Abstract The purpose of this study was to examine the capacity of live brine shrimp Artemia spp. to accumulate metronidazole at different developmental life stages. Metronidazole is used in fish as an antiparasitic medication. An effective drug delivery method is to enrich the Artemia with metronidazole and offer them as live feed to the infected fish, usually ornamental species and other small fishes. Artemia cysts were hatched and then soaked in a metronidazole solution (0.05%) at instars 1–3 of larval development. Our findings indicated that Artemia were able to accumulate metronidazole at levels considered therapeutic to other animals and humans (25–100 mg/kg). However, the levels varied depending on the stage of larval development. Artemia accumulated the highest levels of metronidazole (137–143 mg/kg) when they started filter feeding (instar 2), whereas newly hatched Artemia (instar 1) contained the lowest level (85 mg/kg). Based on this study and a review of the literature, a new protocol recommended for enriching Artemia with metronidazole consists of soaking the Artemia in a 0.05% metronidazole solution for 3 h at room temperature. Because metronidazole is relatively insoluble in water, it must first be dissolved in warm water with continuous stirring. Received December 5, 2010; accepted January 30, 2011 相似文献

Exposure and ecological risks to heavy metals (copper, zinc, manganese, iron) at Lochnivar and Blue Lagoon National Parks in wildlife dependent on the Kafue river contaminated with mining waste was evaluated. Samples included water, fish, grasses and Kafue Lechwe (Kobus leche kafuensis) liver. At both parks copper ranged from 0.03-0.04 mg/l; 3.0-6.0 mg/kg; 11.0-44.0 mg/kg; trace -199.0 mg/kg; while zinc was 0.01 mg/l; 32.0-82.0 mg/kg; 15.0-21.0 mg/kg; and 52.0-138.0 mg/kg; in water, fish, grasses and lechwe, respectively. Manganese ranges were 0.15-0.16 mg/l; 7.0-18.0 mg/kg; 51.0-145.0 mg/kg; and 40.0-53.0 mg/kg while iron ranges were 0.13-0.14 mg/l; 26.0-134.0 mg/kg; 1766.0-1797.0 mg/kg; and 131.0-856.0 mg/kg; in water, fish, grasses and lechwe, respectively. Levels in all samples except water were high indicating potential for adverse effects. 相似文献

Spot-on application has proved to be an effective way to reach therapeutic doses of metronidazole and levamisole in fire-bellied toads. The percutaneous absorption of metronidazole and levamisole was quantified, using an aqueous solution of 1.008 mg/ml of metronidazole and an aqueous solution of 3.767 mg/ml of levamisole. High Performance Liquid Chromatography (HPLC) analysis of the percutaneous absorption revealed that of the amount applied, 75% of metronidazole and 90% of levamisole was absorbed. This resulted during 3 days of application in dosages of 23 mg/kg BW of metronidazole and 94 mg/kg BW of levamisole. Of the absorbed substances, 48% of metronidazole and 9% of levamisole were excreted in urine and faeces as unmetabolised substances. 相似文献

Serum and peritoneal fluid concentrations of metronidazole were determined in 6 healthy adult horses given the drug (25 mg/kg) by IV or oral routes. The disposition of metronidazole in horses given the drug by the IV route conformed to a 2-compartment model with a distribution half-life of 0.16 hours, an elimination half-life of 2.9 hours, and a body clearance of 0.40 +/- 0.05 L/kg/hr. The oral absorption half-life was 0.40 hours, and the bioavailability, 85.0 +/- 18.6%. Peritoneal fluid concentrations were approximately equal to serum concentrations at all times, regardless of the route of administration. On the basis of reported minimal inhibitory concentrations for anaerobic bacteria, a dosage of 15 to 25 mg/kg given orally 4 times daily was recommended. 相似文献

Serum concentrations of metronidazole were determined in 6 healthy adult mares after a single IV injection of metronidazole (15 mg/kg of body weight). The mean elimination rate (K) was 0.23 h-1, and the mean elimination half-life (t1/2) was 3.1 hours. The apparent volume of distribution at steady state was 0.69 L/kg, and the clearance was 168 ml/h/kg. Each mare was then given a loading dose (15 mg/kg) of metronidazole at time 0, followed by 4 maintenance doses (7.5 mg/kg, q 6 h) by nasogastric tube. Metronidazole concentrations were measured in serial samples of serum, synovia, peritoneal fluid, and urine. Metronidazole concentrations in CSF and endometrial tissues were measured after the fourth maintenance dose. The highest mean concentration in serum was 13.9 +/- 2.18 micrograms/ml at 40 minutes after the loading dose (time 0). The highest mean synovial and peritoneal fluid concentrations were 8.9 +/- 1.31 micrograms/ml and 12.8 +/- 3.21 micrograms/ml, respectively, 2 hours after the loading dose. The lowest mean trough concentration in urine was 32 micrograms/ml. Mean concentration of metronidazole in CSF was 4.3 +/- 2.51 micrograms/ml and the mean concentration in endometrial tissues was 0.9 +/- 0.48 micrograms/g at 3 hours after the fourth maintenance dose. Two mares hospitalized for treatment of bacterial pleuropneumonia were given metronidazole (15.0 mg/kg, PO, initially then 7.5 mg/kg, PO, q 6 h), while concurrently receiving gentamicin, potassium penicillin, and flunixin meglumine IV. Metronidazole pharmacokinetics and serum concentrations in the sick mares were similar to those obtained in the healthy mares. 相似文献

