[en] Isotope measurements were carried out in patients receiving intra-articular injection of colloidal solution of radioactive chromium phosphate for chronic synovial exudates in knee joints. The degree of isotope escape outside the joint and its accumulation in the inguinal lymph nodes and liver were evaluated. Twenty-three joints were studied, in 9 cases some escape of the isotope from the joint and absence of accumulation in lymph nodes was observed. In the remaining 14 cases the accumulation in lymph nodes was observed, in 12 of them the amount of isotope was below 1% of the administered dose, in 2 cases was about 2%. In these cases the amount of the isotope escaping from the joint was from several to over ten per cent. In one case some accumulation of the isotope was observed also in the liver. (author)
