Cisplatin is widely used in anticancer therapy, but a substantial percentage of patients who receive the therapeutic dose of cisplatin develop nephrotoxicity. Hepatotoxicity may also develop after a single dose or low repeated doses of cisplatin. Ulva fasciata is an edible seaweed, commonly known as sea lettuces have also been shown various biological activities. In this study, ethanol extract and its solvent fractions (n-hexane and chloroform) of U. fasciata were given (orally) to different groups of rats for 10 days. Injury to the kidney was induced by administrating cisplatin, intraperitoneally (i.p.) to rats at a dose of 7 mg/kg body weight (b.w.) dissolved in 1 mL saline, at 5th day of the experiment. At 10th day rats were sacrificed and kidney parameters (creatinine, urea, and blood urea nitrogen (BUN)) and electrolyte balance (Ca++, Mg++, K+, and Na+) in serum were determined, while oxidative stress markers glutathione (GSH), catalase (CAT) and malondialdehyde (MDA), and inflammatory cytokines, tumor necrosis factor (TNF alpha), and interleukin (IL-6) were determined in kidney tissues. Histological examination of the kidney was also performed to examine the changes in kidney tissues. Cisplatin caused adverse effects on blood parameters, antioxidants, and inflammatory markers with severe renal tubular injury in kidney tissues. Ethanol extract of U. fasciata and its fractions effectively improved these disorders and diminished the renal dysfunction. However, ethanol extract was found more effective in attenuating the adverse effect of cisplatin than its fractions. n-Hexane-soluble fraction that was subjected to GC-FID and GC-MS analysis revealed the presence of several compounds and some of them are new from this source. It could be concluded that the U. fasciata possesses nephroprotective effect and can attenuate cisplatin-induced renal dysfunction. Since U. fasciata is an edible seaweed, it may be used as a diet supplement.

Objectives The aim of this study was to identify the genotypic analysis and allele frequencies of the -173 G/C polymorphism in the macrophage migration inhibitory factor (MIF) gene in children diagnosed with familial Mediterranean fever (FMF). Methods The study included 98 children who were diagnosed with FMF according to the Tel Hashomer criteria and one hundred and 57 healthy children as the control group. Genotyping was done for a polymorphism in a promoter region of the MIF gene (G/C at position -173). Results The relationship of FMF prevalence and -173 G/C genotype of the MIF gene was statistically significant. Individuals with the CC genotype seem to be predisposed to FMF. Conclusion The C/C polymorphism at position -173 of the MIF gene could be associated with excessive inflammation and immune response and can lead to susceptibility to FMF
