LAT Chapter 1 & 2
Types of euthanasia modes of action
Hypoxia (CO2 inhalation), direct depression of neurons necessary for life (anesthetic overdose), physical disruption of brain activity (electrocution); methods of euthanasia are categorized by species and are deemed either acceptable or unacceptable for that species
IACUC suspension authority
In serious deficiencies, IACUC may suspend any animal-related activity, including an entire protocol. IACUC and the IO determine the appropriate action to be taken; suspension of animal activities require notification of USDA, OLAW and AAALAC. May have to return their grant money to NIH
OLAW responsibilities
monitor compliance with PHS Policy; expects institutions to self-regulate and report deviances from PHS Policy and Animal Welfare Assurance; inspects a handful of institutions randomly each year and conducts for-cause inspections
Archives
All protocols, raw data, specimens, documentation and final reports must be archived during or at the close of a GLP study; specimens must be kept for as long as reanalysis would yield sound information; biological fluids must be stored frozen; archives kept for 5 years after study completion if they support a research or marketing permit that was not approved, kept for 2 years after study completion if the study is not submitted for a marketing permit or is discontinued
Animal environment, housing and management
Physical environment includes the microenvironment and the macroenvironment, housing, temperature, humidity, ventilation, air quality, illumination, noise and vibration control. Housing considerations include caging, environmental enrichment, space and special considerations such as sheltered or outdoor housing and naturalistic environments
OLAW
was originally the Office for Protection from Research Risks (OPRR)
Ideal euthanasia agent
would rapidly induce loss of consciousness so death would follow quickly and present no hazards for personnel administering it.. however no drug exists
Language in The Guide
"must" is used to describe animal care program aspects that are essential or imperative to proper humane care and use of lab animals; "should" describes strong recommendations for achieving a goal
The research process
1. Define the question 2. Formulate an objective framework 3. Establish a hypothesis 4. Create a research design 5. Identify Variables 6. Collect and analyze data 7. Report data and conclusions
Euthanasia
A method of killing that minimizes pain, distress and anxiety experienced by the animal prior to loss of consciousness, and causes rapid loss of consciousness followed by cardiac or respiratory arrest and death.
Oversight of institutional research programs is done by...
Animal Welfare Act and Regulations, Public Health Service Policy, the Guide for the Care and Use of Laboratory Animals (the Guide), the Guide for the Care and Use of Agricultural Animals in research and teaching, and relevant institutional policies.
Animal Facility Definition according to PHS
Any building, room, area, enclosure or vehicle used for animal confinement, transport, maintenance, breeding or experiments in which animals are housed for more than 24 hours (as compared to 12 hours in the AWR)
Institutional Officer Responsibilities
As designated by the Guide, the IO bears ultimate responsibility for the animal care and use program; he or she has authority to allocate resources to the program and should provide leadership to program personnel
USDA Pain categories
Category B: animals being bred, conditioned or held for use in teaching, testing, experiments, etc but not yet used for those purposes Category C: Use but no pain or distress, so do not require pain-relieving drugs (example is vaccinations) Category D: Causing pain or distress to the animals but appropriate anesthetic, analgesic or tranquilizing drugs are used (ex. is surgery) Category E: Causing pain or distress but anesthetics, analgesics or tranquilizing drugs are not used because they would have adversely affected the procedures, results, or interpretations (inducing a disease)
Test system
Comprehensive term under GLPs referring to the animals or any other entity that is administered a substance in a GLP study. Test systems can also be a physical or chemical medium like soil or water
1979 revision of PHS
Definition of animal changed to include all vertebrates
AWR
Describes what a facility must do to comply with the AWA
Postapproval monitoring
Ensures that IACUC-approved procedures are being followed; the formal process is not required by federal mandate but AWR and PHS Policy do require the IACUC to continually review ongoing animal studies
Funding administration
For most institutions, there is usually an Office of Research and Grants led by a dean or vice president of research.
Institutional Animal Care and Use Committee
Has oversight responsibilities for the institution's research program and receives support from the administrative unit.
AWA Recordkeeping Requirements
IACUC records that must be kept on file include meeting minutes, proposed animal use protocols and significant changes to those protocols, semiannual reports, and any recommendations. USDA requires records for live dogs and cats and any offspring born of these animals at the research facility, as well as records of disposition for species covered by the USDA
Research facility requirements
If using animal species covered by AWA, must establish an IACUC, employ an attending veterinarian under formal arrangements, training for all personnel involved in animal care, treatment and use
Animal Welfare Assurance
In order to receive grant or contract involving the use of animals, recipient institution must file an approved Animal Welfare Assurance to commit the institution to compliance with the PHS Policy, AVMA Guidelines on Euthanasia, the Guide and the AWA; signed by the IO with OLAW
Protocol approval by IACUC
In planning a research study involving animals, scientists must submit an animal use protocol to the IACUC for review which must be approved in order for the PI to begin a study using animals
Annual report to USDA
Institutions using USDA-covered species must submit an annual report to USDA to demonstrate that it's following the AWA, its animal care meets professionally accepted standards, the PIs consider alternatives to painful procedures listed in the animal use protocols and that any exceptions to the regulations are approved by the institution's IACUC; must also state the location of all the institution's animal facilities and how many animals were used in the previous year under each USDA Pain Category
When was the AWA made and who enforces it?
