Fig. 8From: β adrenergic receptor/cAMP/PKA signaling contributes to the intracellular Ca2+ release by tentacle extract from the jellyfish Cyanea capillata In vivo effects of propranolol on the TE-induced declination of blood pressure (BP). Propranolol at 0.75 mg/kg was pre-administrated, followed by 0.5 mg/kg TE through the external jugular vein in intact rats. The representative images (a) and parameters (b) of BP were displayed.
