LPS administration iv does not influence dopaminergic neuronal viability. (A) Midbrain sections of animals receiving LPS or PBS iv were obtained at 8 d, and stained with an anti-TH antibody. Scale bars: 200 µm (left panels) and 50 µm (right panels). (B) By stereology, the total numbers of TH+ neurons were estimated in the SNpc of LPS- or PBS-injected rats, as described in Methods. Values are means ± SEMs of data from three animals.
