To study the chemical constituents of Drynariae Rhizoma, nine phenolic acids were isolated from a 70% ethanol extract by using a combination of various chromatographic techniques including column chromatography over silica gel, ODS, Sephadex LH-20, and semi-preparative HPLC. By spectroscopic techniques including 1H NMR, 13C NMR, 2D NMR, and HR-ESI-MS, these compounds were identified as 4, 4'-dihydroxy-3, 3'-imino-di-benzoic acid (1), protocatechuic acid (2), gallic acid (3), p-hydroxybenzoic acid (4), (E)-caffeic acid (5), ethyl trans-3, 4-dihydroxycinnamate (6), caffeic acid 4-O-beta-D-glucopyranoside (7), p-coumaric acid 4-O-beta-D-glucopyranoside (8), and 23(S)-12-O-caffeoyl-12-hydroxyllauric acid glycerol ester (9), separately. Among them, 1 and 9 are new compounds, and 3, 4, and 6 were isolated from Drynaria species for the first time.

BACKGROUND: The red blood cell (RBC) deformability test is a useful method for measuring the ability of RBCs to adapt their shape to the flow conditions. Using this test, several investigators have shown the relationship between RBC deformability and numerous clinical conditions. For the quality control (QC) of RBC deformability test, we evaluated whether frozen-thawed-deglycerolized RBCs can be used as QC materials. METHODS: Packed RBCs were frozen with 40% (wt/vol) glycerol and stored at -80degrees C for 3 months. For 10 different frozen RBC panels, RBCs were thawed, deglycerolized and stored at 4degrees C for 4 weeks. Using microfluidic ektacytometer, we measured RBC deformability of the thawed RBCs. The stability of thawed RBCs was tested once a day for 28 days of storage time and was analyzed by simple regression analysis. The precision of the test using thawed RBCs was analyzed for 7 days of storage time by calculation of CV values of intra-assay (10 measurements/assay) and between-day measurements. RESULTS: Frozen-thawed-deglycerolized RBCs were stable for 1 week. Within-run and between-day precisions of the RBC deformability test during 7 days of storage of thawed RBCs were 1.4-2.9%, and 1.9-2.8%, respectively. CONCLUSIONS: Frozen-thawed-deglycerolized RBCs used in RBC deformability test showed satisfactory within-run and between-run precisions and stability for one week after thawing, and may be used as QC materials for this test.

OBJECTIVETo observe the effect of the experiential compound prescription Shenshuai compound medicine (SSCM) on acute renal failure (ARF) rats, and expose its mechanism.
METHODMale SD rats were allocated into four groups at random. Except normal group, the others were injected glycerin into the musculi to induce a model of ARF. At the same time, rats in normal and model groups were given a dose (10 mL x kg(-1)) of normal saline; rats in the other two groups were given verapamil (Vp) 40 mg x kg(-1) x d(-1) and SSCM 22.5 mg x kg(-1) x d(-1) respectively by gastric gavages. In this way they were killed at 24 h after injecting glycerin.
RESULTIn contrast with model group, SSCM and Vp could ameliorate the renal function of acute tubular necrosis (ATN) rats markedly, in a way protect the renal inherent cell ultrastructure such as tubular epithelial cell etc at ATN early-stage; especially SSCM could enhance NO contents in serum, and was reduce ET levels inplasma, evidently cut down TNF-alpha contents in serum, and was partly superior to Vp.
CONCLUSIONIt is indicated that SSCM can adjust thebalance of contract and stretch blood vessal active substance and clear away initiate inflammatory medium, consequently alleviate renal pathological changes, prevent and treat ARF.
