The study was carried out on 10 male rabbits, New Zealand pure-bred, 3.5 months old, and weighing 2,000-2,200 g. The animals were divided into two equal groups: group 1 - subjected to short term lateral electrical surface stimulation (ST-LESS) for 2 h daily during 3 months, group 2 - control group without LESS stimulation but with other experimental parameters as in animals of the group 1 (SCOL-2 apparatus and preparation the skin to electrostimulation). Stimulation was performed with a Polish stimulator - SCOL-2, and clinical, macroscopic, and microscopic observations were performed. Similar growth of body mass was observed in the rabbits from both groups during the first two months of the experiment. In month 3 a slightly smaller increase in weight gain was observed in the animals from group 1 than in those from group 2. No morphological lesions were observed in a macroscopic examination. A statistically significant increase in the mean mass of the adrenal glands (0.4253 g +0.0033) of the stimulated rabbits in comparison to those from the group 2 (0.2981 g ±0.0087) was noted. A microscopic examination revealed hypertrophy of zona fascicularis with visible overgrowth of glandular cells in the rabbits from group 1. The results of clinical observations as well as morphological lesions indicate the presence of adaptive stress in rabbits stimulated with ST-LESS.
