Part 11 Flashcards
A patient with tissue trauma was taken a blood sample for the determinati- on of blood clotting parameters. Specify the right sequence of extrinsic pathway activation:
III - VIIa - Xa
Autopsy of a man who died from chronic cardiacvascular collapse revealed “tiger heart”. Sidewards of endocardium a yellowish-white banding can be seen; myocardium is dull, dark-yellow. What process caused this pathology?
Fatty parenchymatous degeneration
Parents with an ill child consulted an infectionist. They had been working in one of Asian countries for a long time. The child has sallow skin, loss of appeti- te, laxity, enlarged liver, spleen, peripheral lymph nodes. What protozoal illness can be suspected?
Visceral leishmaniasis
Healthy parents have got a fair- haired, blue-eyed girl. Irritability, anxiety, sleep and feeding disturbance developed in the first months of the infant’s life. Neurological examination revealed developmental lag. What method of genetic investigation should be used for the exact diagnosis?
Biochemical
The process of heart transplantati- on determined the viability of myocardi- al cells. The determination of what myocardium parameter is the most important?
Rest potential of cardiomyocytes
The calcium canals of cardiomyocytes have been blocked on an isolated rabbit’s heart. What changes in the heart’s activity can result from it?
Decreased rate and force of heart beat
Microscopic examination of the enlarged neck gland of a 14-year-old girl revealed destruction of the ti- ssue structure of the node, absence of the lymph follicles, sclerotic areas and necrosis foci, cell constitution of the node is polymorphous, lymphocites, eosinophi- les, big atypical cells with multilobular nuclei (Beresovsky-Sternberg cells) and mononuclear cells of the large size are present. What is the most likely diagnosis?
Lymphogranulomatosis
As a result of the damage of one of the Atomic Power Plant reactors the run- out of radioelements took place. People in the high-radiation area were radiated with approximately 250-300 r. They were immediately hospitalized. What changes in the blood count would be typical for the victims?
Lymphopenia
Dystrophic alterations of heart are accompanied with dilation of heart cavities, decreased force of heart contractions, increased blood volume that remains during systole in the heart cavity, vein overfill. What heart condition is it typical for?
Myogenic dilatation
Nowadays about 50 minor bases have been found in the t-RNA structure besides the main four nitrogenous bases. Choose the minor nitrogenous base:
Dihydrouracil
