  • Recently, the Acridine orange (AO) staining method has improved for identification of malaria parasites. Fixed and preserved blood smears of malaria patients were used for comparative analysis of AO and Giemsa stains. The AO staining method required less time and was more sensitive under lower magnification than the Giemsa staining method . The AO staining method provides an alternative to Giemsa for malaria diagnosis in the field and laboratory.

  • The application of Giemsa technique to stain compressed diaphragm samples obtained from rodents experimentally infected with Trichinella spiralis is described. Diaphragm samples from rats heavily infected with 20 muscle larvae per gram of body weight(20 ML/gbw) were cut into several pieces and stained with Giemsa; on the other hand, whole diaphragms from slightly infected mice(1 ML/gbw) were also stained with Giemsa. Besides, muscle samples were also stained with Giemsa. Observation at 10 $\times$ magnification revealed that both ML and nurse cells(NC) look as bluish structures clearly contrasting with the pinkish color of the non-infected muscle fibers. NC in the diaphragms of mice could be easily observed at naked eye as blue points contrasting with the pink surrounding areas formed by the non-infected muscle fibers. Among NC observed in the diaphragms of rats infected with 20 ML/gbw, 4.4% was multiple infection. These findings were confirmed in sectioned and hematoxylin-eosin stained specimens. This data could be usefulness for a rapid diagnosis of trichinellosis in post-mortem mammals without magnification procedures.

  • A Giemsa C-banding method was used for the identification of somatic chromosomes and heterochromatic knob position in Korean indigenous waxy com (Zea mays L.). 5 inbred stocks were examined and their heterochromatic knob numbers ranged from 6 to 12. In comparison of homologous chromosomes of two stocks of YS-1 and MY-1, knob numbers, knob positions, arm ratios and relative length of chromosomes were different between the genotypes. The length of homologous chromosomes in YS-1 were generally larger than those of MY-1. The Giemsa method was proved to be useful for the identification of somatic chromosome and a C-banded diagram showing knob positions, arm ratios and relative length of chromosome could be used as a good tool to compare the characteristics of chromosomes of Korean indigenous waxy corn stocks.

  • A Giemsa C-banding method was used for the identification of somatic chromosomes of Korean indigenous maize(Zea mays L.). Two Korean indigenous maize stocks and an American hybrid maize for comparison were examined. Ten deeply stained heterochromatic knobs whose position and size were different between the genotypes, two satellites and interstitial bands were observed. The length of homologous chromosomes compared by the relative lengths of chromosomes presented as a percentage of the length of chromosome 10 were different between the genotypes. The Giemsa method proved to be useful for the identification of somatic chromosomes and for the characterization of different stocks of Korean indigenous maize.

  • In this study, whether Giemsa staining solution can accurately determine bacterial contamination of liquid spawn for Flammulina velutipes in a short period of time was investigated. Giemsa solution staining cells of blood, bone marrow, lymph node, malaria parasites, rickettsia et al. was prepared by dissolving basic methylene azul and methylene blue, and acidic eosine in methyl alcohol-glycerine. Supernatant samples of Flammulina velutipes liquid spawn cultured under explosive aeration were placed on a slide, mixed with Gimesa solution and examined with optical microscope after staining. In 40 to 60 seconds bacterial cells were distinguishable from soybean meal residual and hyphal cell fragments. Thus we conclude that microscopy using Gimesa staining solution is a quick, simple and accurate method for the mushroom growers to effectively use to detect bacterial contamination of the liquid spawn.

  • A technique is described for producing high resolution G- and R-banded chromosomes in human peripheral lymphocyte cultures. Cultured lymphocyte cells were exposed to ethidium bromide ($10{\mu}g/ml$) and colcemid ($0.02{\mu}g/ml$) each for 2.5h and 0.5h prior to harvest for high resolution G-banded chromosomes. High resolution R-band patterns were obtained by BrdU substitution which was revealed by the fluorochrome-photolysis-Giemsa staining technique. These methods are easy to perform and highly reliable. The data on relative length of chromosomes at the four mitotic stages are presented in units of percentage of haploid autosome length. The characteristic patterns of GTG-bands (G-bands after trypsin and Giemsa) and RBG bands (R-bands after BrdU and Giemsa) were analyzed.

  • Firstly, we compared the two staining techniques, Giemsa and Acridine orange, to determine micronuclei on samples of cultures of five healthy human peripheral blood lymphocytes after ${\gamma}-irradiation\;(^{137}Cs)$ in dose ranges of 0 to 800cGy. It was found that the Acridine orange staining method gives more reliable results than the usual Giemsa staining method in micronucleus tests. Moreover, the frequency of micronuclei in cytokinesis-blocked human B-lymphocytes was studied after in vitro irradiation in dose ranges of 0 to 50cGy. After setting and separating the B-lymphocytes, the frequency of radiation-induced micronuclei were observed as the end-point markers for the low-dose radiation dosimetry after staining with Giemsa and Acridine orange dyes. The micronuclei frequency in B-lymphocytes was significantly elevated from 10 to 30cGy ${\gamma}-irradiation$. The determination of micronuclei in B-lymphocytes after staining with Acridine orange was higher than that of Giemsa. The frequency of micronuclei in B-lymphocytes was observed to be at least two times higher than those of T-lymphocytes Giemsa in dose increasing. Therefore, the determination of low-dose radiation-induced micronuclei in B-lymphocytes after staining with Acridine orange is likely to have the greatest potential in the estimation of low dose radiation exposure.

  • 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.

  • This paper describes the design and implementation of personal computer assisted karyotyping system of Giemsa stained chromosomes. The system consists of an Image Acquisition Module being capable of $256 {\times} 256$ pixels and its relevent software modules optimized for karyotyping. The results of karyotyping using this system with an image of chromosomes taken from the Rana Amurensis are acceptable. As a result of this study we can save our load oweing to the conventional hand- karyotyping and the high-cost computer.
