The root of Pseudostellaria heterophylla Pax et Hoffm. (Caryophyllaceae) is a herbal medicine called Taejasam(太子蔘) and used as a good tonic in China that strengthens the functions of the lung and the stomach like Ginseng in Korea. It has been known to have the antitussive activity for tuberculosis, appetizing effect and antifatigue activity, and so on. Especially it has been known to generate body fluids for the severe thirst and the shortage of water in body after a febrile disease for a long time. Recently some components of cyclic peptides, pseudostellarins A,B,C,D,E,F,G, that inhibit the activity of tyrosinase, were separated from this root. In this report several biological activities including acute toxicity, analgesic activity, antifatigue activity, bile juice increasing activity, hepatoprotective activity and antiinflammatory activity were investigated. These results showed as such; $LD_{50}$ of methanol extracts was above 10,000 mg/kg. The analgesic effect was revealed in the writhing test using rats. The BuOH fractions showed a prominent antifatigue effect against immobilized stress, significant hepatoprotective activities against $CCl_4$ intoxication and inhibitory effect on carrageenin-induced edema in rat's paw.

A ginseng preparation consisting of ginseng ext., lycii fructus ext., four vitamins and caffeine was chosen and its efficacy was evaluated with respect to nutritional supplement, antifatigue activity and liver protective action. Animals administered orally in both one-third and three fold doses of the preparation showed no significant increments of their body weights when compared with those of the normal animals, suggesting no supplemental activity. However, the preparation in the above two doses significantly prolonged swimming time to 53 and 63%, respectively. Ginseng and lycii fructus ext. were found to be responsible for the antifatigue activity. And also the preparation significantly inhibited lipid peroxidation of mouse liver after ethanol-induced acute intoxication.

Background: Both ginsenoside Re and B-complex vitamins are widely used as nutritional supplements. They are often taken together so as to fully utilize their antifatigue and refreshing effects, respectively. Whether actually a drug-nutrient interaction exists between ginsenoside Re and B-complex vitamins is still unknown. The objective of this study was to simultaneously investigate the effect of B-complex vitamins on the antifatigue activity and bioavailability of ginsenoside Re after their oral administration. The study results will provide valuable theoretical guidance for the combined utilization of ginseng and B-complex vitamins. Methods: Ginsenoside Re with or without B-complex vitamins was orally administered to mice to evaluate its antifatigue effects and to rats to evaluate its bioavailability. The antifatigue activity was evaluated by the weight-loaded swimming test and biochemical parameters, including hepatic glycogen, plasma urea nitrogen, and blood lactic acid. The concentration of ginsenoside Re in plasma was determined by liquid chromatography-tandem mass spectrometry. Results: No antifatigue effect of ginsenoside Re was noted when ginsenoside Re in combination with B-complex vitamins was orally administered to mice. B-complex vitamins caused to a reduction in the bioavailability of ginsenoside Re with the area under the concentration-time curve from zero to infinity markedly decreasing from $11,830.85{\pm}2,366.47h{\cdot}ng/mL$ to $890.55{\pm}372.94h{\cdot}ng/mL$. Conclusion: The results suggested that there were pharmacokinetic and pharmacodynamic drug-nutrient interactions between ginsenoside Re and B-complex vitamins. B-complex vitamins can significantly weaken the antifatigue effect and decrease the bioavailability of ginsenoside Re when simultaneously administered orally.

Extract of drugs in commerce was administered to mice for 3 days and 7 days and its antifatigue effects were compared with those of P. ginseng extract and A. sessiliflorum extract. Mice were used for these experiments divided into ethyl alcohol and water extract of R. glutinosa(saengjihwang), R. glutinosa (sookjihwang), A. japonica(changchool), A. japonica(baekchool), P. officinale, C. japonica, C. morifolium, A. calamus were given ordinary dose rally. For antifatigue test, swimming performance were determined after the extract administration. The group of P. officinale gave high improvement of the swimming performance in ethyl alcohol extract group.

Systematic pharmacological studies on powdered whole part of unossified antler obtained from Cervus nippon Temminck var. mantchuricus have been carried out in mice and rats. Powdered antler, with a single oral administration, showed a very weak acute and subacute toxicity; its MLD being >5g/kg orally in mice. On daily oral treatments of the antler for 14 days, it did not cause any significant differences in body weight gain, various organ weights and serum transaminase activities compared to those of the control rats. Powdered antler, with a single oral administration, showed a remarkable analgesic activity as evaluated by writhing syndrome and tail-pressure test, a weak CNS depressant activity as well as a weak immunopotentiating action as evaluated by carbon clearance test in mice. Powdered antler, with repeated treatments, showed a moderate antifatigue effect against immobilized stress and showed significant increases in both adrenal weight and its ascorbic acid content in rats, suggesting that the mode of antifatigue effect of antler is related to adrenal and its components.

The acute and subacute toxicities and pharmacological actions of two preparations of Ssanghwa Tang prescriptions have been evaluated in mice, rats and rabbits. The two prescriptions were found to be safe drugs because those preparations exhibited almost no acute and subacute toxicities even at a high dosage level. The two prescriptions elicited CNS depressant activities characterized by potentiation of hexobarbital-induced narcosis, antipyretic activity in typhoid-vaccinated rabbits and a significant antifatigue effect against cold immobilized stress, the activities of prescription B being more potent.

Effect of garlic intake on the antifatigue and fatigue recovery during prolonged exercise have been investigated. 16 male college students(8 persons of control group and the same numbers of garlic intake group), aged from 20 to 22 years, were subjected to the restricted experiment and maintained their same menu with exercise in life pattern during 14 days of program. In garlic intake group, 30g of garlic was given with every 3 meal per day to each person. A significant increase in HDL-cholesterol level was shown in the garlic intake group while total cholesterol, LDL-cholesterol and lactate level decreased by garlic intake. Lactate dehydrogenase activity in serum increased by garlic intake, however garlic intake was not significantly affected on Vo2, Vco2, ventilation, respiratory quotient. In conclusion, garlic intake seemed to be effective for antifatigue and tatigue recovery during prolonged exercise.

Acharan sulfate (AS) is a glycosaminoglycan (GAG) prepared from the giant African snail, Achatina fulica. In this study, some biological activities of AS were evaluated on the basis of structural similarities to heparin/heparan sulfate and the biological functions of GAGs. We demonstrated that it exhibited strong immunostimulating activities as measured by carbon clearance test in mice and in vivo phagocytosis. It also exhibited a significant hypoglycemic activity in epinephrine (EP)-induced hyperglycemia as well as antifatigue effects by weight-loaded forced swimming test. And it showed hypolipidemic activities in cholesterol-rich mixture induced hyperlipidemia in rats. The above results indicate that AS has diverse biological activities and suggest therapeutically important target molecules.

Total ethanol extract of chinese drugs was administered to mice for 4 weeks (small dosage group) and 3 days (large dosage group), and its antifatigue effects and hepatonic activities were compared with those of P. ginseng and A. sessiliflorum. 1. In the long-term administration of extracts, the swimming performance peaked at 2 weeks, and the recovery effects on the intoxicated liver appeared to be significant in the extracts of P. officinale, P. cocos and A. cochinchinensis among tested chinese drugs. 2. The large dose administration of extracts gave high improvement of recovery effect on the intoxicated liver.
