The study was conducted at Hanoi Obstetrical and Gynecological Hospital, combining quantitative and qualitative research methods. Results: the study showed that there was a tendency for pregnant women to over-use ultrasound scanning. The reasons for this included women’s perceptions of the usefulness of ultrasound scanning, their serious worries for the fetus, as well as the effects of the market economy on this health service. Over-use of obstetrical ultrasound scanning was not only related to the perception, demands and psychology of pregnant women, but also to socio-economic changes associated with the economic reforms and the liberalization of the health care system.

Our research was carried out on 133 occupational carbon monoxide exposed workers in a metallurgical factory. The results showed that carbon monoxide concentration in some working places was higher than the allowance limit from 1.4 to 5.3 times. 77.2% indoor environment was polluted by substances coming from factory. This pollution had influenced on the health of 35.3% of workers (influence on nervous, circulatory, respiratory, digestive systems and anemia,..) 16.5% of the cases suffered from occupational carbon monoxide chronic clinical poisoning. The occupational acute carbon monoxide poisoned anamnesis at the factory was 7.3%.

The investigation was done in 74 occupational carbon monoxide exposed workers in a coke factory. The result showed that carbon monoxide concentration in some work places was higher than the allowable limit from 1,2 to 5 times. 70,3% workers' indoor environment was polluted by substances coming from factory. These pollution had influence on the health of 47,2% workers (influence on nervous, circulatory, respiratory, digestive systems and anemia etc.). 1,4% of the cases suffered from occupational carbon monoxide chronic clinical poisoning.

An interview of 245 people of which VÜnh Phóc (52), Nam Hµ (49), H¶i H­ng (50), L©m §ång (23), S«ng BÐ (40) and Sãc Tr¨ng (41) has shown that the use of contraceptive pill has been limited until the time of interview. There was a lack of supervision in the implementation of control table for user. The control table actually contributed to simplify the process of pill dispensing and facilitate to users. The control table also provided fully the information of contraceptive pill such as administration and over coming the wrong knowledge of users.

At the first step of studying about “the volume of cord blood” in Vietnamse, a total of 50 samples have been collected. We obtained some results: - The mean volume of cord blood was: 50.06 +/- 20,73ml. -The mean number of total mononuclear cells was 352.4 +/- 161.6 (x106). -Some cord blood colections had many total MNC as some larger cord blood harvests. So, it is our belief that total MNC numbers are more useful indicator of clinical utility than more sample volume.

During the five-year period of 1991-1995, there were 840 children suffered from primary nephrotic syndrome including 52 of acute renal failure with a frequency of 6.19%. In treating, 35.72% of patients got a most rapid decrease of oedema, 66.67% remained lasting oedema, 19.23% got a urine volume restored after 3 days. Before the treatment, hypertension occupied 44.68% and after treatment 27.68% of patients. In 52 studied patients, good response to the treatment occurred in 44 (84.62)%, 8 (15.38%) got the chronic form of renal or died. In regard to laboratory data, in patients with light decrease of blood albumin level, renal function were well restored, while with large decrease, it was worse even could be transformed to chronic or deadly form. In 90% of patients, the BUN/blood creatinine ratio was 20

The bacillary dysentery can occur in all age but rarely in children under 6 months in the pediatric department of Bach mai Hospital had a warning in the food hygience and safety and drug administration for infant. The first baby was treated by Negram in the condition of disease free. The second baby was treated by Negram in the fifth day, within 2 days and discharged in the condition of disease free.

This study was carried out in 72 healthy adults of working age, non-smoking, and non-exposure to occupational carbon monooxide. The results showed that substances coming from factories did not pollute their indoor environment at home. The hemoglobin (Hb) contents of examined persons was within the normal range of 122-165 g/l. Average CarboxyHemoglobin (HbCO) was 0.789+/-0.382%, ranging 0.000 to 1.500%.

Study on the pathogens of septicemia in order to choose appropriately antibiotics in the treatment. Subjects were 138 septicemia patients admitted to Institute of Infectious and Tropical Diseases from June 2001 to May 2002. All patients were taken their blood samples to isolated and culture bacteria during they had high fevers or before taking antibiotics. Some pathogenous bacteria were isolated and identified in 20.3% patients. The most common species were S. aureus (accounted for 42.4%), followed by Enterobacteriaceae (28.8%)

Prospective clinical trial on two groups of patients: one treated with amitryptyline and the other with diantalvic. Results: At the beginning of study, no difference in the severity of pain in both groups. Group 1 had more effective to control pain than group 2. After one week of treatment, group 1 had one case (3.3%) while group 2 had 15 cases (35.7%) didn’t have any improvement. Amitriptyline had more advantages that Diantalvic to treat the postzosterian pain
