oxotremorine profile

Oxotremorine is a synthetic cholinergic agonist that acts primarily on the muscarinic acetylcholine receptors. It is known for its potent tremor-inducing properties in animals and humans, hence its name. It was initially synthesized in the 1950s as a potential therapeutic agent for Parkinson's disease but was found to have limited clinical value. However, it has become a valuable tool for research into the cholinergic system, particularly in understanding the role of muscarinic receptors in various physiological processes, including learning, memory, and movement. The compound's effects are attributed to its ability to mimic the actions of acetylcholine at muscarinic receptors, leading to a range of physiological responses, including increased salivation, bronchoconstriction, and gastrointestinal motility. Its tremor-inducing effects, along with its ability to affect other physiological functions, make it a valuable research tool for studying the cholinergic system and developing new therapeutic approaches for a range of disorders.'

Aganglionic Megacolon [description not available]	2.37	2	0
Esophageal Achalasia A motility disorder of the ESOPHAGUS in which the LOWER ESOPHAGEAL SPHINCTER (near the CARDIA) fails to relax resulting in functional obstruction of the esophagus, and DYSPHAGIA. Achalasia is characterized by a grossly contorted and dilated esophagus (megaesophagus).	1.97	1	0

Blood Pressure, Low [description not available]	1.97	1	0

Mood Disorders Those disorders that have a disturbance in mood as their predominant feature.	1.97	1	0
Cardiac Failure [description not available]	1.97	1	0
Heart Failure A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.	1.97	1	0

Cancer of Parathyroid [description not available]	1.97	1	0
Adenoma A benign epithelial tumor with a glandular organization.	1.97	1	0
Hyperplasia An increase in the number of cells in a tissue or organ without tumor formation. It differs from HYPERTROPHY, which is an increase in bulk without an increase in the number of cells.	1.97	1	0
Parathyroid Neoplasms Tumors or cancer of the PARATHYROID GLANDS.	1.97	1	0
Basal Ganglia Diseases Diseases of the BASAL GANGLIA including the PUTAMEN; GLOBUS PALLIDUS; claustrum; AMYGDALA; and CAUDATE NUCLEUS. DYSKINESIAS (most notably involuntary movements and alterations of the rate of movement) represent the primary clinical manifestations of these disorders. Common etiologies include CEREBROVASCULAR DISORDERS; NEURODEGENERATIVE DISEASES; and CRANIOCEREBRAL TRAUMA.	1.97	1	0
Muscle Spasm [description not available]	2.36	2	0
Spasm An involuntary contraction of a muscle or group of muscles. Spasms may involve SKELETAL MUSCLE or SMOOTH MUSCLE.	2.36	2	0

Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).	1.96	1	0
