To explore the mechanism of the absorption enhancement of Angelica dahurica extract (Ade), the absorption mechanism of baicalin in the Scutcllaria water extraction as well as the effect of Angelica dahurica extract on absorption of baicalin were investigated. In order to determine the main absorption site, everted intestinal sac model was used to study the effect of Angelica dahurica extract on the absorption of baicalin at duodenum, jejunum, ileum and colon. In situ single pass intestinal perfusion model was performed to study the absorption of various concentrations of baicalin and the effect of Angelica dahurica extract on the absorption of baicalin at the main absorption site. To authenticate the consequence of perfusion by getting the blood from the hepatic portal vein and determine the concentration of the baicalin in the blood. The result showed that baicalin could be absorbed at all of the four intestinal segments with increasing absorption amount per unit as follows: ileum > colon > jejunum > duodenum. The absorption ofbaicalin in the duodenum significantly increased with Angelica dahurica extract, thus, duodenum was chosen to be the studying site. Apparent permeability values (Papp) and absorption rate constant (Ka) of baicalin in the duodenum increased gradually with higher concentrations. When the concentration of baicalin rises to a certain degree, the absorption increase had a saturable process, the absorption of baicalin may be an active transportation. Baicalin may be not a substrate of P-gp as verapamil which had not significantly affected the Papp and Ka of baicalin. The absorption of baicalin in the duodenum significantly increased (P < 0.01) in the two models with Angelica dahurica extract and the concentration of baicalin in the blood from the hepatic portal vein showed that the Angelica dahurica extract can increase the absorption of baicalin.

Saponin frsom Cortex Albiziae (SCA) are extensively used in the clinical treatment of tumor and depression. However, SCA may cause several adverse effects, including reproductive toxicity. The present study was designed to assess the mechanism by which SCA cause reproductive toxicity in female mice. The general reproductive toxicity testing was accomplished in female Kunming mice. The animals were divided into four groups: three groups that were treated by oral gavage with 135, 270, and 540 mg·kg(-1)·d(-1) of SCA prepared in physiological saline, respectively, and one vehicle control group that was treated with physiological saline only. The gestational toxicity tests were conducted at 540 mg·kg(-1)·d(-1). The general reproductive toxicity results showed that the pregnancy rate of the SCA-treated group decreased with the pregnancy rate being decreased by 70% at 540 mg·kg(-1)·d(-1). SCA elicited maternal toxicity in the ovary and the uterus, but no fetal toxicity or teratogenicity was observed. The rates of implantation in the early, middle, and late pregnancy were all decreased, with stillbirths and maternal deaths being observed. Histopathological changes showed that SCA adversely affected the ovary and the uterus. In conclusion, SCA-induced reproductive toxicity in female mice is most likely caused by its damage to the ovary and the uterus.

OBJECTIVEMahuang-Shigao herb-pair is a famous formula composed of Ephedra and Gypsum. The herb-pair is frequently used for treating cold symptoms and bronchial asthma in the clinical practice of Chinese medicine (CM). In the present study, we evaluated evidence for the benefit of combined use of Ephedra and Gypsum by analyzing the antipyretic and anti-asthmatic activities of Ephedra-Gypsum.
METHODSThe antipyretic effects of Ephedra-Gypsum were evaluated in yeast-induced hyperthermia test. Thirty male Wistar rats were randomly divided into 5 groups, including control group, standard aspirin group, and 3 Ephedra- Gypsum groups of different doses (6, 12, 24 g/kg). Ephedra-Gypsum extract and asprin were administered orally 6 h after the injection of yeast solution and body temperature was measured every 1 h for 8 h. The antiasthmatic effects of Ephedra-Gypsum were evaluated using an ovalbumin (OVA)-induced asthmatic rat model. Thirty-six male SD rats were randomly divided into 6 groups. Rats were alternately sensitized and OVA+Al(OH) challenged by exposure to mists of ovalbumin. Ephedra-Gypsum extracts (6, 12, 24 g/kg) or dexamethasone were administered 45 min prior to the allergen challenge for 8 days. Latent period and the weight of wet to dry ratio of lung were determined. In addition, the eosinophils in blood and white blood cell (WBC) were counted by an YZ-Hemavet Analyzer.
RESULTSThe Ephedra-Gypsum extracts at test dose (6, 12, 24 g/kg) significantly and dose-dependently attenuated yeast-induced fever in rats. The Ephedra-Gypsum extracts also prolonged the latent period, reduced OVA-induced increases in eosinophils and WBC, and decreased the wet and dry weight ratio of the lungs in the anti-asthmatic test.
CONCLUSIONSThese findings indicate that the Ephedra-Gypsum extract has antipyretic and anti-asthmatic properties. Hence, the results support additional scientific evidence in prescriptions.
