蘑菇常见病虫害防治技术

蘑菇是一种高蛋白、低脂肪、低热量、营养丰富、味道鲜美的碱性食物,经常食用能提高人体免疫能力,具有延年益寿之功效,市场前景十分广阔．但在蘑菇生产中常有减产以至于效益不理想现象,究其原因多是由于连续栽培,生态条件恶化,病虫害滋生蔓延严重难以控制造成的．

浙江养殖鱼类暴发性流行病病原的研究——Ⅰ.嗜水气单胞菌(Aeromonas hydrophila)的分离、致病性及生理生化特性

从患病鲫、鲢、鳙、鳊等鱼体上分离出一菌株,经腹腔注射及浸泡感染,能引起鱼患典型的出血病症和死亡,其半数致死量(LD_(50))为1.48×10~5个菌/鱼.该菌发酵分解糖类,氧化酶和过氧化氢酶实验为阳性,具极生单鞭毛,革兰氏阴性,对弧菌抑制剂不敏感,经生理生化特性测定及形态、培养特征观察,确认为嗜水气单胞菌(Aermonas hydrophila).并测定了该菌对抗生素的敏感性及生长特性。

Differences in body composition and risk of lifestyle-related diseases between young and older male rowers and sedentary controls

Abstract

The aim of this cross-sectional study was to compare body composition and risk factors of lifestyle-related diseases between young and older male rowers and sedentary controls. Healthy males aged 19–73 years participated in the study, and were divided into four groups: 26 young rowers, 24 senior rowers, 23 young sedentary controls, and 22 senior sedentary controls. Total and regional lean soft tissue, fat mass, and bone mineral density were measured using dual-energy X-ray absorptiometry. The HDL-cholesterol of senior rowers (67.4 ± 13.4 mg · dl^?1) was significantly (P < 0.05) higher than that of senior sedentary controls (59.2 ± 11.9 mg · dl^?1), while HDL-cholesterol was similar in senior rowers and young rowers (66.1 ± 10.8 mg · dl^?1). Arm, leg, and trunk lean soft tissue mass were significantly higher in senior rowers (5.6 ± 0.6 kg, 18.2 ± 1.8 kg, and 27.3 ± 3.2 kg respectively) than in senior sedentary controls (5.1 ± 0.4 kg, 16.3 ± 1.4 kg, and 24.6 ± 1.7 kg respectively; P < 0.05). Bone mineral density was also significantly higher in senior rowers than in senior sedentary controls (ribs, lumbar spine, and pelvic segments; P < 0.05). We conclude that age-related increases in the risk of lifestyle-related diseases, such as osteoporosis and sarcopenia, are attenuated in male rowers. These results suggest that regular rowing exercise may have a positive influence in the prevention of lifestyle-related diseases in older Japanese people.
