Spectrophotometric And Microbiological Determination Of The Stability Of Sodium Ampicillin As Affected By Ph, Enrico Frank Raffanti Jan 1972

Spectrophotometric And Microbiological Determination Of The Stability Of Sodium Ampicillin As Affected By Ph, Enrico Frank Raffanti

University of the Pacific Theses and Dissertations

The specific purpose of this investigation was to determine the effect of pH on the stability of ampicillin sodium for injection. Then, to correlate this information, a pH profile may be established to predict chemical stability with ampicillin sodium alone or when other drugs may be included in the admixture. With a pH profile the pharmacist could predict the length of time after which more than a 10 percent loss of activity would occur. Stability measurements were to be accomplished through a microbiological assay after adding ampicillin sodium to different buffer solutions. At the end of four hours, eight hours, …


Aspects Of The Oculomotor System Of Callinectes Sapidus, Antoinette Steinacker Jan 1972

Aspects Of The Oculomotor System Of Callinectes Sapidus, Antoinette Steinacker

University of the Pacific Theses and Dissertations

An isolated perfused preparation was developed for the study of several aspects of the oculomotor system of the blue crab, Callinectes sapidus. The system for eyestalk rotation was investigated on an extracellular level. Two antagonistic pairs of muscles under visual and statocyst control were found to be responsible for stabilization and rotation of the eyestalk. The primary sensory input to the muscles appears to be from the statocysts, with both static position sense and dynamic acceleration components influencing the motor response. Two sensory feedback systems from mechanoreceptive hairs were found which influence the response of the eye stalks to statocyst …


Pharmacologic Investigation Of The Anti-Inflammatory Activity Of Cryogenine And Selected Benzoquinolizine Derivatives, Louis Decato Jan 1972

Pharmacologic Investigation Of The Anti-Inflammatory Activity Of Cryogenine And Selected Benzoquinolizine Derivatives, Louis Decato

University of the Pacific Theses and Dissertations

It has become apparent in recent years that many centrally active agents possess potential anti-inflammatory capabilities. The central or peripheral mechanisms of action for these agents have not been delineated nor has their clinical efficacy baan established or refuted. The centrally active drugs, cryogenine and tetrabenazine (a benzoquinolizine derivative), previously have been shown in this laboratory to inhibit certain models of induced inflammation. The present study in rats verifies the anti-inflammatory properties of cryogenic and established that a structurally related series of benzoquinolizine derivatives possessed the capability of inhibiting both exudative (carrageenan-induced pedal edema) and proliferative (cotton pellet granuloma) models …

Experimental Modification Of Attitudes Toward Birth Control, Peggy C. Hunter Jan 1972

Experimental Modification Of Attitudes Toward Birth Control, Peggy C. Hunter

Theses, Dissertations and Capstones

It is apparent in both lay and professional literature that we are living in an age of social crises. Clearly the shortage of resources and the problems of pollution and poverty would be greatly ameliorated if our birth rate were controlled. Despite this, a survey of psychological literature reveals a paucity of articles on birth control. Psychologists largely have their heads in the sand with regard to research to understand factors associated with childbearing. Meanwhile, the birth rate soars on and it is increasingly obvious that something must be done.


The Anatomical Relationships, Ultrastructure, And Function Of The Pineal Gland In Some Common Laboratory Rodents, Joseph Chester Gregorek Jan 1972

The Anatomical Relationships, Ultrastructure, And Function Of The Pineal Gland In Some Common Laboratory Rodents, Joseph Chester Gregorek

Theses and Dissertations

The pineal complex of rodents is made up of a pineal organ which developmentally always originates from the area between the habenular and posterior commissure and a pineal sac which is continuous with the choroid plexus of the third ventricle. This sac appears to be identical to the choroid plexus at both light and electron microscopic levels. The pineal sac abuts the deep and superficial pineal organs of the golden hamster. In the PET mouse, gerbil, kangaroo rat and Chinese hamster, the sac is contiguous with only small areas of pinealocytes. This sac never abuts true pineal parenchyma in the …

Metabolic Role Of Sulfates And Sulfides Producing Bacteria In Pollution Of Waters, M. I. H. Aleem Dec 1971

Metabolic Role Of Sulfates And Sulfides Producing Bacteria In Pollution Of Waters, M. I. H. Aleem

KWRRI Research Reports

Cytochrome transport particles from Nitrobacter catalyzed nitrite, ascorbate as well as NADH oxidation with concomitant phosphate esterification yielding P/0 ratios of 1.0, 0.6 and 2.0 respectively. Phosphorylation coupled to nitrite oxidation was not effected by rotenone, amytal or antimycin while 50 and 70% inhibition of the NADH-linked phosphorylation was observed in the presence of HOQNO and rotenone respectively. Cell-free extracts from Nitrobacter also catalyzed an energy-dependent reduction of NAD+ by nitrite. The reduction of cytochrome c by NŌ2 was energy-dependent which involved the reversal of electrons from cytochrome a1. The subsequent energy-linked reduction of the flavoproteins …
