武威市某规模牛场汉和牛犊牛腹泻诊断及综合防治

犊牛腹泻是一种在规模化养牛场中的常见易发病,由于发病病因复杂,如果在第一时间内不能及时做出准确诊断,做好有效治疗,将会造成牛场的快速感染,带来一定的经济损失。本文通过对武威市某规模牛场“汉和牛”犊牛腹泻的病原调查,采集病样进行检测分析,摸清引起该场犊牛腹泻的病原体,根据养殖场实际情况,通过临床和实验室诊断方法,并研究探讨出具体可行的治疗和预防措施。     

不同青贮处理对苦荞麦品质及营养成分的影响

目的：研究不同青贮处理对荞麦秸秆的感官性状及营养品质的影响。方法：将不同比例的玉米面、米糠、糖蜜和玉米秸秆加入荞麦秸秆中混合青贮,从感官、pH值、氨态氮和营养成分等方面进行分析评价。结果：与对照组相比,各处理组均不同程度地改善了青贮品质。从pH值和氨态氮含量来看,30%混合玉米青贮组效果最好;4%米糠组的粗蛋白（5.74%）含量显著高于其他处理组(P<0.05);5%糖蜜组和30%混合玉米青贮组的粗脂肪含量显著低于其他三个处理组(P<0.05)。结论：综合比较感官性状和营养品质,5%糖蜜和4%米糠处理条件下,青贮品质总体效果较好,是荞麦秸秆饲用前处理的可行途径之一。

母猪不孕症的针灸治疗

针灸治病是通过刺激腧穴,疏通经络,以调节机体的阴阳气血、脏腑功能、体表肌肤及筋骨百骸得以濡养等,使其发挥正常的生理功能,从而达到治疗疾病的目的。主要对性成熟后不孕母猪进行针灸治疗,结果其机体恢复正常,且正常受孕而产仔。表明针灸治疗对母猪不孕症的治疗具有重要的指导和参考意义。     

奶牛蹄病的治疗

将患有蹄病的牛按病情严重程度分三级,在每级中各选出12头,并将36头随机分成4组,每组共9头。第1组为对照组,第2组每头牛日粮中加35%石粉18g,第3组每头牛日粮中加硫酸锌1.2g,第4组每头牛日粮中同时加35%石粉18g和硫酸锌1.2g。同样护理,每星期对试验牛群进行修蹄及常规治疗。经过1个月的治疗第1组治愈1头,有效3头,无效5头;第2组治愈2头,有效6头,无效1头;第3组治愈3头,有效4头,无效2头;第4组治愈7头,有效2头,无效0头。卡方检测除第2、3两组差异不显著外,其他各组之间差异显著。说明在日粮中适量提高钙和锌对奶牛蹄病有良好的预防和治疗作用。     

土壤处理对西洋参根际线虫数量动态的影响及对防治茎线虫根腐病的效果

 Root rot of American ginseng (Panax quinquefolium) caused by Ditylenchus destructor is a novel disease found recently in Beijing area. The effects of three soil treatments (fumigating with chloropicrin, chloropicrin + lvfeng organic manure and nematicide fosthiazate) on the number of rhizospheric nematodes, survived plants, root yield and root rot of 3-year ginseng plant were compared. The effects were also investigated at the second year after treatment. The results indicated that the number of parasitic nematodes in rhizosphere of treated soil reached the peak value in late June to early July as the soil temperature raised in the growing season. Compared with the regular treatment, the number of plant parasitic nematodes was reduced while non-plant parasitic nematodes increased. The number of non-plant parasitic nematodes in the soil treated with chloropicrin + lvfeng organic manure was 2 times than that treated with chloropicrin only. The ratio of non-parasitic to parasitic nematodes of three treatments was higher than the control. Percent of survived plants was 94.8%-96.4% and diseased root was decreased obviously. The control efficacy was more than 89% at the first year after treatment. The survived plants and plot yield of ginseng increased significantly and the control efficacy was around 40% at the second year. The best of the three treatments was by chloropicrin + organic manure.     

一例副猪嗜血杆菌病的诊治

江苏进出口园林植物寄生线虫调查及检疫处理技术

1997－1998年，对南京口岸进口的荷兰、加拿大、美国、韩国、台湾和香港等国家和地区41批（次）园林植物检疫中，1次截获鳞球茎类线虫、19交截获咖啡短体线虫、草莓芽叶线虫、克鲁克剑线虫、毛刺尾线虫、南方根结线虫、花生根结线虫、北方根结线虫和其它根结线虫等，进口的园林植物中危险性疫情发生率高达34％。对江苏5个主要出口园林植物生长基地进行的植物寄生线虫种类调查，在59种经常性出口的园林植物中，发现27属植物寄生线虫，其中已鉴定出13种。对红花木莲苗上的南方根结线虫、牡丹苗上的腐烂茎线虫进行的检疫处理试验表明，用几种农药混配的处理液加热后处理植物的根部，可以有效地杀死这两种植物寄生线虫，保证货物安全出口。     

Applications of ionizing radiation for the control of postharvest diseases in fresh produce: recent advances

Postharvest diseases cause considerable losses to harvested fruits and vegetables worldwide. In addition to various treatments to control postharvest losses caused by pathogens, the global trend is shifting toward more ecofriendly alternatives safer to human health. Thus far, the main approach to postharvest disease control has mostly relied on the use of chemicals. However, the intense use of chemical fungicides has caused side effects such as environmental issues and evolution of fungicide‐resistant isolates. With increasing demand for the use of non‐chemicals, ionizing radiation has been investigated for application in many aspects of postharvest treatment, especially as an approach with significant potential for the control of postharvest disease. Recently, a number of more or less technologically advanced methodologies, e.g. irradiation combined with other types of treatments and induced disease‐resistance, have been developed to control postharvest diseases as well as to increase the quality and storage life of fresh commodities. Challenges for future application of irradiation in fresh produce are the cost, lack of irradiation facilities, lack of knowledge about optimal conditions for different commodities, and lack of acceptance of irradiated fresh produce. This review aims to document the advances in understanding of the effects of irradiation on postharvest disease, the possible modes of action, and the perspectives in commercial use.     

国医大师孙光荣论中西医学文化的比较

中西医学分属于不同的医疗体系,认识其差异,有利于寻求两者之间的共同点和交融的契合点,从而促进医学的发展。国医大师孙光荣通过系统的对比,得出两者之间在学科属性、医疗模式、诊疗思维、发展特点、治疗特点五个方面存在较大的差异。从学科属性而言,中医学具有自然科学与社会科学的双重属性,西医学则属于单纯的自然科学;从医疗模式而言,中医学为整体医学模式,西医学为生物医学模式或生物-心理-社会医学模式;从诊疗思维而言,中医学是包容性思维,主张非定点清除致病因子,西医学则是对抗性思维,主张定点清除致病因子;从发展特点而言,中西医学呈现出起点高、发展慢与起步晚、发展快两种截然相反的状态;从治疗特点而言,中医学以"观其脉证,知犯何逆,随证治之"与"中和"为特点,西医学则强调数据支持,临床路径、介入和干预。
