Abstract
|
|
|
A survey was carried out in order to figure out of phenomenons in daily variation of leukocyte counts in normal man and rat; ACTH injected rat, from Oct. 1, 1673 to March 31, 1974.
The blood was examined approximately every two hours for a day (810 times).
The blood for the leukocyte counts and cover glass smears was taken from the lobe of the ear of the man and from the capillaries of tail of the rats.
The direct manual method was used in counting each person´s blood.
The results of this study were as follows:
A daily variation of leukocyte counts during a day are:
1. Leukocyte count of man was shown the lowest degree during the forenoon, and it was shown the highest degree around the midnight.
2. Leukocyte count of male and female was shown the same pace with both sexes in man.
3. N´eutrophil count was not shown any differences in between man and rat (normal rat and ACTH injected rat), but eosinophil and lymphocyte count was shown the opposite levels during a day.
4. Eosinophil and lymphocyte counts were keeping same pace with both in normal rat and ACTH injected rat.
5. From two hours upto four hours latter eosinophil count was more decreased than normal group after ACTH injection on rat; there after, it was not more decrease.
