Contrast-induced nephropathy (CIN) is characterized by acute deterioration of renal function that occurs after parenteral administration of contrast media in the absence of other causes. Although no definite proof has been obtained yet, the risk of diuretics or angiotensin-converting enzyme inhibitors (ACEI) to exacerbate CIN has been reported because of their effects on renal perfusion. This study was conducted to assess the protective effect of hydration alone in the prevention of CIN after percutaneous coronary intervention (PCI) in patients on diuretics or ACEI. This randomized clinical trial was conducted at the Chamran Hospital, Isfahan University of Medical Sciences, Iran, during the years 2006-2007. The study patients were divided into four groups, each group containing 60 patients. Patients in groups A and B were on regular treatment with ACEI (captopril) and patients in groups C and D were on regular diuretic (furosemide) therapy. About 36 h before PCI, captopril in group A and furosemide in group C were discontinued. The serum creatinine (Cr) levels were measured at the time of performing PCI and 24 h and 48 h after PCI in all patients. All patients received 1 mL/kg/h normal saline (0.9%) 12 h before and 24 h after PCI. The occurrence of CIN after PCI was diagnosed based on the following formula: Cr level after PCI - Cr level before PCI. If this value was greater than 0.5 mg/dL, it was coded as one and if the value was less than 0.5 mg/dL, it was coded as zero. The mean difference was analyzed and compared among the four groups by the ANOVA test. Three patients (5%) in group A, two patients (3.3%) in group B, two patients (3.3%) in group C and one patient (1.6%) in group D had a >0.5 mg/dL difference in serum Cr. The difference seen between these groups was not statistically significant (P > 0.05). This study shows that although furosemide and captopril can exacerbate CIN by impairment of renal perfusion, this can be prevented by hydration and discontinuation of furosemide and captopril may not be required.

In recent years, the development of efficient green chemistry methods for synthesis of metal nanoparticles has become a major focus of researchers. They have investigated in order to find an eco-friendly technique for production of well-characterized nanoparticles. One of the most considered methods is production of metal nanoparticles using organisms. Among these organisms plants seem to be the best candidates and they are suitable for large-scale biosynthesis of nanoparticles. Nanoparticles produced by plants are more stable and the rate of synthesis is faster than in the case of microorganisms. Moreover, the nanoparticles are more various in shape and size in comparison with those produced by other organisms. The advantages of using plant and plant-derived materials for biosynthesis of metal nanoparticles have interested researchers to investigate mechanisms of metal ions uptake and bioreduction by plants, and to understand the possible mechanism of metal nanoparticle formation in plants. In this review, most of the plants used in metal nanoparticle synthesis are shown. © 2011 The Royal Society of Chemistry. Source

Context: In the meadow of medical sciences substituting a diseased organ with a healthy one from another individual, dead or alive, to allow a human to stay alive could be consider as the most string event. In this article we review the history of transplantation, mechanisms of rejection, nephro-neurotoxicity of tacrolimus and cyclosporin in organ transplantations. Evidence Acquisitions: Directory of Open Access Journals (DOAJ), Google Scholar, Pubmed (NLM), LISTA (EBSCO) and Web of Science have been searched. Results: The first reference to the concept of organ transplantation and replacement for therapeutic purposes appears to be to Hua-To (136 to 208 A.D), who replaced diseased organs with healthy ones in patients under analgesia induced with a mixture of Indian hemp. In 1936, the first human renal transplant performed by Voronoy in Russia. The first liver transplant in humans was performed on March 1, 1963 by Starzl in Denver, USA. Medawar was the first to assert that rejection was an immunological response, with the inflammatory reaction due to lymphocyte infiltration. Consequently, rational immunosuppressive therapies could inhibit deleterious T-cell responses in an antigen specific manner. Conclusions: Searching related to the history of organ transplantation from mythic to modern times suggests that, to prevent graft rejection, minimize nephro and neuro toxicity monitoring of immunosupressive concentrations could provide an invaluable and essential aid in adjusting dosage to ensure adequate immunosuppression. © 2012, Society of Diabetic Nephropathy Prevention.

The treatment of brain disorders is one of the greatest challenges in drug delivery because of a variety of main barriers in effective drug transport and maintaining therapeutic concentrations in the brain for a prolonged period. The objective of this study was delivery of valproic acid (VPA) to the brain by intranasal route. For this purpose, nanostructured lipid carriers (NLCs) were prepared by solvent diffusion method followed by ultrasonication and characterized for size, zeta potential, drug-loading percentage, and release. Six groups of rats each containing six animals received drug-loaded NLCs intraperitoneally (IP) or intranasally. Brain responses were then examined by using maximal electroshock (MES). The hind limb tonic extension:flexion inhibition ratio was measured at 15-, 30-, 60-, 90-, and 120-minute intervals. The drug concentration was also measured in plasma and brain at the most protective point using gas chromatography method. The particle size of NLCs was 154 ± 16 nm with drug-loading percentage of 47% ± 0.8% and drug release of 75% ± 1.9% after 21 days. In vivo results showed that there was a significant difference between protective effects of NLCs of VPA and control group 15, 30, 60, and 90 minutes after treatment via intranasal route (P < 0.05). Similar protective effect was observed in rats treated with NLCs of VPA in intranasal route and positive control in IP route (P > 0.05). Results of drug determination in brain and plasma showed that brain:plasma concentration ratio was much higher after intranasal administration of NLCs of VPA than the positive control group (IP route). In conclusion, intranasal administration of NLCs of VPA provided a better protection against MES seizure. Source

Antiphospholipid syndrome (APS) is being increasingly recognized as an important cause of kidney injury due to thrombosis at any location within the renal vasculature. The term antiphospholipid syndrome nephropathy (APSN) refers to the kidney damage caused by vascular lesions in the glomeruli, arterioles and/ or interlobular arteries in patients with antiphospholipid antibodies. APSN manifests with hypertension, acute and/or chronic kidney failure, and often a lowgrade proteinuria. © 2014 by Journal of Nephropathology (JNP). Source
