Changes in dopamine concentration following hyposmotic shock in vivo and in cultured kidney cells.
(A) Dopamine concentration in the serum after freshwater shock of S. argus. Dopamine contration in the serum of SW-reared S. argus was set as the control group, and that of the FW-shock fish was regarded as the treatment group. (B) Dopamine concentration in the culture medium of S. argus renal primary cells exposed to hypoosmotic conditions (100 mOsmol/L) in *p < 0.05; **p < 0.01.
