Abstract

OBJECTIVE: To compare the effect of decimeter wave with sodium hyaluronate product (SHP) on preventing and treating peritendinous adhesion and promoting tendon healing.

METHODS: Totally 96 healthy male white 6-month-old Leghorn chickens weighing (2.24 +/- 0.07) kg were randomized into group A (decimeter wave therapy group, n = 32), in which decimeter wave therapy was applied 1 to 21 days after operation at a frequency of 915 MHz, a power of 8 W, radiation distance of 10 cm, for 10 minutes once per day; group B (SHP group, n = 32), in which 5 mL and 1.2% SHP was applied; and group C (control group, n = 32), in which injury received no treatment. The III and IV toes of left feet of all chickens were made into tendon injury model. The general condition of animal was observed after operation; gross and histological observations were made 7, 10, 14, 18, 21 and 28 days after operation, and the biomechanical analysis was done 14 and 28 days after operation.

RESULTS: Operative incision healed well, no infection and death occurred. Peritendinous adhesions in groups A, B were looser, and tendon healing was better than that of group C 14 and 28 days after operation. More fibroblasts with active metabolism and more collagen formation in groups A, B than that in group C. The Pmax of group A was better than that of group B 14 and 28 days after operation (P < 0.05); the delta max of group A was better than that of group B 18 and 21 days after operation (P < 0.05), and the W0 of group A was better than that of group B 18, 21 and 28 days after operation (P < 0.05). There was no significant difference between group A and group B at the other time points.

CONCLUSION: Topical decimeter wave therapy and application of SHP after flexor tendon repair can promote intrinsic healing, meanwhile they can prevent the adhesion of tendon and reduce extrinsic healing. Decimeter wave therapy can improve the qualities of tendon’s wound healing.

Decimeter-wave physiotherapy in viral hepatitis.

[Article in Russian]

Kents VV, Mavrodi? VM.

Abstract

Effectiveness was evaluated of magnetotherapy, inductothermy, UNF electric field and electromagnetic waves of decimetric wave band (460 MHz) on the projection of the liver, adrenals and thyroid gland in controlled trials enrolling a total of 835 patients with viral hepatitis (type A, B, associated forms). A conclusion is reached that optimum effectiveness of decimetric field on the projection of the adrenals and thyroid gland can be achieved through the application of minimum power and everyday alternation of exposures. It has been estimated that as many as 69 percent of the patients derive benefit from the above treatment.

Changes in intracellular regeneration and the indices of endocrine function and cardiac microcirculation in exposure to decimeter waves.

[Article in Russian]

Korolev IuN, Geniatulina MS, Popov VI.

Abstract

An electron-microscopic study of rabbit heart with experimental myocardial infarction revealed that extracardiac exposure to decimetric waves (DW) activated intracellular regeneration in the myocardium. This was associated with enhanced circulation and endocrine activity in the heart. Most pronounced regeneration was registered in adrenal exposure, the effect of the parietal exposure being somewhat less.

[Article in Russian]

Frenkel’ ID, Zubkova SM, Liubimova NN, Popov VI.

Abstract

Biochemical and morphometric methods were employed to study the effect of decimetric waves (460 MHz, 10 and 120 mW/cm2) in cardiac and thyroid exposure on oxygen metabolism, myocardial microcirculation and contractility, thyroid and adrenal hormonal activity, kallikrein-kinin system activity in rabbits with experimental myocardial ischemia. Hypoxia discontinued in all the treatment regimens, but the exposure of the heart (field density 10 mW/sm2) had the additional effect on lipid peroxidation which reduced in the serum and normalized in the myocardium, on myocardial contractility, kallikrein-kinin system and on the adrenal and thyroid hormones.

The combined action of an ultrahigh-frequency electrical field bitemporally and decimeter waves on the thymus area in the combined therapy of rheumatoid arthritis patients.

[Article in Russian]

Sidorov VD, Grigor’eva VD, Pershin SB, Bobkova AS, Korovkina EG.

Abstract

The thymus of rheumatoid arthritis (RA) patients was exposed to combined action of bitemporal UHF electric field and decimeter waves to study immunomodulating effect of the combination. Biochemical, immunological and endocrinological findings during the patients follow-up gave evidence for conclusion on activation of the hypothalamic-hypophyseal-thymic axis. A response was achieved in RA seronegative variant with concomitant synovitis. This may be due to genetic factors.

The immunological and hormonal effects of combined exposure to a bitemporal ultrahigh-frequency electrical field and to decimeter waves at different sites.

[Article in Russian]

Sidorov VF, Pershin SB, Frenkel’ ID, Bobkova AS, Korovkina EG.

Abstract

Bitemporal UHF electric field is shown to enhance glucocorticoid adrenal function unlike inhibition of the thyroid function suppressing a primary immune response (PIR) in the productive phase. The combined exposure to bitemporal UHF electric field and decimeter waves of the adrenals doubles glucocorticoid synthesis abolishing the inhibitory action of the UHF therapy on thyroid function resultant in much more suppressed PIR. Both modalities inhibit thymic production. Decimeter waves alone are less effective. The exposure of the thyroid to decimeter waves initiated PIR by 2.5-fold activation of medullar lymphocytes and by a 80% increase in the thymic function. No response was achieved in combined action on the thyroid of the electric field and decimeter waves.
