中药异位康冲剂治疗子宫内膜异位症小鼠的研究

目的：探讨中药异位康冲剂对小鼠子宫内膜异位症的作用及可能机理。方法：通过对小鼠一般情况、血常规、肝肾功及各主要脏器的组织学观察,观察中药异位康冲剂急性和长期毒副作用。通过一般情况、阴道脱落细胞观察、激素检测、病理组织学检查及血液流变学的改变,了解中药异位康冲剂对小鼠子宫内膜异位症模型的药理作用。结果：急性和长期毒性实验表明,中药异位康冲剂无明显毒性反应。异位康冲剂能抑制大鼠子宫内膜异位模型,降低血清雌二醇水平（P〈0.01）。病理学观察显示异位子宫的内膜腺体及腺上皮明显萎缩,其作用与丹那唑相似。结论：中药异位康冲剂无明显毒副作用,可促进子宫内膜异位组织细胞凋亡、抑制子宫内膜异位组织增殖,为临床用药提供了实验依据。     

1164例围绝经期阴道不规则出血的临床及病理结果分析

目的：探讨围绝经期妇女不规则阴道出血的临床和病理特点。方法：对1164例40~55岁阴道不规则出血的妇女的临床和病理资料进行回顾性分析。结果：发生绝经期阴道不规则出血者正常子宫内膜占32．22％,粘液和萎缩性内膜占2．06％,慢性子宫内膜炎占3．18％,子宫内膜良性病变占61．42％,恶性肿瘤占1．12％。慢性子宫内膜炎的发生与年龄有关（P〈0．05）,而粘液及萎缩性子宫内膜、子宫内膜良性病变和恶性肿瘤与年龄无关（P〉0．05）。结论：围绝经期阴道不规则出血主要是由卵巢功能低下内分泌功能紊乱引起,以正常子宫内膜和良性病变为主,及时诊断和治疗可明显降低恶性肿瘤的发生率。

子宫异常出血与细菌L型感染的关系

通常认为,子宫异常出血由内分泌紊乱、内膜肿瘤和子宫内膜炎引起。通过对471例子宫异常出血内膜组织的细菌学及免疫组化等研究,我们发现绝大多数(85.7％)出血者原因不明,其中376例子宫内膜查见L型菌。本组细菌L型感染率为93.8％。提示子宫异常出血(包括绝经后出血)与细菌L型感染关系也很密切。并认为,子宫内膜细菌L型感染是导致子宫异常出血的重要原因之一。选择作用于细菌胞膜的药物治疗细菌L型感染效果最好。

子宫内膜异位症大鼠模型的建立及其病理学改变

目的构建子宫内膜异位症（内异症）大鼠动物模型,为阐明内异位症发病机理以及寻找有效的治疗方法提供理想的动物模型。方法取性成熟雌性Sprague-Dawley（SD）大鼠30只,通过手术将大鼠自体子宫组织移植到子宫旁韧带上,建立诱发型内异症大鼠动物模型。术后8周,再次剖腹观察异位组织的存活情况、病灶大小、与周围组织的粘连程度以及病理学变化。结果25只大鼠有明显的异位病灶。所有病灶都与周围组织有不同程度的粘连,病灶外观呈囊泡状。光镜观察见大部分异位子宫内膜形态和结构与在位子宫内膜基本相同,但内膜细胞、间质细胞、腺体,与在位内膜相比较少。少数病灶只有上皮组织或只有问质组织。结论自体子宫移植法可成功建立内异症大鼠模型。     

细菌L型感染与慢性子宫内膜炎

本文应用微生物培养、免疫组织化学等方法,对876例子宫内膜进行了组织病理学研究。发现:1.子宫内膜细菌 L 型感染病例中,32.5%的内膜间质有淋巴细胞浸润、淋巴滤泡形成或伴有浆细胞浸润。尚有部分病例虽有感染,但无慢性炎细胞浸润。2.细菌学检查阴性病例,内膜间质无慢性炎细胞浸润。3.病原微生物培养显示70.8%为金黄色葡萄球菌 L 型感染。4.免疫组织化学证明子宫内膜间质细菌型和 L 型的检出率高于腺体。作者提出子宫内膜间质中淋巴细胞浸润或淋巴滤泡形成系细菌 L 型感染的病变特征。故也是慢性子宫内膜炎的诊断依据。

