Protective effect of apocynin, a NADPH-oxidase inhibitor, against contrast-induced nephropathy in the diabetic rats: a comparison with n-acetylcysteine.

The aim of this study was to investigate the effects of apocynin, a NADPH (nicotinamide adenine dinucleotide phosphate)-oxidase inhibitor, in diabetic rats with nephropathy induced by contrast medium (CIN). Diabetes was induced in male Wistar rats by a single dose of streptozotocin (60 mg/kg i.v.

Pharmacological and clinical overview of cloperastine in treatment of cough.

Cough constitutes an impressive expression of the normal defense mechanisms of the respiratory system. Productive cough associated with catarrh is an important protective system for the lung because it favors the upward movement of secretions and foreign bodies to the larynx and mouth. Cough may also appear without bronchial secretions, as dry cough, which may be persistent when inflammatory disease is chronic or when, in the early stages of respiratory disease, bronchial secretions are not yet fluid.

Design and evaluation of a semantic approach for the homogeneous identification of events in eight patient databases: a contribution to the European EU-ADR project.

The overall objective of the EU-ADR project is the design, development, and validation of a computerised system that exploits data from electronic health records and biomedical databases for the early detection of adverse drug reactions. Eight different databases, containing health records of more than 30 million European citizens, are involved in the project. Unique queries cannot be performed across different databases because of their heterogeneity: Medical record and Claims databases, four different terminologies for coding diagnoses, and two languages for the information described in free text.

Hemorrhagic cystitis induced by an herbal mixture.

A healthy 33-year-old woman consumed a slimming product containing a mixture of herbal remedies without seeking medical advice. Two months later, the patient had hemorrhagic cystitis and discontinued the herbal product. Symptoms spontaneously remitted in a few days.

Data mining on electronic health record databases for signal detection in pharmacovigilance: which events to monitor?

Purpose: Data mining on electronic health records (EHRs) has emerged as a promising complementary method for post-marketing drug safety surveillance. The EU-ADR project, funded by the European Commission, is developing techniques that allow mining of EHRs for adverse drug events across different countries in Europe. Since mining on all possible events was considered to unduly increase the number of spurious signals, we wanted to create a ranked list of high-priority events.

Drug safety information through the internet: the experience of an Italian website.

Background: The Internet may play a crucial role in the prompt provision of updated drug safety information. Nevertheless, limited knowledge of the English language among healthcare professionals or suboptimal search skills constitute barriers to widespread and appropriate use of the Internet for this purpose in Italy. In order to provide accurate information on drug safety and to promote the reporting of adverse drug reactions, in 1999 the clinical section of the Italian Society of Pharmacology created the website www.

Gynecomastia possibly induced by rosuvastatin.

Gynecomastia is characterized by benign progressive enlargement of the male breast. A pharmacologic origin is identified in 10-20% of cases. Several case reports have associated this condition to the use of statins.

Recombinant human erythropoietin stimulates angiogenesis and healing of ischemic skin wounds.

Wound healing in ischemic tissues such as flap margins due to inadequate blood supply is still a source of considerable morbidity in surgical practice. Adequate tissue perfusion is particularly important in wound healing. We investigated the effects of recombinant human erythropoietin (rHuEPO) on wound healing in an ischemic skin wound model.

Enhancement of expression of vascular endothelial growth factor after adeno-associated virus gene transfer is associated with improvement of brain ischemia injury in the gerbil.

Angiogenesis induced by growth factors may represent a rational therapy for patients with stroke. Vascular endothelial growth factor (VEGF) plays a pivotal role in angiogenesis and VEGF expression is enhanced in the post-ischemic brain. VEGF induced by brain hypoxia can lead to the growth of new vessels and may represent a natural protective mechanism improving survival after stroke.

Oral administration of a soy extract improves endothelial dysfunction in ovariectomized rats.

Effects of oral administration for 4 weeks of a soy fraction with mainly isoflavones (Glycine max, Leguminosae) (SOYPH; 5 mg/kg) on vascular dysfunction induced by bilateral ovariectomy (OVX) in rats were studied. We evaluated vascular reactivity of aortic rings after acetylcholine (ACh 10 nM-10 microM), sodium nitroprussiate (SN 15 - 30 nM) and NG-L-arginine (L-NMA; 10 - 100 microM). Uterine weight and nitric oxide synthase (NOS) activity were also investigated.
