When you open a brokerage account, you have to pick between a so-called cash and margin account type. A cash brokerage account is one that requires you to deposit cash and securities, in full, by settlement, in order to engage in transactions. The brokerage firm won't lend you any money.
Extravasation is the leakage of a fluid out of its container. In the case of inflammation, it refers to the movement of white blood cells from the capillaries to the tissues surrounding them (leukocyte extravasation), also known as diapedesis. In the case of malignant cancer metastasis it refers to cancer cells exiting the capillaries and entering organs. It is frequently used in medical contexts, either referring to urine, or to blood. More specifically, it can refer to: Extravasation (intravenous)
Tissue damage from extravasation depends on the concentration of the drug in the tissue. Therefore, the best extravasation treatment is for the medical staff to be vigilant and assess an infusion of a vesicant drug every 15-20 minutes or so. Even under those circumstances, extravasation can occur. If the vesicant drug that extravasates is a vinca alkaloid, warm packs are often applied to to the affected areas. The presiding physician is notified immediately of the extravasation, and should be told of the vesicant drug and the concentration given.
