Adaptive changes of redox status in rat brain tissues due to decimeter microwave irradiation
Electromagnetic waves affect living organisms and it is of great interest for wide interaction of new sources with a diversity of frequencies and powers to life of people. In the last few years, many authors have proposed that the biological effect of electromagnetic fields in both the high-frequency and low-frequency ranges are connected with oxidative processes in tissues. Studying the change...

متن کاملEndosseous Implants in Irradiated Tissues
This paper discusses the use of endosseous implants in irradiated bone. The success rate of endosseous implants in irradiated bone is reviewed and controversy over optimal time prior to implant placement is described. The advantages and disadvantages of preand postimplant radiotherapy are addressed. Implant therapy and osteoradionecrosis (ORN) and evidence of potential role of hyperbaric oxygen...
متن کاملRadiation Damage to Thoracic Tissues.
Radiotherapy to the thorax in conventional dosage appears to be capable of causing damage to any of the tissues in the thoracic wall or within the thoracic cavity. Since the earliest days of x-ray treatment radiation changes in the skin have been such an everyday problem that they scarcely warrant discussion here except to note that with the advent of new radiotherapeutic techniques they are be...
متن کاملLong-term histological comparison between near-infrared irradiated skin and scar tissues
BACKGROUND AND OBJECTIVE Our previous histological studies indicated that near-infrared (NIR) irradiation stimulates collagen proliferation in rat and human skin for 3 months. High collagen density in the dermis and smoothing of the epidermis were observed in irradiated rat skin, and appeared to last up to 6 months. Epidermal smoothness in irradiated rat skin seems to resemble scarring. Here, w...
