Any other information on results incl. tables

Hematotoxicity:

Considerable amounts of methemoglobin (2,4 %) were detected in the blood after 2 weeks of treatment. A decrease in erythrocytes and hemoglobin as well as an increase of heinz bodies and reticulocytes was observed after 1 month of treatment. After 3 months an increase of the catalase index and the blood cholinesterase activity was evident and decreased phagocytic activity of leukocytes was detected. Possible development of an auto-allergy against erythrocytes.

Body composition:

The relative spleen weight (organ weight/ body weight) was increased at the end of the treatment (1/10 LD50 for 3 months and its Vitamin C content decreased.
