The screening study of the effects of several new diethylamino- and dimethylaminoethanol fumaric esters with Krebs cycle intermediates on the physical performance of male mice in the forced swimming test have been conducted. The compounds: Fumarate-DMAE-Fumarate at a dose of 75 mg/kg and Fumarate-DEAE-Succinate at a dose of 10 mg/kg, as well as Diethylaminoethanol (DEAE base) at a dose of 50 mg/kg. The study has shown that their effect on physical performance surpassed the comparison drug, deanol aceglumate, used at the optimal dose of 50 mg/kg. The latter provided a 74% increase in the maximum swimming time of animals, while the studied compounds showed +175%, +162%, +121% results compared to control. The actoprotective activity of the compounds Fumarate-DMAE-Fumarate (75 mg/kg dose) and Fumarate-DEAE-Succinate (FDES) (10 mg/kg dose) is comparable to the effect of ethylthiobenzimidazole hydrochloride (25 mg/kg dose).

The purpose of the present study was to determine the effects of polysaccharide from Rhodiolae Radix (PRR) on physical fatigue using a forced swimming test in male mice. 96 mice were divided randomly into four groups based on body weight (n = 24). One of the groups was the control group; the others were PRR supplemented groups (25, 50 and 100 mg/kg body weight). Forced swimming test of mice were carried out after 28 days of PRR administration, and the blood lactic acid (BLA), blood urea nitrogen (BUN), liver glycogen and muscle glycogen contents were determined. The data suggest that PRR can extend the exhaustive swimming time of the mice, as well as increase the tissue glycogen contents, and decrease the BLA and BUN contents. These results indicated that PRR had significant anti-fatigue effects.DOI: http://dx.doi.org/10.3329/icpj.v2i3.13579 International Current Pharmaceutical Journal, February 2013, 2(3): 49-52

In the present study, we investigated the anti-fatigue activity in male Kunming mice with Soy isoflavones using a forced swimming test. Mice were divided into four groups (three Soy isoflavones administered groups and a control group). The control group was gavaged with distilled water and Soy isoflavones administered groups were gavaged with Soy isoflavones (10, 20 and 40mg/10g body weight /d). After four weeks, a forced swimming test was performed and the biochemical parameters related to fatigue were examined. The results suggested that Soy isoflavones could extend the swimming time to exhaustion of the mice. This indicated that Soy isoflavones had anti-fatigue activity and could elevate the exercise tolerance.

In the present study, we investigated the anti-fatigue activity in male Kunming mice with pecan oil using a forced swimming test. Mice were divided into four groups (three pecan oil administered groups and a control group). The control group was gavaged with distilled water and pecan oil administered groups were gavaged with pecan oil (10, 20 and 30mg/10g body weight /d). After four weeks, a forced swimming test was performed and the biochemical parameters related to fatigue were examined. The results suggested that pecan oil could extend the swimming time to exhaustion of the mice, as well as increase the tissue glycogen contents, while decreasing the blood lactate and serum urea nitrogen contents. This indicated that pecan oil had anti-fatigue activity and could elevate the exercise tolerance.

This study investigated the effects of polysaccharides from the root ofCodonopsis pilosula(PCP) on physical fatigue induced by forced swimming in mice. The mice were divided into five groups, i.e., one control group and four PCP-treated groups. The control group was given distilled water and four PCP-treated groups were given different doses of PCP (100, 200, 400, 800 mg/kg). After 28 days, anti-fatigue effects of PCP were assessed using the forced swimming test, and the exhaustive swimming times, blood lactic acid (BLA), serum urea nitrogen (SUN), liver glycogen and muscle glycogen were measured. The data showed that PCP could prolong exhaustive swimming time of mice by decreasing BLA and SUN levels, and by improving the liver and muscle glycogen contents. The results clearly demonstrate that PCP had anti-fatigue effects.

В наших предыдущих исследованиях было показано, что ингибитор пролинспецифической пептидазы дипептидилпептидазы-IV (ДП-IV, EC 3.4.14.5) трипептид дипротин А, введенный крысам в 5-18 постнатальные дни, приводит к развитию у крыс подросткового возраста и взрослых животных эмоционально-мотивационных расстройств. Такие расстройства можно рассматривать как модель смешанного тревожно-депрессивного состояния. Однако специальных исследований по валидности данной модели проведено не было. Цель настоящей работы состояла в проверке влияния трициклического антидепрессанта имипрамина (ИМИ) на депрессивноподобное поведение крыс и уровень кортикостерона в сыворотке крови животных на модели смешанного тревожно-депрессивного состояния. Методика. У крыс в возрасте одного и двух мес. определяли уровень тревожности в автоматизированном тесте «Приподнятый крестообразный лабиринт» и оценивали депрессивноподобное поведение в тесте принудительного плавания. ИМИ вводили взрослым животным в течение 10 дней (20 мг/кг/день, интрагастрально). Уровень кортикостерона в сыворотке крови определяли методом твердофазного иммуноферментного анализа. Результаты. Неонатальное действие дипротина А приводило к повышению тревожности у крыс в возрасте 1 мес. Депрессивноподобное поведение обнаружено у животных в возрасте одного и двух мес. ИМИ нормализовал поведение животных в тесте принудительного плавания и снижал уровень кортикостерона в сыворотке крови крыс. Кроме того, ИМИ снижал вес крыс. Заключение. Результаты исследования свидетельствуют в пользу адекватности модели смешанного тревожно-депрессивного расстройства, возникающего у крыс вследствие действия ингибитора ДП-IV дипротина А на второй-третьей неделях постнатального развития, клиническому прообразу заболевания по критериям «внешней схожести», прогностической и конструкционной валидности. Previously, we have shown that the inhibitor of proline-specific peptidase, dipeptidyl peptidase-IV (DP-IV, EC 3.4.14.5), tripeptide diproptin A administered on postnatal days 5-18 induced emotional and motivational disorders in adolescent and adult rats. These disorders can be considered a model of a mixed anxiety-depression-like disorder. However, validation studies of this model are not available. The aim of this work was to test the effect of the tricyclic antidepressant, imipramine (IMI), on depressive-like behavior in rats and the level of serum corticosterone using the model of mixed anxiety-depressive state. Methods. The level of anxiety was assessed by the automated Elevated Plus Maze test and the depressive-like behavior was evaluated by the forced swimming test in one- and two-month old rats. IMI was administered to adult animals for ten days (20 mg/kg a day, intragastrically). Serum corticosterone concentrations were measured using ELISA. Results. The neonatal exposure to diprotin A increased anxiety in one-month old rats. The depressive-like behavior was observed in animals aged one and two months. IMI normalized behavior of animals in the forced swimming test and reduced serum levels of corticosterone. Also, IMI reduced body weight of rats. Conclusion. The results of the study evidenced adequacy of the model of mixed anxiety-depressive state induced by the DP-IV inhibitor, diprotin A, on the second and third postnatal weeks to the clinical prototype of disease according to criteria of face validity, predictive and construct validity.
