  • Purpose: Even though Augmentation rhinoplasty is very popular surgical procedure, it is not easy to obtain ideal materials for augmentation. Many different synthetic materials are used but frequent complications are seen such as infection, extrusion, deform, and dislocation. Autologous tissues were used for augmentation rhinoplasty. We used dermofat graft and fat injection in augmentation rhinoplasty minimizing these problems. Methods: From 2006 to 2009, we used autologous tissues in augmentation rhinoplasty in 40 patients, 20 patients with dermofat graft and other 20 patients were treated with fat injection only. Dermofats were harvested from sacral area. gluteal fold, groin and preexisting scar tissue. Dermofats were inserted with small stab wound and fat tissues were injected as Coleman's technique. The patients were followed up 6 months to 5 years. Results: Most of the patients were satisfied in shape and height the nose. Early complications such as hematoma, infection and seroma were not found. Secondary fat injection was performed in 3 patients (15%) of dermofat graft group instead of 7 patients (35%) of fat injection only group. Conclusion: We obtained satisfactory results in augmentation rhinoplasty with dermofat graft and fat injection. Secondary fat injections were more often in fat injection group than dermofat graft group. Dermofat graft and fat injection could be another alternative technique for augmentation rhinoplasty and fat injection could be a secondary adjunctive treatment for undercorrection due to absorption.

  • Objetives This experimental study is designed to investigate the effects of kwakhyangjungkisangamibang extract on the changes of adipose tissues, serum insulin and leptin levels in rats induced by a high fat diet. The leptin has been proposed to be involved in the role of food intake and energy expenditure. Methods During the 8 weeks of experimental period, male Sprague-Dawley rats were fed on the 2 different diets: the normal diet AIN-76A and high fat(beef tallow) diet ad libitum, of which 40% of the calories intake was fat. 9 rats in the control and high fat diet group were killed for the baseline experiment at 4 weeks of age. The high fat diet group was divided into three groups: control group, experimental group I(high fat diet plus kwakhyangjungkisangamibang extract), and experimental group II(high fat diet plus mahuang). The body weight, hypodermal fat tissue, serum lipid profile, insulin and leptin levels were measured after the administration of the high fat diet and extract. Results 1. The body weight was decreased in experimental group II, but there was not a significance difference compared to the control group. 2. The peritoneal, visceral, and hypodermal adipose tissue was decreased in experimental group I, but there was not a significance difference compared to the control group. 3. The lipid profile was decreased in experimental group I, but not in group II. 4. The insulin concentration was increased in experimental group I and II, but there was not a significance difference compared to the control group. 5. The leptin level was increased significantly in experimental group I(p<0.05) and II(p<0.01) compared to the control group. Conclusion The results of this study indicate that kwakhyangjungkisangamibang has an effect on the regulation of obesity.

  • Objectives: We investigated the effects of Allii Fistulosi Bulbus (AFB) on high fat diet (HFD)-induced obesity in mice and the regulation of energy metabolism in muscle tissues of mice. Methods: The C57BL/6 mice (6 weeks, male) were fed a HFD for 8 weeks and then administrated with AFB extract at 500 mg/kg (p.o.) once daily for 4 weeks. The body weight (BW), muscle weight, calorie intake, fasting blood glucose (FBG) and serum glucose, insulin, and low-density lipoprotein-cholesterol (LDL-C) levels were measured in mice. It was also observed the histological changes of pancreas, liver, and fat tissues with hematoxylin and eosin staining. It was investigated the phosphorylation of insulin receptor substrate 1 (IRS-1), Ser/Thr kinase (AKT), and adenosine monophosphate-activated protein kinase (AMPK), and the expression of phosphoinositide 3-kinase, glucose transporter type 4 (GLUT4), and sirtuin1 (Sirt1) in gastrocnemius tissues by western blot, respectively. Results: The increases of BWs, calorie intakes and FBG levels in obesity mice were decreased significantly by the administration of AFB extract. The AFB extract administration was reduced significantly serum levels of glucose, insulin, and LDL-C in obesity mice. The AFB extract inhibited lipid accumulation in liver tissues, hyperplasia of pancreatic islets, and enlargement of fat tissues in obesity mice. The phosphorylation of IRS-1 and AKT was increased significantly in muscle tissues and AMPK phosphorylation and the GLUT4 and Sirt1 expression were decreased significantly in muscle tissues after the AFB administration. Conclusions: Our study indicates that AFB extract improves symptoms of obesity through regulation of energy regulating proteins in muscle tissues.

