[Effects of LED qualities on quality and antioxidation capacity of eggplant fruits].

The effects of red light, blue light, red+blue light and white light (control) generated by LED on the quality and antioxidation capacity of fruit and yield of ' Brita' eggplants were stu died. The results showed that under blue LED, the soluble protein, free amino acids contents o eggplant pulps and the anthocyanin content of eggplant peels were significantly higher by 15.1%, 27.

[Effects of silicon on photosynthetic characteristics and activity of antioxidant enzymes in continuous-cropped cucumber seedlings].

The effects of spraying exogenous silicon (Si) (0, 1, 2, 3, 4 and 5 mmol L(-1)) on the growth, photosynthetic characteristics and activity of antioxidant enzymes in continuous-cropped 'Jinyan No. 4' cucumber seedlings were studied. The results showed that with the application of 1-3 mmol x L(-1) Si, electrolyte leakage (EL) and malondialdehyde (MDA) content in leaves were significantly decreased, while the contents of chlorophyll a (Chl a), chlorophyll b (Chl b), carotenoids (Car), chlorophyll (a+b) and photosynthetic rate (Pn) in leaves were significantly improved, the activities of superoxidase (SOD), peroxidase (POD), catalase (CAT) and ascorbic acid peroxidase (APX) were significantly increased, and the plant height, stem diameter and dry mass accumulation of cucumber seedlings were promoted.

[Clinical application of 16-slice spiral CT coronary angiography].

Objective: To assess the clinical value of multislice spiral CT coronary angiography (MSCTCA).

Methods: Totally 79 patients were examined with MSCTCA and the CT images were reconstructed by several methods to analyze the factors crucial for the image quality, the ability of MSCT displaying the coronary artery vessels, along with the nature and calcification degrees of the plaques. The presence as well as the degree of vascular stenosis, visualization of the bypass graft, implanted stents and patency of the vessels were evaluated.
