Dispel a kind of plaque of porridge of artery and does not dream of _'s general knowledge

Dispel a kind of plaque of porridge of artery and does not dream of _'s general knowledge
As early as decades ago, the scientists discovered a kind of plaque of artery porridge of later period on animal's model and can reverse. But because observe the means to restrict, mankind's reversion of the spot piece in later period has not been confirmed by pathology. So spot lump taken shape to think can't be dispelled in the past, treatment means can only stabilize the condition. Now, people can utilize high-resolution supersound and magnetic resonance imaging technology not to achieve and observe the artery wall shape continuously. Through the more same position pathological change, people find the spot pieces can all disappear in early and later period. At present, disappear the intersection of spot and treatment means of piece include, control apt to suffer from factor, promote lipid spread and degrade, lighten and continue and take place damaging etc. while being reverse.
It is apt to suffer from the factor to control and treat
Lipid has three sources in the spot piece: From the passive diffusion in the blood under the membrane while entering, spit etc. releasing across cell transshipping function under the membrane while entering, some cell necrosis through afterbirth swallowing and afterbirth. Among them passive diffusion is the aptest to be apt to suffer from the direct influence of the factor various atherosclerosis. Membrane under blood vessel just as one strain membrane, lipid pass in and out speed and direction of membrane in the blood vessel until density bad determining across the intersection of membrane and pressure difference and inner the intersection of membrane and aperture and penetrating area across membrane. Hyperlipemia has increased the density badly, hypertension has been improved, spread motive force, diabetes, smoke,etc. damages the endothelial cells of blood vessel, make the extraellular space increase, cause the membrane in the blood vessel to be penetrating and rise. So, should dispel a kind of plaque of porridge of artery, it is apt to suffer from the factor to control and treat these first, prevent the new damage from happening.
Promote reverse lipid to spread and degrade
These decades in the past, there was a mistaken idea, thought cholesterol and other fat were insoluble in water, only determine total cholesterol and high density lipoprotein cholesterol when the fat of blood is checked, and classify all cholesterol beyond cholesterol of high density lipoprotein as lipoprotein cholesterol of low density. But in fact, cholesterol, especially the intersection of cholesterol and ester solubility very much loud in water, serum hit cholesterol of high density lipoprotein beyond the cholesterol have 5%~10% by albumen combine the form store in, the lipid may play a key role while the spot piece disappear. Cholesterol, cholesterol ester dissolved is discharged outside the body or after consuming, cholesterol on the other positions such as lipid spot piece, biomembrane lipid double layers, lipoprotein will be dissolved into as supplementing, until forming the new dynamic equilibrium. So, the important mechanism that the spot piece disappears that reverse lipid is spread and transshipped, when the free lipid density in the blood is obviously reduced, know passive diffusion in the blood with lipid under the inner membrane, foam lipid in the cell too can consume because of cellular metabolism and afterbirth spit function reduce, thus make the spot piece shrink even disappear.
