大家别靠近微波炉看里面,伤眼睛。
Abstract: The cataractogenic effects of the microwave oven on rat eyes were investigated
histologically. Twenty-one adult Wistar-Albino rats (2-2.5 months old) were divided into
three groups (n = 7): a control group (sham-exposed) and two experimental groups. The experimental
rats were confined in special cages and placed next to the closed door of a microwave
oven. The first experimental group was given 15 minutes of daily exposure and the second,
30 minutes, for I month. Biomicroscopic examination detected no pathological damage
to the lens in the experimental rats. Histologically, there was a lens of single-layered epithelium
in the control group. In the first experimental group, there was slight pleomorphism in
the superficial epithelial cell contours and vacuolizations in the lens fibers; the second experimental
group, had pronounced pleomorphism and pyknosis of the nuclei in the superficial
epithelium. Some of the superficial epithelial cells had disappeared and were histologically
observed as acellular areas. Single-layered epithelium became disorganized and formed multilayered
epithelial groups in the superficial epithelium. Vacuolization was more prominent
in this group. Personal exposure from microwave ovens is generally minimal because of the
rapid decrease in power density with distance. Microwave oven users do not normally stand
as close to the oven as the rats in our study were placed; therefore, it is difficult to suggest
that microwave ovens always have cataractogenic effects on human eyes. Jpn J Ophthalmol
