The Development Of A Course Of Study In Fda Drug Regulatory Procedures, Robin Adele Wills

University of the Pacific Theses and Dissertations

It is the purpose of this thesis to develop a course of study for pharmacy schools on drug regulation by the Food and Drug Administration (FDA). A summarization of the history of the development of the Food and Drug Administration (FDA) and of pharmacy education reveals a lack of interface between the two. The necessity for the interface of pharmacy education and the agency which has significant control over the products forming the basis of the pharmacy profession will be made apparent. A period of residency through which the course of study on drug regulation by the FDA was to …

The Chemistry Of Pesticides, Walter R. Benson

United States Food and Drug Administration: Publications

Introduction

This review is limited to the structures and a few reactions of the pesticides mainly insecticides-that affect mammalian systems and that are the subject of papers by other authors in this monograph. There is no attempt to give a complete review of the chemistry of pesticides. It is intended only to show the breadth and depth of pesticide chemistry through the use of examples. With proper use of the references, and of the papers by Crosby, Freed and Montgomery, and Owens in this monograph, the reader will be able to find information for other chemicals.

Quantitative Calculation Of Gas Chromatographic Peaks In Pesticide Residue Analyses, Jean A. Gaul

United States Food and Drug Administration: Publications

Comparison of five methods for calculating gas chromatographic peaks (disc integration, triangulation, peak height X width at half height, R_t X peak height, and peak height) shows no significant difference in the calculated results when aldrin, heptachlor epoxide, and dieldrin are injected into a gas chromatograph equipped with electron capture detector.

Problems are associated with the calculation of toxaphene, chlordane, DDT, and BHC. The author makes suggestions for calculating these four residues when present individually and in combinations with other pesticides. Use of the last four toxaphene peaks compares favorably with results obtained by using the entire toxaphene curve. …

Analysis Of Pesticide Residues By Polarography, Raymond J. Gajan

United States Food and Drug Administration: Publications

Polarography is a rapid, sensitive, and relatively specific technique that can be applied to pesticide residue analysis. The technique should also prove a valuable tool in overall pesticide research, such as monitoring new columns, studying kinetics, identifying and determining metabolites, assaying primary pesticide standards, and conducting stability studies.

Diphenylamine-Zinc Chloride As A Chromogenic Agent For The Detection Of A Mixture Of Ddt, Chlordane, And Toxaphene On Thin Layer Chromatograms, Lewis J. Faucheux Jr.

United States Food and Drug Administration: Publications

Diphenylamine-ZnCI, has been evaluated as a chromogenic agent for detection of toxaphene, DDT, and chlordane on Al₂O₃ a thin layer plates. Characteristic colors were obtained for these pesticides; a lower level of about 5 μg was detectable. Color reactions of 34 pesticides at the 20 μg level are presented.

Pesticide Residues, J. William Cook, Sidney Williams

United States Food and Drug Administration: Publications

METHODOLOGY for residue analysis has advanced rapidly during the current review period, from November 1962 through October 1964. Notable progress has been made in the development and refinement of methods of analysis by which any or all of a large number of pesticide residue chemicals can be detected and measured in one general operation. This is of particular significance because great interest has developed-outside the scientific community as well as within - in the possible presence of pesticide chemicals in all parts of our environment, including man himself. Only by the use of improved methodology will it be possible to …

Exposure To Parathion Effect On General Population And Asthmatics, Robert S. Ganelin, Cipriano Cueto Jr., G. Allen Mail

United States Food and Drug Administration: Publications

There has been much lay and medical concern regarding toxic effects of insecticides on the general population. In addition to direct toxic effects, it is suspected that insecticidal application has deleterious physical effects on persons with respiratory diseases. To evaluate some of these problems, the authors have attempted to quantitate actual absorption, symptoms, and laboratory evidence of intoxication in persons with varying degrees of exposure to parathion. By means of controlled observations, the respiratory effect of application of this compound on persons with bronchial asthma was also measured. The results suggest that the effect of this chemical on the general …

Application Of Oscillographic Polarography To Determination Of Organic Phosphorus Pesticide Residues, Raymond J. Gajan

United States Food and Drug Administration: Publications

Some organic phosphorus pesticides have been determined successfully by polarography (1-7). However, in most cases the methods were used to determine the pesticide in commercial formulations. Little has been reported on the polarographic determination of microgram amounts of these pesticides such as those encountered in pesticide residue analysis.

Many of the methods used for the determination of these pesticides are nonspecific. They are based on cholinesterase assay (8- 12), radioactive tracer analysis (13, 14), total phosphorus (15-17), and paper chromatography (18-24).

In this paper we will discuss the polarography of Systox, Di-Syston, and· Thimet and some of their oxidation products, …

Swine Brucellosis And Human Health, Us Public Health Service

United States Food and Drug Administration: Publications

Swine brucellosis is caused by Brucella suis, a strain of bacteria which also cau ses human brucellosis, or undulant fever. T his disease is an imp 0 r tan t public health problem which affects thousands of farmers, livestock handlers, meat processors, and butchers .. The U. S. Department of Agriculture estimates that 6.15 percent of the 1.8 million swine herds in the Nation are infected with brucellosis. This represents about 131,000 in f e c ted herds on farms, where some 579,000 farm people come into daily c ontact with these herds. The infection rate among these rural persons …
