Background: Lipid peroxidation is considered that is one of the causes of pathological processes. Green bean is not only a food of high economic value but also a good medicine. Objective: To investigate the effects of green bean on (1) the lipid peroxidation in mitochondria of rat liver cell, (2) the index in blood of rabbits exposed to radiation: the activities of antioxidant enzymes (SOD, GPx), concentrations of MDA and TAS. Subjects and methods: In vitro experimental model was used to estimate the effects of green bean on lipid peroxidation in mitochondria of rat liver and in vivo experimental model was used to investigate the effects of green bean on the activities of free radicals in blood of rabbits exposed to radiation. Results and Conclusions: (1) Total green bean decreased the lipid peroxidation in mitochondria of rat liver cell without dependence onagents induced lipid peroxidation such as Fe3+.ADP/NADPH or Cumene hydroperoxid, (2) Green bean concurrently inhibited the decreased activities of SOD, GPx, TAS and the increased concentration of MDA in blood of rabbits radiated with 5 Gy dose. \r\n', u'\r\n', u'\r\n', u'

43 people in 30 days before and after oral use of BELAF were studied. Results: blood red cell superocid dismistase (SOD) activation increased (691.7106.46 versus 984.23102.98 U/g Hb), white blood red cell glutathion peroxidase (GPx) and glutathion reductase (GR) had not any change obviously. The plasma total antioxidant state enhanced, MDA level decreased, ChE activetion enhanced. The study showed that BELAF could help to improve the state of antioxidation in blood red cell and in plasma of workers of chemical production

The purpose of the present study was to investigate the effects of resveratrol supplementation on oxidative damage and lipid peroxidation induced by strenuous exercise in rats. The rats were randomly divided into five groups: a sedentary control group, an exercise control group, and three treatment exercise groups administered increasing doses of resveratrol (25, 50, and 100 mg/kg body weight). Resveratrol was administered by oral gavage once daily for four weeks. At the end of the four-week period, the rats performed a strenuous exercise on the treadmill, and the levels of lactate dehydrogenase (LDH), creatine kinase (CK), malondialdehyde (MDA), 4-hydroxy-2-nonenal (4-HNE), and 8-hydroxy-2\'-deoxyguanosine (8-OHdG) were measured. The results showed that resveratrol supplementation had protective effects against strenuous exercise-induced oxidative damage and lipid peroxidation by lowering the levels of LDH, CK, MDA, 4-HNE, and 8-OHdG in the serum or muscle of rats. These beneficial effects are probably owing to the inherent antioxidant activities of resveratrol.

OBJECTIVETo study the effect of light intensity on physiological and biochemical characteristics of Chrysanthemum morifolium at the vegetative stage.

METHODThe dynamic response of physiological and biochemical indexes of Ch. morifolium were measured under different treatments (100%, 80%, 60%, 40% and 20% of the full sunlight) at the vegetative stage.

RESULTThe physiological and biochemical indexes of Ch. morifolium showed dynamic changes with the progress of growth and the increase of the treatment time. The soluble sugar content decreased when the light intensity reduced, and had a significant positive correlation with the light intensity. Soluble protein content rose firstly and fell later, malondialdehyde content increased, superoxide dismutase and catalase activity decreased initially and increased afterwards.

CONCLUSIONProper shading benefits the nitrogen accumulation of Ch. morifolium at the vegetative stage, and reduces the strength of stress condition. The suitable light environment for growth of Ch. morifolium at the vegetative stage is about 80%-60% of full sunlight and the optimum treatment time is 20-40 days.

OBJECTIVEThe aim of the work was to study the change for blood pour into the artery fascial flap and oxygen metabolic in tissue that knew the process of the flap.

METHODSWe do the artery fascial flap in the rabbit, then measured the skin capillary blood flow and the content of the MDA.

RESULTSThe content of the MDA rise when the blood flow descends in the flap, but it lives well.

CONCLUSIONSThat the content of the MDA rise as time the blood flow descend in the flap is a gradual process of the whole flap from tip to end, the flap will not appear necrosis until the MDA reach a rather degree.

This study was aimed at evaluating the antioxidant activities of methanol extract of Thamnolia vermicularis. The antioxidant activity, reducing power, superoxide anion radical scavenging and free radical scavenging activities were studied. The antioxidant activity of the extract correlated with its concentration (0.2~2 mg/ml) in the reaction mixtures containing linoleic acid. Upto 67% of lipid peroxidation was inhibited by 2 mg/ml of the lichen extract. The extract showed strong free radical scavenging activity similar to that of BHA (positive control) in a manner of concentration dependent. The lichen extract also showed moderate effects on superoxide anoin scavenging activity and reducing power, which was not so effective as that of Quercetin and BHA used as positive controls. This study suggests that T. vermicularis lichen can be used as a novel source of natural antioxidant.
