Objective To observe the anaphylactoid reactions of Shuanghuanglian injection, determine the serum histamine level of sensitized animal, and to investigate its correlation with anaphylactoid reactions.Methods The guinea pigs were randomly selected to observe the anaphylactoid reactions using Shuanghuanglian injections in the different injection speed or different doses, and the serum histamine and the serum IgE of sensitized animals were determined by ELISA. Results The anaphylactoid reactions were induced by Shuanghuanglian injections in the different conditions of injection speed and doses in guinea pigs. There were no obvious difference about the serum IgE level between Shuanghuanglian group and saline group were injected in injection speed and doses. The serum histamine level was significantly increased in Shuanghuanglian group both different conditions of injection speed and doses, and it related to doses and speed. Conclusion Shuanghuanglian injection can cause anaphylactoid reactions in guinea pigs, and the changes of serum histamine level are related to injection speed and doses of Shuanghuanglian injection.

This study was aimed to investigate allergic reactions of traditional Chinese medicine (TCM) injections, and to determine contents of serum IgE in sensitized animals. The correlation between preceding contents in serum and allergic reactions may be found, in order to offer experimental evidences for advancing the accuracy of anticipa-tion by allergic reactions. Passive cutaneous anaphylaxis (PCA) tests and anaphylactoid reactions were used in a vari-ety of TCM injections. ELISA method was used to determine the content of total serum IgE in sensitized animals. The PCA results of SHL, QKL, YXC, XST, GGS and CHN were negative. The PCA result of CWJ was positive. There was no significant difference for total serum IgE level between the experimental group and the normal saline group in the group of SHL, QKL, YXC, XST, GGS, CHN and CWJ. All TCM injections caused anaphylactoid symp-toms in guinea pigs. It was concluded that all TCM injections can cause allergic reactions in guinea pig. And the al-lergic reactions of TCM injections were not correlated with serum total IgE.

OBJECTIVETo study the damage of Agrotis ypsilon on Scrophularia ningpoensis and the control method, so as to provide scientific basis for its integrated pests management (IPM).

METHODThe field investigation and the field controlling trial were carried out for the research.

RESULTThere is obvious relationship between the pre-season crops and the damage degree of S. ningpoensis. The damage rate of the fields which had planted maize and tobacco in the last planting season was much higher than that of the other fields. The average damage rate could reach 12.43% and 15.68%. The result of five pesticides against A. ypsilon in field trial showed that the controlling effect of 10% beta-cypermethrin EC 2000 times and 40% chlorpyrifos EC 1500 times were 92.53% and 91.69%, respectively.

CONCLUSIONA. ypsilon could be well controlled while 10% beta-cypermethrin EC or 40% chlorpyrifos EC are sprayed during the period of seedling.
