AIMS The most effective regimen for the prevention of contrast-induced nephropathy (CIN) remains uncertain. Our purpose was to compare two regimens of sodium bicarbonate with 24 h sodium chloride 0.9% infusion in the prevention of CIN. METHODS AND RESULTS We performed a prospective, randomized trial between March 2005 and December 2009, including 258 consecutive patients with renal insufficie...

Sir: A new indolocarbazole antibiotic SF-2370 has been found in the culture broth of Actinomadura sp. SF-2370 which was isolated from a soil sample collected at Shimizu, Shizuoka Prefecture, Japan. The antibiotic is weakly active against some bacteria and fungi. In this communication, the isolation, characterization, and structural elucidation by the spectral studies are reported. Actinomadura ...

It has been reported that latex and extracts of different species of Ficus are cytotoxic to some human cancerous cell lines. In this study, cytotoxicity of fruit and leaf extracts as well as the latex of Ficus carica L. on HeLa cell line were evaluated. Ethanolic extracts of leaves and fruits were prepared through percolation and ethyl acetate and dichloromethane extracts were prepared by reflu...

The rate of bactericidal activity and inactivation of metronidazole was studied in time-kill curves with Haemophilus vaginalis (Corynebacterium vaginale). The minimum inhibitory concentrations of metronidazole for the eight strains tested ranged from 4 to 16 micrograms/ml. At a concentration of 20 micrograms/ml, metronidazole demonstrated a slow cidal effect against exponential-phase organisms,...

Three studies were conducted to examine the role of progesterone in stimulating sexual receptivity in estrogen-treated, ovariectomized gilts. Progesterone was administered either before, simultaneously with, or 48 h after estrogen. In each study, gilts were treated with either a suboptimal or an optimal dosage of estradiol benzoate (EB). Progesterone treatment (600 micrograms/kg BW-1 X injectio...

Introduction: The Serum/Glucose deprivation -induced cell death in cultured PC12 cells represents a useful in vitro model for the study of brain ischemia and neurodegenerative disorders. Nigella sativa L. has been known as a source of antioxidants. To elucidate the neuroprotective actions of N. sativa extract in vitro, we studied the effect of N. sativa extract on cultured PC12 cells under s...

This study evaluated the antifungal activity of Persea americana extract on Candida albicans biofilm and its cytotoxicity in macrophage culture (RAW 264.7). To determine the minimum inhibitory concentration (MIC), microdilution in broth (CLSI M27-S4 protocol) was performed. Thereafter, the concentrations of 12.5, 25, 50, 100, and 200 mg/mL (n = 10) with 5 min exposure were analyzed on mature bi...

Sperm selection techniques have became an important tool to improve sub fertile ejaculates. The main aim of this study was to assess the dynamics of motile sperm subpopulations of ejaculates from subfertile stallions subjected to density gradient centrifugation (DGC) involving a double layer colloid [DGC2], before and after storage for 24 and 48 hours. Ejaculates from eight stallions with ferti...

Introduction. Hepatorenal syndrome type I (HRS I) may be a consequence of circulatory dysfunction in cirrhotic patients with portal hypertension. This uncontrolled interventional pilot study examines the hemodynamic and renal effects of large volume plasma expansion in HRS I. Material and methods. 14 cirrhotic patients (8 m, 6 f, age 60 (58-65) years) with HRS I received large volume plasma exp...
