Enzymic studies on sulphatide metabolism in different stages of experimental allergic encephalomyelitis

The activities of three enzymes-cerebroside sulphotransferase, 3'-phospho-adenosine 5'-phosphosulphate synthesizing enzyme and arylsulphatases A and B have been studied in various developmental and recovery stages of experimental allergic encephalomyelitis. The concentrations of cerebroside and sulphatide were also analysed during these stages. It was observed that the sulphatide concentration decreased during the development of the disease, with a concurrent increase in the activity of arylsulphatase and vice versa during the recovery stages. 3'-Phosphoadenosine 5'-phosphosulphate synthesis as well as sulphotransferase activity increased during the pre-acute stage of the disease, reached a maximum at the acute stage and decreased during recovery stages
