Predictive toxicology Predictive toxicology studies about the potential and actual risks of chemicals /drugs purchase 60 pills abana visa cholesterol from shrimp. Based on specific socio-medical issues A) Occupational toxicology Occupational toxicology Deals with chemical found in the workplace E buy abana 60 pills with amex cholesterol from shrimp is it good. B) Environmental toxicology Environmental toxicology deals with the potentially deleterious impact of chemicals, present as pollutants of the environment, to living organisms. It is concerned with the toxic effects of chemical and physical agents on living organisms, especially in populations and communities with defined ecosystems. C) Clinical toxicology Clinical toxicology deals with diagnosis and treatment of the normal diseases or effects caused by toxic substances of exogenous origin i. D) Forensic toxicology Forensic toxicology closely related to clinical toxicology. It deals with the medical and legal aspects of the harmful effects of chemicals on man, often in post mortem material, for instance, where there is a suspicion of murder, attempted murder or suicide by poisoning. Toxicokinetics and Toxicodynamics - Toxicokinetics deals with absorption, distribution, biotransformation (biotransformation) and excretion of chemicals. Toxicokinetics i) Absorption Absorption is the process by which the chemical enters the body. It depends on the route of administration, dissociation (to become ionized), dissolution (ability of solid dosage form to become soluble), concentration, blood flow to the site, and the area of the absorptive site. Bioavailability is the fraction of unchanged drug reaching the systemic circulation following of non-vascular administration. Volume of distribution (Vd) is calculated from the dose taken and the resulting plasma concentration: Vd = dose /plasma concentration The importance of volume of distribution in toxicology is - Predicting peak blood concentration of the chemical taken - Calculating the amount of substance in the body to verify the quantity ingested - Deciding whether to apply systemic toxin elimination techniques Factors determining the rate of distribution of chemicals in the body are - Protein binding – chemicals highly bound to protein have small volume of distribution - Plasma concentration – when the volume of distribution of chemicals is small, most of the chemical remains in the plasma - Physiological barriers – chemicals will not uniformly distributed to the body due to specialized barriers e. It is a process by which the body transforms a chemical and makes it more water soluble so the chemical can be eliminated more rapidly via the kidney into the urine. Biotransformation can produce metabolites that are pharmacologically active and toxic E. Liver is the major site of biotransformation for many chemicals & other organs that are involved are lungs, kidneys, skin &so on. Interactions during biotransformation includes There are two phases of biotransformation Phase I – the drug is converted into more polar compound e. Half life (t ½) –is the time required to reduce the blood concentration of the chemical to half. Excretion through the lungs is the major route for gaseous substances; and in the case of non-volatile water – soluble drugs, the kidneys are the most important routes of excretion. Additional routes include sweat, saliva, tears, nasal secretions, milk, bile and feces. It is a quantitative measure of the volume of blood cleared of drug per unit time, usually expressed in milliliter pe4r minute. B - Certain points regarding the toxicokinetics of toxic agents;  Drug absorption after a toxic ingestion may be delayed and prolonged;  The half-life and total body clearance are often lengthened;  Liver-metabolizing enzymes may become saturated, slowing hepatic elimination; 12 Toxicology  Chemicals with large volumes of distribution are often highly tissue-bound and measures to enhance their elimination are not effective;  Poor perfusion of the liver and kidneys secondary to the toxic effects of the substance may slow clearance. Toxicodynamics Toxicodynamics is the mechanism of action of a toxic chemical to the body (what chemicals do to the body). We have two types of responses so called Quantal dose response (all- or – none response) & graded dose response (when dose increases, the response increases in graded fashion). Comparison of dose –response curves for efficacy (A), toxicity (B), & lethality (C). The effective,toxic, &lethal dosage for 50% of the population in the groupcan be estimated as shown. Common effects of chemicals to cause symptoms Chemicals can cause symptoms through the following mechanisms a.

The Hb and red blood cell production in the body is under control of erythropoietin buy abana 60pills without a prescription exogenous cholesterol definition, which is produced by the kidneys cheap abana 60pills with mastercard cholesterol levels uk vs usa. Its production is stimulated when the amount of oxygen delivered to the kidneys is lower than normal. Normally Hb concentration in men is higher then women, because the red cell production is also stimulated by androgen. The oxygen saturation of Hb O2 combined with Hb / O2 capacity One gram of Hb can combine with 1. Because the reduced Hb is purple a low arterial oxygen saturation causes cyanosis. When the concentrations of the products of the carbonic acid dissociation reaction bicarbonate diffuses into the blood but not hydrogen ion because the red cell membrane is relatively impermeable to the positively charged ions. In order to maintain - electrical neutrality Cl ions diffuse into the red cells according to the Gibbs-Donnan equilibrium + (chloride shift). Common reasons are excessive ingestion of alkalis and loss of gastric acid due to vomiting. This increase in ventilation (hyperpnea) matches the simultaneous increase in oxygen consumption and carbon dioxide production that the arterial blood carbon dioxide and oxygen partial pressures and pH do not change dramatically (Please note that hyperpnea is different from hyperventilation. The mechanism underlying the exercise-induced changes in ventilation is not clear. Neurogenic mechanisms: (1) stimulation of respiratory system muscles by sensory nerve activity from exercising limbs, probably via activating brain stem respiratory centres and/or via spinal reflexes. Chemical mechanisms: Because partial pressures of carbon dioxide and oxygen do not change during exercise it is difficult to explain possible chemical factors. However, the focal changes in these parameters near chemoreceptor area may contribute to the exercise-induced changes in ventilation. Anaerobic threshold: The maximum rate of oxygen consumption than can be attained before blood lactic acid levels rise as a result of anaerobic respiration. Lactic acid concentration is increased due to anaerobic limitations in the muscle cells during heavy exercise. Hypoxic ventilatory response: Hyperventilation induced by the decreased partial oxygen pressure. This lowers the arterial partial carbon dioxide pressure and causes respiratory alkalosis. The rise in blood pH in turn set the ventilation to a more stable but still slightly higher levels. Hyperventilation increases the tidal volume and reduces the proportion of the anatomical death space in the inspired air. However, in spite of all these adaptation mechanisms, the partial oxygen pressure in the arterial blood can not be increased more than the partial oxygen pressure in the inspired air. As a result partial pressure of oxygen in the arterial blood decreases with increasing altitude. At sea levels arterial blood loses 22% of its oxygen load in tissues: The oxygen saturation of the arterial and venous blood is 97% and 75%, respectively. However, at very high altitudes increase in blood pH causes a shift to the left in the oxygen saturation curve and increases the affinity of Hb to oxygen. This second step is indeed beneficial at very high altitude by increasing the oxygenation of the blood in the lungs.
