[Contrast sensitivity in amblyopia].

The contrast sensitivity function for sinusoid gratings of various spatial frequencies was determined for both eyes of 21 cases with unilateral amblyopia. The CSF of all amblyopic eyes except one was reduced in comparison with the non-amblyopic eye of the same person. The CS curve was depressed, especially with the middle and high spatial frequencies. The cut-off high frequency shifted toward to the left, as was the peak sensitivity. The changes in CSF with respect to different degrees of amblyopia, and the possible errors that could be made during the examination were also discussed.

[Endocrine cells in gastric carcinoma].

A few endocrine cells were observed in 7 of 16 specimens of gastric carcinoma studied by electronmicroscopy. They were closely mixed with other types of tumor cells infiltrating into the stroma. Some endocrine cells contained both neuroendocrine and mucous granules. This conforms well to the hypothesis that the endocrine cells as well as other types of tumor cells in gastric carcinoma, originate from the endoderm. The endocrine cells and other varieties of tumor cells were found in both intestinal and diffuse types of gastric carcinoma. The heterogeneity and histogenesis of gastric carcinoma are discussed.
