                      2019-12-18 20:46

                      腸道是人體的重要器官之一,它的主要作用就是幫助人體進行食物消化和營養吸收。同時他還有一個重要的功能就是守護人體健康,為我們提供一道重要的免疫屏障,而真正行使這些具體的功能不只是腸道本身,更多的是靠腸道內寄居的數量眾多的微生物來完成的,這些微生物與腸道一起打造出一套腸道微生態系統,來共同完成,諸如免疫,營養供給等作用

                      在我們們腸道內眾多的微生物群體可以大致分為三類,益生菌,中性菌以及致病菌,而足夠量的益生菌是才是真正幫助我們維護健康的菌落,這個菌落成員眾多,其中包括雙歧桿菌屬、乳桿菌屬、腸球菌屬和酵母菌屬等。

                      益生菌在我們體內起到的主要作用包括一下幾點:

                      1、維護腸道菌群平衡

                       益生菌對腸道菌群的調節機制歸納起來主要有以下幾個方面:

                      生物拮抗。益生菌就其種類而言,一般為腸道的優勢菌群。在進入腸道以后,會迅速繁殖并且與其他有害生物競爭營養和所粘附的黏膜空間,同時也會主動分泌抗菌物質,如抗生素、過氧化氫等,造成其他有害生物生長受阻。

                      改變腸道pH值。益生菌在其生長過程中,大部分種類都會發酵產生乳酸,而這些乳酸能有效降低腸道pH值,從而抑制部分無法耐受酸性環境的有害微生物。

                      恢復腸黏膜。益生菌具有保護腸黏膜,減輕腸黏膜炎癥以及輔助恢復腸黏膜的功能。

                      2、提高人體免疫力

                         益生菌對免疫系統的調節機制較為復雜,但其核心在于可以刺激宿主的免疫應答,增強體液免疫及細胞免疫,從而增加機體免疫力。

                      益生菌在腸道疾病預防和治療過程中應用比較廣泛, 其中主要應用領域包括以下幾點:

                      1.應用于腹瀉輔助治療:

                          腹瀉根據其病因通??煞譃槟c道病原微生物或寄生蟲感染、消化系統功能性或器質性疾病、代謝性疾病、自身免疫性疾病、放射性腸炎、抗生素導致腸道菌群紊亂等。但不論何種原因引起的腹瀉,均不可避免地造成腸道菌群的嚴重紊亂。因此,臨床上對于腹瀉的治療,益生菌已成為重要的輔助治療手段,在恢復腸道菌群的平衡中起重要作用。

                      2.改善腸道微環境,調理便秘:

                          便秘對于人體的傷害很大,是一件很痛苦的事,同時便秘患者由于糞便長時間在腸道里積累,還易誘發腸道腐敗菌的繁殖而造成毒素的沉淀?,F在治療便秘的方法有很多,通常常用的做法包括服用瀉藥、促腸動力藥、灌腸等,而根據最新研究發現便秘患者腸道菌群與健康人群同樣有著很大差別。這種菌群的差別也極有可能是造成人體便秘的一種原因。所以不管怎樣,便秘患者在其他手段以外都要對于腸道菌群調節和恢復重視起來,而益生菌也確實可以幫助我們有效改善腸道微環境、維護腸道菌落平衡以及促進腸道蠕動。

                      3.炎癥性腸病輔助治療

                           炎癥性腸病是一類慢性腸道炎癥性疾病,包括潰瘍性結腸炎和克羅恩病等。主要癥狀有腹瀉、腹痛和腸道不適。目前該病的發病機制通常認為與遺傳因素、免疫因素、環境因素有關。因此,炎癥性腸病的治療時可以從調理腸道菌群、消除腸道炎癥入手。目前,臨床上多采用在傳統治療的基礎上添加益生菌,將益生菌作為輔助治療進行應用。

                      隨著各界對于益生菌的功用的不斷研究和開發,益生菌可應用領域范圍也在不斷拓寬,包括目前我們認為比較棘手的腸道腫瘤,都與我們腸道內的菌群有著相應的關系,未來益生菌被應用于這類疾病的預防和治療也是有著極大的可能,讓我們共同期待益生菌的應用為我們開啟新的健康之門。

