    Notes: Summary As a result of a genetic analysis of 63 third chromosome suppressor mutations of position-effect variegation 12 different loci showing dominant suppression have been identified and their map positions determined. A compilcation of the genetic data available for each suppressor locus is given. The strong suppressor effects of the mutations have been quantified by measurements of white variegation inw m4h /w m4h ,w m4h /Y andw m4h /O flies. Mutant alleles of three loci were found in these studies to dominate over the strong enhancer effect of complete loss of the Y chromosome. Most of the identified loci suppressing position-effect variegation represent essential genetic funtions; only three loci represent nonessential functions. Mutations of two loci display recessive butyrate sensitivity and lethal interaction with the heterochromatic Y chromosome suggesting that these genes affect chromosomal condensation. Studies with deficiencies and triploids revealed that most of the loci represent haplo-abnormal suppressor functions. The use of the isolated mutant material for genetic, developmental and molecular studies of processes connected with gene inactivation in position-effect variegation is discussed.

    Notes: Abstract Factor XIII (FXIII) links soluble fibrin monomers and collagen fibres to stable fibrin connections. Deficiency of FXIII, caused by dyspoiesis or increased consumption, results in a bleeding tendency and wound healing complications. Although the decrease of FXIII and successful replacement in patients with wound healing complications after surgery have been described by several authors, it is rarely considered that patients with autoimmune diseases, bleeding or healing complications may suffer from FXIII deficiency. We report a patient with severe psoriasis vulgaris generalisata with large, painful erythemas, bleeding tendency, joint contractions and infirmity, whose FXIII activity was 19%. After successful replacement the bleeding tendency vanished, and a marked improvement of skin and joint mobility allowed mobilisation and administration of physical therapy, whereby some independence and mobility were restored to the patient.
