What's the difference between accumulation and congestion?

Accumulation


Definition:

  • (n.) The act of accumulating, the state of being accumulated, or that which is accumulated; as, an accumulation of earth, of sand, of evils, of wealth, of honors.
  • (n.) The concurrence of several titles to the same proof.

Example Sentences:

  • (10) Aside from these characteristic findings of HCC, it was important to reveal the following features for the diagnosis of well differentiated type of small HCC: variable thickening or distortion of trabecular structure in association with nuclear crowding, acinar formation, selective cytoplasmic accumulation of Mallory bodies, nuclear abnormalities consisting of thickening of nucleolus, hepatic cords in close contact with bile ducts or blood vessels, and hepatocytes growing in a fibrous environment.

  • (12) Our results show that large complex lipid bodies and extensive accumulations of glycogen are valuable indicators of a functionally suppressed chief cell in atrophic parathyroid glands.
  • (13) Much information has accumulated on the isolation and characterization of a heterogeneous group of molecules that inhibit one or more of the bioactivities of interleukin 1.
  • (14) The mechanism by which K+ accumulates in the follicle was insensitive to ouabain, so that a typical Na+, K(+)-ATPase mechanism does not appear to be involved.
  • (15) The data shows a dissociation between ferritin synthesis, cellular accumulation and secretion for which the mechanisms have still to be elucidated.
  • (16) The rate of accumulation was highest late in infection and only the slower migrating form incorporates significant amounts of glucosamine.
  • (17) Initiation of the alternative pathway by the cryptococcal capsule is characterized by a lag in C3 accumulation and the appearance of a limited number of focal initiation sites which resemble those observed when the alternative pathway is activated by zymosan and nonencapsulated cryptococci.
  • (18) Accumulating evidence indicates that for most tumors, the switch to the angiogenic phenotype depends upon the outcome of a balance between angiogenic stimulators and angiogenic inhibitors, both of which may be produced by tumor cells and perhaps by certain host cells.
  • (19) The aim of our experiments was to investigate firstly whether during an acute inflammatory process platelets accumulate in the inflamed area and secondly whether the inflammation has an effect on the properties of the platelets.
  • (20) The accumulated evidence would strongly favor an affirmative answer.

Congestion


Definition:

  • (n.) The act of gathering into a heap or mass; accumulation.
  • (n.) Overfullness of the capillary and other blood vessels, etc., in any locality or organ (often producing other morbid symptoms); local hyper/mia, active or passive; as, arterial congestion; venous congestion; congestion of the lungs.

Example Sentences:

  • (1) Macroscopic lesions included mild congestion of the gastric mucosa and focal consolidation of the lung.
  • (2) Lisinopril increases cardiac output, and decreases pulmonary capillary wedge pressure and mean arterial pressure in patients with congestive heart failure refractory to conventional treatment with digitalis and diuretics.
  • (3) These lanes encourage cyclists to 'ride in the gutter' which in itself is a very dangerous riding position – especially on busy congested roads as it places the cyclist right in a motorist's blind spot.
  • (4) After 40 minutes of coronary occlusion and 20 minutes of reflow, significant cardiac weight gain occurred in association with characteristic alterations in the ischemic region, including widespread interstitial edema and focal vascular congestion and hemorrhage and swelling of cardiac muscle cells.
  • (5) The degree of venous congestion in the lungs of patients with mitral stenosis varies with the phases of respiration.
  • (6) Stroke was the cause of 2 and congestive heart failure the cause of 4 deaths.
  • (7) In this ewe, and in 4 of 7 other sheep diagnosed as having abomasal emptying defects, aspartate transaminase and sorbitol dehydrogenase activities were high, and histopathologic evidence of hepatic congestion and ischemia was found.

  • (12) The drugs used in early studies - diuretics, vasodilators and reserpine - greatly improved mortality from malignant hypertension, apoplectic stroke and congestive heart failure, but had little or no effect in persons with milder degrees of elevated blood pressure, who constitute the vast majority of hypertensives.
  • (13) In the other 6 patients with congestive heart failure and in 4 controls, saralasin produced either no change or slight increases in systemic vascular resistance.
  • (14) In patients with preexistent congestive heart failure (CHF), predicted cumulative survival rates at 1, 3, and 5 years were 78%, 69%, and 57%, respectively, for group 1 (n = 23) and 90%, 83%, and 75%, respectively, for group 2 (n = 16).
