It is planned that teams of pathologists from the Naval “edical Research Institute and the Army Medical School will be on hand to perform seriai autopies at the earliest time possible after the blast to obtain tissues for histoligic study. At the same time, tissues would be quick frozen for transmission to the Army ledical School where studies of various enzyme systems, and histochemical studies would be conducted. The freezing method contemplated is a snecial deep freeze chamber containing ¢ry ice. Air transportation to Washinston would be provided. See also 3.2.4.3, following. Personal Communications, Colonel William Stone, If. C. APPENDIX 5.2.4.5 "Dr. Doherty suggests an experiment on the effects of bomb blast on enzymesinvitro and invioo. His proposed experiment would be concerned with prompt isolation of enzyme systems from irradiated animals and determination of activity changes. Purified enzyme systems invitro would be exposed and the effects determined at once." Equipment list included. Oak Ridge National Laboratory Letter of Alexander Hollacnder APPLIDIX 3.2.4.5 It is intended that this study will consist of: a) Study of vascular and other changes in methological preparations obtained thr ughout the radiation experiment and studied in the U.5.; and b}) Studies of the chemical constituents of the clotting mechanism in plasma frozen on the spot and transported to the Neval Medical Research Institute for assay. This procedure is proposed because of the claborate equinmen’ needed for detailed studies of blood clotting; and because of too AFiTMDIXES : Be 2e4e ds Be ead dt} 3.264 6 3 204.35 3 . 20460 4
