犏牛雄性不育的多基因遗传不平衡假说

根据犏牛雄性不育的研究结果，提出了犏牛雄性不育的多基因遗传不平衡假说．假说认为，不育性是受多基因控制的，牦牛和普通牛由于在多个基因位点上的遗传差异而使犏牛的基因平衡失调，导致不育．最后对该假说的部分证据进行了讨论和分析     

Cornelius Lanczos’s Derivation of the Usual Action Integral of Classical Electrodynamics

The usual action integral of classical electrodynamics is derived starting from Lanczos’s electrodynamics – a pure field theory in which charged particles are identified with singularities of the homogeneous Maxwell’s equations interpreted as a generalization of the Cauchy–Riemann regularity conditions from complex to biquaternion functions of four complex variables. It is shown that contrary to the usual theory based on the inhomogeneous Maxwell’s equations, in which charged particles are identified with the sources, there is no divergence in the self-interaction so that the mass is finite, and that the only approximations made in the derivation are the usual conditions required for the internal consistency of classical electrodynamics. Moreover, it is found that the radius of the boundary surface enclosing a singularity interpreted as an electron is on the same order as that of the hypothetical “bag” confining the quarks in a hadron, so that Lanczos’s electrodynamics is engaging the reconsideration of many fundamental concepts related to the nature of elementary particles.     

葡萄胎曾患者家族癌症史研究

对１９８０～１９８１年间先后两次在广西灵山、钦州及扶绥县农村进行葡萄胎发病调查中获得的１４１例曾患者家族癌症史有关资料及１９８３年就葡萄胎曾患者家族癌症史问题在南宁市及其近郊进行的１１２例专题调查作综合研究。各项调查均同时在每例曾患者的同村庄，同街道，或同一工作单位随机选取１～２例年龄、胎次相当，且无自发流产或死胎史的曾孕妇女作为对照。结果表明，各组曾患者家族癌症史阳性率均高于对照组，以南宁组者为最高，达２１．８％（２２／１０１）；其中又以一级亲属所占的比例最高，与对照组相比，差异性显著（Ｐ＜０．０５）；调查涉及的癌，大多属多基因（或多因子）遗传癌。提出，葡萄胎可能有多基因（或多因子）遗传基础，且与其他多种癌有一部分共同的发病因素。对葡萄胎家族聚集性不明显的可能原因进了简短讨论。
