M. Humiczewska et al., THE EFFECT OF THE POLLEN EXTRACTS QUERCITIN AND CERNITIN ON THE LIVER, LUNGS, AND STOMACH OF RATS INTOXICATED WITH AMMONIUM FLUORIDE, Folia Biologica, 42(3-4), 1994, pp. 157-166
Quercitin and Cernitin are not in themselves toxic to rats. When admin
istered at the time of intoxication of the animals with ammonium fluor
ide, they reduced the noxious effects of the toxic agent in the liver
and lungs. It is suggested that Quercitin and Cernitin might play a pr
otective role during prolonged exposure to ammonium fluoride. Neither
ammonium fluoride nor Quercitin or Cernitin seem to exert any effect o
n the stomach.
