    Notes: Abstract Broadening of the genetic base and systematic exploitation of heterosis in cultivated lentils requires reliable information on genetic diversity in the germplasm. The ability of random amplified polymorphic DNA (RAPD) to distinguish among different taxa of Lens was evaluated for several geographically dispersed accessions/cultivars of four diploid Lens species. This study was carried out to assess whether RAPD data can provide additional evidence about the origin of the cultivated lentil and to measure genetic variability in lentil germplasm. Three cultivars of Lens culinaris ssp. culinaris, including one microsperma, and two macrosperma types, and four wild species (L. culinaris ssp. orientalis, L. odemensis and L. nigricans) were evaluated for genetic variability using a set of 1 11-mer and 14 random 10-mer primers. One hundred and fifty-eight reproducible and scorable DNA bands were observed from these primers. Genetic distances between each of the accessions were calculated from simple matching coefficients. Split decomposition analysis of the RAPD data allowed construction of an unrooted tree. This study revealed that (1) the level of intraspecific genetic variation in cultivated lentils is narrower than that in some wild species. (2) L. culinaris ssp. orientalis is the most likely candidate as a progenitor of the cultivated species, (3) L. nigricans accession W6 3222 (unknown) and L. c. ssp. orientalis W6 3244 (Turkey) can be reclassified as species of L. odemensis and (4) transmission of genetic material in Lens interspecific hybrids is genotypically specific, as identified by the RAPD markers in our study.

    The AHA syndrome: arthritis, hives and angioedema (1987)

    Notes: Summary Nine patients who have intermittently exhibited the concurrent triad of arthritis or arthralgia (A), hives or urticaria (H) and angioedema (A), in the absence of associated infection or connective-tissue disease, are reported. The ratio of women to men is 4 : 1, with no apparent age specificity. The duration of the disease has been up to 16 years, with an average of seven acute episodes per year, lasting up to 14 days. Upper-airway angioedema has been severe in four patients. Routine laboratory studies were normal, as were studies of complement levels, and both humoral and cellular immunity. Two samples of synovial fluid from one patient contained a marked preponderance of Ia-positive macrophages. The absence of associated infection and connective-tissue disease suggests this recurrent triad represents a distinct entity, which is designated the AHA syndrome.
