Animal treatment

Animal treatment. Male 100-g MRC-Wistar or Sprague-Dawley rats were fasted from the evening of the previous day but were given water. Non-fasted 30-35 g Swiss mice were used. Except where specified otherwise, the animals received a standard commercial diet (Wayne Lab Blox, Allied Mills). In the standard experiments, animals were gavaged with 25 mg morpholine (Fisher Scientific Co.) in 10 mL water/rat or 2 mg morpholine in 0.2 mL water/mouse. A stream of NO2 was prepared by suitable mixing (using Teflon tubing) of gas from a cylinder of 106 ppm N0 in N (Linde Division, Union Carbide Corp.) and compressed air.

In addition, treatment of animals with phenobarbital not only increased overall rates of metabolism and clearance, but also shifted the metabolite patterns. One of the more common methods used for determining an exposure to (or the amount of a metabolite produced) is to determine an area under the curve (AUC) for the metabolite. Further, one of the more common methods for representing a racemically preferred metabolite is to calculate the ratio of the R to the S. For example, the 3-decholoro metabolite of ifosfamide was produced in higher amounts from the R enantiomer while the 2-decholorometabolite was the major metabolite produced from the R enantiomer in naive animals. Treatment with phenobarbital shifted the metabolism so that the 3-dechloro metabolite was no longer the major metabolite for the S enantiomer. 

FIGURE 12.2 Responses of beavers to predator chemicals applied to aspen sticks. Activity periods were consecutive 5 days of experiment in two areas in New York and the percentages of sticks consumed is the mean of several replications of the experiment. All treated sticks were punctured to improve the uptake of chemicals intact sticks were untreated (A), punctured but not treated ( ), punctured and treated with the solvent methanol ( ) (the three controls), or treated with extracts from other animals. Treatments that inhibited consumption most were excrement extracts from lynx (+) and coyote ( ... ), both sympatric predators (lynx now extirpated). Beavers accepted most readily the three control sets. Other chemicals were from otter (o), wolf ( - ), lion ( ). (From Engelhart and Miiller-Schwarze,...

Thirty-seven weeks after ovariectomy, marked decreases of 73% (p <. 01) and 77% (p <. 01) in trabecular bone volume and trabecular bone number (data not shown), respectively, were observed at 1 to 5 mm of the growth plate metaphyseal junction of the proximal tibia. Simultaneously, a marked increase in trabecular bone separation from a control value in intact rats of 262 19 to 1486 236 pm (p <. 01) was observed in OVX animals. Treatment with 1 mg/kg of EM-800 and raloxifene resulted in 68% (p<. 01) and 64% (p <. 01) reversals, respectively, of the decrease in trabecular bone volume caused by ovariectomy. In fact, treatment with EM-800 and raloxifene at the daily 1 mg/kg dose increased trabecular bone volume of the proximal tibia from a control value of 5.8 0.9% in OVX animals to 16.4 0.4% and 15.8 1.0%, respectively. These stimulatory effects are not statistically different from the 53% reversal achieved with E2. At the lowest dose used (0.01 mg/kg), EM-800 already reversed by 34% (p <. 01) the elfect of OVX whereas raloxifene had no detectable effect. The administration of 0.1 mg/kg of EM-800 and raloxifene, on the other hand, resulted in 40% (p <. 01) and 24% (p <. 05) reversals, respectively, of the decrease in trabecular bone volume caused by OVX. 

That the development of bacterial infections in iron-treated animals is caused by the alleviation of iron-starvation for infecting bacteria rather than by the neutralization of defense mechanisms by iron has been shown most clearly in siderophore-treated animals. Treatment of mice with enterochelin produced no observable effect in uninfected mice whereas in infected mice, E. coli grew logarithmically, and the animals died within 18 hr. This iron-binding compound facilitated the development of the overwhelming infection by being able to remove iron from Tr (8). 

The type of dosage form, the route of administration, and site of injection of parenteral preparations depend on the animal species or group of related species (such as ruminant animals or poultry). The greatest differences relate to oral dosage forms and topical preparations. Whether a veterinary dosage form is intended for individual animal treatment or for...

Delayed treatment with multiple doses of DTPA removes moderate amounts of plutonium from animals. Treatment of swine on five successive days two months after plutonium contamination removed 11—19% of the plutonium 9S). The body burden of rats was reduced to 60% of the controls by treatment with DTPA administered on day 6, 8 and 11 after the plutonium injection99). The largest decrease of plutonium was found in the soft tissues, but skeletal removal was more difficult, and the moderate amounts removed may not significantly reduce the number of bone tumors formed59 100 101). Further details on the use of DTPA in removing internally deposited plutonium may be gained from other reviews6 13 102 103).

Commercial extract dosages Extensive animal treatment has shown that high levels can be tolerated in the treatment of acute disease in farm stock. The usual dosage for humans is much smaller. 

Animal Treatment Male Sprangue-Dawley rats (200-250g) were intravenously administered paraquat dlchloride (5 mg/kg) dissolved in saline. They were sacrificed 3 h, 12 h, 24 h, 3 days, 7 days and 10 days after injection and the tissues (lung and brain) were removed. 

Cardiovascular disease in animals has been found to be related to physical, emotional, and behavioral stresses (Nerem et al., 1980). Rabbits that were held, petted, and coddled were found to have a 60% reduction in atherosclerotic lesions compared to their control counterparts, despite comparable serum cholesterol, heart rate, and blood pressure levels. These results demonstrate that psychosocial environments of animals can have profound effects on health, and that these environments (animal treatments) must be controlled during scientific studies in order to avoid drawing erroneous conclusions. 

HPPD catalyzes an early step in a tyrosine degradation pathway [12] that is widely distributed in nature [13] and thus, as in animals, treatment of plants with inhibitors causes significant accumulation of tyrosine [8, 14]. HPP derived from transamination of tyrosine, is converted into HGA via HPPD, HGA is oxidized via HGA oxidase to 4-maleylacetoacetate, which is further degraded via 4-maleylacetoacetate isomerase and 4-fumarylacetoacetate lyase to fumarate and acetoacetate. In microbes the pathway provides assimilable carbon from tyrosine...
