Astaxanthin, the Natural Antioxidant, Reduces Reserpine Induced Depression in Mice

Current Bioactive Compounds, 2020
Background: An imbalance between pro-oxidants and antioxidants determines the level of oxidative stress which is implicated in the etiopathogenesis of various neuropsychiatric disorders including depression. Therefore, treatment with antioxidants could potentially improve the balance between pro-oxidants and antioxidants. Objective: The objective of

Chemoprevention of mouse urinary bladder carcinogenesis by the naturally occurring carotenoid astaxanthin

Carcinogenesis, 1994
The chemopreventive effects of two xanthophylls, astaxanthin (AX) and canthaxanthin (CX), on urinary bladder carcinogenesis induced by N-butyl-N(4-hydroxybutyl)nitrosamine (OH-BBN) was investigated in male ICR mice. Mice were given 250 p.p.m. OH-BBN in drinking water for 20 weeks and after a 1 week interval with tap water, water containing AX or CX at ...
