Male Sprague Dawley rats received a single intraperitoneal dose
of BCNU in experiments designed to measure biochemical changes associated with the pulmonary toxicity described for this agent. Changes in
serum and lung lavage angiotensin converting enzyme (ACE) activity
were measured to detect changes in pulmonary endothelial cell integrity. Alpha-1-proteinase inhibitor...
Previous investigation showed that 20 mg/kg BCNU
caused inhibition of sulfobromophthalein (BSP) excretion
and inhibited bile salt independent bile flow (BSIF) in
rats by 48 h after treatment (Hoyt, 1984).
The present investigation demonstrated that BCNU
inhibited the canalicular step in the excretion of BSP.
This was indicated by the...
