Vascular endothelial growth factor, p53, and the H-ras oncogene in Egyptian patients with bladder cancer.

Aim: To evaluate the relationship between vascular endothelial growth factor (VEGF), p53, and the H-ras oncogene and different clinicopathological parameters in Egyptian patients with Schistosoma-associated transitional cell carcinoma of the bladder.

Methods: The study included 50 patients with transitional cell carcinoma for whom radical cystectomy and urinary diversions were carried out. VEGF and p53 protein expressions were evaluated with an immunohistochemical staining method, and H-ras oncogene mutations were analyzed with a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique.

Impact of treatment of dyslipidemia on renal function, fat deposits and scarring in patients with persistent nephrotic syndrome.

In this study 43 patients with idiopathic nephrotic syndrome were randomly distributed into 2 age- and sex-matched groups. The first group was given fluvastatin while the second was used as control. The cases in the 2 groups were evaluated clinically, biochemically (creatinine clearance, albumin, 24-hour proteinuria, and lipogram), neurologically, and histopathologically (examination of renal biopsies obtained basally and after 1 year of treatment with fluvastatin).
