Poland씨 증후군과 관련된 흉벽기형은 매우 드문 질환으로 선천적으로 대흉근의 흉골부 결손과 한쪽 상지의 다양한 기형을 동반한다. 또한 Poland씨 증후군의 다른 임상적 특징은 유방과 유두의 결손 및 저형성, 피하 지방과 액모의 결손, 늑연골 및 늑골전면부의 이상을 포함한다. 그 기원은 확실하지 않으나 유전과는 관계 가 없는 것으로 알려져 있다. Poland씨 증후군은 심한 정신적인 그리고 신체적인 문제를 일으킬 수 있으며 초기 발견 및 수술적 교정이 이득이 될 것으로 생각된다. 본원은 Poland씨 증후군으로 진단된 37세 남자환자를 성공적으로 수술치험하였기에 이를 보고하는 바이다.

Objective: The objective of this study was to investigate the effects of various dietary unsaturated to saturated fatty acids ratios (UFA to SFA ratios) on growth performance, carcass traits, blood lipid parameters, tissue fatty acid (FA) composition, and meat quality of finishing pigs. Methods: A total of 45 crossbred pigs ([Duroc×Landrace]×Yorkshire), with an average initial body weight of 60.3±2.4 kg, were randomly allocated to three treatment groups of 1:1, 2:1, and 3:1 dietary UFA to SFA ratios. Results: Both average daily gain and average daily feed intake of pigs were decreased linearly (p<0.05), whereas backfat thickness was decreased linearly (p<0.05) with increasing of dietary UFA to SFA ratio. Serum triglyceride and low density lipoprotein cholesterol were decreased quadratically or linearly (p<0.05) respectively, whereas high density lipoprotein cholesterol was increased quadratically (p<0.05) with increasing dietary UFA to SFA ratio. In M. longissimus thoracis, the proportion of C18:1 and monounsaturated FA was decreased linearly (p<0.05), whereas the proportion of C18:2n-6, C20:4n-6 and polyunsaturated FA (PUFA) were increased linearly (p<0.05) as dietary UFA to SFA ratio increased. In the subcutaneous adipose tissue, the proportion of SFA was decreased linearly (p<0.05), whereas the proportion of n-6 PUFA, n-3 PUFA, and the UFA to SFA ratios were increased linearly (p<0.05) with increasing of dietary UFA to SFA ratio. Meat color scores and shear force of pigs were decreased linearly (p<0.05), whereas drip loss and cooking loss were increased linearly (p<0.05) with increasing of dietary UFA to SFA ratio. Conclusion: Appropriately boosted dietary UFA to SFA ratio could be conductive to optimize blood lipid parameters and tissue FA composition. However, when the ratio is too high or too low it tends to have negative effects on growth performance and meat quality.

Background and Objectives : Necortizing fasciitis in the cervical region is a very rare disease with high mortality and morbidity rates. The purpose of this study was to analyze the clinical characteristics, treatment results, complication and prognosis of necrotizing fasciitis patients. Materials and Methods : We retrospectively reviewed the inpatient charts treated for cervical necrotizing fasciitis at our Otorhinolaryngology clinic. We diagnosed necrotizing fasciitis by the clinical findings such as swelling, redness and pain of infected area and necrosis of subcutaneous fat layer and fascia observed during surgery. Twenty such patients were identified and treated from January 2011 to December 2016. Results : 20 adults consisting of 14 male and 6 females with cervical necrotizing fasciitis were diagnosed and treated. The most commonly known associated preceding illness were dental abscess and tonsillitis. The most pathogen was Streptococcus species (12/20), followed by Klebsiella pneumonia (6/20), Staphylococcus species (2/20). The mean duration of hospitalization was 32.2 days (range,14-86). The mean Modified Laboroatory Risk Indicator for Necrotizing Fasciitis (M-LRINEC) score is 7.4 and more than 4 points was eighteen. All patients received parenteral antibiotics and surgical drainage after admission. Conclusions : The reason for the high survival rate in the study was the early diagnosis, as well as the early surgical procedure and antibiotics. After the operation, frequent betadine irrigation could improve the patient's condition and recover without severe complication.

