“…Rh frequencies, which represent all haplotypes of d, were estimated on the assumption of HardyWeinberg equilibrium proportions. The gene frequency data were adapted to calculate genetic distances between the towns using a derivation by Roberts, Mitchell, Creen and Jorde (1981) of the R matrix method of Harpending and Jenkins (1973). The comparison between genetic and geographical distances was performed using the MATFIT program (Lalouel 1973), which rotates the two distance matrices to maximum congruence.…”

Data are presented on the ABO and Rh(D) frequencies of 1685 individuals living in the Ards Peninsula, northeastern Ireland. Previous investigations based on surname analysis and linguistic studies showed a basic north-south population divide that could be traced back at least to the early seventeenth century. The current survey indicates the continuation of this divide, which is coincident with known patterns of religious persuasion.

“…Immunological and biochemical analysis of whole mixed saliva is useful in the diagnosis of various systemic diseases such as Gougerot-Sjogren syndrome (Pennec et al 1982), colon carcinoma (Northoff et al 1983), and fucosidosis (Den Tandt & Jaeken 1979), as well as in studies of human genetics (Teng & Tan 1979, Herron et al 1980, Roberts et al 1981. One important component in these anaiyses are salivary enzymes.…”

This study determined changes in the levels of enzymes in whole mixed saliva of adults following periodontal therapy including two or more sessions of meticulous periodontal scaling and root planing and 1 g/day of tetracycline‐HCI for 14 days. Clinical variables assessed at baseline and 2 weeks after treatment included Gingival Index, Plaque Index, periodontal pocket depth, and gingival crevicular fluid flow. Subgingival specimens obtained from the deepest periodontal pocket in each quadrant were analyzed for Bacteroides gingivalis and Bacteroides intermedius using indirect immunofluorescence microscopy and for bacterial morphotypes using bright light phase contrast microscopy. The enzymatic profile of unstimulated whole mixed saliva was determined using the API ZYM and API ZYM AP micromethod systems. Periodontal treatment significantly reduced gingival inflammation and the proportions of subgingival black‐pigmented bacteroides and motile organisms. However, the Plaque Index and total salivary bacterial counts remained virtually unchanged. Treatment also resulted in reduced salivary levels of caprylate esteraselipase, leucine, valine, and cystine aminopeptidases, trypsin, β‐galactosidase, β‐glucuronidase, and β‐glucosidase. The present study indicates that the efficacy of periodontal treatment may be readily monitored by changes in levels of activity of specific enzymes in whole saliva.

“…Consideration of present day migration and genetic drift having been taken into account, the way was clear for interpretation in terms of more ancient population settlement. The gene frequencies of this region are in fact more similar to present day Norwegian genes than to the neighbouring regions (Roberts et al, 1981b). The point I wish to make is this: we should not infer migration on the basis of gene frequency similarities without some independent documentation of the populations' relationship, and we should not exclude other microevolutionary processes from consideration without first assessing their applicability in the situation under review.…”
