Exposure to light and pheophytin associated with a reduction in inflammation.
(A) SKH1-Elite, hairless mice, pictured, were fed a chlorophyll free diet. For two groups of mice, we added pheophytin to the diet; the absorption spectrum of which is shown. Animals were then raised either under yellow light, which minimally excites pheophytin, or incandescent light, which contains red wavelengths, that can excite pheophytin. Approximate absorption bands of the lights used are shown. (B) Plasma α-2 macroglobulin levels in the above described, 4 groups of mice (n = 5 to 7), after 4 months of treatment. Averages and 95% confidence intervals are shown. *P-value < 0.05, determined by unpaired, two sided, Student’s t-test.
