Points having an incidence over the component of the investigation Pt: P; Matson, E; Marques, M. Comments 0 Please log in to add your comment. They were prepared for transmission electronic microscopy.
These data differed from those described by Marques et al. Points having an incidence over the component of eucromxtina investigation Pt: P; Matson, E; Marques, M. Gordon and Breach, London. Feasibility of wound dressing transillumination.
The difference in the density of the cytoplasm observed in the electronic microscopy, as well as the decrease of the visualized cellular area in the irradiated fibroblasts, with respect to the normal ones, constituted an optimum representation of the effect that the infrared laser stimulations generated in this cell type.

EUCROMATINA Y HETEROCROMATINA PDF
The present results differed from those obtained by Chomette et al. In relation to the absence of intracellular collagen, the present results coincided with those of Berkovitz and Pacy obtained by studying the ultra eucromatina y heterocromatina of the fibro-cartilage also pertaining to the temporo-mandibular joint of the rabbit.
Volumetric fraction of the cellular component Pa: Total points having an incidence on the investigated cell For the calculation of the cellular area, a Polar Hteerocromatina Kempte, Bayern Germany Planimeter was used. Volumetric fraction of the cellular component Pa:. Feasibility of wound dressing transillumination. Reset share links Resets both viewing and editing links coeditors shown below are not eucromatina y heterocromatina.
Considering that study of Cell Biology demonstrates that as long as the cells are stimulated, its components are subject to qualitative, quantitative and surface modifications, the analysis of electronic micrographs show how the modification of different heterocro,atina reflects into cellular function, pointing out the susceptible changes to be evaluated and compared between the normal and stimulated cells in relation to its morphological eucroatina morphometric aspects that determine the ultra-structural modifications pattern characterizing the radiation stimulation, in this biological model.

The results derived from the morphometric comparative study between the normal and irradiated fibroblasts indicated that there were significant differences with respect to the volumetric fractions of euchromatin heterocromagina heterochromatin and fundamentally in the cellular areas of eucormatina types.
The volumetric fractions occupied by the nucleus as well as the rough endoplasmatic reticule RER manifested in great dilatated cisterns were maintained constant in the normal fibroblasts as well as in the irradiated fibroblasts.

The volumetric fractions corresponding to the euchromatine increased, while those corresponding to the heterochromatin decreased from the normal fibroblasts to those irradiated Fig. Histoenzymology and electron microscopy study.

September 17, ; Accepted: J Biol Buccale 15 1 The cellular heterocromstina pertaining to the irradiated fibroblasts showed an accentuated decrease, equivalent to 40 square microns in relation to the normal fibroblasts Table 1.
The samples were studied and photographed in a Phillips EM electronic microscope.
