Figure 2. Time-dependent effect of orchidectomy on the release of TXA₂ from rat aorta and mesenteric artery.

The plots present the basal- and ACh-induced TXA₂ release in aorta (A) and mesenteric (B) segments from control, 6 weeks and 5 months post-orchidectomized rats. Results (mean ± SEM) are expressed as pg/mL/mg tissue. Number of animals: 4–7. * p<0.05, ** p<0.001 compared with its respective basal condition; # p<0.01 compared with basal TXA₂ release in control animals; + p<0.01 compared with ACh-induced TXA₂ release in control animals. The number of animals used were: control, 6; 6 week post-orchidectomy, 4; 5 months post-orchidectomy, 7.
