  • This research was planned and executed to evaluate how the composition of Yak-sun(oriental diet therapy) can effect health conditions of people who are suffering from diet-related diseases like obesity and hyperlipidemia by taking Yak-sun in a form of nutritional supplement with our daily meals. We produced Jangswucha with Koekac, Sansa, Heshouwu, Wulong and evaluated how this tea effects on serum lipids and oxidative stress by clinical practices. Also we examined physical characteristics of Jangswucha. Brix, pH and titratable acidity of Jangswucha were 1.4, 5.50 and 0.05%. With this observation, we found out that this tea has significant effect on increase of HDL-cholesterol, decrease of LDL-cholesterol concentration in serum. Also this tea significant effect on decrease oxidative stress and homocystein content. We think that scientific and objective evaluation was done on the components of Yak-sun tea prescription. We concluded that we could apply the components not only in a form of tea, but also in other forms of various food. The information we received from this conclusion will be a basic information on how we can apply oriental medicinal resources into other food and will also be a steppingstone for medicinal herbs to step foot in the field of functional food research, which already draws sizable attention world-wide.

  • Changes in total lipid content, total cholesterol content and fatty acid composition of preterm milk were investigated during early lactation. Milk samples were collected from Korean mothers of 16 premature(34 to 36 weeks gestation age) infants on day 2 to 5(colostrum) and at 6 weeks(mature) postpartum. We estimated the lipid nutrition of preterm milk by comparing with the lipids of term milk. The total lipid content of preterm colostrum was significantly lower than the lipid content of preterm mature milk(p<0.001). Lipid content, determined gravimetrically in colostrum and matured milk, was 1.50g/이 and 3.2g/dl, respectively. Also the total cholesterol content(mg/dl) in preterm milk tends to increase from 14.16mg/dl to 15.20mg/dl, while the total cholesterol(mg/g lipid) concentration higher significantly in colostrum(12.36mg/g) than in mature(5.73mg/g)(p<0.001). The total unsaturated fatty acid contents in preterm milk were higher in colostrum than in mature milk and the total saturated fatty acids were higher in mature milk. The average DHA contents of colostrum and matured milk was 0.64%, 0.53% and the P/M/S ratio of preterm milk were 0.63 : 1.05 : 1.00, 0.47 : 0.79 : 1.00, respectively. Also, $\omega$6/$\omega$3 ratio of preterm milk were 2.35 in colostrum and 5.81 in mature. Therefore, colostrum in preterm milk contained higher amounts of $\omega$3 PUFA than mature milk. The levels of total lipid in preterm milk were higher than term milk. Also, preterm milk is richer in cholesterol, and long chain polyunsaturated fatty acid than term. It appears that the milk secreted by mothers who delivered prematurely differs from milk in several important respect. These components may serve as precursors for membrane, myelin development in the preterm infants. Therefore, it would be necessary to study further into the machanism of how the gestation age might affect to the lipid composition in human milk. These data may provide a basis for better construction of infant formaulas to provide more adequately for the lipid requirements of the Korean premature infant.

  • We investigated the effect of tea fungus/kombucha(TF) beverage on serum and liver lipid metabolism in growing male rats. The rats(Sprague-Dawley) were divided into five groups; control(TF free water), 20 or 40% TF groups(20 or 40% TF in water) and 20 or 40% TFS groups(20 or 40% TF autoclaved in water) according to the level of TF supplementation. The rats were fed ad libitum each of the experimental beverage for 7 weeks. The body weight gain of all the TF and TFS groups were similar to that of the control group. The total lipid and triglyceride concentrations of serum in the 40% TF group were increased more than those in the control group, but those in the 20% TF and 20% TFS groups were similar to that of the control group. The total cholesterol, HDL-cholesterol concentrations, HDL-cholesterol / total cholesterol ratio and atherogenic index of serum in all the TF and TFS groups were similar to those of the control group. The LDL-cholesterol concentration of serum was significantly lower in the 20% TF group than that in the control group. The LDL-cholesterol concentration of serum was significantly lower in the 20% TF group than that in the control group, but those of the 40% TF, 20% TFS and 40% TFS groups were similar to that of the control group. The liver weights of all the TF and TFS groups were heavier than that of the control group. The concentrations of hepatic triglyceride in the 20% TF and 20% TFS groups were significantly decreased, compared with that in the control group. The concentrations of hepatic total cholesterol in all the TF and TFS groups were significantly more decreased than that in the control group. These results indicated that the liver weights of tea fungus/kombucha beverage feeding rats were increased, also the serum triglyceride and total cholesterol concentrations of 40% TF feeding rats were increased. but the serum LDL-cholesterol, hepatic triglyceride and cholesterol levels of 20% TF feeding rats were decreased.

