Objective: This study was undertaken to investigate how magnolia bark extract affects ob/ob mouse in terms of metabolic inflammation and insulin resistance. Methods: Leptin-deficient ob/ob mice were divided into 2 groups (n=5): a normal saline treatment (=control) and magnolia bark treatment. Wild type mice were the lean group (n=5). After 5 weeks, we measured fasting blood sugar (FBS) and conducted oral glucose tolerance tests (OGTTs) in each group. After 6 weeks, we measured body weight, epididymal fat pad weight, liver weight, serum glucose, serum insulin, and gene expression of tumor necrosis factor-${\alpha}$, interferon-${\gamma}$, and interleukin-6. We characterized the phenotype of adipose tissue macrophages (ATMs) and analyzed fractions of the phenotype in each group by flow cytometry. Results: In the magnolia bark group, fasting blood sugar, oral glucose tolerance levels, and insulin resistance (HOMA-IR) were significantly decreased. The population and proportion of ATMs among leukocytes in adipose tissue were significantly decreased in the magnolia bark group. The population and proportion of M1 type ATMs among ATMs were significantly decreased in the magnolia bark group. Gene expression of tumor necrosis factor-${\alpha}$ was significantly decreased in the magnolia bark group. Conclusions: These results support a positive effect of magnolia bark on metabolic diseases such as insulin resistance and metabolic inflammation in leptin-deficient ob/ob mice.

Objectives: This study was conducted to investigate the effects of Morindae officinalis Radix (巴戟) on the spermatogenesis and antioxidant activities in the Sprague Dawley (SD) rat. Materials and Methods: We choose the 2-month-old SD rats, and administered the extract powder of Morindae officinalis Radix once in a day for 28 days. The control rats were administered normal water in the same way and duration. We observed changes of body weight, surgically isolated testis, epididymis, vascular gland and prostate gland before and after administration of Morindae officinalis Radix extracts in SD Rats. Also we compared the testicular tissue, especially seminiferous tubules between the control and treated groups by histochemical methods. In addition, we examined the total, normal, morphologic and motile sperm in the cauda epididymis, and the activity of catalase and peroxidase in the isolated testis tissue. Results: There was no significant difference between control and treatment groups in the body weight, testis, vascular and prostate gland, but the weight of epididymis showed significant difference in the control group. The concentration of total sperm, the motility and normality of spermatozoa was significantly different when compared with the control group, respectively. In the histological examination of testicular tissues, the tendency of increasement of angiogenesis between seminiferous tubules was observed. And the concentration of spermatogonia, primary and secondary spermatocyte and sperm were higher than that of control testicular tissues. Finally, the activity of catalase and peroxidase related inhibitory molecules of oxidation were slightly increased in the treatment group than those of control group. Conclusions: This study shows that Morindae officinalis Radix has the beneficial effect on the concentration, morphology and motility of sperm, the important factor in male fertility. We can suggest that Morindae officinalis Radix has an effect on the spermatogenesis in the SD rat.

Objective : This study was performed to investigate the effect of Sunhwangigagambang(SHG) on hyperlipidemia in SD rats induced by high cholesterol diet. Method : After treatment with SHG, cytotoxicity, body weight, liver weight, AST, ALT, ALP, total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, glucose, albumin, total protein in serum, malondialdehyde, and gene expression for ACAT and HMG-CoA reductase in hepatic tissue were analyzed. Result : 1. SHG didn't show any cytotoxicity in both human fibroblast cell line and SD rats. 2. SHG significantly inhibited the increase of liver weight by high cholesterol diet compared to the control group. 3. SHG significantly ameliorated the increase of total cholesterol, LDL-cholesterol, and triglyceride and reduction of HDL-cholesterol compared to the control group. 4. SHG significantly reduced glucose level in serum compared to the control group. 5. SHG significantly reduced malondialdehyde in hepatic tissue compared to the control group. 6. SHG significantly down-regulated gene expression of ACAT and HMG-CoA reductase compared to the control group. Conclusion : These results suggest that SHG might be effective in treatment and prevention of hyperlipidemia.
