Anaphylaxis is one of the most common and harmful of all adverse effects of drugs. It has no direct relation to the toxicity and dosage of drugs, but belongs to the pathologic immune reaction, directly threatening patients' lives. At present, many important advances and breakthroughs have been achieved in the researches on drug anaphylaxis of the penis, but many researchers have gone hardly any further than reporting the symptoms and treatments of a few individual cases, but very few specific substantial researches on penis drug anaphylaxis.

Because of the rapid action and high bioavailability, traditional Chinese medicine injections (TCMIs) had been widely used in clinical critical field. In recent years, with the increasing reports of clinical adverse reaction, more and more attention was paid to them, and acute allergic reaction was the main adverse reaction. Acute allergic reaction included type-I anaphylaxis reaction and anaphylactoid reaction, the latter had been found in a variety of TCMIs and accounted for 77% of adverse reaction. But the mechanism of anaphylactoid reaction was not completely understood, the standard animal model for TCMIs was not established, and the technical guidance for anaphylactoid reaction was not formulated. Thus the three aspects included mechanism, evaluation index and evaluation methods of TCMIs for anaphylactoid were reviewed. Five ways including direct stimulating pathway, complement pathway, coagulation pathway, kallikrein-kinin pathway and acute allergic pathway were the main mechanism of anaphylactoid reaction; whole animal model and cell model were the main evaluation methods; the occurrence index and effect index were reviewed for the evaluation index analysis.

OBJECTIVETo evaluate the sensitization effect of polysorbate 80 and polysorbate 80 contained Houttuynia cordata Injection in different concentrations on Beagle.

METHODSBeagles, a kind of animal highly sensitive to sensitizing agents, were randomly divided into 18 groups, 3 in each group. They received respectively the intravenous infusion of polysorbate 80 made by different factories in different concentrations (0.25%, 0.10%, 0.05%), and Houttuynia cordata Injection containing polysorbate 80 in concentration of 0.25% or 0.30%, with the constant infusing speed of 5 mL/min and volume of 10 mL/kg. Changes of animals' condition were observed before infusion and in the 24 h after infusion, time of symptom appearance and disappearance was recorded, and the grade of response was determined. Moreover, blood samples of animals were collected before infusion and 10 min after ending infusion for measuring histamine content in plasma using ELISA. Then the sensitization effect was comprehensively estimated by combined consideration of the responding grade and histamine level.

RESULTSNo typical symptom of anaphylactoid reaction and over 1-fold increase of histamine level was found in all groups that received intravenous infusion of polysorbate 80 or polysorbate 80 contained Houttuynia cordata Injection in different concentrations. Estimation showed that all test solutions didn't induce typical anaphylactoid reaction on Beagle.

CONCLUSIONSConsidering both the appearance of symptoms and the elevation of blood content of histamine could be taken as the criteria for comprehensive diagnosis of anaphylactoid reactions. The solubilization effect and safety (for foreclose anaphylactoid reaction) of polysorbate 80 could be ensured by controlling its quality and concentration below 0.25% or 0.30%.

OBJECTIVETo investigate the safety of different level of tween 80 by comparing the degree of pseudoanaphylactoid reactions (PR) induced by medicinal tween 80 and injectable tween 80.

METHODThe analysis of vascular permeability of the mice ears: ICR mouse were divided into different test groups, the mice were intravenously injected with solutions of medicinal tween 80 and injectable tween 80 with 0.2%, 1% and 5% concentration, positive control Compound 48/80 and 5% glucose injection. All test substances were mixed with 0.4% Evans blue. The reaction and vascular permeability of the ears were observed and measured 30 min after injection. The analysis of vascular permeability of the rat's skin: the rats were intravenous injected with 0. 6% Evans blue normal saline solution first, 10 minutes later, the same substances were intradermal administrated into the back of rats. The rats were sacrificed and the diameter of locus ceruleus and the content of Evans blue leak out were measured 20 min after injection.

