摘要：

Turnover measurements were made in canine eyes following direct microinjection and mixture of 1μl to 2μl amounts of serum albumin, iodohippurate, and iodoantipyrene into the anterior chamber (each labeled with iodine 125). Complexity of the procedure was considerably reduced by use of an anterior chamber control cannula for injections and a small scintillation probe for external monitoring. The normal turnover of serum albumin (1.85%/min) was inhibited 75.29% by acetazolamide. lodohippurate and iodoantipyrene cleared at rates of 2.99%/min and 3.85%/min respectively, and each was less inhibited by acetazolamide than was serum albumin. Both hyperoxia and serum uveitis caused significant inhibition of iodohippurate and iodoantipyrene clearances. Significance of the method for studies in uveal physiology is discussed. © 1969, American Medical Association. All rights reserved.
