Abstract
On 20 patients of appendicitis, we have observed the changes of the N. P. N. - content in the serum during pre-- and post--operative periods of appendectomy.
In every patient, N. P. N. was measured by mikro-Kjeldahl method 4 times, that is, at first just before the operation, 24 hours and 72 hours after the operation, and at last 6 days after the operation.
The results obtained were as follows:
1) The rise in the N. P. N. -content of the serum was seen in all patients 24 hours after the operation and it returned to the pre-operation value 6 days after the operation in all patients.
2) Between the patients who were administered chlorpromazin and not given it, there was no marked difference in the changes of N. P. N. - content.
3) In the group of acute type of appendicitis, the N. P. N, content was higher already before the operation, and the rise after the operation was also higher than the group of chronic type.
