An application of the Southern blot technique is described which permits the detection of DNA fragmentation due to cell death by apoptosis. DNA fragments were isolated from cell suspensions and tissues, separated on agarose gel, transferred by Southern blot and hybridized with a radiolabeled total cellular DNA probe. The application of this procedure to(More)
The H-2 restriction phenomenon was evaluated with regard to the immune response to Moloney sarcoma virus (M-MSV)-induced tumours in the mouse. Using an in vitro 51Cr release assay the lytic activity of lymphocytes from M-MSV immune strains of mice, including several H-2 recombinant strains, was determined on leukaemic cell lines originally induced in mice(More)
In this study, we evaluated pain sensitivity in patients with fibromyalgia or other types of chronic, diffuse musculoskeletal pain to establish whether fibromyalgia represents the end of a continuum of dysfunction in the nociceptive system. One hundred and forty five patients and 22 healthy subjects (HS) completed an epidemiological questionnaire to provide(More)
Gonadal hormones are known to be affected by morphine and other opioids. In this paper, we summarize data collected in recent years which clearly indicate that the opioid-induced effects on steroid hormones depend on the opioid used and in some cases on the sex of the subject. Indeed morphine is able to reduce hormones like testosterone and cortisol in both(More)
OBJECTIVE Alexithymia, a lack of emotional awareness, is common in chronic pain patients. The aim of the study was to investigate the relationship of alexithymia to ongoing pain, experimental pain sensitivity, and illness behavior in patients with chronic musculoskeletal pain. METHODS Sixty-eight women with fibromyalgia (age: average, 43.4 years; range,(More)
OBJECTIVE To date, few results on well-being in chronic-pain patients have been published, while several studies in patients without pain have indicated that well-being may not be equivalent to absence of psychological distress. The aim of the present study was to investigate the relationship between psychological distress and well-being and to identify the(More)
We analysed longitudinally the numbers of CD3-CD16+ (natural killer cells, NK) and CD3-CD57+ cells (a subset of NK) in 15 IFNbeta1b- and 12 IFNbeta1a-treated relapsing-remitting multiple sclerosis (RRMS) patients. IFNbeta1b (Betaferon)-treated RRMS patients showed a rapid and marked reduction in the number of both NK subsets which started 1 month after(More)
We analysed the role of dosage, route and frequency of administration of clinical grade interferon-beta (IFN-beta) preparations in inducing anti-IFN-beta antibodies (IFN-beta-Abs) in 5 groups of relapsing-remitting multiple sclerosis (RRMS) patients who were respectively treated as follows: 1) weekly intramuscular (i.m.) injections of 30 mg of recombinant(More)
Linear scleroderma (LS) is characterized by scleroatrophic lesions affecting limbs and legs, unilaterally. Neurological involvement may be associated with ipsilateral facial and skull involvement in disorders referred to clinically as LS 'en coup de sabre', and Parry-Romberg syndrome. We report a child with LS presenting with a severe neurological disorder(More)
The role of Ia-positive accessory cells in the generation of a secondary cytotoxic response to tumor-associated antigens induced by Moloney murine sarcoma virus (M-MSV) was evaluated. Spleen cells from M-MSV-immune A.TL mice, depleted of accessory cells by anti-Iak serum plus C treatment and stimulated in secondary mixed leukocyte tumor cell culture (MLTC)(More)
