[Effect of lycopene on oxidative stress and behavioral deficits in rotenone induced model of Parkinson's disease].

Objective: To investigate the neuroprotective potential of lycopene on oxidative stress and neurobehavioral abnormalities in rotenone induced Parkinson' disease (PD).

Methods: Forty adult C57BL/6 mice were randomly divided into four groups (n = 10): control, lycopene (10 mg/kg body weight, orally), rotenone (3 mg/kg bw, intraperitoneally) and rotenone plus lycopene, which were sacrificed for 5 weeks. The spectrophotometry was used to determine the activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT) and the content of malondialdehyde (MDA) in substantia nigra and right striatum.

[Effects of stem numbers per ground area on the quality of standard cut Chrysanthemum morifolium in greenhouse: simulation model].

In order to understand the effects of stem numbers per ground area on the quality of standard cut Chrysanthemum morifolium, an experiment with different cultivars, different stem numbers per plant, different planting densities, and different planting dates was conducted in a greenhouse in Shanghai in 2005 and 2006. The effects of stem numbers per ground area on the canopy leaf area index and external quality of standard cut C. morifolium were quantified using the experimental data.

[Quality prediction model of greenhouse standard cut chrysanthemum based on light-temperature effect].

Based on the effects of light and temperature on chrysanthemum quality and the experiments with different chrysanthemum varieties and planting dates, a quality prediction model of greenhouse standard cut chrysanthemum with the physiological product of thermal effectiveness and PAR (PTEP) as the measurement scale was developed and validated. The results showed that the predicted results, including the number of unfolding leaves, leaf area, plant height, stem diameter, internode length and flower diameter, accorded well with the observed ones, and the determination coefficient (R2) and relative prediction error (RSE) based on 1 : 1 line were 0.99, 0.

[Effects of Zhikeping on aortic oxyradical and the expression of ICAM-1 in a rat model of experimental early atherosclerosis].

Objective: To investigate the effects of Zhikepingon the oxyradical andintercellular adhesion molecule-1 (ICAM-1) of experimental early atherosclerosis.

Method: The model of SD rat early atherosclerosis was induced by cholesterol diet. The suspension of Zhikeping and simvastatin were administered intragastrically, respectively.
