[Reduction, by atropine, of symptomatic shock induced by PGF2 alpha in the dog].

Two groups of 5 bitches different in breed, age and size were given a single dose of PGF2 alpha at a dosage of 0.25 and 0.50 mg/kg of body weight respectively. Since the administration of PGF2 alpha is usually associated with a syntomatic shock in the bitch, four bitches per group were additionally treated with a single dose of atropine (0.050 mg/kg). Two of the four bitches were injected with atropina I.M. contemporaneously with the PGF2 alpha and the other two at the beginning of the symptomatology. Both the former and the latter show a marked reduction of symptomatic shock. The AA. discuss the possible use of PGF2 alpha associated to the administration of atropine in the current therapy of some reproductive disorders of the bitch.