Objective: The aim of this study was to evaluate the effect of dietary incorporation of tanninrich woody species on meat oxidative stability, carcass traits and meat quality in goats. Methods: Two tannin-rich species were tested using a three-treatments feeding trial, where treatments consisted of: Larrea divaricata and Acacia aroma both at 12.5% in dry matter basis of the diet and a control diet (alfalfa hay). All feeding diets were iso-protein and iso-energy. Carcass conformation, carcass compactness, carcass fatness and subcutaneous fat deposition were evaluated. Intake, liveweigh, Longissimus thoracis et lumborum muscles of goats were analyzed in order to evaluate quality parameters such as pH value, instrumental color evaluation, water holding capacity, total phenolic content, antioxidant activity, meat oxidative stability and fatty acid profiles in meat. Results: Feed intake, liveweight gain, carcass, and meat traits did not differ among treatments. Changes in meat lipid profile among treatments were observed for oleic and elaidic acid contents. Meat total phenolic content and antioxidant activity did not differ among treatments; although, meat oxidative status after storage at room temperature, as well as under refrigerated and frozen conditions were different between control and both supplemented groups. Conclusion: The inclusion of Acacia aroma and Larrea divaricata leaves in goat diet enhanced meat oxidative stability. Modulation of the ruminal biohydrogenation of fatty acids produced by condensed tannins of these plant species need to be further investigated.

The tarsus in dogs has a complex structure that makes its evaluation relatively challenging. Because an accurate diagnosis of the tarsus is difficult through basic examinations alone, imaging tests are essential. Previous studies have explored the anatomical and radiological features of the canine tarsus using several imaging modalities. However, the imaging utility of the tarsus across different modalities has not been thoroughly evaluated. This study aimed to visualize the tarsal structures using magnetic resonance imaging (MRI) and ultrasonography, compare their utility, and propose suitable imaging modalities and conditions for evaluating specific tarsal structures. Magnetic resonance imaging and ultrasound scans of the tarsus of four healthy dogs were performed, and two observers rated the utility of each image on a five-point scale. Although MRI is more beneficial for assessing the tarsal structures than ultrasound, ultrasound also appears clinically useful for evaluating the cranial tibialis muscle, deep digital flexor tendon, subcutaneous fat, joint space, and superficial digital flexor tendon. In addition, each structure of interest can be evaluated for optimal visibility using specific ultrasound sections, MRI sequences, and planes. In veterinary clinical practice, an initial assessment using ultrasound imaging with optimal visibility is required and if further evaluation is necessary, MRI examinations with optimal MRI sequences and planes can be performed.

The study was carried out to evaluate the effect of exogenous bovine somatotropin on water metabolism in relation to mammary function in early lactation of crossbred Holstein cattle. Ten, 87.5% crossbred Holstein cattle were divided into two groups of 5 animals each. At day 60 of lactation, the control group was given placebo while animals in the experimental group were given recombinant bovine somatotropin (rbST) by subcutaneous injection with 500 mg of rbST (14-days prolonged-release rbST). In rbSTtreated animals, milk yield increased 19.8%, which coincided with a significant increase in water intake (p<0.01), while DM daily intake was not different when compared to the control animals. Water turnover rate as absolute values significantly increased (p<0.05), while the biological half-life of water did not change in rbST-treated animals. Total body water (TBW) and total body water space (TOH) as absolute values significantly increased (p<0.01) in rbST-treated animals, while it was decreased in the control animals. Absolute values of empty body water (EBW) markedly increased (p<0.05), which was associated with an increase in the extracellular fluid (ECF) volume. Absolute values of plasma volume and blood volume were also significantly increased (p<0.05) in rbST-treated animals. The increase in mammary blood flow in rbST-treated animals was proportionally higher than an increase in milk production. The plasma IGF-1 concentration was significantly increased (p<0.01) in rbST-treated animals when compared with those of control animals during the treatment period. Milk fat concentration increased during rbST treatment, while the concentrations of both protein and lactose in milk were not affected. The present results indicate that rbST exerts its effect on an increase in both TBW and EBW. An increased ECF compartment in rbST-treated animals might partly result from the decrease in fat mass during early lactation. The action of rbST on mammary blood flow might not be mediated solely by the action of IGF-1 for increase in blood flow to mammary gland. An elevation of body fluid during rbST treatment in early lactation may be partly a result of an increase in mammary blood flow in distribution of milk precursors to the gland.

