Published 1981Staff ViewISSN: 1365-3083Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: The sera of ten Egyptian men with long-standing lepromatous leprosy (LL) (mean duration 17.4 years) that had failed to respond in dapsone treatment were shown to inhibit mitogen stimulation responses of normal human lymphocytes. When first tested, the sera partly inhibited the response to phytohaemagglutinin (PHA) and pokeweed mitogen and virtually abolished that to concanavalin A (Con A): after repeated freezing and thawing, the Con A inhibition had disappeared, whereas the PHA response was still partly Inhibited. The inhibitory serum factor(s) had similar actions on lymphocytes from each of six normal donors. Although the sera varied in potency, they showed similar dose response curves when tested against lymphocytes from a single donor. The principal action of the sera was to reduce the number of cells responding to mitogen, without modifying the kinetics of recruitment or rate of volume growth during G1-phase in those cells that were unaffected by the inhibitory substances(s). Study of PHA dose-response curves and of the effect of delayed addition of LL serum suggested that the serum factor(s) act by diminishing the responsiveness of the cells, rather than by reducing the concentrations of free mitogen or by blocking cell membrane mitogen receptors The serum from one apparently healthy attendant, who had nursed leprosy patients for 30 years but who did not have leprosy or other chronic infective disease, inhibited completely stimulation by all three mitogens in a manner different from that of LL sera. Serum from the other 13 control patients did not modify the response of normal lymphocytes to stimulation by any of the three mitogens studied. It was concluded that the inhibitory factor(s) in the scrum of patients, with LL were a consequence of the disease and not of the environment in which the patients lived. Microscopy confirmed that the techniques used for recovery of the cultured cells did not introduce bias into the volume spectroscopy measurements.Type of Medium: Electronic ResourceURL: -

Published 1989Staff ViewISSN: 1365-3083Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: The relationship of velocity of blood flow to density and microanatomical distribution of inflammatory cells in the dermis was studied in 20 human tuberculin tests. Must positive reactions showed maximal blood flow velocities (measured as red blood cell (RBC)flux) at the centre of the reaction, but the two most intense responses showed ‘central relative slowing’(CRS) with higher RBC flux at she periphery. Two of the four clinically negative reactions showed a considerable acceleration of blood flow, but the other two showed no such acceleration. The packing density of lymphocytes/monocytes in the perivascular zone was greater in the stronger positives than in the weaker reactions. The density of cells in the intervening dermis was markedly lower than in the foci: the lesions with CRS had the highest density of cells in the diffuse infiltrate of the reticular dermis. At the centre of the reaction, blood flow velocity was generally related to density of cellular infiltrate, except in those with CRS, which had a disproportionately lower blood flow velocity. The finding that the circulatory adaptation to a delayed hypersensitivity reaction can be inadequate may explain the dermal acidosis previously observed in intense skin test reactions, and may be the underlying mechanism of necrosis in hypersensitive reactions.Type of Medium: Electronic ResourceURL:
