An isolated perfused rat lung preparation.
An isolated perfused rat lung preparation (IPL) is described and its physiologic status is evaluated. The evaluation includes light and electron microscopy after perfusion and estimations of substrate utilization. ATP content, lactate production, and incorporation of glucose carbons into lipids and CO2. It is concluded that the IPL is useful for short-term metabolic and physiologic experiments ...
متن کاملSEQUESTRATION OF LEUKOCYTES BY THE ISOLATED PERFUSED RAT LUNG
The sequestration of rat leukocytes and bone marrow cells by the lung vasculature was studied using an isolated perfused rat lung preparation. The passage of latex particles of 7.6 µm in diameter and non-hematopoietic cells through the lung blood vessels was also studied. Leukocytes and bone marrow cells were reversibly sequestered from circulation, whereas, latex particles and non-hematop...
متن کاملThe effect of mono(2-ethylhexyl)phthalate on an isolated perfused rat heart-lung preparation.
Di(2-ethylhexyl)phthalate (DEHP), the plasticizer used in the biomedical production of blood storage bags, hemodialysis systems, cardiopulmonary bypass (CPB) circuitry, and intubation tubes, is extracted from the plastic material when it comes into contact with biological fluids and is converted to its principal metabolite, mono(2-ethylhexyl)phthalate (MEHP). We have shown that MEHP causes card...
متن کاملAnalysis of ET-A and ET-B receptors using an isolated perfused rat lung preparation.
AIMS AND METHODS The pulmonary and vascular effects of endothelin-1 receptor activation were studied in isolated perfused and ventilated lung preparations from rat. The responses to endothelin-1 (ET-1) and the endothelin B (ET(B)) receptor agonist sarafotoxin 6c (S6c) were characterized using the endothelin A (ET(A))-receptor antagonist FR 139317, the ET(B)-receptor antagonist BQ 788 and the co...
متن کاملLactate production in isolated perfused rat lung.
The ability of the isolated perfused rat lung to produce lactate under aerobic and hypoxic conditions has been studied. The lung has been found capable of producing lactate at a rate of 53 mumol/g dry wt per h in the presence of as great as 1 mM extracellular lactate under aerobic conditions. Essentially 100% of the lactate synthesized was derived from [U-14C]glucose. When hypoxic, the rate of ...
