 Clinical: Male patient of 42 years of age, who had been in contact with carbon disulfide gas 11.5 ppm on an average for 21 years and a half, revealed hypertension at the age of 37. In the course of the illness, sensory and motor disturbances, loss of memory, incontinence, dysarthria, forced laughing, disturbance of intelligence and charac ter, pyramidal sign, rigidity, pseudo bulbare symptoms, lethargy, disturbance of coordination, nystagmus and primitive reflex wereexhibited. Physical examination disclosed abnormal EEG, arteriosclerosis of fundus oculi and proteinuria.

 Histopathological: In the first, marked atherom-sclerosis were observed in all of arteriesand small arteries of the brain and spinal cord. In the arteries of central nervous tissue, fibrinoid degeneration was remarkable, and in partially calcium oxide precipitated to the wall and peri vascular infiltration were observed. In the second, the foci of encephalomalacia were observed in thalamus, pallidum, caudatum central semiovale, cerebellare white matter and putamen,

 These foci had a tendency to extend symmetry on both sides of the brain. In generally, reactions of glia cell and gitter cell were not so remarkable and not accompanied by haemorrhagic lesion. The degenerating changes were observed in pyramidal, spinocerebellar and spinothalamic tracts.

 The loss of many or a little nerve cells were observed in the cerebral cortex.

 The changes of arteriosclerosis were also observed in other arteries such as kidney, heart and spleen.
