Numerous Soviet and foreign scientists have studied the flora of the medicinal leech. And they found that the insides of medicinal leeches have symbiotic bacteria, which plays a major role in the digestion of proteins, fats and carbohydrates. A detailed study of the properties of symbiotic bacteria of the medicinal leech has shown that it is the bearer of anticoagulant activity. That symbiotic bacteria has a healing effect on the majority of living organisms, which are knowingly or unknowingly become a victim of the medicinal leech. It was the year after year, decade after decade passed. Scientists continue to investigate the leech. And once they found that mysterious substance inside the leech that is produced by bacteria and prevents blood clotting, along with saliva also involved in maintaining the liquid sucked blood. It was found that blood, if it is removed from leech intestinal not coagulate even after prolonged storage. Intestinal microflora of the medicinal leech prevents rotting blood due to their special properties. As a consequence, the question arises: can leech, in this case, to keep within themselves and all kinds of viruses, dangerous to the health of living beings? Then the scientists decided to conduct an interesting experiment. Inside leeches were placed pathogens. As a result of this experiment showed that due to the bactericidal action of the digestive tract leeches reduced ability of pathogenic organisms remain viable. For example:
causative agents of typhoid stored inside the leech 30 days;
paratyphoid B – 4 months;
anthrax – 14-17 days;
TB – 28 days;
Staphylococcus aureus – 3-10 days.
Similar studies are ongoing by scientists to this day. Much remains unknown, there are more and more questions. For example, as a result of such experiments have a question, very important for those involved or just going to seriously engage hirudotherapy: “Is there a risk of transmission of pathogens leeches from one animal or person to another?” Opgty showed that this happens only if the infected leech after living object immediately put healthy. Do not worry, future-doterapevty Gere and those who decided to try to do recovery and put leeches on their own at home. Scientists have also found that when the interval between feedings daily to patients and healthy animal pathogen is not transmitted. But research on AIDS and hepatitis has not been done, so as to avoid infection with these diseases, it is necessary to use only certified medical leech.Currently, scientists are not well known what is happening inside the digestive tract leeches, what is the specificity of enzymes that are contained in it. There is a view that the enzymes digestive tract leeches are directly related to the metabolism of serotonin. A serotonin, known to be a substance, the lack of which in the human body leads to a number of physical and often mental disorders. Many doctors believe that it is the lack of serotonin causes the alcohol, drug abuse and psychopathology.
