The result of dissolution test of sulfamethoxazole and trimethoprim from 6 investigating tablet samples demonstrates that the dissolution rate of substances is very various. It means that the dissolution of water slightly soluble substances from solid dosage forms is influenced by the formula and the technique of preparation

An investigation was conducted on 101 cases of biliary calculus. Results show a rate of 17.82% of bile duct ascariasis, from them 75% with ascaris found in the large duct and 75% died. 33% of cases had experienced a previous history of bile duct ascariasis. Bile culture had indicated a positive rate of 81.25% of aerobic bacteria and 4/6 of anaerobic.

There have more than toxic microbial and viruses in the list of bioweapon for the bioterrorism and biowar. The fights for bioterrorism and biodisaster are activities of society and community. Individuals and community have responsibilities to protect, fight, and reduce the damage timely and effectively to bioterrorism. The professional facilities are responsible for investigating, isolating the germs, toxics and implementing the effective solutions for management of outcomes of bioweapon.

Authors reviewed all patients who received blood ad blood components during hospitalization and found that: The total number of patients received blood is 7073. The total blood (WB, RBC, plasma) use is 24041 units, approximate 5838L with medium number: 1944L per years, 612L per month, 3 units per 1 patient, especially in emergency operation: >30%. The blood components transfusion application is limited: RBC: 3524 units (14%), FFP: 3248 units (13%), mean while whole blood use rate is high: > 71%. Hematology and blood transfusion department in Viet Duc Hospital has been producing successfully blood components (Red Blood Cells, Fresh Frozen Plasma, Platelets concentrate, Cryoprecipitated...) for clinical use.

The application of H4 cream for treatment of 20 experimental traumatic wounds on rabbits has obtained some satisfactory results as follows: Reducing the inflammatory process, decreasing the quantity of bacteria on the wound’s surface and quantity of neutrophil in injury’s tissue. Accelerating the healing process including early debridement, proliferation of fibroblast and neo-angiovascular, promoting the granulation tissue, re-epithelialization and cicatrization and no side-effects.

Telemedicine is a term of the remote health care, developed in the developed countries to apply the information technology in delivering the health services to remote areas promptly and effectively. There were 2 major trends of development of telemedicine. The firstly, organization of network and transmission way in which the health and medical database such as texts, sound, image…were processed and searched through the local area network (LAN), wide area network (WAN), Intranet and Internet. The secondly, development of software for database management such as hospital information system (HIS), system of back up, process and exploitation of database for remote diagnosis and treatment (telediagnose) picture archiving and communication system (PACS), Digital imaging and communications in medicine (DICOM). The telemedicine has been developing in the some countries of Asia such as Japan. The China considered particularly in the telemedicine with trend of using the health services by low technology.

79 serum samples of tetanus patients admitted to The Institute for research on Clinical Medicine and Tropical Diseases from November 1996 to May 1997 were analysed by technique of inoculation in mice. The results showed that: 1) Free circulating tetanus toxin was detected in 19% of cases with 5.1% of cases with 5.1% of cases of low toxin concentration and 13.9% of cases of high toxin concentration. All them are negative after 5 days of ATS injection (Anti Tetanus Serum) with 6000-9000 IU (M.I). 2) The presence of free circulating tetanus toxin in the blood was not related to infectious condition of the wound (P>0.05). 3) Mortality in the group with positive free tetanus toxin (60%) are higher significantly (p<0.01) than the negative one (20.3%). So, free circulating tetanus toxin in the blood had a severe prognostic value in tetanus patients. 4) Using ATS was necessary for the treatment of tetanus patients. 5) Serum antitoxin concentration in most of tetanus patients (90%) was lower than the 'protective level' (<0.01IU/ml).
