Abstract: A composition containing a high concentration of a biologically active drug and a method for the use thereof to reduce vial breakage in a lyophilization process are disclosed.

Abstract: The invention relates to compositions comprising adducts of activated polysaccharides with biologically active growth hormones, somatomedins, growth factors and biologically active fragments. The invention also relates to a method for increasing and maintaining increased levels of these biologically active molecules in the blood of treated animals for extended periods of time, increasing weight gains in animals, and increasing milk production of lactating animals by the administration of a composition of the invention.

Abstract: A method for the preparation of a polyetherthioether copolymer glycol represented by the formula:H--OC.sub.2 H.sub.4 SC.sub.2 H.sub.4 --.sub.x --OC.sub.4 H.sub.8 --.sub.y OHwherein the mole ratio x/y is in the range of about 45:55 to 60:40, respectively. More specifically, a method for the preparation of a copolymer of thiodiethanol and 1,4-butanediol wherein the mole ratio x/y is about 50:50. Also, the copolymers produced thereby and polyurethane elastomers produced therefrom, particularly those produced from the 50:50 copolymer, and to their use in solid tires having improved dynamic mechanical properties.
