A new study recommends that mothers should more often show affection to babies and their baby. Compassion and caring mother gives the immune system early in life of children will help prevent children from drug addiction as an adult.
Researchers from Duke University and the University of Adelaide in Australia, found the attention on early childhood brain can alter the immune response of children. In studies on rats, they found rats who obtain most of the touch of their mothers had higher levels of a molecule called Interleukin-10.
This means they are better able to resist the temptation of narcotics and illicit drugs later in life.
During the study researchers used a technique called ‘paradigm of handling,’. Little rats are removed from the cage holding them for 15 minutes and then returned. “When their baby return, the mother inspect, clean and care for its baby,” said Professor Bilbo, according to the Daily Mail.
Whereas in the control group, no rat babies were separated from its mothers. However, there are a few mother rats who naturally gave more attention than others.
Later during the two space preference test, rats babies will receive a dose of morphine when it enters a room and salt on the other side. Over the next four weeks, the rats returned to the two sides three times a week for five minutes. “Although initially it showed to prefer morphine space, over time their desire extinguished,” said Professor Bilbo.
Eight weeks after contact with morphine, rats were given each a small dose of morphine and then returned to the room. Control rats were more likly to spend time in the room given morphine while those given does not have a clear preference.
This study is first to show that morphine causes the response of molecules in a specific cell in the center of the circuit arrangement are identified as drug addiction. IL-10 fights the inflammation and the desire to use drugs.
And, the brain of rats that had a touch of their mothers most often have more active genes that produce IL-10 four times more than control rats.
Scientists chose rats because these animals have the same vulnerability as humans against drug addiction. Parts of the brain and the genes that regulate the same addiction. The team will next see the long-term effects of stress on immune response of the brain stem of children.
