The purpose of this study was to compare among dysplasia of oral, uterine cervix and bronchus. Using a computer cytomorphometry cell measurement program, the study was based on a retrospective review of smear cases diagnosed with dysplasia of oral, bronchial and uterine cervix, from 2002 to 2010. For 50 70 cells from each lesion, nuclear (N) and cytoplasm (C) variables were assessed: area (A), ...

Tabanus pseudonebulosus, new species, is described based on 217 female specimens and 5 males collected in Venezuela (Guarico, Aguaio, Santa Elena, and Palmarito) and in Brazil (Parcí: Santana do Araguaia, Serra das Andorinhas in São Geraldo do Araguaia, Serra Norte Carajás and Gorotire; Amazonas: Canutama; Mato Grosso do Sul: Corumbá), mostly in open vegetation, scrub forest and in rocky enviro...

Morphometrical data of pronotum, elytra, and total length of adult males and females of a Gratiana spadicea population from southern Uruguay are given. Descriptions and illustrations of aedeagus and spermatheca are provided for the first time. Females were significatively larger than males in total length. The coefficient of variation of the aedeagus measures ranged from 3.7% to 7.7%, and those...

A traumatically ruptured spleen is regarded as a proper control in many histological and immunological studies on the human spleen. This paper compares spleens that ruptured due to trauma and spleens which were removed during surgery in patients without splenic pathology. Based on a histological, morphometrical, and immunohistochemical description of the control spleens it is shown that the tra...

This study evaluated the development and the involvement in sudden perinatal and infant death of the medullary hypoglossal nucleus, a nucleus that, besides to coordinate swallowing, chewing and vocalization, takes part in inspiration. Through histological, morphometrical and immunohistochemical methods in 65 cases of perinatal and infant victims (29 stillbirths, 7 newborns and 29 infants), who ...

We report a case of the Werdnig-Hoffmann disease in a 4-month-old male infant. The morphological study revealed perimysial fibrosis, variability in the size of muscle fibers, absence of target fibers, few central nuclei and normality in vessels, nerves and neuromuscular junctions. The morphometrical examination showed the existence of normal-sized and atrophic fibers in both fibrillar types, as...
