OBJECTIVE To develop a disease specific measure of quality of life for application in children with juvenile rheumatoid arthritis and juvenile spondyloarthritides-the Juvenile Arthritis Quality of Life Questionnaire (JAQQ). METHODS Patients and their parents were interviewed by a trained interviewer using a questionnaire focusing on physical function,(More)
OBJECTIVE Neurologic and psychiatric manifestations are severe complications of systemic lupus erythematosus (SLE). As commonly seen in patients, spontaneous development of lupus-like disease in MRL-lpr mice is accompanied by brain atrophy and behavioral dysfunction. We examined inflammatory and ultrastructural aspects of central nervous system (CNS)(More)
A transgenic mouse containing 70 copies (ND4) of the transgene encoding DM20, a myelin proteolipid protein, appeared clinically normal up to 3 months of age. By 8-10 months, it showed tremors, unsteady gait, and died shortly thereafter. We concluded that the clinical symptoms correlated with demyelination based on the following criteria: 1) at 10 months of(More)
BACKGROUND Two strains of guinea pig develop spontaneous osteoarthritis of the knee. Although the disease evolves at different rates in the two strains, it is not known whether these differences are reflected in the structure of the cartilage and cancellous bone. QUESTIONS/PURPOSES We determined whether the three-dimensional structure of the(More)
Poly(epsilon-caprolactone) (PCL) microspheres containing taxol were prepared by the solvent evaporation method and tested for angiogenesis inhibition using the chick chorioallantoic membrane (CAM) model. Very high encapsulation efficiencies (95%) for taxol in PCL microspheres were obtained. In vitro release studies showed about 25% of the loaded drug was(More)
Using vanadyl sulphate, sodium orthovanadate or bis(maltolato)oxovanadium (BMOV), Cruz TF, Morgan A, Min W (1995, Mol Cell Biochem 153: 161-166) have recently demonstrated the antineoplastic effects of vanadium in mice. In this study, the antineoplastic effects of BMOV against human tumour cell lines was confirmed, and this effect was shown to depend on the(More)

OBJECTIVE To determine the level of agreement between parents and children in rating dysfunction in juvenile rheumatoid arthritis (JRA) and juvenile spondyloarthritides. METHODS We conducted separate interviews (parents and patients) of children > or = 9 years of age with JRA and spondyloarthritis attending our clinic. A questionnaire consisting of 100(More)
OBJECTIVE Collagen induced arthritis (CIA) is a model of chronic inflammatory synovitis with pannus, neovascularization, and joint destruction similar to rheumatoid arthritis (RA). Matrix metalloproteinases (MMP) are involved in degradation of the extracellular matrix and joint destruction in RA. c-fos and c-jun are protooncogenes whose products combine to(More)
OBJECTIVE To determine whether children with juvenile rheumatoid arthritis (JRA) express cellular immunity to cartilage link protein. METHODS Link protein was purified from human fetal epiphyseal and bovine adult nasal cartilage. It was used in proliferation assays with the peripheral blood lymphocytes isolated from 54 children with JRA and 22(More)
