MD

Back 57

Front 58

MD

Back 58

brain, pituitary adenoma, neoplasm, often causes metabolic disease because of continuous pressure on hypothalamus which is the center for controlling body apperance, appetitie, hair coat, --> adenoma causes long hair coat, high fever w/o infectious disease, increased appetite

Front 59

MD

Back 59

Kidney, hemoglobin nephropathy, (excess Cu stored in liver, causes necrosis of the liver, so liver releases Cu into circulation which lyses RBC which causes increased hemoglobin in kidney which looks like black streaks in tubules and gives dark red urine.)
