The randomized Controlled Trial is the standard design to prove the effectiveness of drugs or other forms of interventions. In this type of clinical research, individuals are randomly assigned (randomization) to either of the two or more groups, one with the intervention the other without the intervention being tested or another intervention. When done properly, it can provide the best evidence of effectiveness

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.

his technique was performed on 50 patients with congenital dilatation of the bile duct including 35 females and 15 males, ranging in age from 3 months to 33 years old. Patients treated from 4/1996 to 6/1999 at the Pediatric Institute and at the Bach mai Hospital, with abdominal pain in 76%, jaundice in 58%, classic triad in 12%. The diagnosis and the indications for operation have based on the ultrasonography.The cyst flattened by bile suction and the intraoperative cholangiography was very useful for the dissection, the resection of cysts and the performance of the anastomosis. There were not particular difficulties to prepare a jejunal segment about 25 cm in length, 40-50 cm from Treitz, passing through a hole made in the transverse mesocolon and duodenum. 35 intussusception valves were made in the isolated loop of jejunum. There was no mortality. Only 1 case with infected wound and another case with the left underdiaphragmatic abscess caused by the leakage of the jejuno-jejunal anastomosis, successfully treated by the drainage of the abscess. All the patients normally discharged from the hospital

38 patients (18 males, 20 females), age from 17 to 61 years, were assigned in two groups. Group 1 including 29 patients (53 eyes), vratisolin 2% ophthalmic ointment was applied 4-5 times daily into the conjunctive sac. Group 2 including 9 patients (15 eyes), Ofus ophthalmic eyes drops was used 10 times daily. Results: in patients with epidemic conjunctivitis, treated by Vratisolin, more rapid reduction of symptoms was observed in comparing with this the group treated with Ofus eye drops.

Maduxin ointment is totally extracts from the leaves of the Maduca pasquieri and has been applied in burn treatment in Vietnam since 1987. We studied the effects of Maduxin on the collagenization at burn wounds by following up the changes of OH-Pro content at slaked lime burn wounds - a popular type of burn in Vietnam in comparison with the effects of SSD in burn treatment. Our study was carried out in 21 slaked lime burn patients who were treated at the Vietnam Burn Institute from May to September 1997. The results indicated that OH-Pro concentration increases related to collagen synthesis during the burn wound healing. In the slaked lime burn wounds treated by Maduxin OH-Pro level in burn tissue increases more than in the wounds treated by Silvesufadiazin during the healing.

Study was carried out on 80 mechanical energy menorrhagia patients under 18 years of age, treated with rigevidon combined with preventive antibiotics and commonly drugs as oxytoxine, ecgometrine at the Newborn & Mother Protection Hospital in 2000. The results showed that: with single dose of 2 tablets per day, taken in unique time in the evening, and then reduction of dose to 1 tablet per day when bleeding stopped, to make a 28 days menstruation cycle, the good efficacy was observed in 96.25% of patients (77 patients respond well to treatment). After, maintain treatment for 3 months following to make an artificial menstruation cycle then stop completely. All of patients had no any seriously complications, including menorrhagia after stopping treatment

Objective: to study the ability of cedemex in preventing the spirit dependence (anti readdiction). Animals and method: using the method of position taste with condition to establish the model of spirit dependence to morphine in white house- mouse. Results: Among the mice taking continuously cedemex by 5 days, with 3 different doses, then using hydrocortisone to stimulate, the residence time in white boxes did not last clearly, the behaviour toward preferring white boxes was not recovered and it returned to position state without condition. But in morphine group when using NaCl 9%o, the residence time in white boxes did last clearly, the behaviour toward preferring white boxes was recovered.

One of the challenges for the current malaria management in the province of Thua Thien - Hue is imported malaria caused by the movement of population across the Vietnam - Laos border and between the malaria endemic areas from Quang Nam to Quang Tri provinces by the newly constructed route of Ho Chi Minh. Under that circumstance, the active measures have been set up for control and prevention of malaria infection, especially for risk cases. These measures appear to be initially effective. The incidence, fatality has been controlled. The risk of imported malaria has been over. However, those measures need to be sustained in the border areas and the Ho Chi Minh route to maintain the achievements

A randomized controlled trial was carried out on two groups of patients who were received either Flagystatine (nystatin 1000000 UI/metronidazol 500 mg) or Neo Penotran (miconazol 100mg/metronidazol 500 mg), twice a day for 7 days. Gynecological and microbiological assessments were carried out before treatment and 14 days after the first visit. In Flagystatine and Neo Penotran groups, clinical cure rates were 42% and 77.9% respectively; microbiological cure rates were 68.2% and 72.1%. In Neo Penotran group, functional symptoms were reduced more than organic symptom (84.8% and 79.1%, respectively). This difference was not so remarkable in Flagystatine group (64.8% and 65.95, respectively). Side effects of Neo Penotran were insignificant. Neo Penotran therapy without supportive treatment had higher efficacy in vaginitis at dosage of two pill a day in 7 days. The drug showed effects in both of function symptoms and organic symptoms, in clinical and paraclinical
