Purpose: We investigated the efficacy of electroacupuncture therapy in obese Korean women in order to make basic guidelines for the use of oriental medicine in treating obesity. Methods: Forty women were divided into two groups and each was treated 12 times: 1) one group was treated using electroacupuncture (EA) involving auricular acupuncture and physical treatment, without exercise (EA group, n=10), and 2) the other group was treated using electroacupuncture and exercise (EA plus exercise group, n=30). The EA was applied to subcutaneous fat tissue manually. Body weight was evaluated every visit and body composition was checked at the $1^{st}$ and $12^{th}$ visits. Statistical comparisons were made using SPSS13.0. We compared the weight loss, body mass index (BMI), and body composition before and after treatment using the pairedt-test. The correlations between weight loss and BMI and age were examined. Results: After the $12^{th}$ treatment, both groups showed significant reductions in body weight, BMI, body fat, and body fat percentage. The weight loss averaged 4.58${\pm}$3.87% in the EA group and 4.69${\pm}$3.10% in the EA plus Exercise group. The reduction in skeletal muscle was significant in the EA group, but not significant in the EA plus Exercise group. The speed of the weight loss was correlated with age using Pearson's correlation coefficient. Based on BMI, normal and obese subjects in the EA plus Exercise group had significant reductions in body weight, BMI, body fat, and body fat percentage; the obese subjects also had a significant reduction in skeletal muscle. Conclusion: Combined EA therapy may be effective for weight reduction. Age and BMI were related to weight loss using EA therapy.

A total of 40 Korean native pigs (gilt 21, boar 19) were used to investigate the meat quality, nutritional and sensory properties by gender. Gilts had significantly lower moisture and ash contents (%) than boars, but protein contents were not significantly different between the gender (p<0.05). Gilts contained high intramuscular fat contents were significantly lower in Warner-Bratzler shear force (WBS) and Water holding capacity (WHC) when compared to those of boars. There was no significant difference in meat color L (lightness) and a (redness) values between the gender (p>0.05), but gilt had higher b (yellowiness) values than boar. Regarding amino acid compositions, there were glutamic acid (3.25%), aspartic acid (1.94%) lysine (1.83%), leucine (1.77%), alanine (1.17%) and arginine (1.15%) for gilts and boars. There were no significant differences in the contents of the minerals such as calcium, potassium, phosphorous, sodium, magnesium, iron, zinc and copper (p>0.05). The results of fatty acid composition showed that gilts had significantly higher C16:1n7, C18:1n9, in intramuscular fat., whereas they had significantly higher contents of C14:0, C16:0, C20:1n9, C20:5n3 in subcutaneous fat than boars (p<0.05). Boars had significantly higher contents of C18:0, C18:1n7, C18:2n6, C20:1n9, C20:4n6, C22:4n6 in intramuscular fat and they had significantly higher contents of C18:2n6, C22:4n6 than gilts in subcutaneous fat (p<0.05). In sensory evaluation, gilts had significantly higher scores in juiciness, tenderness and flavor when compared to boars (p<0.05).

Objective: Excessive lipid accumulation in adipocytes results in prevalence of obesity and metabolic syndrome. Curcumin (CUR), a naturally phenolic active ingredient, has been shown to have lipid-lowering effects. However, its underlying mechanisms have remained largely unknown. Therefore, the study aims to determine the effect of CUR on cellular lipid accumulation in porcine subcutaneous preadipocytes (PSPA) and to clarify novel mechanisms. Methods: The PSPA were cultured and treated with or without CUR. Both cell counting Kit-8 and lactate dehydrogenase release assays were used to examine cytotoxicity. Intracellular lipid contents were measured by oil-red-o staining extraction and triglyceride quantification. Apoptosis was determined by flow cytometry and the terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-nick end labelling assay. Adipogenic and apoptosis genes were analyzed by quantitative polymerase chain reaction and Western blot. Results: The CUR dose-dependently reduced the proliferation and lipid accumulation of PSPA. Noncytotoxic doses of CUR (10 to 20 μM) significantly inhibited extracellular signal-regulated kinase 1/2 (ERK1/2) phosphorylation and expression of adipogenic genes peroxisome proliferation-activity receptor-γ (PPAR-γ), CCAAT/enhancer binding protein-α, sterol regulatory element-binding protein-1c, adipocyte protein-2, glucose transporter-4 as well as key lipogenic enzymes fatty acid synthase and acetyl-CoA carboxylase, while ERK1/2 activation significantly reversed CUR-reduced lipid accumulation by increasing PPAR-γ. Furthermore, compared with differentiation induced media treated cells, higher dose of CUR (30 μM) significantly decreased the expression of AKT and B-cell lymphoma-2 (BCL-2), while increased the expression of BCL-2-associated X (BAX) and the BAX/BCL-2 expression ratio, suggesting triggered apoptosis by inactivating AKT and increasing BAX/BCL-2 ratio and Caspase-3 expression. Moreover, AKT activation significantly rescued CUR inhibiting lipid accumulation via repressing apoptosis. Conclusion: These results demonstrate that CUR is capable of suppressing differentiation by inhibiting ERK1/2-PPAR-γ signaling pathway and triggering apoptosis via decreasing AKT and subsequently increasing BAX/BCL-2 ratio and Caspase-3, suggesting that CUR provides an important method for the reduction of porcine body fat, as well as the prevention and treatment of human obesity.

