The skin is the major site on anaphylaxis, and cutaneous mast cells have an important role in its reactions. The isolation and purification of rat cutaneous mast cells are described here. Rat abdominal skin was digested with collagenase and hyaluronidase, and centrifuged with Percoll. The buoyant density of cutaneous mast cells was high, and relatively pure(More)
A 60-year-old man who had had a renal transplantation developed a nodule on the dorsum of his right middle finger, which was subsequently diagnosed as cutaneous phaeohyphomycosis caused by Exophiala jeanselmei. The patient was successfully treated with 5-fluorocytosine. To our knowledge, this case is the third reported case in the world caused by this(More)
We investigated the presence of a platelet-activating factor-like substance in blister fluid obtained from patients with bullous pemphigoid. Human platelet aggregation activity was present in blister fluids obtained from 4 out of 6 patients with bullous pemphigoid and in blister fluids obtained from 3 cases with contact dermatitis. Platelet aggregation(More)
In a distinct autosomal recessive variant of epidermolysis bullosa, EB-MD, life-long skin blistering is associated with late-onset muscular dystrophy of unknown etiology. Electron microscopy of these patients' skin suggests that tissue separation occurs intracellularly at the level of the hemidesmosomal inner plaque, which contains plectin, a high molecular(More)
FK506, a new immunosuppressive agent, is effective in treating patients with psoriasis. A major feature of psoriasis vulgaris is the hyperproliferation of keratinocytes together with inflammation. To determine the effect of FK506 or cyclosporin A (CsA) on the keratinocyte cell cycle, flow cytometry and the growth factor free normal human(More)
BACKGROUND Epidermolysis bullosa simplex associated with muscular dystrophy (EBS-MD; OMIM# 226670) is an autosomal recessive disorder caused by genetic defects in the plectin gene. Because EBS-MD is relatively rare, and gene defects have been elucidated only in a limited number of patients, the precise phenotype-genotype correlations have not yet been fully(More)
S-100 protein, isolated from mammalian brain, has widely been used for immunohistochemical marker of the glia cells and the cells derived from the neural crest. In the present study, we made anti S-100 protein antibody and studied the immunoreactive distribution of S-100 protein in the cutaneous nervous system. Albino rabbits were immunized with S-100(More)
A survey of 150 cases with sporotrichosis seen at the Dermatological Clinic of Kurume University Hospital from February 1962 to October 1986 was reported. The proportion of cases with sporotrichosis to the total number of outpatients was 0.17%. Greater percentage of cases fell into the less than 10 years old or more than 40 years old groups. The male to(More)
