Objective To investigate the effects of different dosages of bone marrow mesenchymal stromal cells (BMSC) on lung fibrosis. Methods BMSCs with red fluorescence protein (RFP) from male FVB mice were cultured in vitro. Twenty-four female wild type FVB mice were randomly divided into four groups: normal group, model group, BMSC 1 group and BMSC 2 group (n = 6). Mouse pulmonary fibrosis models were induced by bleomycin via single intratracheal perfusion. Twenty-four h after model establishment, mice in BMSC 1 group and BMSC 2 group were injected with 1 × 10~6 BMSCs and 2 × 10~6 BMSCs, respectively through vena caudalis for each mouse. All the animals were sacrificed 21 d after model estalishment, and mouse lung tissue samples were obtained. The pathological changes were observed by light microscopy, the hydroxyproline ( Hyp) contents were measured by alkaline hydrolysis assay, the distribution of RFP( + ) BMSCs and quantitation of RFP were analysed by laser scanning confocal microscopy and immunohistochemistry, the expression of surfactant protein A (SP-A) was detected by immunohistochemistry, and the expression of transforming growth factor-β (TGF-β) and platelet-derived growth factor (PDGF) mRNA was detected by Real-time PCR. Results Compared with model group, the pulmonary fibrosis in BMSC 1 group was significantly alleviated, and that of BMSC 2 group became much more severe.A large number of RFP( +) BMSCs were found in fibrosis area of BMSC 2 group,which exhibited morphology similar to fibroblasts. As far as the expression of SP-A was concerned, normal group was higher than BMSC 1 group, BMSC 1 group was higher than BMSC 2 group and model group (P < 0. 05), while there was no significant difference between BMSC 2 group and model group (P >0. 05). Normal group, BMSC I group, model group and BMSC 2 group fell in the increase order by Hyp contents (P <0.01, P <0.05), and BMSC 2 group, BMSC 1 group, model group and normal group fell in the decrease order by expression of TCF-|$ and PDGF mRNA (P < 0.05). Conclusion Proper dose of BMSC has a favourable effect on bleomycin-induced lung fibrosis, while excessive dose of BMSC can aggravate the fibrosis.

This study is to investigate the authenticity between COLD and HOT natural attribute in the famous Chinese medicine formulas--Zuojinwan (Coptis-Evodia 6 : 1) and Fanzuojinwan (Coptis-Evodia 1 : 6) based on mice temperature tropism, and establish an objective method to estimate the difference of two natural attribute by using a cold/hot plate differentiating technology. The results indicated that the COLD nature Zuojinwan could decrease significantly the remaining rate of HOT-symptom rat on warm pad (P < 0.05). That was not notable to COLD-symptom rat. The interference result of COLD-HOT temperature tropism to COLD/HOT symptom rat in Fanzuojinwan was the reverse with the COLD nature Zuojinwan. Meanwhile, biochemical indicators which are relative to energy metabolism such as ATPase enzyme activity and total anti-oxidant capability (T-AOC), had corresponding change in the organism. In the study, the COLD and HOT natural tendency in Zuojinwan and Fanzuojinwan which were composed by the same herbs with different proportion could be expressed qualitatively, quantitatively, objectively and directly with applying animal temperature tropism, and be verified to philosophical idea of treating disease theory with "expelling heat with cold herbs and cryopathy requiring warm prescription", not "expelling heat with heat herbs and cryopathy requiring cold prescription" in ancient traditional Chinese medicine, which brings a new approach in investigation of the nature theory of traditional Chinese medicine.

OBJECTIVETo determine the difference on purgative biopotency of different processed products of rhubarb and compare rhubarb before and after preparation.

METHODThe prime biopotency of rhubarb reference substance was determined by comparing with the control substance of sennoside B using rat purgative model. Comparing with calibrated rhubarb reference substance, the bioactivity different processed products of rhubarb was determined by the 2,2',2" method.

RESULTThe purgative biopotency of crude rhubarb was 825.22 U x g(-1). The purgative biopotency of alcohol-processed rhubarb was 699.05 U x g(-1), The purgative biopotency of steamed rhubarb were 459.76 U x g(-1). Carbonized rhubarb cannot be determinate.

CONCLUSIONCrude rhubarb showed a significantly declineing purgative biopotency after being processed, alcohol-processed rhubarb showed less than crude rhubarb and followed by steamed rhubarb. Carbonized rhubarb lost almost all purgative bioactivity.
