The current study was designed to evaluate the effect of sequential low and high dietary linseed oil (LO; as omega-3 enriched fatty acid; FA) before and post insemination, respectively, on different plasma variables of ewes. Fat-tailed Qezel ewes were assigned randomly to be fed a diet enriched with 3% LO (n = 30) or the saturated FA (SFA; n = 30) three weeks before insemination (Day 0). The lipogenic diet supplemented with 6% LO or SFA was fed after insemination until Day +21. The control ewes were fed an isocaloric and isonitrogenous diet with no additional FA during the study. Estrus was synchronized by inserting a vaginal sponge (Spongavet^®) for 12 days + 500 IU equine chorionic gonadotropin (eCG; Gonaser^®), and ewes were inseminated via laparoscopic approach 56-59 h after eCG injection. The size of ovarian structures was assessed by transvaginal ultrasonography at -21, -14, -2, 0, and +10 days. Blood samples were collected weekly to measure the plasma's different biochemical variables and FA profile. Treatment did not affect the amounts of glucose, aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, interleukin-10, interleukin-2, and non-esterified FA (p > 0.05). Conversely, concentrations of triglyceride, cholesterol, tumor necrosis factor-alpha, and insulin-like growth factor-1 were higher in SFA-fed ewes relative to control animals (p < 0.05). LO feeding resulted in greater amounts of n-3 FA isomers in plasma, while higher amounts of stearic acid were detected in SFA fed group 0 and +21 (p < 0.05). The number of ovarian follicles and corpora lutea also were not affected by treatment. Other reproductive variables were not affected by treatment except for the reproductive rate. It seems that LO or SFA feeding of fat-tailed ewes peri-insemination period was not superior to the isocaloric non-additional fat diet provided for the control group during the non-breeding season.

The purpose this study was to investigate the influences of 5% mung bean (Phaseolus aureus L.) on BUN and enzyme activities in serum of hyperlipidemic rats. Sprague-Dawley(SD) rats (24 male) were divided into four groups, namely the BD group(normal-nonhyperlipidemic diet), BM group(normal-nonhyperlipidemic diet+5% mung bean), BH group(control-hyperlipidemic diet), and BHM group(hyperlipidemic diet+5% mung bean). Serum concentrations of blood urea nitrogen (BUN) and uric acid were significantly decreased (p<0.05) by mung bean supplementation diet. The activities of AST, ALT, ALP, LDH, amylase and lipase in sera of mung bean diet group were significantly decreased (p<0.05). The catalase activity in serum of mung bean supplementation group was significantly increased than hyperlipidemic diet (p<0.05). In vivo experiment with hyperlipidemic rats showed that ingestion of mung bean were effective in kidney and hepatic functional enzyme activities. Which suggests that mung bean material could be used for further studies as a potential source for nutraceutical foods.

Background and objective: A new formular CPC22 consists of Cynanchum wilfordii root, Pueraria thomsonii flower, and Citrus unshiu peel and has been developed to improve the postmenopausal symptoms. The research intended to evaluate whether CPC22 would regulate bone loss, hot flashes, and dysregulated lipid metabolism in ovariectomized (OVX) postmenopausal mice. Method: The OVX mice were orally administered with CPC22 daily for 7 weeks. Results: CPC22 regulated OVX-induced bon loss by enhancing serum osteoprotegerin, alkaline phosphatase, and osteocalcin levels and diminishing serum receptor-activator of the NF-κB ligand (RANKL), collagen type 1 cross-linked N-telopeptide, and tartrate-resistant acid phosphatase levels. As a result of CPC22 treatment, notable decreases in tail skin temperature and rectal temperature were observed, along with diminishment in hypothalamic RANKL and monoamine oxidase A levels and enhancement in hypothalamic serotonin (5-HT), norepinephrine, dopamine, 5-HT2A, and estrogen receptor-β levels. CPC22 enhanced levels of serum estrogen and diminished levels of serum follicle-stimulating hormone and luteinizing hormone. CPC22 regulated levels of serum lipid metabolites, including total cholesterol, triglycerides, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol. Furthermore, CPC22 diminished levels of serum blood urea nitrogen, creatine kinase, alanine transaminase, aspartate aminotransferase, and lactate dehydrogenase and restored vaginal dryness without affecting uterus atrophy index and vagina weights. Conclusion: Therefore, these results indicated that CPC22 improves OVX-induced bone loss, hot flashes, and dysregulated lipid metabolism by compensating for estrogen deficiency without side effects, suggesting that CPC22 may be used for the prevention and treatment of post menopause.

