Fig. 2. Effects of tamoxifen on the attenuation of 5-HT-induced arterial contraction by E2.
a A representative tracing of the CRC of arterial contraction by cumulative application of 5-HT under control conditions. b A representative tracing of the CRC of arterial contraction by cumulative application of 5-HT in the presence of tamoxifen (10 μM). c A representative tracing of the CRC of arterial contraction by cumulative application of 5-HT in the presence of tamoxifen (TAM, 10 μM) and E2 (100 μM). d Summary of the CRC of 5-HT-induced arterial contraction in the absence and presence of tamoxifen (10 μM) or tamoxifen (10 μM) plus E2 (100 μM). The number in parenthesis (n) indicates the number of animals examined. ***p < 0.001 vs control
