The preparat ion of a specific antiserum (anti-CaBP) against the calcium-binding protein (CaBP) of the chorioaUantoic membrane ( C A M ) is described. The antiC a B P appeared to be specific for the C a B P by immunodiffusion and immunoelectrophoresis. Applicat ion of the ant i -CaBP in immunofluorescence histochemistry revealed that the C a B P is present in the C A M only at developmental age...

INTRODUCTION Pterygium represents a triangular conjunctivo-epithelial overgrowth, proliferating from the bulbar conjunctiva and covering the cornea, causing severe vision loss. It is an abnormal growth and differentiation of the conjunctive epithelial structures of the corneal limbus. Chronic exposures to solar ultraviolet radiation, heat and dust, as well as viral agents, are the most common p...
