Studies on hypoxia: XI. Long-term effects on the epiphyseal plate--a histomeric and radioautographic study

Rats were exposed to hypoxia for one week. The mean thickness of epiphyseal plates form control rats was 430 micrometers (mum) which was reduced to 313 mum in hypoxic rats. Radioautographic incorporation of 3H-phenylalaine by connective tissue cells in hypoxic rats was reduced up to 38% in control rats.
