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

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

Studying of 15 patients with tuberculous ureteric stricture treated by extraversical ureteral reimplantation (4 males and 11 females, 10 cases of unilateral ureteric stricture and 5 cases of bilateral ureteric stricture). The mean operation time: 101.6 minutes, mean estimated blood loss: 68.6ml, mean time of removal of urethral catheter: 7 days, mean postoperative hospitalization: 8.13 days. Postoperative complications were minimum: 1 case of mild infection because oh ureteral stent migration, 1 case of moderate intraversical bleeding... Long-term outcomes of operation were satisfactory: on 12 patients performed follow-up UIV, 8 with good amelioration and 3 with pretty good amelioration, 1 without amelioration, mean follow-up duration: 15.5 months

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

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)

At Hospital No175 from 1998 to 2001, the study was conducted on 152 subjects (78 female, 74 male), no statistically significant difference of age, divided into various groups: group of due to stone (40 subjects), group of AIGB combining with stenosis of MBD (42 subjects). Two control group comprise of IGB due to stone (36 subjects), group of stenosis of MBD due to stone (34 subjects). In AIGB the dimention of gall bladder (+B) was not enlarged. The variation of this dimention relates to the severity of stenosis of MBD or the shrinkage of the GB. Murphy sign varies according to the severity of stenosis. The signs in internal wall of GB is the main symptoms reflecting the variation of the wall and the condition in GB. Acute damage of the wall of GB does not change sigificantly the ultrasonic sign of chronic inflammation in the wall of GB. For strenthening the accurary of the diagnosis it must not any sign note solitarily but it has to combine 2-3 signs

60 patients with chronic B hepatitis were treated at The Hospital No 108, using At Can Ninh, a preparation of traditional medicine. Some clinical symptoms were improved rapidly such as themia anotexia, jaundive, clark yellow urine. In comparing with control subjects, after 2-3 weeks treatment, SGOT, SGPT in blood were reduced more quickly. The preparation also reduce it Bs Ag, HBV- DNA level and serum converting rate was higher 14,3% verous 0% with p<0,05 after 3 months treatment. Some uncomfortable manifestation such as pylori pain and nausea in 2/30 patients were disappeared immediately after the cease of medicine.

At the Military Hospital No108, from August 2000 to May 2002, 111 patients with respiratory tract disease were studied perspectively. Results showed that the most vulnerable age 1-5 years old (26.13%), 5-10 years old (41.44%). 26 cases were infected with streptococci (23.42%). Among respiratory tract infectious patient streptococci A 26% were isolated, cartaphalis 18%. Among bronchitis patients, Streptococci A 14%, M cartahalis 12%. Among rhumatism arthritis patients Streptococci alpha 12%, cartahalis 6%
