Gaafar, K., A. R. laila khalek, N. K.El-Sayed, and S. H. Karam, "Histoenzyme changes in chronic methyl alcohol retinotoxicity in rats", the egyptian journal of histology, vol. 14, pp. 377-384, 1991. Abstracthistoenzyme_changes.pdf

Male albino rats were administered methyl alcohol in their drinking water as 2,4 ad 6% solutions for four weeks. Methyl alcohol concentration was determind in the sera of rats after 1,2 and 4 weeks and was found too increase significantly.

Retinal tissue was removed at similar time intervals for histopathologic and histoenzymologic examination. The retinal damage was directed at the photoreceptors primarily and the neuronal elements. A significant finding was the loss of outer layers of the retina after prolonged methyl alcohol intake. Succinic dehydrogenase (SDH) increased and NAD-linked lactate dehydrogenase (LDH) decreased indicating enhanced aerobic glycolysis and depressed anaerobic glycolysis. Acid phosphatase (ACP), alkaline phosphatase (ALP) and adenosine triphosphatase (ATPase) activities were notably increased in the pigment epithelium, choroid and sites of enzyme activities in the retina. The increase in ALP and ATPase in the pigment epithelium may be attributable to the increased demands of the retina for metabolic exchange and reflect modified membrane permeability induced by the toxin.
