Vitamin D and its' metabolites are a crucial part of the endocrine system that controls whole
body calcium homeostasis. The goal of this hormonal control is to regulate serum calcium …

In order to determine the prevalence and severity of hepatic osteodystrophy by non-invasive
means we compared 115 consecutive ambulant patients with histologically proven chronic …

To measure the effect of testosterone replacement and venesection on spinal and peripheral
bone mineral we prospectively studied six hypogonadal men and six eugonadal men with …

Studies were carried out to explore the influence of soy protein and food restriction on age-
related changes in serum PTH and bone. Three groups of male Fischer 344 rats were …

The effect of vitamin A on calcium-regulating hormones was studied in rats. A single oral
dose of 30 mg retinol equivalents (RE) given to adult rats caused no change to serum …

The induction of 1‐hydroxylase in alveolar macrophages by tumor necrosis factor‐alpha
(TNF) was examined in view of recent evidence suggesting that local production of 1, 25 …

Absorption of dietary calcium from the rumen is a quantitatively important process in calcium
homeostasis of ruminants. In 3 separate experiments in dairy cows, we applied a technique …

We measured the concentrations of vitamin Dbinding protein (DBP), total 25-hydroxyvitamin
D, total 1, 25-dihydroxyvitamin D [1, 25-(OH) 2D], and free 1, 25-(OH) 2D in sera of 107 …

In order to study the role of trace elements as potential osteoblastic toxins, we measured
bone aluminum, copper, and iron in 106 ambulant patients with histologically proven liver …

The work presented here examines the possible effects of nutritional deficiencies on the
characteristics of the plasma transport protein for vitamin D and its metabolites (vitamin D …
