Since the 1930s, there have been more than 20 monographs and 550 research papers on the study of the history of Goryeo Dynasty in Chinese academia. The study involves many aspects such as diplomacy, politics, society, economy, development, ideology, culture, human ties, and compilation of history materials and so on. So far some progress of the study on the history of Goryeo Dynasty has been made in the fields mentioned above, but more inspiration should be involved for a better further study. First, the future study should widen research perspective,with breaking through tradition of research on the history of relations and attaching importance of “subject narration and subject consciousness” of research object, the Goryeo Dynasty, itself. In addition, more historical materials should be included in a systematic and detailed study to increase the refinement and depth of the discussion topic. Last, more frequent academic exchanges are of great significance to expand the international perspectives of the study.

家兎 心博에 미치는 迷走神經幹 電氣刺戟核果에 關하여

李廷淸,徐文錫 전북대학교 의과학연구소 1980 全北醫大論文集 Vol.4 No.1

In this study, effect of electrical stimulation to the afferent vagal nerve on the cardiac rate was investigated in the rabbit. Electrical stimulation of 10 Heltz of frequency, 10 volt of intensity and 0.5 msec of pulse duration to the afferent vagal nerve caused decrease in the cardiac rate, while that of 80 Heltz increase the rate. There was no noticeable difference between the cardiac reponses by stimulation of the left vegal nerve and the right vagal nerve. Vagotomy, intravenous atropine or intraventricular atropine inhibited bradycardia by low frequency of stimulation, and tachycardia by high frequency of stimulation was inhibited by intravenous Inderal or intraventricular regitine. From the above results, it is suggested that central cholinergic and adrenergic mechanism as well as peripheral autonomic nervous system are involved in the change of heart rate to electrical stimulation of the afferent vagal nerve of the rabbit.

脊髓內 有鉤囊충症 1例報告 : Case Report

李廷淸 中央醫學社 1976 中央醫學 Vol.30 No.6

A rare case of intramedullary cysticercosis in a 36 year old male is presented. The patient had a marked paraparesis with TIO sensory level, absent deep tendon reflexes and sphincteric disturbance. Thoracic myelography showed a complete block of dye column a. T10spinal level and it proved at laminectomy to be due to a solitary cysticercus vesicle. Intramedullary cysticercus vesicle was removed from the region of the central canal through posterior myelotomy. The patient recovered slightly from his neurological dysfunctions but aspastic paraparesis was remained slightly. The author report a case of intramedullary cysticercosis located in lower thoracic cord and review previously reported cases.

뇌내(腦內) Norepinephrine, Clonldine에 의한 심박(心搏) 및 혈압변동(血壓變動)에 관한 연구(硏究)