Abstract The effects of dietary zinc and calcium on immunocompetence of channel catfish Ictalurus punctatus (mean initial weight = 3.1 g/fish) were determined after a 10-week feeding trial. Fish were fed daily amounts equal to 3% of their body weight of one of six purified diets that were deficient in zinc (2 mg/kg of diet), calcium (0.02% of diet), or both; replete with zinc (20 mg/kg of diet) and calcium (0.5% of diet); or excessive in zinc (200 mg/kg of diet) or calcium (2.5% of diet). Immunocompetence of immunized and nonimmunized fish fed the various diets was assessed by measuring serum immunoglobulin M levels and mortality after an intraperitoneal injection of live Aeromonas hydrophila. Channel catfish fed diets deficient in zinc, calcium, or both had significantly (P ≤ 0.05) less weight gain and survival as compared with those fed diets replete with or excessive in zinc or calcium. Tissue mineral concentrations of fish indicated that various levels of zinc and calcium nutriture existed when immune functions were tested. Diet affected mortality of only nonimmunized fish in the bacterial-challenge test; zinc deficiency and calcium excess decreased mortality. Whereas growth and survival of fish were reduced by dietary zinc or calcium deficiency, the measured immunological characteristics were not equally impaired by these mineral deficiencies. 相似文献

We have shown previously that diets in which the nitrogen portion is based on synthetic dipeptides (PP) resulted in weight gain by rainbow trout alevins when free amino acid (FAA) based diets did not. However, the protein‐based diet used as a control in the previous study resulted in a significantly better performance of fish than peptide‐ or FAA based diet fed fish. Therefore, the objectives of our study were (i) to test how stomachless fish respond to peptide‐based diets, (ii) to evaluate PP and protein‐PP mixture diets and (iii) to examine if post‐prandial response to FAA concentrations in the fish body can be used as an indicator of the availability of dietary amino acid sources. The first experiment was conducted with a 4‐day old Koi carp (Cyprinus carpio) larvae and included groups fed a casein–gelatin (CG) based diet, a commercial diet and live Artemia nauplii. In the second experiment, fish fed live Artemia for 3 weeks (69 ± 12 mg) were placed in glass aquaria in triplicate per dietary treatment. Four diets provided equivalent amounts of nitrogen in the form of a CG, a PP, a 50% PP and 50% CG (PP50) mix and as FAA. Fish were fed at 1 and 3 h intervals, and the survival and growth were monitored during the second and third weeks of experiments 1 and 2 respectively. Following the completion of feeding, juvenile carp were sampled prior to feeding and 3 h after a meal. Whole body FAA analyses were carried out. We observed marginal suitability of the CG diet for larval Koi carp, as earlier indicated in common carp. Juvenile Koi carp fed the CG diet achieved 236 ± 19 mg, whereas PP50, PP and FAA diet fed fish grew to 140 ± 37, 70 ± 8 and 73 ± 5 mg respectively. Free amino acids in the fish body, and in particular indispensable amino acids (IDAA), were excellent indicators of dietary availability. The present experiment shows that a dietary 1:1 ratio of protein to synthetic PPs results in better growth, survival and whole body IDAA concentrations in relation to FAA‐ and PP‐based diets confirming earlier reports on the use of synthetic PP‐based diets, although this diet does not match the performance of complete protein, CG‐based diet. 相似文献

