말라리아의 진단 방법으로 흔히 사용되고 있는 Giemsa 염색법과 형광염색법중 Acridine orange(AO) 염색법을 비교하였다. 말라리아 환자의 혈액을 채취하여 Giemsa와 AO로 염색하여 각각 광학현미경 및 형광현미경으로 관찰하였다. AO 염색법은 Giemsa 염색법에 비해 저배율에서도 쉽게 말라리아 원충을 찾을 수 있어 빠르고 정확한 말라리아의 진단을 위해 Acridineorange 염색법이 더 효과적이라고 생각된다.

본 연구에서는 배양된 액체종균의 세균 오염 여부를 Giemsa 용액의 단일 염색으로 짧은 시간 안에 정확하게 판정이 가능한지를 조사하였다. Giemsa 용액은 혈액 골수 림프절 말라리아 원충 리케차 세포 등을 염색하는 것으로, 염기성 색소인 methylene azul과 methylene blue, 그리고 산성색소인 eosine을 methyl alcohol-glycerine에 녹여서 제조하였다. 그리고 팽이 액체종균의 폭기 배양액 분취하여 슬라이드에 올리고 Gimesa 용액으로 염색한 후 광학 현미경으로 검사하였다. 이 결과 40~60초 동안의 세균세포를 (팽나무)버섯(류) 균사세포의 부스러기나 잔존 대두박 등과 구별할 수 있었다. 이 Gimesa 용액을 이용한 염색 및 검경방법은 빠르고 간편하며 정확하므로 액체종균을 사용하는 버섯재배 농가에서도 세균 오염을 효과적으로 동정(감지)하는데 이용할 수 있다고 생각한다.

방사선에 의해 유도되는 사람 말초혈액 림프구 미소핵 관찰빈도를 높이면서 생물학적 선량평가법으로서 활용 가능성을 확인하고자 본 연구를 수행하였다. 우선 5명의 건강한 사람으로부터 혈액을 제공 받아 선량영역을 0에서 800cGy로 하여 감마선$(^{137}Cs)$을 조사 한 후 김사와 아크리딘 오렌지 형광 염색하고 미소핵 출현빈도를 비교하였다. 아크리딘 오렌지 염색법을 이용하여 미소핵을 관찰하였을 때, 김사 염색법에 비교하여 적갈색의 비특이성 과립과 녹황색의 DNA가 붉은색의 세포질을 배경으로 명확히 구별되었을 뿐만 아니라 선량이 증가하면서 검출율도 높았다. 아울러, 말초혈액 T와 B-림프구에 대하여 선량영역을 0에서 50cGy로 하여 방사선을 조사한 후 미소핵 출현빈도를 아크리딘 오렌지 염색하여 김사염색과 비교한 바, B-림프구에서 선량이 증가하면서 적어도 2배 이상 높게 관찰되었다. 본 실험 결과, 사람 말초 혈액 B-림프구를 대상으로 한 아크리딘 오렌지 형광염색 미소핵 분석법은 저선량 방사선 인체영향 평가나 과피폭 선량추정시 활용이 가능 할 것으로 생각된다.

On the basis of karyotypic analysis performed by conventional staining and Giemas C-banding technique, cytological relationship was inferred for 21 lines of Paeonia lactiflora Pal. cultivated in Korea. It was very difficult to infer their organized karyotypic classification system using the composition of somatic chromosomes involving sat-chromosomes, relative length of chromosomes, arm ratio and karyotypic formulae by conventional staining. From the distribution and number of Giemsa C-bands on the chromosomes b and c, 21 lines can be subclassified into 5 groups. It seems that the karyotypic polymorphism is observed in 21 lines of cultivated P. lactiflora because peony mainly propagates by outbreeding.

A technique to improve the analysis of micronuclei(MN) in lymphocytes as a cytogenetic indicator is reported. For the purpose of diminishing the variation of the result from individual reader and making it easier to distinguish accurately a cytokinesis blicked(CB) lymphocyte and micronuclei, we tried a modified one-step silver staining technique as a method for detection of the argyrophilic nucleolar organizer region(AgNOR) with or without conventional Giemsa stain in the slide from CB method. Compared with the conventional Giemsa stain, the preparation processed with this method are especially useful for the accurate analysis of MN of cultured lymphocyte with cytochalasin B. This method will be a useful technique for automated calculation of MN.