Cause of Senescence of Nine Sorts of Flowers

The levels of endogenous phytohormones and respiratory rate in nine sorts of flowers such as Cymbidium faberi Rolfe, Nopalxochia ackermannii Kunth and others were investigated both at full bloom and senescence and meanwhile the effect of exogenous phytohormones on prolonging the blossoms and promoting ethylene production were tested. There is a high content of endogenous ethylene in all the long-lived flowere, about 3–16 folds higer than the short-lived ones. There is a high level of ABA at full blooming flowers of short-lived flowers, in which there is no or only some cytokinins in it, but the ratio of CTK (6BA+zeatin)/ABA is smaller(l.7). The endogenous ABA reached a much higher level at senescence in all nine sorts of flowers, so it is reasonable to consider that it is ABA which plays an important role of regulation in controlling flower's senescence. There is a much higher level of GA3 and zeatin in the long-lived flowers which is not demonstrated in the shortlived ones. The respiratory rate is one of the factors controtling the longevity of flowers, but it does not play a decided role. Application of 6BA and zeatin prolongs distinctly orchid’s longevity, however exogenous IAA through the promotive action on ethylene production, evidently extends the longevity of the flowers of the Nopalxochia ackermannii Kunth.     

Photoregulation of seed germination of wild-type and of an aurea-mutant of tomato

Seed germination of an aurea mutant of tomato ( Lycopersicon esculentum Mill.) is promoted by continuous irradiation with red, far-red or long-wavelength far-red (758 nm) light as well as by cyclic irradiations (5 min red or 5 min far-red/25 min darkness). Far-red light applied immediately after each red does not change the germination behaviour. Seed germination of the isogenic wild-type, cv. UC-105, is promoted by continuous and cyclic red light while it is inhibited by continuous and cyclic far-red light and by continious 758 nm irradiation. Far-red irradiation reverses almost completely the promoting effect of red light. The promoting effect (in the aurea mutant) and the inhibitory effect (in the wild-type) of continuous far-red light do not show photon fluence rate dependency above 20 nmol m⁻² s⁻¹. It is concluded that phytochrome controls tomato seed germination throgh low energy responses in both the wild type and the au mutant. The promoting effect of continuous and cyclic far-red light in the au mutant can be attributed to a greater sensitivity to P_fr.

The effects of glutamine of the maintenance of embryogenic cultures of Cryptomeria japonica

Summary Embryogenic tissues of sugi (Cryptomeria japonica) were induced on a modified Campbell and Durzan (CD) medium containing 1 μM 2,4-dichlorophenoxyacetic acid (2,4-D) and 600 mg l⁻¹ glutamine, and subcultured in the medium of the same composition for over 1 yr. This resulted in a mixed culture of embryogenic and non-embryogenic cells. When embryogenic cells were isolated and cultured independently, their capacity to form embryogenic aggregates was lost. Thus, the non-embryogenic cells present within a mixed culture system were essential to the formation of embryogenic aggregates. When embryogenic tissues were isolated and cultured independently on a high glutamine-containing (2400 mg l⁻¹) medium, dry weights and endogenous levels of glutamine increased, and the tissue could generate a large number of embryogenic aggregates. Amino acid analysis of embryogenic and non-embryogenic cells from the maintenance culture indicated a higher level of glutamine was present in the latter. The high endogenous level of glutamine in the non-embryogenic portion of mixed cell masses may be the supplier of glutamine for maintaining the embryogenic property of the tissues.     

Specificity of action of piperidylcholine derivatives as substrates of cholinesterases of various origin

The review deals with study of enzymologic properties of a novel highly specific acetylcholinesterase substrate, N-(β-acetoxyethyl) piperidinium iodomethylate (“piperidylcholine”), and its 30 derivatives that were tested as effectors of cholinesterases of mammals and various species of Pacific squids. It was proven for the first time that responsible for specificity of action was structure of cyclic ammonium grouping of the alcohol part of molecule of the ester substrate. Analysis of specificity is performed based on enzymatic hydrolysis parameters—activity of catalytic center of cholinesterases and bimolecular constant of the reaction rate that are determined at optimal and low substrate concentrations. Among the specially synthesized group of thioester compounds there is revealed one more highly specific acetylcholinesterase substrate—N-(β-acetoxyethyl) piperidinium.     

Interconnection of parameters of regulation system of lipid peroxidation and of morphophysiological parameters of mouse liver

A complex analysis of seasonal fluctuations of the mean group parameters of the system of regulation of lipid peroxidation has been performed in liver of Balb/c mice. Association of lipid characteristics and morphophysiological parameters is studied in the Balb/c mouse liver. An inter-connection is revealed between the liver index and the amount of lysoforms of phospholipids, the scale and character of the interconnection differing essentially depending on proportion of phos-phatidylcholine in mouse liver phospholipids.
