Chemistry, Biochemistry and Pharmacology of Hydrogen Sulfide by Philip K. Moore,Matt Whiteman Pdf
This book puts hydrogen sulfide in context with other gaseous mediators such as nitric oxide and carbon monoxide, reviews the available mechanisms for its biosynthesis and describes its physiological and pathophysiological roles in a wide variety of disease states. Hydrogen sulfide has recently been discovered to be a naturally occurring gaseous mediator in the body. Over a relatively short period of time this evanescent gas has been revealed to play key roles in a range of physiological processes including control of blood vessel caliber and hence blood pressure and in the regulation of nerve function both in the brain and the periphery. Disorders concerning the biosynthesis or activity of hydrogen sulfide may also predispose the body to disease states such as inflammation, cardiovascular and neurological disorders. Interest in this novel gas has been high in recent years and many research groups worldwide have described its individual biological effects. Moreover, medicinal chemists are beginning to synthesize novel organic molecules that release this gas at defined rates with a view to exploiting these new compounds for therapeutic benefit.
Vascular Effects of Hydrogen Sulfide by Jerzy Bełtowski Pdf
This book explores techniques for exploring hydrogen sulfide (H2S) and its effects on the vascular system through numerous experimental animal models and vascular preparations. Alterations of vascular H2S generation/signaling may be involved in the pathogenesis of systemic and pulmonary arterial hypertension, ischemic heart disease, ischemic stroke, preeclampsia, and erectile dysfunction, and H2S also serves as an attractive target for pharmacotherapy of cardiovascular diseases, as well as possible effects on cancer, wound healing, and diabetic retinopathy, among other pathologies. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Vascular Effects of Hydrogen Sulfide: Methods and Protocols is an ideal aid for scientists working to extend our knowledge in this valuable and wide-ranging field of study.

Review of Submarine Escape Action Levels for Selected Chemicals by National Research Council,Division on Earth and Life Studies,Board on Environmental Studies and Toxicology,Committee on Toxicology,Subcommittee on Submarine Escape Action Levels Pdf
On-board fires can occur on submarines after events such as collision or explosion. These fires expose crew members to toxic concentrations of combustion products such as ammonia, carbon monoxide, hydrogen chloride, and hydrogen sulfide. Exposure to these substances at high concentrations may cause toxic effects to the respiratory and central nervous system; leading possible to death. T protect crew members on disabled submarines, scientists at the U.S. Navy Health Research Center's Toxicology Detachment have proposed two exposure levels, called submarine escape action level (SEAL) 1 and SEAL 2, for each substance. SEAL 1 is the maximum concentration of a gas in a disabled submarine below which healthy submariners can be exposed for up to 10 days without encountering irreversible health effects while SEAL 2 the maximum concentration of a gas in below which healthy submariners can be exposed for up to 24 hours without experiencing irreversible health effects. SEAL 1 and SEAL 2 will not impair the functions of the respiratory system and central nervous system to the extent of impairing the ability of crew members in a disabled submarine to escape, be rescued, or perform specific tasks. Hoping to better protect the safety of submariners, the chief of the Bureau of Medicine and Surgery requested that the National Research Council (NRC) review the available toxicologic and epidemiologic data on eight gases that are likely to be produced in a disabled submarine and to evaluate independently the scientific validity of the Navy's proposed SEALs for those gases. The NRC assigned the task to the Committee on Toxicology's (COT's) Subcommittee on Submarine Escape Action Levels. The specific task of the subcommittee was to review the toxicologic, epidemiologic, and related data on ammonia, carbon monoxide, chlorine, hydrogen chloride, hydrogen cyanide, hydrogen sulfide, nitrogen dioxide, and sulfur dioxide in order to validate the Navy's proposed SEALs. The subcommittee also considered the implications of exposures at hyperbaric conditions and potential interactions between the eight gases. Review of Submarine Escape Action Levels for Selected Chemicals presents the subcommittee's findings after evaluation human data from experimental, occupational, and epidemiologic studies; data from accident reports; and experimental-animal data. The evaluations focused primarily on high-concentration inhalation exposure studies. The subcommittee's recommended SEALs are based solely on scientific data relevant to health effects. The report includes the recommendations for each gas as determined by the subcommittee as well as the Navy's original instructions for these substances.
Sudden death among sewage workers is the most familiar form of hydrogen sulphide poisoning. This colorless, flammable gas has a characteristic odor of rotten eggs. It is produced naturally and as a result of human activity. Natural sources include nonspecific and anaerobic bacterial reduction of sulphates and sulphur-containing organic compounds. Hydrogen sulphide is found naturally in crude petroleum, natural gas, volcanic gases, and hot springs. It is also found in ground water. It is released from stagnant or polluted waters and manure or coal pits. In the industry, it is used as an intermediate in the manufacture of sulphuric acid and inorganic sulphides and as an agricultural disinfectant.--Publisher's description.
