Q: Abstract: The microbial flora of recurrently inflamed tonsils removed from 25 children with recurrent episodes of tonsillar pharyngitis were compared to flora of tonsils removed from 23 adults suffering from similar illness. More bacterial isolates per tonsil were recovered in adults (10.2 per tonsil) than in children (8.4 per tonsil). The difference between these groups was due to a higher recovery rate in adults of Bacteroides melaninogenicus group (1.6 isolates per adult, 0.8 per child) and Bacteroides fragilis group (0.4 per adult, 0.2 per child). Conversely, Group A beta-hemolytic streptococci were isolated in seven (28%) children as compared to their isolation in one (4%) adult. More isolates of beta-lactamase-producing organisms (BLPO) per tonsil were recovered in adults. Forty-three BLPO were detected in 21 (91%) of the 23 tonsils removed from adults (1.9 isolates per patient) as compared to 31 isolates in 16 (64%) of the 25 tonsils removed from children (1.2 isolates per patient) (P = 0.04). These findings suggest that the etiology of recurrent tonsillitis in adults may differ from that in children. The differences in the tonsillar flora may be due to the effect of many more courses of antimicrobials given over the years to adults and the changes in tonsillar tissue that occur in this age group.

Q: Abstract: The effect of prolonged osmotic stimulation on the oxytocin (OT) mRNA levels of OT-producing neurons was investigated in separate hypothalamic nuclei of the rat. After drinking 2% NaCl for 2 weeks, a 2-fold increase in the OT mRNA content was found by Northern blot analysis of microdissected supraoptic nucleus (SON) and paraventricular nucleus (PVN). The same samples showed a similar change in vasopressin (VP) mRNA levels. This treatment resulted in a 70% depletion of both OT and VP from the neurointermediate lobe of the pituitary gland and a marked increase in OT and VP plasma levels. Analysis of the OT mRNA concentration by quantitative in situ hybridization showed that the SON, PVN, and anterior commissural nucleus responded similarly, with a 1.5-fold increase in OT mRNA after 7 days of osmotic stimulation. These results demonstrate that OT gene expression in the magnocellular neurons of the SON, PVN, and anterior commissural nucleus is sensitive to this osmotic stimulus, as is the VP gene of magnocellular neurons in the SON and PVN. The responsiveness of OT-producing neurons may point to a role for OT in the regulation of water and electrolyte balance.

Q: Abstract: Cell-mediated and humoral immune responses were assessed in 50 patients with oral submucous fibrosis (OSMF) and the results were compared with those of 50 patients with oral-leukoplakia, 50 oral cancer patients, and 50 normal healthy adult controls. The number of high-affinity rosette-forming cells (HARFC) was found to be significantly decreased in OSMF and oral cancer, whereas the number of total rosette-forming cells (TRFC) remained unaltered. Levels of serum IgA, IgD, and IgE were found to be elevated both in OSMF and oral cancer. Immunologic derangements were found to be more pronounced in oral cancer than in OSMF. The enumeration of HARFC along with the estimation of serum levels of IgA, IgD, and IgE indicates that OSMF can be an intermediary stage in the malignant transformation of a normal cell, and that these parameters may serve as markers for the early detection of oral cancer.
