In duration of 11 months (12/1999-10/2000) 22 case of carotidocarvenous fistula (CCF) have been confirmed by angiography. 18 patients were treated by endovascular method with 17 procedures performed with detachable balloons. The remaining case was done using coils. Results of the 18 patients who underwent endovacular methods, caroticocavenous fistulae in 17 patients resolved completely. Two patients needed additional session which likewise showed good results. There is one failed case which is still awaiting for another interventive session.

A retrospective study on patients with the liver cancer treated by alcohol injection under X-ray monitoring in the Brabois Hospital + Center for University - Institute in Nancy was carried out to evaluate the advantages, limitations and efficacy of the treatment. The results showed that the advantages were rapid, correct, and easy to inject in to the small tumor and radical treatment. The limitations were to have X-ray with C lamp. This method was only effect in combination with other methods.

The measurement of parameter of the aorta, renal left and right arteries of 40 normal people with ages of 20 - 40 has shown that the parameters of indicators of Doppler in the normal Vietnamese were an insignificant different from these in normal English, French. The parameters of Vp, Vd and Vm were different between the left and right, and between proximal and distal position of the renal artery. The parameters of ACT, RI, PI, ATR, RAR were not different between right and left as well as position of the renal artery

Background: Dihydroartemisinin 40mg and piperaquine phosphate 320mg (DHA-PQP) drug combination and piperaquin phosphate (PQP) material was first successfully produced in Vietnam \r\n', u'Objective: to study influences of the fixed combination antimalaria drug dihydroartemisinin plus piperaquine in reproductive progress of mice\r\n', u"Subjects and methods: This study was carried out at the Department of Malaria treatment and research, National Institute of Malariology, Parasitology and Entomology (NIMPE), between September, 2006 and March, 2007. The influences of the fixed combination antimalarial drug 40 mg dihydroartemisinin (DHA) plus 320 mg piperaquine phosphate (PQP), with PQP produced firstly in Vietnam, in mice's reproductive progresses were investigated in three generations (including the parent and FI, F2 child generations). \r\n", u'Results: In all three generations, study indices among the treated and control groups were not significantly different (the values P > 0.05). These indices included the rate of fecundation, numbers of fetuses of each mother mouse, numbers of offspring of each mother mouse, mean body weights of offspring. Early lethal fetuses, lately lethal fetuses, monsters and innate abnormally offspring were not found in P, FI and F2 generations. The necessary feeding - day numbers that offspring of P and F 1 generations reached their body weights about 20g were different insignificantly (the values P> 0.05) among the treated and control groups. \r\n', u'Conclusion: The combination DHA-PQP was found to cause no genome mutations in mice at the oral dose of 120 mg per kg per day for 5 consecutive days. \r\n', u'

Background: Piperaquin (PQ) is an anti-malaria drug, which belong to bisquinoline class. Vietnam has successfully produced PQ (both base and phosphate) since 2004. Objective: To evaluate acute oral toxicities of Piperaquine phosphate and the fixed combination anti-malarial drug Dihydroartemisinin plus Piperaquine in mice. Subject and Method: This study was conducted at National Institute of Malariology, Parasitology and Entomology between June and October, 2005. The acute oral toxicities of piperaquine phosphate (PQP) and the fixed combination anti-malaria drug (40 mg dihydroiutemisinin plus 320 mg piperaquine phosphate (DHA-PQP), with the materials produced by Institute of chemistry) in mice were investigated. Result: PQP had a medium toxicity. Inhibition of mice's central nervous systems was the main toxicity exhibition. At the high doses of PQP, mice's convulsion was observed before their deaths. The infralethal dose (LDo), absolute lethal dose (LD100) and mean lethal dose (LD50) of PQP were 900, 2300 and 1643.98 (1537.6 \u2013 1758.92) mg/kg, respectively. The fixed combination DHA-PQP had a less toxicity than PQP powder, with LDo, LD100 and LD50 were 1400, 2800 and 2050.06 (1943.63 \u2013 2157.14) mg per kg of body weight, respectively. Conclusion: At the high doses of DHA-PQP, this combination also inhibited mice's central nervous systems. Mice convulsed strongly before their deaths. All died mice were operated for observing visually their organs such as hearts, livers, kidneys, lungs, vesicles and intestines. No abnormal signals were found.

Background: The combination of dihydroartemisinin and piperaquine is interested because of its efficiency and safety in treating malaria. Objective: To evaluate the influences of the fixed combination anti-malarial drug dihydroartemisinin plus piperaquine in constitutions and some biochemical and haematological indices of rabbits. Subject and Method: The sub-chronic toxicity of the fixed combination anti-malarial drug of 40 mg dihydroartemisinin plus 320 mg piperaquine phosphate (DHA-PQP), with the materials produced by Institute of Chemistry, in rabbits was investigated. Rabbits were treated daily by oral route with DHA-PQP at the dose regimens of 64 and 100 mg/kg per day for 28 consecutive days. Result and Conclusion: DHA-PQP did not affect on rabbits' constitutions. Generally, all rabbits had normal ingestions, activities, and defecations. Rabbits' body weights increased regularly along the study period and significantly increased between day 28 and day 0 (P < 0.05). At the dose regimen of 64 mg/kg per day for 28 consecutive days, DHA-PQP did not change significantly rabbits' biochemical indices (including GOT, GPT, bilirubin, creatinine and protein) and haematological. These changes were insignificantly different between the treated and control groups at the same study points (P > 0.05). With the dose regimen of 100 mg/kg, the combination did not affect significantly (P>0.05) on some rabbits' biochemical and haematological indices. But hemoglobin, erythrocyte count and rate of monocytes increased significantly on day 14 comparing to that the control group (P < 0.05) and became in normal limits on day 29 (P > 0.05). Protein concentration also increased significantly on days 14 and 29 comparing to that of day 0 (P < 0.05).

The optimal condition for Moringa oleifera root barks extraction was determined using response surface methodology and Box-Behnken Design. The actual optimal condition of the factors was 65 o C, ethanol 60%, 40 (mL/g) liquid-to-solid ratio with 240 minutes extraction time. The enrichment of phenolic compounds sharply affected the antioxidant, and inhibitions of α-amylase enzyme, as well as, the anti-inflammatory effect of the extract from M. oleifera root barks. The extract in the optimal condition exhibited better 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging and α-amylase inhibitory activities than those of positive controls.Also, the extract showed weak hydroxyl free radical scavenging and nitric oxide (NO) production inhibitory effects. These revealed a simple and promising method for the preparation of bioactive products from the root bark of M. oleifera.
