Volumetric fractions eucromatina y heterocromatina the quoted cell corresponding to nucleus, cytoplasm, rough endoplasmatic reticule, eu and heterochromatin were evaluated.

In the same manner, the nucleus – cytoplasmatic relation and the area of each cellular type were quantified. 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 results eucromatina y heterocromatina the analysis of eucromatina y heterocromatina morphological data obtained with the transmission electronic microscopy fundamentally considering those relative to the similar volumetric fractions of cytoplasm, nucleus and those corresponding to the rough endoplasm reticule from the normal as well as irradiated fibroblasts, demonstrated that these cells possessed similar eucromatina y heterocromatina parameters, indicating that the effects produced by the stimulations with infrared laser did not have an inhibiting action, nor an activating one of the cellular activity, situation which would translate in concluding primarily that these cells displayed a cellular function eucromatina y heterocromatina to a rate of protein synthesis-secretion practically similar.

The results derived from heteroctomatina morphometric comparative study between the normal and irradiated fibroblasts indicated that there were significant differences with respect to the volumetric eucromatina y heterocromatina of euchromatin and heterochromatin and fundamentally in the cellular areas of both types.

Neither you, nor the coeditors you shared it with will be able to recover it again. It would be pertinent to recall that this effect, a product of the eucromatina y heterocromatina, decreased the area of the irradiated cell to one half, 82 to 40 square microns eucromatina y heterocromatina it in the typical morphology of a “juvenile” fibroblast, making it tempting to suppose that this situation was the translation of a change in the gene expression modulated by these infrared stimulations.

Transmission electronic micrographs of eucromatina y heterocromatina and irradiated fibroblasts were obtained with final increase of 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.
