Council of Animal Care (CCAC) guidelines. 1.1 To lay down a standard procedure to be followed for conducting Bioassay of Test Item for Human Chorionic Gonadotrophin (HCG) activity in experimental rats by the following method prescribed in Indian Pharmacopoeia (I.P. 3. In behavioral studies, food deprivation protocols are routinely used to initiate or maintain motivational states that are required in a particular test situation. 4.3. Learn vocabulary, terms, and more with flashcards, games, and other study tools. they note that on “This scald model has been used in previous DRDC experiments”. Draw up, into the syringe and needle, the amount of solution to be administered. This study investigated the effects of different lengths of food deprivation periods and restricted (fixed-time) feeding on … This step of society of the need for anesthesia, and was movable and exotic animal formulary carpenter pk. According to animal euthanasia guidelines [26, 27], rats were intraperitoneally injected with an overdose of pentobarbital sodium (200 mg/kg). The overwhelming majority of laboratory studies employing rodents end with killing the animals upon completion of the study or if a humane endpoint has been reached. This SOP follows the UBC and CCAC guidelines for the collection of blood in … Responsibility The CCAC updated their guidelines for both mice and rats. they also assure the CCAC … blood samples from the tip of the tail of rats. Rats will not stay on top of the wire-bar lid of the cage. Blood samples (0.3 mL each) were obtained from the catheter This procedure can be used to collect 5‐40 ul of blood per time point.

The study was performed in accordance with the Canadian Council on Animal Care (CCAC) guidelines, 1998. Mar 2020 (Human Research) - Guidance during COVID-19 Outbreak. The rats were quarantined and acclimated for 10 days prior to use. In their natural habitat, rats exhibit complex behaviours such as digging, burrowing, running, jumping, climbing, and stretching upright, among others, which have not been extinguished, despite hundreds of generations in captivity. The sympathetic–adrenal–medullary system likely is rapidly stimulated due to exposure to CO 2, 10, 14, 19, 22 but there are no significant differences dependent upon whether the rats experience euthanasia in either the home cage or induction chamber. Euthanasia in rodents is an ongoing topic of debate due to concerns regarding the aversive nature of gases with anesthetic properties such as carbon dioxide (CO2) and isoflurane. The CCAC can recommend that the federal granting agencies withdraw research funding from a non-compliant institution. During the second phase half the rats received lesions that were restricted to the medial prefrontal cortex. Generally, male laboratory rats will reach sexual maturity at approximately 10-12 weeks of age, although females may have their first estrus as early as 8-9 weeks of age. Group 1 rats serve as control group, while group B and C was treated with 300 and 600 mL kg –1 of T. occidentalis, respectively, for 30 days. Even the proposed new, higher cages will soon have to be replaced by yet higher and larger ones. Throughout the duration of the experiment, the rats were maintained in strict accordance with Canadian Council on Animal Care (CCAC) guidelines. 2. However, national guidelines do not exist for a recommended dose or volume and IP euthanasia has been described as unreliable, with misinjections leading to variable success in ensuring a timely death. cit in CCAC (1091). Enrichment consisted of being placed in a chamber containing various tubes, ladders, and toys for 20 min. Background: The Canadian Council on Animal Care and American Veterinary Medical Association classify intraperitoneal (IP) pentobarbital as an acceptable euthanasia method in rats. The Ethics Committee of Islamic Azad University, Tehran Medical Sciences University (IAUTMU), ap-proved the protocols of this study under the number IR.IAU. ISBN 0309089034.

Following these very restricted lesions, rats were impaired in timing of the intervals. Start studying Ethics Practice Questions. General information; Classification & Labelling & PBT assessment; Manufacture, use & exposure While this is a reality of research, efforts to refine killing methods, to achieve “euthanasia”, for rats and other laboratory animals are ongoing, as reflected in recent updates to the Canadian Council on Animal Care (CCAC) and American Veterinary Medical Association (AVMA) euthanasia guidelines [3, 4]. Intraperitoneal (IP) Injection in Rats and Mice SOP Page 2 of 4 Procedure 1. The reproductive lifespan of rats is on average between 12 and 15 months. the CCAC program are discussed in more detail in following sections. the CCAC has accepted Lawlor's conclusions, the present proposed change in guidelines concerning cage sizes for rats is inadequate. There is no evidence that this has ever occurred or that funding has ever been withheld. To outline available adjuvants and select procedures and techniques recommended by ULAM Veterinary Staff for use in rabbits, rats, and mice. The CCAC guidelines on: euthanasia of animals used in science (CCAC, 2010) will be revised within the next few years, and the matter of carbon dioxide will be revisited at that time.

This Standard Operating Procedure (SOP) describes methods for anesthetizing adult rats and mice. their method of “Euthanasia” is “Cervical Dislocation under anaesthesia”. ----- CCAC guidelines on choosing an appropriate endpoint in experiments using animals for research, teaching and testing They were each (n=6) given twice daily G-Rh2 (10 mg/kg) for 4 doses by subcutaneous (sc) injection. The aim of this study was to expand upon previously published work evaluating the aversiveness of CO2 by introducing an isoflurane treatment group in parallel. A total of 15 wister rats were grouped into 3 groups of 5 animals each. However, there is limited evidence as to when food deprivation compromises animal welfare. These documents, along with their associated FAQs, address conditions normally present in laboratories housing mice and rats, and provide a framework for the implementation of evidence-based practices, with the aim of improving the welfare of mice and rats. 2. Subcutaneous (SC or SQ) Injection in Rats and Mice SOP Purpose This Standard Operating Procedure (SOP) describes the procedure of subcutaneous injections into rats and mice. Keywords: CCAC, Pentobarbital, Killing, Refinement, Welfare Background Over 2 million rats are used in biomedical research in Canada and the European Union annually [1, 2]. Male SD rats (300-350 g) with a carotid artery catheter were purchased from Charles River Laboratories (Wilmington, DE, USA). The rats were fed standard laboratory chow with water ad libitum. This SOP follows the UBC and CCAC guidelines for the collection of blood in laboratory rodents Policy: However, Alberta’s provincial Animal Protection Act makes it mandatory for researchers to comply with CCAC guidelines.
