1. invention field
The present invention relates to be used for the treatment of or prevention of obesity or overweight composition and method.Particularly, the invention discloses preparation carry zinc, through the protein mixture that is derived from serum for example or breast of protease digestion and use the method for this mixture to the patient.
2. background of invention
Obesity is serious healthy prevailing disease.According to CDC (CDC) and national health and nutrition inspection investigation (NHANES) 1999-2000, estimate at 64% U.S. grownup and be that overweight or fat (overweight finger body surface index (BMI) is 25 or bigger, obesity refers to that BMI is 30 or bigger), and should numeral also increase.In 15 years, fat prevalence rate in the grownup increases above 30% in the past.Even it is shocking that more in 20 years, children and teen-age fat prevalence rate have increased by 100% in the past.Overweight and obese individuals is suffered from body illness such as high blood pressure, hypertension, high blood cholesterol levels, diabetes, insulin resistance, glucose does not tolerate, coronary heart disease and even psychological disorders as danger increase (the National Institutes of Health:Clinical Guidelineson the Identification of depressed and eating disorder, Evaluation, and Treatment of Overweight and Obesity inAdults, 1998, Bethesda, Maryland:Department of Health and Human Services, National Institutes of Health, National Heart, Lung, and Blood Institute; Mokdad etc., 2001, JAMA 289:76-79).
When the people became obesity, two kinds of situations can take place their intravital adipocyte (adipocyte): the volume of these cells and number both can increase.The intravital adipocyte number of people only increases at the people Shi Caihui that obtains to weigh sb. greatly.Body weight for humans follow the progressively increase or the reduction of adipocyte mean sizes usually than minor swing.Yet, the overall dimension that exists adipocyte to grow.Along with body weight obviously increases, produce new adipocyte by inoblast.Unfortunately, when the people loses by going on a diet when weighing sb. greatly, adipocyte only can shrink size, and its number but can not reduce.It is identical that the adipocyte number keeps in the human body of losing weight, this facts explain so difficulty of losing weight of why losing weight and keeping being obtained.Can more effectively reach these targets by the number that reduces adipocyte.
Present anti-obesity treatment concentrates on by medicine depress appetite, erstricted diet to be taken in, and perhaps uses the operation of losing weight in the most radical method.The popular appetite suppressant can be divided into two classes: the norepinephrine energy medicine such as the Phenylpropanolamine (Acutrim that influence the brain appetite center, Dexatrim), with the serotonergic medicine that influences the brain satiety center such as Phenfluoramine and dexfenfluramine (Williamson, 1999, JAMA281:278-279).Yet research shows that the neurophysiology of feed behavior is very complicated, and this makes that appetite inhibiting is difficult to realize.Simultaneously, Phenfluoramine and derivative thereof are with very deleterious side effect, and this forces these materials of forbidding.Attempt the patient that erstricted diet takes in and be difficult to finish the program of losing weight usually, and when they return old feed custom, tend to restore to the original state.Too much food is converted into the fat that replenishes the adipocyte that shrinks owing to losing weight rapidly.The size that reduces stomach by operation can the significant limitation food intake.Yet such operation has the side effect of himself, only recommends the individuality of serious obesity.In the liposuction program, can only from some body portion, remove fat.The result is to stay the fat quantity that the adipocyte in other position such as neck and the forearm can raise and lack of proper care, thereby produce ugly appearance.
Therefore be desirable to provide the non-intrusion type that works by the number that the reduces adipocyte therapy of losing weight.If adipocyte that can the target whole body (rather than only in limited zone) then will be especially useful.
