BACKGROUND: In hospital laboratory using Microscan, the search for an isolate or the analysis for antimicrobial susceptibility rates were obtained by the Data Management System (DMS) software. However, it is hard to convert DMS database to other file formats in addition to some limitation in using the database. We applied BacLink 2 and WHONET 5.1 softwares to convert and analyse DMS database for the utilization of the isolate profiles and the antimicrobial resistance rates. METHODS: Specimen and microbial data were printed as 'Short report form', an ASCII text file, from Microscan DMS. BacLink 2 software was used to convert the printed file to dBASE format file. Statistical analyses were performed using WHONET 5.1 software. RESULTS: Data of isolates were obtained as 'Short report form' in one month intervals. This file could be converted to other database file using BacLink 2 software. The antimicrobial resistant profiles were obtained, and the susceptibility, intermediate resistant, and resistant rates for each isolates could be analyzed. CONCLUSIONS: In this study, BacLink 2 and WHONET 5.1 software were successfully applied for the conversion of the database. Analysis of isolate profiles and antimicrobial resistant rates could be performed in other personal computer systems. The database management by BacLink 2 and WHONET 5.1 software could be applicable for the convenient statistical analysis in microbiology laboratories using Microscan.

We have a step backwards in comparing with the previous 40 years in the education and the organization of medical laboratory examination. While our equipment and techniques have got new great success and the needs have increased. Typically, in clinical briefing, laboratory doctors and technicians have been always absent, it seems that it is due to the leak of a deep knowledge and a large skill of laboratory. Therefore their roles were reduced. An improvement in the programm of formation of laboratory doctors and experts with various branches: biochemia, hematology, blood perfusion was recommend

Serum consists of water (93% of serum volume) and nonaqueous components, mainly lipids and proteins (7% of serum volume). Sodium is restricted to serum water. In states of hyperproteinemia or hyperlipidemia, there is an increased mass of the nonaqueous components of serum and a concomitant decrease in the proportion of serum composed of water. Thus, pseudohyponatremia results because the flame photometry method measures sodium concentration in whole plasma. A sodium-selective electrode gives the true, physiologically pertinent sodium concentration because it measures sodium activity in serum water. Whereas the serum sample is diluted in indirect potentiometry, the sample is not diluted in direct potentiometry. Because only direct reading gives an accurate concentration, we suspect that indirect potentiometry which many hospital laboratories are now using may mislead us to confusion in interpreting the serum sodium data. However, it seems that indirect potentiometry very rarely gives us discernibly low serum sodium levels in cases with hyperproteinemia and hyperlipidemia. As long as small margins of errors are kept in mind of clinicians when serum sodium is measured from the patients with hyperproteinemia or hyperlipidemia, the present methods for measuring sodium concentration in serum by indirect sodium-selective electrode potentiometry could be maintained in the clinical practice.

BACKGROUND: To prevent medically significant errors, hospital laboratories must perform thorough statistical quality control (QC) procedures. We surveyed the QC status of small laboratories and created new statistical QC software that they can easily use for improving QC. METHODS: A questionnaire on the status of external and internal QC was created and sent to clinics and hospitals with small-scale laboratories. We then created QC software that can be downloaded and installed for free. RESULTS: External quality assessments were performed in 32% of the clinics (22 of 66) and 52% of the hospitals (12 of 23). Seventy-three percent of all institutions (66 of 90) carried out an internal quality assessment based on their own guidelines, mostly using commercialized QC materials. However, only 52% of clinics and 23% of hospitals used their own acceptable range instead of the manufacturer's expected range. In addition, the proportion of manual QC management reached 52% in clinics and 82% in hospitals. The QC software we designed covers all the basic functions of statistical QC and aims to improve the quality of laboratories. CONCLUSIONS: We obtained basic data on the current status of external and internal QC in small-scale laboratories using this survey. Furthermore, we suggested that new QC software may actually help to improve QC of small laboratories.

The Biomedical Laboratory Center of Hanoi Medical University was established in January 17th 1997 and comprises 4 small labors: the functional tests; biochemical; immunology and genetic. According to its functions and tasks, the labor has human resources with the high technical and scientific levels. This resource originated from the faculties of Hanoi Medical University. This is an activity pattern which is suitable and convenient for staffs and students in the university.

The survey covered 11 cities/provinces with 179 servey copies distributed to staffs involved in microbiological testing during 2003-2004. Results showed that tested microbiological samples of water and food were 790±817 and 699± 552 (x±SD)/year, respectively, with 4-5 testing indicators applying for MPN7-9 tubes. The number of samples for testing microorganism in the environment was still limited. In five years of 2000-2004, epidemics occurred in some provinces like typhoid, cholera and dengue fever. Those were tested for causes making up 88% and the rate of success was high. Some causes for epidemics (typhoid, cholera, dengue fever and pacillary dysentery) can be identified at provincial centres of preventive health.

Clinical and laboratory findings was investigated on 46 patients who had diagnosis of lupus glomerulonephritis type IV. The obtained results showed that clinical features are severe with 45.7% patients had hypertension, 34.8% patients had acute nephritis syndrome and 56.5% had nephrotic syndrome. Especially, there were 95.7% patients have renal insufficiency. Among them, 26.1% had a severe renal failure (blood creatinine level >300mmol/I). But after 1 month of treatment, 100% of renal insufficiency patients have blood creatinine level < 300mmol/l and 72.8% of renal failure patients who had creatinine level > 300mmol/l had improvement in renal function

Vnukovo-32 a cell culture rabies is used to study the vaccine strain technology of inactivated culture rabies vaccine production in primary hamster kidney cells. The master and working seeds meet the criteria of rabies vaccine strain titer (5.5 log LD 50 - 7.1 log LD 50/ml) according to WHO standard. During the study, we have used the procedure for inactivated, non concentrated rabies vaccine production of Russia and other countries procedures as references. The result was we constructed the procedure for inactivated, concentrated cell culture rabies vaccine production at laboratory scale.
