Oxytocinase is a type of enzyme that metabolizes the endogenous neuropeptide, oxytocin. [1] The most well-characterized oxytocinase is leucyl/cystinyl aminopeptidase, [1] [2] which is also an enkephalinase. Other oxytocinases are also known.
An intravenous infusion of oxytocin is used to induce labor and to support labor in case of slow childbirth if the oxytocin challenge test fails. Whether a high dose is better than a standard dose for labor induction is unclear. It has largely replaced ergometrine as the principal agent to increase uterine tone in acute postpartum hemorrhage.
Oxytocin is a peptide hormone and neuropeptide normally produced in the hypothalamus and released by the posterior pituitary. [4] Present in animals since early stages of evolution, in humans it plays roles in behavior that include social bonding, love, reproduction, childbirth, and the period after childbirth.
It is released in response to an increase in oxytocin levels in the uterus, and stimulates both luteolytic activity and the release of oxytocin. [6] Because PGF 2α is linked with an increase in uterine oxytocin levels, there is evidence that PGF 2α and oxytocin form a positive feedback loop to facilitate the degradation of the corpus luteum.

The combination of dopamine, serotonin and oxytocin is already pretty dreamy, but the brain takes that natural high to the next level when you reach the big O by releasing endogenous (i.e., made ...
The process occurs as follows: in some hypothalamic cells there are osmoreceptors which respond to hyperosmolality in body fluids by signalling the posterior pituitary gland to secrete ADH. [6] This keeps serum sodium concentration – a proxy for solute concentration – at normal levels, prevents hypernatremia and turns off the osmoreceptors. [7]
Cortisol levels rise slowly over time and take a while to return to base level, indicating that cortisol is more associated with chronic stress levels. [12] Alpha amylase, on the other hand, spikes quickly when confronted with a stressor and returns to baseline soon after the stress has passed, making salivary amylase measurement a powerful ...
Many factors can limit the accuracy of the test including edema, temperature, inflammation, medications, and stress. In addition for the measurement to be normal, all parts of the oxygenation pathway must be functioning: the lungs must be able to oxygenate the blood, the heart must be able to pump the blood, and a patent artery must be able to ...
