양측 뇌 기저핵에 동시에 발생한 자발성 뇌 실질내 출혈
김세훈,조태형,정흥섭,이훈갑,주정화,이기찬 대한신경외과학회 1995 Journal of Korean neurosurgical society Vol.24 No.6
Spontaneous intracerebral hemorrhage is one of the most devastating forms of cerebrovascular disease in the field of neurosurgery, and is most frequently associated with the hypertension in the distribution of the penetrating yessels, or can be secondary to other factors, like aneurysm, arteriovenous malformation, glial tumor, metastasis, infarction, anticoagulation therapy, coagulation disorders such as leukemia or thrombocytopenia. Although many cases of recurrent hypertensive intracerebral hemorrhage have been reported, bilateral simultaneous hemorrhage has not been reported. The authors report a case of bilateral simultaneous hypertensive intracerebral hemorrhage in a 62-year-old male, which was treated by conservative management.

The author observed 68 cases of the tympanic membrane perforation, who visited at the Department of Otolaryngology of Capital Armed Forces General Hospital in 1983. The results obtained were as follows; 1. The symptoms were hearing loss 56 cases(82.4%), tinnitus 50 cases(73.5%), otalgia 48 cases(70.6%), autophonia 40 cases (58.8%) in order. 2. The duration from tympanic membrane perforation to confirmation at OPD was usually within 3 days(44 cases, 64.8%). 3. The side of tympanic membrane perforated ear was usually left side in 50 cases(73.5%). 4. The location of tympanic membrane perforation was usually seen in the anteroinferior quadrant(28 cases, 41.2%) and intermediate portion (36 cases, 53.0%), and the shape of tympanic membrane perforation usually showed triangular shape(43 cases, 63.2%), and the triangular shape was about 25.5 ㏈ in air-bone gap. 5. The air-bone gap after tympanic membrane perforation was usually about 11-20 ㏈(30cases, 44.1%). 6. As nonhealing 5 cases of nonhealing tympanic membrane perforation 6 cases (8.8%) occurred within the patients of the nasal problem (12 cases) in relationship between Eustachian tube and the neighboring organs, the Eustachian tube was influenced by the diseases of the neighboring organs with symptoms (maxillary sinus and intranasal structures), and the function of Eustachian tube was disturbed, thereby the healing of tympanic membrane perforation was delayed. 7. In 44 cases visited at out patient department in 3rd day from tympanic membrane perforation, it usually occurred the transformation for the shape of tympanic membrane perforation that the triangular shape was transformed to irregular round, and the irregular round was changed to round. And the healing duration of tympanic membrane perforation was mostly closed in 10 weeks.

고혈압 및 정상혈압백서의 대동맥 평활근 세포에서 ATP-sensitive K^+ Channel에 대한 Cromakalim의 영향
김세훈,이영준,김회숙,장석종 충남대학교 의과대학 지역사회의학연구소 1997 충남의대잡지 Vol.24 No.2
To determine wherther the properties of ATP-sensitive K^+ channel (K_ATP channel) in aortic smooth muscle cells from spontaneously hypertensive rats are altered of not, the effect of a K^+ channel opener, cromakalim, on membrane currents in aortic smooth muscle cells from spontaneously hypertensive rate (SHR) and Wista-Kyoto rats (WKY) were compared, using a patch-clamp technique. 1. The internal and external K^+ were 140 and 60 mM, respectively. The currents were recorded at -70mV. The inward current was evoked by cromakalim and this current was inhibited by glibenclamide. 2. The cromakalim-evoked current was time-independent and voltage-insensitive. 3. The reversal potential of cromakalim-evoked current depended on external K^+ concentration, and this current was reversed at near K^+ equilibrium potential. 4. The cromakalim-evoked current was reduced when the intracellular ATP concentration was raised from 0.1mM to 3 mM. 5. In SHR, crmakalim-evoked current, normalized by cell capacitance, was not changed when compared to WKY. From the above results, it is suggested that cromakalim-evoked current was carried throuhg K_ATP channel and the function of cromakalim on K_ATP channel in aortic smooth muscle cells of SHR is not impaired when compared to WKY cells

이 연구는 회류수조 내에서 단순화된 물체인 원주 주위의 와류 유동을 계측하였다. 특히 실제 현상에 좀 더 가깝게 접근하기 위하여 균일한 유동이 흘러올 때에 경사각이 있는 원주주위에 와류가 항력에 어떠한 영향을 미치는지 실험으로 검증하여 보았다. 실험 장치로는 양쪽에 끝단이 반구로 되어있는 원주와 로드셀, DAQ, 컴퓨터로 구성되었다. 각각의 유속별로 항력과 항력계수를 구하여 비교하였다.

This review of upper cervical spine injuries includes 51 patients admitted to Korea University Hospital. Seoul during the period 1 Jan. 1990 to 31 Dec. 1994. The incidence of upper cervical injury was 13.6% in the 375 spine injury cases and 31.7% in the 161 cervical spine injuries. The most common type of injury was odontoid fracture, ie. 16 cases or 31.3%. The male-to-female ratio was 2.6 : 1 and the 4th decade showed peak incidence, 33 cases(64.7%) of the injuries were caused by traffic accidents. The chief complaints on admission were neck pain with limited range of motion in 39 cases(76.5%), motor weakness in 3 cases(5.9%), and sensory disturbance in 2 cases(3.9%). Operative treatment was performed in 23 patients resulted in neurologic improvement in 22 cases(95.7%) and 28 patients were managed by conservative treatment with 25 cases(89.3%) of neurologic improvement. Mortality rate of the upper cervical spine injury was 3.9%. The above represents our experience with 51 patients suffering from upper cervical injuries. Management and follow-up guidelines are also reviewed.
