实验性短期电刺激引起的机体紊乱
Objective To determine the effect of LESS-st on the organism of developing rabbits,and provide reference for the treatment of idiopathic scoliosis.Method Investigations were carried out on 10 rabbits, males, 3,5 months, New Zealand race, divided into two equal groups (n = 5): I -in which short-timed lateral electric surface stimulation (LESS-st) was applied for 2 h daily during 3 months, II -control group, where animals were not stimulated. LESS was performed with SCOL-2, a Polish stimulator, which was placed to the right of the rabbit spine, according to the method modified by Kowalski. After 3 months the animals were sacrificed, and macroscopic examination was performed. Statistical analysis based on Student's t-test was carried out into account body mass and results of the macroscopic evaluation.Result Post mortem examination of the internal organs showed no pathologic lesions in the animals both group. Only mean mass of suprarenes in electrostimulated rabbits was 42.7 % bigger than in control ones.The obtained results suggest that LESS-st did not cause statistically significant disturbances of rabbit growth during a 3-month experiment. Small variations were observed only in the end phase of the investigation.Conclusion (1) Short-timed electrostimulation (2h/day) did not cause statistically significant disturbances of rabbit growth during a 3-month experiment.(2) Short-timed LESS resulted in some behavioural disturbances in rabbits.