BACKGROUND/OBJECTIVES: Different fatty acids exert different health benefits. This study investigated the potential protective effects of perilla, olive, and safflower oils on high-fat diet-induced obesity and colon inflammation. MATERIALS/METHODS: Five-week old, C57BL/6J mice were assigned to 5 groups: low-fat diet (LFD), high-fat diet (HFD) and high-fat diet supplemented with-perilla oil (HPO), olive oil (HOO), and safflower oil (HSO). After 16 weeks of the experimental period, the mice were sacrificed, and blood and tissues were collected. The serum was analyzed for obesity- and inflammation-related biomarkers. Gene expression of the biomarkers in the liver, adipose tissue, and colon tissue was analyzed. Micro-computed tomography (CT) analysis was performed one week before sacrifice. RESULTS: Treatment with all the three oils significantly improved obesity-induced increases in body weight, liver weight, and epididymal fat weight as well as serum triglyceride and leptin levels. Treatment with perilla oil (PO) and safflower oil (SO) increased adiponectin levels. The micro-CT analysis revealed that PO and SO reduced abdominal fat volume considerably. The mRNA expression of lipogenic genes was reduced in all the three oilsupplemented groups and PO upregulated lipid oxidation in the liver. Supplementation of oils improved macroscopic score, increased colon length, and decreased serum endotoxin and proinflammatory cytokine levels in the colon. The abundance of Bifidobacteria was increased and that of Enterobacteriaceae was reduced in the PO-supplemented group. All three oils reduced proinflammatory cytokine levels, as indicated by the mRNA expression. In addition, PO increased the expression of tight junction proteins. CONCLUSIONS: Taken together, our data indicate that the three oils exert similar anti-obesity effects. Interestingly, compared with olive oil and SO, PO provides better protection against high-fat diet-induced colon inflammation, suggesting that PO consumption helps manage inflammation-related diseases and provides omega-3 fatty acids needed by the body.
As obesity is known to be related to hyperlipidemia, insulin and leptin resistance, and other chronic diseases, much recent research has focused on functional food materials and their anti-obesity activity. This study was performed to study the effects of Artemisia Iwayomogi oligosaccharide AIPI on the anti-obesity function in normal rats and diet-induced obese (DIO) rats. F344 male rats were divided into four groups: Normal-control (CONT), normal-AIPI, DIO-CONT and DIO-AIPI. The groups were provided with water (in the CONT groups) or another drink for 4 weeks. The final body weights of rats in the DIO-AIPI group were lower than those in the CONT group. Abdominal adipose tissue weight per kg of body weight in the DIO-AIPI group was significantly lower than that in the DIO-CONT group. Also, the final levels of serum-triglyceride, serum-total cholesterol and serum-low density lipoprotein cholesterol in the DIO-AIPI group were lower than those in the DIO-CONT group. Moreover, the serum-high density lipoprotein cholesterol level in the normal-AIPI group was significantly higher than that in the normal-CONT group. Finally, the serum-leptin concentration was significantly lower in the DIO-AIPI group. Total lipid, triglyceride, and total cholesterol contents in the feces of the DIO-AIPI group were as high as 142%, 199%, and 165% of the respective values of the DIO-CONT GROUP. These results indicate that orally administered Artemisia Iwayomogi oligosaccharide not only has hypotriglycemic and hypocholesterolemic effects, but also has the effect of reducing the body weight and the abdominal adipose tissue weights obese rats. Therefore, we expect that Artemisia Iwayomogi oligosaccharide AIPI may have an anti-obesity function in F344 diet-induced obese rats. (Korean J Nutrition 36(5): 437∼445, 2003)

The purpose of this study was to examine the effects of Angelica gigas Nakai on ulcerative colitis. Mice were divided into 5 groups: Control group, DSS group, 5-ASA group, 50mg/kg Angelica gigas Nakai group, 100mg/kg Angelica gigas Nakai group. Four groups, excluding the control group, were fed a 5% solution of dextran sulfate sodium(DSS) in water for 7days to induce ulcerative colitis. Each water extract was administrated orally for 7 days in 5-ASA group, 50mg/kg Angelica gigas Nakai group and 100mg/kg Angelica gigas Nakai group. 5 groups were evaluated by weight, length of intestine, weight of spleen, disease activity index(DAI), amount of cytokine IL-6 production, thickness of bowel wall and degree of inflammatory cell infiltration and intestinal tissue damage. Comparing to DSS group, 100 mg/kg Angelica gigas Nakai group showed significant suppressive effect of weight loss until 4th day of experiment while 50 mg/kg Angelica gigas Nakai group showed no significant effect of suppression. Decrease of intestinal length, enlargement of spleen, intestinal tissue damage and thickening of bowel wall were significantly suppressed in both 50 mg/kg and 100mg/kg Angelica gigas Nakai group. Also disease activity and cytokine IL-6 production were inhibited significantly. Based on this result, Angelica gigas Nakai seemed to have anti-inflammatory effect and also seemed to suppress histological changes and aggravation of ulcerative colitis.