Objectives The purpose of this study is to evaluate the fracture healing effect of extracts from Cnidium officinale and Angelica sinensis (CO/AS) in mice with femoral fracture. Methods C57BL/6 mice were randomly divided into normal, control (phospate-bufferd saline), positive control (tramadol), CO/AS extract 40 mg/kg and 80 mg/kg. By using Collier's method, all groups except normal group went through femoral fracture. Aspartate aminotransferase (AST), alanine transferase (ALT), lactate dehydrogenase (LDH), blood urea nitrogen (BUN) and creatinine were measured to evaluate the safety of CO/AS. Hematoxylin & eosin, Safranin O staining, x-ray, tensile and compressive force were conducted to assess the effect of CO/AS on fracture. Results The liver function test showed AST, ALT and LDH in CO/AS at 14th and 28th days were not significantly different compared with control group. The renal function test showed BUN in CO/AS at 14th days and BUN and creatinine in CO/AS at 28th days were significantly decreased compared with control group. The morphological & histological analysis and x-ray showed that CO/AS promoted cartilage and callus formation process compared with control group. The tensile and compressive forces test showed tensile in CO/AS 40 mg/kg and tensile & compressive forces in CO/AS 80 mg/kg were significantly increased compared with control group. Conclusions CO/AS extract showed the possibility that it promotes early fracture union and increases bone tensile and compressive strength, while does not have hepatotoxicity. In conclusion, CO/AS has a potential to promote healing of bone fracture and this study warranted the clinical usage of CO/AS at bone fracture.

Background : Recent studies have shown that stress fundamentally influences the functional modulation of organ and stress-related disease causes high morbidity and mortality rates. Objective : The present research investigated the effect of restraint stress on psychological and physiological responses. Results : Body weight and food intake were changed in stress group. Body weight has continuously decreased, and food intake has been slightly altered. As a result of measuring each tissue's weight, the liver and kidney's weight loss was greater than that of other organs. The lipid profile of stressed animals showed significant increases in cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL), and high-density lipoprotein (HDL) levels compared to control. As hepatic marker enzymes, serum glutamic pyruvic transaminase (GPT; alanine aminotransferase), glutamic oxalacetic transaminase (GOT; aspartate aminotransferase), and lactic dehydrogenase (LDH) were increased in the stress group. However, levels of serum cortisol and corticosterone did not affect. Results of the behavioral tests show that the stress group has increased activity, sluggish movements, and anxiety in the central part compared with the control group through the open field test. In the forced swim test, the stress group models had a longer duration of slowing movement, and its rate also increased. Also, in immunoblotting, stress increased the inflammatory factors Inducible Nitric Oxide Synthase (iNOS), cyclooxygenase-2 (COX-2) and activated the mitogen-activated protein kinase (MAPK) pathway. Conclusions : We observed that mouse model were affected behavioral response and liver injury when exposed to restraint stress, indicating the importance of the restraint stress in the development of psychological and physiological processes.

Background: Hypomagnesemia is a common complication after cardiac surgery with cardiopulmonary bypass. The purpose of this study was to assess the clinical beneficial effect of administration of magnesium sulfate in cardiac surgery. Material and Method: Thirty five patients scheduled for elective cardiac surgery were randomly assigned to magnesium group (n=20) which received magnesium sulfate in priming solution (1 g) and cardioplegic solution (1 g) or control group (n=15) which did not receive it. Arterial blood samples were drawn for measuring $Mg^{++}$ and electrolytes contents, blood gas analysis, CBC, total protein, albumin, blood urea nitrogen (BUN), creatinine, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, tumor necrosis factor-${\alpha}$ $(TNF-{\alpha})$, interleukin-6 (IL-6), interleukin-10 (IL-10), creatine phosphokinase (CpK), creatine kinase-MB (CK-MB), lactate dehydrogenase(LDH), troponin-1 (TNI), prothrombin time (PT) and activated pratial thromboplastin time level (aPTT). Venous blood samples were drawn before and after the operation for measuring activated clotting time level (ACT). Result: $Mg^{++}$ levels in magensium group were higher than those of control group at intraoperative and post-operative periods (p<0.05). dysrhythmias were lower in magnesium group (8 cases out of 17 patients, 46.4%) than in control group (10 cases out of 10, 100%, p=0.050). Conclusion: These results showed that administration of low dose magnesium sulfate during cardiac surgery prevented hypomagnesemia and lowered incidence of dysrhythmia.

