BACKGROUND: Naomaitong injection is a Chinese herbal compound preparation for treatment of ischemic cerebral vascular disease, acting on resisting calcium overload, regulating the imbalance between thromboxane (TXA) and prostaglandin (PG) and blocking lipid peroxidation mediated by free radical so as to protect cerebrum.OBJECTIVE: To observe the effects of naomaitong injection on water and Ca2+ contents, activity of superoxide dismutase (SOD), levels of lipid peroxide (LPO), 6-keto-PG lα and TXA, and compare it with danshen injection.DESIGN: Randomized control experiment was designed.SETTING: Experimental Center of Chengdu University of Traditional Chinese Medicine.MATERIALS: The experiment was performed in Experimental Center of Chengdu University of Traditional Chinese Medicine from October 1997 to February 1998, in which, 72 healthy male Wistar rats were employed, rangroup: Abdominal injection was done with physiological saline 1.67 mL/kg,group): Abdominal injection was done with compound danshen injection groups (naomaitong No.1, No.2 and No.3 groups): abdominal injection was done with naomaitong injection 3.33, 1.67, 0.84 mL/kg successively,twice/day.METHODS: Totally 48 hours after medication, under anesthetized state,the rats in every group were sacrificed to collect brain tissue. The two hemispheres were cut into two pieces from the middle. One of them was prepared into brain tissue homogenate at low temperature. Radioimmunologic analysis method was used to measure 6-keto-PG 1o and TXA B2 levels so as to evaluate the balance between PG and TXA systems. The modified pyorgallol autoxidation and thiobarbituric acid (TBA) colorimetric method were applied to determine SOD activity and LPO level respectively so as to evaluate lipid peroxidation mediated by free radical. The dry and wet weights of other piece were weighed immediately on electronic scale and the water content of brain tissue was calculated to evaluate brain edema. Atomic absorption spectrophotometry (AAS) was used to determine Ca2+content in brain tissue so as to evaluate calcium overload.tissue of rats in every group.content in brain tissue of rats in every group: That in model group was higher remarkably than normal group [(82.27±1.32)%, (77.24±1.36)%;(267.47±15.69), (37.55±13.23) μg/g, P < 0.01]. The water contents in 4 treatment groups were decreased of various degrees. The effect in No.1 group was the strongest [(78.74±1.41)%] and that in danshen group was the weakest [(81.45±1.52)%]. Ca2+ content in danshen group was decreased of various degrees, indicating dose-effect dependence, but, which was near to ty and LPO level in brain tissue of rats in every group: SOD activity in model group was lower remarkably than normal group [(86.18 ±3.17),(131.86±4.67) μkat/g, P < 0.01]. After treated with naomaitong of 3 dosages, that was all improved, indicating dose-effect dependence (P < 0.01). The effect of No.1 group was the strongest [(119.02±4.00) μkat/g],SOD activity in danshen group was near to model group (P > 0.05). LPO level in model group was higher than normal group [(52.46 ±3.25),(32.29±2.23) μmol/L, P < 0.01]. LPO level of every treatment group was lower significantly than model group and the therapeutic effects of No. 1, 2,3 groups were superior to danshen group [(35.68±2.86), (41.54±2.47),1α and TXA B2 in brain tissue of rats in every group: Content of 6-ketoPG 1α in brain tissue of model group was lower remarkably than normal group (P < 0.01). That was improved in all of 4 treatment groups, in which,the therapeutic effects of No.1, 2, 3 groups were superior to danshen group [(43.84±2.98), (35.01±4.32), (29.97±3.81), (22.89±3.64) ng/g, P < 0.01].TXA B2 content in brain tissue of model group was higher remarkably than normal group (P < 0.01). After treatment, the 4 treatment groups lowed significantly TXA B2 content in brain tissue compared with model group,indicating dose difference. That in danshen group was lower than No. 1, 2,3 groups [(40.58±1.34), (32.85±1.43), (34.31±1.39), (37.27±1.52) ng/g, P <0.01].CONCLUSION: Naomaitong injection alleviates brain edema, resists calcium ion, regulates imbalance between TXA and PG systems, improves activity of anti-oxidase and is against injury of free radical so as to protect the structure of brain tissue and achieve therapeutic effects, indicating a certain dose-effect relationship. The effect of naomaitong injection is superior to that of compound danshen injection.

Journal of International Oncology 2012;39(6):455-458
Thrombosis disease is a common complication of cancer. Researches show that venous thromboembelism ( VTE ) can increase the mortality rate of patients with cancer.Tissue factor (TF) and cancer procoagulant (CP) and other pathological factors are related to VTE.VTE risk factors in cancer patients can be grouped into 3 general categories:patient-related factors,cancer-related factors and treatment-related factors.Assessment of risk factors and early prevention can reduce the incidence of VTE.Immediate treatment and chronic therapy should be performed immediately after the diagnosis of VTE.
