The cellular area pertaining to the irradiated eucromatina y heterocromatina showed an accentuated decrease, equivalent to 40 square microns in relation to the normal fibroblasts Table 1. On the other hand, the rest of quantified parameters remained constant. Results are in Figure 3.

Eucromatina – Viquipèdia, l’enciclopèdia lliure

J Biol Buccale 15 1 Starting with eucromatina y heterocromatina discs pertaining to the temporomandibular joint of normal control eucromatiba and irradiated daily with infrared laser for a period of 10 consecutive days, samples were obtained for the investigation of fibroblasts.


Tradicionalmente la cromatina se divide en dos tipos: 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. For the evaluation of volumetric fractions of 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 the following equation: 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.

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.
