Hyaluronic acid, or HA, is a naturally occurring polymer found in every tissue of At this time, there are no known adverse reactions when taken in conjunction the body. It is particularly concentrated in the skin (almost 50% of all HA in the with medications. body is found in the skin) and synovial fluid. It is composed of alternating units of n-acetyl-d-glucosamine and d-glucuronate. This polymer’s functions include Hyaluronic acid attracting and retaining water in the extracellular matrix of tissues, in layers of skin, and in synovial fluid.* each vegetarian capsule contains v 3 hyaluronic acid (low molecular weight) ..............................................................................70 mg Features Include other ingredients: hypo-allergenic plant fiber (cellulose), vegetarian capsule (cellulose, water) 1–2 capsules per day, in divided doses, with or between meals.

Prohibited and Restricted Chemical List
School Emergency Response Plan and Management Guide Prohibited and Restricted Chemical List PROHIBITED AND RESTRICTED CHEMICAL LIST Introduction After incidents of laboratory chemical contamination at several schools, DCPS, The American Association for the Advancement of Science (AAAS) and DC Fire and Emergency Management Services developed an aggressive program for chemical control to eliminate student and staff exposure to potential hazardous chemicals. Based upon this program, all principals are required to conduct a complete yearly inventory of all chemicals located at each school building to identify for the removal and disposal of any prohibited/banned chemicals. Prohibited chemicals are those that pose an inherent, immediate, and potentially life- threatening risk, injury, or impairment due to toxicity or other chemical properties to students, staff, or other occupants of the school. These chemicals are prohibited from use and/or storage at the school, and the school is prohibited from purchasing or accepting donations of such chemicals. Restricted chemicals are chemicals that are restricted by use and/or quantities. If restricted chemicals are present at the school, each storage location must be addressed in the school's written emergency plan. Also, plan maps must clearly denote the storage locations of these chemicals. Restricted chemicals—demonstration use only are a subclass in the Restricted chemicals list that are limited to instructor demonstration. Students may not participate in handling or preparation of restricted chemicals as part of a demonstration. If Restricted chemicals—demonstration use only are present at the school, each storage location must be addressed in the school's written emergency plan. Section 7: Appendices – October 2009 37 School Emergency Response Plan and Management Guide Prohibited and Restricted Chemical List Following is a table of chemicals that are Prohibited—banned, Restricted—academic curriculum use, and Restricted—demonstration use only. -

Effect of L-Canavanine, an Inhibitor of Inducible Nitric Oxide Synthase, on Myocardial Dysfunction During Septic Shock
J Nippon Med Sch 2002; 69(1) 13 ―Original― Effect of L-canavanine, an Inhibitor of Inducible Nitric Oxide Synthase, on Myocardial Dysfunction During Septic Shock Norihito Suzuki, Atsuhiro Sakamoto and Ryo Ogawa Department of Anesthesiology, Nippon Medical School Abstract Overproduction of nitric oxide(NO)by inducible NO synthase(iNOS)plays aroleinthe pathophysiology of septic shock. The depression of cardiac contractilityinsuchsituationsis mediated by proinflammatory cytokines, including interleukin-1β(IL-1β), and tumor necrosis factor-α(TNF-α). The effects of two NOS inhibitors with different isoform selectivity were compared in isolated working rat hearts. The depression of contractility by IL-1β and TNF-α was prevented by administration of a nonselective nitric oxide synthase inhibitor, NG-nitro-L- arginine methyl ester(L-NAME)or an inhibitor of inducible nitric oxide synthase, L-canavanine. In contrast, when L-NAME was administered in the absence of IL-1β and TNF-α, it depressed contractility over the 2h perfusion period by significantly reducing coronary flow. These results support current thinking that the depression of myocardial functionbyIL-1β and TNF-α is mediated, at least in part, by an intracardiac increase in inducible nitric oxide synthase, and that in contrast to L-NAME, the decline in coronary conductance seen in cytokine-treated is not prevented by L-canavanine hearts. L-canavanine shows selective inhibition of inducible nitric oxide synthase unlike the vasopressor action of L-NAME in cytokine-treated hearts. (J Nippon Med Sch 2002; 69: 13―18) Key words: nitric oxide(NO), nitric oxide(NO)synthase, working heart, L-canavanine, NG-nitro-L-arginine methyl ester(L-NAME) We have previously demonstrated that admini- Introduction stration of L-canavanine or L-NAME attenuated the endotoxin-induced hypotension and vascular hypore- Nitric oxide(NO)may be produced within the activity to adrenaline, and the beneficial hemody- heart by either constitutive or inducible NO1,2. -
