  • The aim of this study was to investigate whether a novel formulation of an herbal extracts has an inhibitory effect on obesity. To determine its anti-obesity effects, we performed anti-obesity-related experiments in vitro and in vivo. Thus, our present study was carried out to evaluate the anti-obesity effect of herbal extracts using a high fat diet (HFD)-induced obese mouse model and 3T3-L1 adipose cells. The effects of each herbal extracts on lipid accumulation in 3T3-L1 cells were examined using Oil Red O staining. Results showed that treatment with each herbal extracts at $10{\sim}100{\mu}g/ml$ had no effect on cell morphology and viability. Without evidence of toxicity, herbal extracts treatment decreased lipid accumulation compared with the untreated adipocytes controls as shown by the lower absorbance of Oil Red O stain. Futhermore, compared with control-differentiated mature adipocytes, each herbal extracts significantly inhibited lipid accumulation in mature 3T3-L1 adipocytes. In the HFD-fed obese mice, body weight, liver weight and white adipose tissue weights were significantly reduced by mixture of herbal extracts administration in mouse skin. Futhermore, we found that mixture of herbal extracts administration suppressed serum triglyceride (TG), and total cholesterol (TCHO) in HFD-induced obese mouse model. The mixture of herbal extracts of permeability was estimated by measuring the transepithelial electrical resistance (TEER) value in pig skin. The optimized formulations of herbal extracts (Test 3 formulation) showed skin permeation. However, test 1 formulation containing essential oil as enhancer showed maximum skin permeation. After confirming the enhanced skin permeability, in vivo studies were performed to assess whether skin irritation potential on the basis of a primary irritation index (PII) in rabbit skin. Reactions were scored for erythema/edema reactions at 24 h, 48 h and 72 h post-application. It was concluded that the test 1 formulation was not irritation (PII = 0). The present study suggests that the test 1 formulation might be of therapeutic interest with respect to the treatment of obesity.

  • The purpose of this study is to investigate the Ku which was worn by nomadic tribes which was Khitai, Mongols and Manchus. The results of this study can be summarized as follows. 1. The fur clothes were very important clothes that nomadic tribes put on in order to protect them against the cold. The Ku was an outfit for protection against the cold. It was made of ani-mal fur and its style was tight sleeve and long dress. 2. The Ku was worn in all social classes including emperor, nobles and the masses in ancient China and Asia dynasty. After the nomadic tribes estabilished dynasty in China the style of Ku was changed. All kinds of animal fur was used to make the Ku but the volume of fur, kinds and colors were classified severely by their social position. In Khitai dynasty the Ku was worn in same style. But the emperor wore the Ku of silver marten. The noble class wore the Ku of purple, black and blue marten and silver squirrel skin. The masses wore the Ku of the other colors marten, sheep, squirrel and dessert fox skin. In Mongol dynasty, the emperor wore the Ku of purple marten, silver squirrel, silver fox and black fox skin. The nobles wore the Ku of the other colors marten and squirrel. The masses wore the Ku of degraded animal fur. Before the Manchus estabilished the varient races dynasty in China, the rich man preferred the Ku of marten, squirrel, fox, goat furs. But the poorman preferred the Ku of cow, horses, pig, sheep, cat, dog, snake and deer skin. After the manchus conquered the China, the manners of dress were changed. Generally the fur did not appear in right side of garment, but high quality or noble fur appeared outside. Sometimes the inside or outside of Ku was made of silk fabrics and sleeves, neck-band was made of the high quality fur.

  • Hydrated liquid crystalline vesicles incorporating a edge activator, which confers flexibility to the vesicle membranes, were prepared and niacinamide was encapsulated in them. The formation of liquid crystalline phases and their thermal phase transitions were investigated by polarized optical microscopy and differential scanning calorimetry (DSC), respectively. Droplet sizes of the vesicles were reduced to several tens of nanometers by incorporating edge activators, such as sodium deoxycholate, lysolecithin, or polysorbate 80. The amount of niacinamide permeated into a pig skin increased greatly using the hydrated liquid crystalline vesicles compared to the case where niacinamide was applied in an aqueous solution state. The vesicles incorporating 10% sodium deoxycholate increased the amount of niacinamide permeated nearly four times. These results suggest that edge activators are effective in improving the skin permeability of vesicles.

