Crystalline needles and spindles of tropomyosins from the smooth muscles of pig stomach, pig urinary bladder, duck and goose gizzard, the striated muscle of crab (Eriocheir sinensis M. Edw.) and the adductor and foot muscles of bivalves (Anodonta pacifica Heude) and of paramyosins from the two last-mentioned muscles were examined under a HU-11 electron microscope. The samples were either stained with phosphotungstic acid or shadow-casted with Pt or Pt-Ir. All of these showed distinct cross striations. The banded structure and the appearance of the tapering ends suggested that they were ordered, one-dimensional paracrystalline arrays, not true crystals with threedimensional regularity.The paracrystals of the tropomyosins investigated were all endowed with cross striations with a fundamental repeat period of n×200A, where n=1,2. The 400A period may or may not be accompanied by an intermediate line. These spacings were identical with those of the open-network lattice observed in true crystals of rabbit tropomyosin.The patterns of paracrystals of duck or goose gizzard deserved special attention. In addition to the 400 A and 200 A periods or intraperiod spacings, a prominent 800A (n=4) period was often observed. It seemed not unlikely that 800A corresponded to the particle length of this tropomyosin. Shadow-casted specimens of paracrystals of Anodanta adductor tropomyosin also revealed axial periods of about 800 A.The patterns of the paracrystals of paramyosins obtained from the foot and adductor muscles of Anodonta resembled closely those obtained from the adductor muscles of its marine relatives reported in literature. There were 4 equally-spaced intraperiod lines in a period of about 700 A, the spacing of these lines being 140 A.Obtained in the presence of high salt concentrations, the paracrystalline arrays of the tropomyosins from the adductor and foot muscles of Anodonta differed significantly and interestingly from those obtained conventionally in the presence of low salt concentrations. Although the fundamental repeat of about 400 A remained the same, the intraperiod fine spacings changed now from the 200 A characteristic of tropomyosin to the 140 A characteristic of paramyosin.On the basis of electron microscopic periodicities, it was tentatively suggested that tropomyosin and paramyosin were two different kinds. of proteins. Nevertheless, when they co-existed in one and the same muscle, such as the adductor or foot muscle of Anodonta, the existence of some genetic relationship between the two may have to be reckoned with.

The influences of heat setting conditions on the structure of PAC fibres investigated from several approaches like thermal swelling retractions,X-ray diffraction and studies of mechanical properties.The as-spun fibres were dried,heat set in dry state,steam-set relaxed,hot drown once more,and steam-set relaxed again.Each heat setting treatment left a mark on the structure of the fibre.For instance,hot drawing would impair the order,cause internal stresses to occur within certain maoromolecular segments and pro-duce...

The influences of heat setting conditions on the structure of PAC fibres investigated from several approaches like thermal swelling retractions,X-ray diffraction and studies of mechanical properties.The as-spun fibres were dried,heat set in dry state,steam-set relaxed,hot drown once more,and steam-set relaxed again.Each heat setting treatment left a mark on the structure of the fibre.For instance,hot drawing would impair the order,cause internal stresses to occur within certain maoromolecular segments and pro-duce defects and distorsions in the paracrystalline structure;the effects of steam setting,however,would go just by contraries.In conjunction with the studies of mechanical properties,it was discovered that the primary factor which influenced the loop strength of the fibre was the breaking extension,while the perfection of crystallization in the paracrystalline region was secondary.

本文从热溶胀收缩,X-光衍射和机械性质几个方面,观察热处理条件对丙烯腈三元共聚纤维(PAC纤维)聚集态结构的影响.成形后的纤维经过干燥、干热定型、松弛汽蒸定型、再次热拉伸和再次松弛汽蒸定型,每一次热处理都在纤维的聚集态结构上留下印记.拉伸会降低序态,在无定形区的某些大分子链段中产生内应力,在蕴晶区造成结晶缺陷;汽蒸定型的作用则刚巧相反.联系纤维的机械性质,发现决定纤维钩强的主要因素是纤维的断裂伸长,蕴晶区的完整程度是次要的.

The structure of collagen fibers in the loose and dense connective tissues, from various sources (central tendon of dog diaphragm, tentorium cerebelli of hen, pericardium of adult man, etc.) were investigated with light microscope (LM), transmitting electron microscope (TEM) with ultra thin sections cut after reembedding with epoxy resin following orientation under LM, and ultrathin section under TEM coordinated with the semithin section under LM. It was observed that: (1) The logitudinal striated structure within the so called collagen fibers and the collagen fiber without the logitudinal striated structure under LM are all the closely arranged collagen fibril bundle in which the space between the fibrils is narrower than 0.2μm under TEM. So that both must belong to the same grade. (2) The collagen fibrils in vivo may be singlely dispersed, or in double, or in bundles formed from 3 to hundreds of fibrils; the space between fibrils varied closely to several μm. (3) The diameter of collagen fibrils is genera ly 20—200 nm, but there are also thicker or thiner fibrils. According to these and other previous works, we suggest the following points on the nomenclature: (1) The collagen fibril is the collagen structure which has generally the diameter of 20—200nm and the cross striations of 64—70nm along its longitudinal axis under EM It should no longer be Called the collagen microfibril. (2) The collagen fiber is the bundle which is composed of three or more closely arranging collagen fibrils bound by a small amount of cement substance. Under EM, the space between the bundles is larger than 0.2μm but the space between the fibrils within the bundle is narrower than 0.2μm. Under LM, the collagen fiber is the structure without the visible subunit filament and may branch and anastomose- each other. (3) The collection of collagen fibers should be called collagen fiber bundle. It includes the so called "collagen fibers" (old routine nomenclature) with the visible subunit filaments under LM. This nomenclature should remove the confusion on the structural grading of collagen fibers and unify the concept of collagen fiber under LM with that under EM.

通过光镜观察、光镜观察定位重包埋电镜观察、电镜观察加半薄切片光镜定位法,对疏松和致密结缔组织、一些特殊部位材料(狗横膈中心腱、鸡小脑幕、成人心包膜)及5个月胎儿、新生儿一些组织中的胶原纤维结构,进行了观察研究。 (1) 光镜下胶原纤维中的纵纹样细丝,在电镜下观察是排列紧密的胶原原纤维束,束内原纤维间的距离小于0.2μm;而光镜下看不见细丝的胶原纤维,在电镜下也是间隙小于0.2μm的胶原原纤维束,二者属同一级别。(2) 胶原原纤维在体内的存在方式,可以单根散在、两根并存或由数根,乃至数百根集合成粗细不等的束;原纤维间或紧密相贴,或相距若干微米不等。(3) 胶原原纤维直径一般在20~200nm之间,但不排除大于或小于此直径的原纤维存在。本文还对胶原纤维有关命名提出建议:(1) 电镜下直径在20~200nm之间,并具64~70nm周期横纹的胶原结构,称为胶原原纤维。(2) 3根以上密集排列的胶原原纤维,借少量粘合质粘合成的束,称为胶原纤维。电镜下束间距离大于0.2μm,而束内原纤维间的距离小于0.2μm。光镜下胶原纤维是看不到更细的细丝的结构,并可分支吻合。(3) 胶原纤维聚集成方向基本一致的束样结构,...
