The experiments reported here were designed to reconfirm Yun and Montagna's findings and to determine one the long-term effects of UV light on pigment cells 2 whether stimulated. Pigment cells can be restimulated after a period of rest and three, whether tyrosinase activity increases and remains at a high level with UV stimulation or decreases once it reaches this peak, and for how ultra structural features relate to DOPA - positivity in melanocytes. 000001794 542__ $$fIn copyright - single owner 000001794 650__ $$aUltraviolet Rays$$027554 000001794 650__ $$aPigmentation$$024154 000001794 650__ $$aRadiation Effects$$025069 000001794 650__ $$aMacaca mulatta$$021724 000001794 650__ $$aMelanocytes$$021988 000001794 691__ $$aUO Medical School$$041362 000001794 692__ $$aUOMS Department of Anatomy$$041392 000001794 7001_ $$aErickson, Kent L.$$uUniversity of Oregon$$041359 000001794 7201_ $$aMontagna, William$$uUniversity of Oregon$$041359$$7Personal$$eThesis advisor 000001794 7201_ $$aBrookhart, John M.$$uUniversity of Oregon$$041359$$7Personal$$eCommittee chair 000001794 8564_ $$uhttps://digitalcollections.ohsu.edu/record/1794/files/197407.erickson.kent.optimized_redacted.pdf$$9512d545f-ea9c-4ff9-b3a9-891e3b699c95$$s12216655$$ePublic$$2ef45fa3827ff427fab004dca6b2d36ca$$31 000001794 905__ $$a/rest/prod/9s/16/16/31/9s1616317 000001794 909CO $$ooai:digitalcollections.ohsu.edu:1794$$pstudent-work 000001794 980__ $$aTheses and Dissertations