  • Objective: The study was carried to determine the interaction effects of pen enrichment and sex on behavioral activities, skin lesions and physiology of Windsnyer pigs. Methods: Forty-eight growing Windsnyer pigs of both sex, with an average initial body weight of 21.6 (${\pm}9.01$) kg were used. Four pigs were randomly assigned to either enriched or barren pens at a stocking density of $0.35m^2/pig$. Enriched pens contained 2 L bottles filled with stones and suspended at head level on ropes stretching across the pens. In addition, two plastic balls (90 mm in diameter) and 500 mL bottles (235 mm long) were placed on the floor of each enriched pen. Results: Pigs in barren environments had higher heart rates (p<0.001) than those in enriched pens. There was an interaction of pen environment and sex on rectal temperature (p<0.001). Females in enriched pens had higher rectal temperatures (p<0.05) than females in barren pens. There was no interaction of pen environment and sex on time spent eating and drinking (p>0.05). Time spent bullying was influenced (p<0.05) by pen environment and sex. Female pigs in barren environment spent more time on bullying than females in enriched pens. There was an interaction of pen environment and sex on time spent lying down and walking (p<0.05). Female pigs in enriched pens spent more time lying down than females in barren pens. Males in barren pens spent more time walking than males in enriched pens while no effect of pen environment was observed in females. There was an interaction of pen environment and sex on the number of skin lesions in the head, neck and shoulder region and other parts of the body (p<0.05). Conclusion: It was concluded that pen enrichment reduced the number of skin lesions and anti-social behaviors, especially for female pigs. There is a need, therefore of housing indigenous pigs under confinement.

  • A trial was conducted to determine the effect of abrasive strips and abrasive paint in layer cages on claw length and claw sharpness, foot condition, feather cover and mortality of hens. During the preparation of the cages for the experiment it was simpler and took less time to apply the pre-prepared paint with a spatula to the egg guard compared to sticking the abrasive strips onto the egg guard. Fitting the strips took longer because it had to be cut from a 25 mm roll, cut into the appropriate lengths, the tape backing removed and then stuck onto the egg guard section. Abrasive paint was more effective as a claw shortener than abrasive strips. The birds using the abrasive paint had the shortest (p<0.05) claw length and lowest (p<0.05) claw sharpness. One of the original reasons for reducing claw length with claw shorteners was to reduce mortality by minimising skin skin abrasions caused by the claws. Surprisingly hen mortality from prolapse and cannibalism was higher (p<0.05) in cages fitted with abrasives. There are no other reports in the literature showing an increase in prolapse and cannibalism from hens using abrasives.

  • Collagen is the major structural protein of connective tissues. It can be used as a prosthetic biomaterial applicable to artificial skin, tendon, ligaments, and collagen implants. The objective of this study is to investigate the possibility of realizing wound dressing medical products by the synthesis of composite materials with collagen and a biodegradable polymer, PLLA, via a surface modification process. Type I collagen was obtained from pig skin by a separation process. The structural characteristics of the extracted collagen were confirmed by SDS-polyacrylamide (PAcr) gel electrophoresis (PAGE) and FTIR. Also, PLLA-g-PAcr was synthesized by the radical polymerization of acrylamide initiated by AIBN in the presence of PLLA. The surface of PLLA was modified by the presence of the acrylamide residues. The structural characteristics of the copolymer were analyzed by FTIR, $^1H-NMR$ and contact angle measurements. The water uptake and WVTR of the collagen/PLLA-g-PAcr composite tended to increase with increasing collagen concentration and with decreasing EDC concentration.

