To study the in situ intestinal absorption of five oligosaccharides contained in Morinda officinalis How. (sucrose, kestose, nystose, 1F-Fructofuranosyinystose and Bajijiasu). The absorption of the five oligosaccharides in small intestine (duodenum, jejunum and ileum) and colon of rats and their contents were investigated by using in situ single-pass perfusion model and HPLC-ELSD. The effects of drug concentration, pH in perfusate and P-glycoprotein inhibitor on the intestinal absorption were investigated to define the intestinal absorption mechanism of the five oligosaccharides in rats. According to the results, all of the five oligosaccharides were absorbed in the whole intestine, and their absorption rates were affected by the pH of the perfusion solution, drug concentration and intestinal segments. Verapamil Hydrochloride could significantly increase the absorptive amount of sucrose and Bajijiasu, suggesting sucrose and Bajijiasu are P-gp's substrate. The five oligosaccharides are absorbed mainly through passive diffusion in the intestinal segments, without saturated absorption. They are absorbed well in all intestines and mainly in duodenum and jejunum.

OBJECTIVETo investigate the metabolic profile of hydrocortisone-induced 'Kidney-yang deficiency syndrome'in rats and the intervention effects of Morinda officinalis.

METHODProton nuclear magnetic resonance (1H-NMR) technique was used to analyze the rat metabonome in serum. Orthogonal partial least squares discriminant analysis (OPLS-DA) were processed to analyze the metabonome difference between the control and hydrocortisone treated samples. Twelve potential biomarkers were selected, via the parameter of variable importance in the projection (VIP). Principal components analysis (PCA) was employed to process the data from the M. officinalis. treatment group and the intervention effects of M. officinalis, was investigated through the selected potential biomarkers.

RESULTAfter hydrocortisone treatment, the energy metabolism, amino acids metabolism and gut microflora environment were seriously disturbed and transmethylation was surpressed. M. officinalis could effectively alleviate the disturbance of energy and amino acids metabolism and enhance transmethylation, but could not modulate the gut microflora environment.

CONCLUSIONThe results obtained suggested that metabonomic studies could better reflect the whole status of metabolism in bio-systems, and could be treated as a potential powerful approach in pharmacological studies and investigation of the essence of 'syndrome' in traditional Chinese medicine.

OBJECTIVETo explore the protection on apoptosis and the mechanism of promoting the cytoactive of osteoblast by Morinda Root Polysaccharide through the observations of the cultured osteoblast in vitro.

METHODSPrepared blood serum with Morinda Root Polysaccharide and Morinda Root aqueous extract and cultured Osteoblast in vitro with it. The second generation osteoblasts in vitro were separated from the cranium of 24-hours newborn SD rat, which were divided into control group (adding only rat serum during cultivation), induction apoptosis group (adding trans-retinoic acid in control group), Morinda Root aqueous extract group (adding serum prepared by Morinda Root aqueous extract in induction apoptosis group) and Morinda Root Polysaccharide group (adding serum prepared by Morinda Root Polysaccharide in induction apoptosis group). Adopting fluorescence microscope, apoptosis detected by flow cytometry and gene expression of Bcl-2 and Bax detected by RT-PCR, to evaluate the effect of Morinda Root Polysaccharide on the course of osteoblast apoptosis.

RESULTSThe apoptotic rate of Morinda Root aqueous extract group and Morinda Root Polysaccharide group were significantly lower than that of induction apoptosis group (P < 0.01). The apoptosis ratio of Morinda Root Polysaccharide group was lower than that of Morinda Root aqueous extract group (P < 0.05). Expression level of Bcl-2 mRNA of apoptosis cell: control group > Morinda Root Polysaccharide group > Morinda Root aqueous extract group > induction apoptosis group (P < 0.01). Expression level of Bax mRNA: induction apoptosis group > Morinda Root aqueous extract group > control group > Morinda Root Polysaccharide group (P < 0.01). Bcl-2/Bax: control group > Morinda Root Polysaccharide group > Morinda Root aqueous extract group > induction apoptosis group (P < 0.01).

CONCLUSIONMorinda Root can inhibit the apoptosis of osteoblast induced by trans-retinoic acid in some extent. The above role of Morinda Root Polysaccharide is significant better than that of Morinda Root aqueous extract. It is indicated that Morinda Root Polysaccharide is one of the essential component of inhibiting osteoblast apotosis.

OBJECTIVETo study the angiogenesis promoting effect of Morinda officinalis oligosaccharides(MOO) on chick embryo chorioallantoic membrane (CAM).

METHODRats blood serum containing low, medium and high doses of MOO was prepared using Chinese herbs serum pharmacology method. 60 chick embryoes were randomly divided into low, medium and high doses of MOO groups, as well as NS group, blank serum group and bFGF group. Each group included 10 embryoes. CAM model was prepared after 7 days incubation. Then NS, blank serum, bFGF (2500 U x mL(-1)), three doses of serum containing MOO were added respectively onto the carriers on the CAM. CAM sample was prepared after 3 days incubation. The state of angiogenesis was observed and the number of new blood vessels was counted.

RESULTCompared with blank serum and NS group, a more specific CAM angiogenesis appearance could be observed in each MOO group and bFGF group. Compared with blank serum group, the number of new blood vessels in each MOO group increased significantly (P < 0.05). But the drug had a lower efficacy than bFGF (P < 0.05). Compared with low dose group, the number of new blood vessels increased significantly in medium and high doses groups (P < 0.05). But there was no significant difference between the latter two groups. The number of new blood vessels showed no significant difference between NS group and blank serum group.

CONCLUSIONMOO can obviously promote angiogenesis of CAM.
