孫成源,安永泰 경남대학교 환경문제연구소 1987 환경연구 Vol.9 No.-
The dirstribution pattern of the distoma (Fasciola hepatica) which is Parasitic on the livestock and man was surveyed in Kyung nam area with 3608 samples of cattle. The results were as followings. The overall infection rate was 4.9%, as 6.5%, 3.4%, 4.0%, and 9.0% for the samples collected in Masan, Ulsan, Kimhae, and Chinju area respectivelly. The infection rate of the Fasciola hepatica was analysed by raising method, aga, sex, season, and infected organ. The analysis by rasing method showed that the infection rate of the beef-cattle raised mainly with commercial feed was only 0.6 per cent while that of the farm-cattle raised mainly by pasturage was 34.4 per cent. The analysis by age showed the increasingly high infection rate with aging, i. e. no infection of 1~2 years samples, 2.4% of 3 years ones, 26.2% of 6 years ones, and 42.9% of 7 years ones. Strangely 8 years samples showed only 14.3% infection. The analysis by sex showed the infection rate of 94.8 per cent for females and 5.2 per cent for males. The analysis by season showed the rate of 4.6 % for summer samples (Jul. ~ sep.) and 9.0% for winter ones (Feb. ~ Mar.). The analysis by infected organ showed that the highest infection rate of 77.4% for the gall duct and the lowest of 2.8% for the blood vessels.

馬山 및 慶南 宜寧郡 嘉禮面 一帶에 捿息하는 시궁쥐의 重金屬 含量 調査
孫成源,李浩源,金洋 경남대학교 환경문제연구소 1985 환경연구 Vol.7 No.-
This study was carried out to investigate the heavy metal pollution in each organ of Rattus norvegicus norvegicus collected in Masan and Garye-myeon, Uiryong-gun, in May and October, 1984. Pb and Cd were much contained in their bone, Cr in their blood, and Zn in their fur and gut. Pb and Mn in Garye-myeon were more contained than in Masan. Cd, Cu, Cr, and Zn between Garye-myeon and Masan were similarly contained.

Spermiogenesis in the Korean Daubenton's Bat(Myotis daubentonii ussuriensis)
손성원 한국발생생물학회 1997 발생과 생식 Vol.1 No.1
To investigate the process of spermiogenesis of the Korean eastern Daubenton's bat, Myotis daubentonii ussuriensis, the testis obtained from mature male bats was studied by transmission electron microscope and were based on the variety and diagnostic characters of cell organells. The results obtained from the present study are as follows. According to the differentiation of the cell organells, the spermiogenesis of the Korean eastern Daubenton's bat, M. d. ussuriensis, was divided into Golg, cap, acrosome, maturation and spermiation phases. Besides, these Golgi, cap, acrosome, and maturation phase were subdivided into the steps of early and late phases repectively and matruation phase was subdivided into step of early, mid and late phases. Therfore, the spermiogenesisof M. d. ussuriensis has been divided into a total of 11 phases. The chromatin granules began to condense at the early cap phase, regularized at the acrosome phase, and a perfect nucleus of sperm was formed at the maturation phase. The chromatoid body was occurred in the upper cytoplasm of nucleus at the early Golgi phase, and it was accurred the posterior cytoplasm of the nucleus at the early maturatio phase. The formation of sperm tail began to be develop in the early golgi phase, and completed at the spermiation phase. The fiber structure of middle piece was consisted of nine outer doublets and two central singlet microtubules and Nos. 1, 5, 6 and 9 in the outer dense were larger than the others(2, 3, 4, 7, 8).

