[우리문화신문=유용우 한의사] The advantages and disadvantages of oriental medicine are clearly revealed, and the treatment methods and prescriptions of oriental medicine doctors are white and white (百人百色). On the one hand, this becomes a weakness and leads to the limit of communication with each other, and on the other hand, it becomes an advantage, creating a treatment method that overcomes the limitations of general treatment.
Through treating children and encountering rhinitis patients, he recognized a diversity in the causes and treatments for rhinitis. Nevertheless, it is the condition of the large intestine that the author sees as the biggest factor in the disease from the time of his oriental medical student and early oriental medical doctor to the present day. In other words, the large intestine is the most important core when looking at diseases, and removing waste that starts from the large intestine is my color.
For children, rhinitis is treated by unblocking the stagnation of the terminal circulation from the fingertips, toes, and tip of the nose in conjunction with the stagnation of the large intestine. Rhinitis is treated by removing the pressure caused by the rhinitis. This means that the function of the large intestine is important. In addition, this is because if there is a burden or imbalance in the digestive tract, it is accumulated and manifested in the large intestine, which is the end of the digestive tract.
So, today, we would like to learn about the functions and characteristics of the large intestine, and take time to learn about the general physiological functions of the large intestine and the bacterial fermentation process, which is the unique environment of the large intestine.
1. General Physiological Functions of the Large Intestine
The digestive system consists of long tubes that run throughout the body. Food that starts in the mouth, passes through the esophagus, and stays in the stomach for a while is digested and absorbed in the small intestine with the help of bile and pancreatic secretions in the duodenum. After digestion and absorption, the leftover food remains are released from the body in the state of feces (大便) after absorbing water and minerals in the large intestine.
The gastrointestinal tract of a living person is 450 cm long from the mouth to the anus. Among them, the length of the small and large intestine is 395 cm, and the small and large intestines occupy a very large proportion in the digestive system. The intestine, which includes the small intestine and the large intestine, is where food from the outside is digested and absorbed directly, and also where faeces are produced. Therefore, the functions of the small intestine and large intestine are the most important for good bowel movements.
The large intestine is a very important organ that supplies water to the human body because it absorbs 1.5~2L of water and salt from the waste that is digested and absorbed in the small intestine. The state of the contents of the large intestine (decay, fermentation, harmful substances, etc.) greatly affects the water absorbed from the large intestine, and the water and electrolyte absorption process determines the state of the stool
It is generally known that food is not digested in the large intestine, but in fact, indigestible carbohydrates and proteins are fermented and broken down by a number of intestinal bacteria present in the large intestine. And organic acids (fatty acids) such as lactic acid or butyric acid produced in this process are used as energy sources in colon cells. In addition, various vitamins, including vitamin K synthesized by intestinal bacteria, are absorbed and used in the large intestine.
In other words, the large intestine not only absorbs water and salt, but is also a place where the synthesis and digestion of nutrients necessary for the human body with the help of intestinal bacteria takes place.
* Functions of the large intestine
1. Through fermentation, it produces the last net exhaust component obtainable from food.
2. Absorbs moisture and various vitamin components.
3. Faeces excreted by proper bowel movement.
4. Forms intestinal flora and improves immunity through fermentation.
2. The function of the large intestine is achieved through the fermentation environment called bacteria, which is an external aid.
1) Intestinal bacteria and lactic acid bacteria
There are around 500 types of intestinal bacteria living in our intestines, and the number of bacteria is known to reach around 100 trillion. There are approximately 1,000 intestinal bacteria per 1 g of intestinal contents, and most of these bacteria reproduce through food that comes from outside and nutrients that are released from the body. Soon, some of the food we eat is used for the multiplication of intestinal bacteria, and the multiplied intestinal bacteria is excreted through feces.
Enterobacteriaceae were first discovered by a Dutch scientist, Leewenhoek, and Pasteur was the first person to discover lactic acid bacteria after the discovery of intestinal bacteria. And Elie Metchinikoff, who won the Nobel Prize for his ‘life extension’ thesis, proved that lactic acid bacteria, which are beneficial bacteria present in the gut, replace putrefactive intestinal microbes. He is the first scholar to explain the relationship between intestinal rot and aging by introducing the concepts of putrefactive and beneficial bacteria in the intestine while emphasizing the need for lactic acid bacteria and the secret of longevity.
Recently, enteric bacteria are receiving new attention as they use lactic acid bacteria to see good therapeutic effects for irritable bowel syndrome, allergic diseases, and atopic dermatitis. We need to go beyond blind faith and simply understand the process of how the gut microbiota living in the gut affects these diseases. And if you actively use it for the treatment of atopic diseases, including atopic dermatitis, based on your understanding of intestinal bacteria, you will see better effects.
