Fifty three of normogravid - normotensive women who subsequently developed pregnancy - included hypertension demonstrated an increase in diastolic blood pressure at least 20 mmHg when turned from the lateral recumbent to the supine position, between twenty eight and thirty six weeks of gestation. Conversely 95.8% percent of women who did not demonstrate such a rise in diastolic blood pressure when turned to supine position did not become hypertensive during that pregnancy. The results demonstrated the high validity of this method as follow: the sensivity of predictive value: 65%. The specificity of predictive value: 93%, the positive predictive value: 53%, the negative predictive value: 96%.

Ecstasy has been registered in 1914 as an anti-tired medicament for military use. From the year 1980, Ecstasy becomes an excitant using in amusing with the name of “shaking drug”, “Rabid drug”.

Antibiotic use must carefully and must exactly consider according to indication and combined exactly method and disease. To against antibiotic resistance, urgent methods is needed such as drugs used exactly disease, sufficient dose and enough time. For physicians, should careful if prescribe antibiotic, don't use new drug if older drug still effective, review antibiotic resistance to choose exactly, preservation obey exact standards, limited using antibiotic for cattle and poultry

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

Center for the trauma and orthopady treated 200 cases of foot deformity in which 1,500 cases received operations. Most of them were congenital club foot (70%) followed by club food due to the polio fever(20%) due to the brain paralysis (5%) and due to arthrogrip ossis (5%). The orthopadic equipments were applied for 35 cases. The equipment was used within 5 weeks and continuously fixed by gypsum up to 3 months from the day of operation.

Nosocomial pneumonia is associated with increases in health care costs, morbidity and mortality. Data from our study in Bach Mai Hospital in 90 patients admitted to intensive care units from 1999 to 2001 indicate that, approximately 86% of patients got nosocomial infections. Gram(-) organisms were predominant (76%) with P.aeruginosa 57.3%; S.aureus 10.7%; Enterobacter 7.7%; Acinetobacter 6.8%. Almost these gram(-) becterial isolates were sensitive to imipenem (95.7%) and amikacin (87.8%).

3 types the results were evaluated according to the efficacy of obtained vaccines have shown that the mininal infective dosages of poliovirus in production of oral live poliovirus vaccine in the renal cells of monkey which given the highest efficacy were 103 TCID 50 /bottle of Roux, 104TCID/bottle of Roux and 103 TCID/ bottle of Roux for type I (strain: WHO-IS-C), type II (strain: IIS-90A) and type III (IIIs-79A), respectively

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.

Two positive clones inserted DNA fragment of HBV coded for intracellular HBsAg synthesis from 2 strains of P.pastoris: GS115-47-4 (Mut+ His 4) and KM71-47-1 (Muts; His4 arg4 aox1: ARG4) were selected for developing a DNA recombinant hepatitis B vaccine in laboratory scale. Different types of growth media and expression media were used for the study on HBsAg expression levels from those two clones. The highest level of HBsAg - 1318mcg/l with MGYH/MMH medium after 96h and 2220 mcg/l with BMGY/BMMY medium after 72h of induction was obtained in clone GS115-47-4 and 241 mcg/l after 48h and 1680 mcg/l after 48h in clone KM71-47-1 observed were respectively.
