The main attention has been paid to ascertain the moments, when the first signs of differences appear in the previously homogenous cellular material of the differentiating mesenchyme around the ocular cup and in the eyelids, taking into account appearance of derivates in the ocular auxiliary apparatus: sclera, oculomotor muscles, stroma of the lacrimal gland, cartilagenous laminae in the eyelids and in the orbicular muscle. Regularities of cytochemical differentiation of the mesenchyme and its derivatives have been studied, taking into account the organ's changing topography. Morphometrical investigations of cells in the anlages mentioned are expanded and correlated with the time of their cytochemical differentiation.

There is a close correlation between the process of Wallerian degeneration and aseptic inflammation. In the area of decay of the myelinated nervous fibers 4 types of cells have been identified and characterized. Three of them are precursors of macrophages, participating in removal of the myelin decay products: mononuclear cells of hematogenic origin, perineural cells, endoneural fibroblasts. The dynamics of these cells transformation into macrophages and into \"foam cells\" has been followed. The fourth type--Schwann cells; they do not directly participate in removal of the myelin decay products. They do not die, but, separating from the segments of the disintegrated myelin, dedifferentiate, proliferate and form cords, into which regenerating axons then grow in.
