AN ELECTRON MICROSCOPIC STUDY ON PERITUBULAR WALL OF HUMAN CRYPTORCHID

An Electron Microscopic Study on the Toad

In spite of numerous investigations, the nature and function of the subcommissural organ (SCO) located beneath the posterior commissure was not clear owing to poor staining methods, and for a long time this organ was regarded as one of the most mysterious organs. However, since recently a variety of special staining methods including GOMORI's chrome alum hematoxylin and other histochemical tech...

Horner's syndrome: an electron microscopic study of a human iris.

Electron microscopy was performed on the irides of a man with a history of a long standing Horner's syndrome which resulted in iris heterochromia. Comparison of his normal brown iris with the depigmented blue iris showed depletion of anterior border cells and absence of sympathetic nerve fibres. Stromal melanocyte numbers were also diminished but melanosome numbers within the residual cells wer...

Electron microscopic study of human basophils.

Electron Microscopic Study of Human Laryngeal Papillomatosis.

Sixteen biopsies of laryngeal papillomas from patients 4-21 years old, as well as tissue from scarred areas of laryngeal mucosa which previously bore papillomas, were studied with the electron microscope and compared with normal laryngeal mucosa. Tissue blocks that contained cytoplasmic bodies by light microscopy were serially sectioned for electron microscopic examination. The bodies appeared ...

Normal human lymph node cells: an electron microscopic study.

LTHOUGH AN EXTENSIVE literature has accumtilated on the electron microscopy of mammalian lymph nodes, the ultrastructure of normal nodes of human origin has received less attention. Bernhard and Granboulan1 and Granhoulan2 have reported on the ultrastructure of human lymph node cells, and recently Bernhard and Leplus have published an atlas containing electron micrographs of cells from normal a...
