Yao et al demonstrated that, lysine also exerts protective effect against the isch-emiclesion of brain. Meanwhile, vitamin C is a natural antioxidant, which has undisputable protectiveaction against free radical damages. In order to ascertain whether their combination could affordbetter effect, we have investigated the prophylactic effect of the couplant ascorbate-lysine inliver injuries.展开更多

MethodsMoclobemide sustained release tablets were given as a multiple oral dose regimen of 300 mg oncedaily for five consecutive days to 12 healthy volunteers. The concentrations of moclobemide inplasma were determined by reversed-phase high performance liquid chromatography. The partialpharmacokinetic parameters were calculated using 3p97 pharmacokinetic program. Results Theconcentration-time profile fitted an one-compartment model best. The steady-state pharmacokineticparameters of moclobemide sustained release tablets after multiple oral doses were as follows:C_(max) was (1 950 +- 156) μg· L^(-1), T_(max) was (6.00 +-1.55) h, T_(1/2(kel)) was (3.14 +-0.12)h, AUC_(ss 0-24) was (22 836 +- 1 842) μg·h· L^(-1), MRT was (7.68+-0.36) h, CL/F_((s)) was(20.2+-2.1) L·h^(-1), and V/F_((c)) was (91.4+-9.4) L, respectively. No marked adverse events werenoted during this study. Conclusion The formulation has a sustained-release effect and goodtolerance in the healthy volunteers, which provides useful information for clinical practice.展开更多

Methods: High-performance liquid chromatography-ultraviolet detection method was used in this study. Results: The pharmacokinetics of Ginsenoside Rg3 in 14 healthy volunteers were investigated. After a single oral dose of 3.2 mg.g-1 Ginsenoside Rg3 in 8 male volunteers, the plasma concentration-time course fitted in well with a two-compartment open model, with the following pharmacokinetic parameters: Tmax 0.660.10 h, Cmax 166 ngmL-1, T1/2a 0.460.12 h, T1/2b 4.91.1 h, T1/2(Ka) 0.280.04 h, AUC0-∞ 7726 ngmL-1h, respectively. No kinetic analysis was made after an oral dose of 0.8 mg.g-1 Rg3 in other 6 volunteers because of the low concentration, but there was a good correlation between Cmax and dosage of the two groups. Conclusion: The absorption of Rg3 was rapid in the human body, and its elimination was rapid too after oral administration of Ginsenoside Rg3. The pharmacokinetic results shows that it exhibited the first-order kinetic characteristics.展开更多

The Cmax of diclazuril in solid dispersion and premix were 33.72±4.75 μg/mL and 10.42±3.4μg/mL, respectively, The t1/2 were 9.53±1.37 and 9.23±1.20 min, respectively. The oral bioavailability of drug solid dispersion was 1.7-fold higher than that of premix. From these data we concluded that diclazuril solid dispersion may be used as a potential anticoccidial preparation.展开更多

Methods： Sixty two patients were randomly divided into a treatment group （32 cases） and a control group （30 cases）. Acupuncture at Baihui （GV 20）, Fengchi （GB 20）, Shuaigu （GB 8）, Xingjian （LR 2）, Neiguan （PC 6）, Sanyinjiao （SP 6） and Ashi points combined with oral administration of Chinese herbal decoction, was applied in the treatment group, and simple oral administration of Chinese herbal decoction was applied in the control group. Results： The total therapeutic effect in the treatment group was better than that in the control group （P〈0.05）. After treatment, the frequency, and duration of the attacks were reduced and shortened, and headache greatly alleviated in both groups （P〈0.01）. The alleviation in the treatment group was more obvious than that in the control group （P〈0.05）. Conclusion： Acupuncture combined with oral administration of Chinese herbal decoction provided remarkable therapeutic effects in treating vascular headache.展开更多
