Wheat varieties of differential tolerance to Al were used in a
series of nutrient solution experiments to study the inhibitory effects
of Al on growth and nutrient uptake. The pH and the Al and P concentrations
were rigorously maintained to prevent the confounding
effects of Al and P precipitation and...
The objective of this study was to investigate the effect of inorganic
and organic components of molasses on the laxative problem
encountered when molasses makes up a large portion of livestock
rations. In a series of four trials 280 male Long Evans rats weighing
approximately 50 grams each were placed...
Some forms of bacterial respiration do not involve molecular
oxygen but instead utilize other hydrogen acceptors for oxidation
of the substrate. Various organic and inorganic acceptors may be
used. In the present study, the inorganic radicals, nitrate and
nitrite, were investigated. Preliminary evidence indicated that
nitrate and oxygen are able...
It is common to characterize adrenergic receptors by placing
them in one of two categories, alpha or beta. The receptors responsible
for adrenergically induced increase in cardiac contractile force
and glycogenolysis are usually classified as beta receptors, but such
a classification is not definitely established. Therefore, an attempt
was made...
Attempts were made to study the effect of parathion and DDT
on the postnatal development of mice. Parathion, DDT or corn oil
(control) was administered to gravid mice during the first, second,
and third trimesters of pregnancy. Thus, nine groups of offspring
were obtained. Four different techniques, Audiogenic Seizure,
Conditioned...
