The two major branches of pharmacology are: pharmacodynamics and pharmacokinetics. Pharmacodynamics - The study of the relationship between concentrations of drug and the biologic effects physiological or biochemical with time. For most drugs it is necessary to know the site of action and mechanism of action at the level of the organ, functional system, or tissue.

Pharmacology intersects with toxicology when the physiological response to a drug is an adverse effect. A poison is any substance, including any drug, that has the capacity to harm a living organism. Poisoning generally implies that damaging physiological effects result from exposure to pharmaceuticals, illicit drugs, or chemicals. Abbreviations ADEs: adverse drug events. ADME: absorption, distribution, metabolism, and elimination.
The latter, of course, has never been a deterrent to this author; and given the ubiquity of these items in professional literature, it would not be surprising for the college to one day inject this topic into a particularly vicious viva station. The relevant material can be found on page 31 of von Zastrow's chapter, which corresponds to page 47 of the pdf. When faced with the need to discuss these curves in some sort of hypothetical viva situation, the CICM exam candidate should avail themselves of a scrap of paper, and reproduce a diagram which, at minimum, should contain the following elements:. To borrow credibility from von Zastrow, it is. All the definitions offered by the major textbooks are much the same. Again, like for all quantal dose-response relationships, many different interpretations are available of what a toxic effect is, and numerous TD 50 s for each drug may be generated.
In toxicology and eco-toxicology, dose descriptor is the term used to identify the relationship between a specific effect of a chemical substance and the dose at which it takes place. The dose descriptors will be used later for deriving the no-effect threshold levels for human health i. They are used for GHS hazard classification and risk assessment. In this article, we will summarize the definition of common toxicology dose descriptors, how they are obtained and what the units are. For inhalation toxicity, air concentrations are used for exposure values. LD50 and LC50 are typically obtained from acute toxicity studies. The units of LD50 and LC50 are listed as follows:.

- Получите удовольствие, профессор. Вы летали когда-нибудь на Лирджете-60. Беккер усмехнулся: - Давненько не летал. Со вчерашнего дня.
Убийцы там уже не. Подъехал полицейский на мотоцикле. Женщина, наклонившаяся над умирающим, очевидно, услышала полицейскую сирену: она нервно оглянулась и потянула тучного господина за рукав, как бы торопя. Оба поспешили уйти. Камера снова показала Танкадо, его руку, упавшую на бездыханную грудь.
