We conducted an immunoelectron-microscopic study for histamine (HA) in the enterochromaffin-like (ECL) cells of normal rats and rats given α-fluoromethylhistidine (α-FMH, 3 mg/kg per hour) via osmotic minipumps over a period of 24 h. The indirect immunoperoxidase procedure utilized a mouse monoclonal antibody (mAb), AHA-2, which is produced against(More)
We examined the intracellular mechanisms of substance P induced oxyradical production in rheumatoid synovial cells by the luminol-dependent chemiluminescence method. After stimulation with substance P (30 μM), single synovial A (macrophage-like) or B (fibroblast-like) cells released oxyradicals such as superoxide anions (OZ) and/or hypochlorous anions(More)
Pieces of fetal midbrain raphe tissue were transplanted into the third ventricle or the ventral hypothalamic region near the suprachiasmatic nucleus (SCN) of adult host rats that had previously been denervated by treatment with 5,6-dihydroxytryptamine. The ability of grafted serotonin neurons to reinnervate the SCN in the host rats was studied by means of(More)
Pieces of fetal midbrain raphe containing serotonergic and dopaminergic neurons were transplanted into the leptomeningeal tissue (see Fig. 3) of adult host rats that had previously been denervated by treatment with 5,6-dihydroxytryptamine. One, 2 and 5 months after transplantation, the rate of neuronal survival in the grafted tissue and the extent of axonal(More)
