홍석후의 『신편생리교과서』(1906) 번역과 그 의미

Hong Seok-hoo, who took charge of Jejungwon (濟衆院), was successful in translating Jiro Tsuboi’s book titled “新編生理敎科書 (1897)” and publishing it with a title of “New Edition of Physiology Textbook(신편생리교과서)” in 1906. Jiro Tsuboi, the original author of that book, was a doctor having majored in Hygienics in Germany and was also known to have done pioneering work in Hygienics and Occupational and Environmental Medicine in Japan. At that time, he wrote that book for the purpose of teaching his students at Ordinary Middle School(尋常中學校) and Normal School(尋常師範學校). Therefore, it was not intended as a Physiology textbook for medical students, but an introductory book explaining Physiology with a wide range of subjects including hygienic matters in a broader sense. Hong Seok-hoo made an almost complete translation of the “New Edition of Physiology Textbook.” While editing the book, however, he changed some of the most Japanese-style contents to meet the Korean conditions then, and made up for some insufficient contents with reference to the original author’s other books. Although it was not included in an original version of that book, he also compiled a physiology dictionary in order to help Korean readers acquire medical terms in a more systematic way. Just like other textbooks of Jejungwon, the “New Edition of Physiology Textbook” was also put into Korean only. Hong Seok-hoo accepted Japanese-style medical terms, but also changed some of them or coined new words, considering the Korean circumstances then. He seemed to do so in an effort to introduce Western medicine in a more independent way while overcoming his limitations of translation. In particular, this book criticized that a long-term use of cosmetics might cause a serious lead poisoning from a Christian viewpoint, saying that a God-created human body should be kept intact as it is. In addition, in the course of reediting premodern books, the term “Lord” was changed into “God,” which is considered a kind of fusion between traditional values and missionary medicine. While translating books, Jejungwon could put such fusion into practice because it was a hospital established under the banner of the propagation of Christianity. Besides the “New Edition of Physiology Textbook,” at least five physiology textbooks were also translated into Korean in the last years of Daehan Empire for the purpose of teaching students modern subjects like Physiology, Health and Hygienics in educational institutions including Boseong School, Hwimun School and Soongsil School. On the other hand,the “New Edition of Physiology Textbook” was first translated at the end of Daehan Empire in order to foster more professional doctors in medical schools compared to those schools. In this respect, by translating the “New Edition of Physiology Textbook,” Jejungwon can be considered as playing a pioneering role in translating Physiology textbooks in the late Daehan Empire.ope

해방 직후 북한의 의학교육에 관한 연구 : 평양의학대학을 중심으로

이 연구에서는 해방 후 현재까지 북한 의학교육의 중심적 위치에 있는 평양의학대학에 초점을 맞추어 그 설립 과정, 교수진, 교과목 등을 한국전쟁시 노획된 평양의학대학 이력서, 평양의학대학 졸업생들의 기록이 담긴 평의(平醫)를 중심으로 하고, 이외에 조선중앙년감, 인민보건 등의 잡지, 그리고 그들이 소장하고 있는 일부 자료를 이용하여 상세하게 분석 재구성해 봄으로써, 북한 정권 초창기에 의학교육이 어떻게 정립되었으며 어떤 특징을 갖고 있었는가를 밝히고자 한다.ope

Endotoxin-neutralizing antimicrobial proteins of the human placenta

Microbial colonization and infection of placental tissues often lead to adverse pregnancy outcomes such as preterm birth, a leading cause of neonatal morbidity and mortality. The fetal membranes of the placenta, a physical and active barrier to microbial invasion, encapsulate the fetus and secure its intrauterine environment. To examine the innate defense system of the human placenta, antimicrobial peptides were isolated from the fetal membranes of human placenta and characterized biochemically. Two salt-resistant antimicrobial host proteins were purified to homogeneity using heparin-affinity and reversed-phase HPLC. Characterization of these proteins revealed that they are identical to histones H2A and H2B. Histones H2A and H2B showed dosedependent inhibition of the endotoxin activity of LPS and inhibited this activity by binding to and therefore blocking both the core and lipid A moieties of LPS. Consistent with a role for histones in the establishment of placental innate defense, histones H2A and H2B were highly expressed in the cytoplasm of syncytiotrophoblasts and amnion cells, where the histone proteins were localized mainly to the epithelial surface. Furthermore, culturing of amnion-derived WISH cells led to the constitutive release of histone H2B, and histones H2A and H2B contribute to bactericidal activity of amniotic fluid. Our studies suggest that histones H2A and H2B may endow the epithelium of the placenta with an antimicrobial and endotoxin-neutralizing barrier against microorganisms that invade this immune-privileged site.

Glucose absorption and utilization by rat embryos

There is little doubt that glucose plays a significant nutritional role in early somite embryos. The high glucose utilization of anaerobic glycolysis drops as the activity of the Kreb's cycle and terminal electron transport increase. Concurrently, maturation of mitochondrial cristae and dependence on oxygen supply are taking place. The neuroepithelium of the early somite rat embryo responds in vitro during culture by microvilliar lengthening when exposed to glucose levels of 50 mg/dl or more. At lower glucose concentrations both in whole embryo culture and inside the closed neural tube the microvilli are shorter. Lengthening of the microvilli at room temperature is produced only by d-glucose and 2-deoxyglucose, two hexoses that are absorbed and phosphorylated. Cytochalasin D which disrupts actin polymerization causes ballooning of the microvilli. A role of this microvillar elongation in degenerative changes seen in uncontrolled diabetes and on function of the immune system is proposed. The amniotic cavity is one major portal of entry for glucose during the early somite embryo stage. The 7-fold increase in volume of the amniotic cavity after day 10 allows the rat embryo to convert its axis from dorsal to ventral flexion.ope

Timetable for upper eyelid development in staged human embryos and fetuses.

In this study, we examined the development of the upper eyelids to provide a basic understanding of gross anatomical structures and information relative to mechanisms of congenital anomalies in the upper eyelids. We studied the upper eyelids by external and histological observation in 48 human embryos and in fetuses from 5 to 36 weeks postfertilization. The upper eyelid fold began to develop at Stage 18. Upper and lower eyelids fused from the lateral cantus at Stage 22, and fusion was complete by 9 weeks of development. Mesenchymal condensations forming the orbital part of the orbicularis oculi (OO), tarsal plate, and the eyelashes and their appendages, were first seen at Week 9. Definite muscle structures of the upper eyelid, such as the orbital part of the OO and the levator palpebrae superioris and its aponeurosis, and the Müller's muscle were observed at 12 and 14 weeks, respectively. In addition, orbital septum, arterial arcade and orbital fat pad, and tarsal gland (TG) were apparent at 12, 14, and 18 weeks, respectively. Opening of the palpebral fissure was observed at Week 20. In addition, we defined the directional orientation between the levator aponeurosis and orbital septum and the growth pattern of the TG. Our results will be helpful in understanding the normal development of the upper eyelid and the origins of upper eyelid birth defects.ope
