The aim of this study was to examine the effects of perilla oil as well as several vegetable oils, including flaxseed oil, canola oil, and rice bran oil on plasma levels of cardioprotective (n-3) polyunsaturated fatty acids in mice by feeding each vegetable oil for a period of eight weeks. Concentrations of docosapentaenoic acid (DHA) and eicosapentaenoic acid (EPA), fish-based (n-3) polyunsaturated fatty acids, showed an increase in the plasma of mice fed perilla and flaxseed oils compared to those of mice in the control group (P < 0.05), whereas rice bran and canola oils did not alter plasma DPA and EPA concentrations. Arachidonic acid concentration was increased by feeding rice bran oil (P < 0.05), but not canola, flaxseed, or perilla oil. In addition, oleic acid, linoleic acid, and docosahexaenoic acid concentrations were altered by feeding dietary rice bran, canola, perilla, and flaxseed oils. Findings of this study showed that perilla oil, similar to flaxseed oil, is cardioprotective and could be used as an alternative to fish oil or even flaxseed oil in animal models.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is increasingly recognized as a major cause of liver-related morbidity and mortality. The underlying mechanisms of disease progression remain poorly understood, and primary therapy of NAFLD is not yet established. We investigated the effects of dietary oleate on the development and progression of NAFLD in a methionine- and choline-deficient (MCD) diet-fed animal model. METHODS: A total of 30 C57BL/6J mice were randomly divided into three groups (n=10 in each group) and fed various experimental diets for four weeks: chow, MCD diet, or OMCD (MCD diet with oleate, 0.5 mg/g/day). Liver samples were examined for steatohepatitis and fibrosis parameters and associated genes. RESULTS: Additional dietary oleate dramatically reduced MCD diet-induced hepatic steatosis. Hepatic carbohydrate responsive element-binding protein was overexpressed in MCD diet-fed mice, and dietary oleate prevented this overexpression (P<0.001). Dietary oleate partially prevented MCD diet-induced serum level increases in aspartate aminotransferase and alanine aminotransferase (P<0.001, respectively). The mRNA expressions of hepatic monocyte chemoattractant protein 1, tumor necrosis factor-alpha and matrix metalloproteinase-9 were increased in MCD diet-fed mice, and this overexpression of inflammatory molecules was prevented by dietary oleate (P<0.001). Hepatic pericellular fibrosis was observed in MCD diet-fed mice, and dietary oleate prevented this fibrosis. Altogether, dietary oleate prevented MCD diet-induced hepatic steatosis, inflammation and fibrosis. CONCLUSION: Dietary oleate has beneficial effects in every step of NAFLD development and progression and could be a nutritional option for NAFLD prevention and treatment.

In this study, we examined the hepatic anti-steatosis activity of carnosic acid (CA), a phenolic compound of rosemary (Rosmarinus officinalis) leaves, as well as its possible mechanism of action, in a high-fat diet (HFD)-fed mice model. Mice were fed a HFD, or a HFD supplemented with 0.01% (w/w) CA or 0.02% (w/w) CA, for a period of 12 weeks, after which changes in body weight, blood lipid profiles, and fatty acid mechanism markers were evaluated. The 0.02% (w/w) CA diet resulted in a marked decline in steatosis grade, as well as in homeostasis model assessment of insulin resistance (HOMA-IR) index values, intraperitoneal glucose tolerance test (IGTT) results, body weight gain, liver weight, and blood lipid levels (P < 0.05). The expression level of hepatic lipogenic genes, such as sterol regulating element binding protein-1c (SREBP-1c), liver-fatty acid binding protein (L-FABP), stearoyl-CoA desaturase 1 (SCD1), and fatty acid synthase (FAS), was significantly lower in mice fed 0.01% (w/w) CA and 0.02% (w/w) CA diets than that in the HFD group; on the other hand, the expression level of beta-oxidation-related genes, such as peroxisome proliferator-activated receptor alpha (PPAR-alpha), carnitine palmitoyltransferase 1 (CPT-1), and acyl-CoA oxidase (ACO), was higher in mice fed a 0.02% (w/w) CA diet, than that in the HFD group (P < 0.05). In addition, the hepatic content of palmitic acid (C16:0), palmitoleic acid (C16:1), and oleic acid (C18:1) was significantly lower in mice fed the 0.02% (w/w) CA diet than that in the HFD group (P < 0.05). These results suggest that orally administered CA suppressed HFD-induced hepatic steatosis and fatty liver-related metabolic disorders through decrease of de novo lipogenesis and fatty acid elongation and increase of fatty acid beta-oxidation in mice.

