Abstract
A medical composition for protuberance of epithelium, which comprises a solution comprising a polysaccharide or a medically acceptable salt thereof, wherein the solution has a viscosity of: (1) from 50 to 500 mPa·s at a shear rate of from 7.7 to 10.0 s−1; (2) from 45 to 300 mPa·s at a shear rate of from 19.2 to 20.0 s−1; and (3) from 40 to 200 mPa·s at a shear rate of from 38.3 to 40.0 s−1, when measured using a rotational viscometer at 25° C., and a syringe filled with the medical composition.
Claims11
A method for resecting epithelium, which comprises:
- administering an effective amount of a medical composition to under epithelium to thereby obtain protuberance of the epithelium;
- and
- resecting the protuberance, wherein the medical composition comprises a solution consisting essentially of hyaluronic acid or a medically acceptable salt thereof and chondroitin sulfate or a medically acceptable salt thereof wherein the medical composition has a viscosity of:
- (1) from 50 to 500 mPa·s at a shear rate of from 7.7 to 10.0 s−1;
- (2) from 45 to 300 mPa·s at a shear rate of from 19.2 to 20.0 s−1;
- and
- (3) from 40 to 200 mPa·s at a shear rate of from 38.3 to 40.0 s−1,
- when measured using a rotational viscometer at 25° C.,
- chondroitin sulfate or a medically acceptable salt thereof.
