It decreased with the advance of age, being 98.1% in the newborn below the age of 2 months; 70.2% at the age of from 2 months to 1 year; 55.0-57.1% at the age of 1-5 years; 21.7% above 5 years.

Postmortem examination of the hearts of 500 Chinese with age ranging from new born to 70, revealed defects in the interatrial septum in the form of cleft, hole or short canal in 51% of the cases. It decreased with the advance of age, being 98.1% in the newborn below the age of 2 months; 70.2% at the age of from 2 months to 1 year; 55.0-57.1% at the age of 1-5 years; 21.7% above 5 years. The closure seems to start from the age of 2 months and ends at the age of 5 years. There exists a slight difference between the male and female bodies examined, the defect being found in 59.2% of the female and 46% of the male. The clinical significance of such openings was discussed.

Consideration on various grounds has led to the inclusion of three new species ofladybeetles in the Coccinellidae fascicle of the Economic Series of the Chinese InsectFauna, now going to the press. To make available the species names proposed and tofacilitate future reference, new species descriptions are herewith published in advance inthis journal. In the course of the present study, the external genitalia of both the male andfemale sex have proved, as of wont, exceedingly helpful in species discrimination. Es-pecially worth mentioning is a hitherto neglected structure--the basal "handle"-like por-tion of the genital plate or the "Stiel" in Verhoeff's terminology, which has shown pos-sibilities of being more widely made use of in future investigations of Coccinellid taxo-nomy. It first attracted attention in the comparative study of the female genital platesof Coccinella undecimpunctata and C. geminopunctata(a new species to be describedpresently), two forms closely resembling each other in point of elytral pattern but differ-ing widely if genitalia are taken into account. This basal portion of the genital plateof C. 11-punctata is short and bluntly rounded at the end, whereas that of C. gemino-punctata is long and crenate at the corresponding point. Again in the three species ofBallia studied, B. obscurosignata sp. n. has a hooked end, while in B. korschefskyi andB. didnae, the end is branched though in quite different manners (fig. 3, A & B). Forthe sake of easier reference, the term capulus (Lat., a handle) has been proposed. The three new species described in this paper are: Coccinella geminopunctata, C.longifasciata and Ballia obscurosignata. Coccinella geminopunctata resembles closely C. undecimpunctata in having an identicalnumber of black spots (11 altogether) and in their general disposition on the elytra, butmay be readily distinguished by its two apical spots being at one level in contrast to thefore-and-aft placement in the Linnaean species. Their genitalia are evidently of verydifferent types. The penis in the new species has a wedge-shaped cleft at about themiddle on each side, while the 11-punctata penis has the sides entire. But the greatestdifference is shown in the capulus as discussed in the paragraph immediately preceding.In point of general form of the penis, C. geminopunctata shows similarity to C. trans-versoguttata, a species with totally different elytral pattern. The new species can more-over be distinguished at sight by its larger body size. Coccinella longifasciata distinguishes itself by having a longitudinal black stripe onthe elytral disc, besides one on the suture. The elytral stripe, by virtue of its obliqueposition, offers a clue to its having possibly been derived from the basic pattern ofDobzhansky (1926) (fig.4), with the extension and confluence of spots 1, 3, 5 and theoblitration of the two lateral spots. So far as the writer is aware, this type of patternis quite rare, if not unique, in the genus Coccinella. In the male genitalia structures, C.longifasciata shows some resemblance to C. trifasciata in the shape of the penis but differsin having the basal portion narrowed, whereas in the other it is wide throughout. It isalso obvious that the coalescence of the spots is longitudinal in one and transverse in theother. Ballia obscurosignata is characterized by the peculiarity shown in the indistinctnessof the white-colored pattern, which, moreover, is quite variable. The genitalia conformto the type of the genus but in the capulus it shows an individuality not approached bythe two congenric species (B. korschefskyi and dianae) currently investigated. This specieswas found on pine trees both in the north and the south, and is evidently an aphidfeeder. As an adjunct to this study and a continuation of a previous effort (Liu, 1950),proposals have been advanced to revise and supplement the Chinese terminology of thegenitalia structures of the Coccinellidae.

由于不同的原因,弯斑瓢虫(Coccinella geminopunctata),纵条瓢虫(C.longifasciata)和隐斑瓢虫(Ballia obscurosignata)三个新种被认为应当包括在即将付印的《中国经济昆虫志:瓢虫科》一书中。为了便于使用新种的学名,更为便于日后的查考,特先在学报发表该三种的记述。 就如在其他分类工作中一样,雌雄两性的外生殖器对种的辨识起了很大作用。在这次工作中,发现雌瓢虫的生殖片基部柄形部分在各种中有相当的差异,可能发展为有用的特征,因此命名为“基柄”(ca-pulus)。 继1950年的尝试,本文对瓢虫外生殖器的汉文名词做了一次增补与修订。

The present study is undertaken to compare the physico-chemical properties of foetal AFP and cancerous AFP of the liver purified by immunoadsorbent column with antibody specific to human AFP. For the AFP's from these two sources, it is found that the U. V. absorption maxima occured at 278 nm, their extinction coefficients, E_(1cm)~(1%), were 5.20±0.06 and their molecular weights, 71000. Two AFP fractions are observed in isoelectric focusing with pI's at 4.7 and 5.25±0.05. At 75.5℃ the kinetic constants of thermal...

The present study is undertaken to compare the physico-chemical properties of foetal AFP and cancerous AFP of the liver purified by immunoadsorbent column with antibody specific to human AFP. For the AFP's from these two sources, it is found that the U. V. absorption maxima occured at 278 nm, their extinction coefficients, E_(1cm)~(1%), were 5.20±0.06 and their molecular weights, 71000. Two AFP fractions are observed in isoelectric focusing with pI's at 4.7 and 5.25±0.05. At 75.5℃ the kinetic constants of thermal in activation for immunochemical activity are as follows: the rate constant of inactivation (k) 7.29×10~(-5) sec~(-1), the free energy of activation (E~+) 95.4 KCal·Mole~(-1), the enthalpy of activation (△H~+) 94.7 K Cal·Mole~(-1), and the entropy of activation (△S~≠) 193 Cal·Mole~(-1). Degree~(-1). From evidence furnished by SDS-polyacrylamide electrophoresis it appears most likely that both foetal AFP and cancerous AFP consist of single polypeptide chains. Their amino acid compositions are very much alike and their S-S bonds play a very important role in maintaining the immunochemical activity of AFP. Both GNBr-cleft AFP samples give 7 main peptide-fragments and corresponding peptides have closely similar molecular weights. From the above mentioned results it may be concluded that no differences in the nature of these two AFP's have been observed.

本文比较了胎儿AFP和肝癌AFP的物理化学性质,所测指标未发现本质差异。实验测得紫外吸收峰在278毫微米,消光系数E_(1厘米)~(1%)5.20±0.06。分子量71000左右。等电聚焦观察到AFP至少有两种形式,pI值分别为4.7和5.25±0.05。75.5℃热失活动力学参数:失活速度常数k7.29x10~(-5)秒~(-1),活化能E~≠95.4千卡/克分子,活化热焓ΔH~≠94.7千卡/克分子,活化自由能ΔF~≠27.2千卡/克分子,活化熵ΔS~≠193卡/度·克分子。分子量为71000的AFP分子可能由一条多肽链组成,二硫键对维持其免疫化学活性起重要作用,溴化氰裂解可得到分子量不等的七个多肽片段。
