Methods After supplementing Cr with loading dose for 1 week and maintaining dose for 1 month and 2 months in the rats, L-arginine:glycine amidinotransferase (AGAT) activity in kidney, guanidinoacetic acid (GA) contents in kidney and liver, creatine contents in kidney, skeletal muscle and serum, creatine kinase (CK) activities in skeletal.

Methods After creatine supplementing with high different doses for 4 weeks in the rats, the activities of L-arginine:glycine amidinotransferase (AGAT) and the contents of guanidinoacetic acid (GA) which is the enzymatic reaction product of AGAT in kidney and pancreas, the Cr concentrations in skeletal .

Methods: After treated with variable doses of creatine,the activities of L-arginine glycine amidinotransferase(AGAT),the concentration of guanidinoacetic acid(GA)in kidney,the concentration of creatine in skeletal muscles and serum in the exercise and control rats were measured.

Three amorphous zirconium mixed phosphate phosphonate supports Zr(HPO 4) 2- x ·(O 3P(CH 2) 2NRR 1) x ·H 2O(R=H or (CH 2) 2CN; R 1=H, C( NH)NH 2 or (CH 2) 2CN) and palladium catalysts supported on them were prepared from 2 guanidoethylphosphonic acid, 2 aminoethylphosphonic acid, and N,N (biscyanoethyl)aminoethylphosphonic acid with zirconium oxychloride and phosphoric acid, respectively.
