چکیده
Forty-two years ago Lyndon B. Johnson was US President, a first class postage stamp cost 5cents, the first ‘Star Trek’ episode was broadcast and England defeated West Germany in the Soccer World Cup. Major changes were in the wind. The Beatles recorded ‘Eleanor Rigby’, ‘Yellow Submarine’ and ‘Good Day Sunshine’, marking the beginning of their metamorphosis. The War in Indochina intensified, with 400,000 US ground troops in South Vietnam. Worldwide student unrest began.

Monogenean infestations of arowana (Osteoglossum bicirrhosum) and cat fish (Hypostomus plecostomus)
Arowana (Osteoglossum bicirrhosum) and cat fish (Hypostomus plecostomus) are two species of ornamental fishes which are mostly imported to Iran. Monogenea are plathyhelminthes which can dominantly infest the fish skin and gills with high host specificity. In this research, 35 O. bicirrhosum and 50 H. plecostomus with clinical signs were collected from different ornamental fish markets in Semnan...
متن کاملProtective Effects of Dietary Spirulina platensis against Cadmium-Induced Oxidative Stress in Gills of Rainbow Trout
Background: Contamination of feeds with cadmium leads to oxidative stress in vital tissues such as gills and affects the fish survival. Therefore, an increase in the capacity of the antioxidant defense system and detoxification system of fish may reduce adverse effects of pollutants. This study investigated the protective effects of microalga Spirulina platensis against oxidative stress in gill...

متن کاملResearch Article: Morphometric study and identification of external parasites in Hypophthalmichthys molitrix breeders in Guilan, Iran
The parasites that normally cause fish disease under farming condition possess a direct life cycle with no need to intermediate hosts for dissemination. The ensuing infection can therefore spread rapidly inducing more damaging lesions in the external parts of host especially the gills. In this study, in order to isolate and identify foreign parasites of phytophagous fish in Guilan province, 4 f...
متن کاملSex hormone-binding globulin in fish gills is a portal for sex steroids breached by xenobiotics.
As in most vertebrates, plasma sex hormone-binding globulin (SHBG) is produced in fish liver and regulates sex steroid access to target tissues. Low levels of SHBG mRNA are present in zebra fish gills but are unlikely to account for the high amounts of immunoreactive SHBG in filaments and lamellae. Although the uptake of steroids by fish from water has been reported to correlate with their affi...
