In Vitro	Galactose is important for the survival and virulence of bacteria. In Escherichia coli galactose is utilized by the Leloir pathway. Two anomers of d-galactose are used for different purposes, α-d-galactose as a carbon source and β-d-galactose for induction of UDP-galactose synthesis for biosynthetic glycosylation[1].
In Vivo	Chronic D-galactose exposure induces neurodegeneration by enhancing caspase-mediated apoptosis and inhibiting neurogenesis and neuron migration in mice, as well as increasing oxidative damage. In addition, D-galactose-induced toxicity in mice is a useful model for studying the mechanisms of neurodegeneration and neuroprotective drugs and agents[2]. D-galactose given by oral route causes cognitive impairments in rats which are accompanied by oxidative damage. Cognitive impairments is observed in the open-field test in the 4th and 6th weeks after d-gal administration, as well as an impairment in spatial memory in the radial maze test after the 6th week of d-gal administration[3].
Animal Admin	Rats: D-galactose is dissolved in water for administration at the dose of 100 mg/kg of body weight, and given by oral gavage, once a day, over a period of 1, 2, 4, 6 or 8 weeks. Animals are randomized into two groups: control animals (receiving water by oral gavage) or d-gal animals (receiving D-galactose by oral gavage). The behavioral tests and biochemical analysis are undertaken on the1st, 2nd, 4th, 6th and 8th weeks after the last administration of d-gal[3]. Mice: Male adult C57BL/6 mice are randomly divided into three groups (control, D-galactose, and D-galactose plus α-LA). D-galactose (100 mg/kg) is injected subcutaneously (s.c.) daily into mice for 7 weeks. α-LA (100 mg/kg body weight) is injected peritoneally (i.p.) daily concomitantly for 7 weeks. All control animals are given saline[2].
