  3. Bone marrow examination

  4. Blood urea nitrogen

  5. Creatinine

  7. Cephalin flocculation

  8. Thymol turbidity

  9. Testicular biopsy (two)

  10. Electrocardiogram

Complete blood counts and bone marrow studies were repeated six weeks after termination of treatment, in each case.

In addition, patch tests were performed on 200 individuals, including 28 who had previously received griseofulvin internally. A water-soluble base containing 5% griseofulvin was used. The base, alone, was used as a control.
