• Lack of Self Administration of Cocaine in Dopamine D1

  Nov 28 2007  Evidence suggests a critical role for dopamine in the reinforcing effects of cocaine in rats and primates. However self administration has been less often studied in the mouse species and to date knock out of individual dopamine related genes in mice has not been reported to reduce the reinforcing effects of cocaine. We studied the dopamine D1 receptor

  Guidelines for Blood Collection in Mice and Rats

  Can be used in both rats and mice by clipping e.g. amputating no more than 1mm of the distal tail in mice or 2 mm in rats. Produces a sample of variable quality that may be contaminated with tissue products. Sample quality decreases with prolonged bleeding times and milking of the tail. Repeated collections possible.

  Jul 05 2021  An IV infusion is a controlled administration of medication into your bloodstream over time. The two main methods of IV infusion use either gravity or a pump to send medication into your catheter

• Self Administration Systems in Rodents SAI Infusion

  Self administration a form of operant conditioning often provides the reward as an intravenous dose of drug. Both the test agent and the addictive drug can be administered remotely through chronically implanted intravenous catheters using swivel and tether systems. Standard self administration systems use threaded c

• How to achieve chronic intravenous drug self

  Mar 01 2006  The total number of articles on intravenous drug self administration in which rats or monkeys served as subjects is approximately 1200 and 560 respectively. Mice have been used for the same purpose in approximately only 80 studies to date as of January 2005 .

• Intravenous administration of DPSCs and BDNF improves

  Feb 28 2018  Additionally we investigated whether intravenous administration of rat derived DPSCs enhanced neurological outcomes after ischemic stroke. We demonstrated that BDNF combined with DPSCs increased the viability of transplanted cells facilitated the differentiation and neuroprotective effects compared with DPSCs or BDNF alone.

  The athymic nude rat rnu/rnu has been used for a number of years in research into various human tumours involving xenotransplantation. We now report the validation of a continuous intravenous infusion method in nude rats using a tail cuff tether which enables the study of the efficacy of novel anti cancer materials in this mutant strain using intravenous infusion and

• Compound Administration IV

  Generally a 27 30 gauge needle is used for this injection and maximum volume of administration is 100 and 300 microliters for mice and rats respectively. For intravenous injection via the retro orbital route one should have a fair understanding of the orbital venous structure.

• Role of Dopamine D2 like Receptors in Cocaine Self

  Apr 01 2002  Moreover in intact rats a D2 antagonist increased rates of high dose cocaine self administration whereas D3 and D4 antagonists were ineffective. These results suggest that the D2 receptor but not D3 or D4 receptors is involved in the mechanisms that serve to limit rates of high dose cocaine self administration in mice and rats.