Although species-specific aquaculture production systems typically operate over reduced geographical ranges relative to many other terrestrial animal production systems, it is nonetheless often necessary to transport live fish between facilities by road to permit on-growing or finishing. Road transport is therefore common in Australian salmonid (trout and salmon) production and is a particularly significant feature of Atlantic salmon (Salmo salar) culture in Tasmania, where it is necessary to transport juvenile fish (smolts) from inland freshwater hatchery facilities to coastal marine farms for grow-out to slaughter.The most obvious respect in which road transport of live fish differs from that of terrestrial livestock is the requirement to provide a life-support system for the duration of the process. Aside from an inherent requirement for water, it is essential to provide oxygenation to support basic respiration. Thereafter, water quality must be managed to limit the accumulation of potentially toxic metabolites. Among these, carbon dioxide (CO2) is of particular concern. Without appropriate management, CO2 can rapidly accumulate to levels as high as 80 mg/L-1 and result in hypercapnia, respiratory dysfunction, narcosis, and ultimately death. Current life-support systems typically function to maintain CO2 at acceptable levels of 20-30 mg/L-1. Water temperature changes during and at the end of the transport process may also be an issue but are typically only a relatively minor consideration.In common with other livestock transport systems, the loading process and associated handling can evoke a physiological stress response which, though intended to be adaptive, may interact synergistically with aspects of the life-support system. Increased rates of oxygen consumption and CO2 excretion place additional demands on the life-support system while, from the fish's perspective, the changes in gill perfusion and circulation that facilitate such alterations in gas exchange can also operate to increase solute loss and result in diuresis and ionoregulatory dysfunction. As a consequence, once a suitable life-support system has been provided, the efforts of salmon farmers are focused on the need to minimize handling stress. The majority operate sophisticated pumping and counting systems that are intended to minimize aerial exposure of fish and, in a manner consistent with the natural behavior of the animal, mimic as far as is practicable the process of being washed downstream. 相似文献

Two experiments were conducted to study the interaction between dietary lutein and fat levels in broiler chicks hatched from lutein depleted (Experiment I) and repleted (Experiment II) eggs. In both experiments, a 2 x 3 factorial arrangement of treatments resulted in six dietary treatments (fat at 3% and 6% and lutein at 0, 25 and 50 mg/kg feed) that were fed for 23 days to 18 birds per treatment (in three replications). In Experiment I, the anti-dinitrophenyl-keyhole-lympet-hemocyanin (anti-DNP-KLM) serum antibody response at day 22 and macrophage phagocytotic index at day 17 did not differ among treatment groups (p > 0.05). The concavalin A and phytohaemagglutinin-P lymphocyte proliferation index at day 19 was greater in birds fed 50 mg of lutein and 3% fat than in birds fed all other diets (p < 0.05). Independent of the level of dietary fat, dietary lutein increased macrophage (day 23) nitrite production measured 46 h after in vitro stimulation with LPS (p < 0.05). Among the birds fed lutein at 25 or 50 mg/kg feed, birds fed 3% fat had higher LPS-induced nitrite production compared to the birds fed 6% fat after 46 (p = 0.014) or 70 h (p < 0.001). In Experiment II, macrophage nitrite production was measured at 54 h after LPS stimulation on days 11, 15, 19 and 23. An interaction between dietary lutein and fat levels on nitrite production was observed on day 19 (p = 0.012), where macrophages from birds fed 0 mg lutein and 3% fat had the highest nitrite production (p = 0.012). Macrophages from birds fed lutein at 25 and 50 mg/kg diet and 3% fat had higher (p = 0.012) nitrite production than birds fed 6% fat. Thus, in birds hatched from lutein deplete and replete eggs, modulation of macrophage nitrite production by lutein is dependent on the level of dietary fat. 相似文献

Pharmacokinetics, tolerance and serum thromboxane inhibition of carprofen in the dog 总被引:1,自引:0,他引:1

The non-steroidal anti-inflammatory drug (NSAID) carprofen was administered to dogs as a mixed-micelle solution at a dose rate of 0–7 mg/kg intravenously, as a palatable paste at a dose rate of 0–7 mg/kg orally, and as an oral tablet formulation at a dose rate of 0–7 mg/kg and 4-0 mg/kg orally for pharmacokinetic studies. It was also administered as an oral tablet formulation at a dose rate of 9-0 mg/kg orally daily for 14 days in a tolerance study. The pharmacokinetics following intravenous administration at a dose rate of 0–7 mg/kg indicate that carprofen has a small volume of distribution (Vd area = 0–09-0-25 litres), a slow systemic clearance (Cls = 1–34-5-57 ml/min) and an elimination half-life of 3–20-11-77 hours. Both oral paste and tablet preparations were highly bioavailable and absorption was proportional to dose rate at 0–7 mg/kg and 4-0 mg/kg bodyweight. Given once daily at dose rates likely to be used clinically it is unlikely to accumulate in the plasma. Carprofen administered as a palatable paste at a dose rate of 0–7 mg/kg did not inhibit serum thromboxane generation and this drug may therefore have a mode of action different from most NSAIDs. Carprofen was well tolerated when administered as an oral tablet formulation at a dose rate of 9.0 mg/kg daily for 14 days in healthy beagle dogs. 相似文献

Abstract The effectiveness of praziquantel (Droncit) against yellow grubs Clinostomum complanatum and unidentified, encysted, larval trematodes was tested in infected sunshine bass Morone chrysops female × M. saxatilis male. Praziquantel treatments significantly reduced the total number of live grubs in the fish in most treatment regimes tested. Treatment at 0.25 mg/L for 24 h was as effective as one at 8 mg/L for 8 h. Mature dead and dying metacercaria may have released toxins that killed host fish in some treatments. 相似文献
