Thirteen healthy adult males, ages 20-40, consuming self selected
diets, were given instructions to take one 500 mg tablet of ascorbic
acid three times a day with their meals for a period of ten weeks. The
effect of this daily supplementation on copper status was investigated.

Although fluoride is an important trace element in the prevention of dental caries,
it has a narrow range between beneficial and toxic effects. Excessive fluoride intake for
example can cause dental fluorosis in infants and children whose teeth are still
developing. The primary source of this unwanted fluoride has been...
The hypotheses of this research were (1) to test if
the antagonistic effect of ethanol on liver copper could
be seen within a short period when ethanol ingestion,
low dietary copper and high metabolic demand represented
by either pregnancy plus lactation or rapid growth are
simultaneously present and (2) to...
The present study sought to define a possible role of phosphorus-stimulated
ammoniagenesis, previously observed in vitro and in
experimental animals, in the hypocalciuric effect of phosphorus in young
men. It was hypothesized that titrating some of the hydrogen ions
destined for excretion with ammonia would be beneficial to kidney
calcium...
This study was designed to determine whether
dietary protein is a nutritional factor influencing the
bioavailability of dietary fluoride. To accomplish
this, a factorial experiment was conducted with
weanling rats fed a purified diet to determine the
influence of dietary protein type (casein or
lactalbumin) and level (12% or 36%)...
This research was designed to study the perinatal and
postweaning effects of the interaction between ethanol and low
dietary zinc during gestation and lactation in the rat.
Pregnant rats were fed liquid diets containing either 2 or 10
μg zinc/ml with or without 30% of kcal from ethanol throughout
gestation...
Pregnant and weanling rats were fed liquid diets with
or without 30 percent of total kcal from ethanol and varying
levels of copper in order to determine if ethanol ingestion would
exaggerate a marginal copper status to an obvious copper
deficiency. Pregnant albino rats were fed either 0.75 or 3.75...
Eight adolescent males (14 to 18 years old) were evaluated
before and after 50 minutes of exercise on a bicycle ergometer
at 60 percent of their maximal heart rate to investigate the
relationship between blood magnesium status and the derangement
of other serum electrolytes in the etiology of "sports anemia."...
Two factorial experiments were conducted to determine if
high dietary fluoride would inhibit selenite toxicity in
rats. In each study, two levels of selenite (0.05 and 5
mg/kg diet) were matched against two levels of fluoride (1
and 150 mg/kg diet) for either 6 or 8 weeks. Fluoride failed
to...
