    Notes: Summary Bullous pemphigoid (BP) is characterized by autoantibodies against 230- and 180-kDa hemidesmosomal antigens located in the most superficial layers of the basement membrane zone (BMZ). Histologically. there is a predominance of eosinophils in the infiltrate. In a psoriatic patient, we identified an unusual autoimmune subepidermal bullous eruption which clinically resembled BP, but which was characterized by IgG autoantibodies against a novel 200-kDa lower lamina lucida component, Histologically there was a predominance of neutrophils in the infiltrate.Direct immunofluorescence showed linear immunoglobulin (Ig)G and C3 deposition at the BMZ. The patient's IgG autoantibodies bound exclusively to the dermal side of salt-split normal human skin. Indirect immunogold electron microscopy showed a marked deposition of IgG at the lower lamina lucida and minimal deposition at the hemidesmosomes. Immunoblot analysis identified a unique 200-kDa autoantigen in dermal extracts and a faint band of the 230-kDa BP antigen in epidermal extracts. The patient responded dramatically well to cyclosporin A.Although the patient's serum also reacted slightly with the 230-kDa BP antigen, there were significant findings different from the usual immunopathological changes of BP. These included finding a novel 200-kDa lower lamina lucida target antigen, the binding of IgG autoantibodies exclusively to the dermal side of the split skin and a predominance of neutrophils in blister infiltrate. The IgG autoantibodies against the 200-kDa lamina lucida target antigen seemed to play a major role in the pathogenesis of this unique autoimmune subepidermal dermatosis.

    Notes: HMB-45 is a monoclonal antibody specific for melanoma cells and premature developing melanocytes. We examined the expression and specific subcellular binding sites of HMB-45 in various types of melanocytes including epidermal melanocytes from fetuses and infants with or without tyrosinase-negative oculocutaneous albinism (type IA), melanin-producing and non-producing melanoma cell lines (G361 and MeWo), and in vivo melanoma cells (melanotic and amelanotic malignant melanoma). Subcellular HMB-45 binding was examined by using post-embedding immunogold electron microscopy with rapid freezing and freeze substitution fixation methods without the use of chemical fixatives to preserve the intracytoplasmic delicate antigen property of HMB-45. HMB-45 antigen was detected not only in in vivo melanoma cells and normal fetal melanocytes, but also in melanocytes in the other conditions. Post-embedding immunogold electron microscopy revealed that HMB-45 antigen was exclusively localized to stages I and III melanosomes in the melanocytes from fetuses and infants. In tyrosinase-negative oculocutaneous albinism, only stages I and II melanosomes were detected in the cytoplasm, but both stages of melanosomes were HMB-45 positive.We conclude that HMB-45 appears mainly on the immature melanosomes during melanogenesisin both neoplastic and non-neoplastic melanocytes regardless of their tyrosinase activity, but the intracytoplasmic localization of HMB-45 antigen is different by each condition of melanocytes.

    Notes: Summary A 59-year-old male showed acquired. mechanically induced, scarring blisters on the fingers, toes, scalp and abdomen, as well as in the oral cavity. Ultrastructural and immunohistochemical examination of the bullae revealed junctional epidermal-dermal separation and lgG deposits in the lamina lucida of the basement membrane zone (BMZ). where the reactivity of the 19-DKJ-1 monoclonal antibody was decreased. Anti-BMZ autoantibodies detected in his serum were reactive to the lower lamina lacida region of normal human skin. SDS-PAGE of affinity purified antigens from human keratinocytes with IgG from the patient's serum revealed three polypeptide bands at 165, 135 and 1OO kDa. in reduced condition. The indirect immunofluorescence test of his serum was negative on skin cryosections from patients with lethal junctional epidermolysis bullosa. Pretreatment of normal human skin sections with the patient's serum, blocked the binding of 19-DEJ-1 monoclonal antibody but not that of the GB3 monoclonal antibody. This case is considered to be an acquired autoimmune bullous dermatosis due to an autoantibody reaction against uncein (19-DEJ-1 antigen). a component of anchoring filaments.

    A case of linear IgA buUous dermatosis with IgA anti-type VII collagen autoantibodies (1996)

    Notes: Summary In this study we present a patient with the sublamina densa type of linear IgA bullous dermatosis (LABD). with IgA autoantibodies reactive with the 290-kDa type VII collagen (the epidermolysis bullosa acquisita (EBA) antigen) and with immunoblotting of normal human dermal extracts. The clinical and histological features of the present case were compatible with those of LABI) but quite different from those of RBA. Although EBA sera reacted with the bacterial fusion protein of the N-terminal globular (NC1) domain of type VII collagen, this patient's serum did not show reactivity. Furthermore, ultrastructural localization of target epitopes on the anchoring fibrils in this patient was considerably different from EBA. These results indicate that, whereas EBA antibodies react with the NC1 domain of type VII collagen, the epitope in this case is different from that of EBA (and is most likely on the central triple helical domain). This difference may be responsible for the clinical presentation in this patient being distinct from that of EBA.

