[Study of the endogenous calcitonin transport in the rat thyroid gland]

Regression analysis revealed a significant correlation between Nvsq and calcitonine. The regression model was then transformed into a covariation one to establish: 1) probability of all calcitonine molecules moving across the C-cell-blood barrier into the blood, 2) confidence interval of endogenous calcitonine bioavailability, and 3) estimate of the period of calcitonine half-retention by the C-cell-blood barrier.
