background: holothuroids (sea cucumbers) are members of the phylum echinodermata, which produce saponins. saponins exhibit a wide spectrum of pharmacological and biological activities. in this study, we isolated the crude saponins from the body wall of the dominant iranian species of sea cucumber, holothuria leucospilota (h. leucospilota). the purpose of this study was to confirm the presence o...
sions of new or recrudescent acute synovitis. RF-PFC were observed to disappear from the peripheral circulation and the bone marrow during therapy with cytotoxic drugs. The data are consistent with the hypothesis that the appearance of RF-PFC in the peripheral blood represents an anamnestic response to transiently appearing antigen. The nature of the antigen is not specified. The bone marrow ma...

Introduction: Cervical cancer is the second prevalent cancer in developing countries and the sixth prevalent cancer in USA. Since conventional treatment methods are associated with detrimental side effects, searching for new drugs using natural ingredients is very important. Previous studies have shown that melittin (main component of honey bee venom) has anticancer properties along with the ef...
Background: Gastric cancer (GC) is one of the most common cancers worldwide and in Iran. Conventional therapies are surgery and chemotherapy. Current studies are evaluating natural compounds in inhibiting growth of cancer cell. In this study isolated peptide melittin with 26 amino acids from bee venom and its impact on the viability and proliferation of gastric cancer cells was investigated. Me...
We previously described a simplified quantitative hemolytic assay for classical pathway (CP) hemolytic function in serum that has been shown to correlate with the 50% hemolytic complement (CH50) assay. In the present study, we used this assay to compare CP functions; plasma levels of C3, C4, and C3dg; and ratios of C3dg to C3 in healthy individuals and patients with systemic lupus erythematosus...
Hemolytic assay, bacterial adhesion to hydrocarbons (BATH) assay, drop collapse assay, oil spreading assay, emulsification assay and surface tension measurement were compared for their reliability and ease of use to screen biosurfactant producing bacteria. 105 bacterial strains were screened for their biosurfactant production. Results from screening methods revealed that hemolytic and BATH assa...
Abstract Background: Hereditary red cell enzyme disorders are a group of Non-immune/Spherocytic Hemolytic Anemia, although these disorders are rare and they have not public health problems, the detection of these defects could help to physician in treatment and differential diagnosis. This study evaluated 5 enzymopathies in patients with Hereditary Non –immune/Spherocytic Hemolyti...

Heterocapsa circularisquama (Dinophyceae), a red tide dinoflagellate, is toxic to bivalve molluscs such as the pearl oyster (Pinctada fucata), but no harmful effects of this alga on fish have been observed so far. We found that 7 strains of H. circularisquama showed hemolytic activities toward rabbit erythrocytes in a cell-density dependent manner, but to quite different extents. The strains wh...