한국산 박새속 조류 Porus major(박새), Porus atter(진박새), Porus poiustris(쇠박새), Parus varius(곤줄박이)의 핵형을 일반염색 방법으로 분석한 결과 4종의 염색체 수는 모두 2n=78∼80으로 나타났고, 성 염색체를 포함한 7쌍이 macrochromosome, 그 외 32∼33쌍이 microchromosome이었다. 종간 차이를 나타내는 염색체는 5번째 염색체와성염색체인 Z·W-염색체였다. 이러한 핵형의 차이는 5번째 염색체에서는 pericentric inversion, 성 염색체에서는 전좌에 의한 것으로 생각된다. The chromosomal analysis of Pows major, Paws after, Paws palustris and Paws vorius of the genus Paws in Korea were performed by conventional Giemsa staining method. The diploid number of four species were 2n=78-80, and there were 7 pairs of macrochromosomes and 32 or 33 pairs of microchromosomes. The 5th and Z·W-chromosomeswere distinctly different between interspecies. Probably these karyological differences were speculated by pericentric inversion in 5th chromosome and translocation in Z·W-chromosomes.

한국산 박새속 조류 Porus maior(박새), Parus ater(진박새), Parus palustris(쇠박새), Parus varius(곤줄박이)의 핵형을 C-banding 방법으로 분석한 결과 ZZ-ZW 염색체를 동정, 확인할 수 있었으며, 구조적 이질염색질의 부위가 일반염색 방법에 의한 핵형 비교에서 보다 종간에 더 많은 차이를 나타냈다. 그러나 일반염색 방법과 C-banding 방법 만으로는 4종간의 종분화 기작을 추측할 수 없었다. The chromosomal analysis of Paws motor, Paws ater, Pahs palustris and Pows varius of the genus Paws in Korea were performed by C-handing method. The identification of sex chromosones was ascertained and the part of constitutive heterochromatin was more different between interspecies than by conventional Giemsa staining method. However, conventional Giemsa staining and C-banding methods could not explain mechanisms of speciation between four species.

The object to this study is to identify the genus and species of the microfilariae which were recently found in the area of Youngju-Gun. THe identification of the microfilariae was made on the morphologicla aspects. 1. Blood samples were collected through vena punction from known microfilariae carriers living in the newly confirmed filaria endemic area of Youngju0Gun in Jyongsang Pukdo Province. Youngju-Gun is located in the mountainous central part of Korean Peninsula. 2. The following fixation and staining techniques were applied. (1) Fixation by drying in the air, followed by staining with Azeo or Giemsa. (2) Knott's fixation method (2% formalin), followed by staining with Azur II. 3. A comparative study of the body length of the microfilariae after different fixation and staining techniques were applied. (1) Knott's fixation method followed by staining with Azur II : average body length found was 28.4$\mu$. (2) Dry fixation followed by staining with Giemsa : average body length found was 209.4$\mu$. (3) Dry fixation followed by staining with Azeo : average body length found was 205.4$\mu$. 4. The locations of the different body cells were measured in 60 individuals of microfilariae in the wet preparation fixed by Knott's method and stained with Azur II. The distance of the different body cells to cephalic apex of microfilariae was measured and calculated as a percentage of the total body length. The average results are as follows : BNC , 3.04% ; N, 22.74%, EP, 31.4% ; EC, 37.77%, G1 cell , 67.94%; G2 cell, 73.54% : G3 cell , 75.55% ; G4 cell, 77.65% ; AP, 82.02%%. 5. As a result of the above findings the microfilariae found in the above mentioned area could be identified as Brugia malai(BRUG, 1927) BUCKLEY, 1960.

Diagnosis of cryptosporidiosis is currently confirmed by the detection of the oocysts or endogenous stages in fecal or tissue samples. Various conventional staining methods and serodiagnostic techniques have been reported, but the latter has far been limited to a few laboratories. Cryptosporidium has recently been reported in mice and chiekens in Korea, but there has been no report on staining methods to the oocysts. The present study was performed by light and scanning electron microscopic observations, and discussed with staining properties of four conventional methods such as dichromate solution floatation method, Carbol fuchsin stain, Auramine-O stain and Giemsa stain method. Cryptosporidial oocysts were isolated from the laboratory mouse. In tissue sections of duodenum, jejunum, ileum, cecum and upper colon, numerous very small, basophilic bodies were observed on the border of mucosal epithelial cells. In scanning electron microscopic observations, a few of developmental stages of Cryptosporidium were seen. Two types of thick and thin-walled oocysts were recognized in the intestinal contents. Mean size of its were $5.19{\pm}0.23{\times}4.31{\pm}0.32{\mu}m$ and $5.14{\pm}0.25{\times}4.27{\pm}0.4{\mu}m$, respectively. Carbol fuchsin and Auramine-O stain methods are recommended as the satisfactory ones for the identification of Cryptosporidium oocysts. Giemsa stain was also recommended as available in the laboratory, because a few of developmental stage fo Cryptosporidium could be seen by it.