  • A review was undertaken to obtain information on the sustainability of pig free-range production systems including the management, performance and health of pigs in the system. Modern outdoor rearing systems requires simple portable and flexible housing with low cost fencing. Local pig breeds and outdoor-adapted breeds for certain environment are generally more suitable for free-range systems. Free-range farms should be located in a low rainfall area and paddocks should be relatively flat, with light topsoil overlying free-draining subsoil with the absence of sharp stones that can cause foot damage. Huts or shelters are crucial for protecting pigs from direct sun burn and heat stress, especially when shade from trees and other facilities is not available. Pigs commonly graze on strip pastures and are rotated between paddocks. The zones of thermal comfort for the sow and piglet differ markedly; between 12-22$^{\circ}C$ for the sow and 30-37$^{\circ}C$ for piglets. Offering wallows for free-range pigs meets their behavioural requirements, and also overcomes the effects of high ambient temperatures on feed intake. Pigs can increase their evaporative heat loss via an increase in the proportion of wet skin by using a wallow, or through water drips and spray. Mud from wallows can also coat the skin of pigs, preventing sunburn. Under grazing conditions, it is difficult to control the fibre intake of pigs although a high energy, low fibre diet can be used. In some countries outdoor sows are fitted with nose rings to prevent them from uprooting the grass. This reduces nutrient leaching of the land due to less rooting. In general, free-range pigs have a higher mortality compared to intensively housed pigs. Many factors can contribute to the death of the piglet including crushing, disease, heat stress and poor nutrition. With successful management, free-range pigs can have similar production to door pigs, although the growth rate of the litters is affected by season. Piglets grow quicker indoors during the cold season compared to outdoor systems. Pigs reared outdoors show calmer behaviour. Aggressive interactions during feeding are lower compared to indoor pigs while outdoor sows are more active than indoor sows. Outdoor pigs have a higher parasite burden, which increases the nutrient requirement for maintenance and reduces their feed utilization efficiency. Parasite infections in free-range pigs also risks the image of free-range pork as a clean and safe product. Diseases can be controlled to a certain degree by grazing management. Frequent rotation is required although most farmers are keeping their pigs for a longer period before rotating. The concept of using pasture species to minimise nematode infections in grazing pigs looks promising. Plants that can be grown locally and used as part of the normal feeding regime are most likely to be acceptable to farmers, particularly organic farmers. However, one of the key concerns from the public for free-range pig production system is the impact on the environment. In the past, the pigs were held in the same paddock at a high stocking rate, which resulted in damage to the vegetation, nutrient loading in the soil, nitrate leaching and gas emission. To avoid this, outdoor pigs should be integrated in the cropping pasture system, the stock should be mobile and stocking rate related to the amount of feed given to the animals.

  • Background : Long abscess is an accumulation of pus within a destroyed portion of the lung. Antibiotic therapy and postural drainge has proven to be an effective method of treatment for the majority of patients with pyogenic lung abscess. When medical therapy fails, thoracotomy and pulmonary resection are the current therapies. empyema is pus in the pleural space, and this term is deserved for effusions on which the Gram stain of the pleural fluid is positive. Initially, such collection may be drained via chest tribe. Recently, in patients who are judged to be unsuitable for surgery are in poor condition, percutaneous drainage using pig-tail catheter has been performed. We report out experience with 10 cases of lung abscess and 23 cases of empyema who were treated by percutaneous pit-tail catheter drainage. Subjects and Methods : Our study included 10 patients with lung abscess and 23 patients with empyema who were treated by percutaneous pig-tail catheter drainage, from January, 1990, to May, 1996, at Hanyang University then a pig-tail catheter was inserted into the abscess or the site of empyema under fluoroscopic and ultrasonograpic guidance. Following aspiration, the catheter was sutured into the skin, and connected to the suction tip. Catheter drainage was discontinued when the abscess of empyema was resolved in radiologically and clinically. Results : There were 2 cases of lung abscess caused by Staphylococcus aureus and Klebsiella pneumoniae and 14 cases of empyema caused by M. tuberculosis. The others were unknown. The duration of drainage was 1-2 weeks in 7 cases of lung abscess and 14 cases of empyema. In the 29 of 33 patients, percutaneous drainage were carried out successfully 20 of the 29 Gases rapidly improved. Conclusion : Percutaneous drainge is effective and relatively saute for management of lung abscess or empyema refractory to medical therapy or poor candidates for surgical treatment.

