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...

Isolation of Herpetosiphon giganteus and Ultrastructure Analysis by Electron Microscopy

Herpetosiphon giganteus is a filamentous gliding bacterium. Gliding motility is the movement of the cells over surfaces without the aid of flagella. The mechanism responsible for bacterial gliding motility has not been known and there are only a few data on Herpetosiphon giganteus. The aim of this study was to observe the ultrastructure and negative staining of isolated strains of Herpetosiphon...

The Molecular Weight of Crystalline Catalase.

In 1933 Stern (2) used the diffusion method of Northrop and Anson (3) to determine the molecular weights of purified catalase from horse liver, pig liver, cow liver, horse kidney, and cow erythrocytes. He found the average value for the molecular weight of catalase to be 68,900, and stated that the catalase molecule has a dimension similar to that of hemoglobin. In 1938 Stern and Wyckoff (4) pu...
