In this study, myoglobin reaction kinetics is added to a proven cardiac tissue model in an effort to determine the extent of myoglobin facilitation. The mathematical model is compared to experimental pO/sub 2/ measurements taken from an isolated perfused cat heart preparation. The model is based upon the Krogh cylinder. In the tissue region there is axial diffusion, zero-order oxygen consumption, and myoglobin kinetics. Oxygen flux leaving the capillary is represented by a concentration difference times a mass transport coefficient, meaning that the tissue is considered \"well mixed\" radially. The tissue model is called the Radially-Averaged-Axially-Distributed (RAAD) model. Formulation of the mathematical problem describing the RAAD model yields a stiff, fourth-order, nonlinear, ordinary differential equation, boundary value problem. The equation set was solved numerically using a finite difference routine on a mainframe computer. The amount of diffusion facilitation by myoglobin was estimated by observing the inlet arteriolar pO/sub 2/ for the model with and without myoglobin. The computer simulations show that myoglobin does facilitate diffusion, but only to a small extent. The change in arteriolar pO/sub 2/ was less than 1% (0.76%). The facilitation is limited due to the low concentration and low diffusability of myoglobin in tissue. This suggests that facilitation of oxygen transport is not myoglobin's main physiological function.","PeriodicalId":332563,"journal":{"name":"Proceedings of the 1995 Fourteenth Southern Biomedical Engineering Conference","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126116605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sawaguchi et al., Acta Orthop. Scand., vol. 55, p. 601-5, 1984). The hypothesis tested in the current study is that simple transverse acetabular fractures can be fixed by posterior plating alone without the need for anterior column plating or screw fixation. If so, this would reduce operative time and eliminate the difficult task of anterior screw placement or dissection for anterior plating. So the objective of this study was to compare the stability of transverse acetabular fractures fixed with posterior plating alone versus posterior plating and anterior column screw fixation, at both zero and 90/spl deg/ of hip flexion. The authors conclude that: 1. The simple transverse acetabular fractures are \"stable\" when loaded at 0/spl deg/ of hip flexion and \"unstable\" when loaded at 90/spl deg/ of hip flexion. 2. There was a statistically significant difference in the axial stiffness and the posterior displacement at the fracture site when comparing no fixation versus fixation only at 90/spl deg/ hip flexion. But there was no significant difference when comparing posterior plating alone versus posterior plate and anterior column screw fixation at both 0/spl deg/ and 90/spl deg/ of hip flexion.","PeriodicalId":332563,"journal":{"name":"Proceedings of the 1995 Fourteenth Southern Biomedical Engineering Conference","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127076853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