2) Dietary fiber is the core of the intestinal flora
Dietary fiber not only increases the bulk of the stool by absorbing water, but also affects the intestinal bacteria that make up the stool. Dietary fiber multiplies lactic acid bacteria that are beneficial to the human body and, as a result, increases the number of bacteria in the intestine, thereby increasing the amount of excretion. In addition, dietary fiber that is broken down by intestinal bacteria is absorbed into the body and activates the immune system.
Ultimately, if the amount of lactic acid bacteria beneficial to the human body is increased by eating enough dietary fiber, not only does the size of the stool increase, but so does the number of lactic acid bacteria lactic acid increases, thereby maintaining the balance of intestinal bacteria, which has a beneficial effect on health.
3. Enterobacteriaceae, providing various functions
It is believed that there are more enzymes in the gut bacteria than in the liver in our body. Therefore, it is expected that the substances produced by the intestinal bacteria will vary significantly, and the effects on the human body will also appear to be varied.
Intestinal bacteria infected from the outside after birth form a symbiotic relationship with our body and stimulate the body’s immunity. Enterobacteriaceae stimulate the intestinal wall, causing the immune system to produce antibodies such as immunoglobulin G (IgG) and immunoglobulin A (IgA). In addition, intestinal bacteria help vitamin K synthesis, protein synthesis, and increase the acidity of the colon, thereby helping the absorption of calcium, magnesium and zinc. It is also closely related to intestinal function, such as protecting the human body from pathogenic microorganisms and increasing intestinal motility.
1) Remove harmful substances
Food and drugs that enter the mouth are affected by intestinal bacteria in the process of digestion and absorption and are converted into various substances. Among these substances, there are many harmful substances that harm the human body, such as causing cancer or accelerating aging.
Lactobacillus in the intestine not only prevents the production of harmful substances by harmful bacteria, but also protects health by preventing absorption in the body. In addition, acetic acid, lactic acid, and propionic acid produced by lactic acid bacteria are used as a source of energy for the human body and at the same time protect intestinal cells from harmful substances.
2) Strengthen the immune system
The intestinal bacteria act to activate the immune function. Experiments using sterile animals showed that compared to normal animals, the development of the lymphatic system, an immune organ that protects the human body, is poor in sterile animals. In other words, enterobacteriaceae act on intestinal-related lymphoid tissues to stimulate the differentiation of B lymphocytes, and activate T lymphocytes, macrophages, and neutrophils to improve immune function.
In addition, lactic acid bacteria increase the production of immunoglobulin A antibodies in the intestinal mucosa and inhibit harmful bacteria. In addition, a glycoprotein component called peptidoglycan, which forms the cell wall of lactic acid bacteria after death, is absorbed into the digestive tract and activates macrophages (a unique cell that eats waste or dead cells) , thereby improving immune function.
In addition, research results continue to be reported that lactic acid bacteria can prevent allergies by breaking down antigens in food. For this reason, the use of lactic acid bacteria in the study of allergies and atopic diseases continues to increase.
3) prevent constipation
Constipation is caused by meat, processed foods, lack of fiber, lack of exercise, and stress. If the stool remains in the intestine for a long time due to constipation, it is decomposed by harmful bacteria and a large amount of harmful substances such as ammonia and hydrogen emulsification are produced, which can cause colon cancer or various diseases.
Lactobacillus produces lactic acid and acetic acid to prevent the growth of harmful bacteria. In addition, it prevents and absorbs the production of harmful substances to reduce the incidence of diseases including colon and rectal cancer, and lactic acid, propionic acid, and acetic acid stimulate the intestine to prevent constipation. In addition, dietary fiber helps the proliferation of lactic acid bacteria and increases the number of feces to facilitate bowel movements.
4) It has a profound effect on skin beauty
Harmful substances produced by harmful bacteria can cause various diseases when absorbed into the body. For example, when various harmful substances absorbed into the body act on the skin, symptoms such as skin problems occur. Lactobacillus produces Bacteroicin (a natural antibiotic that kills other bacteria), a substance that inhibits other bacteria. This substance not only reduces the production of harmful substances by inhibiting harmful bacteria in the intestine, but also acts on acne bacteria on the skin to treat skin It can be useful.
5) nutrient supply
Lactobacillus synthesizes beneficial nutrients such as vitamin K (involved in blood clotting), vitamins B1, B2, B6, B12, folic acid, nicotinic acid, lactic acid, acetic acid, butyric acid, and propioic acid. It helps to digest and absorb food by producing digestive enzymes such as In addition, it has the functions of preventing harmful bacteria, reducing blood cholesterol, improving cirrhosis of the liver, and relieving lactose intolerance (the phenomenon of being unable to digest milk when eat milk because there is no enzyme that breaks down lactose in milk).