한국산 집고양이(Felis domesticu)에서의 정자변태
손성원,이정훈최용만정영모 한국통합생물학회 1994 동물학회지 Vol.37 No.3
성숙한 한국산 집고양이(Felis domesticn)의 정자변태 과정을 알아보기 위하여 정소 및 부정소의 조직을 채취하여 광학현미경과 전자현미경으로 관찰한 결과는 다음과 같았다. 1 세포 구조의 차이에 따라 한국산 집고양이의 정자변태과정을 출지, 두모. 첨체. 성숙 그리고 이탈단계로 구분하였는데. 즉 골지, 첨체 및 이탈단계를 각각 전 ·후기로, 두모단계는 전 ·중 ·후기로 성숙단계는 1단계로 하여 전체를 10기로 나눌 수 있었다. 2 정자의 꼬리는 두모중기부터 형성하기 시작한다. 3 염색질 과립은 골지단계에서 응축되기 시작하여 정체후기에서 구형의 형태로 진행되고 성숙단계에서 소멸된다.

한국산 등줄쥐(Apodemus agrarius coreae)에서의 정자변태
손성원,이정훈 한국통합생물학회 1995 동물학회지 Vol.38 No.3
한국산 등줄쥐의 정자변태 과정을 알아보기 위하여 세정관 상피의 세포분화에 따른 특징들과 정소상체 미부의 성숙정자의 형태적 특징들을 조사하여 다음과 같은 결론을 얻었다. 세포구조물의 특징에 따라 골지, 두모, 첨체, 이탈단계는 각각 전, 후기로 구분하였고 성숙단계를 1단계로 하여 한국산 등줄쥐의 정자변태의 전 과정을 9기로 나눌 수 있었다. 핵질의 변화에 있어서, 염색질 과립들은 두모단계에서 응축하기 시작하여 첨체단계에서 구형의 형태로 진행되고, 성숙단계에서 균질화하여 완전히 정자의 핵을 형성하였다. 정자두부는 낫꼴모양을 가지며, 중편부의 외측섬유는 편자모양으로 배열되어 있고, 이들 외측 섬유는 NO. 1,5,6,9가 다른 것 보다 크다. In order to study the process of spermiogenesis of the korean striped field mouse Apodemus agrorfus coreae, the cell differentiation of seminiferous epithelium and morphological features of mature sperm in cauda epididymis was examined and the results are as follows: Spermiogenesis was divided, according to the features of cell structure; Golgi, cap, acrosome and spermiation phases were further subdivided into two steps of early and late phases respectively, and maturation phase has only one step. Hence, the spermiogenesis consists of nine phases. in the changes of the chromatin in nucleus, the chromatin granules began to be condensed in the cap phase and the condensation proceeded to form a globular of nucleus at the acrsome phase. Finally, the chromatin regularization was completed and perfect nucleus of sperm was formed at the maturation phase. Sperm head had the falciform, and the outer dence fibers of middle piece were arranged in a horseshoe fashion. The outer dence fiber number 1, 5, 6 and 9 was larger than other fiber number 2, 3, 4, 7, 8.

손성원,이정훈,신화정,최병진,Son, Sung-Won,Lee, Jung-Hun,Shin, Hwa-Jeung,Choi, Byung-Jin 한국현미경학회 1995 Applied microscopy Vol.25 No.1
In order to clarify the process of spermiogenesis of the large-footed bat, Myotis macrodactylus, the testis and the epididymis obtained from mature male bats were examined by electron microscope. Based on the variety and diagnostic characters of organells, the spermiogenesis of the large-footed bat. Myotis macrodactylus could be divided into a total of nine phases. The results obtained from the present study are as follows. 1. The spermiogenesis of large-footed bat, Myotis macrodactylus was divided according to the level of fine structural differentiation into five phases, Golgi, cap, acrosome, maturation and spermiation phases, respectively; Golgi, cap, acrosome and spermiation phases were further subdivided into steps of early and late phase respectively and maturation phase has only one step. Hence, the spermiogenesis of the large-footed bat has been divided into a total of nine phases. 2. In the change of chromatin with nucleus, the chromatin granules are condensed in the whole part of nucleus at the late Golgi phase and completed at the maturation phase. 3. The sperm tail in the epididymis consists of nine outer doublets and two central singlet microtubles. Nos. 1, 5, 6, 9 of the outer dense fibers were larger than the others (2, 3, 4, 7, 8).
