Acute toxicity

population (group A) that is exposed to inhaling more than 1 ppm of vinyl chloride in an eight- hour shift, as compared to another group of population (group B) exposed to a lower air concentration in the same amount of time, develops a severe or acute reaction. Specificity explains that if both groups were exposed to the exact strength of air concentration in the same amount of time (eight hours), and only group A develops a reaction, that certain people are more prone to quickly react to…

Abstract A Friedal-Craft reaction was performed to synthesize 1,4-di-t-butyl-2,5-dimethoxy-benzene from p-dimethoxybenzene and t-butyl alcohol. The product of the reaction was filtered using a Hirsch funnel, before recrystallizing and filtering a second time. The recorded mass of the product was .08g and the melting point was 47-52.7 °C. Introduction1 This experiment was designed to practice working with electrophilic aromatic substitution reactions. Specifically, a Friedel-Craft reaction was…

Adverse events were found at doses of 200 and 1000 mg/kg/day.3 In rabbits with pregnancy, Daklinza was administered orally at doses of 0, 40, 200, or 750 mg/kg/day.3 Maternal toxicity was observed at doses of 200 and 750 mg/kg/day. The AUC value was 22 fold higher than the recommended human dose at a dose of 40…

considered lent virus genus. The pathophysiology of HIV creates innumerable cellular immune insufficiencies that are categorized by the weakening of helper T lymphocytes (CD4+ cells). The loss of CD4+ cells results in the maturity of unscrupulous toxicities and neoplastic processes (Bennett,…

Vivisection: Necessity or Brutality? Introduction/Explanation of Issues From the ancient times of the Greek and Romans to modern society, experimenting on living organisms is a concept yet to be outdated. Rather than testing on people, animals have become the primary subjects who endeavor rigorous scientific experimenting; ultimately because it is inhumane to test on a person with such serve trials. Vivisectionists, scientists who conduct experimental trials on living creatures, defend their…

excreting by kidney. Millions of people suffer from this kind of arthritis with an attack of sudden burning pain, stiffness, and swelling in a joint(usually a big toe). However, the current treatment for gout is far from adequate, because controlling the acute episode has been the prior management for decades by using nonsteroidal antinflammatory drugs (NSAIDs), colchicine or glucocorticoids. With a deeper understanding of gout pathophysiology these years, urate lowing has…

Chapter 1 THE PROBLEM AND ITS SCOPE Introduction Hyperlipidemia is not new to Filipinos. Hyperlipidemia is the abnormal elevation of any lipids like cholesterol and triglycerides in the blood (Saunders, 2007). According to the 2008 National Nutrition Survey (NSS) conducted by Food and Nutrition Research Institute of the Department of Science and Technology (FNRI-DOST) the total cholesterol level among Filipino adults increases to 10.2 (mg/dL) from the 2003 survey result 8.5 (mg/dL).…

: Origanum majorana L. widely used in Jordan and other Mediterranean countries as a flavoring and herbal spice. An infusion of the plant is used for treatment of internal diseases, haemorrhoids, pains, and animal bites and poisons. In this study, I attempted to identify the possible antinociceptive action of Origanum majorana methanol leaf extract using tail immersion, hot plate, and writhing tests. The antinociceptive effect of the methanol extract of Origanum majorana (MEO) leaves was…

Chapter 01: Introduction 1.1. Xenobiotics The term xenobiotic is derived from Greek words, “xenos”, meaning strange or foreign, and “bios”, meaning life. Thus xenobiotics are exogenous chemicals which includes natural and synthetic chemicals. These can be pesticides, chemical vapors from automobiles, industrial chemicals, plastics, secondary plant metabolites, toxins produced by plants, molds and animals, food additives etc. Xenobiotics are considered as pollutants, but all the pollutants are…
