Anthropogenic activities can increase the salinity of freshwaters. Thus, freshwater fish Oreochromis niloticus were exposed to Cd (1.0 μg/mL) in increased salinities (0, 2, 4 and 8 ppt) for 0, 1, 3, 7 and 14 days. Following single and combine exposures to salinity and Cd, Na/K-ATPase, Mg-ATPase, Ca-ATPase activities were measured in the gill, kidney and intestine. In general, salinity alone exp...

neuroendocrine tumors are most often located in the intestine and lungs but they can arise from other areas of the body. limited data is available on epidemiology and clinical patterns of neuroendocrine tumors in iran. we analyzed medical records of 34 patients from 2 cancer centers (emam khomeini hospital and omid charity cancer center) in west azarbaijan province of iran with neuroendocrine t...

Few reports have been published regarding the investigation on the enzymes of viscera of cuttle-fish, Ommastrephes sloani pacificus. OSHIMA et a11) have pointed out the existence of proteinase and amylase in the viscera, and NARA2) has investigated on the proteolytic enzy mes of the liver and reported the presence of cathepsin like enzymes. The present paper deals with the proteolytic activity ...

We investigated the effects of Cu2+-loaded silicate (CLS) on the growth performance, microflora of skin, gill and intestine, and intestinal morphology of crucian carp Carassius auratus. A total of 225 native wild crucian carp, with an average initial body weight of 20 g, were randomly divided into 5 treatment groups using 3 replicate tanks of 15 fish per group. The dietary treatments were (1) b...

Experimental infections with a birnavims strain isolated from turbot (Scophthalmus maximus) were conducted by immersion and intraperitoneal injection in turbot. Virus could be recovered in skin, mucus and intestine from fish infected by immersion, only up to 3 days post-infection. The distribution in internal organs was fast after intraperitoneal injection and virus was recovered with high titr...

The study describes the infection of the acanthocephalan, Neoechinorhynchus agilis sp. The (grey mullet) Mugil cephalus is highly valued food along the Corentyne coast, Berbice, Guyana. The fish Mugil cephalus were collected from Bush Lot, Whim, 43 Village 63 Beach and 79 Village, Corentyne coast. The infections with the parasites were observed in posterior region of the intestine, liver and mu...

The orange-spotted grouper (Epinephelus coioides) is an important marine farmed fish in China. It affected by the bacterial pathogen Vibrio alginolyticus, which causes high mortality and substantial economic losses. We studied transcriptional changes of IgZ gene E. coioides following V. alginolyticus stimulation investigated distribution different tissues. highest expression level occurred head...
