Figure 1: Inhibitory effect of various doses (0.001 nM–100 nM) of T3 on synaptosomal Na+-K+-ATPase or Mg2+-ATPase activity, in vitro. The data are represented as mean ± SEM of ten separate experiments, taking six animals in each group. The vertical lines denote SEM. Filled circles indicate Na+-K+-ATPase while filled triangles indicate Mg2+-ATPase activity.
