According to a study published by "Folia medica", Landolphia owariensis was assessed for its effect on alcohol-induced neurodegeneration of the cerebellar cortex in rats. The study involved groups of rats fed 5 g/kg ethanol (25% w/v) and others receiving 5 g/kg ethanol (25% w/v) plus Landolphia owariensis at 100 mg/kg body weight in a diluted nutritionally complete diet (50% v/v). After 4 days of binge alcohol treatment, Landolphia owariensis supplementation significantly lowered the levels of histologic and biochemical indices of neurodegeneration. This plant reduced the level of neurodegeneration and cytoa rchitecture distortion of the cerebellar cortex in rats exposed to ethanol. Landolphia owariensis attenuates alcohol-induced cerebellar degeneration by alleviating oxidative stress and the alteration of neurofilament protein expression in the Purkinje cells.
