This study was conducted to investigate the effect of weight control by use of commercial formula diet and nutrition education on 36 obese women over a period of 6 months. During the study it motivated ways for women to control their weight and improve their health, thus analyzing variables that influence weight control. To help weight control, for the first 3 weeks, along with 1 regular mea, 2-3 liquid formula diets of 135㎉ per pack a day were provided within the 1,200-800㎉ range. For 6 months since then, all 3 meals were taken regularly and it was recommended that energy which is 500㎉ less than energy requirement be taken. To evaluate the effect of weight change by the weight control program, anthropometric measurements, biochemicl parameter, and food behavior are measured. The mean body mass index(BMI) was 30.1$\pm$3.8(25.0-43.6) and it was in the upper 5 percentile of the mean BMI of Korean women. The percent of body fat was significantly reduced from 29.1$\pm$2.4 to 26.4$\pm$2.3, showing that the weight control program induced not only a change in weight but also a change in body composition. The body circumference such as waist and hip circumference and skinfold thickness measurements of biceps, triceps, subscapular and surprailiac were reduced significantly, but the mean waist-to-hip ratio didn't change. Singnificantly improved food behavior score measured by the questionnaire indicated that the weight-contorl program induced the change of the food behavior, as well. Weight loss also induced biochemical parameters of the subject, thus total cholesterol, LDL-Cholesterol, and triglycerol which were in the high range of the normal values were reduced to 20.2%(p<0.01), 22.2%(p<0.01), 25.8%(p<0.01), repectively. HDL-cholesterol didn't change significantly, but the ratio of HDL to total cholesterol increased(p<0.01).
The somatotropic (GH-IGF-I) axis consists of many hormonal and nutritional factors that control GH release from the somatotrophs in the anterior pituitary. The GH-releasing substances are GHRH and GHS (GHRP or ghrelin), while the GH release-inhibiting substances are somatostatin (SRIF), insulin-like growth factor-I (IGF-I), leptin and glucocorticoids. However, there is evidence showing that nutrition is involved in the control of the somatotropic axis. In addition, weaning is a drastic event for neonates because their alimentary and endocrine circumstances are changed due to the switch, even if gradual, from a liquid milk diet to one composed of such solids as hay and grains. The biological role of ghrelin is one of the hormonal factors that have been focused on ever since ghrelin was discovered at the end of the last century. A 27-amino acid peptide that is mainly synthesized and released from the abomasum epithelium, ghrelin has not been fully evaluated in relation to the somatotropic axis of the ruminant. It has also proven difficult even to investigate the cellular mechanisms of ghrelin action, because this hormone exerts animal-species-dependent actions via a complex set of intracellular signaling pathways. This is also the case for the action of leptin. Another substance, IGF-I, shows a partial inhibitory action on GH secretion in the ruminant. The effect of nutrition is also different among animal species. This is evident by the fact that undernutrition suppresses the circulating GH levels in rodents, but increases it in ruminants and humans. Recently, weaning has been shown to change the postprandial GH responses in ruminants; milk feeding increases, but hay and concentrate feeding suppress, the postprandial circulating GH levels. Even if the postprandial GH level is increased, the ghrelin level is decreased by milk feeding. Macronutrients also possess stimulatory and inhibitory actions on GH secretion in vivo and in vitro. These findings indicate the complexity of the control mechanisms of the somatotropic axis. In the present review, we summarize recent findings on the factors controlling the axis of the ruminant.