이정청(Jung Chung Lee) 대한약리학회 1978 대한약리학잡지 Vol.14 No.1

1) Urethane 마취가토(痲醉家兎)의 내뇌(腦內)(측뇌실(刻腦室) 또는 소뇌연수조내(小腦延髓槽內)에 norepinephrine (NE), clonidine을 주입(注入)할 때 일어나는 심박감소(心搏減少), 혈압하강(血壓下降)에 관한 이들 약물(藥物)의 작용점(作用點)을 조사(調査)할 것을 시도(試圖)하였다. 2) NE의 뇌내주입(腦內注入)은 심박감소(心搏減少)를 일으켰으나 혈압(血壓)에 미치는 영향(影響)은 뚜렷치 않았다. Clonidine은 심박감소(心搏減少), 혈압하강(血壓下降)을 일으켰다. 3) 측뇌실내주입(刻腦室內注入) 소뇌연수조내주입간(小腦延髓槽內注入間)에는 NE, clonidine, phenylephrine, isoproterenol의 심박(心搏), 혈압효과(血壓效果)에 차이(差異)가 없었다. 또 NE에 의한 심박감소효과(心搏減少效果)의 출현(出現)은 소뇌연수조내주입시(小腦延髓槽內注入時) 더 빨랐다. 4) 약(約) 2시간(時間) 간격(間隔)으로 NE를 반복(反復) 주입(注入)할 때 심박효과(心搏效果)에는 거의 변동(變動)이 없었으나 혈압효과(血壓效果)는 반복주입(反復注入)함에 따라 혈압상승효과(血壓上昇效果)가 현저(顯著)히 나타났다. Clonidine의 심박감소(心搏減少) 및 혈압하강효과(血壓下降效果)는 반복주입(反復注入)에 따라 점차 약화(弱化)되었다. 5) NE 주입후(注入後) NE 효과(效果)가 지속(持續)하고 있을 때 clonidine은 더 이상(以上)의 심박감소(心搏減少)를 일으키지 않고, 혈압하강(血壓下降)도 일으키지 않았다. Clonidine 주입후(注入後) clonidine 효과(效果)가 지속(持續)하고 있을 때 NE는 더 이상(以上)의 심박감소(心搏減少)를 일으키지 않았고 현저(顯著)한 혈압상승(血壓上昇)을 일으켰다. 6) Regitine 또는 desmethylimipramine의 뇌내주입후(腦內注入後) NE는 심박(心搏)에 거의 변동(變動)을 일으키지 않았으나 현저(顯著)한 혈압상승(血壓上昇)을 일으켰다. Clonidine은 심박(心搏), 혈압(血壓)에 거의 변동(變動)을 일으키지 않았다. 7) Reserpine 처리가토(處理家兎)에서는 NE는 심박증가(心搏增加)와 혈압상승(血壓上昇)을 일으켰으며, clonidine은 심박(心搏)에는 거의 변동(變動)을 일으키지 않았고 경미(輕微)한 혈압상승(血壓上昇)을 일으켰다. 8) NE 및 clonidine에 의한 심박감소(心搏減少), clonidine에 의한 혈압하강(血壓下降)은 주(主)로 presynaptic α-adrenoceptor를 중개(仲介)하여 일어나나, NE 및 clonidine에 의한 혈압상승(血壓上昇)은 presynaptic site 이외(以外)의 부위(部位)를 중개(仲介)하여 일어나는것 같다. 1) It was attempted to clarify the sites of action of central (either intraventricular or intracisternal) norepinephrine(NE) and clonidine to cause cardiac slowing and hypotension in urethane-anesthetized rabbits. 2) NE produced cardiac slowing but indistinct effect on blood pressure. Clonidine produced cardiac slowing and hypotension. 3) Intraventricular and intracisternal administration of NE, clonidine, phenylephrine and isoproterenol did not make difference in their effects, except that the onset of cardiac slowing by intracisternal NE was more rapid than intraventricular NE. 4) Upon repeated administration of NE at the intervals of about two hours, blood pressure responses changed to the pressor ones, the cardiac slowing unchanged. By this procedure the cardiac slowing as well as the hypotension by clonidine were gradually diminished. 5) Clonidine, when given during the NE effects were persisting, did not produce the lowering of blood pressure and further decrease of heart rate. NE, when given during the clonidine effects were persisting, produced marked elevation of blood pressure but did not produce further decrease of heart rate. 6) After intraventricular administration of regitine or desmethylimipramine, the cardiac slowing effect of NE and the clonidine effects were not observed, whereas NE produced marked elevation of blood pressure. 7) Reserpinized rabbits showed pressor and cardiac accelerating responses to NE; slight pressor, and little cardiac responses to clonidine. 8) It seems that the cardiac slowing by both clonidine and NE as well as the hypotetsion by clonidine are mediated by the presynaptic α-adrenoceptor in the brain but the pressor responses to NE and clonidine are mediated by other site(s) than the presynaptic ones. 1) It was attempted to clarify the sites of action of central (either intraventricular or intracisternal) norepinephrine(NE) and clonidine to cause cardiac slowing and hypotension in urethane-anesthetized rabbits. 2) NE produced cardiac slowing but indistinct effect on blood pressure.

방인석,이정청 전북대학교 의과학연구소 1983 全北醫大論文集 Vol.7 No.1

Trigeminal neurinoma located only in the cerebello-pontine angle is rarely encountered and it usually accompanies cerebellar signs. Trigeminal neurinoma is commonly arised from the Gasserian ganglion and located in the middle cranial fossa or extended into the posterior cranial fossa as dumbbell shape. A rare case of trigeminal neurinoma located only in the right cerebello-pontine angle without any evidences of cerebellar signs is presented. The patient was 65 year-old man who had trigeminal neuralgia on the right mandibular area. The tumor arised from the sheath of the right trigeminal nerve root of the cerebellopontine angle. It was successfully removed without injury to the nerve itself under the surgical microscope.

