The study was conducted in Khanh Trung commune, Khanh Vinh district of Khanh Hoa province to assess the mosquito infection two years after DEC administration. Seventeen species of mosquito belonging to 5 genera have been found of which the main vector Wuchereria bancrofti was predominant. Indoor collection of Culex quinquefasdatus at daytime and nighttime was 3.5 and 2.3 individuals/house, respectively. Cx. vishnui was mainly found on the cattle sheds with an average density of 4.6 individuals/shed. A total of 578 mosquitoes of five species (Cx. quinqllefasciatus, An. vaglls, Cx. tritaeniorhynchus, Cx. vislznui, Cx. fuscocephalus) were dissected. None of them were positive with microfilaria.

This study was carried out on June 2004. Using the paper soaked in chemicals of WHO. Some insecticides, malathion 5% and Organophosphate Control; lambdacyhalothrin 0.05%, alphacypermethrin 30 mg/m2 and Pyrethroid Control. The test was applied by the method of WHO (WHO/CDS/CPC/MAI/98.12). The results showed that: Culex vishnui in Khanh Vinh district had a high resistance to some insecticides such as: malathion, lambdacyhalothrin and alphacypermethrin with the mortality rate of 13% - 17%, 19.7% and 23.7%, respectively

Study was carried out on 115 patients with breast cancer stage II, IIA who were treated by mastectomy and responded to scanlon at Hue Central Hospital. Results shơed that among them, 21.7% had metastatic recurrence by 5 years. The common recurrence was in chest wall (3.4%). There was relationship between metastatic recurrence and metastatic nodes under armpit. Metastatic recurrence was high when there were node metastasis under armpit with I, II degree. Metastatic recurrence related to clinical and histological period. Overall, 60-month survival rate was 68.2%. Patients with stage IIA have highest survival rate (85.7%). Metastatic lump under armpit related to survival time. 88.7% patients without metastatic lump under armpit had 5-year survival. The 5-year survival rate in patients with metastasis in degree I was 62,4%. The smaller tumor is, the higher 5-year survival rate is

The statistics from 1996 workers who directly working in 3 Textile - Garment Companies in Ho Chi Minh city (Phong Phu Textile Company, Southeast Company, Thanh Cong Textile - Garment Company). Results: the rate of male workers was higher of Textile branch. Almost workers’ health was classified as II & II (70.44%) types, male workers with health type I was more than female workers. The percentage of dental disease was highest (26.79%), then otorhinolaryngologic diseases (25.77%), gynecological disease (12.2%), eye disease, cardiovascular disease, hypertension, dermatosis etc… Bronchial - respiratory diseases accounted for only 0.72% but the most common was professional disease.

A prospective study was carried out to evaluate the severity of asthma by classification and to evaluate the GINA-based treatment. 102 asthma patients older than 1 year of age were classified in 4 steps of severity (GINA): step 1 (32 patients), step 2 (49 patients), step 3 (16 patients) and step 4 (5 patients). Most of asthma patients of steps 1 (31.4%) and of step 2 (48%) had slightly asthmatic symptoms and mildly affected lung function: PEF >80% (23.3%), moderately decreased PEF = 80% - 60% (57.5%). There were 1175 days of school-day or working-day loss. 32% of asthma patients had no specific treatment because of lack of knowledge; 48% of cases received an inappropriate treatment due to misdiagnosis and underestimation. 33.3% of patients used oral long acting β2 agonist (LABA) combined with inhaled corticosteroid (ICS); 25.4% of patients received inhaled LABA combined with ICS in our study; 66.6% of patients had lung function improved on 4th week of treatment

A measurement of arterial blood gas in the exacerbation of 54 patients with the chronic obstructive pulmonary disease shown that the arterial PaO2 was reduced in 20 patients (37%) and arterial PaCO2 was increased in 30 patients (55.6%). Among patients with the reduction of arterial PaO2¬, 14 patients experienced the respiratory failure, mainly type II respiratory failure. During the exacerbation of the disease, the arterial PaO2 reduction can occur in all 3 stages of the COPD.

Between April 1994 and May 1998, 90 patients with exacerbations of COPD were recruited in this study. Pulmonary ventilation was measured and evaluated using ATS criteria. The results showed that most of participants had combined ventilatory dysfunction (93.3%) and stage 1 or 2 of COPD (87.7%). 53.3% of patients were in stage 3 of COPD. There was not any relationship between FEV1 and chronic productive cough (r = -0.04). The instantaneous flow rates at different percentages of the FVC (MEF75%, MEF50%, MEF25%), PEF and PEF25-75% all decreased more than FEV1. There was not relationship between FEV1 and PEF, PEF25-75%, MEF75%, MEF50%, MEF25%. PEF was unreplaceable for FEV1 in diagnosis and monitoring COPD. After treatment, all these measurements increased partially (less than 15%).

Common bacteria on burn injuries are S. aureus, Enterobacter, P. aeruginosa, E. coli.... Rates of these bacteria infection vary between authors. Study on burn patients who hospitalized in the National Burn Institute between 6/1996 to 5/1997 showed that burn injury infection occurred in 100% of patients, with highest rate (100%) was seen in 1-3 days after burning, followed by period of 10-14 days after burning with the rate is 93.67%. The commonest bacterium is S. aureus (36.47%), followed by P. aeruginosa (29.18%). Infection rate of these bacteria combination was 18.35%. Rate of S. aureus infection was high in all 3 post-burning periods. Other bacteria were seen in periods of 5-7 and 10-14 days after burning.

Nitro compounds of eugenol were rarely described because eugenol derivatives with OH- and CH2=CH-CH2 groups in the molecular can be easy oxidated and polymerized on nitration reaction. The nitration of eugenol derivatives is an important reaction because the nitro group can be converted into a large variety of other functional groups. Eugenoxy acetic acid its methyl, ethyl esters were treated with HNO3 in CH3COOH to give dinitro eugenoxy acetic acid, methyl dinitro eugenoxy acetate and ethyl dinitro eugenoxy acetate. IR- and UV - spectra show that one nitro group replaces H at benzene ring, the other replaces H at alkyl group.

2 patients received the microsurgical flap. Both flaps has been living well, the functions were recovered well. The shape of face was relatively equal. The patients received a false maxila and teeth. The moving functions of the leg donated the calcaneal bone were well recovered without influencing the life. The conclusion: the defct of facio-maxillary area is a major lession that should be treated. The technique of microsurgery with using the calcaneal bone flap helps reconstructing the facio-maxillary area.
