又一种引致人体原发性皮肤毛霉病的非商温根毛霉属真菌

一年多以前,我们报道了一种引致人类原发性皮肤毛霉病的病原真菌Rm6并定名为多变根毛霉((Rhizomucor variabilis Zheng & G.-q. Chen)。最近我们又发现了它的另外一个变种Rm7。它是北京医科大学第一医院的王端礼教授分离的,原编菌号4873。Rm7的病人和Rm6的情况很相近。她也是一个女病人,来自农村,患的同样是原发性皮肤病而没有患有其他的毛霉病或其他疾病,她的病也没有传染给她的家人。不同的是,她来自我国北部的河北省而不是南部的江苏省;她的病史更长,达16年之久;她的病部在脸上而不是在手上,并造成进食困难。Rm7和Rm6的培养物相似,也是亮黄色,但比较低矮。它与Rm6一样是非高温真菌,最适、最高、最低温度同样分别是24-30, 38,和9℃形态上的亲缘性也是显而易见的:两者都有匍匐菌丝和较发达的假根;孢子枝也是假轴分枝;孢子囊壁也是缓慢消解;有很不规则形状的囊轴;有明显的囊领;都有大量厚垣孢子。Rm7与Rm6的主要区别在于:(1)假根只从匍匐菌丝和气生菌丝上长出而不从孢子枝、孢子囊或囊轴等各处长出;(2)孢子枝可连续分枝达7次之多;(3)孢子枝在分枝处往往有一个隔膜;(4)往往在10天以上的培养物中才出现不规则形状的囊轴;(5)从未见有囊托;(6)孢囊孢子形状较规则,较短而不超过11 μm;(7)孢子囊和囊轴均较小,直径相应不超过70及30 μm.因此,我们将Rm7鉴定为Rm6的一个变种,并定名为较规则多变根毛霉新变种(Rhizomucor variabilis var. regularior Zheng & G.-q. Chen var.nov.)。这样,在根毛霉属内可以承认的共计5种6分类群。     

Fine structure of the homologous tergo-coxal muscles of flying and flightless beetles

The flight-related tergo-coxal muscles of flying and flightless beetles are compared. In the flying beetle, Pachynoda sinuata, the myofibrils and cylindrical and the myofilaments packed in double hexagonal arrays. The sarcomeres are short (2.8 micrometer) and wide with many large, closely packed adjacent mitochondria but the sarcoplasmic reticulum is poorly developed in this fibrillar (asynchronous) muscle. Sarcoplasmic glycogen in rosette form is abundant. In the flightless beetle, Anthia thoracica, the myofibrils are lamellar-like with sarcomeres of 5.3 micrometer. The myosin filaments form a single hexagonal array each thick filament having an orbital of 11 to 12 thin filaments. The width of the Z-line (120 nm) of A. thoracia muscle was twice that of the Z-line of P. sinuata muscle. The sarcoplasmic reticulum and T-system are well-developed in this afibrillar (synchronous) muscle. Few glycogen granules are present. Triangular projections of the sarcolemma occur regularly opposite the Z-lines in A. thoracica and they appear to extend into the Z-lines. Membranous connections joint adjacent Z-lines in A. thoracica and occasionally in P. sinuata.

Primary structures of neuropeptides isolated from the corpora cardiaca of various cetonid beetle species determined by pulsed-liquid phase sequencing and tandem fast atom bombardment mass spectrometry.

A peptide with the same retention time on gradient reversed-phase high-performance liquid chromatography was present in the corpora cardiaca of 5 scarabaeid beetles, subfamily Cetoniinae: the three fruit beetle species Pachnoda marginata, P. sinuata and P. aemulae and the two protea beetle species Trichostetha fascularis and T. albopicta. Crude corpora cardiaca material from P. sinuata had a small hypertrehalosaemic effect in American cockroaches and a very weak hyperlipaemic activity in migratory locusts. Injections into P. sinuata caused hypertrehalosaemia when a dose of 1.0 corpora cardiaca equivalents was injected. An identical neuropeptide was isolated, by RP-HPLC, and sequenced by pulsed-liquid phase sequencing employing Edman chemistry after enzymically deblocking the N-terminal 5-oxopyrrolidine-2-carboxylic acid residue, as well as by collision-induced decomposition tandem fast atom bombardment mass spectrometry. The peptide is a blocked octapeptide: Glu-Leu-Asn-Tyr-Ser-Pro-Asp-TrpNH2, previously designated Mem-CC. The synthetic peptide is able to elicit haemolymph carbohydrates in P. sinuata upon injection of low doses. Activity studies using synthetic analogues of this peptide revealed that Tyr4 may be important for receptor recognition/binding. The peptide is synthesized in intrinsic cells of the corpus cardiacum as shown by in vitro incorporation of [3H]Trp and [14C]Tyr in Mem-CC.
