A light and electron microscopic study
نویسندگان
چکیده
The corneal stromal lesions of a case of lattice dystrophy that fulfilled all the clinical and histopathologic criteria of this disease were examined by light and electron microscopy. The lesions were found to consist of two distinct parts: (1) a nonbirefringent mass of disoriented filaments of approximately one-third the diameter of normal stronml collagen fibrils and (2) a second, birefringent part containing -modified stromal lamellas with highly oriented fibrils of normal diameter but increased density. These observations suggest that the normal collagen fibril separates into filaments of smaller diameter ("fibrillary degeneration").

Light and electron microscopic study of the tongue in the White-eared bulbul (Pycnonotus leucotis)
The aim of the present study was to investigate the light and electron microscopic structure of the tongue in White-eared bulbul (Pycnonotus leucotis). Six adult White-eared bulbul (3 males and 3 females) in Shahrekord district were used in the investigation. Samples of the apex, body and root of the tongue were prepared routinely for light and electron microscopic study. Results showed that th...

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...

متن کاملUsing laser scanning confocal microscopy as a guide for electron microscopic study: a simple method for correlation of light and electron microscopy.
Anatomic study of synaptic connections in the nervous system is laborious and difficult, especially when neurons are large or have fine branches embedded among many other processes. Although electron microscopy provides a powerful tool for such study, the correlation of light microscopic appearance and electron microscopic detail is very time-consuming. We report here a simple method combining ...
