  • THE HISTOGENESIS OF RETINOBLASTOMA: THE STUDIES OF IMMUNOHISTOCHEMISTRY,HISTOCHEMISTRY AND ELECTRON MICROSCOPY

    The studies of immunohistochemistry, histochemisu3r and electron microscopy in 50 patients with retinoblastoma were carried out. Our results show that retinoblastoma origin from primitive retinal neuronal cells that can differentiate into nmture neuron (including retinal photoreeeptor) and glial cells.The glial component in the retinoblastoma is mainly reactive glial proliferation.There is a good prognosis in the patients with retinoblastoma in which there are a lot of differiation areas and glial proliferation.

  • ENZYMATIC HISTOCHEMICAL STUDIES ON RETINAL VESSELS

    The activities and distributions of succinate dehydrogenase(SDH),malic dehydrogenase(MDH),lactic dehydrogenase(LDH),acid phosphatase(ACP) and alkaline phosphatase(AKP) in retinal vessels were studied and observed with enzymatic histochemical techniques. The retinal vessels showed a b LDH activity, moderate SDH and MDH activity. The dehydrogenase activity described above was evenly and equally distributed in the microvasculature between arterioles and venules, and was the best in arteries. AKP showed predominant activity in the endothelial cells of capillaries and arterioles which were stained bly. No activity for ACP observed in the retinal vessels. The observations above indicate that the retinal vessels are metabolically active and have a great capacity for glycolysis. (Chin J Ocul Fundus Dis,1992,8:6-9)
