height and blood pressure were measured and BMI was calculated from the anthropometric data. Serum samples were collected and analyzed for TG and lipoprotein fractions. Relation of the factors with serum lipid concentration was analyzed by Pearson's correlation coefficient(r). The results were summarized as follows: The weight, hight and BMI of the subjects were 56.8kg, 152.4cm and 24.5k/==, respectively. 31.8% of the subjects under 50 years of age($\leq$49yr group) and 61.0% of the subjects from 50 years up(==50yr group) were classified as hyperlipidemia. Most of the subjects had normal blood pressure but 8.5% were hypertensive. Total food intake of hyperlipidemic subjects was more than those of normal subjects in both age groups. Nutrients intake also tended to be higher in hyperlipidemic subjects of $\geq$50yr group. Intake of some foods like nuts, milk, or meat affected serum lipid profile even though the effects was somewhat different between two age groups. Body weight was positively related with serum TG and VLDL-cholesterol in $\leq$49yr group, and body weight as well as height and BMI affected serum lipid level in $\geq$50yr group. In summarization, it appeared that hyperlipidemia was a serious health problem in rural women. Hypertriglyceridemia due to sharp increase after 50 years old was remarkable and further research should be performed to determine the related factors in the near future.

The objective of the current study was to evaluate the effect of supplementation of either L-methionine (L-Met) or DL-methionine (DL-Met) to diets of starter pigs on nitrogen (N) balance, metabolism, and serum amino acid profile. Eighteen crossbred ($Duroc{\times}Landrace{\times}Yorkshire$) barrows weighing $15.45{\pm}0.88kg$ were randomly allotted to 1 of 3 diets with 6 pigs per treatment. The diets included a basal diet (Met-deficient diet) containing 0.24% standardized ileal digestibility Met with all other essential nutrients meeting the pig's requirements. The other two diets were produced by supplementing the basal diet with 0.12% DL-Met or L-Met. The experiment lasted for 18 days, consisting of a 13-day adaptation period to the diets followed by a 5-day experimental period. Pigs were fed ad libitum and free access to water throughout the experiment. Results showed that the supplementation of either L-Met or DL-Met improved N retention, and serum methionine concentration, and decreased N excretion compared with basal diet (p<0.01). The N retention of pigs fed diets supplemented with the same inclusion levels of DL-Met or L-Met were not different (p>0.05). In conclusion, on equimolar basis DL-Met and L-Met are equally bioavailable as Met sources for starter pigs.
