Glossary

Pathophysiology (from Greek words): pathos - illness, suffering; physis - nature, function; logos - study
Pathophysiology is the science about the functions of a sick organism.

Pathophysiology is scientific study of disease - its nature, cause, mechanisms and effects. It is the science about general laws of pathological processes and diseases. It studies "why" and "how" disease occurs and develops.

Патофизиология (от греч. Pathos - болезнь, physis – природа, функция, logos - учение) – наука о функциях больного организма.

Патофизиология изучает общие закономерности возникновения, развития и исходов болезней.

Патофизиология (грекше Pathos – ауру, дерт, physis – табиғат, қызмет, logos - ғылым) – ауруға шалдыққан организмнің қызметі туралы ғылым.

Патофизиология аурулардың пайда болуы, дамуы және аяқталуының негізгі заңдылықтарын зерттейді.

Purposes of pathophysiology

· Study the questions of general etiology

· Study the questions of pathogenesis

· Investigation methods of experimental therapy

· Formation of medical mode of thinking

Задачи патофизиологии

· Изучение вопросов общей этиологии

· Изучение вопросов патогенеза

· Разработка методов экспериментальной терапии

· Формирование врачебного мышления

Патофизиологи яның міндеттері

· Жалпы этиология сұрақтарын зерттеу

· Патогенез сұрақтарын зерттеу

· Экспериментік емдеу тәсілдерін өңдеу

· Дәрігерлік ойлауды қалыптастыру

 

The main method of pathophysiology – is pathophysiological experiment.

The main feature of pathophysiological experiment is modelling of human illness at animals.

 

Основной метод патофизиологии – патофизиологический эксперимент.

Особенность патофизиологического эксперимента: моделирование болезней человека у животных.

Патофизиологияның негізгі тәсілі – патофизиологиялық эксперимент.

Патофизиологиялық эксперименттің ерекшелігі: адам ауруларын жануарларда үлгілеу.

 

Nosology – is the study of disease in general (from Greek word nosus – disease):

Нозология – учение о болезни (от греч. nosus-болезнь)

Нозология – ауру туралы жалпы ілім (грекше nosus-ауру).

 

“Health is a state of complete physical, psychological and social well-being, and is not just the absence of illnesses or physical defects” (WHO).

«Здоровье – это состояние полного физического, духовного и социального благополучия, а не только отсутствие болезней или физических дефектов» ВОЗ.

«Денсаулық – бұл аурудың немесе физикалық ақаулардың болмауы ғана емес, физикалық, психикалық және әлеуметтік толық сәттілік жағдай» БДСҰ.

 

“Disease is normal life disturbances under the influence of pathogenic factors, it is characterized by restriction in adaptation to the environment and reduction in work capacity” (I.Petrov)

 «Болезнь – нарушение нормальной жизни организма под влиянием различных повреждающих факторов, характеризующееся ограничением приспособления к окружающей среде и снижением трудоспособности» И.Петров.

Ауру – әртүрлі зақымдаушы агенттің әсерінен қоршаған ортаға бейімделуінің шектелуімен және еңбекке қабілетінің төмендеуімен организмнің қалыпты өмірінің бұзылысы» И.Петров.

 

Predisease is a condition between health and illness.

Предболезнь – состояние между здоровьем и болезнью.

Ауру алды – денсаулық пен ауру арасындағы аралық жағдай.

 

Pathological reaction – (re-against) – is short-term, unusual, inadequate organism’s responce to different factors

Патологическая реакция –(re - против, action - действие) – кратковременная, необычная (неадекватная) реакция организма на какое-либо воздействие

Дерттік серпіліс –(re – қарсы, action - әсер, серпіліс) –

Қандай да бір әсерге организмнің қысқаша, биологиялық мәнсіз және сәйкессіз жауабы

 

Pathological process – is a combination of pathological and protective - adaptive reactions to damage.

Патологический проц есс – сочетание патологических и защитно-приспособительных реакций при повреждении.

