Observations were based on examination of 54 operators who have worked for 5-20 years in telecom cars. Authors concluded that the changes in electrocardiographic indicators are still within the physiologic limits.

A patient with the chronic myeloid leukemia received the autologous stem cells transplantation of peripheral blood. The results have shown that the patient was responded well with the autograft, the graft grew early as estimation. The patient also responded completely with the treatment by Hydrea. The clinical and hematological signs were stable in the long-term. The complication during transplantation was mild. The total survival duration was 75 months.

88 patients with the chronic myeloid leukemia treated with Hydrea during 1/1999 - 12/2000. Most of them admitted to the center for hematology and blood transfusion in the conditions of very high leukocytosis and acute mortality risk due to cerebrovascular obstruction. Patients indicated by high dose of Hydrea in average duration of treatment of 6.5 (1.8 days. The treatment with Hydrea demonstrated that the survival duration of patients was lasted. The drug had fewer side effects. The treatment was not expensive. This is suitable for economic conditions of patients in Vietnam.

200 patients aged 18-67 including 109 males, 91 females were diagnosed definitely as lumbar disk prolapsas by saccoradiculography and treated surgically in the Hospital N0103 from Nov 1999 to Nov 2003. Saccoradiculography give accurate results, without complication and consistent with post operative diagnosis. The tecnique can be used at provincial level, in lacking of MRI

71 patients with severe burns, who had had various organ dysfunction were divided randomly into 2 groups: one underwent continuous veno-venous hemofiltration (CVVH), and the other was control group. Results showed a significant decrease of plasma level of cytokine, including IL2, IL6, IL8 and TNF after CVVH (p<0.01). In addition, mortality rate of CVVH group accounted for 38.71%, considerably lower than those of the control group

A study on 125 patients, who were operated on lumbar spinal disk herniation, included 67 men and 58 women, from 18-70 years old. These patients were divided into 2 groups: group 1 was given epidural anesthesia: 34 men and 32 women used bupivacaine 1mg/kg –1, fentanyl 1µg/kg-1, adrenaline 1/2000.000 with a volume of desensitizer was 1.5 – 1.6ml/spinal cord unit. Fentanyl was mixed into drug injected in extra dura mater. Group 2 was given subarachnoid anesthesia: 33 men and 26 women used bupivacaine 0.15mg/kg –1, fentanyl 1µg/kg-1. Respiration indexes had been measured before and after anesthesia 30 minutes. Results: 30 minutes after anesthesia, group 2 had a decrease of the respiration indexes such as VC, VC%, FEV1, and Tiffeneau, compared that before anesthesia (p<0.05). In the group 1, the respiration indexes reduced not significantly with p> 0.05. Subarachnoid anesthesia had Tiffeneau and VC% were lower than epidural anesthesia (p<0.05). The respiration indexes of subarachnoid anesthesia group decreased but still in the allowance limitation.

Background: Leg bone fracture is common seen in orthopedic trauma. Currently, the trend of treatment is using a less invasive technique. Especially, with application of C-Arm in surgery, closed Kuntscher nailing technique has made the treatment of leg bone fractures achieving more new improvements. Objectives: To summarize the experiences in the technical implementation process and to assess results of treatment. Subjects and method: A descriptive, retrospective study was conducted on 112 patients was confirmed diagnosed with leg bone fractures (81 males, 31 females, the average aged 29\xb15.3), were operated in Da Nang General Hospital from January, 2004 to June, 2006. All of them were performed with Kuntscher intramedullary nail in tibia without opening fracture cavity, in condition of without C-Arm. Results: The patients with combined injuries included 5 cases of 2 legs fracture, 2 cases of hip fracture, 5 cases of leg fracture in 2 stages, 1 case of collabone fracture. Postoperative observations: no case of infection, patients were discharged after 2-7 days, the average length of hospitalization was 3\xb12.4 days. Complication: 1 case of secondary deviation, no case of any delay to heal bone, broken nails. Recording a case of nail was rise up to cause painfully and synovial capsule inflammation of knee joint. Conclusion: The implementation of this less invasive technique should be orderly done. The most ideal indication was tibial shaft fractures in stage of middle 1/3. Because of a minimally invasive technique so patients were less painful, fracture healing quickly, early mobilization could be set, surrounding joints were not affected.

Effect of marcaine plus fentanyl combination for lumbar epidural anesthesia was investigated in random series of 33 patients who were undergoing lumbar discectomy. Patients received 1mg/kg marcaine with 1mcg/kg fentanyl. The volume of local anesthetic solution was calculated basing on the number of segments that needed to block: 1.5 - 1.6ml per segment. It was found that the marcaine plus fentanyl combination provided high effect (100%) on epidural anesthesia, rapid onset (7.51.8 min), long working duration (33070 min), caused milder hemodynamic changes, decreased the incidence of adverse events and produced satisfactory operating condition.

A prospective study involved 64 patients (43 men, 21 women) aged from 20 to 62 years with lumbar disc herniation who had operated at Military Hospital 103. These patients were divided into 2 groups. Group 1 received marcaine (0.25%-0.375%) plus fentanyl, group 2 received marcaine (0.35% - 0.5%) alone for lumbar epidural anesthesia. The volume of local anesthetic solutions injected epidurally was calculated based on number of segments that had to block, with dose of 1.5 - 1.6 ml per segment. The results showed that compare with marcaine alone, the combination of marcaine and fentanyl provided better analgesic effect, faster onset and longer duration of action, caused milder hemodynamic changes, decreased the incidence of adverse effects and produced satisfactory post-operative condition

This study is aimed to investigate the activity of lymphocytes of recurrent spontaneous aborters, their response to phytohemagglutinin (PHA) mitogen was studied by comparing with that of normal pregnancy and normal non-pregnancy women. The results are as follows: there is no or a significant decrease of suppression of lymphoblast transformation in recurrent spontaneous abortion comparing to that of normal pregnancy women. It should be considered all of three parameters: absolute counts of OD with PHA, non-PHA and stimulation index as a general analysis for lymphoblast transformation.
