Background: This study was undertaken to investigate whether treatment with vitamin E and N acetyl cystein protects rat sperm by inhibiting reactive oxygen species generation induced by lead (Pb) exposure. Materials and Methods: After an acclimatization period of one week, 20 Male rats were divided into 4 groups of 5 rats each. Animals within different treatment groups were maintained on their ...

Case Report. A 15-year-old boy presented to the Fatih Sultan Mehmet Education and Research Hospital with the complain of bilateral vision blurring associated with severe glare and photophobia. On ophthalmological examination, uncorrected visual acuity was 20/200 in the right eye and 20/100 in the left eye, and there was no improvement with pinhole testing. The slit-lamp examination showed persi...

The objective of present study was to investigate the effects of aqueous garlic extracts, vitamin E and N-acetylcysteine on lead-induced lipid peroxidation, changes in antioxidant defense system and semen quality in the rat testes. Twenty-five male rats were divided into five groups. Animals within different treatment groups were maintained on their respective diets for 35 days as follows: grou...

In this study, a chlorine dioxide solution (UC-1) composed of chlorine dioxide was produced using an electrolytic method and subsequently purified using a membrane. UC-1 was determined to contain 2000 ppm of gaseous chlorine dioxide in water. The efficacy and safety of UC-1 were evaluated. The antimicrobial activity was more than 98.2% reduction when UC-1 concentrations were 5 and 20 ppm for ba...

INTRODUCTION Although inhalation of 80 parts per million (ppm) of hydrogen sulfide (H2S) reduces metabolism in mice, doses higher than 200 ppm of H2S were required to depress metabolism in rats. We therefore hypothesized that higher concentrations of H2S are required to reduce metabolism in larger mammals and humans. To avoid the potential pulmonary toxicity of H2S inhalation at high concentrat...

Bacteria able to mineralize 100 to 200 ppm of pentachlorophenol (PCP) were isolated by selective enrichment from PCP-contaminated soils from three geographic areas of Minnesota. Although differing somewhat in their responses to various biochemical and biophysical tests, all strains were assigned to the genus Flavobacterium. Five representative strains were examined in detail. All strains metabo...

Despite the fact that naphthalene (NA), a volatile, ubiquitous air pollutant, was recently identified as a probable human carcinogen, little is known about nasal cytotoxicity from inhaled NA. To define and compare acute nasal injury from inhalation and systemic NA exposures, male Sprague-Dawley rats were exposed to filtered air; 3.4 or 23.8 ppm NA by inhalation for 4 h; or to 0, 25, 50, 100, or...

In this study, combined effect of two essential oils, Thymol and Carvacrol, with different concentrations in two methods on Gladiolous grandiflorous L. was investigated based on a completely randomized design with 3 replicates and four flower in each replicate. Sansusi variety applied that was red. In short term method, different concentrations of Thymol and Carvacrolin including 25+25, 50+50 a...

OBJECTIVE To explore the safety and efficacy of intravenous (IV) iron sucrose in maintenance peritoneal dialysis (PD). DESIGN Randomized, controlled, parallel-group single-center trial. SETTING Blood Purification Center of Chaoyang, Beijing Capital University of Medical Science, China. METHODS 46 patients on PD were involved in this trial. 26 patients received IV iron sucrose (200 mg iron...

iran is one of the main date (phoenix dactylifera) producing countries in the world. however, little information is available on the pollen viability and favorable storage conditions of iranian male date cultivars. this study was conducted to estimate the best in vitro pollen germination of three male date palm cultivars, `ghanami’, `samsmavi’ and `gheibani’ using various doses of boric acid (0...
