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.     

Lack of standardization in performance of the semen analysis among laboratories in the United States

OBJECTIVE: To determine the level of standardization in performance of the semen analysis among clinical laboratories in the United States.DESIGN: A survey was mailed to laboratories requesting information about the laboratory and performance of the semen analysis. Responses were received from 536 laboratories.SETTING: Clinical laboratories enrolled in the American Association of Bioanalysts Andrology Proficiency Testing Program.PATIENT(S): None.INTERVENTION(S): None.MAIN OUTCOME MEASURE(S): Agreement among laboratories.RESULT(S): Sixty-one percent of respondent laboratories were part of an assisted reproductive technology program. The laboratories perform less than 50 (53%), less than 10 (25%), or less than 5 (16%) andrology laboratory procedures per month. The laboratories routinely report sperm count (94% of laboratories), motility (95%), morphology (85%) and forward progression (69%), and semen volume (96%) as part of the semen analysis. Only 64% of laboratories routinely report abstinence, and 60% of laboratories indicate the criteria used for sperm morphology on the report form. The most common lower limits of normality for sperm count and motility were >20 x 10(6)/mL (77% of laboratories) and >50% (59% of laboratories), respectively. Few laboratories performed quality control for sperm counts (29%), motility (41%), and morphology (41%).CONCLUSION(S): These data indicate a significant lack of standardization in the performance and reporting of semen analyses among laboratories in the United States.
