  • A series of 3-[1-(4-(2-methylpropyl) phenyl) ethyl]-1,2,4-triazole-5-thione (I) and its bicyclic condensed derivatives 6-benzylidenethiazolo[3,2-b]-1, 2,4-triazole-5(6H)-ones (IIa-IIf) were investigated for the prevention of ethanol-induced oxidative stress in liver and brain of mice. Administration of ethanol (0.1 mL/mice, p.o.) resulted in a drop of total thiol groups (T-SH) and non-protein thiol groups (NP-SH), and an increase in thiobarbituric acid reactive substances (TBARS) in both liver and brain tissue of mice (p<0.001). Among the compounds investigated (at a dose of 200 mg/kg, p.o.), I and IId ameliorated the peroxidative injury in these tissues effectively. Compounds IIa, IIc and IIe improved the peroxidative tissue injury only in brain. These findings suggest that certain condensed thiazolo-triazole compounds may contribute to the control of ethanol-induced oxidative stress in an organ selective manner.

  • This study aims to evaluate the therapeutic action of administration of Nigella sativa (NS) and Peganum harmala (PH) oils in diabetes and hepatic toxicity. Results show that treatment of diabetic rats with NS oil or PH oil ameliorate hyperglycaemia induced stress oxidative and hepatic dysfunction in diabetic rats. Administration of NS or PH oil to diabetic rats caused an anti-diabetic and antioxidant activities by the decrease in plasmatic glucose level and increase in hepatic superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPX) activities, reduced glutathione (GSH) and glycogen contents compared to untreated diabetic rats. Besides, NS and PH oils protect the hepatic function observed by decrease of triglyceride (TG), total cholesterol (TCh), and increase of high density lipoprotein-cholesterol (HDL-Ch) levels in serum and hepatic tissues. Moreover, a diminution in the bilirubin, transaminase glutanic pyruvic (TGP), and transaminase pyruvic oxaloacetic (TPO) contents in serum and the thiobarbituric acid-reactive substances levels (TBARs) in hepatic tissues are also detected.

  • The antioxidant properties of methanolic extracts (PM) from the fruit of Prunus mume after liquor manufacturing were determined in a chicken breast meat system. When PM was added to chicken breast meat, 2-thiobarbituric acid-reactive substances (TBARS) value at day 3 was decreased by about $25\%$ compared to control meat without PM. PM did not significantly affect the color of chicken meat compared to the control. The amounts of volatile aldehydes and hydrocarbons were decreased by the addition of PM. Hexanal was the predominant volatile compound in the control, accounting for the majority of total volatiles; PM reduced the amount of hexanal to $81\%$of that in the control meat at 3 days.

  • The aim of this study is to determine the some physicochemical (proximate composition, pH and $a_w$ values) and reconstitution (wettability, dispersibility and solubility index (SI)) properties of spray-dried bone broth powder (BBP) along with the effects of the addition of different carrier agents. Subsequently, the powdered products were stored to determine the storage stability (pH, lipid oxidation, color, browning index) for 3 mon at $-18^{\circ}C$. For this purpose, firstly marrow-containing bones (Os femur and Os humerus) have been boiled to get the bone broth. Three different emulsions were respectively prepared (1) 20% maltodextrin (MD) added BBP, (2) 20% whey powder isolate (WPI) added BBP and (3) 10% MD and 10% WPI added BBP and the emulsions were dried using a spray-dryer with $185^{\circ}C$ inlet and $95^{\circ}C$ outlet temperature. The proximate composition and reconstitution properties of BBP were found statistically different (p<0.05) depending on the use of different carrier agents. MD added BBP showed uniform and smooth morphology. The color, browning index, thiobarbituric acid reactive substances (TBARS) and pH values of BBP significantly changed (p<0.05) during storage. In conclusion, both the results of physicochemical and storage period analyses showed that the most suitable encapsulation material in the production of the bone broth powder is MD.

  • Fumonisin B1 (FB1) structurally resembles sphingolipids and interferes with their metabolism leading to sphingolipid dysregulation. We questioned if FB1 could exacerbate liver or kidney toxicities in glutathione peroxidase 1 (Gpx1) and catalase (Cat) knockout mice. While higher serum levels of thiobarbituric acid reactive substances (TBARS) and sphinganine (Sa) were measured in Gpx1/Cat knockout mice (Gpx1/Cat KO) than wild type mice after 5 days of FB1 treatment, serum levels of alanine aminotransferase (ALT), sphingosine-1 phosphate (So-1-P), and sphinganine-1 phosphate (Sa-1-P) were found to be relatively low. Although Sa was highly elevated in Gpx1/Cat KO mice and wild mice, lower levels of So and Sa were found in both the kidney and liver tissues of Gpx/Cat KO mice than wild type mice after FB1 treatment. Paradoxically, FB1-induced cellular apoptosis and necrosis were hastened under oxidative stress in Gpx1/Cat KO mice.

