Electron Microscopy of Collagen Fibrils During Cortisone Therapy of Alopecia Totalis (Technical Problems)1

Acute alopecia totalis.

From a group of 1,189 AA patients seen in our dermatology unit, thirteen (3 males, 10 females) experienced hair shedding that started profusely and diffusely over the entire scalp. They were under observation for about 5 years, histopathology and trichograms being performed in all instances. The mean age of the patients was 26.7 years. It took only 2.3 months on average from the onset of hair s...

Examination of Lung Parenchyma by Electron Microscopy

In this paper many of the principal struc­ture of the Moral Lung were studied with the help of Electron Microscopy. Detailed descrip­tion was given of Granular Pneumocytes, Membranous Pneumocytes, Macrophages, and Alveolar Capillaries. A discussion followed on the form and function of Granular Pneumo­cytes.  Acknowledgements  I am grateful to the Reza Shah Pahlavi Foundation for its generou...

Electron Microscopy of Neuroglial Fibrils of the Cerebral Cortex

The nature of neuroglial fibres, observed by light microscopy in silver and other preparations of the cerebral cortex, has for long been controversial. So has the question of whether these fibres are extracellular, intracellular, or the actual cyto-plasmic processes of glia (2, 11). In this report the absence of extracellular fibres is confirmed by electron microscopy and fibrils that are embed...