The effects of dried leaf powders and ethanol extract of persimmon, green tea and pine needle on lipid metabolism, lipid peroxidation and antioxidative activity were investigated in rats. Forty-nine male Spargue-Dawley rats weighing 107.8$\pm$1.8g were blocked into seven groups according to body weight. Rats were raised for four weeks with diets containing either 5%(w/w) dried leaf powders of one of three different Korea traditional teas, persimmon(Diospyros kaki Thunb), green tea(Camellia Sinensis O.Ktzc)or pine needle(pinus Koreansis Sieb. Et Zucc), or ethanol from equal amounts of each dried tea powder. Food intake, weight gain, food efficiency ratio, and weights of liver, kidney and epididymal fat were significantly higher in the green-tea-powder group, and significantly lower in the pine-needle-powder and pine-needle-extract groups. Persimmon-leaf powder was found to decrease plasma total lipid, triglyceride and cholesterol concentration by increasing fecal total lipid triglyceride and cholesterol excretions. Liver cholesterol concentration was significantly lower in the green-tea and pine-needle-extract groups. Red-blood-cell superoxide dismutase(SOD) and glutathione peroxidase(GSH-px) activities were significantly increased in rats fed green-tea extract. Liver SOD activity was increased in rats fed pine-needle powder or extract, and liver GSH-px activity was increased in rats fed greentea powder. Plasma and liver thiobarbituric acid reactive substance(TBARS) concentration were both decreased in rats fed dried leaf posers or extracts of persimmon or green tea. It is believed that high vitamin E levels in persimmon leaf, and high flavonoid, beta-carotene and vitamin C levels in green tea effectively inhibited lipid peroxidation. In conclusion, persimmon and green tea leaves were effective in lowering lipid levels and inhibiting lipid peroxidation in animal tissue, while pine needles were effective and lowering body weight gain. From these results, persimmon and green tea leaves can be recommended in the treatment and prevention of chronic discorders such as cardiovascular disease, cancer and aging. As ethanol extracts from these teas were also effecitive in lowering tissue lipid levels and inhibiting lipid peroxidation, we recommend the use of discarded tea grounds for this.
