Thirty two cases of the cervical spinal injury have been collected except those which associated with the injury on the other sites, such as head or internal organs. Nine cases of them were managed with surgery by anterior and/or posterior approaches The others were only immobilized by traction. Independent of operative method, we acquired slight to moderate improvement in all operative cases. Two cases with skeletal traction, however, became more aggravated. Indication of operation has much controversies as yet. A Major problem at present falls on the difficulty of functional recovery.

Three patients developed subdural pneumocephalus after undergoing posterior fossa surgery performed in sitting position. The mechanism for entry of air into the intracranial compartment is analogous to the entry of air into an inverted bottle. As the fluid pours out, air bubbles to the top of the container. A brow-up lateral skull radiograph with a horizontal beam provided prompt diagnosis and confirmed brain displacement as well as computerized tomography did. Tension pneumocephalus appears to be another potential complication of posterior fossa surgery in sitting position. This condition is easily diagnosed and treated, and should be considered whenever a patient fails to recover as expected following posterior fossa surgery.
C_57BL/6계 생쥐와 Nude계 생쥐의 오금림프절내 림프소절 및 종자중심의 분포에 관한 3차원적 연구
지연근,이원규,안희경 慶熙大學校 1992 論文集 Vol.21 No.-
This study was aimed to clarify the distribution of lymph follicles and germinal centers in the lymph nodes of the C_57BL/6 and nude strain mice. Male adult mice were used in this study. After animal were sacrificed, the right popliteal lymph nodes were removed and fixed in Zenker-formol solution for 3 hours and embedded in JB-4 resin. One of every two section, cut 3㎛ in thickness serially, was stained with May-Gru‥nwald and Giemsa solution. The results obtained from this study were as follows; 1. The number of lymph follicles per popliteal lymph node was average 11.25 C_57BL/6 mice but, the number of lymph follicles in nude mice was 20.25. In C_57BL/6 mice major distribution(8.5) of the lymph follicles situated in peripheral cortex overlying the unit(PCOU). In unde mice major distribution(14) is peripheral cortex beyond the unit(PCBU). 2. The thickness of most lymph follicles was between 0.01-0.19 mm in C_57BL/6 mice. But in nude mice the thickness of most of lymph follicles was between 0.20-0.39mm 3. The number of lymph follicies contained germinal center was 8.75 in nude mice. But C_57BL/ 6 mice was not observed germinal centers. 4. The average number of deep cortex is 1.5 and shape is semiovoid in C_57BL/6 mice. Spherical shaped deep cortex was observed and the number of that is one in nude mice. In stained section low density deep cortex was observed in nude mice specifically. 5. The size of lymph follicle in C_57BL/6 mice is 0.405mm and in nude mice 0.795mm
전두엽에 발생한 신경절교종(Ganglioglioma) 1예 : 증례 보고
지연근,김태성,김광명,김국기,이봉암,임언,지제근 대한신경외과학회 1983 Journal of Korean neurosurgical society Vol.12 No.2
A case of ganglioglioma is presented. A 2-year-old Korean male was admitted with chief complaint of generalized seizure from the age of 15 days. Neurologically, delayed speech development and mild monoparesis of right upper extremity he had. Brain CT revealed the ill defined round calcific density on left frontal lobe with mild dilatation of frontal horn of left lateral ventricle. EEG showed the single and poly spike wave on left cerebral hemisphere. The tumor mass was grayish white in color and rubbery hard in consistency with relatively good demarcation from the adjacent normal brain cortex. Histological diagnosis was a ganglioglioma with calcification. Following subtotal removal, the patient had an uneventful recovery.
