Factors regulating the functioning of the in vitro perfused aglomerular kidney of the anglerfish, Lophius piscatorius L.

Kidneys sans glomeruli

“…The youngest lineage of aglomerular fish, the percomorphs, evolved only 23 million years ago, long after apes, monkeys, and whales had appeared. Percomophs include the aglomerular seahorse, pipefish, dragonet, sea poacher, scorpion fish, rock fish, puffer fish, porcupine fish, clingfish, and some notothenioid antarctic fish (8,44,84). However, most of the 10,000 species of percomorphs have glomerular kidneys; among them are the seabass, halibut, tuna, flounder, and the coral reef fish.…”

Endocrine Control of Renal Handling of Solutes and Water in Vertebrates

“…However, these changes may be simply the results of a reduction in systemic blood pressure or vascular tone resulting from adrenocortical insufficiency. The renal output of Na decreased after an injection of D O C A or hydrocortisone into the conscious, chronically cannulated rain bow trout [66], whereas cortisol adminis tered directly into the renal portal system supplying the renal tubules of the aglomerular angler fish did not alter urine flow or urinary electrolyte concentration [3]. In con trast.…”

“…A V T did not increase the osmotic water per meability of the diluting segment [89] or the water or Na transport in the isolated urinary bladder [74], which is embryologically equivalent to the collecting duct. A V T or isotocin administered to the aglomerular toadfish [124] or to the aglomerular angler fish [3] produced either no effect or only a slight increase in urine flow.…”
