The objective of the present study was to determine whether there was an association between the in vitroantimicrobial sensitivity test results of subclinical mastitis pathogensand bacteriological cure following intramammary treatment using a combination of nafcillin, penicillin, and streptomycin (NPS). Eighty-six intramammary pathogens from 43 cows were examined inthis study. Most intramammary...

We report a case of accidental subcutaneous infusion of remifentanil as a cause of delayed awakening after a craniotomy.

Rats were infused with norepinephrine or saline intraventricularly in a free-field situation and while performing a continuous avoidance task (Sidman avoidance). The results indicate that central administration of norepinephrine may lead to behavioral activation in the rat.

Septal infusions of the gamma-aminobutyric acid (GABA)(A) agonist muscimol impair memory, and the effect likely involves the hippocampus. GABA(A) receptors are present on the perikarya of cholinergic and GABAergic septo-hippocampal (SH) projections. The current experiments determined whether GABAergic SH projections are involved in the memory-impairing effects of septal GABA(A) receptor activat...

Medial perforant path plasticity can be attenuated by 2-amino-5-phosphonovaleric acid (APV) infusions, whereas lateral perforant path plasticity can be attenuated by naloxone infusions. The present experiment was designed to evaluate the role of each entorhinal efferent pathway into the dorsal hippocampus for detection of spatial and nonspatial (visual object) changes in the overall configurati...
