Abstract
An additional microscopic diagnostic sign has been identified for verification of asphyxial type of drowning. In white non-linear male rats (age 2 months) subjected to free drowning, significant hyperplasia of argyrophilic and morphofunctional activity of serotonin-containing APUD-cells of the laryngeal mucosa were revealed under conditions of acute anoxia in comparison with the intact control. These changes promote the development of laryngospasm, which prevents water penetration into the airways and lungs in asphyxial type of drowning. The presence of statistically significant hyperplasia of argyrophilic and morphofunctional activity of serotonin-containing APUD-cells of the laryngeal mucosa under conditions of acute anoxia can be used as an additional diagnostic criterion for asphyxial type of drowning in experimental studies.
为验证窒息型溺水,还发现了另一个显微诊断标志。在接受自由溺水的白色非线性雄性大鼠(2 个月大)中,与完好的对照组相比,在急性缺氧条件下喉部粘膜含羟色胺的 APUD 细胞的嗜碱性和形态功能活性显著增生。这些变化促进了喉痉挛的发展,从而在窒息型溺水中阻止水渗入呼吸道和肺部。在急性缺氧条件下,喉粘膜含羟色胺的 APUD 细胞出现统计学意义上的增生和形态功能活性,可作为实验研究中窒息型溺水的额外诊断标准。
期刊介绍:
Bulletin of Experimental Biology and Medicine presents original peer reviewed research papers and brief reports on priority new research results in physiology, biochemistry, biophysics, pharmacology, immunology, microbiology, genetics, oncology, etc. Novel trends in science are covered in new sections of the journal - Biogerontology and Human Ecology - that first appeared in 2005.
World scientific interest in stem cells prompted inclusion into Bulletin of Experimental Biology and Medicine a quarterly scientific journal Cell Technologies in Biology and Medicine (a new Russian Academy of Medical Sciences publication since 2005). It publishes only original papers from the leading research institutions on molecular biology of stem and progenitor cells, stem cell as the basis of gene therapy, molecular language of cell-to-cell communication, cytokines, chemokines, growth and other factors, pilot projects on clinical use of stem and progenitor cells.
The Russian Volume Year is published in English from April.
