ABSTRACT
The petroleum ether fraction of ethanol extract of Acorus tatarinowii were separated by column chromatography and recrystallization to afford seven compounds. On the spectroscopic analysis, they were identified as 1-hydroxy-7(11),9-guaiadien-8-one (1), calamenone(2), cis-asarone(3), chrysophanol (4), physcion (5), emodin (6), (+)-galbacin (7). Compound 1 is a new compound. Compounds 4-7 were isolated from this plant for the first time.

Objective Effect of spirulina's complex preparation(SACP) on morphologies and protein expression of HSP70 in myocardium, skeletal muscle and liver tissue were investigated in the mice during 4-week prolonged exhaustive exercise . Methods Male mice were divided into 5 groups as follow: N(control), M(exercise with moderate intensity), MS(exercise with moderate intensity plus spirulina supplementation), F(exercise with increasing intensity) and FS(exercise with increasing intensity plus spirulina supplementation). Light microscope and electron microscope were used to observe the effect of SACP on morphologies in myocardium, skeletal muscle and liver tissue in mice in group F and group FS. HSP70 protein expression was detected by immunohistochemical method. Results Under the light microscope, edema, degeneration and necroses in myocardium, skeletal muscle and liver tissues were found in the mice of group F, and fragmentation of muscle fiber, cell swelling, mitochondrial swelling and nucleoplasm solution in myocardium, skeletal muscle were found under the electron microscope in the mice of group F. The aforementioned lesions of myocardium, skeletal muscle and liver tissue in the mice of group FS were obviously alleiated. HSP70 protein expression in myocardium, skeletal muscle cells and liver cells in swimming mice was significantly higher than that in control (P0.05). Conclusions SACP had protecting effect against the microtrauma in myocardium, skeletal muscle and liver tissues caused by prolonged exhaustive exercise, and the effect was probably related to the improvement of the protein expression of HSP70 affected by SACP supplementation.
ABSTRACT
Object To study the antitumor action of KANGXIANLING (KXL), a traditional herbal preparation and its mechanism of action at molecular pharmacological level. Methods Effect of KXL containing serum on cell periferation and protein expression of P 21 WAF1/CIP1 of human hepatic cancer HepG 2 were studied by serologic pharmacologic tests. Results KXL containing serum at concentrations of 18, 9, 3 g/kg inhibited proliferation of ex vivo cultured HepG 2 cells by (63.09?5.08)%,(55.09?4.09)%, and (48.08?4.08)% respectively. Their cytotoxicities were (48.06?4.08)%, (38.09?5.01)%, and ( 25.00? 4.13)% respectively, which were all higher than that of blank serum without KXL (P
ABSTRACT
The experiments were carried out in mice to investigate the effects of acupuncturing Tsusanli (AT) on physical work capacity and neuroendocrino-immunological system. Mice were divided into four groups. The general health condition of the animals during the experimental period, the swimming duration, the content of hemoglobin and T, C, T/C, C 3, C 4 of alexin in the serum, the coefficients of spleen and thymus were observed. Results showed that AT could effectively improve the general health condition of the mice and strengthen the mice endurance as manifested by the prolonged swimming time,the increased content of hemoglobin and T, T/C, C 3, C 4 of alexin in the serum, and the higher coefficient of spleen and thymus gland. These indicated that AT was effective in elimination of fatigue and improving the endurance performance,showing the possibility of its appllication in the field of sports medicine.
