What is the difference between plasma derived and cell derived chemical mediators of inflammation?
the cellular components involves leucocytes which normally resides in cell and must move to site of injury while plasma has cascade system which involves complment system , kinin ,coagulation and fibrinolysis system
What chemical mediators responsible to conjunctivitis?
Conjunctivitis, commonly known as pink eye, is often associated with various chemical mediators, primarily histamine, which is released during allergic reactions. Other mediators include leukotrienes and prostaglandins, which contribute to inflammation and increased vascular permeability. In bacterial or viral conjunctivitis, cytokines such as interleukins and tumor necrosis factor (TNF) can also play significant roles in the inflammatory response. These mediators together lead to the characteristic symptoms of redness, swelling, and discomfort in the conjunctiva.
What chemical mediators are released from mast cell?

Are interleukins chemical signals by which immune cells communicate with each other?
Yes, interleukins are a group of cytokines that act as chemical mediators used by immune cells to communicate with each other. They help regulate immune responses, including inflammation and cell differentiation.
What leukocytes responsible for releasing histamine and other mediatoir of inflammation?
The Basophil is the leukocyte that releases histamine and other mediators of inflammation; contain heparin, an anticoagulant.
Which inflammatory chemicals are blocked by nonsteroidal antiinflammatory drugs such as ibuprofen?
NSAID's mainy block PG's (prostaglandines) which are the mediators of inflammation .some block recruitment of WBC at the site of inflammation.
What is the description of basophil?
A trip or multilobed blood cell with purplish blue cytoplasmic granules. They release histamine and other mediators of inflammation, contains heparin.
What chemical causes inflammation?
Stool (poo) is the chemical substance produced by the body that is associated with the pain of inflammation, as inflammation is pain in your backside.
Why transient vasoconstriction happen in acute inflammation?
Transient vasoconstriction occurs immediately after injury followed by vasodilation. The vasoconstricion is the bodies defence against blood loss, but after this threat is passed the chemical mediators signal the vessles to dilate to allow platlets to get to the area via blood so that a clot can form. the acute inflammation occurs after the vasoconstriction, and with the vasodilation because the blood vessles also become more permeable allowing more fluid into the surrounding area. Increased fluid = inflammation.
What does not occur during inflammation?
During inflammation, the primary processes involve increased blood flow, immune cell recruitment, and the release of inflammatory mediators. However, processes such as tissue necrosis or apoptosis do not occur as a direct result of inflammation; instead, inflammation aims to promote healing and restore homeostasis. Additionally, inflammation does not lead to the immediate resolution of the underlying cause of injury or infection, which may require further intervention.
What are the main characteristics of inflammation?
Inflammation is a physiological response to infection or injury characterized by redness, heat, swelling, pain, and loss of function in the affected area. It is a crucial part of the body's immune response to protect and heal tissues. Inflammation involves the recruitment of immune cells, release of inflammatory mediators, and tissue repair processes.
When tissues are damaged macrophages release inflammatory mediators that cause?
When tissues are damaged, macrophages release inflammatory mediators such as cytokines and chemokines that initiate and amplify the inflammatory response. These mediators increase blood flow to the affected area, enhance vascular permeability, and attract other immune cells to help clear pathogens and debris. This process is essential for tissue repair and healing, but excessive inflammation can lead to further tissue damage and chronic conditions.
