[Experimental model of histamine-induced anaphylactoid reaction on beagle dogs].

To establish animal model of histamine-induced anaphylactoid reactions on Beagle dogs through intravenous injection of histamine phosphate injection. Anaphylactoid reactions was determined according to the changes of praxiology and blood pressure of Beagle dogs after one intravenous injection of histamine phosphate injection. It showed that typical anaphylactoid reactions be caused by histamine phosphate injection on Beagle dogs, and the response of the high-dose group was more obvious than that of the low-dose group. Intravenous injection of histamine phosphate injection could simulate Beagle dogs to bring typical clinical anaphylactoid reaction, that could be used as a sensitive animal model to evaluate anaphylactoid reaction of traditional Chinese medicine injections (TCMIs) in the pre-clinical experiments of both TCMIs and their composition.