Laboratory Animal Welfare Act of 1966 was amended in 1970 and changed to the AWA; the USDA implements and enforces this law
Class B animal dealers
Licensed by USDA to purchase and resell animals including random-source dogs or cats, import nonhuman primates and resell animals from research facilities
Protocol approval
May be approved for 1-3 years depending upon species used and institutional policies; protocols for USDA covered species may only be approved for 1 year
Identification of animals
Must be properly identified at acquisition, transportation, sale or disposal; any dog, cat or nonhuman primate transported to a research facility must be accompanied by a health certificate issued by a licensed veterinarian; USDA may provide exceptions to the health certificate requirement for animals with a health condition necessary for the approved protocol
Confirming death after euthanasia
Necessary before disposal of animal; a combination of criteria is most reliable to confirm death including lack of pulse, breathing, corneal reflex and response to firm toe pinch, inability to hear respiratory sounds and heart beat by use of stethoscope, graying of mucous membranes and rigor mortis. NONE of these signs alone, except rigor mortis confirms death
Regulations for interstate sale and transportation of animals
Rabies vaccination requirements for dogs and cats; health certificates provided for dogs, cats and nonhuman primates; transporting sick or infected animals or those exposed to any transmissible disease from another state or area is prohibited
IACUC review of animal care and use program
Required to monitor programs every 6 months through review of the program and routine inspections of the animal facilities; most highly visible responsibility or an IACUC
IACUC and the community
Serves as an information resource on animal welfare and a liaison on animal research concerns to the institution and the community
Good Laboratory Practices
Set of controls for research labs to ensure the consistency of procedures and reliability of data; FDA and EPA mandate these standards for safety testing on the types of commercial products each agency regulates; may conduct inspections of animal facilities and unannounced for-cause inspections. Some animal facilities operate exclusively under GLP regulations, while many others only conduct GLP studies from time to time
NSF (National Science Foundation)

PHS Policy
NIH Policy in 1971 was replaced by PHS Policy on Humane Care and Use of Laboratory Animals in 1973; required institutions using warm-blooded animals in research funded by NIH to provide an assurance that the maintenance and treatment of animals would be in accordance with the AWA and the Guide; Office of Laboratory Animal Welfare monitors compliance with PHS
Registration under AWA
Nonfederal research facilities must register with the USDA if using species covered by the AWA; registration must be updated every 3 years by submitting a new registration form that is signed by the IO, who ensures the organization is in compliance with the AWA
Facility inspections and program review
PHS policy and AWR require that IACUC conduct semiannual inspections of the animal facilities; the Guide states that inspections and program review should be performed at least annually; inspection findings are reported to the IO of the research facility, which are added to the institutional records and must be available during outside inspections; IACUC also conducts semiannual review of the research program's policies and procedures
Differences between AWA and PHS policy
-AWA requires 3 IACUC members while PHS requires 5 -AWA does not cover mice or rats bred for research, birds, farm animals, or horses not used for research, whereas PHS covers all vertebrates -Under AWA, the USDA and APHIS conduct annual, unannounced facility inspections; Under PHS, OLAW conducts random inspections of some institutions and for cause inspections -Under AWA, research facilities must register with USDA and re-register every 3 years; under PHS, research facilities must file and sign an Animal Welfare Assurance -the AWA is enforced by USDA and APHIS, and the PHS is enforced by OLAW

US Government Principles for the Utilization and Care of Vertebrate Animals Used in Testing, Research and Training
Incorporated into the PHS Policy in 1996 (the Guide also endorses these principles) -Transportation, care and use of animals should be in accordance with AWA and other applicable federal laws -Procedures should be designed and performed with due consideration of their relevance to human or animal health, the advancement of knowledge or the good of society -Animals selected should be of an appropriate species, quality and minimum number required to obtain valid results -Avoidance or minimization of discomfort, distress, and pain when consistent with sound scientific practices is imperative; assume that procedures that cause pain in humans also cause pain in animals; use appropriate sedation, analgesia, or anesthetics -animals that would otherwise suffer severe or chronic pain that cannot be relieved should be euthanized
Class A animal dealers
Licensed by USDA to raise and sell animals themselves (purpose bred animals)
IACUC mandates
Mandated by federal law and must adhere to guidelines, federal regulations and policies, and institutional policies that govern the use of animals in research; the IACUC's function are specified by both the PHS and USDA; The institutional official (IO) appoints the members to the IACUC and is ultimately responsible for the entire animal care and use program
Occupational Health and Safety in the Care and Use of Research Animals
Provides guidance on creating and implementing an institutional occupational health and safety program and addresses hazard control in the laboratory animal facility; should take into account the training and experience levels among employees, the possibility of exposure across the different areas of the facility, the types of research and animal species, including the presence of pathogens, radioisotopes and toxic chemicals; varies greatly among institutions
IACUC responsibilities according to the Guide
