Biological effects of microwave exposure have been studied.Some experi-mental results are as follows:1.The lethal dose of microwave radiation is 0.03 w.h./cm~2—0.05 w.h./cm~2in the rat.2.The threshold of acute biological microwave effect is 20 mw/cm~2 in therabbit.The microwave radiation causes a fall of blood pressure,accelerationof respiration and elevation of subcutaneous and rectal temperature.The ther-mal effects of microwave are very important in acute biological responses.3.The microwave radiation induces changes of Q-T interval,amplitude ofT wave of ECG and cardiac arrhythmia and ventricular fibrillation in some ani-mals.These results suggest the possible existance of nonthermal in addition tothermal effects.After animals were killed by microwave,bleeding in the lungs and conges-tion in the liver and brain were observed.But pathological changes were notfound in any parts of the body after a single sublethal dose of microwave radiation.

1.微波急性半数致死阈剂量为0.03瓦·小时/平方厘米—0.05瓦·小时/平方厘米(大鼠)。2.微波一次辐射的急性生物效应阈为20毫瓦/平方厘米(家兔)。它导致血压下降、呼吸加快、皮下温度和肛温上升。微波的致热作用在急性生物学效应中有重要意义。3.微波辐射可导致心电图 Q—T 值、K 值、T 波变化以及部分动物出现可逆或不可逆的心律失常。这些意味着微波除了致热作用外还有非热作用存在的可能性。4.微波急性辐射使动物致死后,发现肺脏有广泛性出血、肝脏郁血、脑组织充血、郁血等变化。微波急性一次辐射未致死动物的脏器未发现明显的病理变化。

An animal study was designed to determine whether the effective concentrations of GM. in bile and hepatic tissue could be influenced by different ways of injection. 6 normal dogs served as experimental animals and were divided into 2 groups. GM was injected via the portal vein in experimental group and by a peripheral vein in control group.In all animals, after injection, the GM levels in bile, serum and hepatic tissue were measured. The results showed that the former route of GM injection was not only safer...

An animal study was designed to determine whether the effective concentrations of GM. in bile and hepatic tissue could be influenced by different ways of injection. 6 normal dogs served as experimental animals and were divided into 2 groups. GM was injected via the portal vein in experimental group and by a peripheral vein in control group.In all animals, after injection, the GM levels in bile, serum and hepatic tissue were measured. The results showed that the former route of GM injection was not only safer but also more significantly increased the GM levels in bile and liver as well as the biological responses in blood than the latter route. There were no toxic responses and no hepatic damage in either group. We believe that GM delivered via the portal vein for treatment in biliary tract infections would be better than that via a peripheral vein.

An overview of the application of structure activity relationships(SARs) in environmental chemistry is presented.The environmental behaviour of organic pollutants depends on their chemical structure described by various physicochemical parameters, among which lipophility is the predominant one. In most cases the part of the free energe change which can be attributed to the hydrophobic bonding usually gives the major contribution to the biological response compared with the other factors. In the SARs study lipophility of organic compounds is measured by their partition coefficients, P, in the n-octanol/water system.The environmental behaviours, such as solubility, toxicity, the tendencies of sediment adsorption and bioaccumulation, of organic pollutants are strongly related with their log P values.The dissociation constants of organic acids and bases also strongly influence their environmental behaviours through the pH variation of ambient water. These physicochemical parameters of organic pollutants are therefore useful in the forecasting of potential hazards caused by these pollutants.Such forecasting may help us to focus further studies on more important subjects.The calculation of log P by Hansch's hydrophobic substituent constant and Rekker's hydrophobic fragmental constant, the determination of log P by traditional direct shake-flask methods and indirect chromatographic methods are discussed.The determination of acid constants, Kα, and the simultaneous determination of Kα and log P are introduced by using chlorophenols as examples.

本文讨论了有机污染物的环境行为,如溶解度、毒性、生物体内富集趋势,在沉积物表面上的吸附趋势,生化降解性等与其物化性质的关系。由分子结构所决定的这些物化性质中影响最大的是亲脂性,通常用化合物在正辛醇-水系中的分配系数log P量度。对于可离解的有机酸、有机碱,其离解常数K_a、K_b通过环境水域pH的变化亦强烈地影响化合物的环境行为。对计算法求1ogP值,直接摇瓶法及间接色谱法测logP值进行了讨论。以酚类为例介绍了有机酸离解常数pK_a的测定方法,logP及pK_a的同时测定方法。
