Aims: Herbal and medicinal plants bioactive compounds of Jatropha curcas, Piper nigrum and P. betle have been shown to possess therapeutic properties. This study investigates the presence and characterization of phytochemical compounds as well as to evaluate the antimicrobial activities of the methanolic crude extract of the leaves and seeds of J. curcas, P. nigrum L. and P. betle. Methodology and results: The study on antibacterial and antifungal efficacy of the crude extracts of leaves and seeds were carried out using standard disc diffusion method. The crude extracts were found to exhibit an average response of antimicrobial activity with the inhibition zones ranged from 3% to 28% for antibacterial and from 21% to 79% for antifungal activity. Among all extracts, the leaf extract of P. betle showed a good antibacterial activity against Staphylococcus aureus and excellent antifungal properties against Aspergillus niger and A. flavus. The phytochemical screening analysis revealed the presence of saponin, tannins, glycosides, terpenoids, reducing sugar, flavonoid and anthraquinones. However, phlobatannins was not present. Total phenolic content (TPC) and total flavonoid content (TFC) were highly detected in the crude extract of P. betle and recorded as 13.33 mg of gallic acid equivalents, GAE (mg/ 100 mg sample) and 0.88 mg of RE (mg/100 mg sample), respectively. GC-MS analysis of the bioactive compounds reveals the presence of diethyl phthalate, 2-hexadecen-1-ol (Phytol), hexadecanoic acid, piperine, phenol and other minor compounds. Conclusion, significance and impact of study: The study suggested that P. betle has a potential as a source for antimicrobial agent from plants extracts. Nevertheless, further studies are needed to elucidate their precise mechanism of action.

Plication of horizontal recti with many advantages in the treatment of strabismus has been applied by many authors in the world, but not yet in Vietnam. Objectives: to evaluate the results of this surgery that applied in Vietnamese. Methods: Prescriptive, longitudinal prospective study that had been done in Hanoi National Institute of Ophthalmology from 9/2003 to 9/2004. Results: In postoperative period, 83.3% of cases with exotropia and 89.6% of cases with esotropia are well corrected after 6 months, 100% of operated eyes are well healed with a smooth conjunctive scars and 52.62 % of operated patients have got a full binocular vision after 3 months following up. The rate of the eyes with suspected amblyopia is reduced from 18.8% to 9.8%, with moderate amblyopia is also reduced from 8.8% to 2.4% by 6 months postoperatively, but the rate of the eyes with severe amblyopia is not significantly changed after surgery. Conclusion: Plication of horizontal recti is a safe, effective method for correction of strabismus, especially when it is necessary to do surgery on many extra-ocular muscles in the same eye.

Retrospective study from January 1999 to October 2003 on 90 patients of acute necrotizing pancreatitis (ANP) treated at Viet Due Hospital in which demonstrated: male patients represented 56.7%; alcoholism 18.9%. The interval between onset syndrome and operation was: less than 48 hours: 14.4%; from 2 to 14 days: 74.4%; more than 14 days: 11.2%. Surgical procedures were performed: resection for the necrotic tissue and ample drainage (86 cases), pancreatectomy of head part and main part was done on 2 cases, abscess drainage for 2 cases; jejunostomy: 67 cases; biliary: 53 cases; management of other lesions for 3 cases; postoperative complication was presenting 35.6%; the mortality was 18.9%. This study showed that necrotizing pancreatitis did not well respond to medical treatment. The best time to take operation is on the third day still onset the syndrome. The surgical procedures as resection for necrotic tissue and drainage is most often management. Ample pacreatectomy is not employed due to it cause high mortality, can be up to 100%. Regarding patient nutrition, the jejunostomy is more effective and it can control infection as well. The biliary drainage can be indicated if bile duct was obstructed.

A study on the current status of malaria and the efficacy of interventions among migrants was carried out in one district with high malaria transmission in Central Highland - Vietnam from 2002-2004. The findings of the study showed that: The malaria prevalence of clinical and parasite were high in the migrant, especially among new comers (clinical rate: 5.2% and parasite rate:4.3%). These rates were higher than that in local people (clinical rate:5.0% and parasite rate: 3.1%) and were still high in the year 3 and decreasing after 3 years. The applied interventions for migrant were: strengthening of the health education, improvement of community health workers and they were effective. The prevalence and incidence of malaria were reduced from 3.9 to 0.65% and 45.3 to 28.1/1000 population, respectively, after 3 years. The malaria rate was reduced by 40-60% compared with that in the control group.
