Cellular Types

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. Samples of normal-control and irradiated tissue from temporo-mandibular joint disc of rabbit, were obtained, with daily doses of 2 joules/cm²during 10 consecutive days. They were prepared for transmission electronic microscopy.Transmission electronic micrographs of normal and irradiated fibroblasts were obtained with final increase of 11.500 X for morphometric studies with the purpose of quantifying the volumetric fractions of the cellular components pertaining to the mentioned cellular types. 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. 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. On the other hand, the rest of quantified parameters remained constant. It could be concluded that the cellular function reflected in collagen synthesis and secretion remained constant in both cellular types. However, by means of infrared laser stimulations, this fibroblast facilitated protein synthesis, due to high percentage of transcriptionally active euchromatine.