  • We evaluated the physicochemical and storage characteristics of Hanwoo Tteokgalbi treated with onion skin powder (OSP) and blackcurrant fruit powder (BFP). The experimental design included seven treatments: a control (ascorbic acid 0.1%), T1: OSP 0.3%, T2: OSP 0.6%, T3: BFP 0.3%, T4: BFP 0.6%, T5: OSP 0.15%+BFP 0.15%, and T6: OSP 0.3%+BFP 0.3%. The OSP was higher in both polyphenol and flavonoid contents compared to BFP (p<0.05). The moisture and ash contents of all Tteokgalbi samples with a large amount of added natural antioxidant powder (0.6%) were higher than those with small amounts of added antioxidant (0.3%). The cooking loss and water holding capacity were outstanding in the T2 treatment compared to the others (p<0.05). The lightness, redness, and yellowness values were reduced on the addition of 0.6% antioxidant powder (p<0.05). The springiness and cohesiveness values of the Tteokgalbi samples were higher for the 0.3% addition than the control and 0.6% addition (p<0.05). The Tteokgalbi samples with natural antioxidants showed similar sensory attribute scores compared to the control. The pH values reduced as the BFP increased (p<0.05), and the total microbial count increased after OSP addition. The 2-thiobarbituric acid reactive substance values of the samples treated with OSP were significantly lower than the control after day 10 (p<0.05). As a result, the addition of OSP or BFP did not have a significant negative influence on the quality characteristics of Hanwoo Tteokgalbi. In particular, the addition of 0.6% OSP was effective in increasing water retentivity and inhibiting lipid oxidation.

  • Objective: Piglet pre-weaning mortality is an important variable indicating the efficacy of farrowing management and animal well-being during lactation. The present study determined the association of newborn traits measured soon after birth with piglet pre-weaning mortality and growth. Methods: In total, 805 piglets born from 57 multiparous sows were investigated. Their blood oxygen saturation, blood glucose and rectal temperature at 24 h after birth (RT24h) were monitored. Birth order, sex, skin color, integrity of the umbilical cord, attempts to stand and birth intervention were monitored. Piglets were weighed at day 0, 7, and 21 to evaluate average daily gain (ADG). Results: Piglet pre-weaning mortality for lactation period was 12.6% and cumulative mortality during the first 7 days of age was 8.6%. A higher proportion of piglets with pale skin color died compared to piglets with normal skin color (26.7% vs 7.7%, p<0.001). A higher (p<0.001) proportion of piglets that attempted to stand after 5 min (38.5%) died compared to piglets that attempted to stand within 1 min (6.3%) after birth. Piglet body weight at birth ($BW_B$), blood glucose and the number of piglets born alive (BA) were correlated with ADG (p<0.05). Piglets with $BW_B$ <1.30 kg had higher (p<0.001) mortality rate than piglets with $BW_B{\geq}1.80 kg$ (19.0% vs 3.3%) and piglets with $BW_B$ 1.30 to 1.79 kg (4.0%). Piglet with RT24h <$37.0^{\circ}C$ had higher (p<0.001) mortality rate (86.2%) than piglets with RT24h >$38.5^{\circ}C$ (3.9%). Conclusion: Low $BW_B$ and low RT24h compromise piglet survival during the lactation period in the tropical conditions. Piglets in the litters with a high BA, low $BW_B$ and low blood glucose have reduced ADG.
