To develop a new functional fruit wine, quality characteristics and physiological functionality of wild grape wine (WGW) were investigated and compared with that of foreign grape wine (FGW). Ethanol contents of WGW was 11.0%, similar to that of FGW(10.6%), but total acidity(0.67%) and total anthocyanin content($A_{520}$: 0.32) of WGW were higher than those of FGW(0.4%, 0.22). Antioxydant activity and SOD-like activity of WGW which is related in anti-aging functionality were 93.6% and 53.0%, respectively, higher than those of FGW(85.9%, 42.5%). from this results, we concluded domestic wild grape wine is very excellent functional fruit wine.

This expriment was carried out on culture media which affect growth, development and physiological effect to Pleurotus ostreatus, when aqueous ferrum, red pepper powder, leaves of ginkgo biloba were added to culture media. The yield of fresh mushroom per 850ml PP bottle in chunchu-neutari was highest by 144g in 34.9g aqueous ferrum added, ferrous content don't affected to yield of mushroom, but variety of Pleurotus ostreatus affect to yield. Mineral content of fruit body and culture media in Suhan-neutari was different to mineral kind, ferrous content of furit body was similar to 0.31~0.43mg/kg when ferrous content of media was increased in 0.89mg/kg to 10.8mg/kg. The more content of red pepper powder in culture media was high, the more capsaicin content in fruit body was high. transferred capsaicin was highest by 6 mg/100g in Suhan-neutari. Total phenolics content were higher in culture media which was added aqueous ferrum and red pepper powder, but correlation don't showed total phenolics content among antioxydant activity, reducing power, chelating capacity. Macrophage activation was higher in Suhan-neutari than other Pleurotus spp.

Carcinogenesis can be theoretically divided to intiation step and promotion step. Intiation associates with genetic alterations including p53 tumor suppressor gene and ras oncogene. Promotion involves in clonal expansion of of an initiated cell by epigenetic mechanism, mainly through signal transduction and gene expression. Ultraviolet light (UV) acts as both initiator and promoter. Initiation is closely related with DNA damage induced by UV, including cyclobutane pyrimidine dimers, (6-4) photoproducts and 8-hydroxy-2'-deoxyguanosine. Cyclobutane pyrimidine dimers and (6-4) photoproducts are directly induced by UV, while 8-hydroxy-2'-deoxyguanosine is induced indirectly by the reactive oxygen species. Because initiation is an irreversal genetic event, while promotion is a reversal and epigenetic event, to know the molecular mechanisms of tumor promotion in UV-carcinogenesis is crucial to develop preventive medicine and suppress UV-carcinogenesis. Because ROS is also involved in signal transduction of the cell, anti-oxidant could be the good candidate of anti-promoting agent. Here, we describe the suppressive effect of UV-carcinogenesis by various anti-oxidant including olive oil. In addition, we discuss about the mechanism of UVB-induced expression of cyclooxygenase-2, which might be a representative molecule involved in promotion of UV-carcinogenesis.

Objective: The present experiment has tested the effect of dietary alfalfa flavonoids (AAF) supplementation on the productive performances, carcass characteristics, meat quality and lipid oxidation of growing rabbits. Methods: One hundred and sixty crossbred rabbits (42 days old) were divided into four groups of forty animals each and were fed either a control diet (AAF0) or an AAF0 diet supplemented with 400, 800, or 1,200 mg of AAF/kg per diet (AAF4, AAF8, and AAF12, respectively) from weaning to slaughtering (102 days old). Performance data were recorded over a period of 60 days. At the end of the trial, 12 rabbits were slaughtered per group, and the carcass characteristics were recorded. Moreover, the plasma, liver and dorsal muscles were sampled from 12 rabbits/group, and were analyzed for lipid oxidation. Results: No significant differences were recorded for the performance, carcass characteristics and meat quality traits except for lightness parameter that was lower in the control group. Dietary AAF supplementation significantly (p<0.01) affected the malondialdehyde (MDA) levels of the frozen meat in a dose-related manner, with the lowest value (0.24 mg MDA/kg fresh meat) recorded in the AAF12 group samples. Conclusion: These findings indicated that the dietary inclusion of AAF in rabbit diets improved muscle oxidation stability with no adverse effects on the growth performance of the animals even if a slight impact on meat lightness color parameter was recorded.

The strains of Panax ginseng C.A. Mey., P. quinquefolius L. and selected strains P. ginseng-B, P.ginseng-A, P. quinquefolius-C were investigated. Activities of SOD, catalase and peroxydase were determined by methods of Fridovich et al. (1979), Komov et al.(1975), Bovaird et al.(1982) respectively. Activities of SOD, catalase, peroxydase were investigated every day 5 in cycle of cultivation. For P. ginseng it was the 35 days, P. quinquefolius the 70 days, P. quinquefolius-C 90 days. P. ginseng-B 90 days, P. ginseng-A 60 days. The P. quinquefolius, P. quinquefolius-C, P. ginseng-B had clear differentiation and developed tracheid elements, which are absent in strain of P. ginseng. The peaks of protein content for P. ginseng (4.5 units/g) and for P. quinquefolius (3.5 units/g) were on day 10 and remained unchanged till the last cultivation. The strain P. ginseng-A had two peaks of protein content (2.5 mg/g) on day 15 and on day 30. For P. ginseng-B strain these peaks were on day 5 and day 40 (3.5 mg/g). Peroxydase activity peak (60 units/g) in P. ginseng strain was on day 10. This activity in P. ginseng-B had two peaks on day 15 and day 35 and reached 95 units/g , increasing to 150 units/g to day 80. In strain of P. ginseng-A was only one maximum of this activity -130 units/g on day 45. In P. quinquefolius peroxydase activity was 103 units/g on day 40, increasing to 135 units/g to day 90. For P. quinquefolius-C this activity peak was 136 units/g on day 60. Peroxydase activities for the upper and lower layers of biomass was different and varied considerably from 28-35 units/g in lower to 270-290 units/g for upper layer. The SOD activity had two peaks in P. ginseng strain the 80 units/g and the 70 units/g on day 20 and day 35 respectively. Activity of SOD in P. quinquefolius strain reached 53 units/g on day 40 and increased up to 83 units/g to day 60.The similar increase of SOD activity was marked for P. ginseng-B to 85 units/g on day 90. In P. ginseng strain the 6 molecular isoforms SOD was defined. One of them with RfO,6 was determined in all days of cycle, three other (Rf-0.43; 0.54;0.80) only on day 10 and day 20. The isoform of SOD with Rf-0,29 was detected only on day 10 and with Rf-0,35 only on day 35. The catalase activity decreased in all strains to the last days of cultivation. The changes of SOD, catalase and peroxydase activities reflect the differences between the strains of Panax ginseng and Panax quinquefolius and their selected forms. The correlation between maximum life span of strains and activities of their antioxydant enzymes were detected.
