Effects of Wen-Pi-Tang and its crude drug extracts on proliferation of cultured mouse mesangial cells

The efficacy of Wen-Pi-Tang and each of its crude drug extracts on the proliferation of mouse mesangial cells was determined in terms of [³H]thymidine uptake. When Wen-Pi-Tang was added to the medium of mesangial cell cultures, it suppressed the proliferation of mesangial cells markedly. Similar to the effects of Wen-Pi-Tang, Rhei Rhizoma, its main ingredient, exerted an inhibitory effect on mesangial cell proliferation at a relatively low concentration. Ginseng Radix and Aconiti Tuber were also an effective crude drug. As for Zingiberis Rhizoma, an inhibitory activity at relatively high concentration was noted. However, the proliferation of mesangial cells in the presence of Glycyrrhizae Radix showed no particular alteration. As is clear from the results of the present study, Rhei Rhizoma, Ginseng Radix, Aconiti Tuber and Zingiberis Rhizoma alone each exert an inhibitory effect. The inhibition of mesangial cell proliferation by Wen-Pi-Tang can thus be explained by the action of these crude drugs.     

The results of short-term (6 months) high-dose testosterone treatment on bone age and adult height in boys of excessively tall stature

Forty-nine pubertal tall boys with a mean height prediction of 203.59 cm according to the Bayley-Pinneau (BP) method were treated prospectively with 500 mg testosterone-oenanthate every 2 weeks for a period of 6 months. Before therapy chronological age (CA) was 14.14 years and bone age (BA) 13.88 years using the Greulich-Pyle (GP) method. During therapy BA advanced by 1.37 years. It continued to accelerate during the 6 months following therapy with the mean BA/CA being 3.01 at 3 months and 2.24 at 6 months after therapy. The 6 months value was only slightly less than the BA/CA of 2.47 obtained during therapy. The reduction in adult height was 7.26 cm or 50.8% of the predicted further growth in 12 boys with a long-term follow up of 2.5 years. This is similar to the 51.6% or 9.63 cm observed in 50 boys with a long-term follow up after 14.25 month treatment until a BA of 17 years or more. It is concluded that in the majority of cases high-dose testosterone therapy in boys of tall stature can be limited to a 6-month treatment period. Reassessment of the height prediction after a 6-month interval without therapy should define those patients who have to resume treatment because of their remaining excessive growth potential.Abbreviations CA chronological age - BA bone age - GP Greulich-Pyle - BP Bayley-Pinneau - T testosterone oenanthate - TW Tanner-Whitehouse     

医学影像专业教学如何适应现代高素质人才需求的挑战

随着计算机及数字化技术的快速发展，医学影像检查设备不断创新，医学影像学已经成为当代医学新兴重要学科。近几年我国经济和科技有了长足的进步，许多大型医学影像设备如彩超、螺旋CT、MRI等已配备到县一级医院，沿海发达地区甚至区、镇医院亦拥有。由于我国同世界科技发达国家的差距，大部分医学影像设备有赖于进口，如何更好地发挥这些设备的社会和经济效益，培养出大批现代医学影像高素质人才，给医学影像教育提出了新任务。

Effects of a Korean herbal formulation, Silsosangami, consisting of seven medicinal herbs, and its seven herbs on endotoxin-induced experimental thrombosis in rats

A traditional Korean medicine, Silsosangami (SSG), consisting of seven different herbs of Typhae Pollen, Pteropi Faeces, Paeoniae Radicis rubra, Cnidii Rhizoma, Persicae Semen, Carthami Flos and Curcumae Tuber, has been reported to have a hypolipidemic effect in human subjects. In the present study, the inhibitory effects of SSG on a thrombosis in rats, induced by endotoxin treatment were examined. The anti-thrombic properties of SSG were also investigated with respect to blood parameters. The extracts of SSG and five of the seven herbs, except Cnidii Rhizoma and Carthami Flos, inhibited both endotoxin-induced disseminated intravascular coagulation (DIC) and thrombosis in rats. The extract also inhibited the endotoxin-induced decrease in blood platelets and fibrinogen, and the endotoxin-induced increase in fibrin degradation products (FDP) on disseminated intravascular coagulation in normal rats. In conclusion, the artificially induced, protective effects of SSG on ischemic infarction might be related to their inhibitory effects on DIC, platelet coagulation and thrombotic action.     

Ether fraction of methanol extracts of Gastrodia elata,medicinal herb protects against neuronal cell damage after transient global ischemia in gerbils

Gastrodia elata (GE), a medicinal herb, has been used traditionally for the treatment of convulsive diseases such as epilepsy in oriental countries including South Korea and still occupies an important place in traditional medicine in Asia. We designed this study to examine whether the ether fraction of methanol extracts (EFME) of GE protects the hippocampal neuronal damage induced by transient global ischemia in a gerbil model. Gerbils were treated with the EFME of GE (200 or 500 mg/kg per day, p.o.) for 14 days before brain ischemia. The lower dose of EFME of GE failed to attenuate the hippocampal neuronal damage in the CA1 region. However, the higher dose of EFME of GE attenuated the hippocampal neuronal damage in the CA1 region. The present results show that the EFME of GE has a protective effect against neuronal damage following global ischemia in gerbils.
