Abstract

INTRODUCTION  In this report we have collected our observations on the relation of the iodin content to the structure of the thyroid to include sheep, ox and hog thyroids. It is thus only a continuation of the work previously reported1 concerning dogs' thyroids. The methods used and the anatomic classifications adopted are the same as those fully described in the above-mentioned article and elsewhere.2

COMPARISON OF THE IODIN CONTENTS OF SHEEP, DOG, HOG AND OX THYROIDS WITH THEIR RESPECTIVE ANATOMIC STRUCTURES  The following tables are compiled from iodin determinations made on the thyroids of 40 sheep, 67 dogs, 26 hogs and 37 oxen. As the basis of these tables we have used nine anatomic groups, viz.:

  1. 1. Normal glands.

  2. 2. Colloid glands (goiters).

  3. 3. Colloid-early glandular hyperplasia.

  4. 4. Normal-early glandular hyperplasia.

  5. 5. Early-glandular hyperplasia.

  6. 6. Early-moderate glandular hyperplasia.

  7. 7. Moderate glandular hyperplasia.

  8. 8. Moderate-marked glandular hyperplasia.

  9. 9.
