Book excerpt: Excerpt from The American Encyclopedia and Dictionary of Ophthalmology, Vol. 4: Cocaine to Conjunctivitis Phlyctenulosa Miliaris Cocaine. Erythroxyline. Methyl-benzoyl-ecgonine. This agent, so extremely important from the standpoint of the Ophthalmic surgeon, is derived from the leaves of erythroxylum coca, with the formula c17h21n04. It is the best known and one of. The most useful local anesthetics we possess. This alkaloid is present in coca to the extent of about one-half of one per cent. And occurs in the shape of colorless prisms, soluble in 600 parts of water, five of alcohol, twelve of olive oil; insoluble in lard and vaselin. The hydrochloride is its best known salt, although the benzoate, borate, citrate, hydrobromide, hydriodide, lactate, nitrate, tartrate, salicylate, phenate, oleate, stearate (best for ointments), and sulphate are well known. The National For mulary recommends cocaine borate instead of the hydrochloride in solutions intended for ocular use on account of its greater stability. The most frequently used incompatibilities with cocaine and its salts are its combination in solution with zinc sulphate and sodium borate, both of which precipitate it. As the hydrochloride is incompatible with silver salts cocaine nitrate should be used in lieu of the hydrochloride when argentic compounds are prescribed with it. In the usual dosage, 3 to 5 per cent., it dilates the pupil moderately, is a feeble cycloplegic, produces anemia of the conjunctiva and is a dangerous poison. The drug greatly increases the action of other alkaloids with which it is instilled into the conjunctival sac, probably because its desiccating and loosening action on the anterior corneal epithelium enables the solution to reach more easily the substantia propria. The eyes should always be kept closed during the first stages of cocain instillation as this largely neutralizes the hurtful action of the drug on the cornea. Michel goes even further than this in claiming that the exfoliation of the pavement epithelium may be so marked as to justify calling the condition cocain keratitis and advises one to cover the eye with a moist compress when strong solutions are used or the drug applied for any length of time. It is claimed that this agent may precipitate an attack of glaucoma, while even from simple instillations into the eye of a comparatively weak solution toxic symptoms (vertigo, pallor of the face, fainting, thick speech, weak pulse, loss of consciousness, occasionally silow themselves, requiring alcoholics, amyl nitrite inhalations and other stimulation for their relief.

Available in PDF, EPUB and Kindle. Book excerpt: Alphaherpesviruses are a fascinating group of DNA viruses that includes important human pathogens such as herpes simplex virus type 1 (HSV-1), HSV-2, and varicella-zoster virus (VZV): the causative agents of cold sores, genital ulcerous disease, and chickenpox/shingles, respectively. A key attribute of these viruses is their ability to establish lifelong latent infection in the peripheral nervous system of the host. Such persistence requires subversion of the host's immune system and intrinsic antiviral defense mechanisms. Understanding the mechanisms of the immune evasion and what triggers viral reactivation is a major challenge for today's researchers. This has prompted enormous research efforts into understanding the molecular and cellular biology of these viruses. This up-to-date and comprehensive volume aims to distill the most important research in this area providing a timely overview of the field. Topics covered include: transcriptional regulation, DNA replication, translational control, virus entry and capsid assembly, the role of microRNAs in infection and oncolytic vectors for cancer therapy. In addition there is coverage of virus-host interactions, including apoptosis, subversion of host protein quality control and DNA damage response pathways, autophagy, establishment and reactivation from latency, interferon responses, immunity and vaccine development. Essential reading for everyone working with alphaherpesviruses and of interest to all virologists working on latent infections.
