Controversy exists over a direct effect of 1,25(OH)2D3 on PTH secretion. To investigate the possibility that the suppressive effect of 1,25(OH)2D3 on PTH secretion may be demonstrable in 1,25(OH)2D3-depleted tissue and/or after prolonged periods of exposure to 1,25(OH)2D3, primary monolayer cultures of bovine parathyroid cells were established in 1∶1(More)
The effects of intraperitoneal aluminum chloride (1.5 mg aluminum/kg/day for 9 weeks) were studied in normal and uremic rats. Parameters measured included tissue aluminum, serum vitamin D metabolites, and quantitative bone histology. Aluminum administration increased tissue concentrations of this metal in uremic and nonuremic animals. Bone aluminum(More)
Biochemical data and skeletal histomorphometric measurements are presented for normal rats and for two groups of rats rendered uremic by partial nephrectomy. In one of these groups chronic acidosis was induced by the oral administration of hydrochloric acid. Uremic animals had higher urine calcium excretion rates and lower serum concentrations of vitamin D(More)
