  2. Ion objective : to investigate effect of nd : yag laser irradiating root canals on periapical tissue. methods : three minipigs were used in this study, deciduous premolars were opened, pulps were extracted, root canals were enlarged, then irradiated with nd : yag laser 30s and filled conventionally. the changes of periapical tissue were observed after 1, 3, 7 and 15 days. results : after one day, periapical tissue showed enlargement and engorgement of blood vessel and a few of leukocyte, the changes were more serious than in control. after 3 and 7 days, there were minor reactions in periapical tissue and same as the control group. after 15 days, periapical membrance in most specimens was normal. slight inflammatory reaction was found in the test group as same as in control group. conclusion : there was little damage to periapical tissue with the laser irradiation

    目的:觀察激光在根管內照射后對根尖周組織的作用.方法:選3隻小型豬，全麻下將乳前磨牙開髓、抽髓，根管擴大后，激光照射30秒，做常規根管充填.對照組為常規根管充填. 1天、 3天、 7天和15天後觀察根尖周組織的變化.結果:激光照射后1天，根周膜血管充血、輕度炎癥，對照組只有根尖周膜充血.激光組組織反應比對照組稍重.激光照射后3天和7天，少數病例根周組織有輕度的刺激與對照組的病理表現相近.激光照射后15天部分標本根周膜正常，部分標本有輕度炎癥反應，與對照組結果基本相似.結論:本激光照射條件對根尖周組織沒有明顯損傷作用，可供臨床應用時參考
  3. The damage of wheat seedlings induced by enhanced uv - b radiation in physiology can be repaired partly by he - ne laser irradiation with enzymatic and non - enzymatic system including of decreasing the mda concentration, increasing the contents of asa, gsh, uv - b absorbing compound, and the activities of sod, cat, pod

    He - ne激光輻照可使uv - b輻射后小麥幼苗mda的含量明顯減少； asa 、 gsh含量明顯增加； sod 、 cat 、 pod等酶活性增加。說明he - ne激光可通過酶促與非酶促抗氧化系統，增加小麥幼苗在生理水平對輻射損傷的修復能力。
  4. The whole - body gamma knife system is a kind of non - invasive medical instrument by using co - 60 as the gamma ray source. according to geometrically focusing theory, the gamma knife system can precisely focus in spirals 30 beams of gamma rays from different directions to a target through a collimator. by the collimator s direction, the predetermined lesion will be under radiation in heavy dose and subsequently be destroyed completely

    體部伽瑪刀是利用能產生伽瑪射線的鈷60作為放射源，根據幾何聚焦原理，將30束伽瑪射線從不同方向和位置通過準直后經一個固定的軸旋轉聚焦到焦點，形成品質優良的劑量區，將腫瘤組織置於該高劑量區中，即可在預定時間內將病變組織摧毀，體表和焦點以外的正常組織僅受到瞬時照射而基本上不受損傷。
  5. After several decades " improvement in technology and accumulated experience in clinical use, more and more intracranial tumors have been treated with this unit, but the detailed mechanisms are not understood about its neuroradiobiological effects, especially the early or acute damage and time - dependent changes of neural cells in the target and surrounding brain regions

    經過幾十年的臨床經驗的積累和技術的改進，放射治療已經成為顱腦腫瘤的重要治療手段之一。但迄今對于電離輻射神經放射生物學的基礎研究尚不足，尤其對于照射后靶區及其周圍組織早期或急性期的損傷程度及時程變化缺乏系統的動物實驗研究，本實驗目的即在於此。
  6. Only a few patients, especially those who have received large dosage of radiation at a time, may have some side effects, such as, headache, naupathia, vomit, fever and so on. it is mostly caused by damage of capillary vessel, edema or infection due to radiation. however, the side effects just lasts a short period of time and they can disappear more quickly with the assistant of medicines such as dehydrator

    少數病人特別是接受單次較大劑量照射的病人可能會出現一些副反應，如照射后幾天內出現輕度頭痛惡心嘔吐發燒等，這多半是由照射引起的毛細血管損傷水腫和炎性反應，時間短暫，一般都可自行恢復正常，適當用一些藥物如脫水劑等治療，效果更佳。
