Caseation
Definition:

(20) Tuberculostearic acid (TBSA) was also detected in nine of 16 specimens from the head and neck region with non-caseating granulomas suspected, but not confirmed, to be tuberculosis.
Degeneration
Definition:
(n.) The act or state of growing worse, or the state of having become worse; decline; degradation; debasement; degeneracy; deterioration.
(n.) That condition of a tissue or an organ in which its vitality has become either diminished or perverted; a substitution of a lower for a higher form of structure; as, fatty degeneration of the liver.
(n.) A gradual deterioration, from natural causes, of any class of animals or plants or any particular organ or organs; hereditary degradation of type.
(n.) The thing degenerated.
Example Sentences:
(1) Thus, our results indicate that calbindin-D28k is a useful marker for the projection system from the matrix compartment and that its expression is modified in patients with progressive supranuclear palsy and striatal degeneration.
(2) Achilles tendon overuse injuries exist as a spectrum of diseases ranging from inflammation of the paratendinous tissue (paratenonitis), to structural degeneration of the tendon (tendinosis), and finally tendon rupture.
(3) Electroretinographic (ERG), morphometric and biochemical studies on retinas from monkeys or rats reveal that moderate level developmental lead (Pb) exposure produces long-term selective rod deficits and degeneration.
(4) of rats resulted in cell death and terminal degeneration in entorhinal, insular, and posterior cingulate cortices, and in the CA1, CA3 and dentate gyrus sectors of hippocampus.
(5) Certain underlying factors in several types of retinal degeneration are first discussed, followed by characteristics of diabetic maculopathy and of other types of macular degeneration including that due to aging.
(6) Hyperopia was more common in younger persons, but senile cataract, macular degeneration and palpebral dermatochalasis or blepharochalasis were more common in older persons.
(7) Since only a few of these medium sized terminals in any one cluster degenerate after tectal lesions, and none degenerate after cortical lesions, it is suggested that the morphological arrangement of these clusters may permit the convergence of axons from several sources, some of which are unidentified, onto the same dendritic segment.
(8) Age-related macular degeneration (ARMD) is one of the leading causes of severe visual loss in the United States.
(9) Deafferentation of certain brain regions in adult animals results in (1) the disappearance of degenerating axon terminals and (2) in the temporary persistence of vacant postsynaptic sites.
