Synergistic Effect of Intracranial and Intraperitoneal Delivery of Analgesic Drugs on Thermal Pain Response in a Rat02:25

Synergistic Effect of Intracranial and Intraperitoneal Delivery of Analgesic Drugs on Thermal Pain Response in a Rat

454
Source: Martinez, E., et al. Intracranial Pharmacotherapy and Pain Assays in Rodents. J. Vis. Exp. (2019).This video demonstrates the intracranial administration of an analgesic drug in an anesthetized rat with a pre-implanted guide cannula in the prefrontal cortex. An additional analgesic drug is co-administered intraperitoneally. Following recovery, the rat’s thermal pain response is assessed using Hargreave’s apparatus, where paw withdrawal latency is measured to evaluate the...

Electrochemistry is the science involved in the interconversion of electrical and chemical reactions. Such reactions are called reduction-oxidation, or redox reactions. These important reactions are defined by changes in oxidation states for one or more reactant elements and include a subset of reactions involving the transfer of electrons between reactant species. Electrochemistry as a field has evolved to yield sufficient insights on the fundamental principles of redox chemistry and multiple...

Redox Reactions

Oxidation-reduction or redox reactions involve the transfer of electrons from one molecule or atom to another. When an atom gains an electron, another atom must lose an electron, meaning oxidation and reduction must occur together. Since the redox occurs in pairs, the atom that gets oxidized is also called the reducing agent or reductant, and the atom that is reduced is also called the oxidizing agent or oxidant. A straightforward way to remember the definitions of oxidation and reduction is...

Oxidation and Reduction
Some chemical reactions can be classified as reduction-oxidation reactions, or redox reactions. Oxidation is the process of matter, like an atom or ionic molecule, losing one or more electrons, and reduction is the process of the matter gaining one or more electrons.
Oxidation States
Each atom in a molecule has its own oxidation state or oxidation number. The oxidation state describes how oxidized a molecule is relative to its free elemental form. The oxidation state is...
