EFFECT OF HYALURONIDASE
THE PREVIOUSLY reported experiments on isolated pig and steer vitreous1 indicated that the decrease of viscosity due to autolytic processes enhanced diffusion of homologous hemoglobin in this substrate. No liquefying or depolymerizing effect of the enzyme hyaluronidase on hyaluronic acid—the viscous component of the vitreous jelly—could be demonstrated by the spreading rate of hemoglobin in fresh steer vitreous. However, these results could not be applied directly to conditions in the living eye of another species. In the first part of the present study the liquefying effect of hyaluronidase was examined on the vitreous of rabbit eyes in vivo. In the main experimental series the effect of the mycolytic enzyme on the disappearance of rat cells from the vitreous was investigated.
Washed red blood cells served as the test substance in rabbits. A sample of the animal's own blood was withdrawn from the heart or from
