The effect of undernutrition on spinal ganglion nerve cell size. A morphometric study on rat.

In previous investigations on rat it has been shown that prenatally instituted undernutrition leads to an irreversibly impaired calibre growth in sensory fibres of the peripheral as well as the central nervous system. A study was made on the increase in size of spinal ganglion nerve cells of normal and undernourished rats. Although the undernourished rats weighted only 50% of the controls no differences in spinal ganglion nerve cell size were found in the four age groups examined, i.e. rats 20, 60, 90 and 180 days of age.
