This study was performed to evaluate the effect of 6-week treatment with Uk
rain in doses of 0.3, 1.5 and 3.0 mg/kg i.v. on the morphological and bioch
emical parameters of peripheral blood and morphology of body organs in rabb
its. Ukrain application did not change the body organs and total body weigh
t The drug did not affect biochemical parameters of peripheral blood, excep
t for a minor reduction in the fetal plasma level and increases in serum ur
ic acid and urea indicating enhanced catabolism of proteins. The peripheral
erythrocyte and leukocyte counts were not altered, whereas the percentages
of lymphocytes, monocytes, and eozynophils were increased after higher dos
es of Ukrain. An increase in rod neutrophils and a decrease in the percenta
ge of segmented neutrophils were also noted. These observations indicate a
lack of organ toxicity following long-term treatment with Ukrain.
