This study investigated the effects of ATV on chronic liver and kidney damage induced by BaP. Materials and methods: In this experimental study, adult female rats w...
the present study was carried out in 2011 to measure concentration of heavy metals chromium and tin in liver and muscle tissue of liza aurata (golden grey mullet) in estuaries of the rivers babolroud, tajan and gorganroud. accordingly, after sampling the target are asandisolating muscle (18samples) and liver (18samples) tissues, they were digested and analyzed using graphite furnace atomic abso...
During radiotherapy by any radiation, it is always essential to stop absorbing the excess dose by a tissue. To better treat cancerous tissues and to make more precise irradiation for a cancerous tumor, there needs the accurate irradiation time to be estimated. First, the constituent materials of any of the existing organs in abdominal tissue are extracted and defined in the MCNPX code. Then, ev...
In this study, in order to determine the amount of 36 elements contamination in muscle and liver tissues Vimba persa in the southwestern coast of the Caspian Sea (Guilan Province), its relationship with growth indices (length and weight, condition factor and hepatosomatic index) were investigated. This study was conducted to determine the element concentrations in muscle and liver tissues...
Bioaccumulation of Cu, Zn, Hg in muscles and liver tissues of stellate sturgeon (Acipenser stellatus) from the southern Caspian Sea was measured. Effects of condition factor (CF), age and hepatosomatic index (HSI) on metal accumulation were also determined. Some 40 stellate sturgeons were collected using gill nets in winter and spring 2007-2008 from the southern shores of the Caspian S...
Zooplanktons have an important role in food chain of the aquatic ecosystems, which acts as a food chain link between producers (phytoplankton) and higher nutritional levels. The purpose of this research was to identify and study the zooplankton density in the southeastern basin of the Caspian Sea (Gorgan Bay). Sampling was performed seasonally and samples were collected by zooplankton net (36 c...
