Lactate dehydrogenase composition of the rabbit retina and choroid after ischemia caused by ligature of the optic nerve

, : Lactate dehydrogenase composition of the rabbit retina and choroid after ischemia caused by ligature of the optic nerve. Ophthalmic Research 9(3): 201-204

LDH [lactate dehydrogenase] isoenzymes of rabbit intraocular tissues were separated by thin-layer isoelectric focusing and localized as discrete groups of multiple bands detected by tetrazolium staining. In the rabbit intraocular tissues the predominant isoenzymes were LDH 3, 4 and 5. The bands showed microheterogeneity and were composed of 2-6 subcomponents. After 2 days of ischemia the LDH isoenzymes showed a considerable increase of activity in retina, choroid and iris. The appearance of LDH subcomponents in choroid and iris, and the disappearance of these components in cornea after ischemia was observed.

An increase in Rho kinase (ROCK) activity is implicated in chronic hypoxia-induced pulmonary hypertension. In the present study, we determined the role of ROCKs in cGMP-dependent protein kinase (PKG)-mediated pulmonary vasodilation of fetal lambs...
