title: Protective Assessment of Euphorbia neriifolia and its Isolated Flavonoid Against N-nitrosodiethylamine-induced Hepatic Carcinogenesis in Male Mice: A Histopathological Analysis.
abstract: OBJECTIVE
  The aim of this study was to examine the impacts of N-nitrosodiethylamine (DENA), a potent environment carcinogen on liver tissue of mice which was attenuated by isolated flavonoid and hydro-ethanolic extract of Euphorbia neriifolia (HEEN) leaves.
  
  
  METHODS
  Carcinogenicity was induced in albino mice by a single oral administration of DENA (50 mg/kg body weight). The HEEN (150 and 400 mg/kg body weight), butylated hydroxyanisole (BHA; 0.5 and 1%) and E. neriifolia flavonoid (ENF; 50 mg/kg body weight) were estimated to examine the possible anti-cancer potential.
  
  
  RESULTS
  DENA exposed animals showed alterations in normal hepatic histo-architecture, which comprised of necrosis (N), dilated sinusoids and vacuolization of the cells. Mice treated with E. neriifolia lower (ENL) and higher (ENH) dose and ENF before intoxicated with DENA showed that the liver cells were normal, with very little necrosis (Day 31). On the other hand, BHA higher (BHAH) and lower (BHAL) dose failed to diminish the abnormalities caused by the DENA.
  
  
  CONCLUSIONS
  Results of the present study suggests that the ENH and ENF protects the hepatic tissue against DENA-induced hepatic carcinoma. The results could also be expressed in the order of ENH> ENF> ENL> BHAH> BHAL.
