Anaphylactic Microshock of the Guinea-Pig by H
Brit. J. Pharmacol. (1963), 21, 414-418. THE EFFECT OF SOME NEW ANTIHISTAMINES ON THE ANAPHYLACTIC MICROSHOCK OF THE GUINEA-PIG BY H. HERXHEIMER AND E. STRESEMANN From the Asthmapoliklinik, Free University, West Berlin, Germany (Received May 14, 1963) The dose/response curves for the protective effects of the new antihistamine compounds trimeprazine, 10-(3-diethylamino-2-methylpropyl)phenothiazine 1,1-dioxide hydrochloride (oxomemazine hydrochloride), cyproheptadine, homochlorcyclizine and methotrimeprazine against the anaphylactic microshock of the guinea-pig were similar to that of promethazine. The first three compounds, however, protected at lower doses than promethazine (5 to 10 ug/kg). The protective effect of cyproheptadine lasted longer than 24 hr. The antianaphylactic effects of promethazine, mepyramine, chlorcyclizine, tri- pelennamine and diphenhydramine have been investigated by Armitage, Herxheimer & Rosa (1952). In this paper we describe investigations of a few of the newer antihistamines. METHODS The microshock method (Herxheimer, 1952) was used and the protection against anaphylactic shock was calculated according to Armitage et al. (1952) with the formula p=100(1-c/t), in which p is the percentage of full protection, c the control preconvulsion time and t the preconvulsion time of the animal under the influence of the drug. The compounds investigated were trimeprazine, methotrimeprazine, cyproheptadine, homo- chlorcyclizine and 10(-3-diethylamino-2-methylpropyl)phenothiazine 1,1-dioxide hydrochloride (oxomemazine hydrochloride, 6847 R.P.). They were injected intramuscularly in aqueous solution; the exposure to the antigen (an aerosol of 5% albumen solution) was done 1 hr later. For cyproheptadine, the exposure was delayed by between 1 and 48 hr in order to investigate the duration of the effect. -

Impact of Pesticide Use on Health in Developing Countries
Impact of pesticide use on health in developing countries Proceedings of a symposium held in Ottawa, Canada, 1 7-20 September 1990 IDRC CRDI International Development Research Centre Centre de recherches pour le devetoppement international 1 March 1993 Dear Reader/Librarian, IDRC is a public corporation created by the Canadian parliament in 1970 to help developing countries find viable solutions to their problems through research. At the 1992 Earth Summit, IDRC's mandate was broadened to emphasize sustainable development issues. As part of IDRC's strengthened commitment to global action and harüony, we are pleased to send you a complimentary copy of our most recent publication: The impact of pesticide use on health in developing countries (March 1993, 352 pages, 0-88936-560-1, $17.95). The first part of this book presents a brief survey of the global situation and the results of twelve epidemiological studies carried out by researchers from Africa, Latin America, Asia and the Middle East. These focus on poisonings resulting from organophosphates, herbicides, and pyrethroids. The second part illustrates the role of the process of development, production, spraying techniques and legislation in protecting the health of workers. A discussion of the benefits and modalities of access to pertinent information for the prevention of pesticide poisonings is provided in the third section. Finally, in the fourth section, consideration is given to the advantages and disadvantages of certain alternatives to the use of synthetic pesticides in agriculture and public health, such as botanical pesticides and integrated pest management strategies. We hope this book is a valuable addition to your collection. -
