title: [Evaluation of the protective action of diphosphonic compounds against a T-lymphocyte lesion by antilymphocyte serum].
abstract: Rabbit antilymphocyte serum (ALS) and complement were used in doses killing 50% of lymphocytes (staining with a 1% solution of trypan blue). In rosette-forming and blast-cell transformation reactions the counts of rosette forming and transformed cells were 60 and 24% respectively, as compared to those in controls. After adding 0.1 ml of 10 mM solution of potassium hydroxyethylene-diphosphonate belonging to a group of synthetic diphosphonates, the protective effect was observed shown by that the counts of rosette-forming and transformed lymphocytes did not differ from the control ones, wherein the reactions were produced with intact cells.
