There are 5 models of management for drug price currently in the world. Each model has combined with a private rule in order to stable drug price. In the situation of our country at the moment, we couldn’t apply one of among these methods. Some issues should be given priority as research of diseases model in practically and drug’s use, a tax system or fee for drug, promulgate of list of essential drugs needed in price’s management, an explanation of price should be given for a new drug and establishment of drug distribution system. In order to stable of drug’s price for a long term or in a certain duration, the key role is depended on the pharmacologist and the leaders of pharmacologic special management

Background: The postoperative residual spherical equivalent (SE) refractive error of the posterior chamber intraocular lens insertion is the cause result in significant distant vision loss. Objective: The study evaluated residual SE refractive error of the patients having ocular trauma undergoing a trans pars plana vitreo-lensectomy and posterior chamber intraocular lens insertion, for recorrection of the preoperative IOL power calculated formula are also investigated. Subjects: 43 consecutive patients who underwent a trans pars plana vitreo-lensectomy and posterior chamber intraocular lens insertion in the sulcus, in the Trauma Department of National Institute of Ophthalmology, from December 2005 to June 2007. Method: This was a prospective cross-sectional study. Results: Among 43 patients, there were 39 men and 4 women, age ranged from 10 to 45 years. In the most cases, the residual spherical equivalent deviation was planned to achieve final mild myopia (mean -1.75 D by manifest refraction; -1.9 D by autorefractor measurements). The surgery could provide a best corrected visual acuity at over 0.2 (81.4%). Conclusions: Intraocular lens implantation at the time of trans pars plana vitreo-lensectomy could provide a reasonable restoration of visual acuity and binocular function. However, recorrection of the IOL power calculation was necessary in these cases.

Introduction: Cataract and vitreous opacification caused by ocular injury results in significant visual loss. Objectives: to evaluate the initial outcome of patients with ocular blunt or penetrating trauma who underwent trans pars planar vitreo-lensectomy and posterior chamber intra ocular lens insertion. Comment on the indications and applications of surgical techniques. Subjects and method: In this prospective randomized study, a total of 30 patients (30 eyes) with blunt/penetrating ocular trauma were assessed using X-ray and ultrasound in the Trauma Department of National Institute of Ophthalmology, from December 2005 to August 2006. Results: 30 patients (28 men and 2 women) with an age range from 3 to 45 years. Penetrating injuries are more common than blunt ones. The cornea is the most common site of injury (73.3%). Conclusion: Intraocular lens were implanted at the time of trans pars planar vitreo-lensectomy can provide a reasonable restoration of visual acuity and binocular function.

Background: In the period 2006-2010, a investigation on medical arthropod has been conducted\r\n', u'Objective: 1) To determine species composition and distribution of medical arthropod. 2) To find species transmitted disease \r\n', u'Subject and method: The cross sectional, descriptive and analytic investigation was conducted in 3 communes along the Ho Chi Minh road in Cao Bang province. \r\n', u'Results and conclusion: : A total of 3.437 of samples of medical arthropod belonging to 96 species have been collected including: three species of flea (Siphonaptera), two species of tick (Ixodoidea), four species of chigges (Trombiculidae), ten species of mites (Gamasoidea), twenty four species of flies (Muscoidea), and fifty-three species of mosquito (Culicidae). They belong to 39 genuses, 17 families, 3 orders: (Siphonaptera, Acarina and Diptera); two classes (Insecta and Arachnida). \r\n', u'Some species having epidemiological role such as Aedes albopictus, Culex tritaeniorhyncus, Cx. quinquefasciatus, Cx. vishnui ... were predominant at all study sites. Anopheles minimus, the main malaria vector, was mainly collected in cattle- sheds in Truong Ha and Bach Dang communes. \r\n', u'

Background: Japanese Encephalitis (JE) is common in the plains and mountainous areas in Asia \u2013 Pacific. Japanese encephalitis vaccine shows effectiveness in protecting children from JE in some countries such as Japan and Korea. Objective: To evaluate the efficacy of Japanese Encephalitis (JE) vaccination in Thai Binh province during 2003-2007. Subject and Method: Prospective, retrospective and sero-epidemiological methods were carried out on 329 samples collected from viral encephalitis patients and tested by JE MAC-ELISA, the positive average was 41.6% (137/329). Result: It had dramatically dropped from 85.2% in 2003 to 8.5 % in 2007 related to the rate of JE vaccination for children from 1 to 5 years old increasing from 49 % in 2003 to 77 % in 2007. Most of JE confirmed cases were un-vaccinated. Conclusion: JE etiology cause viral encephalitis in children in Thai Binh province was reduced thanks to JE vaccination in EPI program for 1 to 5 year old children. But more than 96% (131/136) of viral encephalitis in 15 years old upward was unknown etiology, the need for further study of the etiology cause viral encephalitis in adults.

OBJECTIVES: To objectively determine and compare the physical activity (PA) levels of adults newly diagnosed with type 2 diabetes (T2D) and adults without T2D in Vietnam using an accelerometer. METHODS: A total of 120 participants with newly diagnosed T2D and 120 adults without T2D were recruited from a large hospital in Hanoi, the capital city of Vietnam. All participants wore an ActiGraph GT3X accelerometer for at least 5 days, including 1 weekend day. Freedson cut-off points were used to estimate different intensities of PA. In addition, comparisons between groups were made with respect to achieving the World Health Organization (WHO) and International Diabetes Federation (IDF) recommended PA guidelines. RESULTS: Men with T2D had significantly lower levels of PA than men without T2D. The respective multivariable-adjusted mean values of daily step count, daily light-intensity, moderate-intensity, and moderate-to-vigorous-intensity PA were approximately 14%, 19%, and 22% lower in the men with T2D than in their non-T2D counterparts. However, women with T2D accumulated a greater number of steps per day than women without T2D. Only 59.2% of the adults with T2D met the minimum recommended level of PA (WHO and IDF), compared to 74.2% of adults without T2D (p<0.05). After adjusting for potential confounders, participants with T2D experienced 50.0% significantly lower odds of achieving PA recommendations. CONCLUSIONS: Vietnamese men with T2D were less physically active than those without T2D, and adults with T2D were less likely to meet PA guidelines. The results suggest a need for integrating PA into the self-management of this chronic condition.

Several factors presumed to facilitate the transmission of Taenia spp. were reported in Vietnam. We conducted a cross-sectional study taking questionnaires from 1,185 participants, and collecting 1,151 sera and 1,036 stool samples in northern Vietnam. Sera were examined for circulating antigens of Taenia solium cysticerci using ELISA, stools for Taenia eggs by Kato-Katz smear, and copro-antigens by ELISA. Ag-ELISA revealed 4.6% antigen positivity, indicating infection with viable cysticerci. Taenia eggs were detected in 1.5% of participants. Copro-antigens were found in 2.8% of participants. Eating raw meat and/or vegetables was significantly associated with the presence of copro-antigen (OR=8.6, 95% CI: 1.16-63.9, P=0.01). Considering the high taeniasis prevalence and the associated threat, public health attention should be given to treat the tapeworm carriers in the projected areas.

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.
