Five autopsy cases showing more than 20 hepatocellular mitotic figures per 1 cm2 of liver parenchyma had also widespread skeletal muscle necrosis and renal failure. Myoglobin casts in renal tubules were remarkable. In three of these cases liver cell damage was obvious, but in two others it was negli gible. Mechanisms of muscle necrosis were probably different from case to case. For a control st...

1. Rats fed l-cystine at excessive levels excrete large amounts of sulfate sulfur in the urine and develop liver necrosis and cirrhosis. 2. Rats fed dl-methionine at excessive levels excrete large amounts of sulfate sulfur, but do not develop liver necrosis and cirrhosis. 3. Rats fed cysteic acid at high levels excrete relatively small amounts of sulfate, but do develop liver necrosis and cirrh...

persian sturgeon, acipenser persicus is a native, commercially important and highly steemed fish species in the caspian sea. in this study, effects of nodularin (nodln), a cyclic pentapeptide hepatotoxin, on liver and gill tissues of a. persicus were studied. nodularin was produced in high amounts by nodularia spumigena, a cyanobacterium species during the algal bloom in the caspian sea and was...

in the february 2006 in two wetlands in northern iran, the mortality among wild swans was observed. paralysis was the most prominent feature of the disease. histologically, diffused necrosis of acinar cells in pancreas, degeneration and necrosis of some neurons in central nervous system (cns), sever necrotic and hemorrhagic enteritis, foci of haemorrahge and myocardial cell necrosis in the hear...

background: the aim of the present study was to find the effects of cadmium (cd) on japanese quail on the role of an animal model in order to understand the toxicity of cd in creatures presented, within the environment. methods: one hundred 30-day-old male japanese quails were equally divided into the control group and cd group. the control group received no cd while the cd group was given form...

copper sulfate is one of the most important pollutant in aquaculture systems. the aim of the present study was of the histopathological changes of some organs of common carp. copper sulphate can be considered as a toxic agent for fish.the effect of copper sulphate at 0. 0 1 mg/l as a constant bath was studied on common carp (cyprinus carpio) weighing about 100g. at 19±1°c for one month. tissue ...

The need of aquarists for proper and safe disinfection of fish with Chloramine-T (CL-T) necessitates toxico/pathologic examinations.   This study assays toxicity level of CL-T and histopathologic changes of gills, liver, kidney and brain of treated zebrafish (Danio rerio). Groups of 10 Zebrafish were treated with 0 (control), 5, 10, 15, 30, 50,100 and 200 mg/L of CL– T. Mortality was recorded a...
