CASE 1-5 Flashcards
Pharmacology
(CASE 1 - SBA)
Define - Clearance (Cl)
the volume of plasma that has been cleared of drug (removed from) per unit time
Pharmacology
(CASE 1 - SBA)
Define - Half-life (t1/2
the length of time it takes for the plasma concentration of a drug to half
Pharmacology
(CASE 1 - SBA)
Define - volume of distribution (Vd)
• is the distribution of a drug between the plasma and the rest of the body after dosing Dependent on - • drug permeability across membranes • binding within compartments •pH partition
Physiology
(CASE 1 - SBA)
Define - acute inflammation
is a short-term process occurring in response to tissue injury and usually appears within mins-hours - cardinal signs - pain, redness, swelling, heat, and loss of function
Physiology
(CASE 1 - SBA)
Define - chronic inflammation
is a prolonged inflammatory response that insoles a progressive change in the type of cells present at the site of inflammation - and characterised by destruction and repair of the tissue
Pathology
(CASE 1 - SBA)
Define - atheroma
is a progressive disease characterised by the accumulation of lipids and fibrous element in the large arteries
Pathology
(CASE 1 - SBA)
Define - thrombosis
blood clot in situ in the vessels
Pathology
(CASE 1 - SBA)
Define - embolism
blood clot (or fat/air) carried around blood system which becomes lodged and causes a blockage (embolism)
Public Health
(CASE 1 - SBA)
Define - Epidemiology
is the study and analysis of the distribution, patterns and determinants of health and disease conditions in defined populations
Public Health
(CASE 1 - SBA)
Define - mortality rates
the number of deaths in a certain group of people in a certain period of time
Public Health
(CASE 1 - SBA)
Define - incidence rates
- the rate of newly diagnosed cases of a disease or illness
* the number of new cases reported in a certain period of time
Public Health
(CASE 1 - SBA)
Define - prevalence rates
is the number of individuals with the disease either at a specific point in time (the point prevalence) or over a specified time period (the period prevalence)
Pathology
(CASE 2 - SBA)
Define - ischaemia
an in adequate supply of blood to a tissue resulting in an insufficient supply of oxygen and other metabolic needs for that tissue
Pathology
(CASE 2 - SBA)
Define - infarction
an insufficient supply of blood carrying oxygen and other metabolic needs leading to cell or tissue necrosis – death
Cell Biology
(CASE 2 - SBA)
Define - Dystrophic calcification
calcification that occurs in degenerated or necrotic tissue
Cell Biology
(CASE 2 - SBA)
Define - Metastatic calcification
occurs when calcium salts are precipitated in normal tissue as a result of high serum calcium or phosphate levels
Cell Biology
(CASE 2 - SBA)
Define - necrosis
pathological cellular/tissue death in a living organism irrespective of cause and an inflammatory response
Cell Biology
(CASE 2 - SBA)
Define - apoptosis
normal or pathological individual cell death (programmed) and characterised by activation of endogenous proteases and endonucleases - NO inflammatory response
Cell Biology
(CASE 2 - SBA)
Define - pyknosis
is the irreversible condensation of chromatin in the nucleus of a cell undergoing necrosis or apoptosis
Cell Biology
(CASE 2 - SBA)
Define - free radical damage
chemical radicals characterised by a single unpaired electron in the outer shell and highly reactive
Cell Biology
(CASE 2 - SBA)
Define - hypoxia
reduced O2 delivery to the tissues
Pathology
(CASE 4 - SBA)
Define - dysplasia
- pre-cancerous - ‘typical hyperplasia’ increased cell division
- cells look abnormal
- growth is dependent on initial stimulus and the acquisition of new driver mutations
- reversible