RESULTMedicinal tween 80 and injectable tween 80 with 5% concentration caused obvious vascular hyper permeability in ICR mice, but the degree of vascular hyperpermeability caused by injectable tween 80 was lighter than by medicinal tween 80. Other tween 80 didn't cause obvious vascular hyper permeability in the ears of mouse. The solution of different concentration of tween 80 caused obvious locus ceruleus reaction in rat's back. As for the content Evans blue leak out, there was no statistical significance between each group except positive control Compound 48/80 group.

CONCLUSIONTween 80 can cause obvious vascular hyper permeability and the effect is dose dependent, which indicated that tween 80 can cause PR. On the other hand, injectable tween 80 is more security than medicinal tween 80, the dosage of tween 80 should be still controlled strictly so that to decrease the incidence of PR.

OBJECTIVETo compare the anaphylactoid effect of old Shengmai injection and new Shengmai injection on Cynomolgus monkey.

METHODCynomolgus monkeys were randomly divided into 4 groups, and were respectively injected with 5% glucose injection, old Shengmai injection, new Shengmai injection, positive control drug. The changes of each monkey were observed from injection before until 24 hours after injection, and the response level was determined according to the severity of the symptoms. Blood samples were collected before injection and at 10 min after injection for measuring histamine content in plasma. Blood pressure and heart rates were detected before injection and at 10 min after injection. Sensitization of the injection was comprehensively determined by combined the response level of symptoms and the histamine level.

RESULTThe Cynomolgus monkeys administrated with old Shengmai injection showed typical symptoms of anaphylactoid reactions and the content of serum histamine is not more than doubled. The Cynomolgus monkeys administrated with new Shengmai injection showed untypical symptoms of anaphylactoid reactions and the content of serum histamine did not rise.

CONCLUSIONThe old Shengmai injection can induce typical anaphylactoid reactions on Cynomolgus monkeys, and the sensitization ability is strong. The symptoms of anaphylactoid reactions induced by the new Shengmai injection appeared later and showed lesser degree with the sensitization lower.

The detection of drug-induced anaphylactoid reactions remains a global challenge,still lacking mature and reliable animal models or test methods. Therefore,the purpose of this paper is to explore and establish the test methods and evaluation standards for anaphylactoid reactions that apply to injection drugs. Based on the anaphylactoid reaction symptoms of mice induced by intravenous injection drugs C48/40 and Tween 80,a list of systemic anaphylactoid reaction symptoms in mice was sorted out and an evaluation standard of anaphylactoid reactions symptoms was established by applying symptom intensity coefficient K( that can represent these verity of anaphylactoid reaction symptoms) and its calculation formula Accordingly,histamine,tryptase,and Ig E were selected as blood indicators of anaphylactoid reactions,so that a test method combining symptoms evaluation and blood makers detection was established.This test method could be used to evaluate the characteristics of anaphylactoid reactions: coefficient K,blood histamine levels were highly and positively correlated with C48/80 and Tween 80 dose; The log value of histamine was highly and positively correlated with K; tryptase level may rise,or remain steady,or drop,possibly associated with the characteristics of the tested object and time for blood taking; and Ig E level would drop or remain steady,but it would not rise,which can be clearly distinguished from type I allergic reactions. On this basis,tiohexol,iopromide,paclitaxel,Xuesaitong Injection,Shuanghuanglian Injection and Shengmai Injection were used to investigate the applicability. The testing results showed a high degree of consistency with the actual clinical situation. The results suggest that the method of systemic anaphylaxis test in mice has high sensitivity,specificity and good consistency with clinical practice.It is suggested to be further validated and popularized.

In this paper, literature about adverse reaction induced by Puerarin injection published in recent years were reviewed and analyzed. It was reported that Puerarin injection can not only induce adverse reactions on multiple systems, such as immune, blood, urinary, digestive and cardiovascular system, but so far as to cause death. Therefore, it should be administered rationally and strictly according to the direction and the course of medication should be rigorously monitored to prevent the occurrence of adverse reactions.
