This study aimed at evaluating the effect of acetylsalicylic acid (ASA) (150 and 300 mg/kg b.w.) on urinary trichloroethanol and trichloroacetic acid excretion and the liver cytochrome P-450-dependent monooxygenase system (MFO) in rats treated with trichloroethylene (TRI) alone or with xylene (XYL) at a concentration of 4.5 mmol/m air. The study has shown that xylene equally decreased trichloro...

BACKGROUND There is increasing evidence to show that leukotrienes are important mediators in asthma. Leukotriene receptor antagonists protect against antigen and exercise challenges in patients with chronic asthma. A study was undertaken to investigate the activity of the leukotriene receptor antagonist pranlukast (SB 205312, ONO-1078) in blocking bronchoconstriction induced by leukotriene D4 (...

BACKGROUND Accidents are the second reason for mortality and morbidity in Iran. Among them, brain injuries are the most important damage. Clarification of the effects of brain injuries on different body systems will help physicians to prioritize their treatment strategies. In this study, the effect of pure brain trauma on the cardiovascular system and lungs 24 hours post trauma was assessed. ...

The effect of various substances on the composition and quality wine has been studied. Only imazalil residue was 0.35 µg/dm3, in course use activated coal a dose 300 mg/dm3 no other pesticides were found. pesticide totally over during next doses (450 & 600 mg/dm3) coal. So, 450 is sufficient to remove out examples. more significant bentonite mg/dm3. In this case, most affected one imazalil. İnc...

ABSTRACT The problem addressed is the contamination of Yarinacocha Lagoon water by heavy metals and poor use agricultural residues. It was manufactured activated carbon from cocoa (Theobroma cacao L.) pod husks determined its adsorbent effect in removing polluting waters Lagoon. response surface methodology applied with factorial designs 33 32, three replicates to optimize obtaining measure eff...

Abstract Aluminum-based alloys have wide applicability in the construction of aircraft, vehicles, and ships. Some their components, during operation, such as radiators rotors cooling pumps propellers fishing pleasure boats are affected by abrasive, chemical cavitational corrosive action water. At certain hydrodynamic flow regimes, most dangerous becomes corrosion through cavitation. Operation r...

An extensive series of ligand complexes of ferric cytochrome P-450-CAM has been examined by UV-visible absorption, magnetic circular dichroism, and electron paramagnetic resonance spectroscopy in an attempt to identify the ligand trans to cysteinate in the six-coordinate resting state of the enzyme. Thus, the ligands used have been chosen to serve as models for coordination by potential endogen...

Bacillus sp. can biosynthesize fibrinolytic enzymes. Culture conditions and nutrient sources are important factors affecting microbial growth production of the Fibrinolytic enzyme. Therefore, we investigated culture strain ES4, such as temperature, pH, C source (glucose, sucrose, glycerol, maltose), N (yeast extract, meat content, peptone, tryptone), metal ions (Ca 2+ , Mg Mn Zn K + Fe Cu ), ti...
