The Synthesis And Evaluation Of The Cardiovascular Activity Of Novel Imidazole Ring Systems, Joseph E. De Los Angeles
Chemistry & Biochemistry Theses & Dissertations
An investigation was undertaken to synthesize and evaluate the cardiovascular activity of two imidazole ring systems. Imidazoles with hypotensive activity would provide novel potential antihypertensive drugs. These novel structures may also find use as chemical probes in the study of the cardiovascular system and as prototypes for other potential cardiovascular agents.
The histamine derivative, 7,7-dipyridyl-4,5,6,7-tetrahydroimidazo-[4,5-c]pyridine (ligand l), was demonstrated to possess significant hypotensive activity in laboratory rats. A 15 mg/Kg dose of ligand 1 produces a statistically significant decrease in blood pressure when injected IP. This hypotensive effect is also associated with marked increase in heart rate. Although compound 1 …

Effects Of Air Polishing And Rubber Cup Polishing On Enamel Abrasion, April Kee
Dental Hygiene Theses & Dissertations
An investigation was conducted to determine if statistically significant differences in enamel abrasion occurred when molar specimens were air polished (AP) and rubber cup polished (RCP). Thirty human molars were randomly divided into two groups. Molar buccal surfaces were masked longitudinally to provide control surfaces. Each polishing technique was applied for two minutes and thirty seconds on fifteen exposed enamel surfaces. Buccal enamel surfaces were divided into coronal and cervical sections for microscopic review. Six enamel thickness measurements were determined for each coronal and cervical enamel section using the scanning electron microscope. Measurements of AP and RCP coronal and cervical …
Determination Of Human Sperm Cell Acrosin Activity From Normal And Subfertile Men, Dilrowshan H. Haque
Determination Of Human Sperm Cell Acrosin Activity From Normal And Subfertile Men, Dilrowshan H. Haque
Chemistry & Biochemistry Theses & Dissertations
Acrosin is an acrosomal enzyme which is reported to be involved in sperm penetration through cumulus, zona, and ooplasma. This enzyme has been reported to be significantly lower in sperm of infertile men compared to sperm of fertile men. The acrosin assay which has been developed can be used for studies in patients with suspected infertility and may be used on a fraction of most semen specimens being evaluated in a clinical andrology laboratory.
Within-run precision studies yielded coefficients of variation of 11% for a low-activity pool and 9% for normalactivity pool specimens. Between-run precision studies using a single donor …
