Analysis Of Pesticide Residues By Polarography, Raymond J. Gajan

Food and Drug Administration Papers

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.

Food and Drug Administration Papers

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.

Antibiotics And The Wasting Disease In Neonatally Thymectomized Rats, Douglas M. Grignon

Loma Linda University Electronic Theses, Dissertations & Projects

The administration of the antibiotic, Chloramphenicol, to pregnant rats just prior to, and for four days after delivery, diminishes the incidence of the so-called "Wasting Disease" in neonatally thymectomized rats.

A total of 50 rats were divided into the following groups:

1. Thymectomy only---nonmedicated 17 rats
2. Thymectomy only---medicated 12 rats
3. Thymectomy-adrenalectomy---nonmedicated 5 rats
4. Thymectomy-adrenalectomy---medicated 8 rats
5. Controls---nonmedicated 4 rats
6. Controls---medicated 4 rats

Chloramphenicol was administered in the drinking water to the mothers of groups 2, 4 and 6 for about 2 days prior to delivery and 4 days after. On the day of birth or within three days after birth, the …

Pesticide Residues, J. William Cook, Sidney Williams

Food and Drug Administration Papers

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 …

A New Experimental Approach To The Evaluation Of The Effect Of Narcotic Analgesics Upon Respiratory Function, Charles H. Pierce, Richard B. Mchugh, Raymond N. Bieter

Journal of the Minnesota Academy of Science

Experimental models often used to study the effects of drugs upon respiratory function employ anesthetized animals. The present study eliminated the possible interference of anesthetics by using dogs altered only by a Permanent lracheostomy. Respiratory function was evaluated by determining end-expiratory (alveolar) CO, tension. The experimental design, an extension of the cross-over type, permitted the estimation of possible residual effects of the drugs applied in sequence la the same animals. Morphine Sulfate increasingly caused on elevation in alveolar pCO, while Meperidine HCl had no such effect. An antitussive meperidine derivative, WIN 13187, had respiratory effects similar to meperidine.

The Relative Efficacy Of Selected Drugs Upon The Physical Activities And The Attention Span Of A Ten Year Old Brain-Damaged Child, Ruth Elaine Atkinson

Master's Theses

The purpose of this study was to determine the relative efficacy of selected drugs in reducing the hyperactivity end increasing the attention span of a ten-year old child who had been medically diagnosed as having brain damage.

The evaluation of the effects of three drugs, Chlordiazepoxide (librium), Fluphenasine Hydrochloride (Prolixin), Thioridazine (Mellaril), and a combination of Mellaril and Methylphenidate Hydrochloride (Ritalin), was made by a psychiatrist after consideration of (1) written observations of the child’s school activities during a two-hour period, (2) a tabulation of data based on the observations, (3) reports made by the parents and teacher of the …

Hallucinogenic Drugs, James S. Watkins

Honors Theses

Hallucinogenic drugs have been used for centuries by primitive. man to produce mystic effects usually in religious rites. Perhaps these drugs would not have obta:lned the forefront. they had for while if two Harvard professors, Dr. Timothy Leary and Dr. · Richard Alpert, had not conducted campus experiments with undergraduate students. Working mainly with mescalnie and psilocybin, Leary and Alpert were trying to observe the emotional impact of the drugs and the consciousness broadening power of the drugs. No one, seemed to realize that Alpert and Leary were convinced that the mystic insight one could get from psilocybin would be …
