Problems solved by technology

The causes and locations of acute pancreatitis and colitis are different, and their therapeutic intervention strategies are also different. For example, butyric acid and Clostridium butyricum can alleviate colitis, but have no protective effect on acute pancreatitis

Embodiment 1

[0034] Example 1. Establishment of acute pancreatitis model

[0035]Eight-week-old female BALB / C mice were randomly divided into a control group (control), an acute pancreatitis group (AP), and a long-chain inulin prevention group (ITF IV). The mice in the group and the prevention group were injected with normal saline (0.90%) and cerulein (50ug / kg); injected once every hour for 8 consecutive injections. During the experimental period, the mice in the three groups were fed the same diet, except that the prevention group ingested 5% (mass of long-chain inulin g / total weight of common mouse feed g) long-chain inulin feed for three consecutive days before injection of cerulein. . Long-chain inulin was purchased from the Netherlands sensus company.

Embodiment 2

[0036] Example 2. Long-chain inulin resists the expression of MPO in pancreatic tissue when acute pancreatitis occurs

[0037] As an important part of the pathogenesis of acute pancreatitis, the activation of white blood cells, especially neutrophils, plays an extremely important role in its pathological process. MPO is a functional marker and activation marker of neutrophils, and its level and activity changes represent the functional and active state of neutrophil polymorphonuclear leukocytes. Myeloperoxidase exists in neutrophils, and the amount of enzyme contained in each cell is certain, accounting for about 5% of the dry weight of the cell. This enzyme has the ability to reduce hydrogen peroxide. Using this feature, it can be analyzed Enzyme activity, and determination of the number of central leukocytes. The principle is as follows:

[0038] MPO+H 2 o 2 → complex; complex + AH 2 (hydrogen donor)→H 2 O+MPO+A product

[0039] The yellow compound is generated after ...

Embodiment 3

[0040] Example 3. Long-chain inulin reduces the level of serum amylase (AMY) when acute pancreatitis occurs

[0041] Existing data show that more than 90% of patients with acute pancreatitis have elevated serum AMY levels, so the present invention detects changes in AMY levels.

[0042] Amylase can hydrolyze starch to produce glucose, maltose and dextrin. When the substrate concentration is known and excessive, add iodine solution and unhydrolyzed starch to form a blue complex. According to the depth of blue, the hydrolyzed starch can be deduced amount, thus calculating the vitality of AMY. Such as figure 1 B, The results showed that the AMY activity of the acute pancreatitis group was significantly higher than that of the normal group, and the AMY activity of the long-chain inulin treatment group was significantly lower than that of the disease group. It can be concluded that the activity of AMY in mice with acute pancreatitis was significantly down-regulated after the prev...

Abstract

The invention discloses effect of long-chain inulin in adjusting acute pancreatitis and related tissue damage caused thereby, and belongs to the technical field of prevention and treatment of acute pancreatitis. It is verified herein that long-chain inulin can protect from caerulein-induced acute pancreatitis in mice and may be added, as an effective ingredient, to drugs for preventing and treating acute pancreatitis, thereby reducing occurrence and progress and degree of clinical acute pancreatitis. The long-chain inulin is used to carry out preventive treatment for a caerulein-induced mice acute pancreatitis model, pathomorphologic observation is carried out on pancreatic tissues of mice, the levels of serum pancrelipase, serum amylase and tissue inflammatory cell liberase in mice are measured, anti-inflammatory cytokine IL10 and pro-inflammatory cytokine TNF-Alpha and IL1 Beta in tissues and serum are also measured. By comparing index levels of mice in an insulin treatment group and an inflammatory model group, the indexes of mice in the inulin treatment group are significantly better those of the inflammatory model group.

Description

technical field [0001] The invention relates to the effect of long-chain inulin on regulating acute pancreas inflammation and related tissue damage caused by it, and belongs to the technical field of prevention and treatment of acute pancreatitis. Background technique [0002] Inulin is a mixture of natural fructans. Fructans are carbohydrates in which fructose units are connected by (2-1) chains and terminated by glucose units, and are contained in the protoplasm of cells in a colloidal form. It is mainly found in Compositae plants, for example, in the tubers of Jerusalem artichoke, the roots of Geranium (Dali Chrysanthemum), and the roots of thistles. Studies have shown that long-chain inulin in the diet can alleviate the symptoms of patients with necrotizing colitis, and a diet low in fermentable oligosaccharides, disaccharides, and polyols can effectively reduce functional gastrointestinal symptoms in patients with irritable bowel syndrome, which shows that long-chain i...
