Question
1-Differentiate between the processes of resolution and regeneration what factor determine which of these processes will occur following an injury?
2-many factor influnce tissue healing Explain how the following factors could complicate or delay healing stating at least one example to illustrate each one
nature of tissue location of wound
nutritional status of injured individual
condition of the wound
drug being taken age of the individual
presence of foreign material in the wound
blood supply
presence of infection
degree of immobilization irrtation of the injured tissue
pre existing disease /medical problem
Explanation / Answer
1)
If tissue damage is minimal, then the resolution takes place. In this condition, the damaged tissue is repaired in a short period of time, gains its function and works properly. Regeneration or renewal is the curative procedure, which takes place in the cells that are capable of undergoing mitosis. For example, the skin cells and gastrointestinal cells regenerate rapidly and remove the dead cells and they are replaced with new cells.
2)
a)
Nature of tissue location of wound: For example, if a bullet hit the brain to remove that bullet from the brain requires further damage of some brain tissue during surgery.
b)
Nutritional status of injured individual: For example, malnutrition due to lack iof adequate amount of vitamins like K, C and E results the impartment of blood clotting and it future leads to inhibition or repairing of damaged tissue.
c)
Drug being taken age of the individual: Some drugs affect the age of individual, for example, The vitamin E regulate the age of an individual. People, who take pills of Vit-E, appear younger than the others.
d)
Condition of the wound: The condition of wound is determined by the anticlotting agents. For example, wounded people who administrated with anticlotting medication reduce the risk of blood loss, and therefore wound healing quickens.
d)
Presence of foreign material in the wound: The presence of foreign material in the wound increases the risk of infection as a result the impairment of wound closure.
e)
Blood supply: It is an important physiological function for wound healing, because blood transports the wound healing factors to the site of damage and heal the damaged tissue. If the blood supply has impaired to the site of wound, it would results formation of embolus.
f)
Presence of infection: The infection also inhibits the healing of a wound.
g)
Degree of immobilization irritation of the injured tissue: broken bones, if not immobilized, do not heal properly.
