CNS depression

The aim of this study was to evaluate in an avian species the influence of isoflurane and sevoflurane on BIS, each at different minimum anaesthetic concentrations (MAC) multiples, alone or combined with butorphanol or medetomidine.

Regulator of G protein signaling (RGS) proteins are gatekeepers regulating the cellular responses induced by G protein-coupled receptor (GPCR)-mediated activation of heterotrimeric G proteins. Specifically, RGS proteins determine the magnitude and duration of GPCR signaling by acting as a GTPase-activating protein for Gα subunits, an activity facilitated by their semiconserved RGS domain. The R7 subfamily of RGS proteins is distinguished by two unique domains, DEP/DHEX and GGL, which mediate membrane targeting and stability of these proteins.

Drugs that act upon the central nervous system (CNS) influence the lives of everyone, every day. These agents are invaluable therapeutically because they can produce specific physiological and psychological effects. Without general anesthetics, modern surgery would be impossible. Drugs that affect the CNS can selectively relieve pain, reduce fever, suppress disordered movement, induce sleep or arousal, reduce the desire to eat, or allay the tendency to vomit. Selectively acting drugs can be used to treat anxiety, mania, depression, or schizophrenia and do so without altering consciousness....

Local Anesthetics circulation would lead to unwanted systemic reactions such as: ¼ blockade of inhibitory CNS neurons, manifested by restlessness and seizures (countermeasure: injection of a benzodiazepine, p. 226); general paralysis with respiratory arrest after higher concentrations. ¼ blockade of cardiac impulse conduction, as evidenced by impaired AV conduction or cardiac arrest (countermeasure: injection of epinephrine). Depression of excitatory processes in the heart, while undesired during local anesthesia, can be put to therapeutic use in cardiac arrhythmias (p. 134).

B12a; exchange of -CN for -OH group). Adverse effects, in the form of hypersensitivity reactions, are very rare. Folic Acid (B). Leafy vegetables and liver are rich in folic acid (FA). The minimal requirement is approx. 50 µg/d. Polyglutamine-FA in food is hydrolyzed to monoglutamine-FA prior to being absorbed. FA is heat labile. Causes of deficiency include: insufficient intake, malabsorption in gastrointestinal diseases, increased requirements during pregnancy.
