AIM: To optimize the milling and extraction rate for Naolisu Granules (Rhizoma Acori Tatarinowii, Radix Notoginseny, Pheretima Radix et Rhizoma Rhei, Radix Curcuma, Radix Ginserg Rubra, etc.). METHODS: The granularity of powder was determined by different micropowder processes. The process was studied by orthogonal design with the content of volatile oil, the yield of extract and the content of emodin. RESULTS: The optimum process of milling was that coarse powder was micropulverized for 20 min at -8℃ ～ -12℃ . The optimum extraction of volatile oil was distillated for 4 hs after volatile medical materials were macerated for 1h with 7 times amount of water. The optimum process of percolation was percolated by 300mL of 75% alcohol with 3.0mL?kg -1 ?min -1 after the medical material powders were macerated for 6 hs. CONCLUSION: These optimum processes are suitable for preparation of Naolisu Granules.

AIM:To observe the effects of hawthorn leaf polymeric procyanidins ( PPC) on calcium mobiliza-tion of vascular endothelial cells , and to study the underlying mechanism .METHODS: Free calcium in cultured human umbilical vein endothelial cells (HUVECs) was labeled with Fura-2.HUVECs were treated with ATP, a positive control drug, and PPC at concentrations of 12.5, 25 and 50 mg/L..The intracellular calcium concentrations were measured with a living cell microscope for 30 min.RESULTS:PPC concentration-dependently increased the intracellular calcium concen-tration of HUVECs .The intracellular calcium concentrations in 25 and 50 mg/L PPC groups were significantly higher than that in normal group (P<0.01).The dynamic manner of calcium concentration elevations elicited by PPC was a slow in -crease which happened after a latency time of several minutes , lasted for several minutes , and reached a plateau finally . This manner was quite different from that elicited by ATP , a typical SOC operator , hinting different mechanisms between them .Inhibiting the intracellular calcium release did not influence the effects of PPC;however , deleting extracellular calci-um, inhibiting the reverse mode of Na +-Ca2+exchange, or deleting extracellular sodium , restrained or even abolished the effects of PPC.CONCLUSION:PPC elicits calcium mobilization in vascular endothelial cells , which may be one of the mechanisms of the vascular modulatory activity of hawthorn procyanidins .This effect may be achieved through inducing the influx of sodium and then activating the reverse mode of Na +-Ca2+exchange.

OBJECTIVE: Using the method of lactate dehydrogenase (LDH) assay, to observe the activities of rat cerebral microvascular endothelial cells (CMECs) intervened by Tongluo Jiunao Injection (TLJNI), a traditional Chinese compound drug removing toxin to dredge brain collaterals, and then further study the effects of different kinds of conditioned mediums (CMECs-CM) of cerebral microvascular endothelial cells on ischemia and ischemia/reperfusion cerebral cortex cells, and to probe into the drug pharmacological mechanisms of CMECs in modulating the neurons. METHODS: Three kinds of CMECs (normal, ischemic and ischemic/reperfusional) were all treated by TLJNI previously, and then the three pairs of CMECs-CM without serum were collected respectively for LDH assay. Rat cerebral cortex neurons were also primarily cultured and then divided into similar three groups (normal, ischemic and ischemic/reperfusional). The neuron responses caused by CMECs-CM at different concentrations were observed by using LDH transudation rate assay. RESULTS: The LDH release values of ischemic and ischemic/reperfusional CMECs with TLJNI treatment were obviously reduced (P<0.01) compared with the same kinds of CMECs untreated. For ischemic neurons, both conditioned medium of ischemic CMECs (Is-CM) and conditioned medium of ischemic CMECs with drug treatment (IsT-CM) in high concentration of 100% increased the LDH transudation rate (P<0.01), while in low concentration of 10%, IsT-CM reduced the transudation rate (P<0.05). For ischemia/reperfusion neurons, all kinds of CMECs-CM reduced the transudation rate respectively (P<0.05 or P<0.01). As far as each group concentration was concerned, 10% or 50% showed relatively stronger effects, and both conditioned medium of normal CMECs (N-CM) group and conditioned medium of ischemic/reperfusional CMECs (Rp-CM) group had statistical significance (P<0.05 or P<0.01). For normal neurons, all kinds of CMECs-CM increased the transudation rate respectively (P<0.05 or P<0.01). As far as each group concentration was concerned, only conditioned medium of normal CMECs (N-CM) had statistical significance (P<0.05 or P<0.01). CONCLUSION: The study shows that TLJNI is capable of preventing the damage of CMECs from both ischemia and ischemia/reperfusion states. Chinese drug can restrain the brain ischemia and ischemia/reperfusion damage by the media that CMECs modulate the neurons, demonstrating the pharmacological mechanisms of TLJNI. This work also indicates that there exist some active substances against ischemia/reperfusion injury secreted from CMECs-CM with TLJNI treatment.
