It was a new mousegene in GenBank and named as SRG-L(spermatogenesis related gene expressed in the latestages of spermatogenic cells). The sequence of this cDNA has been deposited in GenBankwith the Accession No. AY352586. 2. Analyses of expression characteristics of SRG-L during mouse spermatogenesis.The results of RT-PCR and Northern Blotting indicated that no expression signal of thisgene could be observed in primitive type A spermatogonia and type B spermatogonia. Asignal first appeared in diplotene/pachytene spermatocytes, and was significantlyintensified in round spermatids and elongating spermatids, findly went down to beundetectable in mature spermatozoa.

RT-PCR和Northern Blotting分析表明：该基因在早期A型和B型精原细胞中不表达，从双线期初级精母细胞阶段开始表达并逐渐上调，在粗线期初级精母细胞、圆形精子细胞及长形精子细胞中均检测到高水平的mRNA，但在成熟精子中消失，具有明显的阶段特异性表达特征，并且组织特异性表达分析显示该基因在睾丸组织中的呈高表达。

Bnormal MRI manifestations in all of the 20 cases with acquired hepatocerebral degeneration,in which T1WI demonstrated increased signal in hibateral lentiform nucleus (n=20),globus pallidus(n=17),surrounding mesencephalon red nucleus(n=15),and in anterior pituitary(n=4)While T2WI demonstrated no corresponding alteration in signal intensityConclusion Abnormal MR signal in the patients with acquired hepatocerebral degeneration has special features and MRI has right value for the diagnosis of this disease

全部病例均有完备的临床与MRI资料。结果：20例脑部均有阳性MRI表现，其中双侧、豆状核20例，苍白球17例，中脑红核周围15例，垂体前叶4例，表现为自旋回波序列T1WI为高信号，T2WI及FLAIR像无异常。结论：获得性肝性脑部变性的MRI征象具有特征性，MRI对该病的诊断有较高价值。

At the chapters of theory analysis,constitutive equation of dusty is deduced from the results of the experiment and related theories about oblique shock wave.after that relationship of parameters reflecting flow-field characteristic are deduced from theories of shock wave polar .The paper set up conservation equations depicting gas and solid flow-field by double fluid model,thus equations and constitutive equation of granular phase form closed equations.then the paper uses AUSNT vector splitting method to numerically calculate the equations.
