Educação pode mudar sua vida

Cigarette smokers who are having trouble quitting because of nicotine’s addictive power may some day be able to receive a novel antibody-producing vaccine tohelp them kick the habit.
The average cigarette contains about 4,000 differentchemicals that  — when burned and inhaled — cause the serious health problems associated with smoking. But it is the nicotine in cigarettes that, like other addictive substances, stimulates  rewards centers in the brain andhooks smokers to the pleasurable  but dangerous routine.
Ronald Crystal, who chairs the department of genetic medicine at Weill-Comell Medical College in New York, where researchers are developing a nicotine vaccine, said the idea  is to stimulate the smoker’s immune system to produce antibodies  or immune proteins to destroy the nicotine molecule before it reaches the brain.

Muitas pessoas tentam parar de fumar, mas fracassam e sucumbem ao vício. Na tentativa de ajudar os fumantes,pesquisadores da Weill-Comell Medical College estão  desenvolvendo uma vacina que
a) diminua o risco de o fumante se tornar dependente da nicotina.
b) seja produzida a partir de moléculas de nicotina.
c) substitua a sensação de prazer oferecida pelo cigarro.
d) ative a produção de anticorpos para combater a nicotina.
e) controle os estímulos cerebrais do hábito de fumar.
