The state of the pituitary-thyroid system central and peripheral links (according to the levels of thyroid stimulating hormone (TSH) and thyroid hormones T4 and T3 in blood serum) were studied in 6- and 18-month-old rats under initiated circadian desynchronosis (CD) by the light regime inverting. The CD was simulated against the background of separate and combined eff ect of both the whole body cryostimulation (–120°C) (WBC) and injections of the nucleated cells (NCs) of human cord blood, applied preventively (for a day and week, respectively). In 6-month-old rats, the TSH level decreased under the CD and its initiation after separate NCs administration and combined with WBC (by 3.4, 3.9 and 6.3 times, respectively) and remained unchanged under CD against the WBC. In 18-month-old rats the TSH level was reduced only at CD by 1.8 times. The T4 level in rats of both age groups did not change under the CD as well as during its development against the background of a combined effect of WBC and NCs administration in 6-month-old animals and against the NCs injection in 18 months-old rats. The T4 level in rats of both age groups decreased at the background of separate effect of the WBC (by 1.6 and 1.4 times, respectively). In 18-month-old animals, the T4 increased under the CD development after a combined effect of WBC and NCs injection by 1.3 times. No changes in the T3 level were found.
采用光照逆转法研究了6月龄和18月龄大鼠在初始性昼夜节律不同步(CD)下垂体-甲状腺系统中枢和外周环节的状态(根据血清中促甲状腺激素(TSH)和甲状腺激素T4和T3的水平)。在全身冷冻刺激(-120°C)和预防性注射人脐带血有核细胞(NCs)单独和联合作用的背景下模拟CD(分别为1天和1周)。在6个月大的大鼠中,TSH水平在分别给予nc和WBC后分别降低了3.4倍、3.9倍和6.3倍,并在CD对抗WBC时保持不变。在18个月大的大鼠中,TSH水平仅在CD时降低了1.8倍。两个年龄组大鼠的T4水平在CD下以及在其发育过程中没有变化,背景是6月龄大鼠的WBC和NCs联合施用以及18月龄大鼠的NCs注射。在白细胞单独作用的背景下,两组大鼠的T4水平分别下降1.6倍和1.4倍。在18月龄的动物中,WBC和NCs联合作用后,T4在CD发育过程中增加了1.3倍。T3水平未见变化。

In this work, we experimentally substantiated the possibility of correcting the cytokine profile to reduce the inflammation in mice with adjuvant arthritis (AA) via combined use of lyophilized human cord blood leukoconcentrate (lHCBL) and cryopreserved human placental extract (cHPE). Adjuvant arthritis was modelled in CBA/H mice. To day 7 after pathology induction, the animals were injected with lHCBL and cHPE singly or in combination. To days 14 and 28 of observation, all the introduced products showed a therapeutic effect. To 28 day of observation, the efficiency of combined use of lHCBL and cHPE was 3.1 and 2.5 times higher vs. the monotherapy (respectively), likely resulting from their synergy in respect to a decrease in arthritis index, TNFα concentration, impact of lHCBL and cHPE on IFNγ and IL-6 levels, correspondingly.
在这项工作中,我们通过实验证实了通过联合使用冻干的人脐血白细胞浓缩物(lHCBL)和冷冻保存的人胎盘提取物(cHPE)来纠正细胞因子谱以减少佐剂性关节炎(AA)小鼠炎症的可能性。在CBA/H小鼠中建立佐剂性关节炎模型。至病理诱导后第7天,对动物单独或联合注射lHCBL和cHPE。到观察的第14天和第28天,所有引入的产品都显示出治疗效果。观察28天后,联合使用lHCBL和cHPE的效率分别是单一治疗的3.1倍和2.5倍,这可能是由于它们在关节炎指数、TNFα浓度、lHCBL与cHPE对IFNγ和IL-6水平的影响方面的协同作用。

In this research, we have studied the mitotic activity of bone marrow when applying medicinal leeches and short-term hypothermia. The bone marrow mitotic indices were compared within an immediate examination of the thigh removed from the body and during a short-term hypothermia. As a result, no statistical differences were found between the mitotic levels during immediate examination and a short-term hypothermia in the intact animals and those after medicinal leech application, that evidenced to a hypothermal fixation of initial level of this index, preservation of biomembrane physiological state prior to hypotonic stress and cell morphology. The used here short-term hypothermia on bone marrow cells may be included in the multi-profile algorithm of laboratory analysis when studying a mitotic index in actively proliferating cells.
在本研究中,我们研究了在应用药物水蛭和短期低温时骨髓的有丝分裂活性。在对从体内取出的大腿进行即时检查时和在短期低温下比较骨髓有丝分裂指数。因此,在立即检查和短期低温期间,完整动物的有丝分裂水平与用药水蛭后的有丝细胞分裂水平之间没有发现统计差异,这证明了该指数的初始水平的低温固定,在低张应激和细胞形态之前保存了生物膜生理状态。当研究活跃增殖细胞中的有丝分裂指数时,这里使用的对骨髓细胞的短期低温可以包括在实验室分析的多轮廓算法中。

