Abstract: G-,C-and R-banding technique were employed in the chromosome analysis of the hu-man malignant glioma cell line SHG-44 established in our laboratory.The chromosome numbersin the examined cells ranging from 52 to 125.The value of hypertripoid cells were 86.64%,while that of hypotriploid and hypertetraploid cell were 10.42% and 4.94%,respectively.Bycomparing the real number of each chromosome with ploicexpected number in the same cell,the losses and gains of each chromosome were determined.The losses of chromosomes were those ofgroup A and B(especially 5#)and 6#,8#,9#,15#,in group C and sex chromosome(s).The gains of chromosome were 7#,11#,12# in group C and those of group D,E,F,G(espe-cially 17#).Three big submetacentric chromosomes,observed with ratrer high frequencies,ex-isted in all the examined passages.These three chromosomes were considered to be the markerchromosomes of SHG-44.
