of erythrocytes, haemolysis and enlargement of lymph glands. A nontoxic dose of abrin (1.25 mcg/kg body weight), isolated from the seeds of redvar., exhibited a noticeable increase in antibody-forming cells, bone marrow cellularity and alpha-esterase-positive bone marrow cells.
Oral administration of agglutinins, isolated from the seeds, is useful in the treatment of hepatitis and AIDS.
Theseed extract exhibited antischistosomal activity in male hamsters.
The methanolic extract of seeds inhibited the motility of human spermatozoa.
