ABSTRACT

Objective To evaluate the efficiency of injection of colloidal chromic phosphate 32 P cavity in rats with rheumatoid arthritis.Methods Collagen induced arthritis (CIA) was produced in Sprague Dawley rats.After one week immune,the right post ankle was given colloidal chromic phosphate 32 P intra articular injection.Severity of arthritis was observed by the left to right diameter of the right post ankle joint,the volume of right post paw and the arthritic index.Results The group treated with colloidal chromic phosphate 32 P intra articular injection developed milder arthritis compared with control CIA group after 6 weeks.The left to right diameter of the right post ankle joint was (3 96?0 05) mm of the colloidal chromic phosphate 32 P intra articular treated group compared with (4 11?0 08) mm of the control CIA group ( P
