    Notes: We describe a rare case of pemphigus foliaceus associated with familial myasthenia gravis (MG). A 35-year-old woman developed MG during oral corticosteroid treatment for pemphigus foliaceus. She had been operated on for a thyroid gland tumour that was confirmed histopathologically to be papillary carcinoma without metastasis. At the time of treatment, her mother had had MG for 30 years and undergone thymectomy 22 years ago. A specific ELISA technique showed that antidesmoglein 1 antibody was present in the daughter. There are many reports of multiple diseases such as pemphigus, thymoma, malignancy, and other autoimmune diseases associated with MG. However, familial MG following pemphigus foliaceus has not been reported previously.

    Notes: Abstract It has been demonstrated that the administration of CTLA4Ig protein can induce the suppression of allograft and xenograft rejection. The purpose of this study is to determine the effect of adenovirus-mediated gene transfer with CTLA4Ig gene on the transgene expression and suppression of alloimmune response in allogeneic cardiac transplantation of rats. Adenoviral vectors with β galactosidase or human CTLA4Ig cDNA (Adex/LacZ, Adex/hCTLA4Ig) were constructed. These vectors were transduced to the liver of Lewis (LEW) rats by intravenous injection. Then LEW rats received heterotopic cardiac transplantation from Dark Agouti rats. Experiments were performed using both CTLA4Ig gene transduction and/or immunosuppressant FK506. The transgene expression after adenovirus-mediated transfer with CTLA4Ig cDNA lasted for several months, compared with several weeks after that in controls, which was proportional to the blood concentration of CTLA4Ig protein. By the administration of 1 × 109 PFU of Adex/hCTLA4Ig, the survival of cardiac grafts was significantly prolonged, compared with controls or the use of 1 × 108 PFU of Adex/hCTLA4Ig. In the rats with beating grafts over 100 days, the blood concentrations of CTLA4Ig were undetectable. The combination therapy using a low titer Adex/hCTLA4Ig and low-dose of FK506 was synergistically effective on this cardiac transplantation model. In conclusion, adenovirus-mediated gene transfer with CTLA4Ig gene was efficient for the prolongation of both transgene expression and allograft survival.

    Notes: Abstract Preeclampsia is associated with thrombosis of the intervillous or spiral artery. A deletion/insertion polymorphism (4G or 5G) in the promoter of the plasminogen activator inhibitor type 1 (PAI-1) gene is suggested to be involved in regulating the synthesis of the inhibitor, 4G allele, being associated with the enhanced gene expression and plasma PAI-1 levels. We assessed the association between preeclampsia and the 4G/5G polymorphism of the PAI-1 gene in 115 preeclamptic patients, 210 pregnant controls, and 298 healthy volunteer controls. The frequency of the homozygotes for the 4G allele was significantly higher in the patients than in the control pregnant women (P = 0.04) or in the healthy volunteers (P = 0.02). The 4G allele frequency was also significantly higher in the patients than in the control group of pregnant women (P = 0.03) and in the healthy volunteers (P = 0.02). These results suggest that the presence of the 4G/4G genotype of the PAI-1 gene is one of the risk factors for preeclampsia.
