الوصف: In Taiwan the kiwifruit Actinidia setosa grows higher than 1,500 in above sea level. The National Chung Hsing University of Taiwan maintains a collection of experimental vines grown from cuttings of the native A. setosa collection. Actinidia setosa 'No.9', which produced the largest fruit, was selected for a study of its physicochemical and antioxidant characteristics, which were compared with those of A. deliciosa 'Chung Hsing No.3' and 'Chung Hsing No.4'. Kiwifruit fresh weight, soluble solids content, flesh firmness, titratable acidity, quinic, malic, ascorbic and citric acid contents, chlorophyll content, total phenol compound content, peroxidase activity, polyphenolic oxidase activity, free radical scavenging (DPPH) effect, and chelating effect were measured. Anthesis of A. selosa and A. deliciosa occurs in late April and late May, and fruit maturity Occurs in late September and late October, respectively. The strong insect and diseaseresistant characteristics of A. selosa 'No.9' can be attributed to the long down on the branches, leaves, and fruit. ACIinidia setosa 'No.9' has a yellow rust leaf infection rate of 14 +/- 3% while that of 'Chung Hsing NoY and 'Chung Hsing No.4' leaves was 77 +/- 5% and 92 +/- 7%, respectively. The A. setosa 'No.9' fruit has a flat, long shape with a down length of 33 +/- 4 mu m, and the down length on 'Chung Hsing No.3' and 'Chung Hsing No.4' fruit was 18.2 +/- 0.7 and 17 +/- 4 mu m, respectively. Under organic cultivation, A. selosa 'No. 9' had a mature fruit fresh weight of 66 +/- 10 g, Soluble solids content of 6.2 +/- 0.1 'Brix, and titratable acidity of 2.2 +/- 0.0%. In A. setosa 'No.9' the ascorbic acid concentration was 83 +/- 6 mg/100 g, inalic acid was 565 9 mg/100 g, and the total phenol Compound content was 0.4 +/- 0.1 rng/g of fresh weight, all significantly higher than those of 'Chung Hsing No.4'. The peroxidase and polyphenolic oxidase activities of A. selosa 'No.9' were 0.02 +/- 0.0 Delta A(470)/min/g.fw and 0.01 +/- 0.0 Delta A(420)/min/g.fw at 150 days after ...

الوصف: The effects of spirulina supplementation on preventing skeletal muscle damage on untrained human beings were examined. Sixteen students volunteered to take Spirulina platensis in addition to their normal diet for 3-weeks. Blood samples were taken after finishing the Bruce incremental treadmill exercise before and after treatment. The results showed that plasma concentrations of malondialdehyde (MDA) were significantly decreased after supplementation with spirulina (P < 0.05). The activity of blood superoxide dismutase (SOD) was significantly raised after supplementation with spirulina or soy protein (P < 0.05). Both of the blood glutathione peroxidaes (GP (x) ) and lactate dehydrogenase (LDH) levels were significantly different between spirulina and soy protein supplementation by an ANCOVA analysis (P < 0.05). In addition, the lactate (LA) concentration was higher and the time to exhaustion (TE) was significantly extended in the spirulina trail (P < 0.05). These results suggest that ingestion of S. platensis showed preventive effect of the skeletal muscle damage and that probably led to postponement of the time of exhaustion during the all-out exercise.
