흰쥐 복직근과 대흉근 근섬유 유형에 대한 조직화학적 연구
민병운,박경수,노영복 조선대학교 기초과학연구소 1989 自然科學硏究 Vol.12 No.1
포유동물인 흰쥐의 대흉근과 복직근에 대한 근섬유 특성 및 근섬유 유형별 빈도를 조사하기 위하여 1988년 7월 2일~1988년 10월7일 조직화학적 및 각종 효소조직화학적 염색을 시행하여 조사한 바 다음과 같은 결론을 얻었다. 1. H-E 염색에 의한 근섬유의 유형별 구분은 불 명확하였으나, PAS 염색에서는 양성 반응의 정도에 따라서 세가지 유형으로 구분되었다. 2. Reversed myosin-ATP ase 염색과 SDH염색에서는 TypeⅠ, Ⅱa, Ⅱb의 세가지 유형의 근섬유형이 구분되었다. 그러나 typeⅡ와 Ⅱb의 유형별 빈도는 SDH염색과 Reversed myosin-ATP ase 염색상 상당한 차이가 있는 것으로 관찰되었다. 3. 포유동물인 흰쥐의 복직근과 대흉근의 근 섬유형 구성비는 부위에 따라서 상당한 차이가 있었다. In order to study properties and individual proportions of muscle fiber types on the pectoralis major an rectus abdominis muscle of the rat, vertebrates, histological and each kinds of enzyme histochemical stain (were performed). The following results were obtained : 1. Differentiation of muscle fiber types was not evident in H & E stained specimen. However, three types of muscle fibers were evidently differentiated in PAS stained sections according to the degree of positivity. 2. Muscle fiber of three types (typeⅠ, Ⅱa and Ⅱb) were differentiated in reversed-ATP ase and SDH stain. However, there were considerable difference between SDH and reversed-ATP ase stain properties in proportion of typeⅡa and Ⅱb. 3. The constituent proportions of muscle fibers in rectus abdominis and pectoralis major muscle of the rat were remarkably different according to the portions.

Author studied clinicopathological findings of 300 appendectomized cases at this clinic for the past two years and following results were obtained. 1) Sex incidence was 1 : 1.2. (Male: Female) 2) 151 cases (50.4%) were operated upon within 24 hours from the onset of the disease. 3) Leucocytic counts over 10.000 were found in 12l cases (70.3%). 4) 36 cases (12%) were perforated, the site mostly being at the tip of the appendix(41.7%). Among 300 appendectomized cases, 92 cases(30.7%) were appeared to be acute suppurative. 5) The average length of the appendix was 6.7±1.35 cm. and 141 cases(44%) were ranged 6.1 to 8.0 cm. in length. Width was l.1±0.352 cm. in an average and 48.3% were ranging from 0.6 to 1.0 cm. 6 ) The contents of the appendiceal lumen were as follows; fecal material being in 218 cases(39.3%), mucus in 96 cases(32%), pus in 60 cases(20%), fecalith in 20 cases(6.7%) and ascaris in 6 cases(2%). 7) In 100 cases, the parasitic ova were examined from the material in the lumen of the appendix and 42 cases(42 % ) had trichocephalus trichiurus, 23 cases(23%) ascaris, 14 cases(l4% ) trichocephalus orientalis and 12 cases(l2%) anchylostoma duodenalis. 8) In mild, subacute or chronic cases, trichocephalus trichiurus was more frequently found and in relatively severe, necrotic or suppurative cases, ascaris was found more prevalently. 9) Bacteriological study from the lumen of the appendix was done in 50 cases and 14 kinds were detected, E. coli being most predominant(32 cases 45%). 10) Luminal study by means of barium injection was done in 155cases and revealed the lumen to be occluded by fecal material being in 51 cases(44.4%), by stricture due to fibrosis in 46 cases(40%) and neither occlusion nor stricture in 18 cases(15.7%). Occlusion by fecal material was mostly found in the radix and stricture due to fibrosis mostly in tip.
各種 胃 手術이 胃Pepsin値에 미치는 影響에 關한 實驗的 硏究
閔丙雲 우석대학교 의과대학 1967 우석의대잡지 Vol.4 No.1
Various factors must be contributing in initiating and perpetuating peptic ulcers in the duodenum as well as in the stomach besides gastric acidity. Among others, the pepsin secretion in the stomach may have something to do with gastric free acidity together with amount of gastric secretion. Pepsin values, free acidity and amount of gastric secretion were studied one month following gastrostomy, vagotomy alone, antrectomy, vagotomy plus antrectomy, pyloroplasty alone, vagotomy plus pyloroplasty and subtotal gastrectomy. For each group, 10 mongrel dogs were used except for the antrectomy group in which 9 dogs operated. Each sample was taken every 30 minutes 8 times following 24-hour fasting. Pepsin was examined through Anson's Hemoglobin method hydrochloric acid To¨pfer-Michaelis method. Results are summarized as follows; 1. Pepsin reduction was maximal in the group of subtotal gastrectomy, the mean pepsin value of which showed 3.5±0.8 p.u./ml., that is, 97.8 percent of the control group in which the mean pepsin value was 156.8±16.3 p.u./ml. The mean value of pepsin in the group of antrectomy plus vagotomy group was 8.6±1.3 p.u./ml., that is, 94.5 percent reduction, whereas, in the antrectomy alone group, the mean value 15.7±2.4 p.u./ml., that is, 90.0 percent reduction. 2. In the pyloroplasty alone group, the mean pepsin value was 95.8±12.8 p.u./ml.. When pyloroplasty was combined with vagotomy, the value dropped to 23.7±3.2 p.u./ml. In other words, pyloroplasty alone is not much effective in reducing pepsin value unless vagotomy is combined. 3. The least reduction in pepsin value was observed in the group of vagotomy alone. 4. Free acid was nil in the subtotal gastrectomy group whereas the mean value of free hydrochloric acid in the control group was 42.2±6.8 cl.u./ml.. Ninety-eight percent reduction was noted in the vagotomy plus antrectomy group and 96.6 percent reduction in the antrectomy alone group. In the group of pyloroplasty plus vagotomy, 96.6 percent reduction of hydrochloric acid was noted. 5. Fasting mean pepsin value and free acidity in the respective group were positively correlated (r=+0.84 p.<0.001). 6. The amount of gastric secretion following various gastric operations was approximately 10 ml, in 30-miunte intervals.

To verify operation of relay is a difficult job for relay engineers. This paper reports the development of logic simulator. Fault data is generated from EMTP and system information generator. The developed system has a universal characteristic that can deal with any relay logic. This system has a module that can simulate relay to be constructed on logic generator. Therefore, user can check behavior of relay. This system is goint to use on the develpment for ideal relay

Neurinoma of digestive tract is a rare entity. Author encountered one case of stomach neurinoma and duodenal neurinoma respectively and herein reported. Presenting symptoms are abdominal pain, palpable intraabdomjnal mass and melena with emaciation. Characteristic feature is contrast media on X-ray film, which leaked out from lumen, simulating internal fistula, into tumor mass which appeared to be compressing the organ. Upon resection, the tumor appeared to be rather plump. On sectioning, cut surface contained several cavities, some of which communicating with lumen of organ from which it is originated. Moderate resection gave good results in both though stomach neurinoma was disclosed to be malignant. Literatures are reviewed.

When faults occur in power systems, the protective relay plays a roles of protecting power systems according to its setting values. There it is important that the protective relay have high selectiveity and sencitivity performance in power system by correct setting the relays. This paper proposed a method to testify the reliability of digital relay as simulating the response of relay at the faults in the real power system operation environment.
