High molecular weight fucan to treat fibrous adhesions and other diseases and conditions

摘要

The compositions, systems, devices, materials, and methods herein provide high molecular weight fucans. Such high molecular weight fucans can be obtained from feedstock fucan compositions or other starting or initial fucan compositions with fucans having a broad molecular weight distribution containing the desired high molecular weight zones/parts (i.e., it can be derived from high molecular weight fucans and , This starting fucan composition may or may not be crude or may be previously processed or purified). The desired high molecular weight fucan essentially has a molecular weight distribution consisting of the desired high molecular weight section/part of the broad molecular weight distribution of the starting fucan, where a significant amount of the broad molecular weight distribution at the low molecular weight end is removed, inhibited or attenuated so that all residuals are not critical.
