1. It is also called "antagonism". The phenomenon that the effect of a substance is suppressed by another substance. For example, in tea culture medium, aluminum has antagonistic effect on manganese. The inhibition of the metabolites and the effect of one physiological process on the other physiological processes also belong to this category. For example, fatty acids in tea plants can react with glycerol to produce fat, and can also be reduced to fatty aldehydes or fatty alcohols. If the conditions of synthetic fat are greater than the conditions of reduction, they will accelerate the synthesis of fat.
2. A phenomenon of antagonism between muscles, drugs, or physiological processes. For example, the effects of insulin and glucagon on blood glucose level, the effect of parathyroid hormone and calcitonin on bone absorption, the function of extensor and flexor muscle, and the effect of vasodilator and vasoconstrictor.
3. The mutual antagonism of different reflex activities in the body. Such as flexor and extensor reflex, swallowing reflex and inhalation reflex, etc. They are antagonistic to each other. When the extensor reflex is carried out, the reflex of the flexor muscle is bound to be inhibited. Similarly, swallowing reflex and inspiratory reflex can not be carried out at the same time, one excitement and the other one is bound to inhibit. This is due to the establishment of a fixed antagonistic antagonistic relationship between the central parts of the reflex arcs.
The coexistence of the 4 and two kinds of antagonism. The antagonism between microbes or drugs. The inhibition of another microorganism, such as a microorganism, by metabolic competition, and other reasons. If two or two kinds of drugs are used simultaneously, the drug utility is weakened or disappeared. The antagonism of antibacterials can be determined by broth or agar chessboard dilution, and the inhibitory concentration index is more than 2. Insulin and glucagon are also a case of antagonism.

Antagonistic action, that is, some elements inhibit the absorption of other elements by crops. It means that different hormones play an opposite role to a physiological effect, such as lactic acid in pickles, inhibit the growth of bacteria.
1. Antagonism refers to the opposite effect of different hormones on a certain physiological effect.
2, this can be explained by the regulation of insulin and glucagon on blood sugar content.
Glucagon is secreted by the islet A cells. Its main role is to promote glycogen decomposition and the conversion of non sugar substances into glucose, thereby increasing blood sugar. When the blood glucose level is high, insulin secretion is increased, glucagon secretion is reduced. The result of two kinds of hormones citrus resistance is to promote blood glucose synthesis into glycogen, and inhibit the conversion of non sugar substances to glucose, and decrease the content of blood sugar. When blood sugar level is low, insulin secretion is reduced, glucagon secretion is increased, the result is to promote glycogen decomposition into glucose, and promote the conversion of non sugar substances to glucose, and increase the blood sugar level. It can be seen that the hypoglycemic effect of insulin and glucagon's hypoglycemic action are mutually antagonistic, which can regulate glucose metabolism and maintain blood glucose level at a relatively stable level.
3, the antagonism of insulin and adrenaline.

1, drugs refers to drugs and the body caused by the interaction of drug reaction, namely contact or into the body, promote the change of physiological and biochemical functions of surface and internal environment, or inhibition of invading pathogens, helping the body to improve disease resistance to disease prevention effect called drugs. Specifically, when each factor is combined, one factor can inhibit or affect another factor to play a role. As in pickles, lactic acid inhibits the growth of bacteria.
2. At the same time, the drug is also affected by the body. The process of changing the drug in the body is called the metabolism of the drug. As a result, drug action and drug metabolism are two aspects of the interaction between the drug and the body. In vivo, the role of drugs gradually strengthened, and then gradually weakened or disappeared. That is, the influence of the body on the drug shows various changes, so that the original function of the drug is lost and discharged.
The effect of the combination of 3 and two drugs is less than the sum of their effects. Antagonism: the toxicity of the combined action, less than the sum of the toxicity of the components of the toxic substances alone. That is to say, one toxicant component can accelerate the degradation of other toxicants, accelerate and accelerate excretion, reduce absorption or produce low toxic metabolites, and reduce the toxicity of mixtures.
