  • The objective of this study was to examine the effect of supplementation of high linoleic ($C_{18:2}$) oil or high linolenic ($C_{18:3}$) oil to the diet on milking performance and content of conjugated linoleic acid (CLA) isomers in goat milk fat. Forty five dairy goats (Sumnen, 25 d post-partum, $62.5{\pm}1.2kg$) were randomly assigned to three treatment groups with each group of 15 dairy goats. The goats were fed a basal diet (CON) consisting 1.2 kg concentrate and 1.2 kg chopped hay (0.6 chopped alfalfa and 0.6 kg hay) daily with 4% soybean oil (SO) or 4% linseed oil (LO). Daily feed intake was not influenced (p>0.05) but daily milk yield (p<0.001) and milk fat yield (p<0.001) were significantly increased by supplementation of oils. Supplementation of oils decreased the short chain fatty acid, medium-chain fatty acid and saturated fatty acid in goat milk fat while increased trans vaccenic acid (trans-11-$C_{18:1}$, TVA), oleic acid ($C_{18:1}$), $C_{18:2}$, $C_{18:3}$, cis-9, trans-11-CLA (c9, t11-CLA), trans-10, cis- 12-conjugated linoleic acid (t10, c12-CLA), unsaturated fatty acids, mono unsaturated fatty acid and long-chain fatty acid in goat milk fat (p<0.001). Especially, c9, t11-CLA, t10, c12-CLA and ${\omega}-3$ fatty acid ($C_{18:3\;n-3}$) in milk fat were highest when goat fed LO diet. Based on the result, it is suggested that supplementation of linseed oil should be an effective method to increase CLA isomers and ${\omega}-3$ fatty acid in goat milk fat without negative effect on lactating performance.

  • The objective of this study was to investigate the influence of three types of protein source in a basal diet during the prenatal and lactating periods on the cellular growth and development of organs in rate. Twenty four pregnant Sprague-Dawley rats weighing 187.7${\pm}$18.5 g were fed ad libitum diets containing casein, soy protein, or corn gluten. The weight of organ and the contents of DAN, RNA, and protein of organs in pups were determined at 0, 3, 7, 14, and 21 days after the birth. Dietary intake of rats during trimester of pregnancy and lactation were significantly higher in the rats fed case in containing diet than those of rats fed the corn gluten diet. Body weight of the progeny fed casein diet at birth and after 7 days were significantly higher than those of rats fed the corn gluten diet. The weight of brain, liver, and kidney of pups which fed corn gluten diet were significantly lower than those fed the casein diet. DNA contents in the brain of pups fed the casein and the soy protein were slightly higher than those fed the corn gluten diet. RNA and protein contents of the brain, and DNA, RNA and protein contents of the liver of the corn gluten treated group were significantly lower than those of the others.

  • Effect of the egg yolks from laying hens intubated, p.o., astaxanthin (designated AEY) on the catabolic response overcome of mice was examined. Female ICR mice (6~7 weeks of age) were adapted in a temperature- and humidity-controlled house for one week and randomly divided into 5 groups (6 mice/cage/treatment). Mice were intubated p.o., AEY (5, 10 and 15 mg), control egg yolk (CEY, 10 mg), or fish oil (5 mg) dissolved in 0.2 mL phosphate buffered saline (PBS) every two days for 14 days. At day 15, the 0.1 mL of lipopolysaccharide solution (LPS, 30$\mu\textrm{g}$/0.1 mL 10 mM HEPES) was injected through tail vein, and then, the body weight of mouse and the amount of feed intake were measured over a period of 72 hours. Control group mice were received only PBS and LPS. AEY treatment suppressed the loss of mice body weight in a dose-response manner. Twenty four hours post LPS injection, the reduced body weight per mouse of AEY 5, AEY 10, and AEY 15 mg treatment groups was 3.70, 3.54, and 3.25 g, respectively. Body weight suppression effect of AEY treatment was greater than that of CEY, but less than fish oil. AEY treatment did not alter thymus weight, but increased the weight of spleen or liver. These results indicate that AEY suppressed the loss of body weight by LPS via any function of the spleen and/or liver.

  • Health concern of dogs is the most important issue for pet owners. People who have companied the dogs long-term provide the utmost cares for their well-being and healthy life. Recently, it was revealed that the population and types of gut microbiota affect the metabolism and immunity of the host. However, there is little information on the gut microbiome of dogs. Hericium erinaceus (H. erinaceus; HE) is one of the well-known medicinal mushrooms and has multiple bioactive components including polyphenol, β-glucan, polysaccharides, ergothioneine, hericerin, erinacines, etc. Here we tested a pet food that contained H. erinaceus for improvement in the gut microbiota environment of aged dogs. A total of 18 dogs, each 11 years old, were utilized. For sixteen weeks, the dogs were fed with 0.4 g of H. erinaceus (HE-L), or 0.8 g (HE-H), or without H. erinaceus (CON) per body weight (kg) with daily diets (n = 6 per group). Taxonomic analysis was performed using metagenomics to investigate the difference in the gut microbiome. Resulting from principal coordinates analysis (PCoA) to confirm the distance difference between the groups, there was a significant difference between HE-H and CON due to weighted Unique fraction metric (Unifrac) distance (p = 0.047), but HE-L did not have a statistical difference compared to that of CON. Additionally, the result of Linear discriminate analysis of effect size (LEfSe) showed that phylum Bacteroidetes in HE-H and its order Bacteroidales increased, compared to that of CON, Additionally, phylum Firmicutes in HE-H, and its genera (Streptococcus, Tyzzerella) were reduced. Furthermore, at the family level, Campylobacteraceae and its genus Campylobacter in HE-H was decreased compared to that of CON. Summarily, our data demonstrated that the intake of H. erinaceus can regulate the gut microbial community in aged dogs, and an adequate supply of HE on pet diets would possibly improve immunity and anti-obesity on gut-microbiota in dogs.

