On the Distribution of the Adrenal Gland in Toadfish Kidney

Abstract

A histological investigation was done on the distribution of the adrenal gland in the kidney tissue of the toadfish, Opsanus tau, a famous aglomerular teleost. The giand was detected in the wall of postcardinal vein penetrating peripherally in the anterior half portion of both left and right kidneys. The glandular tissue was composed of intermingled interrenal and chromaffin cells. Furthermore, occasionally cell cluster consisting of both kinds of the cells was observed also in the renal interstitial tissue in the vicinity of the postcardinal vein. © 1980, The Japanese Society of Fisheries Science.
