Abstract: Anaemia is an important factor in the response of some human tumours to radiotherapy. The outcome is also influenced by whether the treatment is given in air or high pressure oxygen (HPO). The present study examined the relationship between anaemia and...
Abstract: This paper is a retrospective analysis of 397 patients with glottic cancer, in which 240 patients were treated in air, and 157 patients in a hyperbaric oxygen chamber (HBO). The three principal dose/time schedules in air and HBO are contrasted, and shown to...
Abstract: The effects of hyperbaric oxygen on uracil nucleotide metabolism in B104 rat neuroblastoma cells were investigated. Cells exposed to 10 atm O2 for 4 h incorporated markedly less [3H]uridine into the acid-soluble fraction and RNA compared to cells kept in...
Abstract: Twenty-one patients with nonresectable non-small-cell lung cancer (15 squamous-cell, 4 adeno, 2 large-cell; T1-T3, N0-N2, all M0) underwent lymph node dissection and intraoperative irradiation of the tumor (IORT) with doses between 10 and 20 Gy (energies: 7...
Abstract: The cytologic effects of radiation therapy involve all tissues and most significantly bone within the treated area. Of greatest concern is the permanence of the compromised healing and resistance to infection of the irradiated tissues. Those dental...
Abstract: The effect of hyperbaric oxygen (HBO) on the growth of anaplastic carcinoma colonies in rat lungs after intravenous tumor cell injection was studied. From the first day after tumor cell injection, the rats were exposed to HBO for 16-21 days, 90 min per day....
Abstract: The effect of higher oxygen pressures (0.3 MPa, 5 sessions 1 h each daily) on induction of chromosomal aberrations in somatic cells and germinal tissues of rat males has been studied. Appearance of aberrations in bone marrow cells after HBO was recorded for...
Abstract: Data are presented to indicate the value of hyperbaric oxygen in all stages of treatment of patients with irradiation complications following head and neck surgery. Hyperbaric oxygen stimulates angiogenesis, with increased neovascularization and optimization...
Abstract: Osteoradionecrosis (ORN) is one of the most serious complications arising from head and neck radiation therapy. Current research has shown that ORN represents nonhealing, dead bone and is not a state of infection. ORN is the result of functional and...
Abstract: Retrospective study of one years is performed on 334 patients who undergo transurethral surgery. Spinal anesthesia is used in 263 cases, general anesthesia in 71. Spinal administration of local anesthetics (lidocaine hyperbaric 5% or bupivacaine 0.5%) or...
