Cannabinoids affect immune responses in ways that may be beneficial for autoimmune diseases. We sought to determine whether chronic Cannabis use differentially modulates a select number of immune parameters in healthy controls and individuals with multiple sclerosis (MS cases). Subjects were enrolled and consented to a single blood draw, matched for age and(More)
BACKGROUND Over 50% of adults currently use dietary supplements (DS) but manufacturers do not have to prove the safety or efficacy of a DS before it is marketed. Therefore, consumers may be exposed to inaccurate DS information, may lack confidence in choosing appropriate DS and may seek advice for usage. The objective of this study was to examine trends in(More)
We investigated the influence of tuftsin partial sequences (Thr-Lys, Lys-Pro, Lys-Pro-Arg and Pro-Arg) on histamine concentration in selected tissues (lungs, kidneys, liver, duodenal wall and arterial blood) of guinea-pigs and rats. The peptides were administered in 1 mg/kg dose intravenously (single dose) or intraperitoneally (single dose or three doses at(More)
The performed studies covered the effect of tuftsin, tetrapeptide stimulating many components of immunological reactions, to histamine concentration in lungs, kidneys, liver, duodenum as well as in the blood of rabbits and guinea-pigs. Tuftsin was given intravenously in a single injection (0.5 mg/kg), and for guinea-pigs also in one-hour infusion (1.0(More)
The performed studies dealt with the effect of tuftsin (tetrapeptide Thr-Lys-Pro-Arg), a stimulator of many components of immunological reactions, exerted on histamine concentration in lungs, kidneys, liver, duodenal wall and arterial blood of guinea-pigs. Tuftsin was given intraperitoneally, in a single dose (0.5 and 1.0 mg/kg) or three times at one-hour(More)
