LUNG FIBROSIS INDUCED BY BLEOMYCIN: STRUCTURAL
... A variety of cells of the lung are affected by

FOETAL WOUND HEALING

Decision making in wound management and closure

Regeneration or scarring: An immunologic perspective

Tendinosis, sometimes called chronic tendinitis, chronic tendinopathy, or chronic tendon injury, is damage to a tendon at a cellular level (the suffix ""osis"" implies a pathology of chronic degeneration without inflammation). It is thought to be caused by microtears in the connective tissue in and around the tendon, leading to an increase in tendon repair cells. This may lead to reduced tensile strength, thus increasing the chance of tendon rupture. Tendinosis is often misdiagnosed as tendinitis due to the limited understanding of tendinopathies by the medical community. Classical characteristics of ""tendinosis"" include degenerative changes in the collagenous matrix, hypercellularity, hypervascularity, and a lack of inflammatory cells which has challenged the original misnomer ""tendinitis"".
