Effects of serum obtained from stressed animals and ACTH on tyrosinase activity in cultured human melanocytes. (A) Effects of serum obtained from stressed animals in the presence or absence of corticostatin on tyrosinase activity. (B) Dose-dependent activation of tyrosinase by ACTH. Values represent the mean±SD (n=8). *p<0.001.

Effect of stress on DOPA-stain-positive melanocytes after repeated UV irradiation. (A) Microscopic magnification of DOPA-stain-positive melanocytes in mouse dorsal epidermal sheets showing tanning response after repeated UVB irradiation for 22 d. Scale bars: 100 μm. (B) The number of DOPA-positive melanocytes after repeated UV irradiation. The columns represent numbers of DOPA-positive melanocytes. The average cell number in 30 areas led to the number per 10,000 μm2.

Effect of corticostatin on DOPA-stain-positive melanocytes after repeated UV irradiation. (A) Microscope magnification of DOPA-stain-positive melanocytes in mouse dorsal epidermal sheets showing the inhibition by corticostatin of pigmentary response after UV irradiation. Scale bars: 100 μm. (B) Effect of corticostatin on the number of DOPA-positive melanocytes after repeated UVB irradiation. The columns represent numbers of DOPA-positive melanocytes. The average cell number in 30 areas led to the number per 10,000 μm2.