  • This study was performed to investigate the possible effects of some plants protecting intact rat liver damaged by $CCl_4$. The extract of mugwort (Artemsiae capillaris), soybean sprout and pine leaf (Pinus strobus) inhibited markedly the in vitro activities of rat liver fatty acid synthase, whereas those of shiitake (Lentinus ododes), Houttuynia cortata, Acanthopanacis cortex and buckwheat leaves had less effects. Treatment with the water extract of pine leaf and soybean sprout caused a marked decrease in the $CCl_4$-induced toxicity in rat liver, judged from their effects on the levels of glutamic oxaloacetic transaminase (GOT) and glutamate pyruvic transaminase(GPT) in the serum. The extract of mugwort and soybean sprout reduced markedly the content of liver microsomal peroxides induced by $CCl_4$ treatment and serum TBA values, respectively. The extract of soybean sprout decreased efficiently the content of liver triglyceride elevated by $CCl_4$ treatment. Nevertheless, the extracts did not exert the supression of hepaticmegaly induced by $CCl_4$. The results suggest that soybean sprout and pine leaf may be potential sources improved the biochemical parameters like as peroxidation value or serum GOT and GPT, although these extracts had minimal effects in the increase of liver size induced by carbon tetrachloride.

  • Objective: Stress-induced cytotoxicity caused by xenobiotics and endogenous metabolites induces the production of reactive oxygen species and often results in damage to cellular components such as DNA, proteins, and lipids. The cytochrome P450 (CYP) family of enzymes are most abundant in hepatocytes, where they play key roles in regulating cellular stress responses. We aimed to determine the effects of the antioxidant compound, methylsulfonylmethane (MSM), on oxidative stress response, and study the cytochrome P450 family 3 subfamily A (CYP3A) gene expression in fetal horse hepatocytes. Methods: The expression of hepatocyte markers and CYP3A family genes (CYP3A89, CYP3A93, CYP3A94, CYP3A95, CYP3A96, and CYP3A97) were assessed in different organ tissues of the horse and fetal horse liver-derived cells (FHLCs) using quantitative reverse transcription polymerase chain reaction. To elucidate the antioxidant effects of MSM on FHLCs, cell viability, levels of oxidative markers, and gene expression of CYP3A were investigated in H2O2-induced oxidative stress in the presence and absence of MSM. Results: FHLCs exhibited features of liver cells and simultaneously maintained the typical genetic characteristics of normal liver tissue; however, the expression profiles of some liver markers and CYP3A genes, except that of CYP3A93, were different. The expression of CYP3A93 specifically increased after the addition of H2O2 to the culture medium. MSM treatment reduced oxidative stress as well as the expression of CYP3A93 and heme oxygenase 1, an oxidative marker in FHLCs. Conclusion: MSM could reduce oxidative stress and hepatotoxicity in FHLCs by altering CYP3A93 expression and related signaling pathways.

