Introduction
Taking the GSR to acupoints in rheumatoid arthritis, we observed the following 3 points: the comparison between rheumatoid arthritis and osteoarthritis, the relativity between the clinical symptoms and acupoints, and the effect of acupuncture on the pathema.
Method
Using an apparatus “Memorador Model F-532”, we measured the GSR to SP-3, LV-3, BL-64, GB-40, ST-42, ST-36 and SP-6 together with a check on this symptom and hemanalysis.
Effect
The GSR in rheumatoid arthritis was higher than the other. The GSR in active rheumatoid arthritis was lower than the inactive. It was showed that there were significant differences in KI-3 (significance level under 5%) and SP-6 (under 1%).
Conclusion
We assumed that the pathema might be dependent on the condition of their acupoints. Acupuncture gave a good effect on rheumatoid arthritis.

Objective: To compare effects of the fluoropyrimidines S-1 and capecitabine on prothrombin time international normalized ratios (PT-INR) of warfarin following coadministration and after discontinuation of each fluoropyrimidine treatment.
Methods: Medical records of patients receiving warfarin with either S-1 (6 patients) or capecitabine (7 patients) were obtained from four hospitals.
Results: Increased PT-INR was observed until peak levels of warfarin were achieved in all patients in S-1 and capecitabine treatment groups. Moreover, PT-INR significantly changed after coadministration within each group (p<0.05). Specifically, ratios of peak PT-INR after coadministration of each fluoropyrimidine and those following administration of warfarin alone (PT-INR elevation ratio) were 3.31 and 3.29 in S-1 and capecitabine coadministration groups, respectively. Moreover, numbers of days to peak PT-INR were 38.3 and 31.3 days, respectively, and did not significantly differ between the treatment groups. Furthermore, PT-INR returned to pretreatment levels by 17.5 and 15.1 days after discontinuation of S-1 and capecitabine, respectively, and did not significantly differ between the treatment groups.
Conclusion: Coadministration of S-1 and capecitabine similarly prolongs PT-INR by approximately 3-fold compared with administration of warfarin alone; therefore, these drug-drug interactions were clinically suggested to be of high risk for episodes of bleeding and remarkable alterations in coagulation parameters. Therefore, blood coagulation ability should be more carefully monitored with regard to PT-INRs in patients receiving warfarin with S-1 or capecitabine not only during coadministration but also after discontinuation of fluoropyrimidine treatments.

The development of clinically applicable scaffolds is important for the application of cell transplantation in various human diseases. The aims of this study are to evaluate fibrin glue in a novel protein replacement therapy using proliferative adipocytes and to develop a mouse model system to monitor the delivery of the transgene product into the blood and the fate of the transduced cells after transplantation. Proliferative adipocytes from mouse adipose tissue were transduced by a retroviral vector harboring the human lecithin-cholesterol acyltransferase (lcat) gene, and were subcutaneously transplanted into mice combined with fibrin glue. The lcat gene transduction efficiency and the subsequent secretion of the product in mouse adipocytes were enhanced using a protamine concentration of 500 microg/ml. Adipogenesis induction did not significantly affect the lcat gene-transduced cell survival after transplantation. Immunohistochemistry showed the ectopic enzyme production to persist for 28 days in the subcutaneously transplanted gene-transduced adipocytes. The increased viability of transplanted cells with fibrin glue was accompanied with the decrease in apoptotic cell death. The immunodetectable serum LCAT levels in mice implanted with the fibrin glue were comparable with those observed in mice implanted with Matrigel, indicating that the transplanted lcat gene-transduced adipocytes survived and functioned in the transplanted spaces with fibrin glue as well as with Matrigel for 28 days. Thus, this in vivo system using fibrin is expected to serve as a good model to further improve the transplanted cell/scaffold conditions for the stable and durable cell-based replacement of defective proteins in patients with LCAT deficiency.

Auto-transplantation of adipose tissue is commonly used for the treatment of tissue defects in plastic surgery. The survival of the transplanted adipose tissue is not always constant, and one of reasons is the accelerated apoptosis of the implanted preadipocytes. We have recently established highly homogeneous preadipocytes, named ccdPAs. The aim of the current study was to evaluate the regulation of the potency of platelet-rich plasma (PRP) on the apoptosis of ccdPAs in vitro. PRP stimulated the proliferation of the preadipocytes in a dose-dependent manner, and the stimulatory activity of 2% PRP was significantly higher than that of 2% FBS or 2% platelet-poor plasma (PPP). The presence of 2% PRP significantly inhibited serum starvation- or TNF-alpha/cycloheximide-induced apoptosis in comparison to 2% FBS or 2% PPP. DAPK1 and Bcl-2-interacting mediator of cell death (BIM) mRNAs were reduced in the preadipocytes cultured with 2% PRP in comparison to those cultured in 2% FBS. The gene expression levels were significantly higher in cells cultured without serum in comparison to cells cultured with 2% FBS, and the levels in the cells with 2% PRP were reduced to 5-10% of those in the cells without serum. These results indicated that ccdPAs exhibit anti-apoptotic activities, in addition to increased proliferation, when cultured in 2% PRP in comparison to the same concentration of FBS, and that this was accompanied with reduced levels of DAPK1 and BIM mRNA expression in in vitro culture. PRP may improve the outcome of transplantation of adipose tissue by enhancing the anti-apoptotic activities of the implanted preadipocytes.