    Notes: Summary A patient with epidermolysis bullosa acquisita (EBA). who has been diagnosed as having bullous pemphigoid for 7 years, is reported. By immunoblotting, both the latest serum and a 4-year-stored serum sample of the patient, were shown to react with the 290-kDa EBA antigen or type VII collagen, but not with bullous pemphigoid antigens. Pre-embedding immunogold electron microscopy demonstrated that the serum bound to the ‘anchoring plaque’ and to both ends of the anchoring fibrils in the fashion reported previously. In contrast, postembedding immunoelectron microscopy showed binding mainly to the lamina densa. These results indicate that EBA antigens are localized mainly at the lamina densa. Further studies are necessary for confirmation.

    Notes: Summary The calcitonin gene-related peptide (CGRP), a known potent intrinsic cerebral vasodilator, is contained in the sensory nerves from trigeminal ganglia that inervate the cerebral arteries. We previously reported that human α CGRP (hCGRP) dilates spastic cerebral arteries after experimental subarachnoid haemorrhage (SAH) in rabbits. In the present study, we investigated the prophylactic potential of a sustained higher cerebrospinal fluid level ofhCGRP against experimental cerebral vasospasm. AnhCGRP slow-release tablet (hCGRP s-r tablet) was developed for cisternal implantation. Experimental SAH was induced by percutaneous cisternal injection of autologous arterial blood. Angiography was initiated on day 1 (before SAH) and performed everyday. ThehCGRP s-r tablet was implanted into the cisterna magna on day 2 in the treated groups. The spastic response of the basilar artery was maximized on day 4 in the non-treated (80.7% of day 1) and the placebo-treated (79.3%) groups. In contrast, the arterial diameters on day 4 were 96.1% and 90.5% of day 1 in the groups implanted withhCGRP 24 μg and 153 μg s-r tablets, respectively. We also measured the concentration ofhCGRP in the cerebrospinal fluid (CSF) following implantation of thehCGRP 24 μg s-r tablet in the cisterna magna. The hCGRP concentration before implantation was below the dectable level. Following implantation, thehCGRP level in the CSF was 23.12 nmol/L on the second day and remained at elevated levels until the fifth day. These experiments suggest that the intrathecal single implantation of thehCGRP s-r tablet could produce an elevated concentration ofhCGRP in the CSF over five days and have prevented the cerebral vasospasm after SAH in the rabbit. ThehCGRP s-r tablet may be clinically applicable in the treatment of patients with SAH against cerebral vasospasm.

    Notes: Abstract  Although recent studies have shown that various stress can induce metallothionein (MT) synthesis in animal tissues, the induction of MT synthesis by exposure to static magnetic fields (SMF) has not been reported. We measured MT levels in the liver, kidney and brain of mice exposed to SMF and also evaluated the effect of SMF exposure on the induction of hepatic MT by treatment with carbon tetrachloride (CCl4). The MT content in the liver was significantly increased by exposure to 4.7 T of SMF for 6, 24, or 48 h, whereas that in the kidney or brain was not changed compared to the control. The combination of CCl4 injection and SMF exposure induced elevation of the hepatic MT content exceeding that induced by either treatment alone. These results indicate that exposure to the strong SMF induces MT synthesis in the liver in mice and enhances the hepatic MT synthesis induced by CCl4 administration.

    Genetic basis of the neurovirulence of type 1 polioviruses isolated from vaccine-associated paralytic patients (1996)

    Notes: Summary We examined four type 1 polioviruses isolated from the stools of patients with vaccine-associated paralytic poliomyelitis in China. All of these isolates were shown to be Sabin derived viruses by restriction fragment length polymorphism assay after polymerase chain reaction and by sequencing of the viral genome encoding the viral coat protein, VP1. However, the same analysis of the 3D coding region suggested that two of the four isolates had the sequence of wild type poliovirus in the tested region. Furthermore there were also point mutations in the 5′ non-coding region. One was a single base change from U to C at nucleotide position 525, and the other three were from G to A at position 480. All the four strains were more neurovirulent than Sabin type 1 virus in transgenic mice with human poliovirus receptor gene. The data showed that the nucleotide positions of type 1 poliovirus which were identified to be in favor of the high neurovirulence were indeed changed during natural transmission, and suggested that the point mutation alone or a recombination of the vaccine type with wild type genome results in an acquisition of neurovirulence.
