Somatomedin activity was measured using an embryonic chick cartilage assay in 33 normal and short normal children, 23 children with pituitary growth hormone (GH) deficiency, 14 children with sexual precocity, and 13 children with chronic renal insufficiency. In normal children somatomedin activity correlated well with chronological age: low valles in early childhood rose to higher than adult le...

Investigations carried out in 1931-32 revealed that the plasma phosphatase is increased in active rickets', the degree of increase corresponding to the severity of the disease. They also showed that, whereas the serum calcium and phosphorus rapidly returned to the normal amount under treatment, the decline in the figures for phosphatase was much more gradual, normal values not being regained un...

BACKGROUND It is well known that smoking and pregnancy induced hypertension (PIH) are associated with decreased fetal growth. It has been reported that in preeclampsia the fetal growth deficit attributable to smoking is higher, which has been contradicted in other studies. We therefore evaluated the effects on fetal growth of early- and late onset PIH and chronic hypertension and how cigarette ...

Derangements in serum phosphate level result in rickets/osteomalacia or ectopic calcification indicating that healthy people without these abnormalities maintain serum phosphate within certain ranges. These results indicate that there must be a regulatory mechanism of serum phosphate level. Fibroblast growth factor 23 (FGF23) was identified as the last member of FGF family. FGF23 is produced by...

Growth plate cartilage development is commonly referred to as endochondral ossification which is the end stage of long bone development. Endochondral ossification proceeds as a continuum of chondrocyte proliferation cycles followed by non-proliferative phases couple...
