The immunostianing of ghrelin was not observed in Leydig cells after the impairment. Conclusion The changes in the expression of ghrelin suggest that ghrelin may play an important role in the function regulation of testis and the process of spermatogenesis and spermiogenesis.

结论Ghrelin在小鼠正常及辐射损伤睾丸中的特异性表达和变化，提示其可能与睾丸精子发生、精子形成及辐射损伤修复有关，具有重要的睾丸生物学调节功能。

In order to clear the aphid and Citrus tristeza disease epidemiology, in this research, to determine the dominant stocks of aphid on citrus by investgatting the occurrence and the damage of the aphids; to clear the relation of aphids and citrus tristeza disease epidemic by analysissing the identity and the efficiency of T.

为了解蚜虫与CTV流行的关系，本试验通过调查柑桔蚜虫的发生与为害，明确柑桔蚜虫的优势种群；就橘蚜传播柑桔衰退病的传毒特性、传毒率、影响传毒率因素等的分析，明确蚜虫在柑桔衰退病流行中的作用；以及对带毒橘蚜体内的CTV分子生物学检测。

Two mode of plastid inheritance, uniparental maternal and biparental inheritance, were discovered in angiosperms at the beginning of this contury, and our knowledge of the mode and cytological basis of cytoplasmic inheritance, esp. plastid, has been improved in many respects following the new cytological and molecular techniques, eg. electron microscopy, DNA fluorescence and RFLP.

近几年由于电镜、DNA的荧光检测及RFLP等新的细胞学和分子生物学技术的发展，使对植物细胞质遗传形式及其细胞学基础有了一定的了解，但多是单一的方法或对雌、雄配子发生、发育个别发育时期研究的结果，对大部分植物种的质体遗传方式或细胞学基础仍不清楚，在有些植物种间应用不同的研究方法得出的结论也不一致。

Cardiac hypertrophy is one of adaptive responses of the heart to a variety of pathological stimuli, including hypertension, myocardial infarction, congenital heart disease, heart valvula disease, and perturbations in sarcomeric function due to altered expression or mutations of contractile proteins. Increase in wall tension and hormonal stimuli are thought to directly activate various membrane-bound receptors and signal transduction cascade within cardiomyocytes resulting in the activation of immediate early genes and responsive genes such as c-jun, c-fos, c-myc, egr-1, ANF, BNP. Then the expression of construction proteins such as MLC-1, skeletal α-actin was unregulated.

Professor Wootton says biological factors were missing from previous models of ocean climate systems - and that life in the ocean, or in this case on the ocean edge, can also affect seawater pH.

伍顿教授称，生物学的因素和海洋中的生命都比以前海洋气候系统模型中的少，如果这种情况发生在海边，也会影响海水的PH值。
