Ganoderma tsugae prevents cognitive impairment and attenuates oxidative damage in d-galactose-induced aging in the rat brain.

Lingzhi has long been regarded as having life-prolonging effects. Research in recent years has also reported that Lingzhi possesses anti-tumor, anti-inflammatory, immunomodulatory, hepatoprotective, and anti-lipogenic effects. The D-galactose (D-gal, 100 mg/kg/day)-induced aging Long-Evans rats were simultaneously orally administered a DMSO extract of Ganoderma tsugae (GTDE, 200 μg/kg/day) for 25 weeks to investigate the effects of GTDE on oxidative stress and memory deficits in the D-galactose-induced aging rats.

In Vitro and In Vivo Analysis of the Effects of 3,5-DMA and Its Metabolites in Neural Oxidative Stress and Neurodevelopmental Toxicity.

3,5-Dimethylaniline (3,5-DMA), a monocyclic aromatic amine, is widely present in a spectrum of sources including tobacco, dyes, combustion products, and suspended particulates. 3,5-DMA and its metabolites form superoxides, resulting in apoptosis or oncogenesis. Data of a direct effect of 3,5-DMA on the nervous system, especially the developing brain, are lacking.
