OBJECTIVES The Ferula genus (Umbelliferae) is a rich source of gum-resin and is much utilized in folklore medicine. This study is designed to examine antioxidant and antihaemolytic activities of Ferula foetida regel flower, stem and leaf extracts. MATERIALS AND METHODS 1,1-Diphenyl-2-picryl hydrazyl radical (DPPH), nitric oxide and H2O2 scavenging activities, Fe2+ chelating ability, reducing ...

RATIONALE Pigmented villonodular synovitis (PVNS) is an idiopathic, proliferative disorder lesion of synovial tissue, which is regarded as a benign disease, but has a local invasion. Up to now, these are no consensus about the etiology and pathogenesis of PVNS. Because of the lack of typical clinical features, misdiagnosis and delayed diagnosis are not uncommon, magnetic resonance imaging (MRI)...

A study has been made of the kinetics of lysis induced by various hemolytic agents. The course of bemolysis was followed by mixing lysin with washed human erythrocytes, removing samples from the mixture, and estimating colorimetrically the hemoglobin in the supernatant fluid of the centrifuged samples. Most of the curves (but not all of them, e.g. tyrocidine) obtained by plotting degree of hemo...

Cydonia oblonga Miller (C. oblonga) is known for its beneficial properties health since ancient times. C. has also been shown to possess antihemolytic, antidiabetic, and antilipoperoxidation, as well lipid-lowering properties. Modern research that antitumor effects. However, studies have not reported whether main compounds inhibit renal cell carcinoma (RCC) development progression. We found the...

Evidence has been reported to indicate that red blood cells (RBCs) may potentiate platelet adherence and platelet aggregation (PAG) in different flow systems in vitro as well as hemostatic platelet plug formation in response to vascular injury. In this study, we demonstrate that RBCs enhance PAG induced by well-defined, low-intensity, uniform, laminar shear stress. Potentiation by RBCs of shear...
