Information-Thermodynamic Method for the Study of Proliferation of Organized Cellular Structure

The aim of the article was to develop an innovative method for the study of cell proliferation based on the information-thermodynamic approach, including the mathematical ratio-the entropy of cell proliferation and an algorithm for the calculation of fractal dimension of the cellular structure. Approbation of this method with pulsed electromagnetic impact on culture in vitro was implemented. It is shown on the basis of experimental data that the organized cellular structure of juvenile human fibroblasts is a fractal. The method makes it possible to determine the stability of the effect on cell proliferation. The prospects for the application of the developed method are discussed.

Substantiation of the additional prescription of magnetotherapy in the complex of rehabilitation of children with concomitant diseases of the nervous system during remission of cancer

Introduction. The increase in the number of children with oncological diseases requires development of effective methods of medical rehabilitation. Purpose: To determine the effectiveness of the use of low-frequency magnetotherapy (LFMT) in children with diseases of the nervous system, manifested in the period of remission of oncological diseases (OD) in the complex of sanatorium rehabilitation (SRR). Methods: Children with OD at the stage of rehabilitation in a sanatorium underwent a clinical examination: medical history, concomitant pathology, complaints, clinical examination, assessment of neurological status; instrumental studies: electroencephalography (EEG) - assessment of the bioelectrical activity of the brain; echoencephalography (EchoEG) - assessment of CSF dynamics; Doppler ultrasound (USDG) - assessment of cerebral circulation. For 25 children with concomitant diseases of the nervous system during the period of OD remission (17 people) and solid tumors (8 people), in addition to the general complex of SRR, magnetotherapy was prescribed for the cervical-collar zone according to the following method: magnetic induction 20 - 30 mT, exposure 10 - 15 minutes, every other day, for a course of 5 procedures. Results: The use of the therapeutic complex TFR with the additional prescription of magnetotherapy can reliably reduce childrenʹs complaints in remission of the OD for the impaired activity of the nervous system. According to the USDG indicators, statistically significant positive changes in cerebral hemodynamics were established. The results of ultrasound echoEG indicate the improvement of CSF dynamics. According to the EEG data, positive changes in the state of brain electrogenesis were established. Conclusion: The effectiveness of LFMT in children in the period of remission of oncohematological diseases with concomitant diseases of the nervous system has been substantiated.

[Magnetotherapy in patient rehabilitation after radical mastectomy]

OBJECTIVE

Compare the efficacy of low-frequency low-intensity magnetotherapy and fluxtuorization of the shoulder belt and upper limb muscles on the side of surgical intervention in combination with therapeutic exercise and balance therapy, classes in a medical psychologist in patients for 2-4 days and 1.5-2 months after the radical mastectomy.

MATERIAL AND METHODS

A total of 131 patients aged 25 to 70 years were examined and treated after a radical mastectomy for breast cancer. The 1st group included 76 patients who were rehabilitated on the 2nd-4th day after radical mastectomy, the 2nd group included 55 women who were rehabilitated after 1.5-2 months.

RESULTS AND CONCLUSION

It has been established that the early onset of medical rehabilitation in patients after radical mastectomy (on the 2nd-4th day after surgical intervention) contributed to the reduction of pain syndrome and postoperative edema, increase of movements in shoulder joint, prevention of severe lymphostasis and improvement of life quality. The contribution of low-frequency low-intensity magnetotherapy to the complex of rehabilitation measures is, above all, to reduce swelling and reduce blood viscosity. Fluctuating currents promote restoration of volume of movements on the party of operative intervention, namely - support functional activity of muscles and joints of the top extremity that allows to restore a motor stereotype.
