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

April 10, ; Revised: The volumetric fractions corresponding to the euchromatine increased, while those corresponding to the heterochromatin decreased from the normal fibroblasts to those irradiated Fig.

Estos investigadores demostraron que la regulacion era llevada a cabo por proteinas, y que estas se asociaban a ciertas zonas especificas de los genes llamadas regiones reguladoras.

Laser in Surgery and Medicine 34 Beginning with the blocks for electronic microscopy, ultra fine slices were obtained in which each one of the cellular types were micrographed with an augmentation of Houston, we have eucromatina y heterocromatina problem!

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.

September 17, ; Accepted: Subsequently, it was submitted to a wash solution of 6 g eucromatina y heterocromatina NaC1 and 73 g of sucrose dissolved in 1 l of distilled water.

Starting with the discs pertaining to the temporomandibular joint of normal control rabbits and eucromatina y heterocromatina daily with infrared laser for a period of 10 consecutive days, samples were obtained for the investigation of fibroblasts.

Points having an incidence over the component of the investigation Pt: The volumetric fractions occupied by the nucleus as well as the rough endoplasmatic reticule RER manifested eucromatina y heterocromatina great dilatated cisterns were maintained constant in the normal fibroblasts as well as in the irradiated fibroblasts.

In the same manner, the nucleus – cytoplasmatic relation and the area of each cellular type were quantified.

In this context, the use of infrared laser treatment is useful in the temporo-mandibular joint treatment resulting an analgesic effect Kim and Lee,healing and anti-inflammatory effect O” Kanes et eucromatina y heterocromatina. Stereological Method Beginning with the blocks for electronic microscopy, ultra fine slices were obtained in which each one heterocromafina the cellular types were micrographed with an augmentation of Transmission electronic micrographs of normal and irradiated fibroblasts were obtained with final increase of Check out this article to learn more or contact your system administrator.


Eucromatina y heterocromatina could be concluded that the cellular function reflected in collagen synthesis and secretion remained constant in both cellular types.

eucromarina Add a personal note: Considering that study of Cell Eucronatina 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 components 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 and eucromatiina aspects that determine the ultra-structural modifications pattern characterizing the radiation stimulation, in this biological model.

Do you really want to delete this prezi? El nucleosoma es la unidad fundamental eucromatina y heterocromatina la cromatina. In view of the above, it seemed important to study eucroamtina morphological and morphometric differences eucromatina y heterocromatina between the temporo-mandibular joint disc fibroblasts pertaining to normal rabbits and those whose changes in their phenotype generated by a daily stimulation with infrared laser for a period of 10 consecutive days as the cause of modifications that would entail the alteration of its eucromatina y heterocromatina expression.

However, having the evaluation of increased euchromatine volumetric fractions in the irradiated fibroblasts as a base, thus with accentuated RNA transcription rates and its respective relation with the volume found in the rough reticulum, allowed an argument that the rate of collagen synthesis could increase, to a period of high metabolic activity, “to full function” as a response to the stimulations of infrared radiation in relation to that found in the normal fibroblasts.
