In Vivo | The Thimerosal (THIM) administration increases μ-opioid receptors (MORs) density in the periaqueductal gray (PAG) in a dose-dependent manner. Treatment with higher doses of Thimerosal statistically significantly increases MOR density in the dorsomedial periaqueductal gray (DMPAG) and lateral periaqueductal gray (LPAG) regions. At the dose 3,000 μg Hg/kg, Thimerosal also augments MOR density in the caudate putamen (CPU). In contrast, the administration of Thimerosal at both higher doses decreases MOR density in the dentate gyrus (DG)[1]. Thimerosal administration (4 injections, i.m., 240 μg Hg/kg on postnatal days 7, 9, 11, 15) induces lasting changes in amino acid overflow: an increase of glutamate and aspartate accompanied by a decrease of glycine and alanine; measured 10 to 14 weeks after the injections. Four injections of Thimerosal at a dose of 12.5 μg Hg/kg do not alter glutamate and aspartate concentrations at microdialysis time. Application of Thimerosal to the prefrontal cortex (PFC) in perfusion fluid evokes a rapid increase of glutamate overflow. Coadministration of the neurosteroid, dehydroepiandrosterone sulfate (DHEAS; 80 mg/kg; i.p.) prevents the Thimerosal effect on glutamate and aspartate; the steroid alone has no influence on these amino acids. Coapplication of dehydroepiandrosterone sulfate (DHEAS) with Thimerosal in perfusion fluid also blocks the acute action of Thimerosal on glutamate[2]. |
Animal Admin | Male rats are used in this study. On the 20th postnatal week, the animals are euthanized by pentobarbital overdosing, and then decapitated. The rats treated with two higher doses of Thimerosal (THIM) (1,440 and 3,000 μg Hg/kg) are from the original litters, which are used for different behavioral and pathological tests, but are experimentally naïve. A separate group of experimentally naïve rats, treated with two lower doses of Thimerosal, 12 and 240 μg Hg/kg (4 litters per each drug-treatment) is sacrificed on the 8th postnatal week according to the same procedure. Each experimental group is composed of 5 animals, with 2 at the most coming from the same litter[1]. |
