Luminol is a chemical compound that exhibits chemiluminescence, emitting a bright blue light when mixed with an appropriate oxidizing agent. It is synthesized through a multi-step process that involves the reaction of 3-nitrophthalic hydrazide with sodium hypochlorite. Luminol's luminescence is enhanced in the presence of a catalyst, often a heavy metal ion such as iron or copper. Its ability to react with bloodstains has made luminol a valuable tool in forensic science for detecting traces of blood at crime scenes. The oxidation of luminol by hydrogen peroxide in the presence of a catalyst produces an excited state of the luminol molecule, which emits light as it returns to its ground state. The blue light emitted by luminol is particularly useful in dark environments. Furthermore, luminol is used in analytical chemistry for detecting trace amounts of various substances, including transition metals and other compounds that can catalyze its oxidation. Luminol research continues to explore its applications in diverse fields, such as biosensing, environmental monitoring, and medical diagnostics. This compound's unique chemiluminescent properties have prompted ongoing investigations into its potential use in various detection methods and analytical techniques.'

Luminol is a prominent chemiluminescent (CL) agent, finding applications across numerous fields, including forensics, immunoassays, and imaging. It is a non-radical-specific amplifying molecule which produces light upon interaction with various reactive oxygen intermediates.
Luminol has been reported to detect myeloperoxidase (MPO) activity in an inflamed area through a light-emitting reaction. It is easy to use and does not pose any health risks, while providing trace evidence for DNA analysis.

Pheochromocytoma, Extra-Adrenal [description not available] | 0 | 2.07 | 1 | 0 |
Pheochromocytoma A usually benign, well-encapsulated, lobular, vascular tumor of chromaffin tissue of the ADRENAL MEDULLA or sympathetic paraganglia. The cardinal symptom, reflecting the increased secretion of EPINEPHRINE and NOREPINEPHRINE, is HYPERTENSION, which may be persistent or intermittent. During severe attacks, there may be HEADACHE; SWEATING, palpitation, apprehension, TREMOR; PALLOR or FLUSHING of the face, NAUSEA and VOMITING, pain in the CHEST and ABDOMEN, and paresthesias of the extremities. The incidence of malignancy is as low as 5% but the pathologic distinction between benign and malignant pheochromocytomas is not clear.

Seizures, Febrile Seizures that occur during a febrile episode. It is a common condition, affecting 2-5% of children aged 3 months to five years. An autosomal dominant pattern of inheritance has been identified in some families. The majority are simple febrile seizures (generally defined as generalized onset, single seizures with a duration of less than 30 minutes). Complex febrile seizures are characterized by focal onset, duration greater than 30 minutes, and/or more than one seizure in a 24 hour period. The likelihood of developing epilepsy (i.e., a nonfebrile seizure disorder) following simple febrile seizures is low. Complex febrile seizures are associated with a moderately increased incidence of epilepsy. (From Menkes, Textbook of Child Neurology, 5th ed, p784) | 0 | 1.95 | 1 | 0 |
