Effects of Hypericum perforatum (St. John’s wort) extract on renal function after unilateral ureteral obstruction in rat
Obstructive nephropathy induced by urine reflux due to uroliths, prostatic hypertrophy and other disorders will result in renal interstitial fibrosis and inflammation. Because ofHypericum perforatums (HP) anti-oxidant and anti-inflammatory properties, the clinical usage of this drug in renal function has been studied. We divided 30 Sprague-Dawley rats randomly into 5 groups: sham group (Sham), untreated unilateral...

The antitumor effects of Araloside A extracted from the root bark of Aralia elata on human kidney cancer cell lines
Aralia elata was used as therapeutic medicine in oriental courtiers a few hundreds years ago. As one important constituent extracted from Aralia elata, Araloside A has been shown to treat gastric ulcers, hepatitis, and arrhythmias. It is not yet known, however, whether Araloside A may induce cell apoptosis in renal cell carcinoma. We therefore examined the antitumor effects of Araloside A on human kidney...

Cardiovascular drug adverse reactions in hospitalized patients in cardiac care unit
The aim of the present survey was to evaluate different aspects of cardiovascular drug adverse reactions in a cardiac care unit (CCU). All patients admitted to CCU during a 16 months period were recruited into this study. Detection of adverse drug reactions(ADRs) was based on daily chart review and face to face interview with patients. Causality assessment was performed by the World Health...

Amelioration of chronic cyclosporine A-induced nephrotoxicity by telmisartan in rats
Nephrotoxicity is a major problem of Cyclosporine A (CsA) treatment, despite its beneficial role in organ transplantation and in a variety of immunologic disorders. This study was undertaken to investigate the potential renoprotective role of telmisartan in amelioration of chronic CsA induced nephrotoxicity. The rats were randomized into 4 equal groups. Group 1 received normal saline (control), group 2 received...

Anti-oxidative effects of flavonoids enriched Corni fructus extract and the mechanism
We tested to determine if Corni fructus extract has antioxidant activities and explored its potential mechanism in terms of iNOS and COX-II involvement. Anti-oxidative actions were explored by measuring free radical (NO, DPPH) scavenging activity, and TBARS levels. The mechanism of anti-oxidative action of Corni fructus extract was determined by performing Western blot analysis for iNOS and COX-II expression in...

The effects of gender and exercise on malondialdehyde, nitric oxide and total glutathione levels in rat liver
This study examined the effects of gender, acute exhaustive exercise and endurance training on the levels of malondialdehyde (MDA), nitric oxide (NOx) and total glutathione (GSH) in rat liver. The study was carried out with 12-week-old male and female Wistar rats. Rats were randomly divided into four subgroups: untrained-control, trained-control, untrained-exhausted, and trained-exhausted. Endurance training consisted...

Serum leptin level in healthy sedentary young men after a short-term exercise
The effects of an 8 weeks endurance training program on body characteristics and serum leptin concentration were investigated in sedentary young men. The body mass index, body weight and body fat percentage of healthy, sedentary university students were recorded before and after the exercise program and their relationship to serum leptin level was attained. Body fat percentage after training considerably decreased...

Pharmacological studies of some pyrimidino derivatives
Pyrimidine derivatives, in general, have received significant interest due to their purported biological activities the anti-inflammatory, analgesic, anti-parkinsonism, and anti-microbial activities for five 2[(N-methyl indolyl)-methyl] pyrimidino derivatives 1-5 is reported. Pharmacological screenings showed that these compounds have good anti-inflammatory, analgesic, anti-parkinsonism, and anti-microbial activities...

A study on serum leptin, lipoproteins and glucose levels of judoists and cyclists of Turkey
Fat metabolism is important for judo in weight loss and recovery and for cycling in the energy production and recovery during workouts and competitions. Leptin controls the size of fat stores by inhibiting appetite. The purpose of this study was to compare serum leptin, lipoproteins and glucose levels between male national judoists and cyclists. The subjects of this study consist of totally 61 athletes, including 24...

Bacteriology of burns and antibiogram in an Iranian burn care center
Burn patients face an obviously high risk for infections due to the immunocompromising effects of their injury. This study aimed to detect and identify bacteria isolated from patients and hospital environment in the burn unit and determine their antibiogram pattern in response to commonly used antimicrobial agents; in order to give recommendations for management of bacterial infections and drug-resistance. Materials of...

Association of E23K polymorphism of Kir6.2 gene with coronary artery disease
The ATP-sensitive potassium (KATP) channels are generally cardioprotective under conditions of metabolic impairment, consisting of pore-forming Kir 6.X (Kir 6.1 and Kir 6.2) subunits in combination with regulatory sulfonylurea receptor (SUR1, SUR2A and SUR2B) subunits. E23K is a missense single nucleotide polymorphism (SNP) located in the cytosolic proximal N-terminal tail of the Kir6.2 subunit. We investigated the...
