Срыв адаптационных возможностей организма может стать патогенетической основой различных заболеваний. Длительный выброс адреналина в кровь вызывает кататоксические эффекты, что делает актуальным поиск эффективных средств и методов коррекции гиперадреналинемии. Цель работы - изучение влияния низкоинтенсивного лазерного излучения (НИЛИ) на электрофоретическую подвижность эритроцитов, процессы липопероксидации и структуру надпочечников при адреналовой токсемии у крыс. Методика. Адреналовую токсемию моделировали внутрибрюшинным введением адреналина-гидрохлорида (0,1 мг/кг). Животным 1-й группы вводили только адреналин, животных 2-й - через 30 мин после введения адреналина облучали НИЛИ, крысы 3-й группы получали только воздействие НИЛИ, контролем служили интактные животные (4-я группа). Воздействие НИЛИ проводилось на затылочную область в течение 10 мин. В качестве источника излучения применяли аппарат лазерный терапевтический «Успех» (ГП «Восход»), основанный на низкоинтенсивном импульсном излучении (длина волны - 0,89±0,05 мкм, частота импульсов 415 Гц, плотность средней мощности излучения - 193 мкВт/см2, площадь облучаемой поверхности 20 см2). Забор крови производили через 1 ч, 24 ч и 1 нед после начала эксперимента. Определяли уровень малонового диальдегида по реакции с тиабарбитуровой кислотой; электрофоретическую подвижность эритроцитов изучали методом микроэлектрофореза. Структуру надпочечников изучали морфологическими методами. Результаты. Показано, что НИЛИ на фоне адреналина (2-я группа) через 1 нед нивелировало снижение электрофоретической подвижности эритроцитов, восстанавливало уровень малонового диальдегида до значений интактной группы. Морфологическая картина надпочечников в этой группе не отличалась от таковой у интактных животных, тогда как при действии адреналина (1-я группа) не происходило восстановления исследуемых показателей до физиологической нормы. Заключение. Полученные в ходе эксперимента данные свидетельствуют о корригирующем действии низкоинтенсивного лазерного излучения при адреналовой токсемии у животных. Механизм действия низкоинтенсивного лазерного излучения, вероятно, носит системный характер и связан с воздействием на стресс-реализующие системы организма. Maladaptation results in the third stage of stress, exhaustion, and, thus, may underlie many diseases. Prolonged release of epinephrine into blood exerts catatoxic effects; therefore, searching for effective methods for correction of hyperadrenalinemia is relevant. Presently, low-intensity laser therapy (LILT) is commonly used in medicine. However, the introduction of LILT to clinical practice is largely empirical. The aim of this study was to analyze the effect of LILT on electrokinetic potential of red blood cells (RBC), lipid peroxidation (LPO), and the morphology of adrenal glands in adrenal toxemia in rats. Methods. Adrenal toxemia was modeled by intraperitoneal administration of epinephrine hydrochloride (0.1 mg/kg) to rats. Animals of group 1 received epinephrine alone; animals of group 2 received LILT 30 min prior to epinephrine administration; rats of group 3 received LILT alone; and intact rats of group 4 were used as control. Blood was withdrawn at one hour, 24 h, and one week of the experiment onset. The RBC zeta potential, which characterizes the morpho-functional state of membranes, was determined by measuring the effect of low-intensity laser therapy on RBC electrophoretic mobility using microelectrophoresis. LPO as an indicator of cell membrane injury was determined by concentration of malonic dialdehyde (MDA). The structure of adrenal glands was studied histologically. Results. LILT combined with epinephrine (group 2) alleviated the decrease in RBC electrophoretic mobility and restored the MDA level to values of the intact group at one week. Morphological structure of adrenal glands in group 2 did not differ from that in control whereas epinephrine (group 1) did not restore the study parameters to physiologically normal values. Conclusion. The study showed that LILT exerted a correcting effect in experimental adrenal toxemia. The mechanism of this effect is likely systemic and related with the effect on stress systems of the body.

Introduction. The effect of laser irradiation on the body can lead to local tissue damage, which will be accompanied by changes in biochemical processes that occur in the kidneys. The direction of these changes is completely unclear, so the study of free radical oxidation of lipids and proteins as the main markers of oxidative stress in the body and their correction by ω-3 polyunsaturated fatty acids (PUFA) remains relevant. Aim.  To evaluate the intensity of lipid peroxidation and oxidative modification of proteins in the postnuclear fraction of rat kidneys under the action of laser irradiation and additional administration of ω-3 PUFA. Methods. The studies used white outbred rats, which were irradiated daily for 4 minutes with a laser diode with a wavelength of 650 nm, power of 50 mW in the abdominal cavity at a distance of 10 cm from the skin surface. The state of lipid peroxidation (LPO) was determined by the level of primary, secondary and final products. The intensity of oxidative modification of proteins (OMP) was evaluated by the level of carbonyl derivatives and protein SH-groups. To correct the prooxidant state, the animals were additionally injected with ω-3 PUFA. Results. Low-intensity laser irradiation has a destructive effect on the cell membranes of the kidneys, which is expressed by an increase in primary, secondary and final products of LPO in phospholipid extracts and an increase in the intensity of OMP. The introduction of ω-3 PUFAs reduces free radical processes in the kidneys of irradiated rats, but this effect depends on the scheme of their introduction. ω-3 PUFAs do not show antioxidant effect under the conditions of their introduction after laser irradiation. Daily administration of ω-3 PUFA two hours before irradiation shows a slight antioxidant effect only in the initial stages of irradiation. Preliminary seven-day administration of ω-3 PUFA before laser irradiation is the most effective, as it helps to reduce free radical processes. Conclusion. It is established that ω-3 PUFAs are able to have a corrective effect on the action of low-intensity laser irradiation, which depends on the scheme of their introduction. The highest antioxidant effect is observed in groups of animals to which ω-3 PUFA was previously administered before the action of laser irradiation.

Experimental Group

The effect of low-intensity laser radiation on the biochemical, immune and clinical status of calf-malnutrition was studied. The studies were carried out in 2 groups (experimental and control) for 12 animals with symmetric hypotrophy 2 (medium) severity. The calves of the experimental group underwent irradiation of blood with low-intensity laser radiation in the red spectral range (wavelength 630 nm). The animals of the control group were not treated (intact). Clinical observations of the calves were conducted for 2 months, taking into account the incidence, duration and severity of the disease, as well as weight gain. Blood sampling for biochemical and immunological studies was performed on the 1st and 21st days of life. Treatment of animals with low-intensity laser radiation positively affected their clinical state and productivity. Calves of the experimental group compared with the control were ill with gastrointestinal diseases in mild form with shorter duration of their course, and weight gain was significantly higher. The positive effects of low-intensity laser radiation on biochemical status, natural resistance and clinical condition of hypotrophic calves have been established, which allows us to recommend it for their rehabilitation.

It is shown that under the influence of technological stress on the body of cattle, there is a violation of the ratio of normal forms of red blood cells – discocytes and their pathological forms – stomatocytes, echinocytes, the most common are echinocytes. To correct impaired body functions, the effect of continuous and fractional exposure to low-intensity laser radiation with wavelengths of 830 nm and 650 nm was studied. The obtained data indicate that the NILI with a wavelength of 650 nm and 830 nm does not have a negative effect on the morphology of bovine red blood cells. The stimulating and normalizing effect of low-intensity laser radiation on red blood cells was most pronounced in a continuous mode of exposure with a wavelength of 830 nm.