Дерттік үрдіс – зақымдану кезінде әрі қорғану бейімделу және әрі зақымдану серпілістерінің жиынтығы

Typical (general) pathological processes

• have the same pathogenesis in different kinds of animals and men (monopathogenesis)

• Have many causes (multicausality)

• develop in different organs and tissues

• have more or less expressed protective - adaptive value

• are formed during evolution

Типовые патологические процессы:

· протекают однотипно у разных видов животных и человека (монопатогенез)

· характерна многопричинность (полиэтиологичность),

· развиваются в разных органах и тканях,

· имеют более или менее выраженное защитно-приспособительное значение,

· выработаны в ходе эволюции.

Біртектес дерттік үрдістер:

· Адам мен әртүрлі жануарларда бірдей деңгейде өтеді,

· Көп себепті (полиэтиологиялы),

· әртүрлі ағзалар мен тіндерде өтеді,

· айқындығы аз немесе жоғары қорғану-бейімделулік маңызы бар,

· эволюцияда барысында түзілген

 

Pathological state is firm departure from the norm, which doesn’t have adaptive value for an organism.

Патологическое состояние – стойкое отклонение от нормы, не имеющее приспособительного значения для организма.

Дерттік жағдай –организм үшін кері биологиялық мәні бар қалыптан тыс тұрақты ауытқу.

 

Reanimation is resuscitation of an organism. It is possible at reversible stages of dying.

Реанимация – оживление организма. Возможна на обратимых этапах умирания.

Реанимация –организмді тірілту. Өлімнің қайтымды сатыларында жүргізуге мүмкіндік бар.

Glossary:

Reactivity i s  a certain organism’s response to environmental factors (N.N.Sirotinin).

Reactivity is organism’s property as a whole to respond to environmental factors by changing its  life (A.D.Ado).

Реактивность ( Re – против; action - действие ) - это свойство организма отвечать определенным образом на воздействие факторов окружающей среды (Н.Н.Сиротинин).

Реактивность- это свойство организма как целого отвечать изменением жизнедеятельности на воздействие окружающей среды (А.Д.Адо).

Реактивтілік ( Re – қарсы; action - әсер ) - сыртқы ортаның әсерлеріне организмнің белгілі бір жолмен жауап қайтару қасиеті (Н.Н.Сиротинин).

Реактивтілік – сыртқы орта ықпалдарының әсерлеріне организмнің, оның жекелеген ағзалары мен жүйелерінің тіршілігін өзгертіп жауап қайтару қасиеті немесе қабілеті (А.Д.Адо)

Normergy is the adequate organism’s response to pathogenic factors

Нормергия- это адекватный ответ организма на воздействие раздражителя

Нормергия – әдеттегі тітіркендіргішке организмнің қалыпты жауабы, мұнда нормергиялық жауап серпілісі туралы айтылады

Pathergy is inadequate response to pathogenic factors

Hyperergy is more intensive reaction then normal (high reflexes, allergic reactions, child reactivity)

Hypoergy is low reaction of physiological systems to surroundings (asymptomatic diseases), reactivity of a senile organism)

Anergy is absence of organism’s response (coma, shock, narcosis)

Disergy    is inverted response, opposite to normal (vasodilation to cold, expansion of a pupil to light)

Патергия - неадекватная ответная реакция:

· гиперергия- бурные физиологические реакции, значительно превышающие необходимый уровень реагирования (реактивность детского организма)

· гипергия - слабые реакции физиологических систем, недостаточные для полноценного ответа организма на повреждающее воздействие (вялое течение болезней с неясными, стертыми признаками) (реактивность старческого организма)

· анергия - отсутствие ответных реакций (носительство, отсутствие реакций в состоянии комы, при наркозе)

· дизергия - извращенные ответные реакции (расширение сосудов на действие низкой температуры, расширение зрачка на свет)

  Патергия - қалыптан тыс жауап:

· гиперергия– реактивтіліктің жоғарылауы

· гипергия – органихм реактивтілігінің төмендеуі (аурулар сылбыр, белгілері айқын болмай өтеді) (қарттардың реактивтілігі)

· анергия - реактивтіліктің мүлде болмауы (өзі ауырмай микробтардың тасымалдаушылары болады, терең кома, сілейме, наркоз жағдайларындағы)

· дизергия - қалыптан тыс, бұрмаланған жауап (төмен температураға тамырлардың кеңеюі, жарыққа көз қарашығының кеңеюі)

Organism’s resistance is resistance against pathogenic factors.

