title: Enzymatic activity in crude oil contaminated rats.
abstract: The activity of enzymes found in the plasma, malate dehydrogenase (MDH) and lactate dehydrogenase (LDH), and enzymes from erythrocytes, glucose-6-phosphate dehydrogenase (G-6-PDH) and catalase, was studied in rats contaminated by crude oil. Crude oil (tube fed) contamination caused a significant increase in MDH and LDH activity 96 hr after contamination while a decrease in activity was noted in 6-6-PDH and catalase. An additional contamination (1 week after the first contamination), measured 96 hr after contamination, caused a relative decrease in MDH and LDH activity while there was a contrasting relative increase in G-6-PDH and catalase activity. After a recovery period of 3 weeks the only significant change was an increase in catalase activity.