Two separate trials were designed to determine effects of dietary level of whole flaxseed (WFS) on fatty acid composition of serum, and subcutaneous, perirenal, intermuscular, and intramuscular adipose tissues of Korean Hanwoo cattle. Twentyone bulls (trial 1) and 15 cows (trial 2) were assigned to diets containing 0, 10 or 15% WFS. Relative treatment effects were similar between bulls and cows. The proportion of C18:3 in serum and to a lesser extent in adipose tissues were increased by dietary inclusion of WFS, reflecting supplemented lipid composition of WFS that escaped ruminal biohydrogenation. Animals fed WFS had a lower proportion of saturated fatty acids in serum and adipose tissues than animals fed diets without WFS, while the opposite trend was observed in unsaturated fatty acids with little differences between two WFS groups. WFS-fed animals had higher proportions of C18:1, 18:2, 18:3, 20:3, and 22:3 and lower proportions of C12:0, 14:0, 16:0 and 18:0 in intramuscular fat than animals fed diets without WFS. Furthermore, feeding WFS increased proportions of both $\omega$-3 and $\omega$-6 fatty acids but decreased the ratio of $\omega$-6/$\omega$-3 substantially. In conclusion, feeding WFS can be an effective method of increasing absorption of unsaturated fatty acids, and subsequent deposition in adipose tissues.

The purpose of this study was to determine the incidence of malnutrition among patients on admission to hospital, to monitor changes in their nutritional status during hospitalization, and to determine the factors which might affect changes in nutritional status. The subjects for the study were patients who were admitted to general medicine for more than one week. Patients suffering from cardiovascular. renal disease, or dehydration were excluded. Nutritional assessment of the patients was performed on admission and nutritional status was reassessed one week and two weeks after admission. The nutritional assessment tool consisted of subjective history taking and anthropometric measurements. Biochemical measurements were performed only on admission. For anthropometric assessment : patients' body weight, subcutaneous skinfolds thickness, % of body fat, body mass index, and lean body mass were measured using caliper or Bio impedance Analyzer. Factors which might influence current nutritional status, like dietary intake, anorexia, nausea, vomiting, diarrhea, sleep disturbance, and number of days of NPO for diagnostic examinations were analyzed. The results are as follows : 1. Of the 59 patients who were studied, 61% were male and 39% female. The nutritional status of all of the 59 subjects was reassessed one week after admission, but it was only done for 22 subjects at two weeks. 2. The anthropometric measurements. including weight body mass index, lean body mass, body fat. and skin fold thickness. were all significantly decreased at one week after admission compared to the values at admission. On the other hand, two weeks after admission, only body weight and abdominal skinfolds thickness were decreased. 3. The subjects reported anorexia for an average of two days, sleep disturbance for two days, and no food intake due to diagnostic test for one day. In the second week of hospitalization, almost none of the patients complained of gastrointestinal symptoms or sleep disturbance except anorexia. Food consumption which was measured based on rice intake was 60% of the food served during the first week of hospitalization, and 66% during the second week of hospitalization. 4. There was no correlation between the subjective nutritional assessment and anthropometric assessment. 5. There was no statistical significance in anthropometric measurements among the patients with various diseases whereas sleep disturbance and no food intake due to various diagnostic test was prominent in patients with gastrointestinal diseases.

Purpose: Sclerosing lipogranuloma is an unusal benign condition of the genitalia following injections into the genitalia with exogenous paraffin or mineral oil. A few cases have been reported in which sclerosing lipogranuloma of the lid was caused by paraffin-containing ointment plugs after the endonasal sinus surgery. A 52-year-old man presented with a painless hard mass of the right lower lid after the MRI scan at the Ophthalmology department. Nine months before, he had undergone right maxilla sinus surgery through the oral incision. And he was also gotten nasal packing with Vaseline gauze after the surgery. Methods: The round shaped two masses in the Right lower lid were approximately $1.0{\times}1.0cm$ in size. There were no size or color change, bleeding and ulceration. The MRI scan showed a suspicious part of an abscess of benign tumor. Also, He was planned cyst remove through the endonasal surgery due to the mucoid cyst in the right maxillary sinus in the ENT dept. Under the general anesthesia, the patient underwent surgical excision through a subcilliary incision with endonasal sinus surgery. The masses were in deep subcutaneous orbital fat with no connection with right maxillary sinus. Results: The masses were excised $2.1{\times}0.7cm$ in size including surrounding necrotic fatty tissue. Histopathological diagnosis was 'sclerosing lipogranuloma' due to paraffin or similar substance with fat necrosis and cystic change. This tissue was positive in PAS, S-100, CD68 reaction. Conclusion: It is extremely rare to find a granulomatous orbital lesion arising to a endonasal surgery. In conclusion, if sclerosing lipogranuloma is suspected excisional biopsy should be undertaken. Surgery should be reserved for recurrent or refractory cases when steroids have failed as first-line treatment at the 6-month follow-up examination, There was no complication or recurrence.