Резистентность организма - устойчивость организма против болезнетворных воздействий (resisteo-сопротивление).

Организм төзімділігі – ауру туындататын ықпалдарға организмнің тұрақтылығы (resisteo-қарсы тұру)

 

Species reactivity - is a complex protective reactions of different species of animals to surroundings, general type of reactivity (ex. migration of birds, hibernation of mammal, species immunity)

Виды реактивности

Видовая - наиболее общий вид реактивности, особенности реагирования целого вида (миграция птиц, зимняя спячка млекопитающих, видовой иммунитет)

Түрлік – реактивтіліктің жалпы түрі, бүкіл бір түрдің жауап қайтару ерекшелігі (құстардың мекенін ауыстыруы, сүтқоректілердің қысқы ұйқысы, түрлік иммунитет)

 

Group reactivity is the response of several individuals within the species (ex. sex, age, constitution, race, group of blood)

Групповая - особенности реагирования отдельных групп индивидуумов в пределах вида (пол, возраст, конституция, расовая принадлежность, группа крови и др.)

  Топтық - түрдің ішіндегі кейбір топтардың жауап қайтару ерекшелігі (жыныс, жас, конституция, нәсілдік ерекшелік, қан топтары, ж.б.)

 

Individual reactivityis an individual's particular response unique to each person

Индивидуальная - особенности реагирования индивидуума, определяет уникальность индивидуума

Даралық - еке тұлғалардың реактивтілігі, әр адам қайталанбайтын тұлға екендігін көрсетеді

 

Physiological reactivity is adequate organism’s response

Pathological reactivity is inadequate organism’s response

Specific (immunological) reactivity is organism’s response to antigens

Специфическая, иммунологическая реактивность – ответная реакция на антиген

Арнайыланған немесе иммунологиялық реактивтілік – антигеннің әсеріне антидене

Constitution (from Lat. Constitutio - state property) – is a set of morphological and functional characteristics of the body, forming the state of its reactivity, formed on the basis of inherited and acquired properties.

Конституция (от лат. constitutio – состояние, свойство) - это совокупность морфологических и функциональных особенностей организма, формирующих состояние его реактивности, сложившихся на основе наследственных и приобретенных свойств.

Glossary

Cell injury is cellular structure and function damages which persists after the removal of the damaging agent

Повреждение клетки это нарушение структуры и функции клетки, сохраняющееся после удаления повреждающего агента

Жасушаның зақымдануы – бұл жасушаның құрылымы мен қызметінің зақымдаушы жайттың әсерінен кейін дамитын бұзылыс

Glycocalyx is thin cell cover, formed by glycoproteins and glycolipids functioning as charged molecular sieve. Destruction of Glycocalyx leads to decrease in resistance to cell injury. Гликокалекс – тонкая пленка, покрывающая клеточные поверхности, образована полисахаридными цепями, гликопротеидами, гликолипидами, функционирует как заряженное молекулярное сито. Нарушение образования гликокалекса уменьшает устойчивость клетки к повреждению.

Гликокалекс – молекулярлық сүзгі қызметін атқарушы, гликолипидті, гликопротеидті, полисахаридті тізбектен тұратын жасушаның беткей қабатын көмкеруші жұқа қабық.   

 

Cell cycle.: G 0 (gap 0) phase - resting phase, G1 - is the preparation for DNA synthesis, S (synthetic) phase - is DNA synthesis, G2 ph. – preparation for mitosis, M - mitosis

Фазы жизненного цикла клетки: G0  ®  G1 ® S ® G2  ® M

G0 - состояние покоя клетки; G1- пресинтетическая фаза, подготовка к синтезу ДНК; S - синтез ДНК; G2 - премитотическая фаза, подготовка к митозу, M – митоз. К различным воздействиям клетка по-разному чувствительна в разные фазы цикла.

Жасушаның тіршілік айналым кезеңдері: G0 ®  G1 ® S ® G2  ® M

G0 - жасушаның тыныштық жағдайы; G1- синтез алды кезең, ДНК синтезіне дайындық кезең; S – ДНК синтезі; G2 – митоз алдындағы кезең, митозға дайындық кезең, M – митоз. Жасушаның әртүрлі ықпалдарға айналым кезеңдеріне әртүрлі сезімталдығы байланысты.

