One hundred and twenty samples of haemorrhagic spinal fluid were examined by acid phosphatase staining. This enzyme activity starts to appear in mono-histiocytic cells 2 days after bleeding and increases up to the 5th day. After 1 week the activity decreases rapidly. Similar results are found in mixtures of incubated clear spinal fluid, to which blood is added. Acid phosphatase staining is a useful additional method for determination of the age of a leptomeningeal bleed.

Of four patients with palatal myoclonus, three had infarcts resulting from atherosclerosis, and one had cerebral emboli from a left atrial myxoma. Three specimens showed lesions in the brainstem and bilateral hypertrophy of the inferior olivary nuclei; the fourth revealed unilateral olivary changes caused by an infarct in the contralateral dentate nucleus. After incubation for acetylcholinesterase, neuropilar and capillary wall staining were absent or much reduced, but there was increased denisty of reaction product in the neuronal cell bodies and in numerous tortuous dendrites. Methods for acid phosphatase showed strong activity in the dendrites and glomeruloid structures of the diseased olives. Reactions for nonspecific esterase indicated dendritic expansion and reduced staining density in nerve cell bodies, but augmented glial reactivity.
