artificial fertilizers and mainly organophosphate herbicide are used by farmers to enhance their crop and control pests. in order to investigate the effects of pretilachlore, fingerlings of caspian roach were exposed to a range of concentrations of toxin close to those of estuary for 96 h. due to movement of these fingerlings in a gradient of salinity from freshwater to brackishwater some physi...

abstract the present study was carried out to investigate the efficacy of two anesthetics, clove oil and ketamine, comparison of hematological parameters, and blood biochemical indices under optimum doses of the two anesthetics in juvenile sterlet acipenser ruthenus (n=276) with an average weight of 64.1 ± 3.4 g. clove oil was used in concentrations of 14, 35, 56, 77, 98 and 119 mg/l, and those...

in the present work, the extraction of zinc from a sphalerite concentrate using sodium nitrate as an oxidant in a sulfuric acid solution was investigated. the effective parameters such as the temperature, sulfuric acid and sodium nitrite concentrations, stirring speed, particle size, and solid/liquid (s/l) ratio were analyzed. the dissolution rate increased with increase in the sulfuric acid an...

Typhoid fever is a systemic life-threatening infection caused by the bacterium Salmonella enterica serotype Typhi occurring more frequently in underdeveloped regions of the world due to overcrowding and poor sanitation. Initiation of appropriate therapy decreases severity and clinical outcome of the disease which requires early and accurate diagnosis. Pathogenesis due to typhoid leads to variou...

The aim of this study was to investigate the comparison between some seminal plasma parameters and age of the bull. Concentrations of various biochemical parameters like fructose, glucose, total proteins, albumin and inorganic ions including Na, K and Cl ions of seminal plasma of breeding Sahiwal bulls of different ageswere assessed. Methods: 40Sahiwal bullsdivided into 4 age groups.Semen (2ml ...

The study was conducted to evaluate the effects of xylazine alone (0.05 mg/kg), lignocaine alone (2.0 mg/kg) and a combination of xylazine and lignocaine (0.05 mg/kg and 2.0 mg/kg, respectively) after lumbar epidural administration in water buffalo calves. Fifteen nondescript, male water buffalo calves of 6-8 months of age and weighing between 55 and 75 kg were randomly placed in 3 groups (A, B...

introduction this study was intended to evaluate the nutritional value, phenolic compounds and digestibility coefficients of barberry leaves. berberis vulgaris is one of the major crops in the province. the province has more than 70 percent and 95 percent of the total area under cultivation of barberry. waste and foliage of barberry harvest traditionally used to feed livestock tannin concentrat...

Introduction: It has been suggested that oxidative stress has a crucial role in the pathophysiology of preeclampsia. In the present study, the effect of tempol, a synthetic antioxidant, on kidney injuries and oxidative stress was investigated in an experimental model of preeclampsia in rats. Methods: Preeclampsia was induced by oral administration of L-NAME to the rats on the day 10 of pregnanc...
