Cobalt-activated acylase activity in experimental toxic liver damage

Summary
Carbon tetrachloride (CCl4) poisoning in rabbits temporarily elevated serum acylase activity. Liver acylase activity increased and persisted longer, showing no direct correlation with serum levels but correlating with other liver enzymes.
Area of Science:
- Biochemistry
- Toxicology
- Enzymology
Background:
- Carbon tetrachloride (CCl4) is a known hepatotoxin.
- Investigating enzyme activity changes in response to CCl4 poisoning is crucial for understanding liver injury.
- Co++-activated acylase is an enzyme whose role in CCl4-induced toxicity requires further elucidation.
Purpose of the Study:
- To investigate the activity of Co++-activated acylase in blood serum and liver homogenates of rabbits following CCl4 poisoning.
- To determine the temporal dynamics of acylase activity in both serum and liver post-intoxication.
- To explore potential correlations between Co++-activated acylase activity and other biochemical markers of liver damage.
Main Methods:
- Rabbits were administered varying doses of CCl4 intraperitoneally.
- Co++-activated acylase activity was measured in blood serum and liver homogenates.
- Enzyme activities of AlAT, GGTP, and LAP were also assessed.
- Data were collected over a nine-day observation period.
Main Results:
- Serum Co++-activated acylase activity showed a transient increase on the first day post-CCl4 poisoning.
- Liver homogenate acylase activity increased and remained elevated throughout the nine-day observation period.
- No significant correlation was found between serum and liver Co++-activated acylase activities.
- Serum Co++-activated acylase activity demonstrated significant correlations with AlAT and GGTP activities.
Conclusions:
- CCl4 poisoning induces distinct temporal patterns of Co++-activated acylase activity in rabbit serum and liver.
- Serum acylase activity is a short-term indicator, while liver acylase activity reflects sustained hepatic response to CCl4 toxicity.
- Co++-activated acylase activity may serve as a potential biomarker, particularly when assessed alongside other liver injury markers like AlAT and GGTP.
