Figure 1. Time-dependent relaxing effect of ATP on Ang II-precontracted glomeruli.
Glomeruli were preincubated with 1 μM angiotensin II (Ang II) for 5 min. Incubation was continued with (•) or without (^) 1 μM ATP for the indicated time. Results are expressed as mean values of GIS (pl per glomerulus). Data points are means ±s.e.m. (n = 7%); *P < 0.05 ATP + Ang II vs. Ang II alone (control).
