Figure 7: Influence of DB cAMP and T3 on synaptosomal Na+-K+-ATPase activity, in vitro. (a) Inhibitory effect of various doses of DB cAMP on synaptosomal Na+-K+-ATPase activity, in vitro. The data are represented as mean ± SEM of four separate experiments, taking six animals in each group. The vertical bars denote SEM. (b) Interaction of the effects of of DB cAMP and T3 on synaptosomal Na+-K+-ATPase activity, in vitro. Filled squares indicate effects of graded doses of T3 (0.001 nM–10 nM) alone on Na+-K+-ATPase activity while filled triangles indicate effects of the 0.2 mM dose of DB cAMP with graded doses of T3 (0.1 pM–1 μM).
