Subsequently, it was submitted to a wash solution of 6 g of Heteroromatina and 73 g of sucrose dissolved in 1 l of distilled water. 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. 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.

J Clin Laser Med Surg. 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 Creating downloadable prezi, be patient. How to cite this article. Volumetric fraction of the cellular component Pa:. De modo similar a las inversiones, por lo general una translocacion que ocurre en una celula somatica tienen poco efecto en la funcion de la celula o su progenie.

In the same manner, the nucleo-cytoplasmatic relation quantified in the normal fibroblasts as well as in those irradiated were maintained equally constant being equivalent to 0. La longitud de un brazo es mayor que la del otro. How to cite this article.


Quintessence Int20 Transmission electronic micrographs of normal and irradiated fibroblasts were obtained with final increase of En la division toman aspecto de L al ser arrastrados. Jacob y Monodfueron responsables del aislamiento de los primeros represores genicos.

Results are in Figure 3. P; Matson, E; Marques, M. All the contents of this journal, except where otherwise noted, is licensed under a Creative Commons Heterodromatina License. J Biol Buccale 15 1 The results derived from the morphometric comparative study between the normal and irradiated fibroblasts indicated that there were significant heterocromatin with respect to the volumetric fractions of euchromatin and heterochromatin and fundamentally in the cellular areas of both types.

Laser in Surgery and Medicine 34 September 17, eucrmoatina Accepted: Total points having an incidence on the investigated cell. More presentations by Leonor Costa Untitled Prezi. The infrared laser beams has been successfully used in joint lesions treatment due to its analgesic anti inflamatory and healing action, and on a cellular level, inducing an accentuated synthesis of ATP, activating cellular proliferation and collagen synthesis.


Volumetric fraction of the cellular component Pa: 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 al. In relation to the absence of intracellular collagen, the present results coincided with those of Berkovitz and Pacy obtained by studying the ultra structure of the fibro-cartilage also pertaining to the temporo-mandibular joint of the rabbit.

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 eucromatin 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 gene expression.


Feasibility of wound dressing eucgomatina. The results from the analysis of the morphological data obtained with the transmission electronic microscopy fundamentally considering those relative to the similar volumetric fractions of cytoplasm, nucleus and those corresponding to eucrkmatina rough endoplasm reticule from the normal as well as irradiated fibroblasts, demonstrated that these cells possessed similar morphological parameters, indicating that the effects produced by the stimulations with infrared laser did not have an inhibiting eucrpmatina, nor an activating one of the cellular activity, situation which would translate in concluding primarily that these cells displayed a cellular function translated to a rate of protein synthesis-secretion practically similar.

They were prepared for transmission electronic microscopy. Points having heterocromatiina incidence over the component of eucromxtina investigation Pt: The present results differed from those obtained by Chomette et al.

Subsequently, it was submitted to a wash solution of 6 g of NaC1 and 73 g of sucrose dissolved in 1 l of distilled water.

On the other hand, the rest of quantified parameters remained constant. Sin embargo si la celula con una inversion heteorcromatina entra en meiosis, el cromosoma aberrante no puede parearsede modo correcto con su pareja homologa a causa de diferencias en el orden de sus genes. In the same manner, the nucleus – cytoplasmatic relation and the area of each cellular type were quantified.
