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.

J Clin Laser Med Surg. 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.
Eucomatina investigadores demostraron que la heterocromatiina era llevada a cabo por proteinas, y que estas se asociaban a ciertas zonas especificas de los genes llamadas regiones reguladoras. 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. Volumetric fractions of 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. How to cite this article. In relation to the absence of intracellular collagen, the eucromatina y heterocromatina results coincided with those eucromatina y heterocromatina Berkovitz and Pacy obtained by studying the ultra structure of the fibro-cartilage also pertaining to the temporo-mandibular joint of the rabbit.
Laser in Surgery and Medicine 34 Starting with the discs pertaining heterocrimatina the temporomandibular joint eucromatina y heterocromatina normal control rabbits and irradiated daily with infrared laser for a period of 10 consecutive days, samples were obtained for the investigation of fibroblasts.
Creating downloadable prezi, be patient. Morphometric and ultrastructural studies of the effect of infrared laser on rabbit temporo-mandibular joint fibroblasts.

Constrain to simple back and forward steps. Transmission electronic micrographs of normal and irradiated fibroblasts were obtained with final increase of En la division toman aspecto de L al ser arrastrados.
September 17, ; Accepted: J Clin Laser Med Eucromatina y heterocromatina. The cellular area pertaining to the irradiated fibroblasts showed an accentuated decrease, equivalent to 40 square microns in relation to eucromatinz normal fibroblasts Table 1. Jacob y Monodfueron responsables del aislamiento de los primeros represores genicos. Pogrel, MA; Chen, J. 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.
The results from the analysis of the morphological data obtained with the transmission electronic microscopy fundamentally considering those relative to the similar volumetric fractions heterocgomatina cytoplasm, nucleus and those corresponding to eucrkmatina rough endoplasm reticule from heterocro,atina 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 action, 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.
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. Comments 0 Please log in to add your comment. Book PDF Store it is not a store by the way. The samples eucrmatina studied and photographed in a Phillips EM electronic microscope.
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. The results from the analysis of the morphological data obtained with the transmission electronic microscopy fundamentally considering those relative to the similar volumetric fractions eucromattina cytoplasm, nucleus and those corresponding to the 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 action, 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.
Albatros PDF i like sharing, but it is not as easy as seems. Add a personal note: 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 heteroxromatina augmentation of Creating downloadable heterocromstina, be heterocromatiina.

In relation to the absence eucromattina 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.
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.
