Research of Prof. Krashenyuk
Research publications, observations and theses of prof. A. I. Krashenyuk
Over several decades, Professor A. I. Krashenyuk, PhD, together with his collaborators, developed a systemic approach to hirudotherapy. His research topics, clinical observations and theoretical models have been presented in professional proceedings, at conferences and congresses, and in individual scientific and professional publications.
The following overview summarises the authors' premises, research hypotheses and observations relating to the systemic approach to hirudotherapy.
1. Hirudobiopsy
In 1992, prof. A. I. Krashenyuk and S. V. Krashenyuk described a phenomenon which they termed hirudobiopsy. As part of their observations, they investigated the possibility that, following the application of medicinal leeches, biological materials are released from the body which could be of relevance for further laboratory analysis.
This approach was presented as a research hypothesis on the possible diagnostic value of the processes observed during hirudotherapy.
2. The phenomenon of biochemical adaptation
The phenomenon of biochemical adaptation is one of the central concepts of the systemic approach to hirudotherapy. The authors proposed a gradual adaptation of the organism to the components of the medicinal leech's secretion through the use of a small number of leeches and carefully selected application sites.
Within this theory, gradual adaptation is supposed to influence the local responses of the skin and tissues following application. The concept is presented as the authors' own model, which requires further research and does not constitute a guarantee that adverse responses cannot occur in an individual.
3. The energetic or informational effect of hirudotherapy
In studies presented in the 1990s, the authors examined changes in measurements before and after hirudotherapy using the Akabane test, bioelectrographic methods and other approaches.
On the basis of these observations, they developed the concept of an energetic or informational-entropic effect of hirudotherapy. This model addresses possible changes in the organism's regulatory processes, but is not intended for establishing medical diagnoses.
4. The neurotrophic and neuronal stimulatory effect
Prof. Krashenyuk and his collaborators investigated the influence of medicinal leech components on the growth of nerve fibres in tissue culture. A Russian patent, relating to the stimulation of nerve fibre growth in a culture of chick embryo ganglia, was obtained for modelling this effect.
The authors associated the neurotrophic effect with certain components of the medicinal leech's secretion, among them destabilase, bdellins and bdelastasin. These are preclinical research findings, which cannot be directly equated with a confirmed clinical approach in neurological diseases.
5. The acoustic or wave effect of the medicinal leech
In collaboration with D. I. Frolov, prof. Krashenyuk investigated the phenomenon of acoustic emission by the medicinal leech during feeding. The authors described ultrasonic signals in the frequency range from approximately 25 to 250 kHz and proposed that these signals might be involved in the interaction between the leech and the organism.
This concept represents a research model for understanding possible physical processes in hirudotherapy and remains the subject of further research.
6. The concept of integral blood toxicity
In 2003, prof. Krashenyuk presented a concept according to which the condition of the medicinal leeches after application could serve as an indicator of certain properties of the blood or of the processes of substance elimination from the organism.
The concept arose from long-term monitoring of an individual case and was presented as a research observation. It does not constitute a standardised laboratory method for determining toxins or health status.
7. Local hyperthermia in neurinoma
Prof. Krashenyuk and Yu. F. Kamynin described a clinical case involving long-term monitoring of a person with a neurinoma. As part of the observation, they tracked temperature changes in the area of the lesion and proposed an explanation concerning a possible influence of local hyperthermia.
This is a description of an individual clinical case, which cannot be understood as proof of the general efficacy of hirudotherapy in tumours, or as a substitute for oncological and neurological treatment.
8. The negentropic effect of hirudotherapy
In collaboration with G. N. Dulnev, prof. Krashenyuk developed the concept of a negentropic effect, related to the relationship between order and chaos in biological systems.
The authors proposed that hirudotherapy could influence the organism's regulatory processes and the establishment of internal balance. This is a theoretical model, which remains the subject of further research.
9. The water-structuring effect
In 2010, L. P. Semihina and A. I. Krashenyuk presented research findings on possible changes in the structure of water in tissues during the feeding of the medicinal leech.
The study was associated with observations on an animal model and with the use of dielectric measurements. The authors proposed that changes in the tissue water system could contribute to the understanding of certain processes in hirudotherapy.
10. The neurotransmitter effect
In later publications, prof. Krashenyuk presented research observations on a possible influence of hirudotherapy on processes related to neurotransmitters.
The author described changes in the measurements of serotonin, acetylcholine, noradrenaline, GABA, enkephalins and other signalling molecules. These results represent a research hypothesis and do not constitute a clinically confirmed method for regulating neurotransmitters.
Important professional notice
This text summarises the research publications, professional observations and theoretical models of prof. A. I. Krashenyuk and his collaborators. Individual theses and interpretations are still the subject of further research and do not constitute generally accepted clinical guidelines.
Hirudotherapy does not replace a medical examination, diagnostics, prescribed treatment or emergency medical care. The suitability of an individual treatment is always assessed on an individual basis, taking into account the state of health, medications and contraindications.
