The Effect Of Hypercholesterolemia On The Membrane Lipids, 3-0-[¹⁴C] Methylglucose Transport, And 2,3-Diphosphoglycerate Levels In Rat Erythrocytes, Edwin J. Lester Jr.

Loma Linda University Electronic Theses, Dissertations & Projects

An increase in dietary cholesterol and cholic acid will produce hypercholesterolemia in rats. For ten months, two groups of rats (six in each group) were fed commercial rat pellets (control group) or rat pellets plus cholesterol (1%) and cholic acid (0.25%) (experimental group). A blood sample from each animal was divided into three aliquots for three separate experiments on the erythrocytes: a membrane cholesterol and phospholipid determination, a 3-0-[¹⁴C] methylglucose (30MG) transport determination, and a 2,3-diphosphoglycerate (2,3 DPG) determination. The 30MG transport and 2,3 DPG aliquots were each incubated in the same five concentrations of 30MG and glucose …

A Morphometrical Analysis Of The Guinea Pig Placenta After Chronic Exposure To Carbon Monoxide, Marcella J. Woolsey

Loma Linda University Electronic Theses, Dissertations & Projects

We used morphometric analysis to determine if placental structure is modified by carbon monoxide, Camm-Hartley guinea pigs were exposed throughout gestation to chronic conditions of carbon monoxide (averaging about 180 parts per million). Maternal weight, placental weight, fetal weight, and fetal length were recorded at the time of placental fixation. Using a computerized image analyzer on photomicrographs obtained through light microscopy, we measured maternal and fetal percent vessel volumes, surface areas, and vessel numbers. Maternal vessel numbers and surface area remained basically unchanged but decreased slightly. Maternal percent volume decreased 15%. However, fetal capillary number increased 35% (p < 0.01) from a control value of 2325 ± 184 per mm² (SE …

The Effect Of Folic Acid Supplementation On Gingival Healing After Oral Hygiene Therapy, Marilyn J. Wankier

Loma Linda University Electronic Theses, Dissertations & Projects

To determine the effect of folic acid supplementation on gingival healing after oral hygiene therapy, eight teeth (#3, 4, 5, 6, 11, 12, 13, 14) of sixteen human subjects with moderate levels of gingival irritation were studied. Clinical parameters included measurement of gingival fluid, pocket depth, bleeding upon probing, and plaque. Serum and red blood cell folic acid levels were determined using radioimmunoassay (RIA). Based on clinical parameters and serum folate levels, two similarly matched groups were established. The teeth were scaled and polished. Brushing and flossing instructions were given.

After one week of oral hygiene therapy alone, the experimental …

Fight For Alternatives Gathers Momentum: Commitments To Help Lab Animals Are Extracted From Industry And Government

Close Up Reports

The Humane Society of the United States wants to see an eventual end to all pain and suffering inflicted on animals in the laboratory. We are working hard to make this happen, and the "alternatives" concept is basic to our program. We want scientists to find alternative methods of testing and experimentation that do not involve the use of animals.
