Breakdown of the blood: aqueous barrier and prostaglandins.

The quantitative relationship between the degree of breakdown of the blood-aqueous barrier and aqueous humor prostaglandin content was studied in rabbits. After the primary aspiration of the aqueous, secondary aqueous humor was sampled. The samples were divided into two parts for the following measurements: one for the degree of the barrier breakdown which was represented by protein content determined by Lowry method and the other for prostaglandin content which was measured by radio-immunoassay. A significant linear relationship was obtained between the protein and prostaglandin E content but not between the protein and prostaglandin F content.
