fibro-, fibr-, fiber- +

(Latin: fiber [an elongated, threadlike structure]; a combining form denoting a relationship to fibers)

fibrinogenesis
The formation or production of fibrin.
fibrinogenic, fibrinogenous
1. Referring to or relating to fibrinogen.
2. Producing fibrin which forms the essential portion of the blood clot.
fibrinogenopenia
1. A concentration of fibrinogen in the blood that is less than what is considered to be normal.
2. The reduction or decrease in the amount of fibrinogen in the blood, usually because of a liver disorder.
fibrinoid
1. Resembling fibrin.
2. A homogenous acellular material similar to fibrin, found normally in the placenta and formed in connective tissue and in the walls of blood vessels in certain disease conditions.
fibrinoid change
Alteration in connective tissues in response to immune reactions.

The tissue becomes swollen, homogenous, and bandlike.

fibrinolysis
1. A normal ongoing process that dissolves fibrin and results in the removal of small blood clots.
2. The dissolution of fibrin by enzymatic action.
3. A complicated system of biochemical reactions for lysis (dissolution or destruction of cells such as blood cells) of clots in the vascular system.

The insoluble protein fibrin is broken down by the enzyme plasmin which is activated at the same time as the coagulation process of blood.

There is normally a balance between coagulation and fibrinolysis; an abnormal increase in the latter causes excessive bleeding.

fibrinolytic drugs
A group of drugs, also know as thrombolytics, that have the ability to break down the protein fibrin, the primary constituent of blood clots.

The drugs work by activating plasminogen to form plasmin which degrades fibrin and breaks up blood clots.

fibrinopenia
Fibrin and fibrinogen deficiency (protein synthesized by the liver and present in blood plasma) in the blood.
fibrinosis
Excess of fibrin in the blood.
fibrinuria
Passage of fibrin in the urine.
fibroadenia
Fibrous degeneration of glandular tissue.
fibroadenoma, fiberadenoma
A benign tumor of glandular epithelium (membranous tissue covering internal organs and other internal surfaces of the body) containing fibrous elements.

The most common benign tumor is of the breast, often occurring in young women.

fibroadipose
1. Relating to or containing both fibrous and fatty structures.
2. Fibrous degeneration of glandular tissue.
fibroblast
Any cell, or corpuscle, from which connective tissue is developed.
fibroblastoma
A tumor of connective tissue, or fibroblastic, cells.
