Enriched Environment Induces Sex-Specific Changes in the Adult Neurogenesis, Cytokine and miRNA Expression in Rat Hippocampus.

An enriched environment stimulates adult hippocampal plasticity, but the exact cellular and molecular mechanisms are complex, and thus a matter of debate. We studied the behavior and hippocampal neurogenesis in adult male and female Wistar rats that were housed in an enriched environment (EE) for two months. Both EE males and females performed better than control animals in a Barnes maze, meaning that EE enhances spatial memory.

Single Prolonged Stress Decreases the Level of Adult Hippocampal Neurogenesis in C57BL/6, but Not in House Mice.

Many people experience traumatic events during their lives, but not all of them develop severe mental pathologies, characterized by high levels of anxiety that persists for more than a month after psychological trauma, such as posttraumatic stress disorder (PTSD). We used a single prolonged stress protocol in order to model PTSD in long-inbred C57BL/6 and wild-derived (house) female mice. The susceptibility of mice to single prolonged stress was assessed by behavior phenotyping in the Open Field and Elevated Plus Maze, the level of neuroinflammation in the hippocampus was estimated by real-time PCR to TNFα, IL-1β, IL-6, IL-10, Iba1 and GFAP, as well as immunohistochemical analysis of microglial morphology and mean fluorescence intensity for GFAP+ cells.

[Influence of microwave magnetoresonance therapy on various parameters of local immune defence in the respiratory tract in ailing children].

Microwave magnetoresonance therapy (MMT) was performed in 50 preschool children who had frequent respiratory infections. The assessment of local antiinfectious defense factors registered a significant decrease in the total number of circulating immune complexes (CIC) with disappearance of small CIC; enhancement of total complementory activity and C2, C4-fragments of the complement indicating activation of mucosa of the mucosa-associated lymphoid tissue inductive zone providing specific antibacterial defense of the upper respiratory tract.
