title: Studies on djenkol bean poisoning (djenkolism) in experimental animals.
abstract: Djenkolic acid was extracted from djenkol beans with 70% ethanol and water and was quantitatively determined by paper chromatography. Djenkol beans contained 0.3-1.3 gm% djenkolic acid and about 93% of this acid occurred in the free state. The toxicity of djenkol beans was studied in 5 rhesus monkeys, 9 albino rats and 22 mice fed with 70% ethanol extracts. The total urinary output decreased. There was an increase in specific gravity of the urine during the period of feeding monkeys with djenkol beans. Urinary samples of the experimental animals were turbid and contained some red cells, white cells, epithelial cells, albumin and amorphous particles. One of 22 mice excreted sharp needle-shaped crystals in the urine on day 3 after feeding. Histological examination of kidneys of rats and mice showed mild to severe acute tubular necrosis with some glomerular cell necrosis.
