Biological Activity of Complement in Vivo

An ln vivo Assay for Biological Activity of Synthesized Recombinant Human Growth Hormone

In-vivo Anticonvulsant and In-vitro Antitubercular Activity of methyl Indole Derivative of some 6-aryl-4, 5-Dihydropyridazin-3(2H)-ones and their Expected Anticonvulsant Mechanisms

Methyl indole derivative of some 6-aryl-4,5-dihydropyridazin-3(2H)-ones (3a-e) were synthesized by Mannich reaction and evaluated as anticonvulsant against MES (50mA, for 2sec), INH (250mg/kg), scPTZ (80mg/kg) and STR (3mg/kg) induced convulsion methods at 50 mg/kg dose level. All compounds 3a-e were also evaluated as antitubercular agent against M. tuberculosis H37Rv by MABA method. All compou...

Characterization of complement activity in serum of the four sturgeon species, Acipenser stellatus, A. baeri, A. nudiventris and Huso huso (Chondrostei: Acipenseridae)

Serum complement is valuable tool in determining the health status of fish. This study was conducted to examine in vitro activity of serum complement as an indicator of innate immunity in four sturgeon species, Acipenser stellatus, A. baeri, A. nudiventris and Huso huso (Chondrostei: Acipenseridae). The Effects of different temperatures, concentrations and volumes of serum on alternative comple...

Biological effect of di (p-methylbenzoyl) diselenide (in vitro) and its acute hepatotoxicity on rats (in vivo)

Selenium plays an important role in biological system due to its incorporation in glutathione peroxidases and thioredoxin reductase as prosthetic group, the pharmacological studies of synthetic organoseleno-compounds revealed these molecules to be used as antioxidants, enzyme inhibitors, neuroprotectors, antitumor, anti-infectious agents, cytokine inducers and immuno-modulators. The present stu...

Preparation and Evaluation anticancer activity of D-glucosamine Nanoparticles on Metastatic cancer Model in vivo

Objective(s): Breast cancer imposes a highest rate of malignancy among the women all around the world. Chitin and its derivatives such as D-glucosamine-carboxymethyl chitin and Di-hydroxy propyl chitin have immune-modulating effects and influence on innate and acquisitive immunity which lead to cell activity enhancement. The aim of this study was investigating the effect ...

P183: Key Function of Complement System in Interactions between Pain and Nociceptors, C5a, and C3a

A part of the immune system that improves (complements) the ability of antibodies and phagocytic cells to clear microorganisms and injured cells from an organism, attacks the pathogen's cell membrane, and encourages inflammation called complement system. It is main part of immune system. Over thirty proteins and protein pieces compose the complement system, including cell membrane receptors, an...
