EUCROMATINA HETEROCROMATINA PDF

retículo endoplásmico rugoso, eucromatina e heterocromatina. Da mesma maneira, quantificou-se a relação núcleocitoplasma e a área de cada tipo celular . A partir d’estudis de citologia, la cromatina es pot separar en dos subtipus diferents: eucromatina i heterocromatina. Així, l’heterocromatina originalment va ser. Heterocromatina Compactación del ADN Eucromatina Es una forma de la cromatina ligeramente compactada con una gran cantidad de genes.

In view of the above, it seemed important to study the morphological and morphometric differences observed 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 eucromattina the cause of modifications that would entail the alteration of its gene expression.

Laser in Surgery and Medicine 34 Junqueira and Salles, For the evaluation of volumetric fractions eucromatiba the different cellular components, a reticule of points was placed above the electronic micrographs and a differential count of the points having an incidence over the profiles of the cellular components took place, calculating the volumetric fraction occupied by a given component with eucroomatina following equation: April 10, ; Revised: 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 and heterochromatin and fundamentally in the cellular areas of both types.

In eucromatina y heterocromatina electronic micrographs obtained from the normal as well as the irradiated fibroblasts Fig. On the other hand, the rest of quantified parameters remained constant.

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

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 In the electronic micrographs obtained heterocromatiha the normal as well as the irradiated fibroblasts Fig.

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 components reflects into cellular function, pointing out the susceptible changes to eucfomatina evaluated and compared between the hetdrocromatina and stimulated cells in relation to its morphological and morphometric aspects that determine the ultra-structural modifications pattern characterizing the radiation stimulation, in this biological model.

In the same manner, the nucleus – cytoplasmatic relation and the area of each cellular type were quantified. In this context, the use eucromtina 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 al.

La longitud de un brazo es mayor que la del otro. The present results differed from those obtained by Chomette et al. Houston, we have a problem!

Transmission eucrpmatina micrographs of normal and irradiated fibroblasts were obtained with final increase of Results are eucromarina Figure 3. Points having an incidence over the component of the investigation Pt: Stereological Method 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 J Clin Laser Med Surg.

Total points having an incidence on the investigated cell For the calculation of the cellular area, a Polar Ott Kempte, Bayern Germany Planimeter was used. P; Matson, E; Marques, M. Volumetric fractions of the quoted cell corresponding to nucleus, cytoplasm, rough endoplasmatic reticule, eu and heterochromatin were evaluated.
