The protective nature of Chironomus luridus larval tubes against copper sulfate.
The objective of this study was to determine whether the tubes in which Chironomus larvae dwell protect them against chemical toxicants. A laboratory culture of an Israeli benthic midge, Chironomus luridus, was exposed to copper sulfate. Two conditions were tested in bioassay experiments: larvae within silt tubes and larvae without tubes. The non toxic, anionic, fluorescent dye, fluorescein, wa...
متن کاملProtective effect of zinc supplementation against copper toxicosis in sheep.
1. A study has been made of the effects of dietary zinc supplementation on the development of copper toxicosis in three groups each of eight 12-week-old lambs. 2. None of the lambs receiving 420 mg Zn/kg diet developed Cu toxicosis in the 24-week experimental period, compared with three in the control group receiving 43 mg Zn/kg and possibly one in the group receiving 220 mg Zn/kg. 3. Liver Cu ...
متن کاملThe protective effects of saffron stigma alcoholic extract against vincristine sulfate drug-induced renal toxicity in rat
Introduction: Vincristine (VCR) is potential anti-cancer drug that is highly toxic for renal tissue. This study aimed to evaluate the protective effect of alcoholic extract of saffron stigma against vincristine renal toxicity in male rats. Methods: A total number of 50 rats were randomly divided into 10 groups. Different doses of VCR (0.25, 0.5 and 0.75mg/kg) and saffron (0.5 and ...
متن کاملHuman immunoglobulin G mediates protective immunity and identifies protective antigens against larval Strongyloides stercoralis in mice.
Protective immunity to larval Strongyloides stercoralis in mice has been shown to be dependent on antibody, complement, and granulocytes. The goals of the present study was to determine the following: (1) whether human serum could passively transfer immunity to mice, (2) the mechanism by which the serum mediated killing, and (3) whether the antigens (Ags) recognized by the protective human anti...
متن کاملShort communication: Efficacy of copper sulfate hoof baths against digital dermatitis--Where is the evidence?
Digital dermatitis is a major problem in modern dairy production because of decreased animal welfare and financial losses. Individual cow treatments are often seen as too time consuming by farmers, and walk-through hoof baths have therefore been used extensively to control digital dermatitis. For decades, copper sulfate hoof baths have been used to treat and prevent digital dermatitis. Copper s...
