Surfactants in soap preparations serve as active ingredients that can reduce surface tension between oil and water. So far, surfactant for widely used is either chemical or synthetic surfactants. Therefore, order to protect the environmental safety need find surfactants from natural materials. One of be made a lignin-based surfactant, namely sodium lignosulfonate.The lignosulfonate rice straw w...

citicoline is a natural substance with neuroprotective and repairing effects. it can also increase the phosphor metabolites in cerebral cortex. regarding the various effects of citicoline on central nervous system, this research aims at studying the effects of citicoline on the thiopental sodium anesthesia. six dogs were anesthetized by intravenous injection of 20 mg ∕ kg of 2.5% thiopental sod...

BACKGROUND The objective was to describe a case of occupational asthma in a fisherman linked to the inhalation of metabisulphites, then to discuss the history and actions for prevention. MATERIAL AND METHODS We report the case of a fisherman fishing for Dublin bay prawn (Nephrops), who suffered from asthma after being exposed to metabisulphites. This case is compared with other cases in the o...

The sulfites are widely used as anti-browning agents and preservatives in food, cosmetics and medicine. The use and amount of sulfites in products have recently been regulated by the Food and Drug Admini...

Inhalation of sodium metabisulphite is thought to induce bronchoconstriction by release of sulphur dioxide. We sought to establish the reproducibility of the airway response to inhaled sodium metabisulphite given in increasing doubling concentrations (0.3 to 160 mg/ml) to 13 asthmatic and five atopic non-asthmatic subjects and the contribution of cholinergic mechanisms to this response. In 15 o...

The ubiquity of sulfur dioxide as an air pollutant combined with reports of effects of the gas and its blood metabolite on DNA and chromosomes, prompted a study of possible mutagen action on mammalian oocytes. Utilizing in vitro and in vivo systems, mouse, ewe, and cow oocytes were examined for cytologic evidence of structural or numerical damage in meiosis. Fragmentation with rearrangement see...

Desarrollamos un estudio observacional, prospectivo multicéntrico pacientes consecutivos del registro Grupo Español In...

BACKGROUND Sodium metabisulphite (MBS) is known to induce bronchoconstriction in asthmatic patients. The effects of MBS on guinea pig airway smooth muscle and on neurally mediated contraction in vitro have been examined. METHODS Tracheal and bronchial airway segments were placed in oxygenated buffer solution and electrical field stimulation was performed in the presence of indomethacin (10(-5...

objective studies on the effect of various antiepileptic drugs on serum lipids show contradictory results. we aimed to find the effect of phenobarbital and sodium valproate monotherapy on serum lipid profile and liver function tests in epileptic children. materials & methods this cohort study was conducted in amirkola children hospital. one hundred and ten children with epilepsy were included i...

Several stimuli which aVect the osmolarity of airway surface liquid may induce bronchoconstriction in asthmatic subjects, indicating that in these patients the control of the bronchial calibre is aVected by the physicochemical characteristics of the airways lining fluid. In the last few years this hypothesis has been confirmed using a number of drugs which are known to aVect cellular ion transp...
