Female W/Fu rats were gavaged daily with a water-soluble extract (C-MED-100) of Uncaria tomentosa supplied commercially by CampaMed at the doses of 0, 5, 10, 20, 40 and 80 mg/kg for 8 consecutive weeks. Phytohemagglutinin (PHA) stimulated lymphocyte proliferation was significantly increased in splenocytes of rats treated at the doses of 40 and 80 mg/kg.(More)
Thymidine incorporation into DNA was examined in confluent fibroblast cultures which had been further arrested by 7-9 days' growth on 0.5% serum-supplemented medium. There were 13 fibroblast lines from patients with adenomatosis of the colon and rectum (ACR) and seven control fibroblast strains from unaffected relatives and spouses of ACR patients. After 24(More)
A biological bank has been developed to extend the biochemical and molecular research base for a prospective study on diet and cancer in the city of Malmo, Sweden. The study entered individuals 45-69 years of age, of which 30,382 individuals (45%) participated. Each individual entering the bank has stored samples of viable mononuclear leukocytes (MNLs; -140(More)
Human mononuclear leukocytes (HML) respond to oxidative DNA damage by activation of ADP ribosylation and initiation of DNA repair synthesis (i.e. unscheduled DNA synthesis, UDS), whereas neutrophils do not. When neutrophils are added to HML cultures in ratios up to 4:1 ADP ribosylation becomes inhibited to approximately 50-60%. The ability of neutrophils to(More)
OBJECTIVE Regulatory T cells (Tregs) protect against atherosclerosis in experimental models, but their association with cardiovascular disease in humans remains to be elucidated. The aim of the present study was to determine whether circulating Tregs predict the development of acute cardiovascular events in humans. METHODS AND RESULTS The study cohort(More)
BACKGROUND Although monocytes in peripheral blood are no longer considered to be a homogeneous population, associations between distinct monocyte subsets and cardiovascular disease have not been highlighted in large epidemiological studies. METHODS AND RESULTS The study included 700 randomly selected subjects from the cardiovascular arm of the Malmö Diet(More)
Growth inhibitory activities of novel water extracts of Uncaria tomentosa (C-Med-100) were examined in vitro using two human leukemic cell lines (K562 and HL60) and one human EBV-transformed B lymphoma cell line (Raji). The proliferative capacities of HL60 and Raji cells were strongly suppressed in the presence of the C-Med-100 while K562 was more resistant(More)
Historic medicinal practice has defined Cat's Claw, also known as Una de Gato or Uncaria tomentosa, as an effective treatment for several health disorders including chronic inflammation, gastrointestinal dysfunction such as ulcers, tumors and infections. The efficacy of Cat's Claw was originally believed, as early as the 1960s, to be due to the presence of(More)
Four volunteers were involved for 5 weeks of a baseline period, followed by 7 weeks of a combined supplementation of nicotinamide, zinc, and carotenoids (Nicoplex). Blood sampling and bioassays were carried out every week during the evaluation period. The supplementation of Nicoplex resulted in statistically significant increased resistance to DNA(More)
Human mononuclear leukocytes were exposed to prooxidants such as H2O2, phorbol-12-myristate-13-acetate, and 4-nitroquinoline-N-oxide, and the effects on induction of DNA damage and repair were evaluated. ADP ribosylation was activated by prooxidant exposure and the response was bimodal with peaks of activation occurring at about 30 min and 4-5 h. Other(More)