  • Physiological functionalities of water and ethanol extracts from Basil were determined. The concentration of total phenolic compounds of the water and ethanol extracts were $286.0\;{\mu}g/ml$, $250.0\;{\mu}g/ml$. Antioxidant activities of Basil extracts were determined using 2,2'-azinobis (3-ethyl benzothiazoline-6-sulfonic acid) radical cations (ABTS), 2,2-diphenyl-1-picryl hydrazyl radicals (DPPH), antioxidant protection factor and thiobarbituric acid reactive substances. The total antioxidant activities of Basil extracts using ABTS were 96.8% in the water extracts and 94.7% in the ethanol extract, DPPH were 87.0%, 93.9%, PF were 0.69, 1.16 and TBARS were $0.2{\times}10^{-3}\;{\mu}M,\;0.6{\times}10^{-3}\;{\mu}M$. Angiotensin converting enzyme inhibitory activity and xanthine oxidase inhibitory activity of Basil were higher in ethanol extracts (99.7%, 100.0%) than those of water extracts (39.9%, 54.7%). Phenolic profiles in Basil extracts were analyzed using HPLC. The result was that among the 6 phenolics, rosemarinic acid was the highest in ethanol extracts.

  • The purpose of this study was to investigate the effects of the sausage containing mulberry leaf(0.04%, 0.08%) and persimmon leaf powder(0.04%, 0.08%) on lipid oxidation(Thiobarbituric Acid Reactive Substances, TBARS), nitrite, volatile basic nitrogen(VBN) and fatty acid composition. The TBARS values of sausage containing mulberry leaf and persimmon leaf powder were not significantly different(p > 0.05) as compared to control during 45 days of storage, but TBARS values of sausage containing 0.04% mulberry leaf and persimmon leaf powder were significantly lower than those of control at 60 days of storage. The nitrite scavenging ability of sausage containing mulberry leaf and persimmon leaf powder was higher than that of control. The VBN content of all treatments significantly increased(p < 0.05) during the storage periods. In fatty acid compositions, the percentages of PUFA/SFA of sausage containing mulberry leaf and persimmon leaf powder were significantly higher as compared to control. In conclusion, sausage containing mulberry leaf and persimmon leaf powder was a more effective natural resource on the basis of the lipid oxidation and nitrite scavenging ability of sausage.

  • Press ham were manufactured to investigate the effects of ginseng powder on quality characteristics of press ham. Each treatment added pork loin basis with Ginseng powder(0, 0.5, 1.0, 1.5 and 2.0%) were stored until 28 days at 4℃. The changes in shear force value, thiobarbituric acid reactive substances (TBARS), fatty acid composition and sensory evaluation of each treatment were measured until 28 days at 4℃. Shear force value was not significantly different between the control and ginseng treatment groups. The value for all treatments were decreased significantly by the passage of storage time (P<0.05). Remarkable differences were found in sensory properties(color, flavor and acceptability) among control and ginseng treatment groups. This was not clearly changed by the passage of storage time. Ginseng treatment groups showed significantly (p<0.05) lower TBARS value than the control. TBARS value was increased significantly during storage in all treatments. Fatty acid composition did not significantly differ between the control and ginseng treatment groups. Summing up the a forementioned results, press ham manufacturing with ginseng powder was not affected in shear force value, sensory evaluation, TBARS and fatty acid composition. Also, it may be assumed that the high quality press ham can be manufactured with the extend of storage period and saponin accumulation.

  • This study was undertaken to elucidate the effect of DHA rich fish oil(DHA rich oil) added to different dietary fats on thrombosis and lipid peroxidation. Rats were fed perilla oil, sesame oil and beef tallow with or without DHA rich oil for 12 weeks. Bleeding time was the longest in Perilla oil groups with or without DHA rich oil. The productions of thromboxane B2(TX B2) and 6-keto Prostaglandin F1$\alpha$(6-keto PG F1$\alpha$) were the highest in Esame oil group without DHA rich oil. Bleeding time tended to be extened and group showed the most antithrombotic effect among three oil groups when DHA rich oil added. The antithrombotic effect by DHA rich oil addition seemed to be resulted from the increase of dietary n-3 fatty acid rather than DHA. And there was not the difference in antithrombotic effect between DHA and $\alpha$-linolinic acid. The level of TBARS(thiobarbituric acid reactive substances) in plasma and liver, and the activities of lipid peroxide metabolizing enzymes(catalase, superoxide dismutase and gluthathion peroxidase) in erythrocyte and liver were not affected by the dietry fat type and DHA rich oil addition, except that activity of hepatic catalase was increased by DHA rich oil addition. Therefore it revealed the DHA level added in this study seldom affected lipid peroxidation. However, it dose not conclude that DHA level of this study make low production of lipid peroxide because the peroid of our study was short.

  • This study was performed to investigate the effect of a sequencial washing of organic acid and distilled water on meat quality and the population of Escherichia coli of pork loin during cold storage. E. coli ATCC25922 was inoculated on the surface of sliced pork loin and 50 mL of 1% or 2% of organic acid and the same amount of distilled water was sprayed on the surface of pork loin. Then, physicochemical and microbial properties of pork loin were analyzed during cold storage. During storage period, lightness, yellowness and lipid oxidation (thiobarbituric acid reactive substances value) was higher than those of not treated control. However, the population of E. coli was decreased significantly in formic acid and distilled water sprayed pork loin samples. From these results, it can be considered that application of combination of washing of formic acid and water in the washing step of pig slaughter may be helpful to control the proliferation of E. coli.
