this experiment was conducted to investigate the effects of different levels of oxidized fat (yellow grease) and copper sulfate on performance, carcass traits, blood metabolites and immune cells of broilers. this study was carried out as a 3 × 2 factorial experiment with 3 levels of oxidized fat (0, 2 and 4%) and 2 levels of copper sulfate (0 and 300 mg/kg) in 6 treatments, 3 replicates and 12 ...

Background: Entry of untreated wastewater of wool scouring factories has been associated with many environmental hazards because of high rate of pollution. Presently effective treatment methods and reducing the costs of operation and maintenance from treatment units have always been under the attention of this industry owners. The aim of this survey is to present a suitable method for the treat...

The effects of streptomycin sulfate, carbendazim, penicillin and nystatin on the inhibition fungi bacteria in blueberry explants were studied. results showed that addition sulfate or with different concentrations medium had a certain inhibitory killing effect explant contamination, while carbendazim contamination. When concentration reached 60units / mL, highest survival rate was 44.0%, bacteri...

Mixed-microbial assemblages enriched from a septic tank, coastal sediment samples, the digester sludge of a brewery wastewater treatment plant and acidic sulfate soil samples were compared on the basis of growth rate, waste and sulfate reduction rate under sulfate reducing conditions at 30 degrees C. The specific growth rate of various cultures was in the range 0.0013-0.0022 hr(-1). Estimates o...

Sulfide oxidation is a common phenomenon associated with many mined ore bodies and extracted or processed waste. Where the products of these chemical reactions can enter a water body the result is often a reduction in water quality through the increase of acidity, metals and dissolved salts. Due to an attributed lower environmental impact the release of sulfate has received little attention in ...

Maintaining quality and longevity of cut flowers is one of the critical issues in the floriculture industry, especially in cut flowers; and one of the most important problems in chrysanthemum, as one of the most popular cut flowers. Therefore, an experiment was conducted based on completely randomized design as pulse treatment with the three factors: tea extracts with 4 levels (5, 10, 20, and 4...

The objective of this study was to evaluate effects of zinc oxide nanoparticles (nano-ZnOs) as a substitute for colistin sulfate (CS) and/or zinc oxide (ZnO) on growth performance, serum enzymes, zinc deposition, intestinal morphology and epithelial barrier in weaned piglets. A total of 216 crossbred Duroc×(Landrace×Yorkshire) piglets weaned at 23 days were randomly assigned into 3 groups, whic...

Chondroitin sulfate from bovine tracheal cartilage, with the basic structure (4-O-sulfo-D-GalpNAc beta-1-->4-D-GlcpA)n, was chemically modified by O-sulfonation. Depending on the reaction conditions, the products showed a different degree of O-sulfonation. A fully O-sulfonated chondroitin sulfate, having no free hydroxyl groups, and a sulfo ester group:disaccharide unit ratio of 4.0 was prepare...

The present study is a designed protocol for investigation of the analgesic effect of oral and intraperitoneal (i.p.) administration of alcoholic Datura stramonium (DS) seed extract as a rich source of alkaloid substances. Male NMRI rats were divided into control and treatment groups. The treatment rats received different doses of the DS seed extract, which was prepared from alcoholic smashed s...

OBJECTIVES This single-dose study compares three dehydroepiandrosterone delivery methods (oral crystalline steroid, micronized steroid, and vaginal administration) to ascertain whether physiologic levels of circulating dehydroepiandrosterone and dehydroepiandrosterone sulfate can be obtained while increases in testosterone are minimized. STUDY DESIGN Two randomized, double-blind, placebo-cont...