  • This study is concerned with the temperature dependence characteristics of ultrasound parameters in biological tissues, which are basic on the noninvasive deep body temperature estimation. Used parameters are ultrasonic attenuation coefficient and sound velocity In order to accomplishment our purpose, several signal processing methods were used. Attenua4iorl coefficient was estimated by spectral difference method and sound velocity was estimated by P-P method. And we also examined these methods through a series of IN VITRO experi mentis that used tissue-mimicking phantom samples and biological tissue samples. In order to imitate the biological soft tissue two kinds of phantom samples are used, one is agar phantom sample which is composed of agar, graphite, N-propyl alcohol and distilled water, and the other is fat phantom sample which is composed of pure animal fat. And the ultrasound transmission mode and reflection mode experiments are performed on the pig's spleen, kidney and fat. As a result, it is found that the temperature characteristics are uniform in case of phan- tom samples but not in biological tissues because of complicate wave propagation within them. Consequently, the possibility of temperature measurement using ultrasound on biological tissue is confirmed and its results may contribute to the establishment of reference values of internal temperature measurement of biological tissues.

  • Commonly used spices in Korean cooking (red pepper powder, garlic, ginger) were evaluated for anti-obesity properties and effects on triglyceride (TG) and cholesterol in blood and adipose tissues in rats fed a high fat (20%) diet. SD rats were raised for four weeks on either a normal diet (ND, based on the AIN-93M diet), high fat diet (HFD, supplemented with 16% lard oil in the ND), or diets containing 5% red pepper powder (RPP), garlic or ginger. These spices significantly decreased weight gain compared to HFD, but garlic and ginger showed a greater effect on reducing weight gain than RPP. The weights of liver and epididymal and perirenal fat pads in garlic and ginger diet groups were lower than those of the HFD groups (p < 0.05). The garlic and ginger also decreased triglyceride and cholesterol contents in liver and epididymal and perirenal fat pad, reversing the higher levels seen in HFD. RPP, garlic and ginger supplemented diets were effective in lowering serum triglyceride and cholesterol levels (p< 0.05). These results indicated that garlic and ginger more effectively suppressed the effects of HFD on body fat gain and lipid values of adipose tissues and serum than RPP.

  • A feeding trial was conducted with 10 sheep for 12 weeks to examine the effect of soybean oil (SBO) supplementation on long-chain fatty acids composition, especially cis9,trans11-conjugated linoleic acid (c9,t11-CLA) in fat tissues. Sheep were fed either a SBO supplemented diet (5%, DM basis) or a control diet without SBO. Chopped rye grass hay was fed as roughage. Concomitant increases in contents of total cholesterol (T-C) and HDL-cholesterol (HDL-C) in the plasma of sheep were observed from the SBO supplementation. The supplementation of SBO reduced (p<0.05) the proportions of $C_{16:1}$, $C_{17:0}$ and $C_{17:1}$ but increased (p<0.05) the proportions of $C_{18:0}$ and octadecenoic acid (t11-$C_{18:1}$) in the intramuscular fat. The $C_{18:0}$ proportion only in the subcutaneous fat was increased (p<0.05) by the SBO supplementation. The SBO supplementation slightly increased CLA proportion in the intramuscular fat and subcutaneous fat.

  • Objectives: The purpose of this study was to investigate the ameliorative effects of the Epimedium koreanum Nakai (EK) on menopausal obesity in mice. Methods: To induce the menopausal obesity, female C57BL/6J mice were ovariectomized and fed with high fat diet for 12 weeks. 17β-estradiol was injected as a positive control and the extract of EK was orally administered 5 times per week for 6 weeks. Body weight, uterine weight and visceral fat weight were measured. The size of the adipocyte in visceral fat tissues was estimated by Hematoxylin and eosin staining. Fasting glucose level was estimated in serum. Results: Body weight and visceral fat weight were significantly decreased by EK treatment, while the uterine weight/body weight was increased in high fat diet-fed ovariectomized mice. The diameter of adipocyte in the visceral fat tissues was markedly reduced in EK-treated menopausal obese mice. In addition, the fasting blood glucose level was inhibited by oral EK administration. Conclusion: In conclusion, these results showed that EK has ameliorative effects on overweight after menopause. EK could be one of the alternative therapy for treating menopausal obesity.