To study effect of non-fat components present in plant seeds on lipid metabolism, defatted safflower and perilla seed powders were used in high cholesterol diets for ovariectomized (ovx) female Sprague-Dawley rats weighing 227$\pm$15g. Experimental groups were six as follows; normal group without ovariectomy and cholesterol-free diet, sham and ovx-control groups with high cholesterol and cellulose for dietary fiber, ovx-est group with the same diet as ovx-control but with eight subcutaneous injections of 50$\mu\textrm{g}$ 17$\beta$-estradiol. ovx-safflower and ovx-perilla with 29% and 16% (w/w) of each defatted powder in high cholesterol diets at the expense of cellulose. Weight gains were lower in normal and sham groups and food efficiencies were lower in normal,ovx-est and ovx-safflower groups compared with ovx-control. Uterus weights were dramatically reduced by ovariectomy but restored completely by 17$\beta$-estradiol and partially (~5%) by defatted safflower. Plasma levels of total cholesterol were not different among ovx-control, sham, vx-est and ovx-safflower groups (90.8~95.1 mg/dL) but that was lower in ovx-perilla (80.4$\pm$6.2 mg/dL). Plasma triglyceride (TG) levels were lower in sham (76.6$\pm$7.0 mg/dL) and ovx-perilla (79.2$\pm$5.8 mg/dL) groups. Liver cholesterol levels were lower in sham, ovx-est, ovx-safflower and ovx-perilla groups (26.6~29.8 mg/g) than ovx-control (36.5$\pm$3.2 mg/g). But liver TG levels were reduced only sham and ovx-est groups compared to control group. Fecal excretions of bile acid and cholesterol were highest in ovx-safflower group (30.8$\pm$5. and 32.1$\pm$5.7 mg/g) compared with other ovx groups (20.8~23.1 and 12.1~19.5 mg/g). These results suggest that both perilla and safflower seeds contain groups (20.8~23.1 and 12.1~19.5mg/g). These results suggest that both perilla and safflower seeds contain non-fat and non-fiber components having lipid lowering effects.

G protein-coupled receptor 43 (GPR43) is a newly-discovered short-chain free fatty acid receptor and its functions remain to be defined. The objective of this study was to investigate the function of GPR43 on lipolysis. We successfully cloned the GPR43 gene from the pig (EU122439), and measured the level of GPR43 mRNA in different tissues and primary pig adipocytes. The expression level of GPR43 mRNA was higher in adipose tissue and increased gradually with adipocyte differentiation. Then we examined GPR43 mRNA level in different types, growth-stages and various regions of adipose tissue of pigs. The results showed that the expression level of GPR43 mRNA was significantly higher in adipose tissue of obese pigs than in lean pigs, and the expression level also gradually increased as age increased. We further found that the abundance of GPR43 mRNA level increased more in subcutaneous fat than visceral fat. Thereafter, we studied the correlation between GPR43 and lipid metabolism-related genes in adipose tissue and primary pig adipocytes. GPR43 gene had significant negative correlation with hormone-sensitive lipase gene (HSL, r = -0.881, p<0.01) and triacylglycerol hydrolase gene (TGH, r = -0.848, p<0.01) in adipose tissue, and had positive correlation with peroxisome proliferator-activated receptor $\gamma$ gene ($PPAR_{\gamma}$, r = 0.809, p<0.01) and lipoprotein lipase gene (LPL, r = 0.847, p<0.01) in adipocytes. In addition, we fed different concentrations of docosahexaenoic acid (DHA) to mice, and analyzed expression level changes of GPR43, HSL and TGH in adipose. The results showed that DHA down-regulated GPR43 and up-regulated HSL and TGH mRNA levels; GPR43 also had significant negative correlation with HSL (low: r = -0.762, p<0.01; high: r = -0.838, p<0.01) and TGH (low: r = -0.736, p<0.01; high: r = -0.586, p<0.01). Our results suggested that GPR43 is a potential factor which regulates lipolysis in adipose tissue, and DHA as a receptor of GPR43 might promote lipolysis through down-regulating the expression of GPR43 mRNA.

