Results of chromosomic analysis showed that the chromosome of Beijing Fatty Chicken, Langshan Chicken and Small-tailed Han Sheep were mainly diploid and the individuals of diploid occupied 87.1%, 86.7%, 93.4% in population observed respectively. The chromosomic structure mutation was 1.5%, 0.8%, 1.4% respectively that different from chromosomic morpHology results reported by other researchers.

染色体分析结果表明，北京油鸡、狼山鸡、小尾寒羊成纤维细胞均以二倍体为主，二倍体染色体数目分别占所观察数目的87.1％、86.7％和93.4％；染色体结构变异率分别为1.5％、0.8％和1.4％；染色体形态与前人报道的其他品种相比略有不同。

Cognition disturbance and allolalia were the chief clinical manifestations. The imageology showed that the impairment involved occipital lobe and temporal lobe most. 17 cases presented red-ragged-fibres and parking lot-like ultrastructure in 3 cases. Brain biopsy showed layerage structure. There were 15 of them carried mtDNA A3243G mutation. Conclusions MELAS Syndrome usually involved central nerve system and skeletal muscle.

主要临床表现为认知功能障碍及言语障碍，头颅影像学检查示枕叶、颞叶脑回受累为主。18例行肌肉病理检查显示17例存在破碎样红纤维，3例行肌肉电镜检查发现线粒体堆积呈停车场样排列，3例脑活检示病变皮层组织呈分层样改变，15例发现mtDNA A3243G点突变。

To disease resistance, SP3 (from H1) had stronger ability to resist leaf mold. 4.The characters obtained by space mutation were easier to be stable. The results showed that, the differences of the flowering dates of 1st inflorescence, the positions of 1st inflorescence, number of leaves between 1st and 2nd inflorescences in the colony were decreased with the development of generations. Most of these heritable characters could be stable in SP3 and a few could be stable in SP4, 2~3 generations earlier than that of traditional breeding (The characters were stable in 6 generations.).

试验结果表明，植株的第一花序开花期、植株的第一花序节位、第一至第二花序间隔叶数及产量的株间变异（变幅、标准差和变异系数），随着世代的递增而降低，大部分株系的变异性状从SP3后就稳定遗传，少数株系的变异性状从SP4后才稳定遗传，比一般常规育种的6个世代开始稳定，可提早2～3个世代，经地面定向选择能较快选出综合性状优良的目标株系。
