Cell-mediated immunity was evaluated in 28 patients with malignant glioma, using in vivo and in vitro tests of lymphocyte function. The results were compared to those found in patients with carcinomatosis (11 subjects), benign brain tumours (9), other neurological disorders (20) and normal, healthy controls (21). Significant impairments of delayed(More)
An attempt was made to correlate lymphocyte subset abnormalities with the development of experimental autoimmune thyroiditis (EAIT) in thymectomized and irradiated rats of five inbred strains. The peripheral blood subpopulations were analysed using the fluorescence-activated cell sorter (FACS-IV). A significant lymphopenia with a severe decrease in helper T(More)
The mutagenicity of 2-acetylaminofluorene (AAF) in S. typhimurium TA 1538 was investigated using Ames' test and activation systems based upon rat- or cotton rat-liver post-mitochondrial supernatant (S9) fractions. Part of this study involved sub-fractionation of S9 into microsomes (M) and 100,000 X g supernatant (S100) fractions. With a rat liver-derived(More)
Male BXSB mice develop murine lupus spontaneously at about 3 months of age. Polyclonal B-cell activation is thought to play a major role in the development of the syndrome in these mice, but the immunological events which lead to this activation are not known. We therefore examined the immune characteristics of mice aged 10-16 weeks, at the onset of(More)
Mice of the genetically different BXSB and MRL/lpr strains develop murine lupus spontaneously at about three months of age. Polyclonal B-cell activation is thought to play a major role in the development of the syndrome in each strains, but the immunological events which lead to this activation are not known. We therefore examined the immune characteristics(More)
A functional for the cumulant energy is introduced. The functional is composed of a pair-correction and static and dynamic correlation energy components. The pair-correction and static correlation energies are functionals of the natural orbitals and the occupancy transferred between near-degenerate orbital pairs, rather than the orbital occupancies(More)
