The anti-malarial drug chloroquine (CQ) is also thought to be a potential radiation sensitizer. To gain a better understanding of how the lysomotropic CQ can potentiate the effects of ionizing radiation, we investigated the effects of CQ on lysosomal and mitochondrial membrane stability, the
Although chloroquine administration in vivo following haemorrhage in mice decreases tumour necrosis factor-alpha (TNF-alpha) release by macrophage (M phi), the mechanism remains unknown. To study this, peritoneal M phi (pM phi) from unmanipulated, sham-operated and post-haemorrhage mice were
Hemorrhagic shock suppresses the ability of Kupffer cells (KC) to present antigen and express the major histocompatibility complex class II (Ia) antigen. These alterations are concomitant with an enhanced release of cytokines (tumor necrosis factor [TNF], interleukin-1 [IL-1], IL-6) and
BACKGROUND
Plasmodium yoelii nigeriensis (P. y. nigeriensis) produces lethal malaria infection in Swiss albino mice. Tumor necrosis factor (TNF) has been implicated in the pathogenesis of malaria by production of reactive oxygen species. Chloroquine is a traditionally used antimalarial and has been
Proinflammatory cytokine tumour necrosis factor (TNF) mediates its diverse effects through cell surface receptors. A variety of inflammatory signals are known to modulate TNF activities by changing expression and shedding of cell-surface TNF receptors. We have examined the effects of anti-rheumatic
OBJECTIVE
The efficacy of both chloroquine and hydroxychloroquine in rheumatoid arthritis (RA) has been proved in controlled clinical trials. Despite similar chemical characteristics, it is believed the clinical efficacy of chloroquine is superior to that of hydroxychloroquine in patients with RA.
TNF, a potent immunoregulatory cytokine, is associated with inflammatory diseases such as rheumatoid arthritis, multiple sclerosis, and cerebral malaria when produced in excess. Antimalarial agents such as chloroquine and hydroxychloroquine have been used to treat some rheumatic diseases.
Post-transfusion graft-versus-host disease (PT-GVHD) is a fatal adverse effect of blood transfusion. In spite of its severity, there is no effective treatment at present for PT-GVHD. Previously, we reported that chloroquine (CH) inhibited the cytotoxicity of cytotoxic T-cell (CTL) clones and tumour
Severe radiation reaction with chest wall necrosis occurred following 5,000 rads of 60Co irradiation. The patient was arthritic and on chloroquine therapy. This delayed reaction was due to chloroquine radiosensitization. Rats treated with combined chloroquine and chest wall irradiation were compared
Chloroquine is widely used as self-medication for presumptive treatment of malaria despite the existence of parasite resistance to the drug. Recent studies suggest that tumour necrosis factor-alpha (TNF-alpha) overproduction probably has a causal association with poor outcome in cerebral malaria. In
Chloroquine, due to its basic properties, has been shown to prevent the release of iron from holotransferrin, thereby interfering with normal iron metabolism in a variety of cell types. We have studied the effects of chloroquine on the evolution of experimental paracoccidioidomycosis by evaluating
This prospective study contains clinical and experimental parts. In the clinical study, 125 patients given intramuscular chloroquine for malaria were followed for 2 months in order to detect local injection site complications. Adequate local antiseptic conditions were ensured before giving the
Anemia is a common and serious complication of malaria due to Plasmodium falciparum infection, a major health problem in tropical areas. Herein, the relation was investigated between the levels of circulating erythropoietin (EPO) and immunomodulatory cytokines in response to chloroquine treatment.
Chloroquine (CQ) is an antimalarial drug that elicits severe pruritus in black Africans with malaria fever. This acute itching (2-7 days duration) exhibits age dependency and a racial and genetic predilection. CQ itch is non-histaminergic, which makes it both a good model and a tool to probe the