A four-week-old female Scottish Fold cat weighting 0.6 kg was admitted for vaccination. During the physical examination, the liquid feces were observed from the vulva and the anus was imperforate. The location of a narrow fistula and distended colon were identified on the contrast radiography. Definitive diagnosis was made as type III atresia ani with rectovaginal fistula. Anal reconstruction and ligation of the fistula were successfully undertaken to treat atresia ani. After surgery, the cat was treated with lactulose and a special diet consisting of high fiber was fed to increase digestibility. The cat was able to control defecation after 2 weeks post-operation. There was no complication for 8 months after surgery.
Effect of dietary essential oils on growth, feed utilization and meat yields of white leg shrimp L. vannamei was investigated. White shrimp fry weighing 0.62 g were kept in one of 12 tanks (75 head/500 L holding tank) in a closed recirculation system. Four experimental diets, a commercial diet (control), phytoncide oil (PO), oregano oil (OO) and fermented garlic liquid (GL) were fed for 16 weeks. The mean water quality values for the whole experimental period were $27.8{\pm}1^{\circ}C$, $7.6{\pm}0.3$, $15.5{\pm}0.3$ g/L and $6.1{\pm}0.3$ mg/L for water temperature, pH, salinity and dissolved oxygen, respectively. At the end of the trial, 10 shrimp per tank were randomly sampled and meat yields (%) were evaluated after peeling the shell and removing the head. After a 16 week feeding trial, final weight of shrimp ranged from 21.9 g to 23.6 g. Feed conversion was not significantly different among groups (p>0.05), which was the lowest (1.95) in the control and highest (2.30) in the PO. Specific growth rate was also not significantly different (p>0.05) and ranged from 3.18% to 3.25%. Average daily gain of 0.2 g was obtained in all treatments. Mortality varied from 35.1% for control to 44.9% for OO. Meat yields maintained constant at 52.1% for control to 53.0% for PO. The study suggested that natural essential oils could not exert any improvement in growth performance, mortality and meat yields of white leg shrimp.
Chronic alcohol consumption is associated with perturbation of hepatic metabolism of sulphur-containing amino acid. The goal of present study was to evaluate the influence of dietary supplementation of methionine or folate to chronically ethanol-fed mts on the metabolism of sulfur-containing amino acids and one-carbon metabolism. Sprague-Dawley male mts were fed Lieber-Decarli liquid diet with 0% ethanol (control), 36% ethanol (E), 36% ethanol combined with methionine supplement (EM) or folate supplement (EF) for 8 weeks. Hepatic S-adenosylmethionine (SAM) and S-adenosylhomocysteine (SAH), plasma folate and homocysteine (Hcy), urinary excretion of folate and formiminoglutamate were investigated after feeding experimental diets. Growth was retarded by 36% ethanol consupmtion (E, EM and EF) (p<0.01). Liver total fat (p<0.05) and plasma ALT (P<0.01) were increased by methionine supplementation (EM), implicating fatty liver and liver injury. Liver folate was increased slightly by folate supplementation (EF) (p=0.077). Urinary folate loss was increased 2.3 fold by ethanol consumption (E) and 17.2 fold by folate supplementation (EF), while decreased by methionine supplementation (EM) (p<0.000l). Plasma Hcy was increased 1.9 fold by methionine supplementation (EM) in ethanol-fed mts (p<0.05), which was related with decreased methionine synthase activity (p<0.05). Hepatic SAM/SAH ratio was depressed by methionine supplementation in ethanol-fed mts (EM) (p<0.05). Urinary formininoglutamate (Figlu) excretion after histidine loading was increased by ethanol ingestion and reduced by methionine supplementation (p<0.00l). Based on these data, methionine supplementation appears to accelerate histidine oxidation. In conclusion, dietary supplementation of methionine to ethanol-fed mts exacerbates alcoholic liver injury possibly by complicating sulphur-containing amino acid metabolism, as while it may have beneficial effects on folate and histidine metabolism.

The fatty acid composition of human milk was determined in 20 milk samples (ten colostrum and 10 mature) obtained at different stages of lactation. Human colostrum contained a lower percentage of total lipids than mature milk. In comparison with mature milk, human colostrum was characterized by a lower percentage of saturated fatty acids, a higher percentage of monounsaturated fatty acids and a higher percentage of extra-long-chain polyunsaturated fatty acid metabolites of both linoleic acid ($\omega$ 6 series) and linolenic acid ($\omega$ 3 series). The linoleic acid levels reported here are considerably higher than those reported previously in Korea. This shift has paralleled an increase in the use of vegetable oils in Korean diet. The human mature milk differed from marketing cow's milk in fatty acid composition, as it had a lower content of short-, medium-and long-chain saturated fatty acids and a higher content of long-chain monounsaturated and polyunsaturated fatty acids.

Enrofloxacin (ENRO) is one of the most commonly used fluoroquinolones for treating bacterial disease in olive flounder (Paralichthys olivaceus) farming, but its withdrawal time for industrial-scale farming has not been well established. Withdrawal times of ENRO following oral administration were evaluated in olive flounder under field conditions. Fish were held in an inland fish tank and fed a commercial mediated diet containing 5 mg/kg of ENRO for 9 days. Seven fish per sampling point were examined during and after treatment. ENRO and its major metabolite, ciprofloxacin (CIP), were analyzed using high-performance liquid chromatography with a fluorescence detector. The concentration of ENRO and CIP in muscle increased during the medication period, and then decreased rapidly The sum of ENRO and CIP concentration in olive flounder peaked on day 6, with a maximal concentration in muscle of 4.30 mg/kg. ENRO residues were eliminated rapidly; at 10 days post treatment, the level in muscle was 0.10 mg/kg, but it took about 50 days to be reduced to below 0.1 mg/kg. After 60 days, the residual concentration was below 0.1 mg/kg in all samples. The level of ENRO accumulation at the beginning of oral administration was variable, according to the farming conditions, but the overall exhaustion time was almost the same. We concluded that an adequate withdrawal period of enrofloxacin is 60 days in the case of oral administration.

