[Ataxic sensory and autonomic neuropathies associated with primary Sjögren's syndrome: a case report].

A 49-year-old woman had xerostomia and foreign body sensation of eye since 27 years old. Since the age of 30 she developed occasional fever attack released by cooling body without medication. Three years later she began to complain difficulty to maintain standing position with closed eyes.

[Clinical evaluation of quantitative measurement of various antinuclear antibodies by enzyme immunoassay].

Quantitative analysis of several antinuclear antibodies (ANAs) by enzyme immunoassay (EIA) has been developed and widely used. Among them, the EIA coating fragmented HEp-2 cells nuclei is a new approach for quantitating the amount of total ANAs. The EIA to detect IgG anti double-stranded DNA antibodies (dsDNA-EIA) is a highly sensitive method, but less sensitive compared with radioimmunoassay (Farr's assay) which detects anti dsDNA antibodies of total immunoglobulins.

[Clinical application of anti double-stranded and single-stranded DNA antibodies measurements by enzyme-linked immunosorbent assay (ELISA) using E. coli plasmid DNA].

Anti double-stranded (ds) and single-stranded (ss) DNA IgG antibodies were detected in patients with various connective tissue diseases by RECOMBIGEN ELISA Anti ds-DNA Kit and ELISA Anti ss-DNA Kit (Nippon DPC Co) using E. coli plasmid DNA. High levels of anti ds-DNA and anti ss-DNA antibodies were mostly found and distributed in patients with systemic lupus erythematosus(SLE) and allied disorders.
