We found nuclear deformation lymphocytes with increased heterochromatin and impaired thymus epithelium cells with increased lysosomes and deformation of mitochondrias . ( 4 ) effects on mouse liver of so2 challenge : so2 can cause significant liver injury . he staining showed several kinds of necrosis of liver including spot necrosis , focal necrosis and submassive necrosis infiltrated with lymphocytes , monocytes , few neutrophils and eosinophils ; tem observation showed fatty degeneration with dispersion of fatty droplets and dilation of rough endoplasmic reticulums , acid degeneration with significant hyperplasia of mitochondrias , necrosis of hepatocytes with karyorrhexis and other organelles losing their normal structure ( 4 )二氧化硫染毒對小鼠肝臟的組織學結構有明顯影響,可引起肝臟點狀壞死、灶狀壞死甚至片狀壞死,伴隨不同程度的炎性細胞浸潤;透射電鏡觀察發現二氧化硫可引起肝細胞脂肪變性、嗜酸性顆粒變和壞死,脂肪變肝細胞中可見大小不等的脂滴存在,嗜酸性顆粒變肝細胞中可見線粒體明顯增生,壞死肝細胞可見細胞核結構破壞,細胞器減少,細胞膜不完整。 |

Therefore , the differences of the amount of the heterochromatin of in each species is high , and even the difference exists in the same species from different regions 但不是每個種都有端帶和居間帶。因此,各個種的結構異染色質含量差異較大,甚至同一個種不同地理種群間都有所不同。 |
|
During this process , a series of modification appeared on the xi , which led to the formation of stable heterochromatin that can be inherited steadily in cell duplication 失活的染色體上面往往發生一系列的修飾,導致產生非常穩定的異染色質且能在細胞復制的過程中穩定遺傳。 |
|
Euchromatin is thought to be actively involved in transcription and therefore protein synthesis , while heterochromatin is inavtive 異染色質由于折疊壓縮程度高,所以被堿性染料染色時著色較深。 |

Aberration analysis of chromosome 9 heterochromatin 9號染色體異染色質區的變異分析 |
|
The origin of such large amounts of constitutive heterochromatin and their role in karyotype evolution and speciation remain a mystery . 如此大量的結構異染色質的來源及其在染色體組型進化和物種形成中的任務仍是一個謎。 |
|
Heterochromatin has shown to be composed largely of short repeated polynucleotide sequences . 異染色質大部分是由短而重復的多核苷酸序列所組成的。 |
|
Chromosome material with exhibits of such behaviour is called heterochromatin . 表現這種現象的染色體物質叫做異染色質。 |
