摘要
1997年,作者发表了“中国大骨节病防治策略”,尔后课题组一直在寻找新的数据、情况和事实,以检验提出的“策略”是否经得起时间的考验,然而并没有发现相反的例证。鉴于这个问题的重要意义,特别是已经纳入正在实行的国家防病规划,作者以为有必要用若干数据尤其是新的数据,对其作进一步诠释。新的数据主要是近年来关于粮食中T鄄2毒素含量的若干补充材料,引人注目的是这些数据在本质上和1994年作者们所发表数据的一致。如此乃深化了我们对策略的整体性和一贯性的理解。病区的土壤以及自然条件有利于有毒镰刀菌的生长,地产粮食成为盛纳和传播真菌及其毒素的载体。小麦和玉米传病,大米不传,不卫生的收割、储藏和制粉条件是影响毒素的产生及其含量的重要因素。病因流行病学的基本事实,作为构成“防治策略”的基础,是由T鄄2毒素贯穿起来的一个系统的过程。一切都是为了能够因地制宜地将粮食中的T鄄2毒素降低到容许浓度以下。"防治策略"解决了有根据地实现了因地制宜地控制大骨节病,直到消灭病区的久远理想。
In 1997, the author published a paper “Study on Chinese strategy for Kacshin-Beck disease control”, there after our research group began to collect relative new data, information and facts to verify a consideratiQn whether the “strategy” can be with stand temporal try, bnt no opposition exemplification had been found out yet. Because of the importance of this problem and because of the “strategy” had adopted by govenlment and incorporated into the disease control program for west region of our country, the author think it is a need to explain more deeply on this problem with some new data. The new data mainly is the results of chemical analysis for T-2 toxin in cereal samples and in which a fact, catch our eye, is the new data significantly in consistence with the data published by us in 1994. This fact, therefore, deepened our understanding about the entirety and persistence of the “strategy”. The natural condition and soil in KBD endemic area are suitable for the growth of toxic Fusarium and the cereals produced in sick local become the media and cartier for the propagation and toxin production of these fungus. In the KBD endemic area the ability to propagate the disease for different cereals is in vary different extent, the wheat and maize is strange but rice does have this effect at all. The harvestry, storage and milling of cereals in no sanitation conditions, are the promoting factors for the production and accumulation of T-2 toxin in cereals. The theory basis of the strategy is the causes epidemiology and the basic fact is the propagation mechanism of T-2 toxin in nature circumstance and life style of the people in local area, therefore the strategy is a systematic protocol, and the core point is to decrease the T-2 contents in cereals to a safety level,according to the local conditions. Of this “strategy”, based on a right foundation, the problems about KBD control were resorted well and by this program the disease and the sick area can be vanished at all.
