Control animals

NOTE Data are expressed as pereent of values in eontrol saline-treated rats and represent the mean SEM from four to six animals. Control levels of 5-HT uptake sites were 356 15 fmoEmg protein. 

It has long been established that the sexual status of an animal controls and coordinates its growth rate and speed of fattening. Bulls grow faster and lay down more lean meat in the carcass than steers, whereas steers grow faster with a higher feed conversion efficiency than cows. These beneficial effects on animal performance are due to the sex steroids produced in the testes. 

The validity of a specific method should be demonstrated in laboratory experiments using test samples or standards that are similar to the unknown samples analyzed in the routine. For example, control tissue samples from non-treated animals, control tissue samples spiked with the analyte at several known concentrations, and dosed or incurred tissue samples from animals that have been treated with the drug, should all be available to the analyst before starting a validation process. All these samples will enable the analyst to define the background noise, to identify the amounts of the analyte added to the control tissue, and demonstrate that the method can satisfactorily recover the biologically incurred residue.

With any suspicious outbreaks, the local health department, poison center, law enforcement agency, and US Federal Bureau of Investigations (FBI) should be contacted immediately. Due to the absence of a nationwide surveillance system for animal diseases, the responsibility for detecting possible outbreaks of unusual symptoms in animals will fall over several different groups of people. Farmers, agriculture officials, veterinarians, animal control officers, wildlife rehabilitators, (animal) poison control centers and the lay public (animal owners) may all be involved in detecting outbreaks. 

Individuals with ongoing risk of exposure—either continuous risk (e.g., research laboratory staff or those involved in rabies biologies production) or individuals with frequent exposures (e.g., those involved with rabies diagnosis, spelunkers, veterinarians, animal control workers, and wildlife workers in rabies-enzootic areas) should undergo serologic testing every 6 months and 2 years, respectively, to monitor rabies antibody concentrations. An IM or intradermal booster dose is recommended if the complete vims nentralization is below 1 5 semm dilution by the rapid flnorescent foens inhibition test.

Never turn your back on a dog. Act confident when you are around dogs. If you are bitten, immediately wash the wound thoroughly with soap and warm water. Contact your physician for additional care and advice, and report the incident to your supervisor. The bite should also be reported to your local animal care and control agency. Tell the animal control official everything you know about the dog, including the owner s name and address. 

In monogastric animals, control is mainly metabolic. In the short term, blood concentrations of glucose and other nutrients may control intake via the hypothalamus. In the longer term, fat depots send signals to the brain by the hormone messenger leptin. 

On cooling the enviromnent of the cell membrane to just below the normal ambient temperature, the head groups become arranged in a more ordered hexagonal manner and the hydrocarbon chains become more straight. The temperature of the liquid crystal phase to gel phase transition depends upon the environment of the organism concerned. For example, homeothermic animals control their own body temperatures and so the cells are... 

Outdoor grounds have some other special considerations. Animals must be kept out of playground areas. Stray dogs should be reported to animal control, but fences should extend to the ground and have stakes or cables to secure fencing to the ground and prevent access under the fence. Homes around schools should also be required to keep animals in fences, in kennels, or on leashes. 

In laboratory animals, controlled mechanical ventilation delivered for 1 to 11 days can decrease diaphragmatic force generation by 20-50% and can cause similar decreases in diaphragmatic endurance (40). Several mechanisms, including stmctural injury, muscle atrophy, and oxidative stress, appear to be responsible for ventilator-associated respiratory muscle dysfunction (40). Of interest, in a study of more than 200 critically ill patients— 80% of whom required acute ventilator support—duration of mechanical ventilation was nearly three days shorter in those who completed a 10-day antioxidant supplementation protocol (vitamins E and C) than in those who completed a 10-day course of placebo (76).