This study was conducted to determine the effects of fermented water extracts from Ligularia fischeri (LAF) on reduction of hepatotoxicity induced by ethanol in rats. Ethanol-treated Sprague-Dawley rats were divided into the following eight groups: ethanol-treated group (control), ethanol and ursodeoxycholic acid-treated group (positive control), ethanol and non-fermented water extracts from Ligularia fischeri (LA)-treated groups [100, 200, and 400 mg/kg BW (body weight)], ethanol and LAF-treated groups (100, 200, and 400 mg/kg BW). ${\gamma}$-Glutamyl transferase activities of the ethanol+LA-treated (100, 200, and 400 mg/kg BW) groups and ethanol+LAF-treated (400 mg/kg BW) group decreased significantly compared to those in the control group (P<0.05). Aspartate aminotransferase activities of the ethanol+LAF-treated (100, 200, and 400 mg/kg BW) groups and ethanol+LA-treated (200 and 400 mg/kg BW) groups decreased significantly compared to those in the control group (P<0.05). Alanine aminotransferase and lactate dehydrogenase activities of all groups significantly decreased compared to those in the control group (P<0.05). The total cholesterol, low density lipoprotein-cholesterol, and triglyceride levels of all groups tended to decrease compared to those in the control group, but the differences were not significant. Superoxide dismutase activity of liver tissues was enhanced in the ethanol+LAF-treated (400 mg/kg BW) group (P<0.05). The contents of malondialdehyde in liver tissues decreased in the ethanol+LAF-treated groups (P<0.05). All treated groups showed well preserved lobular architectures with no evidence of steatosis or liver damage compared to the control group. As the results of this study, LAF may improve the plasma lipid profile and alleviate hepatic damage by ethanol.

Perilla frutescens usually dieted in East Asian country such as Korea and Japan. Antioxidant, antiinflammatory and anticancer activities of perilla leaves have been founded. In previous study, we confirmed that caffeic acid, major compound of perilla, was accumulation by sucrose aqueous solution and thus antioxidant effect of perilla was enhanced. In this study, we investigated the protective effect of functional perilla leaves extract (PLE) against tert-butyl hydroperoxide(t-BHP) induced-oxidative hepatotoxicity. The pretreatment with PLE (250, 500 and 1000 mg/kg b.w.) for 5 days before a single dose of t-BHP (i.p.; 0.5 mmol/kg) significantly lowered the serum levels of aspartate aminotransferase, alanine aminotransferase and lactate dehydrogenase dose-dependently. And we confirmed that the indicators of oxidative stress were remarkably reduced in the liver, such as the glutathione contents and malondialdehyde, marker of lipid peroxidation. Pathological histology of the rat livers tissues showed that PLE reduced the hepatocyte degeneration and neutrophilic infiltration of liver induced by t-BHP. These results suggest that functional perilla frutescens has the protective effect of liver against t-BHP-induced oxidative hepatic stress in rats.

This study was designed to observe the effects of feeding the mixed oils of the sardine oil containing n-3 EPA, DHA and the safflower oil which is rich in n-6 linoleic acid on the improvement of the lipids and enzyme activities of serum in rats. Experimental oils mixed with 16% butter (control group) and 8% butter + 8% olive oil, 8% butter and various level of sardine and safflower oils were administered to the male rats of the Sprague Dawley for 4 weeks. The activities of aspartate aminotransferase (AST, EC 2.6.1.1), alanine aminotransferase (ALT, EC 2.6.1.2), lactate dehydrogenase (LDH, EC 1.1.1.27) and alkaline phosphatase (ALP, EC 3.1.3.1) in serum were significantly decreased in the all experimental groups than in the control groups, and activities of ALT and LDH were remarkably lower in the group 5 (4% sardine 0il + 4% safflower oil). Concentrations of total cholesterol and HDL-cholesterol in serum were lower in the other groups than in the dontrol groups, and particularly, lowest in the group 5. Concentrations of LDL, LDL-cholesterol, phospholipid and triglyceride in serum were lower in the all experimental groups than in the control group. Concentrations to total cholesterol and cholesteryl ester in serum were lowest in the group 5. The ratio of cholesteryl ester to total cholesterol was remarkably high in the control group, while group 2 (8% olive oil) was the lowest. From this results, the feeding equal quantity mixed oil with n-3 PUFA rich sardine oil and n-6 PUFA rich safflower oil were effective on the improvement of the lipid composition in the serum. It might be due to the effects of appropriate ratios of P/S, 0.85 and n-6/n-3P, 2.85 in the test lipids.

This study aimed to evaluate the protective effect of Orostachys malacophyllus (OM) and fermented O. malacophyllus (FOM) in Sprague-Dawley rats who had been intoxicated with 1% (w/w) orotic acid (OA) for 10 days. The activities of several hepatic enzymes, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), and cholinesterase, were increased when OA was given, but these parameters were significantly decreased by FOM treatment. In addition, OA treatment resulted in an increased lipid peroxidative index (thiobarbituric acid-reactive substances, TBARS). A worsened antioxidant status (reduced glutathione) in the liver and serum was also observed. FOM treatment improved the antioxidant status of OA-induced fatty-liver rats, which was evaluated by decreased levels of the lipid peroxidative index and improved antioxidant status in the liver and serum. The contents of liver non-heme iron were increased with OA treatment and significantly decreased with FOM treatment, which suggested that the lipid peroxidation contents were inversely correlated with liver non-heme iron content. Based on these results, FOM is considered a material with significant potential for development into a functional health food that can improve fatty-liver conditions.
