Albumin as one-way transport vehicle into sites of inflammation
Abstract:
Intravenously injected Evans blue combines with albumin. The resulting complex appears in the inflammatory exudate that collects in Sephadex G 200 subcutaneously injected into rats. A comparison between the concentrations of albumin and Evans blue in the blood and in the inflammatory exudate shows that the life-span of albumin in the Sephadex is drastically reduced. After decomposition of albumin, the combined Evans blue is liberated, accumulates in the Sephadex and, after 24 h, attains concentrations higher than in the blood. The experiment is a plausible model for transport and deposition of albumin-bound drugs into and at sites of inflammation.

The typical wound exudate is odorless, transparent, straw-colored, thin, and watery. Exudate, however, can differ depending on the state of wound healing. Likewise, the exudate's...

Drug Binding to Blood Components
HSA is the most abundant plasma protein and is vital in drug binding. It contains distinct drug-binding sites, with different drugs exhibiting affinity for specific sites. There are three main drug-binding domains for HSA: sites I, II, and III. These domains are further...
