Considering a cholinergic projection from MHb (medial habenula) by retroflexus fasciculus to the IPN (interpeduncular nucleus) would exist. In this regard, the ability for nAChr functional diversity is extensive in the IPN. This implies that presynaptic IPN could modulate the production of acetylcholine within the IPN. Different studies have confirmed that the facilitation of nicotine by presynaptic would agonist the release of acetylcholine out of the IPN. The prime characteristic of this process includes effects of alpha-conotoxins, agonist and agonist investigation, B2 mutation null effects, and the dopamine nAChR mediated release.
Salbutamol could be referred to as am adrenergic agonist receptor, which is used to reduce on the effects of bronchospasm in situations like asthma. It is also used in the treatment of cystic fibrosis, pulmozyme, acetylcysteine, and iprptropium that is linked to DOK-7. As an example of a beta2-agonist, sulbutanol can also be used in obstetrics. The salbutamol that is intravenous could be utilized as a tocolytic in relaxing the smooth muscles of the uterus hence delay premature labor. This has made sulbutamol be the most preferred agent.
In the context of this experiment, Salbutamol antagonist’ caused parallel shift of the given dose response curve. This implies that Salbutamol antagonist’ can elicit a slight and dose-dependent contractile response in the ileum that is induced by acetylcholine. While the Salbutamol agonist’ potentiated the effect of Nicotine and shifted its associated dose response curve towards the left as shown in the graph, it did not affect wholly the contractile effects of the acetylecholyne. This implies that Salbutam agonist as proven by the iochemical studies, tend to act selectively. As far as EC50 of the ...Download file to see next pagesRead More

The effect of Salbutamol on the response of Ileum to Acetylcholine
The effect of Salbutamol on the response of Ileum to Acetylcholine Response to question 1. From the graph, the EC50 of Acetylcholine is 4.00E-08, while the EC50 of Salbutamol + Acetylchline is 4.00E-08. The values for the Ec50 of Nicotine are 5.5E-06, and the EC50 OF Salbutamol + Nicotine is 5.00E-06.

How Drugs and Receptors Interact
Receptors are components of a cell that interact with drugs leading to a myriad of effects of the drug (Arkin and Whitty, 2009, p. 284). There are five primary channels through which a drug can interact with the body. They include ligand-gated ion channels; cytokine receptors; ligand-mediated transmembrane enzymes.

Nicotinic Acetylcholine
As a typical example of the ligand-gated ion channels super family, nicotinic acetylcholine receptor is a member of the Cys-loop family.Cys-loop family includes the 5-hydroxytryptamine type 3 (5-HT3) receptor, -aminobutyric acid type A (GABAA) and GABAC receptors, and glycine (inhibitory) receptors. (Colquhoun 2007) These receptors are ionotropic receptors that form ligand-gated ion channels in the plasma membrane.

Manuscript Introduction and Methods Sections
nAChRs have essential physiological roles in the central and peripheral nervous systems that depend on the subunit composition and are considered to be primary mediators of nicotine addiction (Walsh, H. et al., 2008). An acceptable strategy for pharmacological intervention in nicotine dependence would be the use of a drug with partial agonist properties at nicotinic receptors (Clementi et al., 2000).

Role of the a3b4 nicotinic receptor in drug addiction and in the antiaddictive action of novel ibogaine analogs
While the individual patient, rather than his or her disease, is the appropriate focus of treatment for substance abuse, an understanding of the neurobiology of dependence and addiction can clarify the rationales for treatment methods and goals. Brain abnormalities resulting from chronic use of nicotine, stimulants (e.g., cocaine), opioids, cannabis, alcohol, hallucinogens (e.g., phencyclidine), inhalants (e.g., toluene), and many other abused substances are underlying causes of dependence and addiction meaning intense substance craving and compulsive use.
