The effectiveness of the blood substitute neo red cells (NRC) on hemorrhagic shock was evaluated in dogs. Shock was induced by bloodletting, and NRC was infused immediately until the dogs recovered from shock; the process was repeated 3 times (mild shock), or NRC was infused after shock was maintained for 30 min, and the process was repeated 3 times (severe shock). In mild shock, NRC with low viscosity reduced the peripheral vascular resistance and increased the cardiac index. However, in severe shock, only a slight decrease in the peripheral vascular resistance and no increase in the cardiac index were observed. In severe shock, the total oxygen consumption increased, but red blood cells or plasma did not change the oxygen transport and did not meet the increased oxygen demand. However, the NRC increased the oxygen transport and supplied the increased oxygen demand. In mild shock on the other hand, no increase was observed in the total oxygen consumption or the oxygen transport.

D004337 Drug Carriers Forms to which substances are incorporated to improve the delivery and the effectiveness of drugs. Drug carriers are used in drug-delivery systems such as the controlled-release technology to prolong in vivo drug actions, decrease drug metabolism, and reduce drug toxicity. Carriers are also used in designs to increase the effectiveness of drug delivery to the target sites of pharmacological actions. Liposomes, albumin microspheres, soluble synthetic polymers, DNA complexes, protein-drug conjugates, and carrier erythrocytes among others have been employed as biodegradable drug carriers. Drug Carrier
D006454 Hemoglobins The oxygen-carrying proteins of ERYTHROCYTES. They are found in all vertebrates and some invertebrates. The number of globin subunits in the hemoglobin quaternary structure differs between species. Structures range from monomeric to a variety of multimeric arrangements. Eryhem,Ferrous Hemoglobin,Hemoglobin,Hemoglobin, Ferrous
