茶树六种重要钻蛀性害虫形态及为害的记述

1953年至1957年,作者在福建省福安县城关、坦洋、社口,福鼎县白琳,崇安县赤石等主要茶区对茶树害虫种类及发生情况作了初步的调查,在工作进行中,发现除了茶毛虫等重要食叶性害虫外,数种钻蛀性害虫也已成为茶叶生产上重要的威胁因素,为此,曾着重地进行了调查研究。它们的名称是:茶枝蛀蛾(Casmara patrona Meyrick)、茶梢蛀蛾(Parametriotes theae Kus.)、茶堆砂蛀蛾(Linoclostis gonatias Meyrick)、茶天牛(Aeo-lesthes induta Newman)、茶红颈天牛(Chreonoma atritarsis Pic)、茶吉丁虫(Agrilussp.)。

短翅树莺的繁殖习性

短翅树莺是森林益鸟。本文着重记述了其种群的分布和数量及迁徙动态,并对其歌唱声和惊叫声作了录音分析及文字描述。文内较全面地记述了繁殖习性和食性。并对其繁殖力和雏鸟(257只)生长曲线方程作了较深入的探讨。     

甜茶蛋白质成分的研究

对甜茶的蛋白质和氨基酸进行了试验,从甜茶水解产物中检出了18种氨基酸,其中8种为必需氨基酸。     

A REVIEW OF THE LITERATURE ON THE ETIOLOGY OF HODGKIN'S DISEASE

Extensive research to trace the cause of Hodgkin''s disease to a bacterial or protozoan agent has proven fruitless.Although a viral cause for Hodgkin''s disease has been previously suggested, early explorations along that line have not been confirmed. With the development of newer techniques for the study of viral characteristics certain apparently significant factors in Hodgkin''s disease have been encountered. Most promising has been the consistent demonstration that Seitz-filtered, sterile Hodgkin''s disease lymph node extract can be passed serially in fertile chicken eggs and that the amniotic fluid from these eggs possesses the capacity to interfere with the growth of influenza virus in eggs.     

THE MEANING OF DISEASE

A wider concept of disease is developing, which deals with the social environment, not only with the physical, chemical or ecological factors, as they affect the homeostasis of the internal environment of the organism. In such a concept it is the fitness of the whole personality which determines ease or dis-ease in adaptation. If the medical profession is to retain the strategic direction as well as the tactical command of the battle for health, it must widen the bases of its educational program so that every physician will understand and conform to the plan of battle even though his individual role is highly restricted; so that even in the office of a technical specialist the whole personality of the patient in relation to his whole environment is dealt with.     

绿茶抗氧化剂成分抑制突变作用的初步研究

绿茶水溶性提取物及茶叶中抗氧化剂成份具有明显的抑制AFB_1及Bap诱导的鼠伤寒沙门氏菌回复突变作用。这种抗氧化剂成份还可以抑制AFB_1和Bap诱导的V79细胞基因正向突变,以及AFB_1诱导的V79细胞SCE和染色体畸变。本实验结果提示,绿茶中抗氧化剂成份可能对AFB_1及Bap的致癌性具有抑制作用。本文就茶叶抗氧化剂抑制突变的可能机制进行了初步讨论。
