We tested a range of drugs for their effects on in vitro polyclonal IgG synthesis by human peripheral blood mononuclear cells (PBMC) stimulated with the lectin pokeweed mitogen (PWM). The test drugs were selected on the basis of reported disruptive effects on immune function in vivo. IgG production between day 4 and days 7 or 8 of culture was measured by(More)
Airway inflammation is characterized by selective recruitment of mononuclear and granulocytic cells. This recruitment is mediated by the action of chemotactic cytokines, such as chemokines. A number of chemokines and their receptors have been identified and proposed as potential therapeutic agents in allergic airway inflammation. One of these chemokines is(More)
This paper describes a new method for authentication and integrity where the ciphertext is obtained using block upper triangular matrices with elements in p Z , in which the discrete logarithm problem (DLP) defined over a finite group is used. In the proposed public key cryptosystem, the encryption requires very few operations and decryption is equivalent(More)
In this study, we report that administration of Lactobacillus casei confers protection to mice against the intracellular protozoan Babesia microti. Mice treated with L. casei orally or intraperitoneally were inoculated 7 days later with an infectious dose of B. microti. Mice treated with lactobacilli showed significant reduction in the percentage of(More)
We have shown previously that chlorpromazine, a drug associated with immunological abnormalities in vivo, significantly potentiates pokeweed mitogen (PWM)-stimulated IgG synthesis by human peripheral blood mononuclear cells (PBMC) in culture. Chlorpromazine is a pharmacological antagonist of histamine and 5-hydroxytryptamine (5-HT) and thus may exert its(More)
