Experimental study on anaphylactoid reactions induced by different components of shengmai injection (new production process) on Beagle dogs / 中国中药杂志

<p><b>OBJECTIVE</b>To evaluate the sensitization effect of different components of Shengmai injection (new production process) on Beagle dogs.</p><p><b>METHOD</b>Beagle dogs were randomly divided into 7 groups, 3 in each group. Each group was respectively injected with 5% glucose injection, Ginseng Radix et Rhizoma Rubra extract, Ophiopogonis Radix extract, Schisandrae Chinensis Fructus extract, Schisandrae Chinersis Fructus distillate, Shengmaifang, 0.2% tween 80. The changes of each dog 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 by ELISA. Sensitization of the injection was comprehensively determined by combined the response level of symptoms and the histamine level.</p><p><b>RESULT</b>One dog of Ginseng Radix et Rhizoma Rubra extract group showed untypical symptoms of anaphylactoid reactions, and serum histamine of two dogs increased more than doubled. The Beagle dogs administrated with 0.2% tween 80 showed typical symptoms of anaphylactoid reactions, while there was no significant increase of serum histamine. Other groups were observed with no typical anaphylactoid reactions.</p><p><b>CONCLUSION</b>The sensitization effect of Shengmai injection (new production process) may be associated with Ginseng Radix et Rhizoma Rubra extract and 0.2% tween 80.</p>

Experimental study on anaphylactoid reactions induced by shengmai injection (new production process) on Cynomolgus monkey / 中国中药杂志

<p><b>OBJECTIVE</b>To compare the anaphylactoid effect of old Shengmai injection and new Shengmai injection on Cynomolgus monkey.</p><p><b>METHOD</b>Cynomolgus 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.</p><p><b>RESULT</b>The 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.</p><p><b>CONCLUSION</b>The 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.</p>

Experimental study on anaphylactoid reactions of guinea pig induced by danshen injection and its components / 中国中药杂志

<p><b>OBJECTIVE</b>To compare the anaphylactoid effect of Danshen injection and its components on guinea pig.</p><p><b>METHOD</b>Applying active systemic anaphylaxis (ASA) tests, the corresponding experimental injections were administrated to guinea pigs to sensitized, and allergen with double doses was injected to stimulate in the 11 days after the last sensitized. The anaphylaxis situation of guinea pigs was observed.</p><p><b>RESULT</b>Danshen injection and its components are suspicion on guinea pigs, while negative reaction was observed on guinea pigs which injected by the liquid excipients of Danshen injection.</p><p><b>CONCLUSION</b>Danshen injection using the ultrafiltration method still have some antigenic impurities which cannot be removed completely, and this may be one of the reasons for anaphylactic reaction.</p>
