Pre- and post-partum plasma amine oxidase differences in the rhesus monkey (Macaca mulatta)
Experientia
|September 15, 1976
Summary
Plasma amine oxidase activity significantly increased in rhesus monkeys during the extended postpartum period compared to pregnancy. This finding highlights metabolic changes after childbirth in these primates.
Area of Science:
- Biochemistry
- Primate Physiology
- Reproductive Biology
Background:
- Plasma amine oxidase plays a role in various physiological processes.
- Hormonal and metabolic shifts occur during and after pregnancy.
Purpose of the Study:
- To investigate changes in plasma amine oxidase activity during pregnancy and the postpartum period in rhesus monkeys.
- To compare enzyme activity between pregnant, postpartum, and non-pregnant states.
Main Methods:
- Blood samples were collected from 10 rhesus monkeys during pregnancy and an extended postpartum period.
- Plasma amine oxidase activity was measured using established biochemical assays.
- Activity levels were compared to those of non-pregnant control monkeys.
Main Results:
- Plasma amine oxidase activity was 23.4 nmol/ml/h during pregnancy.
- Activity increased to 49.5 nmol/ml/h during the extended postpartum period.
- Significant differences in enzyme activity were observed in the extended postpartum period compared to controls.
Conclusions:
- Plasma amine oxidase activity shows a marked elevation in the postpartum period in rhesus monkeys.
- These findings suggest significant metabolic adaptations occurring after childbirth in this species.
- Further research is warranted to elucidate the specific role of amine oxidase in postpartum recovery.
