From December 2000 to March 2003, at Huu Nghi Hospital, 85 patients with tracheal intubation were studied. There was no statistically statistic significances between 2 groups (of success and of failure) concerning the age, predicted body mass, the duration of mechanical ventilation. The causes of respiratory deficiencies needing mechanical ventilation were: infections, cerebral infarctus, cerebral hemorrhagy, acute left heart failure, acute myocardiac infarctus, diabetes. CROP diagnostic value of weaning from mechanical vetilation was higher in success group than in failure group. Threshold value of CROP index  13 (ml/breathing rythm/minute) had got a sensitivity of 0.65, specificity 0.89, predicted positive value 0.84, negative 0.74, under curb surface ROC = 0.875.

To survey the basic measurements of urodynamic as cystometry, uroflowmetry, electromyography, urethral profilometry. Currently, it may be to combine measurements each other or urodynamic with image diagnostic technique in order to have comprehensive consideration, more accurate on lower urinary tract function: To combine with cystometry, uroflowmetry and electromyography, detrusor pressure measurement, to combine with cystometry and observe reflection of light of cystoids under fluorescent screen, video-urodynamics

Varicocele is a dilatation of plexus venosus in the spermatic cord. It rarely occurs before the age of puberty, but 15% of male teenager experienced varicocele (the rate is relatively high). This rate is higher when surveying data of male infertility (35% of primary infertility patients, and 75-81% of secondary infertility patients had experienced varicocele). Varicocele may affect both sides, but 90% of cases occurred in 1 side and among them 90% were in the left side. Microsurgery is a treatment with high rate of success

A statistic investigation was conducted on all species of animals as a whole with their distribution, their status of existence up to the year 2003.There are 408 species including 22 classes, 6 branches of animal which had been used and had been identified in Vietnam. Among them, 393 species have been living in wild nature, their 152 species were registered into Vietnam’s Red Book. According to the APPENDIX of The Decree n.48/2002/ND-CP and The Appendix of CITES_ Guide to Plants and Animals in Trade, Authors had Recommended the use of breeding animals instead of wild animals

Study was carried out on 22 HBsAg positive outpatients (14 males and 8 females, over 19 years old), all of them hadn't received any drug for hepatitis and HBV vaccine, and were treated at Central Military Hospital 108. All patients were treated with syrup of Hebevera 40ml twice a day. Results: syrup of Hebevera had possibilities of clearing HBsAg, HBeAg in patients' serum, stimulating immune system to produce antiHBe, protecting hepatic cells against necrotic inflammation, normalizing high ALT and AST. Beside, syrup of Hebevera has broad indications, no side-effects, and easy to use

Antibiotics were studied and has been used for a long time, and this medicine more and more develops and renovates. Antibiotics were renovated and classified. According to current definition, antibiotics are all natural mixes, semi-collection or collection with antibacterial effect. According to this definition, antibiotic is classified: Antibiotic is natural mix (including six main groups); semi-collective antibiotic, collective antibiotic. Changes in each antibiotic group has been studied. Authors also investgated collective antibiotic in this topic. In addition, main problems are currently solved: toxicity and allergy of some antibiotics, antibiotic resistance, probability happening when using mixture of many antibiotics (via simple combining effect or antagonistic effect)

3 cases of intracranial aneurismal residue following clipping at Viet Duc Hospital were studied. The causes of this condition were anatomical and technical. It is necessary to identified prior surgery the cause of hemorrhage, to limit the disruption of aneurism, to expose entirely the neck of aneurism before the setting of clip and to explore throughly the place of clip- Anterigraphy or systematic Xray control should be made for checking the results

The clinical manifestations, the endocrine examinations and imaging features (MRI) of 91 patients with pituitary adenomas who had undergone transsphenoidal microsurgery from 1/2001 to 6/2003 were analyzed. The patient population was 49.5% female and 50.5% male. Mean age was 40.4 years.71 patients (78%) experienced decreased visual acuity, 67 patients (73.6) experienced headache. The most frequent tumor type was clinically nonfunctioning adenoma (50%), followed by prolactin-secreting adenoma (34.1%), growth hormone-secreting adenoma (13.2%) and last adrenocorticotropin-secreting adenoma (7.7%). there were 86 macro adenomas (94.5%) and in 13 patients (14.3%) the tumor invaded cavernous sinus. mean height was 33.05 mm, length was 26.58mm and width was 29.71mm. Conclusions: Clinical manifestations of pituitary adenomas are the result of excess hormone secretion (acromegaly, hyperprolactinemia, hypercortisolism...) and to compression of the surrounding structures (headache, visual disturbance and ocular movement palsy). The endocrine examinations are very important for diagnosis and treatment. MRI is the first choice.

In the period of 1999-2003, a double blind trial was performed with 140 patients selected randomly divided into 4 groups, authors predicted TCD4+ count of HIV infected persons from the results of skin test using dinitrochlorofenyne (DNCB). The slope of the regression line was greater significantly than zero, indicated that TCD4+ count decreases as the skin reaction to DNCB decreases (slope = 11.37, 95%Cl = 9.82 to 12.91, p=0.005, Y = 166.06 + 11.37X, r2 = 0.61).

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
