Background and purpose: Presence of heavy metals in water resources is of great concerns due to adverse effects on human health. The aims of this study were to evaluate the efficiency of coagulation process using Polyaluminum Silicate Chloride (PASiC) in removal of hexavalent chromium and Cadmium from aqueous solutions and comparing that to the standards. Materials and methods: Experiments w...
Backgrounds and Objectives : Nitrogen compounds in wastewater are mainly in four types of organic, am- monia, nitrite and nitrate. Total nitrogen concentration in municipal wastewater is usually within 25 to 45 mg/L as nitrogen. The most important problem with nitrogen is its oxygen demand and human health effect.Materials and Methods: Anaerobic Baffled Reactor (ABR) is a system in which baffle...
Introduction: We investigated the role of ATP-sensitive potassium channels and L-type calcium channels in morphine-induced hyperalgesia after nociceptive sensitization. Methods: We used a hotplate apparatus to assess pain behavior in male NMRI mice. Nociceptive sensitization was induced by three days injection of morphine and five days of drug free. On day 9 of the schedule, pain behavior te...
Background: This study was done to determine the effect of root extract of Acalypha indica Linn (akar kucing) in protecting neuron viability of the rat hippocampus on tissue culture in hypoxic condition. Methods: This is an experimental study of in vitro primary cell culture of hippocampus of Sprague Dowley adult rat. The cultures were group into control (C) and exposure to root extract of Acal...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
We attempt to discuss the clinical efficacy and safety of vancomycin in different blood concentrations patients with critically ill infections. collected 50 who received treatment from infectious diseases department our hospital June 2017 2021. Monitored trough concentration selected after reaching steady state. divided into three groups according minimum value i.e. <10 mg/l (n=16), 10 mg/l~15 ...
Frequencies at which mutants resistant to fusidic acid and/or rifampicin arose in vitro were determined in Staphylococcus aureus strains including methicillin-susceptible S. aureus (MSSA), methicillin-resistant S. aureus (MRSA), vancomycin-intermediate resistant S. aureus (VISA) and hetero-VISA. The concentrations of fusidic acid (30 and 15 mg/L) and rifampicin (16 and 1 mg/L) used for selectio...
prangos ferulacea و p. uloptera دو گونه جاشیر از خانواده چتریان می باشند که در طب سنتی به دلیل داشتن خواص ضدنفخ و ضدسرطان استفاده می گردند. در بعضی از رویشگاه ها به دلیل چرای بی رویه دام، نسل آن ها رو به انقراض است. بنابراین، تکثیر گیاه به خصوص از طریق ازدیاد غیرجنسی به روش کشت بافت ضروری به نظر می رسد. در ابتدا، جوانه زنی بذرهای دو گونه جاشیر مورد ارزیابی قرار گرفت. بالاترین درصد جوانه زنی در ...
چکیده prangos ferulacea و p. uloptera دو گونه جاشیر از خانواده چتریان می باشند که در طب سنتی به دلیل داشتن خواص ضدنفخ و ضدسرطان استفاده می گردند. در بعضی از رویشگاه ها به دلیل چرای بی رویه دام، نسل آن ها رو به انقراض است. بنابراین، تکثیر گیاه به خصوص از طریق ازدیاد غیرجنسی به روش کشت بافت ضروری به نظر می رسد. در ابتدا، جوانه زنی بذرهای دو گونه جاشیر مورد ارزیابی قرار گرفت. بالاترین درصد جوانه...
A method is described for estimating plasma and urinary hemoglobin concentrations as low as 3 mg/L. The assay measures at 528 nm the rate of peroxidation of chlorpromazine by hemoglobin and is not affected by ascorbate and bilirubin concentrations up to 500 mumol/L. Results by this method (mean +/- SD: 54.4 +/- 41.6 mg/L; n = 19) correlated well with those by a scanning spectrophotometric metho...
