The Effect of Hypoxia O N Succinate Metabolism I N M a N a N D T H E Isolated Perfused
نویسندگان
چکیده
1 . A marked rise in blood succinate was shown to occur in severely hypoxic patients. 2. A similar effect could be produced in the perfusate of the isolated perfused canine liver subjected to hypoxic hypoxia; in addition, tissue concentrations of succinate in the perfused liver progressively rose during hypoxia. 3. The elevation of succinate concentrations during hypoxia is partly due to reversal of the oxidative pathway from succinate to oxaloacetate. 4. A permeability barrier to succinate and fumarate exists between their locations within the cell and the circulation. 5. The permeability barrier to succinate but not to fumarate is broken down during hypoxia.

متن کاملThe Role of Anion Exchanger on Pulmonary Vascular Response to Sustained Alveolar Hypoxia in the Isolated Perfused Rabbit Lung
Background: Some respiratory diseases may induce alveolar hypoxia thereby hypoxic pulmonary vasoconstriction (HPV). However, the mechanisms of this physiologic phenomenon are not fully understood. This study was the first to investigate the role of anion exchanger in sustained HPV.Methods: Experiments were performed in the isolated perfused rabbit lung. After preparation, the lungs were divided...
متن کاملOn the Associated Primes of the generalized $d$-Local Cohomology Modules
The first part of the paper is concerned to relationship between the sets of associated primes of the generalized $d$-local cohomology modules and the ordinary generalized local cohomology modules. Assume that $R$ is a commutative Noetherian local ring, $M$ and $N$ are finitely generated $R$-modules and $d, t$ are two integers. We prove that $Ass H^t_d(M,N)=bigcup_{Iin Phi} Ass H^t_I(M,N)...