Objective : The aim of this study is to investigate the inhibitory effect of Injinchunggantang on hepatic sclerosis induced by $CCl_4$. Methods : Weight, liver function test and complete blood cell count, gross findings, and findings on liver tissue of the past(Hematoxylin & Eosin stain, Masson-Trichrome stain) were studied. Results : When it comes to the change of rats' body weight, The $CCl_{4^+}$Injinchunggantang group lost far less weight than The $CCl_{4^-}$only group. In the liver function test, which is focused on various areas such as total cholesterol, alkaline phosphotase, albumin, aspartate transaminase, alanine transaminase, The $CCl_{4^+}$Injinchunggantang group was much more closer to normal limit than the $CCl_4$ only group. In the complete blood cell count, including white blood cell, red blood cell, hemoglobin, hematocrite, platelet, The $CCl_{4^+}$Injinchunggantang group significantly closer to normal limit than $CCl_{4^-}$only group. In the gross findings of hepatic fibrosis models, Injinchunggantang showed inhibitory effect on hepatic fibrosis in the order. In the past findings of hepatic fibrosis models in Hematoxylin & Eosin, Masson-Trichrome staining, the liver in $CCl_{4^-}$only group showed atrophy and necrotic change with white nodules, whereas that of $CCl_{4^+}$Injinchunggantang group showed lesser significant change with the well_preserved tone of the tissue. In the extent of the inhibition of the hepatic fibrosis, the Injinchunggantang group showed statistically significant inhibitory effect(p<0.05) in the sclerosis model. Conclusions : These results show that Injinchunggantang have inhibitory effect on hepatic sclerosis induced by $CCl_4$ and further ultimately prevent liver cirrhosis. To obtain more credible results in this experiment, the invention of a new experimental model more similar to human hepatic sclerosis is still needed.

Background Patients having unilateral breast reconstruction often require a second stage procedure on the contralateral breast to improve symmetry. In order to provide immediate symmetry and minimize the frequency and extent of secondary procedures, we began performing simultaneous contralateral balancing operations at the time of initial reconstruction. This study examines the indications, safety, and efficacy of this approach. Methods One-hundred and two consecutive breast reconstructions with simultaneous contralateral balancing procedures were identified. Data included patient age, body mass index (BMI), type of reconstruction and balancing procedure, specimen weight, transfusion requirement, complications and additional surgery under anesthesia. Unpaired t-tests were used to compare BMI, specimen weight and need for non-autologous transfusion. Results Average patient age was 48 years. The majority had autologous tissue-only reconstructions (94%) and the rest prosthesis-based reconstructions (6%). Balancing procedures included reduction mammoplasty (50%), mastopexy (49%), and augmentation mammoplasty (1%). Average BMI was 27 and average reduction specimen was 340 grams. Non-autologous blood transfusion rate was 9%. There was no relationship between BMI or reduction specimen weight and need for transfusion. We performed secondary surgery in 24% of the autologous group and 100% of the prosthesis group. Revision rate for symmetry was 13% in the autologous group and 17% in the prosthesis group. Conclusions Performing balancing at the time of breast reconstruction is safe and most effective in autologous reconstructions, where 87% did not require a second operation for symmetry.
Objectives : This research was performed to investigate the effect of acupuncture using invasive low level laser therapy (LLLT) at Yolgyol (LU7) + Yogu (LR5) on weight gain, food intake, food efficiency, lipid metabolism, atherogenic index, HTR (HDL-cholesterol to total cholesterol ratio) and morphological change of hepatic tissue in hyperlipdemia rats. Methods : Experimental groups were divided into high fat diet group (Control group), high fat diet and acupuncture therapy group at LU7 + LR5 (AT group), high fat diet and acupuncture group using 10 mW LLLT at LU7 +LR5 (LA10 group), high fat diet and acupuncture group using 20 mW LLLT at LU7+LR5(LA20 group), high fat diet and acupuncture group using 60 mW LLLT at LU7 + LR5 (LA60 group), once per 3 days during 9 weeks. Results : Body weight was decreased significantly in AT and LA20 groups compared with Control group. Food intake was increased significantly in LA60 group compared with Control group. Food efficiency was decreased significantly in LA10, LA20 and LA60 groups compared with control group. In the lipid metabolism, total cholesterol was decreased significantly in AT, LA10, LA20 and LA60 groups, triglyceride was decreased significantly in LA10, LA20 and LA60 groups, TG/HDL-cholesterol ratio was decreased significantly in LA 60 group compared with control group. In the morphological change, hepatic tissue were not showed balloning degeneration and irregular arrangement of hepatic cell in LA10 and LA20 groups with control group. Conclusions : Acupuncture using LLLT at LU7+LR5 can manage hyperlipemia by controlling body weight, food intake, food efficiency ratio and lipid metabolism.
