The purpose of the present study is to ascertain the changes in localization of

(35)

S-methionine in brain in the process of acupuncture analgesia by means of macroautoradiographic and microautoradiographic methods.The results show that

when the rats were subjected to electro-acupuncture analgesia

the ma- croautoradiographic intensities of (35)S-methionine in brain in the process of acupuncture analgesia by means of macroautoradiographic and microautoradiographic methods.The results show that

when the rats were subjected to electro-acupuncture analgesia

the ma- croautoradiographic intensities of

(35)

S-methionine in gray matter of cortex and thalamus were significanty increased

as well as the microautoradiographic intensities in gray matter of cortex

mesencephalon aaueduct and periaqueductal gray matter were also markedly elevated

From this it can be concluded that (35)S-methionine in gray matter of cortex and thalamus were significanty increased

as well as the microautoradiographic intensities in gray matter of cortex

mesencephalon aaueduct and periaqueductal gray matter were also markedly elevated

From this it can be concluded that

(35)

S-methionine in brain undergo profound depressive changes in the process of acupuncture analgesia.
