A hydride generation atomic absorption spectrometry method for arsenic determination in biological material was prepared. The samples were digested in muffle furnace at 550oC. The ash was dissolved in 4.5 N hydrochloric acid and the final solution was diluted in 10% hydrochloric acid. The arsenic was determined using a Perkin-Elmer atomic absorption spectrometer equipped with electrodeless disc...

Varivax (varicella virus vaccine live [Oka/Merck]; Merck), a live attenuated varicella vaccine, is indicated for vaccination against varicella in appropriate individuals > or =12 months of age. The 10-year safety profile for Varivax is described using data submitted to Merck from routine global postmarketing surveillance, combined with information from a Varicella Zoster Virus Identification Pr...

Background: Histamine is a food-borne chemical hazard which causes scombroid poisoning. The efficiency of histamine recovery from fish is greatly influenced by selection of an appropriate extraction solvent. Hence, in this study the efficiency of different extraction solvents on recovery of histamine from fresh, frozen and canned fish was evaluated. Methods: Fresh, frozen and canned rainbow tr...

Among the methods available to reduce water production, injecting a gelling system composed of a polymer and a crosslinker has been widely used. In this work, a hydrogel was prepared by crosslinking of an aqueous solution containing hexamethylenetetramine (HMTA) as crosslinker, hydrochloric acid (HCl) as an activator, and the co-polymer of 2-acrylamido-2methyl-propanesulfonic-acid sodium salt (...

OBJECTIVES Hypertonic saline has been proposed to modulate the inflammatory cascade in certain experimental conditions, including pulmonary inflammation caused by inhaled gastric contents. The present study aimed to assess the potential anti-inflammatory effects of administering a single intravenous dose of 7.5% hypertonic saline in an experimental model of acute lung injury induced by hydrochl...

On October 21, 1987, Merck & Co., Inc., announced plans to donate Mectizan (ivermectin), a new medicine designed to combat onchocerciasis (Ôriver blindnessÕ), for as long as it might be needed. Merck took this action, working in col laboration with international experts in parasitology, the World Health Organization, and other agencies to reach those affected by the illness. This unusual decisi...