           

Acute cell injury occurs when pathogenic agents are intensive, their action is of short duration

Острое повреждение клетки развивается когда достаточно интенсивный этиологический фактор действует непродолжительное время

Жасушаны ң ж іт і за қымдануы – зақымдаушы жайт қысқа уақытта қатты әсер еткенде дамиды

Chronic cell injury occurs when pathogenic agents are less intensive but their action is prolonged

Хроническое повреждение клетки развивается когда этиологический фактор малой интенсивности действует продолжительно,

Жасушаның созылмалы зақымдануы – қарқыны аз зақымдаушы жайт ұзақ уақыт әсер еткенде дамиды.

 

Direct (primary) cell injury is due to direct effects of etiological factors

Indirect (secondary) cell injury is the result of the primary injury. It is due to mediators of damage.

Partial damage occurs when there is injury to a part of the cell, as a rule, it is reversible, ie. cell recovers its structure and function

Total damage is irreversible.

Прямое повреждение клетки (первичное) - непосредственное повреждение клетки этиологическим фактором.

Жасушаның тікелей зақымдануы (біріншілік) – жасушаның этиологиялық жайттың әсеріне байланысты зақымдануы

Опосредованное повреждение клетки (вторичное) - является следствием первичного, развивается под действием БАВ - медиаторов повреждения

Жасушаның тікелей емес қосымшы зақымдануы (екіншілік) – біріншілік себепкер ықпалдың салдарынан пайда болатын белсенді биологиялық заттардың әсерінен дамиды.

Парциальное повреждение клетки – повреждается только часть клетки, как правило, оно бывает обратимым, т.е. клетка восстанавливает свою структуру и функцию

Жасушаның үлестік зақымдануы – жасушаның тек бір бөлігінің зақымдануы, әдетте ол қайтымды болады, жасуша өзінің құрылымы мен қызметін қалпына келтіреді   

  

Specific lesions are due to specific action of the etiologic factor (cyanide inactivates cytochrome

oxidase in mitochondria, high temperature leads to protein coagulation).

Nonspecific lesions are present in every injured cell (increased membrane

 permeability, inhibition of enzyme activity, inhibition of membrane pumps, ionic imbalance,

disorders of energy supply, intracellular acidosis)

Специфические проявления повреждения обусловлены специфическим действием этиологического фактора (цианиды блокируют цитохромоксидазу; высокая температура вызывает коагуляцию белков)

Зақымданудың спецификалық көрінісі - этиологиялық жайттың тікелей арнайы әсер етуінен (цианидтер цитохромоксидазаны тежейді; жоғарғы температура нәруыздың коагуляциясын шақырады) дамиды.

Неспецифические проявления повреждения сопровождают любое повреждение клеток (повышение проницаемости мембран, угнетение активности транспортных ферментов, мембранных насосов, нарушение рецепторного аппарата клеток, нарушение функционирования ионных каналов, нарушение ионного состава клетки, нарушение энергообразования, внутриклеточный ацидоз).

Жасушаның арнайы емес көрінісі жасушаның кез келген зақымдануында (мембрана өткізгіштігінің жоғарылауымен, ферменттердің белсенді тасымалдануының бөгелуінің, сүзгіш мембранасының, жасуша аппаратының рецепторлы бұзылысымен, иондық каналдық қызметінің және жасушаның иондық құрамының, энергиямен қамтамасыз етілуінің бұзылысымен, жасушаішілік ацидоз) байқалады.

 

Necrosis is irreversible damage to cells, due to the action of pathogenic agents, is the result of destructive enzyme activity with the development of two competing processes: the enzymatic digestion of the cell (colliquation (liquefaction) necrosis) and protein denaturation (coagulation necrosis)

  Некроз – необратимое повреждение клетки, развивается под действием повреждающих факторов, является результатом разрушающего действия ферментов с развитием

двух конкурирующих процессов: ферментативное переваривание клетки (колликвационный, разжижающий некроз) и денатурация белков (коагуляционный некроз)

Некроз - жасушаның қайтымсыз зақымдануы, зақымдаушы жайттардың ықпалынан дамитын екі бәсекелес үрдістің, ферменттердің бүліндіргіш әсерінің нәтижесінде дамитын: жасушаның ферментативті қорытылуы (колликвациялы, сұйылтушы некроз) және нәруыздыңденатурациясы (коагуляциялық некроз).

