[Study on the pelvic stomata and computer image processing].
A medical image processing system attached to electron microscope was used to study the pelvic stomata of fetuses quantitatively. Two kinds of the mesothelial cells were found on the pelvic peritoneum of fetuses and mice, i.e. flattened and cuboidal cells. The pelvic stomata, arranged in clusters, only were located among the cuboidal cells with skewed distribution. Discrete scale of the pelvic stomata area varied greatly. The average area of a stoma was 10.00 +/- 9.44 microns2. Coefficient of variation was 94.40. Standard deviation and standard error were 9.44 and 0.98, respectively. Most of the pelvic stomata present were 1.34 microns2 to 32.11 microns2, and the maximum and the minimum areas of stomata were 43.4 microns2 and 0.8 micron2. The average percentage of the pelvic stomata was 7.2%.