Objective: Fresh sugarcane has been a new roughage source for ruminant's in semiarid regions, a function of the decline of sugar and alcohol industry in recent years. However, there is little data published regarding lambs fed sugarcane associated with spineless cactus. This study evaluated the effect of sugarcane replacement with spineless cactus (0%, 33%, 66%, and 100%) in the diet of Santa $In\hat{e}s$ lambs on carcass characteristics. Methods: Thirty-six non-castrated Santa Ines lambs at four months of age and an initial body weight of $22{\pm}2.3kg$ were assigned in a randomized block design and slaughtered after 70 days of confinement. The effects of spineless cactus as a replacement for sugarcane in the diet of the lambs on the carcass characteristics, commercial cut weight and yield, leg tissue composition, and carcass measurements were studied. Results: The study revealed quadratic behavior in slaughter body weight, and hot and cold carcass weight, with maximum values of 38.60, 18.60, and 18.11 kg and replacement levels of 40.18%, 44.42%, and 43.14%, respectively. The cold carcass yield presented an increasing linear behavior. The compactness index of carcass and leg presented a quadratic effect, with estimated maximal values of 0.28 and 0.57 kg/cm and replacement levels of 43.37% and 45.5%, respectively. The weights of commercial cuts of leg, loin, shoulder, and breast showed quadratic behavior, with maximum values of 2.79, 0.852, 1.46, and 1.30 kg and replacement levels of 49.5, 45.32, 39.0, and 40.7, respectively. For tissue composition, quadratic behavior was verified for leg weight, subcutaneous fat, and total fat. Conclusion: The replacement of sugarcane by spineless cactus at level 44% is recommended for finishing lambs considering that this level improved most of the carcass characteristics, weights, and yields of commercial cuts and leg tissue composition.

Ivermectin is a widely used broad spectrum antiparasitic agent in veterinary medicine. In this work, we examined the pharmacokinetic parameters and the tissue residue profile of a new injectable formulation of ivermectin developed for pigs. The plasma ivermectin levels reached the peak at about 9 and 2 hours after the administrations in young and adult pigs, respectively. But the elimination half-life (3-3.5 days) and the $C_{max}$ values (24~28 ng/ml) were not significantly different between young and adult pig groups. When compared to the reference formulation, the $C_{max}$ of test formulation was higher and $T_{1/2}$ values were shorter than those of the reference formulation, respectively. The tissue residue levels were dose- and time-dependent and were higher in the liver and fat, than in the other tissues such as the injection sites, the kidney, intestine, muscle, plasma (4~74 ng/g) at the 7th day after the administration of both formulations of ivermectin. Then, the mean tissue ivermectin levels at the 21st day after the administration in all the tissues decreased to 7.4 and 25% of the 7th day levels in the test and reference formulations, respectively. In general, the tissue levels of ivermectin in the animals treated with the test formulation decreased more rapidly than those with the reference formulation. The tissue to plasma distribution ratio (T/P ratio) of ivermectin was higher in the liver and fat than other tissues. The T/P ratio in the liver of animals treated with the test formulation was somewhat higher than that in the animals treated with the reference formulation. Taken together, the results of pharmacokinetic and tissue residue studies indicate that the test formulation of ivermectin for subcutaneous injection is comparable to the reference formulation, but unique in that it has higher peak plasma concentrations, shorter elimination half-life and higher T/P ratio in the liver than the reference formulation.
