Earlier epidemiologic research had demonstrated that young men who had been exposed to in utero ultrasonic scans are more apt than other young men to be left-handed; there is a correlation between left-handedness and reduced intellectual capacity in children born after a difficult pregnancy.

较早期的流行病学调查已经证实，曾经暴露于子宫超声扫描的年轻男性，比其它男性更加容易出现左撇子；在左撇子倾向与难产儿童智力下降之间有相关性。

Leishmania promastigotes antigens have good stability and heat-resistant nature. The sensitivity of 901 and 801 antigen were better, so we thought it could be used for serologic epidemiology investigation in XinJiang.

利什曼原虫前鞭毛体抗原有较好的稳定性，耐热性极好；901株、801株抗原的敏感性、特异性较好，可做为新疆血清流行病学调查所用的抗原株；801株的特异性更好，可用于黑热病的特异性抗体的检测及研究。

To explore the influence of reticuloendotheliosis virus and subgroup J avian leucosis virus infection on chicken cellular immunity,the mitogenic response to ConA of blood and spleen lymphocytes tested and analyzed with 3H-thymidine(3H-TdR) incorporation assay at different intervals after infection or co-infection of single or both viruses.

自1974年分离出网状内皮增生症病毒[1]和1991年分离出禽白血病病毒J亚群[2]以来，在我国先后分离出不同毒株的REV和ALV-J，并开展了病原学、流行病学、致病性和免疫反应以及预防诊断等方面的研究，揭示出不同的致病性，并且确认它们都可造成感染鸡群免疫抑制，成为一些

The former hypothesis is mainly based on mathematical linear extrapolation from effects observed by high doses. This notion advocates the linear assumption of radiation risk and that there is no lower limit to the amount of radiation that causes short- or long-term damage. The latter is the countervailing hypothesis-radiation hormesis.

前者主要依据高辐射剂量效应的观察，用数学线性补插法来求低剂量之效应，主张：辐射剂量会造成短或长期的伤害，且无低限值的；后者的证明来自於广泛的流行病学观察和实验研究的科学资料，这些证明指出辐射对人的伤害有确定的阀值剂量。
