Acute and chronic administration of ibogaine to the rat results in astrogliosis that is not confined to the cerebellar vermis.

Annals of the New York Academy of Sciences October 31, 1996 J P O'Callaghan, T S Rogers, L E Rodman et al. 14 citations

Acute administration of high doses of ibogaine (IBG) to the male rat results in degeneration of Purkinje cells and reactive gliosis in the cerebellar vermis. We examined whether acute and chronic administration of IBG to male and female rats results in gliosis as determined by quantification of the astroglial intermediate filament protein, glial fibrillary acidic protein (GFAP). After acute...

The role of temperature, stress, and other factors in the neurotoxicity of the substituted amphetamines 3,4-methylenedioxymethamphetamine and fenfluramine.

Molecular Neurobiology August 1, 1995 D B Miller, J P O'Callaghan

Amphetamines (AMPs) can cause long-term depletions in striatal dopamine (DA) and serotonin (5-HT), and these decrements are often accepted as prima facie evidence of AMP-induced damage to the dopaminergic and serotonergic projections to striatum. Rarely are indices linked to neural damage used to evaluate the neurotoxicity of the AMPs. Here, we determined the potential neurotoxic effects of two...

Neurotoxicity profiles of substituted amphetamines in the C57BL/6J mouse.

Journal of Pharmacology and Experimental Therapeutics August 1, 1994 J P O'Callaghan, D B Miller

Dopaminergic (DA) and serotonergic (5-HT) projections to striatum and cortex have been implicated as the primary targets of substituted amphetamine (AMP)-induced neurotoxicity, largely on the basis of the propensity of these compounds to cause protracted decrements in DA and 5-HT rather than on the basis of AMP-induced alterations of indices linked to neural damage. Moreover, most studies of...

Environment-, drug- and stress-induced alterations in body temperature affect the neurotoxicity of substituted amphetamines in the C57BL/6J mouse.

Journal of Pharmacology and Experimental Therapeutics August 1, 1994 D B Miller, J P O'Callaghan

In the companion paper we demonstrated that d-methamphetamine (d-METH), d-methylenedioxyamphetamine (d-MDA) and d-methylenedioxymethamephetamine (d-MDMA), but not d-fenfluramine (d-FEN), appear to damage dopaminergic projections to the striatum of the mouse. An elevation in core temperature also was associated with exposure to d-METH, d-MDA and d-MDMA, whereas exposure to d-FEN lowered core...