  • The present studies were designed to compare the effects of both dietary fat levels and P / S ratio on lipid components in plasma and tissues. Changes in plasma HDL-cholesterol, cholesterol and TG, and also in tissue cholesterol and TG were determined in young rats fed diets providing total dietary fat as 10%, 25% or 45% of calories and P / S ratio as 0.2 or 4.0. Plasma cholesterol levels were getting higher as dietary fat levels increased at P / S 0.2. Plasma cholesterol was lower in rats fed dietary fat either 25% or 45 %, each with P / S 4.0. But at 10% no change in plasma cholesterol were observed by P / S 4.0 because of a possible insufficiency of the absolute amount of PUFA. HDL-cholesterol was rather less sensitive to the modification of dietary fat level, but was reduced in rats fed diets of P / S 4.0 at either 25% or 45% fat, even though HDL-cholesterol were increased in the group of 10% with P / S 0.2. Total cholesterol per g- liver were significantly increased as dietary fat levels increased. Liver cholesterol levels were higher in rats fed diets of P / S 4.0 at higher fat levels (25% or 45%) which possibly suggested that a reduction of plasma cholesterol by high PUFA diet was not at least from a decreased synthesis of cholesterol in liver. However, in muscle no significant differences were found by feeding high P / S ratio at each levels of fat. At 10% fat level, compared to 25% or 45%, cholesterol level was lower in g-liver but higher in g- muscle. Plasma TG was decreased as more dietary fat were supplied at P / S ratio, but no consistant response obtained at low P / S ratio. TG per g-liver were reduced by feeding P / S 4.0 diet at 10% or 45% fat level but no differences were found in muscle. P / S 4.0 diet was more efficient in lowering plasma cholesterol TG and HDL-cholesterolt levels only if fat level was more than 25% of the total calories And young rats were more resistant to dietary fat modification.

  • The objective of this study was to investigate the correlation between cattle breeds and deposit of adipose tissues in different positions and the gene expressions of peroxisome proliferator-activated receptor gamma ($PPAR{\gamma}$), fatty acid synthase (FASN), and Acyl-CoA dehydrogenase (ACADM), which are associated with lipid metabolism and are valuable for understanding the physiology in fat depot and meat quality. Yanbian yellow cattle and Yan yellow cattle reared under the same conditions display different fat proportions in the carcass. To understand this difference, the expression of $PPAR{\gamma}$, FASN, and ACADM in different adipose tissues and longissimus dorsi muscle (LD) in these two breeds were analyzed using the Real-time quantitative polymerase chain reaction method (qRT-PCR). The result showed that $PPAR{\gamma}$ gene expression was significantly higher in adipose tissue than in LD in both breeds. $PPAR{\gamma}$ expression was also higher in abdominal fat, in perirenal fat than in the subcutaneous fat (p<0.05) in Yanbian yellow cattle, and was significantly higher in subcutaneous fat in Yan yellow cattle than that in Yanbian yellow cattle. On the other hand, FASN mRNA expression levels in subcutaneous fat and abdominal fat in Yan yellow cattle were significantly higher than that in Yanbian yellow cattle. Interestingly, ACADM gene shows greater fold changes in LD than in adipose tissues in Yan yellow cattle. Furthermore, the expressions of these three genes in lung, colon, kidney, liver and heart of Yanbian yellow cattle and Yan yellow cattle were also investigated. The results showed that the highest expression levels of $PPAR{\gamma}$ and FASN genes were detected in the lung in both breeds. The expression of ACADM gene in kidney and liver were higher than that in other organs in Yanbian yellow cattle, the comparison was not statistically significant in Yan yellow cattle.
