Autoantibodies to nucleosomal proteins: antibodies to HMG-17 in autoimmune diseases.

The relative amounts of autoantibodies against defined nucleosomal proteins present in serums from patients with systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and mixed connective tissue disease (MCTD) have been examined by an enzyme-linked immunoassay. Autoantibodies to nucleosomal proteins were detected in 45 percent of the patients with SLE, 18 percent of the MCTD patients, and none of the RA patients. The results suggest that, in SLE, antibodies are formed against a subset of nucleosomes which contain protein HMG-17.

Effects of pressure on cerebrospinal fluid formation: nonsteady-state measurements in dogs.

Effects of pressure on cerebrospinal fluid (CSF) formation were studied in dogs with a recirculatory spinal perfusion tracer clearance technique that does not require steady-state conditions. The data permit statistical analysis of the relationship between the rate of CSF formation and pressure for individual animals. Most animals showed no statistical relationship between CSF formation and intracranial pressure (ICP) and/or cerebral perfusion pressure (CPP). In this study, a disturbance of cerebral blood flow (CBF) autoregulation may have been present in five animals on the basis of CPP reductions, and four of this latter group showed formation to decrease with increasing ICP. It is suggested that CSF formation is normally pressure insensitive. With impaired autoregulation of CBF, formation may follow CBF and CPP passively.

Nitrosamines in new automobiles.

The volatile nitrosamines, N-nitrosodimethylamine (NDMA), N-nitrosomorpholine (NMOR), N-nitrosodiethylamine (NDEA) and possibly N-nitrosodibutylamine (NDBA) have been found to be present as airborne pollutants in the interiors of new (1979 model) automobiles. In the 38 automobiles tested, the levels ranged from 0.07 to 0.83 micrograms/m3 (average 0.3 micrograms/m3) for NDMA, from 0.07 to 2.5 micrograms/m3 (average 0.67 micrograms/m3) for NMOR, from 0.04 to 0.39 micrograms/m3 (average 0.11 micrograms/m3) for NDEA and trace levels (less than 0.01 micrograms/m3) for NDMA.
