Retrograde labeling was combined with cytochemistry to investigate phenotypic differences in primary afferent neurons relaying sensory information from deep and superficial craniofacial tissues. Calcitonin gene-related peptide (CGRP), substance P (SP), somatostatin (SOM) immunoreactivity and isolectin IB4, and cholera toxin B (ChTB) binding were examined(More)
A multivalent vaccine consisting of whole cell antigens of seven strains, representing four serotypes (b, c, d and g), of mutans streptococci was used to hyperimmunize a group of cows. Serum samples from these animals contained immunoglobulin G1 (IgG1) antibody activity to seven serotypes (a to g) of mutans streptococci. Whey obtained from the animal with(More)
Gnotobiotic rats gastrically intubated with a total of 12.5 micrograms of Streptococcus sobrinus ribosomal protein incorporated into cholesterol-based liposomes had significantly (P less than or equal to 0.01) fewer carious lesions on their molar surfaces than did nonimmunized infected controls after challenge with a virulent organism. The immunized animals(More)
Contractions of the transmurally stimulated guinea-pig ileum were not affected by 10 microM bicuculline, a competitive GABAA receptor antagonist. The GABAA potentiator alphaxalone depressed the responses to 2 and 20 Hz stimulation by 20% and 40%, respectively, but had no effect on 0.2 Hz responses. The depressions were prevented by 10 microM bicuculline.(More)
