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.
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
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 …
Scientific Issues And Regulation Of Primate Use, Andrew N. Rowan
Scientific Issues And Regulation Of Primate Use, Andrew N. Rowan
Experimentation Collection
Some of the patterns of use of nonhuman primates in the USA and Europe are outlined and a few specific examples of inappropriate and/or unnecessary use are described. The primate research resources program in the USA is examined and some suggestions as to how the program could be made more responsive to humane and conservation concerns are presented.
History Of Animal Experimentation Control In The U.K., Judith E. Hampson
History Of Animal Experimentation Control In The U.K., Judith E. Hampson
Laws and Legislation Collection
The legislative control of the use of animals in experiments in the UK lies in the Cruelty to Animals Act of 1876. Animal Welfare groups and individuals in Britain have pressed for reform of this law almost since its inception 105 years ago, and the British government has recently agreed to bring this legislation up to date. Any new or amended legislation could have far-reaching implications, both for laboratory animal welfare and upon the scientific community and is therefore of considerable importance both in this country and overseas. No proper appreciation of the problem would be possible without reference to …
Regulation Of Biomedical Research, Andrew N. Rowan
Regulation Of Biomedical Research, Andrew N. Rowan
Experimentation Collection
The idea of abolishing or simplifying government regulations has a large following in Washington at the moment. As Reagan and his minions start to prune the growth of the past twenty years, we must hope that they are able to distinguish between the healthy growth which provides needed support and the unnecessary growth which strangles necessary initiatives. However, there is one area where we need more regulation rather than less, namely, biomedical research. In calling for more regulation in biomedical research, I do not mean the imposition of outside controls by allegedly ignorant and insensitive bureaucrats (although I think some …
