Histopathological Study of the Bone Marrow of Rabbit Femora with Experimentally Induced Acute Decompression Sickness : with consideration of pathogenesis of dysbaric osteonecrosis in diver's femur Kitano, Motoo 108235 キタノ, モトオ 北野, 元生 Kawashima, Mahito 108236 Hayashi, Ko 108237 Tokufuji, Shin-Ichiro 108238 Taya, Yasushi 108239 Lehner, Charles E. 108240 490 Experimental data that in an acute stage of decompression sickness (DCS) marked and extensive formation of gaseous bubbles in the sinusoids and extravascular spaces with frequent arterial and arteriolar collapse occurred in the bone marrow of the femora of rabbits is presented. Discussing the related evidence linking these observations with dysbaric osteonecrosis (DON) in divers and caisson workers, intravascular and extravascular bubble formation may cause marked elevation of intraosseous pressure resulting in arterial collapse especially of the "watershed zones" which include the weight-bearing juxta-articular area and distal shaft area of the bone marrow of human femur. Disturbance in the venous return from the bone marrow due to extensive bubble embolization of the sinusoids should accentuate the elevation of the intraosseous pressure. "* In this paper we use the term "watershed zone", which is often used in the field of Neuropathology, for the border or boundary zone between the teritories of two or more major arteries." journal article 鹿児島大学 Kagoshima University 1994-03-15 VoR application/pdf 南太平洋研究 2 14 223 231 South Pacific Study 09160752 AN10088628 https://ir.kagoshima-u.ac.jp/record/2512/files/AN10088628_v14-2_P223-231.pdf http://hdl.handle.net/10232/15577 https://ir.kagoshima-u.ac.jp/records/2512 eng open access
