Glomeruli were preincubated with 1 μM angiotensin II (Ang II) for 5 min. Incubation was continued with various concentrations of nucleotides: ATP (•), ADP (^), 100 μM AMP (▴), UTP (▴), 0.01 μM 2-MeSATP (□), 100 μM β,γ-meATP (▪) or 10 μM adenosine (⋄) for 2 min. Results are expressed as a percentage of basal value. Data points are means ±s.e.m. (n = 6-8); *P < 0.05 nucleotides + Ang II vs. ineffective dose of nucleotides.
