Light and electron microscope study of osmotically induced tumor necrosis.
Necrosis of 1.5-cm Walker 256 tumors was produced by injecting a strongly hypertonic solution of glucose in and around the growths and by delaying resorption of the solution with serotonin, given s.c. at a distance. The morphological changes occurring in 13 tumors were followed by light and electron microscopic analysis of samples taken 0.25, 0.5, 1, 1.5, 3, and 5 hr after treatment. The 0.25-h...
متن کاملLight and Electron Microscope Studies of Mycobacterium- Mycobacteriophage Interactions Ii. Electron Microscope Studies'
In the previous experiments (Takeya et al., 1959b) the interactions of Mycobacterium avium with mycobacteriophage B-1 were studied by cyttilogical techniques, and the latent period of the B-1 phage infecting the host cell was determined under the conditions used in the preparation for electron microscopy. The present paper deals with the results of experiments on the interactions of mycobacteri...
متن کاملLight and electron microscope studies of Mycobacterium-mycobacteriophage interactions. I. Light microscope studies.
Several mycobacteriophages active against mycobacteria have been isolated by Takeya and Yoshimura (1957) using the soil-enrichment technique. Among these phages, B-1 was found to have the broadest host range including virulent strains of tubercle bacilli. In the present investigation the interactions between mycobacteriophage B-1 and its host strain Mycobacterium avium were examined under the l...
متن کاملLight and electron microscope of grass carp (Ctenopharyngodon idella) organs following exposure to various sublethal concentrations of diazinon
Histopathological effects of different sublethal concentrations (1, 2 and 4 mg/l) of diazinon, an organophosphorus pesticide, on gill, liver, spleen and kidney of grass carp (Ctenopharyngodon idella) were studied after 1, 7, 15, 30 and 45 days post-exposing fishes weighting 850 ± 155 g to the toxicant for 12 hours at 18-22ºC. In addition, tissues of nostril were examined for transmission electr...