 

Paranecrosis is notable, but reversible changes in the cell: cytoplasm clouding and vacuolization, the the appearance of coarse sediments, increased permeability for different dyes.

Паранекроз - заметные, но обратимые изменения в клетке: помутнение цитоплазмы, вакуолизация, появление грубодисперсных осадков, увеличение проникновения в клетку различных красителей.

Паранекроз – жасушаның қайтымды өзгерісі: цитоплазманың бұлыңғырлануы, вакуолизациясы, ірі дисперсті тұнбалардың пайда болуы, жасушаға әртүрлі бояғыштардың сорылуының жоғарылауы.

 

Necrobiosis – is the state "between life and death" (from necros - dead and bios - live), changes in the cell prior to its death. Necrobiotic cell may return to its original state after elimination of the reasons that caused necrobiosis.

Некробиоз - состояние «между жизнью и смертью» (от necros - мертвый и bios - живой); изменения в клетке, предшествующие ее смерти. При некробиозе в отличие от некроза возможно возвращение клетки в исходное состояние после устранения причины, вызвавшей некробиоз.

Некробиоз - «өлім мен өмір арасы» жағдайындағы (necros – өлі және bios - тірі); жасушаның өліміне әкелетін өзгерісі. Некробиоздың некроздан айырмашылығы некробиоз тудырған себептердің әсерінен кейін жасушаның бастапқы жағдайына қайта келу мүмкіндігі.

 

Apoptosis is genetically programmed cell death; controlled process of cellular self-destruction.

Апоптоз - генетически запрограммированная гибель клетки, контролируемый процесс самоуничтожения клетки.

Апоптоз – жасушаның алдын-ала бағдарланған гендік ақпаратың қадағалауы бойынша тіршілігін жоюы.

 

Apoptotic bodies – are extracellular fragments of the nucleus, surrounded by membranes. They are the results of apoptotic destruction of cells

Апоптотические (апоптозные) тельца - внеклеточные фрагменты ядра, окруженные мембраной, на которые распадается клетка при апоптозе

Апоптотикалық (апоптоздық) денешік – ядроның жасушасыртылық фрагменті, мембранамен қоршалған, апоптоз кезінде жасушаның ыдырауының салдары. 

1) Receptor mechanism of apoptosis realization. Is carried out with the help of " receptors of death»  (Fas, TNF-RI, TNF-RII, DR-3, DR-5, etc.)

2) Mitochondrial mechanism of apoptosis is due to increase in permeability of mitochondrial membranes and release of cytochrome C, apoptosis-inducing factor (AIF) and other proapoptotic proteins into the cytoplasm with further activation of caspase 3.

 

3) P53- mediated mechanism of apoptosis. Protein p53 induces the transcription of apoptogenic factors (Bax, Fas-receptor, DR-5, etc.)

4) Perforin- granzyme mechanism of apoptosis. Characteristic of T-killer cells that release perforin. Perforin forms channels in the cytoplasmic cell membranes through which the cell receives secreted by T-killers granzymes - proteolytic enzymes that activate caspase 3.

 

1. Рецепторный механизм реализации апоптоза. Осуществляется с помощью «рецепторов смерти» (Fas, TNF-RI, TNF-RII, DR-3, DR-5 и др.)

Апоптозды іске асырудың рецепторлы механизмі. «Өлім рецепторы» көмегімен қамтылады.

2. Митохондриальный механизм реализации апоптоза. При повышении проницаемости мембран митохондрий и выхода в цитоплазму цитохрома С (Cyt С), апоптозиндуцирующего фактора (AIF) и других проапоптических белков с дальнейшей активацией каспазы 3

Апоптозды іске асырудың м итохондриаль ды механизм і. Митохондрий мембранасының жоғары өткізгіштігі кезінде цитоплазмаға апопотозды сергітетін фактор (AIF) цитохром С шығарылуын (Cyt С), және апоптозды күшейтетін нәруыздар каспаза 3 белсенділін арттырады.
