[Investigations on combined injuries, 24th communication: response of blood circulation and respiratory function in mice upon whom was inflicted whole-body irradiation in combination with open skin wounds (author's transl)]. 1979

H Sedlmeier, and K Lehner, and K Werdan, and O Messerschmidt

Combined injuries were inflicted upon NMRI-mice, hurting each with an open skin wound subsequent to sublethal exposition to X-rays. Lethality among animals with combined injuries was between 40 and 60%, while animals only irradiated and those with only a skin wound had lethalities between 10 and 20% and 0%, respectively. Blood circulation and respiration of animals injured with combined lesions were studied in an attempt to understand the cause of the high lethality in this group. The blood volume and the oxygen transport capacity were drastically reduced in animals with combined injuries as compared to those in animals only irradiated, although plasma volume, vascular permeability and distribution of the blood volume remained similar in both groups. Analyses of gases and acid/base composition of blood revealed neither respiratory nor metabolic acidosis. These findings indicate that combined injuries hardly impair blood circulation and respiratory function.

UI MeSH Term Description Entries
D008297 Male Males
D011829 Radiation Dosage The amount of radiation energy that is deposited in a unit mass of material, such as tissues of plants or animal. In RADIOTHERAPY, radiation dosage is expressed in gray units (Gy). In RADIOLOGIC HEALTH, the dosage is expressed by the product of absorbed dose (Gy) and quality factor (a function of linear energy transfer), and is called radiation dose equivalent in sievert units (Sv).

D012119 Respiration The act of breathing with the LUNGS, consisting of INHALATION, or the taking into the lungs of the ambient air, and of EXHALATION, or the expelling of the modified air which contains more CARBON DIOXIDE than the air taken in (Blakiston's Gould Medical Dictionary, 4th ed.). This does not include tissue respiration ( Breathing

D001810 Blood Volume Volume of circulating BLOOD. It is the sum of the PLASMA VOLUME and ERYTHROCYTE VOLUME. Blood Volumes,Volume, Blood,Volumes, Blood
D002199 Capillary Permeability The property of blood capillary ENDOTHELIUM that allows for the selective exchange of substances between the blood and surrounding tissues and through membranous barriers such as the BLOOD-AIR BARRIER; BLOOD-AQUEOUS BARRIER; BLOOD-BRAIN BARRIER; BLOOD-NERVE BARRIER; BLOOD-RETINAL BARRIER; and BLOOD-TESTIS BARRIER. Small lipid-soluble molecules such as carbon dioxide and oxygen move freely by diffusion. Water and water-soluble molecules cannot pass through the endothelial walls and are dependent on microscopic pores. These pores show narrow areas (TIGHT JUNCTIONS) which may limit large molecule movement.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