This research was conducted to investigate the physiological consequences of undernourished yak. Twelve Maiwa yak ($110.3{\pm}5.85kg$) were randomly divided into two groups (baseline and starvation group). The yak of baseline group were slaughtered at day 0, while the other group of yak were kept in shed without feed but allowed free access to water, salt and free movement for 9 days. Blood samples of the starvation group were collected on day 0, 1, 2, 3, 5, 7, 9 and the starved yak were slaughtered after the final blood sample collection. The liver and muscle glycogen of the starvation group decreased (p<0.01), and the lipid content also decreased while the content of moisture and ash increased (p<0.05) both in Longissimus dorsi and liver compared with the baseline group. The plasma insulin and glucose of the starved yak decreased at first and then kept stable but at a relatively lower level during the following days (p<0.01). On the contrary, the non-esterified fatty acids was increased (p<0.01). Beyond our expectation, the ketone bodies of ${\beta}$-hydroxybutyric acid and acetoacetic acid decreased with prolonged starvation (p<0.01). Furthermore, the mRNA expression of lipogenetic enzyme fatty acid synthase and lipoprotein lipase in subcutaneous adipose tissue of starved yak were down-regulated (p<0.01), whereas the mRNA expression of lipolytic enzyme carnitine palmitoyltransferase-1 and hormone sensitive lipase were up-regulated (p<0.01) after 9 days of starvation. The phosphoenolpyruvate carboxykinase and pyruvate carboxylase, responsible for hepatic gluconeogenesis were up-regulated (p<0.01). It was concluded that yak derive energy by gluconeogenesis promotion and fat storage mobilization during starvation but without ketone body accumulation in the plasma.

To understand molecular mechanisms that regulate deposition and release of intramuscular fat, a fasting-induced clone was identified by differential screening from cDNA library of adipose tissues of Korean cattle. The clone had a total length of 1,319 nucleotides coding for 334 amino acids. It was identified as one encoding L-lactate dehydrogenase H chain (LDH-B). Comparison of the deduced amino acid sequences of bovine LDH-B with those of pig, human, rat, and mouse showed 98%, 98%, 97%, and 96% identity, respectively. Food deprivation for 48 h increased mRNA levels of LDH-B gene in adipose tissues of Korean cattle compared to fed- and 6 h refed- tissues. The expression of obese mRNA was examined for individual adipose tissue from several fat depots. Fasting induced expression of LDH-B gene in subcutaneous adipose tissues, but it did not affect expression levels in abdominal, perirenal and intramuscular tissues. Results demonstrate that induction of LDH-B gene during fasting may represent a metabolic shift from anaerobic state to aerobic predominance in fasted adipose tissues and that its responses to fasting are different among several adipose tissues.

The objective of this study was to determine age-related changes in the percentage content of edible and non-edible components in broiler chickens. The experimental materials comprised 240 Ross 308 chicks (sex ratio 1:1) raised to 10 weeks of age and fed standard diets ad libitum. Starting from the first week of rearing, every 7 days 10 males and 10 females were selected randomly for slaughter and post-slaughter analysis. The data obtained were verified statistically. The percentage content of edible components increased and the percentage content of non-edible parts decreased as the chicks grew older. In broilers aged 1 week and 10 weeks, edible components accounted for 47.0% and 66.4% total body weight, respectively. The share of muscle tissue increased considerably over this period, from 30.9% total body weight in week 1 to 52.4% in week 10. An increase in the percentage of skin and subcutaneous fat was observed for the first three weeks only, while the percentage content of giblets (in contrast to the remaining edible parts) decreased with age. For non-edible parts, the share of bones diminished by 2.5% and the proportion of slaughter offal reduced by 13.8%. A rising tendency was noted with respect to feathers and abdominal fat, while the content of the remaining offal decreased.

Three dogs presented to the Veterinary Medical Teaching Hospital of the University of Konkuk and Hangang Animal Hospital with a history of perineal swelling. No tenesmus, stranguria, or any clinical signs other than the swelling was observed by the owners in three dogs. On physical examination, the swelling was observed unilaterally in two dogs and bilaterally in a dog. Digital palpation to the swelling confirmed reducible perineal herniation in two dogs and irreducible perineal herniation in a dog. Plain radiographs revealed that no pelvic or abdominal contents other than the fat were displaced into subcutaneous perineal region in three dogs. Internal obturator transposition herniorrhaphy was performed for correction of perineal herniation in three dogs. Contralateral herniation involving fat was noted after surgery in a dog. The follow-up information was based on physical examination by veterinarians or telephone interview with owners. The owners reported that there was no evidence of complications related to surgery such as sciatic nerve injury, rectal prolapse, wound dehiscence, or perineal hernia recurrence in all dogs.
