Quantitative Study of Neurons with Intracytoplasmic Pigments in Dorsal Root Ganglia Atomic Bomb and Aging
نویسندگان
چکیده
Three females in their fifties and five males in their seventies, all of whom had been exposed to the Nagasaki atomic bomb explosion in 1945, were investigated concerning the aging of neurons of the dorsal root ganglia. Through this study dealing with the frequency of neurons with intracytoplasmic pigments, lipofuscin, neuromelanin, eosinophilic granules and neurons free of pigment, no significant difference in four kinds of neurons between the exposed persons and the nonexposed persons was detected in 50-59 year-old females. Contrariwise in the 70-79 year-old males, the frequency, as average but not as individual persons, was significantly higher in lipofuscin, lower in neuromelanin, and unchanged in eosinophilic granules and no pigment.

Role of a voltage-sensitive calcium channel blocker on inhibition of apoptosis in sensory neurons of cultured dorsal root ganglia in adult rat
Introduction: Under pathological conditions, abnormal increase in intracellular calcium concentrations is believed to induce cell death. In the present study, a voltage-sensitive calcium channel blocker (loperamide hydrochloride) was used to investigate its role in inhibition of apoptosis in sensory neurons of cultured spinal dorsal root ganglia (DRG). Methods: L5 DRG from adult rats were di...

Background and Objective: The neuroprotective effect of uric acid as a natural antioxidant on neurodegenerative diseases has been proposed repeatedly, but its antiapoptotic effect on spinal neurons has not been examined yet. Due to the critical role of sensory neurons in the improvement of functional outcome in neuroprotective strategies, the antiapoptotic effect of uric acid on dorsal root gan...
متن کاملAdrenomedullin protects rat dorsal root ganglion neurons against doxorubicin-induced toxicity by ameliorating oxidative stress
Objective(s): Despite effective anticancer effects, the use of doxorubicin (DOX) is hindered due to its cardio and neurotoxicity. The neuroprotective effect of adrenomedullin (AM) was shown in several studies. The present study aimed to evaluate the possible protective effects of AM against DOX-induced toxicity in dorsal root ganglia (DRGs) neurons. M...

Neurite outgrowth from dorsal root ganglion (DRG) explants is a method of evaluating neurotrophic activity of growth factors. When complete medium containing collagen was supplemented with nerve growth factor (NGF) DRG outgrowth was observed after 18 h. In the absence of NGF and in the presence of collagen, the DRG outgrowth took place after 72 h. In wells not supplemented with collagen gel in ...

Background and Objective: Sensory neurons have critical role in improvement of functional outcome of any neuroprotective strategy. The herbal medicine Nepeta menthoides has been reported to have anti-apoptotic effect on axotomized spinal motoneurons. In the present study, the putative neuroprotective effect of Nepeta menthoides on the axotomized dorsal root ganglion sensory neurons in neonate r...
