Passive smoking affects the child memory

A recent experimental study demonstration, passive smoking may the varying degree affect the child to study the memory ability. This research conclusion is after uses the diving platform experiment to examine under the passive smoking environment mouse's study memory ability change situation to obtain. The diving platform experiment is examines the animal study and the memory function commonly used method. The diving platform incubation period length and wrong number of times how many is observes the animal study and the memory ability target. The diving platform incubation period is short, indicated the animal responds quickly; Wrong number of times few, indicated the animal learning capability is strong. Carries on in them in the experiment, altogether selected 40 male female to be half and half the experimental mouse, stochastically divided into the comparison group, the low monitoring team, center the monitoring team and the high monitoring team, and separately put in the latter 3 groups of mice in the contamination cabinet, separately attracted 1, 2, 4 with the automatic passive plant for smoke absorption, passively smoked the speed approximately is 1/10 minutes, attracted the latter 10 minutes from to dye in the cabinet to take out the mouse, the freedom eats food, 1/day, continuously 7 days; But compares the group mouse freely to eat food, does not make any processing. The comparison group and the experimental group mouse puts in the bottom of a chest after 7 days for the circular telegram copper grid, the box internal installation has in the rubber reflection box, passes carries on the diving platform experiment by the electricity pulse. Result passive smoking is high, center, the low 3 monitoring teams mouse, in has not had in the situation which the whole body affects, the diving platform incubation period lengthens, compares with the comparison group has 显著性 the significance (P < 0.05), also the passive smoking group's smoking quantity and the diving platform incubation period logarithm has the correlational dependence, indicated passive smoking may harm mouse's study and the memory ability. In in the weight mouse memory ability second diving platform experiment, the experiment compares the group mouse wrong number of times to compare the first diving platform remarkable reduction, indicated the mouse has the certain memory ability to the electric shock; When passively smokes the group mouse second diving platform tests, its wrong number of times with the first diving platform experiment compares not obviously reduces, namely to the electric shock non- memory ability, indicated passive smoking may affect the mouse memory ability. According to the expert which is engaged in this research introduced, smoking harm health already common knowledge. In recent years the passive smoking harm also day by day received people's attention. But the people understood mostly is passive smoking may cause system disease or the function disorder and so on respiratory system, cardiovascular system, digesting system, nervous system, but also may affect the study and the memory ability regarding passive smoking actually very little causes the people enough to take. In order to let the children study and the memory ability does not receive affects, please swear off smoking not the good custom, but also a child smokeless harm life and learning environment.
