Abstract
Purpose
We investigated the inhibitory effect of edaravone (EDR) lotion on chemotherapy-induced alopecia (CIA) to improve the quality of life for patients with cancer.
Methods
Wistar rats were intraperitoneally injected with cyclophosphamide (CPA, 75 mg/kg) to induce CIA and divided into six groups: (1) Control; (2) EDR 0%; (3) EDR 0.3%; (4) EDR 3%. The TUNEL-positive area was examined histologically, and mRNA expression levels of the apoptosis-related factors, such as B-cell/CLL lymphoma 2 (Bcl-2), and Bcl-2-associated X protein (Bax), were determined.
Results
In the three CPA-treated groups, a decrease in the coverage score (percentage of hairs covered) was observed from days 16 to 18. In addition, coverage scores on day 21, the last day of observation, showed a tendency for the suppression of hair loss to increase, though hair loss was observed in all groups. The coverage scores of the EDR 0.3% and 3% groups after day 17 were significantly higher than those of the EDR 0% group. The TUNEL-positive area of skin tissue on day 16 was extensive in the EDR 0% group and decreased in the EDR 0.3% and 3% groups. The mRNA expression ratio of Bcl-2/Bax on day 21 was maintained at the same level as that of the control group only in the EDR 3% group.
Conclusion
This study confirmed the use of EDR lotion to inhibit hair loss, indicating that the clinical application of EDR lotion may improve the quality of life for patients with cancer and their willingness to undergo treatment.
