Scanning electron microscopy of lichen sclerosus*
Lichen sclerosus is an acquired inflammatory condition characterized by whitish fibrotic plaques, with a predilection for the genital skin. We performed scanning electron microscopy of the dermis from a lesion of lichen sclerosus. Normal collagen fibers could be easily found in deeper layers of the specimen, as well as the transition to pathologic area, which seems homogenized. With higher magn...
متن کاملExtragenital bullous lichen sclerosus.
Lichen sclerosus is an inflammatory skin condition characterized by inflammation of the papillary dermis that leads to white scarlike plaques. It occurs classically in the genitals but also has extragenital manifestations with a variety of clinical presentations including a bullous variant. The purpose of this review is to characterize extragenital bullous lichen sclerosus, suggest that it may ...
متن کامل[Lichen sclerosus et atrophicus].
A case of lichen sclerosus et atrophicus (LSA) involving the oral mucosa is described. The lesion began in the labial mucosa with extension to the gingiva and to the skin. The frequency of occurrence of oral lesions of LSA is discussed, and a histopathologic comparison with skin lesions is made.
متن کاملScanning Electron Microscopy (SEM) analysis and biological control of Ixodes ricinus using entomopathogenic fungi
In the present study, pathogenicity of four native strains of Entomopathogenic fungus; Metarhizium anisopliae, was studied against adult stage of Ixodes ricinus. For this purpose a total number of 180 adult ticks were examined in triplicate. Thirty ticks for each strain and negative and positive controls were immersed in 2.4×107 fungal conidia/ml in vitro. Samples were incubated in separate Pet...
متن کاملScanning ultrafast electron microscopy.
Progress has been made in the development of four-dimensional ultrafast electron microscopy, which enables space-time imaging of structural dynamics in the condensed phase. In ultrafast electron microscopy, the electrons are accelerated, typically to 200 keV, and the microscope operates in the transmission mode. Here, we report the development of scanning ultrafast electron microscopy using a f...
