Osmotherapy inhibits these channels. Vasopressin receptors activated by vasopressin are found on the basolateral membrane of the cells lining the collecting ducts of the kidneys. Aneurysmal subarachnoid hemorrhage(aSAH) results in hyponatremia which leads to water retention and antidiuretic hormone release causing increase in intracranial pressure and formation of cerebral edema. This can be prevented by administration of conivaptan, a safe FDA approved drug that treats euvolemic hyponatremia. Through the process of aquaresis, conivapten which is a vasopressin receptor antagonist improves serum sodium concentration while eliminating free water without having any negative effect on systolic blood pressure and pulse rate.

Fetal bovine serum and virus, endotoxin, haemoglobin, IgG and total protein assays. Ethical questions have been raised regarding the blood collection process due to the potential suffering caused to the fetus. Although anoxia or active slaughter could be used to induce unconsciousness or death prior to serum harvesting, exposure of live unborn calves to oxygen can cause them to gain awareness before being killed, resulting in active debate about the ethics of harvesting serum. Fetal bovine serum is commercially available from many manufacturers, and because cells grown in vitro are highly sensitive, customers usually test specific batches to check for suitability for their
