cotton bollworm, helicoverpa armigera (hübner) is one of the most destructive insect pests on many crops in the world that has been found to develop resistance against conventional insecticides. using insecticides with different modes of action may result in appropriate control of the pest and delay insecticide resistance development. in this study, lethal and sublethal effects of emamectin ben...

The in vitro activity of ofloxacin (DL8280), a new pyridone carboxylic acid, against Chlamydia trachomatis serotype E was assessed by growth of chlamydia in cycloheximide-treated McCoy cells. Chlamydia-infected monolayers were exposed to the drug for 48 and 96 h and for 48 h followed by 48 h of further incubation after withdrawal of ofloxacin. Inclusions were visualized by indirect immunofluore...

Preliminary studies have been conducted on various parameters in order to assess the possible and relative toxicities of a number of metallic salts. Upon oral administration in lethal-dose experiments, two soluble Pt4+ salts were more toxic than the other salts tested. Following intraperiotneal injection in lethal-dose experiments, PbCl2 was less toxic than several of the soluble or partially s...

objective(s): this study aimed to determine the possible toxicity of cuo nanoparticles (nps) on oncorhynchus mykiss by evaluating hematological parameters.materials and methods: fish were sampled and treated in 4 aquariums containing the concentration ranges of 1, 5, 20 and 100 ppm of cuo nps. there was one control group (no cuo nps) and three replicates. the physicochemical properties of water...

Although there is growing evidence that metals can be toxic to various aquatic species, there is still insufficient knowledge to integrate this information in environmental risk assessment procedures. In this study, we have investigated lethal Concentration (LC50) and toxicity effects of vanadium on mortality and growth of Artemia urmiana and Artemia franciscana. The in 24 h of A. urmiana and A...

To determine the potentially lethal level of thinner concentration in the air, we measured the concentration of toluene in the blood and others of three patients who suffered severe acute thinner intoxication between 4 January 1996 and 21 April 1997 in Ube city. The concentration of toluene in blood were 30.2 mg/L in died patient, and 13.7 mg/L and 17.5 mg/L in recovered patients, respectively....

The available data on the combined action of rare earth elements and heavy metals are contradictory. Therefore, goal presented work is relevant – to determine effects solutions copper, lanthanum salts their equimolar mixtures under controlled conditions for Daphnia magna Straus. It has been established that death D. over 50% in containing Cu2+ observed at a calculated concentration 0.05 mg/L (0...