                      Intestinal tract is one of the important organs of human body. Its main function is to help human body digest food and absorb nutrition. At the same time, it also has an important function to protect human health and provide us with an important immune barrier. The real exercise of these specific functions is not only the intestinal tract itself, but also depends on the large number of microorganisms living in the intestinal tract. Together with the intestinal tract, these microorganisms create a set of intestinal micro ecosystem to complete together, such as immunity and nutrition Supply and other functions

                      There are three kinds of microbial groups in our intestines: probiotics, neutral bacteria and pathogenic bacteria, and enough probiotics are the colonies that really help us maintain health. There are many members in this colony, including bifidobacteria, Lactobacillus, Enterococcus and yeast.

                      The main functions of probiotics in our body include the following:

                      1. Maintain the balance of intestinal flora

                      The regulatory mechanism of probiotics on intestinal flora can be summarized as follows:

                      Biological antagonism. Probiotics are generally the predominant flora in the intestine. After entering the intestinal tract, it will propagate rapidly and compete with other pests for nutrition and the mucosal space adhered to. At the same time, it will also actively secrete antibacterial substances, such as antibiotics, hydrogen peroxide, etc., which will hinder the growth of other pests.

                      Change intestinal pH. During the growth process of probiotics, most kinds of probiotics will ferment to produce lactic acid, which can effectively reduce the pH value of intestinal tract, thus inhibiting some harmful microorganisms unable to withstand the acid environment.

                      Repair intestinal mucosa. Probiotics have the functions of protecting intestinal mucosa, alleviating inflammation of intestinal mucosa and assisting in repairing intestinal mucosa.

                      2. Improve human immunity

                      The regulation mechanism of probiotics to the immune system is complex, but its core is to stimulate the host's immune response, enhance humoral and cellular immunity, and thus increase the body's immunity.

                      Probiotics are widely used in the prevention and treatment of intestinal diseases, including the following main application areas:

                      1 for the treatment of diarrhea:

                      Diarrhea can be divided into intestinal pathogenic microorganism or parasite infection, functional or organic diseases of digestive system, metabolic diseases, autoimmune diseases, radiation enteritis, and intestinal flora disorder caused by antibiotics. However, no matter what causes diarrhea, it will inevitably cause serious disorder of intestinal flora. Therefore, probiotics have become an important auxiliary treatment for diarrhea, and play an important role in restoring the balance of intestinal flora.

                      2. Improve intestinal microenvironment, regulate constipation:

                      Constipation does great harm to human body, which is a very painful thing. At the same time, due to the accumulation of feces in the intestinal tract for a long time, constipation patients are easy to induce the reproduction of intestinal spoilage bacteria, resulting in the deposition of toxins. Now there are many ways to treat constipation, including taking cathartic, enema, etc. according to the latest research, the intestinal flora of patients with constipation is also very different from that of healthy people. This kind of flora difference is also likely to be a cause of human constipation. In any case, the patients with constipation should pay attention to the regulation and recovery of intestinal flora in addition to other means, and probiotics can help us effectively improve the intestinal microenvironment, maintain the balance of intestinal flora and promote intestinal peristalsis.

                      Adjuvant treatment of inflammatory bowel disease

                      Inflammatory bowel disease is a kind of chronic intestinal inflammatory diseases, including ulcerative colitis and Crohn's disease. The main symptoms were diarrhea, abdominal pain and intestinal discomfort. At present, the pathogenesis of the disease is generally considered to be related to genetic factors, immune factors and environmental factors. Therefore, the treatment of inflammatory bowel disease can start from regulating intestinal flora and eliminating intestinal inflammation. At present, probiotics are usually added on the basis of traditional treatment, and probiotics are used as auxiliary treatment.

                      With the continuous research and development of probiotics from all walks of life, the scope of application of probiotics is also expanding, including the intestinal tumors that we think are more difficult at present, which have a corresponding relationship with the flora in our intestines. It is also possible for probiotics to be used in the prevention and treatment of such diseases in the future. Let's look forward to the application of probiotics Open a new door to our health.
