[Pathomorphological changes of the macroglia in chronic intoxication produced by gas containing hydrogen sulfide]. / Patomorfologicheskie izmeneniia makroglii pri khronicheskoi intoksikatsii serovodorodsoderzhashchim gazom.

Changes in the rat brain macroglia produced by a natural gas from Astrakhan source containing hydrogen sulphide were studied immunocytochemically (glial fibrillar acid protein). Primary response was from oligodendroglia, dose increase followed by reaction from the astroglia.

Measurement of enzymes in environmental intoxications.

The paper details the enzymes which have been shown to be affected by certain zenobiotics, principally industrial pollutants, toxic metals, toxic gases and food additives. The role of mixed function oxidases is discussed and methods of assessing their activity indicated.
