Problems solved by technology

[0004] The existence of HAAF significantly increases the incidence of hypoglycemia in patients, and repeated hypoglycemia will further aggravate the degree of HAAF, so it will often fall into a vicious circle, seriously affecting the blood sugar control of patients
[0005] At present, several famous endocrinology laboratories abroad, led by Yale University, are actively exploring the mechanism and countermeasures of HAAF, but there is no breakthrough in treatment.

Embodiment 1

[0031] Take 2000g of the original medicinal material of Radix Astragali, add water and decoct three times, 1.5 hours each time, combine the decoction, filter, and concentrate the filtrate to 1g of the original medicinal material per 1ml, and use ethanol precipitation for two times. The ethanol content in the first solution is 75% and 85% for the second time, each time it was placed in cold storage for 12 hours, recovered ethanol and concentrated to 10 g of the original medicinal material per 1 ml, diluted with water for injection to 0.75 g of the original medicinal material per 1 ml, and placed in cold storage for 12 hours. Filter, concentrate the filtrate to 5g of the original medicinal material per 1ml, let it cool, adjust the pH value to 7.5 with 20% sodium hydroxide solution, boil, add 0.125% activated carbon, boil for 5 minutes, filter while it is hot, add water for injection Make it into 1000ml, filter it, adjust the pH value to 6.0-7.5 with 20% sodium hydroxide solution,...

Abstract

The invention discloses an application of an astragalus extract to the preparation of medicine for preventing and treating hypoglycemia hormone reverse regulation damage of diabetics. The astragalus extract comprises asparagoside IV with the content not lower than 0.08mg / ml. Animal experiments prove that the astragalus effective ingredients in the astragalus extract have the effect of rebuilding the hypoglycemia associated autonomic failure (HAAF) model rat partial hormone reaction, sugar sensitive parts of paraventricular nucleus (PVN), nucleus tractus solitarii (NTS) and the like in the brain can be activated, and corticotropin releasing factor (CRF) cerebral nuclei is activated, so an early warning mechanism of the organism on hypoglycemia is improved. Good treatment prospects are realized on one of the complications of the HAAF of the diabetes.

Description

[0001] This application is a divisional application of the following patent application: the application number is 200910056849.X, the application date is January 20, 2009, and the invention title is "A Radix Astragalus Extract and Its Preparation Method and Application". technical field [0002] The invention belongs to the field of traditional Chinese medicine and relates to an astragalus extract; in addition, the invention also relates to a preparation method and application of the astragalus extract. Background technique [0003] One of the complications of diabetes, HAAF, is an important obstacle for diabetics to obtain close to normal blood sugar control. Data show that intensive insulin therapy to reduce long-term complications of type 1 diabetes nearly tripled the incidence of hypoglycemia. The main mechanism of HAAF is that recurrent hypoglycemia greatly weakens the emergency regulation of hypoglycemia by adrenaline, glucagon and other counter-regulatory hormones, m...