요추간판탈출증의 수술적 치료성적

조재우,이정청,김재은 대한신경외과학회 1994 Journal of Korean neurosurgical society Vol.23 No.7

저자는 1980년 1월부터 1991년 12월까지 약 12년간 전북대학교 병원 신경외과에서 요추간판탈출증으로 수술을 받았던 환자중 추적조사가 가능했던 818예를 조사하여 보았던 바 다음과 같은 결과를 얻었다. 1) 수술 합병증으로 수술상처부위의 피부봉합지연이 있었던 예가 36예 였으며, 경막외 혈종이 2예, 간판염이 2예, 체액저류가 2예 였으나 위중한 합병증인 복강내 혈관손상이나 신경근 손상은 없었다. 2) 16예에서 1개월 이내 증상이 재발하거나 지속되어 재수술을 시행하였으며 7예에서 탈출된 간판핵 제거가 불충분하였고, 그외 경막외 혈종 2예, 간판염 2예, 체액 저류 2예, 불충분한 facetectomy 1예, 골극의 제거가 안되었던 예가 1예 였으나, 재수술로 전부 호전되어 좋은 결과를 얻었으나 hemodynamic change로 사료되었던 1예에서는 좋지 못한 예후를 보였다. 3) 25예에서는 6개월 이후 증상이 다시 발생되어 재수술을 시행하였는데 완전히 제거되지 못한 간판핵이 다시 탈출된 예가 14예로 가장 많았고 예후는 좋았으며 facet의 비후와 새로운 골극이 형성되었던 예가 각각 1예였으나 역시 예후는 좋았다. 그러나 심한 신경근 유착과 육아조직이 생성되었던 9예중 8예는 좋지 못한 예후를 보였다. 4) 818예의 요추간판탈출증 수술후 781예(95.5%)에서 좋은 결과를 얻었으나 4.5%에서는 좋지 못한 결과를 얻었다. 이상의 결과로 요추간판탈출증 환자에서 수술방법 및 수기와 환자의 선택이 중요하다고 사료되었으며 신경근 유착과 육아 조직의 생성을 억제하기 위한 방법이 강구되어야 할 것으로 사료되었다. The surgical outcome for lumbar discectomy has improved with development of surgical techniques and strict selection of patients. The authors could follow up and analyse 818 cases who underwent surgery due to herniated lumbar disc from Jan. 1980 to Dec. 1991 at Chonbuk National University Hospital. The early operative complications were delayed wound healing(% cases), extradural hematoma(2 cases), discitid2 cases), but there was no injury to nerve root and abdominal vessels. The specially designed paravertebral m d e retractor and nerve root retractor wwe useful in reducing the operative complications Sixteen patients were reoperated due to acute recurrent symptoms(Within one month). More than one-third of these(7/16) were due to missed disc material, and all of them had good results after reoperation. Twenty five patients were reoperated due to late recurrent symptomdmore than 6 months later). In almost two-third of them(l4/25), rerupture of remained disc material was found Reoperation of these cases had a good result as well. Epidural fibrosis and severe adhesion of nerve mot were showed for reoperation in 9 of the 25 cases. These complications had a poor result except 1 case even after reoperation. The surgical outcome of 818 cases were classified Excellent 618 cases(82%), Good 110 cases(135%), Fair 29 cases(3596) and Poor 8 cases ( 1 % ) . Surgical technique and proper selection of patients were considered as important facter obtaining the better result.

The large suprasellar cerebral cysticercosis is presented. Twenty-two year old female patient was admitted to Chonbuk National University hospital because of headache and Lt. homonymous hemianopsia. The preoperative brain C-T revealed that the single large low density was located in the suprasellar area but not enhanced. It was confused as the congenital arachnoid cyst in brain C-T, but cysticercosis was confirmed by operative and biopsy findings. The patient discharged unevenfully without any neurological deficit.

극외측 요추간판 탈출증의 진단 및 수술적 치료

박철형,이정청,김근수 의과학연구소 1996 全北醫大論文集 Vol.20 No.1

Lumbar disc herniation into and beyond the neural foramen may present difficult diagnostic and therapeufic considerations for the neurosurgeon. Surgical intervention predicted primarily on the clinical picture may lead to exploration of the incorrect level, to incomplete exploration or tounnecessary addtional interspace exposure, any of which may produce the failed back syndrome. In far lateral lumbar disc herniation, the myelography usually shows negative findings and high resolution CT is best method of diagnostic modality. Sometimes it was confirmed only by the discographic CT. If these herniations are diagnosed, they often cannot be adequately exposed by the classic midline approach. A partial or complete unilateral facetectomy to expose these herniations can lead to vertebral instability or conteribute to continued postoperative back pain. The authours present 7 pateints diagnosed as having far lateral lumbar disc herniation from jan. 1994 to Dec. 1995. Main symptoms relating to far lateral LDH consist of severe radiationg leg pain, hypesthesia and aggravation of leg pain during lateral tilting of lumbar spine toward the lesion side. Straight raising test(SLRT) was negative in three cases. Two cases who were difficult to be diagnosed, with lumbar CT or MRI could be diagnosed with discographic CT. PHL with medial facetectomy was useful for foraminal type and paramedian approach for extraforaminal type. However, paramedian approach with PHL was useful for combined types of lesion. All the patents with far lateral LDH showed the satisfactory results : excellent in six, good in one.
