LAB2 - Morphologic Pattern and Cellular Adaptation Injury Flashcards
occurs when the cell is unable to adapt to the
injurious stimuli
Cell injury
2 Types of Cell Injury
1) Reversible Cell Injury
2) Irreversible Cell Injury
Cell injury may be brought about by several injurious stimuli
affecting the cells and the tissues, injury may be seen as any
of or a combination of the following patter
o Cellular swelling or lysis
o Cytoplasmic loss of glycogen
o Nuclear pyknosis or lysis
o Cellular fatty change
anything that is Beyond normal value/ appearance/ description is called
pathological
accumulation of triacylglycerol in hepatocytes
Steatosis
in Steatosis, what is accumulated in liver cells
triacylglycerol
is Fatty Change reversible?
yes
Fatty Change is Observed in the following Tests
Biochemical Assays
Ultrasound
Blood Analysis
what is observed in Biochemical Assays if there’s a fatty change
increased lipid profile
(triglycerides, HDL, LDL)
what is observed in ultrasound if there’s a fatty change
fatty change itself
what is observed in blood analysis if there’s a fatty change
increased Alanine transaminase
(SGPT/ ALT)
Aspartate transaminase (SGOT/
AST)
Polygonal cells with well-defined cell borders
Hepatocytes
Is a common finding in liver biopsy specimens
Steatosis–accumulation of triacylglycerol in
hepatocytes
Contains one or more nuclei (depending onto the
maturity)
Hepatocytes
in intracellular accumulatios, the liver with deranged lipoprotein transport from injury most often because of alcoholism leads to accumulation of ___
lipid in the cytoplasm of the hepatocytes
Staining used for analyzing fatty changes on heart and liver cells
hematoxylin and eosin staining
describe the appearance of serum pf a patient with steatosis
chylous or turbid
it can happen in cellular injury
intracellular accumulations
deranged lipoprotein transport from injury (alcoholism) leads to accumulation of lipids in the cytoplasm of hepatocytes
fatty metamorphosis
ü Steatosis in the liver can be present in either a
_____ or ____ pattern.
microvesicular or a macrovesicular
The most common form of steatosis
Macrovesicular steatosis
2 types of steatosis
macro and micro vesicular
Histologically characterized by hepatocytes
containing a single vacuole of fat filling up the
hepatocyte and displacing the nucleus to the cell’s
periphery
Macrovesicular steatosis
once vacuoles are observed in the ____
examination it is considered as pathological
microscopic
Fatty degeneration of the heart is a retrogressive condition in
which fat droplets are found in the ___
myocardial sarcoplasm
Blood Analysis of farty change in the heart
Increased SGPT/ SGOT
in fatty change in the heart, there will be a significant increase of __
triglycerides
: the cytoplasm of smooth-muscle cells and striated
and myocardial muscle fibers
Sarcoplasm
cardiac muscle tissue characteristics
striated muscle fibers
branched with intercalated disc
uninucleated
involuntary heart movement
appearance or characteristics of cells in congestive heart failure
swollen cells are seen with compressed microvasculature
small clear vacuoles (vacuolar degeneration)
