The effects of safflower (Carthamus tinctorius) ethanolic extract on non-specific immune system of rainbow trout (Oncorhynchus mykiss).
Authors
Abstract:
In the present study, the effect of the intraperitoneal injection of Carthamus tinctorius extract on non-specific immune system and some serological of Oncorhynchus mykiss has been investigated. To this end, the fish with average weight of 100±10 gr were intraperitoneally injected by different levels of safflower extract. In this regard, a negative control group (no injection), a positive control group (injection with 0.2 ml physiologic serum) and three treatment groups received injections of C. tinctorius extract with the concentration of 50, 100 and 200 (mg/kg weight in the volume of 0.2 ml) respectively. Blood sampling were taken On the third, seventh and tenth days after injection, and total serum protein, total immunoglobulin, lysozyme activity, complement and blood glucose levels determined. The results showed that safflower extract injection led to a significant decrease in the number of white blood cells on the third, seventh and tenth days after injection (sig< 0/05). Moreover, blood glucose, lysozyme activity, total immunoglobulin and total protein levels significantly decreased. There was no significant change in complement activity among all groups. Considering this results, the use of safflower extract in rainbow trout can reduce and non-specific immune system activities.

Rainbow Trout, Oncorhynchus mykiss
Rainbow trout are classified as Oncorhynchus mykiss, and as such belong to the same genus as Pacific salmon, and to the family Salmonidae, which includes Atlantic salmon (Salmo salar), various trout (Salvelinus sp.), Arctic char (Salvelinus alpinus), Arctic grayling (Thymallus arcticus) and whitefish (Coregonus sp.). Rainbow trout are native to areas around the North Pacific Ocean, from souther...

Non-specific Immune Response of Rainbow Trout (Oncorhynchus Mykiss) by Dietary Heat-inactivated Potential Probiotics
Background: The effects of the dietary administration of two heat-inactivated whole bacteria from the Vibrionaceae family, singly or combined, on innate immune response of the rainbow trout were studied. The two bacteria (Pdp11 and 51M6), which were obtained from the skin of rainbow trout, showed in vitro characteristics that suggested they could be considered as potential fish probiotics. Meth...

Increased selenium (Se) concentrations in water (>10 microg/L) have been measured in the San Diego Creek, which is a tributary of the Upper Newport Bay in Orange County, CA. The objective of this study was to develop tissue- and dietary-based thresholds for Se in resident fish species in San Diego Creek. A 90-day dietary experiment was conducted to determine the effects of seleno-L-methionine (...

Watercress (Nasturtium nasturtium) is a medical plant containing diverse chemically-active substances with biological properties. The present study was conducted to investigate the immunomodulatory effects of watercress extract on immunological and hematological parameters of rainbow trout (Oncorhynchus mykiss). Fish were fed for 21 days with diet supplemented with 0.1% and 1% of watercress ext...

In this study, the immune reactions of rainbow trout (Oncorhynchus mykiss) were examined, after exposure to 10, 30 and 70% of tertiary-treated municipal sewage effluent for 27 days. Exposures were conducted concurrently with and without an immune challenge using intraperitoneal injections of inactivated Aeromonas salmonicida salmonicida. Due to the time required to prepare and analyse samples, ...
