REFLEKS ANAK MENCIT (Mus musculus Linn.) YANG TERPAPAR MEDAN ELEKTROSTATIK SELAMA PERIODE PRA-LAHIR
To study whether electrostatic field could affect developmental behavior in animals, three groups of pregnant female mice (Mus musculus Linn.) were reared under electrostatic fields of different voltages. The first group was treated with a placebo of 0 kV/m, the second group was exposed to 6 kV/m electrostatic field while the last one was exposed to the field of 7 kV/m. Post-natal infants of each group were tested for its pivoting and righting reflex behavior. In pivoting tests, the infant mice
... ts, the infant mice placed on a sloping board started with its head pointed down the slope. The pivoting was timed when the mice turn its head up the slope. Two types of righting were tested, surface and mid air. For surface righting tests, mice placed on their back, on a surface, and the righting time by themselves was recorded. Mid air righting reflex were tested by dropping the mice from a height of 50 cm, if the mice landed correctly on the ground the mid air righting is counted positive. By using a linear-regression analysis model to the data resulted, the conclusion is the electrostatic field of 7 kV/m tend to reduce pivoting and righting development in infant mice.
