    Notes: Abstract The mechanisms of the elevation of serum IgA levels in anaphylactoid purpura were investigated. Serum IgA levels were significantly elevated within 2 weeks (5 to 14 days for all 12 patients) after onset in patients with anaphylactoid purpura. Serum IgM and IgG were not elevated. Although the percentages of surface IgA-bearing cells were not increased in the patients, the numbers of IgA-secreting cells within 2 weeks after onset in the patients with anaphylactoid purpura were significantly higher than those of controls. In northern blot analysis on lymphocytes, the secreted α (αs)-chain gene was well expressed compared with the membrane-bound α (αm)-chain gene, within 2 weeks after the onset of anaphylactoid purpura. Therefore, stimulation by a certain agent or a certain immune response may accelerate expression of the αs-chain gene in anaphylactoid purpura.

    Notes: Summary An interstitial deletion, del(11)(q14q22), found in a female infant was examined by fluorescencein situ hybridization with cosmid DNA markers mapped on the long arm of chromosome 11. Three cosmids mapped on 11q14.1-11q22.1 region were not hybridized to the del(11) chromosome, while all the other DNA markers mapped on 11cen-11q14.1 and 11q23.1-11 qter region gave hybridization signals on the del(11) chromosome. Cytogenetic analysis after R-banding confirmed an apparent deletion of 11q14-q22, but containing a small R-negative band, a part of 11q22.3 and/or 11q14.1, in the middle part of del(11) chromosome. The karyotype thus was determined to be 46, XX, del(11)(q14.1q22.3).

    Notes: Summary A 12-month-old female infant with developmental delay, growth retardation, and dysmorphic features including dolichocephaly, telecanthus, ptosis, flat nasal bridge, anteverted nares, high-arched palate, carp-shaped mouth, micro-retrognathia, and low-set and posteriorly rotated ears was found to have an interstitial deletion of chromosome 11 involving bands q14–q22. Immunoblot analysis of her fibroblasts revealed a normal amount of mitochondrial acetoacetyl-coenzyme A thiolase, of which gene locus has been assigned to chromosome 11q22.3–q23.1. This result suggested that the region around the boundary of 11q22.3–q23.1 was intact in this patient.
