Fertirelina CAS:38234-21-8

Ürün Açıklaması:

Fertirelin is a synthetic luteinizing hormone-releasing hormone (LH-RH) analogue, and it is a potent LHRH agonist. After a transient increase, continuous administration results in downregulation of LH and FSH levels followed by a suppression of ovarian and testicular steroid biosynthesis.

Fertirelin was administered at the beginning of the protocol followed 7 days later by 500 μ G cloprosterol. Two days later, a second dose of fertirelin was given and AI performed 16-19 h later regardless of the incidence of behavioral oestrus. The conception rate did not differ between the 50 μ G fertirelin group (61.1%; N = 72) and the 100 μ G group.

Applications:

Mainly has a strong angiotensin II vasoconstriction and increase in blood pressure. The mechanism is:

1. So that the body arteriole smooth muscle contraction, increased peripheral resistance;

2. So increase the release of adrenal aldosterone, causing sodium retention, increased blood volume;

3. Directly contribute to renal tubular sodium and water reabsorption;

4. So the brain central nervous sympathetic vasoconstrictor activity, causing increased peripheral vascular resistance;

5. Stimulate the adrenal medulla to release epinephrine and norepinephrine.
