Thyroid and adrenal responses to the dynamics of meteorologic factors.

Endocrine reactions are essential elements in bodily adjustment to external environment. The study of the endocrine-hormonal mechanisms of adjustment to the dynamic influences of natural factors has a place of its own in contemporary biology. The endocrine functions, like any other physiologic processes, do not take place with constant intensity.

Iodine-enriched milk in goiter endemics.

Researches carried out at Cîmpulung-Lereşti-Lăicăi from the north of the Argeş County demonstrated an environmental iodine-deficiency that caused thyroid hypofunction in animals and, consequently, a decrease in the iodine level in the products of animal origin. Administration of KI, KIO3 or of sea weeds powder in the cows nutrition corrected the thyroid function, the quantitative increase in milk production and enrichment of milk in iodine.

Changes in the iodine content of vegetables following the Chernobyl accident.

In the early phenophases and at maturity the vegetables grown in the goitrogenic area have a lower iodine concentration than in non-goitrogenic areas. Within the same area, the amount of iodine is higher in young than in old vegetables and, in some species, it is higher in the young vegetables of the goitrogenic area than in the nature vegetables of the non-goitrogenic ones. Following the accident at the Chernobyl Nuclear Power Plant in April 1986, the iodine metabolism in plants was disorganized.
