Hypophysectomy of freshwater-adapted eels resulted in a marked reduction in net absorption of PO4(3-) in the non-stripped and non-everted intestine. Stanniectomy was without effect on net movements of water and electrolytes in this isolated eel preparation. Repeated injections of eel calcitonin into the eel, kept either in deionized water or 10 mM CaCl2, had no effect on net absorption of water and electrolytes, including Ca2+ and PO4(3-). In the stripped and everted intestine, the net PO4(3-) absorption was significantly greater in the fed eel than in the starved fish. Hypophysectomy of the fed eel resulted in a significant reduction, not only in PO4(3-) absorption, but also in absorption of water and other electrolytes. It is suggested that pituitary hormone is involved in the intestinal PO4(3-) absorption of the eel.
对适应淡水的鳗鱼进行垂体切除后,未剥离且未翻转的肠道中PO4(3-)的净吸收显著减少。在这种分离的鳗鱼制剂中,切除鳔对水和电解质的净移动没有影响。将鳗鱼降钙素反复注射到置于去离子水或10 mM氯化钙中的鳗鱼体内,对包括Ca2+和PO4(3-)在内的水和电解质的净吸收没有影响。在剥离且翻转的肠道中,喂食的鳗鱼的PO4(3-)净吸收显著高于饥饿的鱼。对喂食的鳗鱼进行垂体切除不仅导致PO4(3-)吸收显著减少,还导致水和其他电解质的吸收减少。提示垂体激素参与鳗鱼肠道对PO4(3-)的吸收。
