A study aimed to evaluate the antioxidant activity (AOA) of traditional medication by determining the iodine index of Tween 80 in tentative samples (with the extraction of traditional medication) and control samples (without the extraction of traditional medication). It should not apply the spectrometry to evaluate the AOA of these medication because of their complicated chemical components, especially chromatic compounds which interfere the photic density

66 flaps including 6 controlled, were divided into two models, each includes 30 flaps and each model was divided into 5 groups, evaluated after 4, 8, 12, 16 and 20 days after implantation. From the random implantation of a isolated pedicle of artery or vena in an abdomen skin flap, new blood vessels occurred and connected with the existent system of vessels in the flap. After 20 days, new vascularity was established in both models, as the same in the control group. Blood supply was considered appropriate and the flap could be moved safely along the newly implanted pedicle

68 patients with stroke treated at Hue Central Hospital from March to June 2004. Risk factors as hypertension, smoking were evaluated. Patients had clinical and paraclinical examination such as CT scanning of cerebral skull, blood formula. Blood level of homocystein was estimated: The prevalence of stroke in gender male/female was 1.64/1 with 61.76% men and 38.24 women. Hypertension 85.24%, men/women 1.64/1. Smoke 67.65%. Blood level of homocystein increases in stroke by the rate of 77.94%, as for hemorrhagic stroke was 65.63%, for ischemic stroke was 88.57%. Stroke rate increased by age, especially after 55 years old. A positive correlation between blood level of homocystein and hematocrite was notified

Presention of 2 cases of bilateral urinary lithiasis treated totally by minimally invasive surgey: percutaneous nephrolithotomy, ureteroscopy and retroperitoneal laparoscopic surgery. If well equipped, almost all cases of urolithiasis could be treated by minimally invasive surgery

The concentration of blood homocystein (Hcy) in 26 patients with cerebrovascular accident (CVA) was determined preliminarily in Central Hospital in Hue city. 57.69% was the incidence of CVA in male and 42.31% in female patients (in male it was 1.36 fold higher than in female). Hcy concentration increased in 80.77% CVA patient. The rate of increase of blood level of Hcy was 66.67% in brain hemorrhage, 92.86% in brain infarctus. The incidence of CVA enhanced with the age, especially after the age of 55. High blood pressure accounted for 76.92% in CVA. 17/26 (65.38%) was the ratio of tobacco smoler.

There were some advantages of laparoscopic surgery: decrease of hospitalized time, relief of postoperative pain, high aestheticism, less effect to immune responses in body, decrease of recovery time of patients. Laparoscopic surgery has remained several disadvantages of surgical manipulations for surgeons. Robot is a vehicle that helps laparoscopic surgeons overcome this restriction. Robot-assisted laparoscopic surgery has strong points: providing 3D vision, increasing clever and complex level of surgical manipulations, minimizing vibration amplitude of tools, implementation in limited space. Weak points included losing of feeling when touch to surgical tissue, high cost equipment and surgery. Robot-assisted laparoscopic surgery is applied in gynaecological surgeries, urinary surgeries, heart surgeries, general surgery (cholecystectomy, Nissen procedures, etc)

From March 2000 to October 2001, 26 cancer patients of the cardiac region were registered to our study. Most patients were in advanced stage, apparently showed an impaired immunity both local and systemic. 20/21 (95%) cases of positive mutant P53 protein were detected at the tumor. Post operative adjuvant therapy with Aslem tend to increase the survival rate after resection (60.61% of the treated group compared with 33.33% of the untreated group)

Basing on statistics of head trauma during the period 1991-1996, the authors stress on the increasing number of patients from year to year. They put on remarks about the organisation of head trauma emergency, which is an acute problem to be solved.

From November 1999 to November 2000, we observed the preoperative uroflows of all patients with prostatic neoplasm diseases. There were 94 patients (mean age 70.5(8.08) who had indications for TURP. The Qmax was 7.67(mL/s; voided volume was 261.8(142.4mL. The patterns of uroflow consisted 0f 64% obstructed, 14% intermittent, 19% interrupted and 3% normal. We noticed that 93.6% of all patients with symptoms of bladder outlet obstructions involved in our research had abnormal uroflows. We also had to consider the relationship of automatic and visual interpretations of uroflowmeters results. In patients with voided volume under 150mL, Bristol monogram is a very useful tool for correcting Qmax.
