Abstract
This disclosure relates to pectin-based polymer compositions and methods of use thereof to cover, protect, and seal injuries, e.g., surgical wounds, in a mesothelial tissue. The methods include obtaining a bioadhesive pectin-based polymer composition including a complex of high-methoxyl pectin (HMP) and carboxymethylcellulose (CMC) in a ratio from about 10 to 1 to 1 to 10 by weight; applying the composition to an injured mesothelial tissue; and applying pressure for at least one minute to enable the composition to bind to the mesothelial tissue.
