background: various compounds of plant origin have been widely investigated since ancient times for their possible immunomodulatory properties as well as for the treatment of a wide range of diseases. objective: to study the immunomodulatory functions of the aqueous extract of the seeds of abrus precatorius commonly known as indian liquorice (fabaceae), a medicinal plant native to central india...

in this study, immune responses against streptococcus iniae infections in rainbow trout (oncorhynchus mykiss) were analyzed. anti-streptococcal antibody (asa) levels, respiratory burst activity (rba), phagocytic activity (pa) and phagocytic index (p index) were measured in kidney macrophages. fish were allocated to three experimental groups (n = 50 per group): survivors of natural s. iniae inf...

The main aim of this study was to compare selected nonspecific immunity parameters in 14 allergic and 12 healthy horses. Each animal was assessed according to the following parameters: in vitro functional capacity of phagocytic cells using the nitro blue tetrazolium chloride reduction test, both spontaneous (NBT) and zymozan stimulated (NBTs), and ingestion capacity of phagocytic cells using a ...

OBJECTIVE Macrophages are an important reservoir for the HIV and contribute to innate lung defense by their ability to phagocytose, digest, and process invading pathogens. We hypothesized that HIV-1 infection may lead to a defect in the phagocytic activity of alveolar macrophages. DESIGN In order to test this hypothesis, the phagocytic activity of alveolar macrophages from asymptomatic HIV-1 ...

Macrophages ingest the fungus Cryptococcus neoformans only in the presence of opsonins, and this provides a remarkably clean system for the detailed analysis of phagocytosis. This system is also unusual in that antibody-mediated phagocytosis involves ingestion through both Fc and complement receptors in the absence of complement. Mathematical modeling was used to analyze and explain the experim...

BACKGROUND AND AIMS Perioperative immunonutrition can influence the phagocytic activity of platelets in advanced gastric cancer. METHODS 51 patients with stage IV gastric cancer divided into four groups depending on the clinical status and 40 normal donors were analyzed. Patients of groups I and II underwent palliative gastrectomy. Patients of groups III and IV had exploratory laparotomy. Per...

PURPOSE Granulocyte-colony stimulating factor stimulates proliferation and maturation of granulocyte precursor cells. The influence of this hematopoietic factor on phagocytic function of granulocytes was performed in in vitro experiments. The aim was to find, whether G-CSF applicated to children with neutropenia after chemotherapy influences phagocytic functions of neutrophils and whether evalu...

The phagocytic activity of the granulocytes and the mononuclear cells of the local inflammatory exÃodate of adult patients with leukemia has been studied by the skin window technic. The cells were exposed to India ink, and their phagocytic activity was expressed as percentage of cells containing particles (phagocytic index). The capability of granulocytes and mononuclear cells to engulf India i...
