  • Look Inside

 Studies of the biochemical changes associated with CJD and scrapie have had a long and chequered history, but there is still no firm information on the biochemical events underlying the pathogenesis of these diseases. In this article, recent advances of studies on nucleic acids, amino acids, proteins, lysosomal enzymes, lipids, neuronal membranes, and neurotransmitters in the brains of the patients and experimentally infected animals have been briefly reviewed.

 Main findings discussed are as follows: increased DNA synthesis in the affected animal brain after the inoculation of the agent, reduction of nuclear poly (A)-RNA level in scrapie brain, increased activities of various glycosidases in the brains of CJD patients and scrapie animals, change of ganglioside composition with severe reduction of the C 20-long chain base in the CJD patients, structural changes of affected neuronal membranes, and abnormalities of monoamine levels in the affected animal brains.
