Lidocaine is an antiarrhythmic medication of the class Ib type. [7] This means it works by blocking sodium channels thus decreasing the rate of contractions of the heart. [10] [7] When injected near nerves, the nerves cannot conduct signals to or from the brain. [8] Lidocaine was discovered in 1946 and went on sale in 1948. [11]
A sundew with a leaf bent around a fly trapped by mucilage. Mucilage is a thick gluey substance produced by nearly all plants and some microorganisms.These microorganisms include protists which use it for their locomotion, with the direction of their movement always opposite to that of the secretion of mucilage.

Veratridine is a steroidal alkaloid found in plants of the lily family, specifically the genera Veratrum and Schoenocaulon. [1] Upon absorption through the skin or mucous membranes, it acts as a neurotoxin by binding to and preventing the inactivation of voltage-gated sodium ion channels in heart, nerve, and skeletal muscle cell membranes.

The GI cocktail is a mixture of a viscous anesthetic, an antacid, and an anticholinergic. [1] [2] Common viscous anesthetics use are viscous lidocaine or xylocaine.Common antacids used are magnesium hydroxide, aluminum hydroxide, or simethicone (more commonly known as Mylanta or Maalox). [3]
Substances may be excreted to the surface of the plant or into intercellular cavities or canals. Some of the many substances contained in the secretions are not further utilized by the plant (resins, rubber, tannins, and various crystals), while others take part in the functions of the plant (enzymes and hormones).
Plant communication encompasses communication using volatile organic compounds, electrical signaling, and common mycorrhizal networks between plants and a host of other organisms such as soil microbes, [2] other plants [3] (of the same or other species), animals, [4] insects, [5] and fungi. [6]
It is a colorless viscous liquid. Commercially significant derivatives are the anesthetics lidocaine, bupivacaine, mepivacaine, and etidocaine. [1]
Hypersensitive response (HR) is a mechanism used by plants to prevent the spread of infection by microbial pathogens.HR is characterized by the rapid death of cells in the local region surrounding an infection and it serves to restrict the growth and spread of pathogens to other parts of the plant.