Flavonoids including quercetin and rutin are a group of naturally occurring compounds widely distributed in plants, especially in buckwheat. Thus, cereal and the leaf of the plant have increasingly used as a source of nutritional and functional foods such as noodle, cake or soup in Korea, Japan and other countries. This study investigated comparative effects of dietary rutin rich in buckwheat and its aglycone, quercetin, on serum biomarkers and antioxidant parameters in rats treated with chronic ethanol. Rats were fed with the liquid diets prepared by the method of Lieber Decarli. Serum alanine transaminase (ALT) and aspartate transaminase (AST) activities increased significantly by alcohol feeding. Dietary flavonoids including rutin, quercetin and their mixtures (1/1, v/v) decreased significantly the activities of serum ALT whereas the feeding of quercetin decreased only the activity of serum AST. The concentration of serum malondialdehydes elevated by chronic alcohol feeding decreased markedly in all the experimental groups that were fed with the flavonoids; however, the combined administration of quercetin or rutin, but not that of rutin or quercetin alone decreased significantly the concentration of liver malondialdehydes to the normal range in rats fed without ethanol. Our results suggested that dietary combined mixture of rutin and quercetin might be effective in ameliorating adverse responses seen in rats exposed to ethanol chronically.

Hepatic disease has been noted and reported for involvement various detrimental factors. Among many detrimental injury factors, alcohol has been noted for hepatitis, fatty liver, fibrosis, and hepatic cirrhosis. The purpose of this study is to develop animal model for hepatic fibrosis in pig with ethanol, and to search new anti-fibrogenic agent. Twelve male Landrace pigs were divided into 3 groups of 4 animals each. Group 1, 2 and 3 were fed with ceramic water only, ceramic water + liquid diet containing 20% ethanol and normal tap water + containing 20% ethanol for 12 weeks, respectively. At week 12, all pigs were immediately sacrificed for collection each tissue and blood. Serologically, serum ALT and AST levels were significantly reversed in group 2, comparing to group 3. They were normal range in pigs of group 1. Microscopically, macrovesicular lipid droplets and moderate necrosis were evident in the tap water + ethanol fed group 3. However, ceramic water intake group 1 showed normal. Moreover, in group 3, little fatty changes and mild necrosis were observed. Collagen fibers were detected in the spaces of surrounding periportal and interlobular areas in the group 3 of tap water + ethanol, but collagen synthesis and its thickness of fibrotic septa connecting portal tracts was markedly reduced in the group 2 of ceramic water + ethanol. In immunohistochemistry, myofibroblasts were detected in the ethanol and tap water treated group 3. No or a few myofibroblasts were observed in groups 1 and 2. CYP 2E1 was rarely detected in group 1 fed ceramic water. However, group 2 showed slightly activation of CYP 2E1 in the area of pericentral, while CYP 2E1 was significantly activated in group 3 fed tap and ethanol. Taken together above, alcohol fibrosis model in pig was established. Furthermore, ceramic water had an inhibitory and protecting ability for alcohol-induced hepatic damages.

Objectives : This study investigated the liver-protective effects of MJY2018, a Herbal formula, against alcoholic fatty liver disease and anti-oxidative effects. Methods : Its effects were investigated in an alcoholic fatty liver disease model in male C57BL/6 mice, which were fed Lieber-DeCarli liquid diet containing ethanol. MJY2018 (100 and 200 mg/kg bw/day) or silymarin (50 mg/kg bw/day) were orally administered daily in the alcoholic fatty liver disease mice for 16 days. Results : The results indicate that MJY2018 promotes hepatoprotection by significantly reducing aspartate transaminase (AST) and alanine transaminase (ALT) levels as indicators of liver damage in the serum. Furthermore, MJY2018 reduced accumulation of triglyceride and total cholesterol, increased levels of superoxide dismutase (SOD) and glutathione (GSH) in the livers of the alcoholic fatty liver disease mice model. Additionally, it improved the serum alcohol dehydrogenase (ADH) activity. Conclusions : These results indicate that MJY2018 were effective in improving and protecting oxidative stress and alcoholic liver disease.
