To study the influence of stir-baked with sand on active ingredients, diarrhea and hepatoprotection of Herpetospermum caudigerum, the contents of herperione and herpetin in H. caudigerum before and after stir-baking with sand were analyzed by HPLC. The effect of stir-baked with sand on diarrhea of H. caudigerum TL was evaluated using the mean stool rate (MSR) and mean diarrheal index ( MDI) and the influence of stir-baked with sand on hepatoprotective effect of H. caudigerum TL was examined using a mouse model of CCl4-induced liver injury based on the analysis of serum ALT and AST activities. The results of HPLC analysis showed the content of herperione in H. caudigerum after stir-baking with sand decreased by 40.9% (P < 0.01) and the content of herpetin had no change. Pharmacodynamic results showed that the MSR and MDI of high-dose and middle-dose group of H. caudigerum TL after stir-baking with sand were significantly lower than that of high-dose and middle-dose group of H. caudigerum TL without stir-baking with sand; The high-dose and middle-dose of H. caudigerum TL with/without stir-baking with sand significantly alleviated liver injury as indicated by the decreased levels of serum ALT and AST, but the ALT and AST levels of high-dose and middle-dose group of H. caudigerum TL after stir-baking with sand were higher than that of H. caudigerum TL without stir-baking with sand. The results revealed that the stir-baking with sand could effectively relieve diarrhea effect of H. caudigerum TL, while it also reduces the hepatoprotection of H. caudigerum TL.

To explore the feasibility of chemical and biological method in evaluation of the in vitro dissolution rate of Liuwei Wuling tablet (LWT), this experiment investigated the inhibitory effect of LWT dissolving solutions on LX-2 hepatic stellate cells in 0.1% SDS dissolution medium in different dissolving periods. From these results, the cumulative dissolution rate of LWT was obtained based on the cell inhibitory rate. The dissolution rates of deoxyschizandrin, phillyrin, and Specnuezhenide were determined by HPLC method. A novel approach of self-defined weighting coefficient had been created to establish the integrated dissolution rate model. Then f2 similar factor method was used to evaluate the relevance of these two methods. The results showed that f2 values for deoxyschizandrin, phillyrin, Specnuezhenide, and the integrated dissolution were 61, 43, 61 and 75 respectively, indicating that the dissolution of multi-component integration could fully reflect the biological potency of the whole recipe. The dissolution evaluation method for multicomponent integration based on biological activity is expected to be one of the effective means for in vitro dissolution test of LWT.

To investigate the absorption kinetics of Cu B-SDC/PLC-MMs in rat different intestinal segments and compared with the absorption of Cu B suspension. The in vitro everted gut sacs model was established to study the absorption characteristics of Cu B-SDC/ PLC-MMs in rat duodenum, jejunum, ileum and colon, and the content of cucurbitacin B was detected by HPLC method, and the effects of concentrations on intestinal absorption were evaluated as well. The results showed that the absorption of Cu B-SDC/PLC-MMs was linearity at different intestine segment and different concentrations (R2 > 0.9), which was consistent with zero order rate process. The Ka of different intestine segments showed a concentration-dependent increasing along with the raised concentration of Cu B-SDC/ PLC-MMs, indicating that it was likely to be a mechanism of passive absorption. The best absorption site of Cu B-SDC/PLC-MMs was ileum, and its absorptions in different intestinal segments were superior to cucurbitacin B suspension. SDC/PLC-MMs could significantly enhance the intestinal absorption of cucurbitacin B, and the study of intestinal absorption kinetics of Cu B-SDC/PLC-MMs had gave a support to its further reasonable solidfication.

OBJECTIVEThe purpose was to compare two different ways of culturing hair follicle bulge stem cell: The defined keratinocyte-serum free medium (DK-SFM) method and the 3T3 feeder cell method.

METHODSThe morphological features of cultured bulge stem cells were investigated by inverted phase control microscopy. Immunostaining of stem cell marker cluster of differentiation 34 (CD34) and epithelial cell marker cytokeratin 19 (CK19) were performed to identify the bulge stem cell. The stemness of bulge stem cells was evaluated by colony forming efficiency (CFE) and proportion of CD34 positive cells by flow cytometry.

RESULTSHair follicle bulge stem cells could be successfully cultivated in vitro using two methods. They were both positive for CK19 and CD34. The colony forming efficiency of hair follicle stem cell cultured in DK-SFM and the 3T3 feeder cell was 69.4% and 62.2%, respectively. There was no significant difference in colony forming efficiency between these two methods (P > 0.05), while the CD34 positive cells proportion was higher in DK-SFM as 72.3% than the other as 34.7% (P < 0.05).

CONCLUSIONTwo methods are applicable to culture bulge stem cells in vitro. The 3T3 feeder cell method is complicated and can propagate a lot bulge stem cells from hair follicle, while the DK-SFM method is easier to get pure bulge stem cell.

OBJECTIVETo investigate the effect of Qianlie Huichun capsule on the microstructure and ultranstructure of prostate glandular tissue in the model rat.

METHODHynertophy of prostate model rat was established by injecting testosterone to gelding male rats. After having been fed with Qianlie Huichun capsule for 30 days, the rats were killed and prostate tissues were resected for pathomorphological studies with microscope and electromicroscope, and the diameter of glandular lumer and the height of glandular epithelial cells were measured under the microspcope for different groups of rats.

RESULTIn the model groups, the glandular epithelial cells mutiplycated notably, showing stratified and pseudostratified cells that made the glandular lumer cramped. Under the electromicroscope, the glandular epithelial cells became high columnor and the rough endoreticulum extremely expanded. But in treatment groups, the change of the diameter of the glandular lumer and the height of the glandular epithelial cells were less remarkable than those in model groups. So the differerence between the model group and the treatment groups was remarkable (P < 0.01).

CONCLUSIONQianlie Huichun capsule can depress the glandular epithelialceu multiplication of prostate gland in model rats.
