In cases of decomposed bodies Y chromosomal STR markers may be useful in identification of a male relative. The authors assessed typeability PowerPlex Y (Promega) loci in tissue material stored in water and soil environment. Tissue material was collected during autopsies of five persons aged 20-30 years with time of death determined within the limit of 14 hours. Heart muscle, liver and lung spe...

The histopathological effects of Linear Alkylbenzene Sulfonate on the gill, liver and kidney tissues of the Caspian kutum, Rutilus frisii kutum were studied. The fish were exposed to three sublethal concentrations of anionic detergent, Linear Alkylbenzene Sulfonate (LAS) for short term intervals (192 h). Gill, liver and kidney samples were collected after 192 h of exposure to LAS and lesions we...

The major objective of this study was to investigate heavy metal content of black pomfret (Parastromateus niger ). The concentrations of Zn, Cu, As and Cd were determined in external (gill and shell) and internal organs (muscle and liver) of black pomfret in northwest of Persian Gulf in summer 2013. A total of 60 specimens were collected from fishing bottom trawlers. Concentrations of these hea...

lead is one of the heavy metal that is very toxic for environment and organisms. lead can inhibits many physiological processes and it is so dangerous for body tissues. in this study, four groups of fish (carassius auratus) 35 in each, were used for experiment. group 1 was as control, in group 2 fishes were exposed to lead acetate at concentration of 8. 5 mg/l, fishes in group 3 and 4 were also...

at first, in order to define acute toxicity of diazinon insecticide and butachlor herbicide, acute toxicity tests (lc5096h) were done, based on standard method (1989) o.e.c.d. in static way and for 96 hours. and the amount of acute toxicity (lc5096h) of diazinon and butachlor in 1 to 2 gram vimba vimba persa fry larva was determined to be 0.09 and 0.61 respectively. in order to do histology stu...

Tissue metal accumulations (gills, liver, kidney and muscle) in Persian sturgeon (Acipenser persicus) were compared folowing exposure to sublethal levels of waterborne Cd (50, 400 and 1000 μg•L-1) after periods of 1, 2, 4 and 14 days. The obtained results indicate that at the end of 4 and 14 days of exposure, total tissue cadmium concentration followed the pattern: liver > gill > kidney > muscl...

diazinon is one of the highly consumed organophosphorous pesticides. it inhibits cholinesterase enzyme in animal tissues. due to permanent residence in agricultural drainage channels, the swan mussel (anodonta cygnea) can be considered as one of the most suitable indicators of such pollutants. at the present study, acethyle cholinesterase activity of a. cygnea was measured when exposed to vario...

in this study gill-net selectivity for alburnus chalcoides inhabiting the almus dam lake was estimated. experimental gill-net fishing was conducted using gill-net with 15 mm and 20 mm mesh-size, during october 2002 and september 2003. a total of 254 and 198 specimens of a. chalcoides were caught by gill-net with 15 mm and 198 with the 20 mm mesh-size, respectively. the total length of the fish ...