  • Objectives : This study was designed to investigate the effects of an aqueous extract from Buddleja officinalis Maxim (ABO) on vascular dysfunction in low-density lipoprotein receptor deficient (LDLr KO) mice. Methods : Present study showed that LDLr KO mice were fed a high fat diet consisting of 60 kcal% fat, with or without 200 mg/day/kg ABO of diet, for 14 weeks. Results : High fat diet-LDLr KO mice were treated with ABO were completely normalized by lowering glucose. ABO reduced intima/media thickness in a high fat diet-LDLr KO mice without affecting plasma cholesterol and triglyceride levels. ABO caused endothelium-dependent relaxation in the acetylcholine-precontracted aorta of high fat diet-LDLr KO mice. ABO increased eNOS expression, while decreased cell adhesion molecules expression in high fat diet-LDLr KO mice. Conclusions : In conclusion, chronic treatment with ABO improved hyperglycemia and endothelium-dependent vascular relaxation as well as exhibited anti-inflammatory effect in diabetic atherosclerotic mouse model, independent of effects on plasma lipids.

  • Oxidative stress is a critical factor affecting the quality and viability of sperm during boar semen storage. Oxidative stress is also a significant concern during the process of freezing semen. The process of semen storage involves exposing the sperm to various stressors, including temperature changes, cryoprotectants, and extended periods of incubation. In addition, oxidative stress can lead to the production of reactive oxygen species (ROS) within the sperm, resulting in oxidative damage to cellular components, such as lipids, proteins, and DNA. Striking a balance between ROS production and the antioxidant defense system is crucial for maintaining sperm viability and functionality during semen storage. Moreover, the prolonged storage of boar semen leads to an increase in ROS levels, which can impair sperm motility, membrane integrity, and DNA integrity. ROS-induced lipid peroxidation affects the fluidity and stability of sperm membranes, leading to decreased sperm motility. Moreover, oxidative damage to the DNA can result in DNA fragmentation, compromising the genetic integrity of the sperm. In conclusion, oxidative stress is a significant challenge in maintaining sperm quality during boar semen storage. Understanding the mechanisms underlying oxidative stress and their impacts on sperm function is crucial for developing effective strategies to minimize oxidative damage and improve sperm storage outcomes.

  • BACKGROUND/OBJECTIVES: Activating brown adipose tissue (BAT) and browning of white adipose tissue (WAT) can protect against obesity and obesity-related metabolic conditions. Cryptotanshinone (CT) regulates lipid metabolism and significantly ameliorates insulin resistance. Adenosine-5'-monophosphate (AMP)-activated protein kinase (AMPK), a receptor for cellular energy metabolism, is believed to regulate brown fat activity in humans. MATERIALS/METHODS: The in vivo study included high-fat-fed obese mice administered orally 200/400 mg/kg/d CT. They were evaluated through weight measurement, the intraperitoneal glucose tolerance test (IPGTT), intraperitoneal insulin tolerance test (IPITT), cold stimulation test, serum lipid (total cholesterol, triglycerides, and low-density lipoprotein) measurement, hematoxylin and eosin staining, and immunohistochemistry. Furthermore, the in vitro study investigated primary adipose mesenchymal stem cells (MSCs) with incubation of CT and AMPK agonists (acadesine)/inhibitor (Compound C). Cells were evaluated using Oil Red O staining, Alizarin red staining, flow cytometry, and immunofluorescence staining to identify and observe the osteogenic versus adipogenic differentiation. Quantitative real-time polymerase chain reaction and the Western blot were used to observe related gene expression. RESULTS: In the diet-induced obesity mouse model mice CT suppressed body weight, food intake, glucose levels in the IPGTT and IPTT, serum lipids, the volume of adipose tissue, and increased thermogenesis, uncoupling protein 1, and the AMPK pathway expression. In the in vitro study, CT prevented the formation of lipid droplets from MSCs while activating brown genes and the AMPK pathway. AMPK activator enhanced CT's effects, while the AMPK inhibitor reversed the effects of CT. CONCLUSION: CT promotes adipose tissue browning to increase body thermogenesis and reduce obesity by activating the AMPK pathway. This study provides an experimental foundation for the use of CT in obesity treatment.
