The Role Of The Salivary Glands In Uptake Of Fluoride In Teeth And Bone, Robin E. Vance

Loma Linda University Electronic Theses, Dissertations & Projects

The cariostatic capability of fluoride is generally recognized, in addition, it may also have a beneficial effect on bone. Fluoride is thought to exercise its cariostasis through a local effect on teeth, however, the possibility exists that fluoride exerts its action through a systemic mechanism. Fluoride uptake by rat teeth and its effectiveness as a cariostatic substance was studied in parotidectomized, submaxillariectomized, and totally sialoadenectomized animals (both parotid and submaxillary glands removed). The uptake of fluoride in bone was also quantitated for comparison purposes.

Rats were injected daily with 15 micromoles of fluoride dissolved in 0.1 ml saline. The rats …

The Effect Of Dietary Alpha - Linolenic Acid On Apparent Risk Factors Of Cardiovascular Disease, Kelvin D. Lindbeck

Loma Linda University Electronic Theses, Dissertations & Projects

Eight healthy male lacto-ovo-vegetarian subjects averaging 28.0 ± 3.6 years of age (22 to 53 years) were fed a diet rich in α-linolenic acid (18:3 ω 3) for four weeks. Arterial blood pressure and body weight were recorded each week. Plasma 6-keto-prostaglandin F_1α (6-keto- PGF_1α ), thromboxane B₂ (TXB₂), total cholesterol, triglyceride, and total phospholipid fatty acid composition were analyzed at 0, 2 and 4 weeks.

Systolic blood pressure increased significantly between weeks 0 and 1 (106.5 ± 2.7 mmHg to 114.0 ± 3.7 mmHg; p < 0.003), but decreased to 107.3 t 2.6 mrHg (p < 0.02) at week 2. There was an insignificant increase in both systolic and diastolic blood pressures after four weeks. There was no significant change in either total cholesterol or triglyceride levels during the four weeks.

Plasma 6-keto-PGF_1α levels increased significantly from 60.13 ± …
