Fig. 3. Chemical characteristics of hydroxyethyl starch (HES) 70 (diamonds) and HES200 (squares) up to 24 h after HES infusion. (A ) Concentration (milligrams/milliliter); (B ) weight average molecular weight (Mw); (C ) number average molecular weight (Mn); (D ) molar substitution (MS); (E ) polydispersity (Mw/Mn). P values indicate the difference between HES70 and HES200 (P HES).
