Inflammation is best defined as
A local response of living vascularized tissue to injury
An immune response only against infections
A reversible tissue injury
Healing by fibrosis only
Which of the following is NOT a cardinal sign of acute inflammation?
Redness
Swelling
Pain
Atrophy
The cardinal signs of inflammation were first described by
Celsus
Virchow
Galen
Hippocrates
Heat in acute inflammation is primarily due to
Vasodilatation
Increased vascular permeability
Leukocyte migration
Nerve stimulation
The earliest vascular change in acute inflammation is
Transient vasoconstriction
Arteriolar vasodilatation
Venous thrombosis
Endothelial injury
Increased vascular permeability in acute inflammation is mainly due to
Endothelial contraction
Endothelial necrosis
Leukocyte emigration
Platelet aggregation
Which mediator causes immediate transient increase in vascular permeability?
Histamine
Prostaglandins
Leukotriene B4
Interferon gamma
Margination of leukocytes occurs due to
Slowing of blood flow
Vasodilatation
Increased permeability
Endothelial proliferation
The principal leukocyte in acute inflammation is
Eosinophil
Neutrophil
Lymphocyte
Macrophage
Diapedesis refers to
Rolling of leukocytes

PECAM-1 (CD31) plays a major role in
Rolling
Adhesion
Diapedesis
Chemotaxis
Chemotaxis of leukocytes is mediated by
IL-2
