The conditions for the reaction of ENA with FDNB was reported, and the relation between the degree of degradation of the RNA and the amount of DNP group combined was studied.The combining site of DNP-in S-RNA was studied by means of ultraviolet absorption spectra, and degradation by RNase and snake venom phosphodiesterase. The results suggested that DNP group combined only with the phosphomonoester of the terminal 5'-phospho guanosine of S-RNA.The possibilities of using the amount of DNP-combined for the calculation of chain length and molecular weight of S-RNA and using the DNP-as a label for the pG……terminal of S-RNA to facilitate the nucleotide sequence analysis from that end are suggested.

(一)本工作报告了FDNB与RNA的作用条件,并研究了不同断裂程度的RNA和FDNB的反应。(二)对DNP-在大肠杆菌S-RNA分子中的结合位置通过紫外线吸收光谱和牛胰RNase以及蛇毒磷酸双酯酶的降解作用做了探讨,由实验结果推断:DNP-似结合在S-RNA末端5′-G核苷酸的磷酸单酯上。(三)本文说明DNP-的结合量可以用来计算S-RNA的链长及分子量;也可以利用DNP-标记pG末端,以便利于该末端核苷酸排列顺序的研究。

Based upon the characteristic reaction of S-RNA with FDNB which resulted in the attachment of the DNP-group only on the 5'-phosphomonoester end group of S-RNA, this report described experiments which utilized the DNP-group as label for the identification of the terminal nucleotides and their adjacent nucleotide sequences.Both the labeled (DNP-S-RNA) and the ordinary S-RNA were digested with pancreatic ribonuclease, and the resulting products were separated by Rushizky and Knight's paper electrophoresis-chromatography mapping procedure. The substances in the major spots of the map so obtained were identified and estimated by spectrophotometry after elution. Results showed no significant differences in the electrophoretic and chromatographic behaviours between DNP-S-RNA and S-RNA. The terminal oligonucleotides labeled with DNP-group (DNP-oligonucleotides) overlapped with the correspondent oligonucleotides on the map. Identification of the DNP of ultraviolet absorption spots were made by spectrophotometry at 350-370mμ after degradation of the eluate with alkali. The results showed that the terminal nucleotides of 5'-phosphomonoester of E. coli S-RNA were pGp···, pAp···pCp···and trace amounts of pUp···.The sequence adjacent to the pXp seemed to differ for different specific S-RNA. Some of them were found to be pGpUp···, pGpCp···, (pGpAp) Op···, (pGpGpAp) Up···,pApCp···, pApUp··· and pGpGpUp··· and/or(pGpAp) Up···.The oligonucleotides consisting of 4 or more nucleotides were not determined.DNP was left in the original spot of the map, indicating the presence of terminal fragments probably made up of more than four purine nucleotides, and analyses of the spot showed that guanylic acid dominated.

(1)比较了E.coli DNP-S-RNA和S-RNA的紫外光谱,并研究了DNP-S-RNA的RNase I的降解条件,结果表明两者无显著差别。(2)对DNP-S-RNA的RNase I降解产物的双向电泳层析图谱进行了分析,并与S-RNA图谱进行了比较,两者图谱中光吸收点的分布一致,相应点经洗脱后,由光谱分析与核碱组成测定证明均含有相同的核苷酸组成。(3)在DNP-S-RNA和S-RNA于同一条件下得到的图谱中,前者的某些光吸收点中含有不同量的DNP-。根据DNP-可以标记S-RNA末端5′-磷酸单酯,分析了DNP-结合物,说明在E.coli S-RNA分子中,B末端核苷酸除pGp…以外,尚有pAp…,pCp…以及痕量的pUp…。和末端相邻的核苷酸排列形式,随特异S-RNA而有不同,有pGpUp…,pGpCp…,p(GpGpAp)Up…,p(GpAp)Up…+pGpGpUp…,p(GpAp)Cp…,pApUp…和pApCp…。其他四核苷酸以上多核苷酸未分析。由于电泳和层析后原点部分标记了DNP-,估计末端核苷酸排列有五、六核苷酸以上的多嘌呤核苷酸的排列形式,其中以G为主。

The best preserved portions of the muscle tissues of the wife of Li-tsang, the Marquis of Tai and Chancellor of the Kingdom of Changsha, retained distinct contours and showed characteristic cross-striations. Under the electron microscope, one could see clearly substances of the A band and the Z band, whereas those of the H zone and the I band disappeared almost completely. The muscle fibril assumed the shape of a bamboo shoot, looking as if it were made up of a stack of alternate layers of two "half A disks"...

The best preserved portions of the muscle tissues of the wife of Li-tsang, the Marquis of Tai and Chancellor of the Kingdom of Changsha, retained distinct contours and showed characteristic cross-striations. Under the electron microscope, one could see clearly substances of the A band and the Z band, whereas those of the H zone and the I band disappeared almost completely. The muscle fibril assumed the shape of a bamboo shoot, looking as if it were made up of a stack of alternate layers of two "half A disks" (one wing of the A cylinder minus the H zone) to one Z disk, held together by remnants of the microfilaments and wrapped up in the sarcoplasmic reticulum. Using subtilisin digestion and mechanical disintegration we were able to obtain fragments of the Han cadaver resembling the following constituents of the myofibril: "half A disk" and its fragments, thick and thin filaments with a length equal to the thickness of the "half A disk", and Z disk and its fragments.Taking into consideration the relative emptiness of the I band on both sides of the Z disk as well as of the H zone of the A band, and the relative accessibility of sarcoplasmic enzymes to the I and H bands of human myofibril, we have carried out a model experiment in an attempt to simulate the limited autolysis of the muscle of the Han cadaver. It was found that when fresh human muscle was treated with an excess of a crude preparation of beef spleen cathepsins, one could obtain electron micrographs strikingly similar to those obtained in the case of the Han cadaver. The results throw some light on the possible role played by cathepsins in the limited autolysis of the Han cadaver.Using the sandwich, indirect immunofluorescence technique, with fluorescein isothiocyanate as the label, it was shown that the best preserved portions of the psoas muscle of the Han cadaver retained antigenicity to a certain extent.It was possible to solubilize some proteinous constituents of the muscle with the aid of S. D S., urea, ethanolamine and other solvents.A. considerable proportion of the collagenous constituents of muscle tissues of the Han cadaver was found to be fragmented into 20~40 A miorofilaments in 1.5% S.D. S. solution at pH 7, a phenamenon closely parallel to that shown by fresh human collagen. Clostridium collagenase acted upon the collagenous fibrils and gave rise in succession to loss of contrast, disappearance of cross-striations and fragmentation into microfilaments, in a manner analogous to that exhibited by controls.Detection of cytochrome c in the heart muscle and pancreatic enzymes in the pancreas gave negative results. It was possible, however, to isolate some proteinous fragments from the brain tissue.Aspects of the preservation of the Han cadaver, such as the exogenous and endogenous factors for preservation, in vitro and in vivo stability of the protein molecules concerned, and rapid and long term changes suffered in the course of time, were discussed in the light of experimental findings.
