Immunotherapy is divided into two overlapping categories, active and passive. The goal of active immunotherapy is the stimulation of host ant ¡tumorimmunity, either cellular or hu moral. This can be accomplished in a direct or specific fashion by using tumor vaccines to generate an immune response to tumor-associated antigens. Nonspecific antitumor immunity can be propagated by compounds such ...

Acute stress can compromise acquired, and potentiate innate, immunity. Recent evidence suggests that the impact of stress on measures of immunity can be modulated by the physical activity status of the organism and that extracellular heat shock protein 72 (eHSP72) contributes to the activation of innate immunity produced by stress. Therefore, this study investigated whether physical activity st...

based on experiments showing immunomodulatory effects of garlic (allium sativum l.), we sought to see whether allium hirtifolim boiss., belonging to the same genus of garlic, has any effect on immune responses. hydroalcoholic extract and polyphenolic fraction of a. hirtifolium bulbs were prepared. allicin (diallyl thiosulfinate), a biologically active component, was identified in plant bulbs by...

1. Considerable variation in the resistance of different rats toward Type II pneumococcus has been demonstrated. In general, older rats survive much greater doses than young ones, illustrating the acquisition of a natural partial immunity. The same is true for Type III but the immunity appears somewhat later in life and does not reach the same height. 2. An active immunity can be created agains...

exposure to high dosages of sulfur mustard (sm) can cause bone marrow depression, immune system suppression, impairment of the immune functions, and eventually results in diseases due to secondary immune disorders. in this article, we have studied the effects of this poison on iranian veterans by analysis of related published studies. in a systematic search, the effects of sm gas on iranian vic...

objective: hypericum perforatum (st. john's wort) has long been used in traditional medicine to treat a variety of internal and external ailments. the present study was done to evaluate the immumodulatory potentials of the hydroalcoholic extract of h. perforatum. materials and methods: twenty male balb/c-mice were randomly allocated in two equal groups and immunized with sheep red blood ce...
