_D_e_s_c_r_i_p_t_i_o_n:

     Five rabbits were studied on two occasions, after treatment with
     saline (control) and after treatment with the 5-HT_3 antagonist
     MDL 72222.  After each treatment ascending doses of
     phenylbiguanide were injected intravenously at 10 minute intervals
     and the responses of mean blood pressure measured.  The goal was
     to test whether the cardiogenic chemoreflex elicited by
     phenylbiguanide depends on the activation of 5-HT_3 receptors.
