Comparative effects of atropine sulfate (blue, green) injection at 12:00 hours on estradiol serum levels (pg/ml) to rats with bilateral perforation of the peritoneum (purple) or bilateral ovariectomy (yellow) performed at 13:00 of diestrus 1 (D1), diestrus 2 (D2) or proestrus (P) sacrificed one hour after surgery. * p < 0.05 vs. bilateral perforation of the peritoneum (Student's t test); ** p < 0.05 vs. bilateral ovariectomy (Student's t test).