6.Comparison of Nutrient Intakes Regarding Stages of Change in Dietary Fiber Increasing for College Students in Kyunggi-Do.
Korean Journal of Community Nutrition 2005;10(5):592-602
This study was conducted to compare nutrient intakes regarding stages of change in dietary fiber increasing behavior. Subjects were consisted of healthy 383 college students (250 females and 133 males) in Kyunggi-Do. Stages of change classified by an algorithim based on 6 items were designed each subjects into one of the 5 stages: precontemplation (PC), contemplation (CO), preparation (PR), action (AC), maintenance (MA). Nutrient intakes were assessed by 24-hr recall method. Regarding the 5 stages of changes, PR stage comprised the largest group (39.4%), followed by AC (33.7%), MA (14.6%), PC (7.6%), CO (4.7%). Female were more belong to either AC or MA. The higher stage of change in dietary fiber increasing behavior, the higher self-efficacy. In all male and female, there were no differences in energy, protein, monounsaturated fatty acids, polyunsaturated fatty acids and cholesterol intakes across the 5 stages. But, fiber, potassuim (K), vitamin A and vitamin C intakes of AC or MA were higer than those of PC, CO and PR. Energy% from fat of PR (25.4 - 26.5%) was higher than 20%, and those of AC and MA was lower than the other groups. Dietary P/S and omega6/omega3 ratios of AC and MA were similar to the recommended ratio. Female of PR had the most total saturated fat and palmitic acid and those of MA had the least. Male of PR had the least alpha-LNA (omega3) and total omega3 fatty acids and those of MA had the most. In male and female in AC or MA, fiber and K intakes from breakfast, dinner and snack and vitamin C intakes from all meals were higher than those of the other stages. These results of our study confirm differences in stages of change in fiber intake in terms of nutritional status. To have lower energy% from fat, higher intakes of K, fiber and vitamins, desirable ratio of dietary fatty acids, it needs consistent nutritional education leading to the AC or MA of fiber increasing behavior.

BACKGROUND: Numerous studies have suggested that polyunsaturated fatty acids (PUFAs)-supplemented diets may decrease cardiovascular morbidity and mortality. Especially, omega-3 PUFAs may exert beneficial effects to the treatment and prevention of dyslipidemias, arrhythmias, atherosclerosis, and hypertension. METHODS: This study investigated plasma lipid profiles including total cholesterol, triglycerides (TG), LDL, HDL, and antioxidant status indicative of vitamin A, vitamin E, malondialdehyde (MDA) and distribution of plasma long-chain fatty acids (C12-C24) in 28 normal subjects and 24 hypertensive patients. Also, the correlation among PUFAs, levels of antioxidant status, and lipid profiles of the subjects were estimated. RESULTS: The distribution of omega-3 PUFAs, saturated fatty acids, and monounsaturated fatty acids showed significant differences (P<0.05), but that of omega-6 PUFAs did not exhibit significant differences. The omega-6/omega-3 ratio exhibited 36.96 in normal group and 14.29 in the hypertensive patient group. The levels of vitamin A, vitamin E, and MDA were increased significantly in the hypertensive patient group. CONCLUSION: PUFA levels were estimated in the hypertensive patients and normal group. The results suggest that dietary intake of proper omega-6/omega-3 ratio is needed for prevention and treatment of hypertension.

Forest musk deer is one of the large-scale farming musk deer animals with the largest population at the same time. The male musk deer can secrete valuable medicines, which has high medicinal and economic value. Due to the loss of habitat and indiscriminate hunting, the numbers of wild population specie and the distribution have been drastically reduced. Therefore, in-depth understanding of the molecular genetics progress of forest musk deer will pave a way for musk deer protection and breeding. In this review, the progress associated with the molecular marker, genetic classification, artificial breeding, musk secretion and disease in past decades were reviewed, in order to provide a theoretical basis for subsequent molecular genetic researches in forest musk deer.

Forest musk deer (Moschus berezovskii), a rare wild medicinal animal, is listed under the category of the state key protected wildlife list of China. Musk, secreted by the musk glands, is with high economic and medicinal value and used as precious traditional medicine in China. In order to meet the needs of musk in Chinese traditional medicine, forest musk deer farming was conducted in 1950s, but the research progress on musk secretion mechanism was slow. Therefore, by reviewing the histological and anatomical structure of forest musk deer musk gland, the relationship between sex hormones and the musk secretion process, and the molecular mechanism of the musk secretion, the existing problems in investigating the musk secretion mechanism were analyzed and the development trends in this field were also discussed, in order to provide a reference for further studies on the musk secretion mechanism and improve musk production of forest musk deer.