  • The newborn human is the only mammalian whose mother does not have a food supply ready for it's offspring at birth. From two to four days usually elapse before the mother's supply If milk appears, and during this period, some kind of artificial feeding should be supplied to the infants. Because of this factor, there has been continued debate fog the past hundreds of years as to when the first feeding should be started Accordingly, many experiments were carried out by scholars and because of these, Pre-lateral feedings were believed to be necessary. Many types of pre-lateral feedings were tried and the conclusion was reached that glucose water was the best food for the first infants'feedings. Traditionally, This has been started 12 hours after birth. The causes for the 12 hours delay were thought to (1) provide rest for the infants: (2) prevent regurgitation ana vomiting which tended to be prevalent during this tine: (3) in cases of low weight infants, prevention of aspiration pneumonia. From recent studies of newborn physiology and as pediatric medicine has been rapidly advancing, many studies hare been carried out concerning the improvement of infant nutrition and the early feeding of infants has been emphasized. This author believes it would be very beneficial to try two different kinds of feedings for the infant. (1) experimental feedings ana (2) comparative feeding, and during this period to investigate and compare the infants blood sugar level, hematocrit, gamma globulin level weight changes and to observe the infant reaction ill order to search for a more desirable feeding program. This study was conducted from January to March 1974 with data related to 40 healthy newborn infants (male 21, female 19: weight, 2.79∼4.20㎏ : gestation, 39∼40 weeks) born at Ewha Womens University Hospital and the results obtained were as follows : 1. At time of birth the blood sugar level from the cord sample averaged 88.99㎎/100㎖, but the blood sugar level rapidly dropped after 2 to 3 hours and reached the lowest point after 10 to 11 hours (54.48㎎/100㎖) and rose again by the 24 hour time period (76.80㎎/100㎖). Changes in the blood sugar level of the experiments: groups and the compare-five group was not significantly different until the 6 to 7 hour period, but by the 10 to 11 hour period the blood sugar levels of the experimental group (49,10㎎/100㎖) and the comparative group (49.70㎎/100㎖) were lower than the remainder of the experimental groups. 9. There ware no significant weight changes between the two groups. Average weight at birth was 3.35㎏, but at the 24 hours period birth weight averaged 3.29㎏. (1.8% reduction of birth weight). It continually lowered until at 48 hours, average weight was 3.26㎏ (2.7% reduction from birth weight.) 3. Hematocrit readings showed no significant difference between the groups. Hematocrit, the average value at birth, was 28.07% and abruptly elevated to average 64.35% at the 2 to 3 hour period, then slowly lowered to an average of 59.67% at the 6 to 7 hour period, 55.10% at the 10 to 11 hour period, ana 53.70% at the 24 hour period. 4. At birth, average gamma globulin value averaged 1,39㎎/100㎖. and at the 24 hour period averaged 1,52㎎/100㎖ revealing no significant difference between the two feeding groups. 5. Such factors as voiding, passing of meconium, regurgitation and vomiting showed no significance between the two feeding groups. However, the number of infants voiding and passing meconium in the experimental groups during the first 12 hours was slightly greater. In general there was an increased tendency for regurgitation and. vomiting among a small group of the infants during the first 24 hours which thereafter decreased. 6. Fluid intake averaged 24.38cc at the first feeding and increased to average 30.48cc at the third feeding and further increased to 73. 00cc at the fifteenth feeding. Finally it was suggested that the most reasonable method of early feeding is to give less than 25cc of 5% glucose water and/or 8% powdered milk at 8 to 9 flours after birth in order to prevent hypoglycemia and dehydration.

  • We evaluated the anti-diabetic effects of Triticum aestivum sprout water extract (TA) in diabetes mellitus type 2. For the experiments, the diabetic animal model db/db mice were divided to 3 groups: diabetic control (db/db) and two experimental groups orally treated with 25 and 100 mg/kg single dose of TA (TA-25 and TA-100, respectively). The lean mice were used as the non-diabetic normal control. All mice have free access to water and AIN-93 diet. TA was administrated to diabetic mice for 5 weeks and the diabetic clinical markers, including blood glucose level, body weight, food intake and insulin level, were measured at a time. After administration for 5 weeks, the blood glucose level was decreased 1.10 and 1.98 folds in TA-25 and TA-100 groups, respectively, compared with db/db group. The body weight and diet consumption were significantly reduced by TA treatment in dose-dependent manner. The treatments of TA-100 also significantly decreased remarkedly liver weight and slightly serum insulin levels when compared with them of the diabetic control group. However the immunohistochemical staining for insulin clearly showed high expression of insulin in the pancreatic islet cells derived from all db/db mice, even if TA was administrated. Moreover, TA-100 treatment significantly improved impaired glucose tolerance in diabetic db/db mice. The results suggest that TA has anti-hyperglycemic effect attenuating blood glucose in the animal model of type 2 diabetes and might be useful as a functional diet for human diabetic diseases.

