this article describes a simple and fast high-performance liquid chromatography method for the determination of methotrexate (mtx) in plasma. samples were collocted from children receiving high-dose mtx at shafa hospital (ahvaz university of medical sciences, ahvaz, iran) at various times after the end of eachinfusion. plasma was deproteinized with trichloroacetic acid and the supernatant was i...

a rapid, simple and sensitive high-performance liquid chromatography method was developed for determination of ciprofloxacin in plasma by means of ultraviolet detection. ofloxacin was used as an internal standard and separation carried on a novapak c18 column using a mobile phase of 0.01 m phosphate buffer (ph =2.6): methanol (82: 18 v/v). extraction of drug was performed from plasma by liquid-...

a 54 year old man with history of cardiomyopathy and chronic fibrillation first presented with bloody diarrhea. then during the assessment of his abnormal lab. data revealed cast nephropathy in renal biopsy, gamma peak in protein electrophoresis and fine lytic lesions in skull graphy. his bone marrow aspiration showed multiple myeloma and blood smear revealed plasma cell leukemia. our patient w...

conclusions hemodialysis exacerbates oxidative stress and conformational changes of hb in patients with diabetes on hemodialysis. the frap value can be used as a positive determinant, while pco and hb derivatives can be used as negative determinants of oxidative stress in patients with diabetes. background diabetes is associated with an increased generation of reactive oxygen species (ros), whi...

dietary antioxidants including phenolic compounds are believed to be effective nutrients in the prevention of oxidative stress related disease. pomegranate has been used for centuries in ancient cultures for its medicinal purpose and is widely acknowledged for antioxidant properties. the present study was designed to assess the effect of pomegranate fresh fruit consumption on the plasma antioxi...

background: in this study we have prepared the iga solution from normal human plasma using plasma fractionation and ion exchange chromatography. materials and methods: using fractionation of plasma with cold ethanol (starting with 8% ethanol), fraction iii was prepared as a suitable source for iga preparation. then it was treated with caprylic acid for separation of impurities. for enrichment o...

background ghrelin and obestatin are orexigenic and anorexigenic peptides, respectively. it appears that an accurate balance between theses peptides is important for regulating energy homeostasis and body weight. objectives the aim of this study was to identify the possible mechanisms by which circuit resistance training influences energy homeostasis and weight control. patients and methods twe...

background: fatalities from acetaminophen poisoning are common, but they are preventable by timely treatment with n-acetyl cysteine (nac). in many medical centers, nac is prescribed in keeping with the ingested dose of the drug as revealed through medical history. it seems to significantly differ from the real indications of nac administration based on plasma level of acetaminophen. overtreatme...

patients with limbic encephalitis usually present with new onset mesial temporal lobe seizures, progressive memory disturbance, and a variety of other behavioral, emotional, and cognitive changes. autoimmune inflammation of the limbic gray matter structures of the human brain has recently been identified as major cause of mesial temporal lobe epilepsy with interictal temporal epileptiform activ...
