Therapeutic use of biological response modulators in combination with chemotherapeutic drugs may propose a more efficient way for cancer therapy with fewer side effects. However, the related mechanism has not been well understood. Γ-interferon is a modulator of biological responses that inhibits the growth of malignant cells and mediates their differentiation. In this investigation, T cell lymp...

Integrins are the major receptors within the extracellular matrix (ECM) that mediate several functions connected with cell life and metabolism, such as cell adhesion, migration, cytoskeletal organization, proliferation, survival, and differentiation. A vascular endothelial growth factor (VEGF) is one of the most important angiogenic factors. It has been suggested that the expression of this gen...

there are few reports concerning interferon induced myocardial dysfunction. a known case of multiple myeloma who was receiving interferon alpha (ifa) for 14 months was brought to the emergency room in frank: pulmonary edema. after treatment of heart failure and discontinuation of interferon alpha, he remained asymptomatic thereafter. another case of chronic active hepatitis on ifa complained of...

background: patients with bleeding disorders are frequently infected with hepatitis c virus (hcv). there are few reports on the effect of standard interferon in these patients and no published report on pegylated interferon. the aim of this study was to compare pegylated interferon alpha-2a and standard interferon alpha with ribavirin in patients with bleeding disorders and chronic hcv infectio...

Forty-two extracts of folk medicinal plant organs from Pakistan were tested in competition binding assays for their interaction with the specific ligand recognition sites on the human alpha2-adrenoceptor subtypes alpha2A, alpha2B and alpha2C Strong binding of the extracts (40 mg/ml) from Acacia nilotica (L.) Delile leaves (88-98% displacement of radiolabel) and Peganum harmala seeds (89-96% dis...
