DISTRIBUTION OF IODINE IN THYROID GLAND 



179 



DISCUSSION 



If we consider the data described above we find that following the 

 stimulation of a given lobe of the thyroid gland there was no consistent 

 change in the concentration of iodine in that lobe compared with the

A comparison of the effect of the different methods of stimulation of the vago-sympa- 

 thetic nerve on the concentration of iodine in the thyroid gland of the dog 



nonstimulated lobe. Following stimulation there was an apparent 

 diminution in the concentration of iodine in 24 or 54.5 per cent of the 

 stimulated glands, and an apparent gain in 20 or 45.5 per cent of glands 

 stimulated similarly. Watts (3) reported that the average difference