  • This study is intended to research female university students' concern with beauty care, their skin condition, knowledge and treatment comparing the majors with the non-majors in Seoul. This comparative study between them focused on their educational and behavioral differences in beauty care in the same living space, and the results were as follows: The majors' average point on the concern with skin health care was higher than the non-majors(p<.01). There were more combination skin type in the major group, and more dry skin type in the non-major group. Also, there were meaningful differences among the two groups in frequency of double cleansing after makeup, exfoliating, massaging or applying mask packs, using sunscreen(p<.01, p<.001, p<.01, p<.01). Further, intake rates of instant food and moisture were meaningfully different between them(p<.001, p<.05). In addition, the majors more tended to purchase cosmetics efficiently through lots of channels, and showed more active attitude to buy high-price cosmetics with outstanding properties although they have financial burden(p<.001). It was hoped that the results of this study would be used in skin care industry and education area in the future.

  • Objective: This study investigated the effects of feeding anthocyanin-rich black cane treated with ferrous sulfate and molasses on animal performance, rumen fermentation, microbial composition, blood biochemical indices, and carcass characteristics in meat goats. Methods: Thirty-two Thai-native×Anglo-Nubian crossbred male goats (14.47±2.3 kg) were divided equally into two groups (n = 16) to investigate the effect of feeding diet containing 50% untreated anthocyanin-rich black cane silage (BS) vs diet containing anthocyaninrich black cane silage treated with 0.03% ferrous sulfate and 4% molasses (TBS) on average daily gain (ADG) and dry matter intake (DMI). At the end of 90 d feeding trial, the goats were slaughtered to determine blood biochemical indices, rumen fermentation, microbial composition, and carcass characteristics differences between the two dietary groups. Results: Goats fed the TBS diet had greater ADG and ADG to DMI ratio (p<0.05). TBS diet did not affect rumen fluid pH; however, goats in the TBS group had lower rumen ammonia N levels (p<0.05) and higher total volatile fatty acid concentrations (p<0.05). Goats in the TBS group had a higher (p<0.05) concentration of Ruminococcus albus but a lower (p<0.05) concentration of methanogenic bacteria. The TBS diet also resulted in lower (p<0.05) thiobarbituric acid-reactive substances concentration but higher (p<0.05) total antioxidant capacity, superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase concentrations in blood plasma, while having no effect on plasma protein, glucose, lipid, immunoglobin G, alanine transaminase, and aspartate aminotransferase. Meat from goats fed the TBS diet contained more intramuscular fat (p<0.05) and was more tender (p<0.05). Conclusion: In comparison to goats fed a diet containing 50% untreated anthocyanin-rich black cane silage, feeding a diet containing 50% anthocyanin-rich black cane silage treated with 0.03% ferrous sulfate and 4% molasses improved rumen fermentation and reduced oxidative stress, resulting in higher growth and more tender meat.

  • Objective : This study was intended to examine the effects of water extract of Prunellae Spica (PS), which is a herb with 'cold' nature based on hot and cold theory of traditional Korean medicine. Methods : Hyperthyroidism was induced in SD rats by LT4 (0.5 mg/kg, i.p.) daily for four weeks. After 2 weeks of LT4 injection, rats were divided randomly into four groups; normal, LT4-induced hyperthyroid control, PS extract (500 mg/kg, p.o.)-treated group, and propylthiouracil (PTU, 10 mg/kg, s.c.)-treated positive group. After 2 weeks of drug treatment, all rats were sacrificed and harvested blood samples and thyroid tissues. The changes of body weight, food and water intake, and body temperature were measured weekly. Serological markers were analyzed in sera using an enzyme-based assay, and thyroid tissues were stained with Hematoxylin & Eosin (H&E). Brain and dorsal root ganglion (DRG) tissues were isolated and analyzed the expression of transient receptor potential (TRP) channels by Western blot. Results : PS extract administration attenuated the loss of body weight and the increase of body temperature in LT4-induced hyperthyroidism rats. PS extract increased the level of thyroid stimulating hormone (TSH) and decreased tiiodothyronine (T3) and tetraiodothyronine (T4). In action mechanism, PS extract regulated the expression of transient receptor potential channel subfamily V member 1 (TRPV1) and transient Receptor Potential channel subfamily M member 8 (TRPM8), the thermoregulators. Conclusion : To conclude, PS extract can improve the symptoms of hyperthyroidism through regulation of the thyroid hormones imbalance and thermoregulation via TRP channels.
