Prostaglandin levels and lysosomal enzyme activities in irradiated rats.
Whole-body irradiation of rats results in the release of hydrolases from lysosomes, an increase in lysosomal enzyme activities, and changes in the prostaglandin levels in spleen and liver tissues. A transient increase in the concentration of prostaglandins E and F and leakage of lysosomal hydrolases occurred in both spleen and liver tissues 3-6 hours after the animals were irradiated. Maximal v...
متن کاملRadiation-induced cell death: importance of lysosomal destabilization.
The mechanisms involved in radiation-induced cellular injury and death remain incompletely understood. In addition to the direct formation of highly reactive hydroxyl radicals (HO*) by radiolysis of water, oxidative stress events in the cytoplasm due to formation of H2O2 may also be important. Since the major pool of low-mass redox-active intracellular iron seems to reside within lysosomes, ari...
متن کاملDisruption of cyclooxygenase-1 gene results in an impaired response to radiation injury.
Prostaglandins may play an important role in regulating normal renewal of gastrointestinal epithelium, epithelial injury repair, and initiation or progression of intestinal neoplasia. Synthesis of prostaglandins is catalyzed by either of two cyclooxygenase isoforms, Cox-1 and Cox-2. Cox-1 is the predominant cyclooxygenase isoform found in the normal intestine. In contrast, Cox-2 is present at l...
متن کامل(Iso) Prostaglandins in saliva indicate oxidation injury after radioiodine therapy.
UNLABELLED As salivary glands concentrate radioiodine the radiation injury associated with 131I-therapy may result in sialoadenitis and xerostoma leading to a lasting impaired quality of life. Recently we reported about prostaglandin concentration changes as biochemical markers for radiation injury. Isoprostanes, a new family of prostaglandin-like compounds, have been demonstrated to be reliabl...
متن کاملAmeliorative effects of Hesperidin on radiation induced brain injury in rats
Background: Extensive research has been focused on radiation induced brain injury. Animal and human studies have shown that flavonoids have remarkable toxicological profiles. This study aims to investigate the neuroprotective effects of hesperidin in an experimental radiation induced brain injury. Materials and Methods: 32 adult male Wistar-Albino rats were randomly divided into 4 groups (contr...
