title: [Study on the detoxification of alcohol extracts from orientvine and its effective component on withdrawal syndromes of morphine].
abstract: OBJECTIVE
  To observe the effect of alcohol extracts from orientivne and its effective component sinomenine on withdrawal syndromes and neurotransmitter of morphine-abstinent mice and on intracellular calcium level in morphine-dependent neuronal-cells line. To study the detoxification of alcohol extracts from orientvine and sinomenine on morphine-dependent animal and explore the mechanism of its effect.
  
  
  METHODS
  The effect of alcohol extracts from orientivne and sinomenineon on abstinent syndromes was observed by experiment study on morphine-dependent ex vivo ileum from guinea pigs and morphine-dependent mice. The morphine-dependent model mice were established by injection on dosage increasing by degrees. The hypothalamic monomine neurotransmitters such as NA, DA, 5-HT were tested by fluorospectrophotometry. Morphine-dependent cell line was established by administering morphine at different doses into the culture medium. The cells were stained with fluo-3 and the intracellular calcium level was measured by flow cytometry.
  
  
  RESULTS
  Alcohol extracts from orientvine and sinomenine could alleviate withdrawal contractile response of morphine-dependent ex vivo ileum from guinea pigs and withdrawal syndromes of morphine-dependent mice, decrease the concentration of the neurotransmitters, and elevate the intracellular calcium level and inhibit the decreasing of Ca2+ induced by naloxone.
  
  
  CONCLUSIONS
  Alcohol extracts from orientvine and sinomenine have some effects on withdrawal syndromes which may be related to inhibiting neurotransmitters and the regulation of intracellular calcium concentration.
