It has been found that various stress challenges induce the myocardial antioxidant enzymes and produce an acquisition of the cellular resistance to the ischemic injury in animal hearts. Most of the stresses, however, seem to be guite dangerous to an animal's life. In the present study, therefore, we tried to search for safely applicable stress modalities which could lead to the induction of antioxidant enzymes and the production of myocardial tolerance to the ischemia-reperfusion injury. Male Sprague-Dawley rats (200-250 g) were exposed to various non-fatal stress conditions, i.e., hyperthermia (environmental temperature of $42^{\circ}C$ for 30 min, non-anesthetized animal), iramobilization (60 min), treadmill exercise (20 m/min, 30min), swimming (30 min), and hyperbaric oxyflenation (3 atm, 60 min), once a day for 5 days. The activities of myocardial antioxidant enzymes and the ischemia-reperfusion injury of isolated hearts were evaluated at 24 hr after the last application of the stresses. The activities of antioxidant enzymes, superoxide dismutase (SOD), catalase, glutathione peroxidase, glutathione reductase and glucose-6-phosphate dehydrogenase (G6PD), were assayed in the freshly excised ventricular tissues. The ischemia-reperfusion injury was produced by 20 min-global ischemia followed by 30 min-reperfusion using a Langendorff perfusion system. In swimming and hyperbaric oxygenation groups, the activities of SOD and G6PD increased significantly and in the hyperthermia group, the catalase activity was elevated by 63% compared to the control. The percentile recoveries of cardiac function at 30 min of the post-ischemic reperfusion were 55.4%, 73.4%, and 74.2% in swimming, the hyperbaric oxygenation and the hyperthermia groups, respectively. The values were significantly higher than that of the control (38.6%). In additions, left ventricular end-diastolic pressure and lactate dehydrogenase release were significantly reduced in the stress groups. The results suggest that the antioxidant enzymes in the heart could be induced by the apparently safe in vivo-stresses and this may be involved in the myocardial protection from the ischemia-reperfusion injury.

The aim of the present study was to evaluate the possibility of protective effectness of swimming exercise and Gastrodia elata blume oral administration against beta-cell damage in streptozotocin (STZ)-induced diabetes in rats. The animals were divided into five groups: the normal group(n=10), the STZ-induced diabetes group(n=10), the STZ-induced diabetes and moderate-intensity exercise group(n=10), the STZ-induced diabetes Gastrodia elata blume(300 mg/kg) oral administration group(n=10), the STZ-induced diabetes and moderate-intensity exercise and Gastrodia elata blume(300 mg/kg) oral administration group(n=10). Animals in the exercise groups were made to swim moderate swimming exercise protocols once a day for 4 consecutive weeks. Serum glucose concentration and insulin level, superoxide dismutase (SOD) and catalase (CAT) were measured in serum. Swimming exercise and Gastrodia elata blume extract administration has shown anti-diabetic effect probably through decreasing serum glucose and insulin level and increasing antioxidant enzyme activity.

Red ginseng (RG, the extract of Panax ginseng Meyer) has various biological and psychological activities and may also alleviate fatigue-related disorders. The present study was undertaken to evaluate what kind of fatigue red ginseng alleviate. Animals were orally administered with 50, 100, 200, 400 mg/kg of RG for 7 days. Before experiments were performed. Physiological stress (swimming, rotarod, and wire test) are behavioral parameters used to represent physical fatigue. Restraint stress and electric field test to a certain degree, induce psychological fatigue in animals. Plasma concentration of lactate and corticosterone (CORT) were also measured after these behavioral assays. RG supplementation (100 mg/kg) increased movement duration and rearing frequency of restrainted mice in comparison with control. 100 and 200 mg/kg of RG increased swimming time in cold water ($8{\pm}4^{\circ}C$) while at 100 mg/kg, RG increased electric field crossing over frequencies. 50, 100 and 200 mg/kg RG prolonged running time on the rotarod and at 100 mg/kg, it increased balancing time on the wire. RG at those doses also reduced falling frequencies. RG supplementation decreased plasma CORT levels, which was increased by stress. Lactate levels were not significantly altered. These results suggest that RG supplementation can alleviate more the damages induced by psychological than physical fatigue.

The purpose of this study was to examine the anti-depressive effects of OnDam-Tang with addition of Linderae Radix (ODT-L) on the animal model of depression induced by chronic immobilization stress. Depression model was made by chronic immobilization stress for 2 hours for 21 days. And we performed forced swimming test, analysis of the neurotransmitter and immunohistochemical staining, measured expression levels of serotonin in the brain. ODT-L has decreased immobilization time in forced swimming test. ODT-L has increased amount of melatonin in the brain. ODT-L has increased expression levels of serotonin in the brain. ODT-L prevented damage in the hippocampal region. ODT-L has reduced the expression level of CRF receptors in in hippocampus region. These results suggest that ODT-L may have anti-depressive effects on depression.

This study aimed to investigate the anti-stress function of Aucklandiae Radix (AR) and Cyperi Rhizoma (CR). The essential oils used in the experiment were extracted from AR and CR using Steam Distillation Extraction and Super critical CO₂ extraction. To observe the effects of sample administration, we measured feed intake, leukocytes, red blood cells, hemoglobin, platelets, serum serotonin content, immobility time, climbing time, and swimming time in mice subjected to chronic restraint stress as behavioral changes. The average body weight of all experimental groups increased than the average body weight of the control group. The immobility and climbing times of experimental groups A and B administered with supercritical extraction samples were shorter than those of the other experimental groups and the control group, and the swimming time was longer. The serotonin content in the blood of all experimental groups decreased compared to the normal group, and the serotonin content of the control group was increased. The authors suggest that Korean herbal medicines AR and CR may be utilized as anti-stress flavoring agents based on the above results.