Production of reactive oxygen species (ROS) and protein state of membrane-cytoskeleton complex (MCC) in the erythrocytes, subjected to freeze-thawing with polyethylene glycol (PEG) and subsequently transferred into physiological conditions in vitro after cryoprotective agent removal were examined. Results of SDS-PAGE with β-mercaptoethanol showed a decrease in spectrin content in the MCC profile of cryopreserved erythrocytes. The using of diamide revealed an increase in the accessibility of –SH groups of spectrin for the reagent and an enhanced level of high molecular weight polypeptide complexes relative to the control. A decrease in the content of protein band 8 (peroxiredoxin) in the MCC of cryopreserved erythrocytes revealed by SDS-PAGE with β-mercaptoethanol is apparently associated with a change in its localization caused by an increased ROS production at the previous stages of cryopreservation. At the same time, the absence of significant changes in the ROS production relative to the control upon the metabolism reactivation in erythrocytes indicated the ability of cryopreserved cells to control the oxidative processes during short-term incubation.
检测红细胞中活性氧(ROS)的产生和膜细胞骨架复合物(MCC)的蛋白质状态,用聚乙二醇(PEG)冷冻解冻,然后在去除冷冻保护剂后转移到体外生理条件下。β-巯基乙醇的SDS-PAGE结果显示,冷冻保存的红细胞MCC图谱中的spectrin含量降低。二酰胺的使用表明,相对于对照,spectrin的-SH基团对试剂的可及性增加,高分子量多肽复合物的水平提高。β-巯基乙醇的SDS-PAGE显示,冷冻保存的红细胞MCC中蛋白带8(过氧环氧乙烷)含量的降低显然与冷冻保存前阶段ROS产生增加引起的定位变化有关。同时,相对于红细胞中代谢再激活的控制,ROS产生没有显著变化,这表明冷冻保存的细胞在短期孵育期间控制氧化过程的能力。

Here we have studied the effect of low-temperature storage of the placenta at different temperatures on anti-inflammatory activity of its extracts in cell models of erythrocyte thermohemolysis and adenosine-5’-diphosphate-induced platelet aggregation. The wound-healing effect of cryopreserved placental extracts was also evaluated in rat thermal burn model. When preserving placenta for up to a month, the temperature of storage was shown to cause no significant impact on the percentage of inhibition of erythrocyte thermohemolysis and platelet aggregation by the extracts. Placental storage for three months at –20°C decreased anti-inflammatory activity of its extracts, and led to its complete loss during 6 months. Placental cryopreservation at –196°C enabled to preserve the anti-inflammatory and wound-healing activity. The cryopreserved placenta-derived extracts showed a pronounced positive effect on reparative process at third-degree (B) skin burn injury in rats.
在红细胞热溶血和腺苷5'-二磷酸诱导的血小板聚集的细胞模型中,我们研究了胎盘在不同温度下的低温储存对其提取物抗炎活性的影响。在大鼠热烧伤模型中也评估了冷冻保存的胎盘提取物的伤口愈合效果。当胎盘保存长达一个月时,储存温度对提取物抑制红细胞热溶血和血小板聚集的百分比没有显著影响。胎盘在–20°C下储存三个月会降低其提取物的抗炎活性,并导致其在6个月内完全丧失。-196°C的胎盘冷冻保存能够保持抗炎和伤口愈合活性。冷冻保存的胎盘提取物对大鼠三度(B)皮肤烧伤的修复过程具有显著的积极作用。

The effect of different storage modes for the seeds of winter rye breeidng sample (Secale cereale L. subsp. cereale var. vulgare Koern) on its longevity, germination and yield structure was studied. Seed samples with a moisture content of 5–7% were stored in an airtight container for up to 42 months at 4 and –20°C. Control of plant germination and assessment of yield-related traits were carried out for three years according to standard methods. The research findings demonstrated the variation of seed germination depending on the sample genotype. No differences were noted in the longevity of seeds after 30 and 42 months of storage under various temperature regimens. The results of the analysis of yield-related traits of plants for two or three consecutive years did not show any significant advantages when influenced by 4 or –20°C on the spike length, number of productive stems and the mass of grain derived from the spike. However, at the same time, differences were found for plant height and weight of 1,000 grains in some cases in the seeds stored at temperatures of 4 or −20°C.
研究了不同贮藏方式对冬黑麦育种样品种子的贮藏效果。研究了小麦品种(vulgare korn)的寿命、发芽和产量结构。水分含量为5-7%的种子样品在4°C和-20°C的密闭容器中保存长达42个月。按照标准方法进行了三年的植物发芽控制和产量相关性状评价。研究结果表明,种子萌发随样品基因型的不同而变化。在不同温度条件下,种子贮藏30个月和42个月的寿命无显著差异。连续2年或3年对植株产量相关性状的分析结果显示,在4°C或-20°C的影响下,在穗长、生产茎数和穗出粒质量上没有明显的优势。但与此同时,在4°C或- 20°C的温度下,有些种子的株高和1000粒重存在差异。

The study determines the peculiarities of the response of the central and peripheral links of to a cold stimulus in people with different levels of blood pressure (BP). The dynamics of blood pressure, heart rate, rheographic index and cardiorhythmography before and after the cold pressor test were evaluated. A significantly higher increase in systolic and diastolic BP in response to the cold pressor test was found in the persons with a normal high level of initial blood pressure (130/85–139/89 mm Hg) (p < 0.05). During the examination, a higher percentage of those with a hyperreactive blood pressure response was found (25%). In the experiment participants with initial blood pressure > 130/85 mm Hg a significant influence of the sympathetic nervous system on the cardiovascular system central and peripheral links in response to cold stress was observed. The individuals with normal (120/80– 129/84 mm Hg) and normal low (110/70-120/80 mm Hg) blood pressure showed a satisfactory response of the cardiovascular system to cold stress, so they should expect less health risks when working at low ambient temperatures.
这项研究确定了不同血压水平的人对冷刺激的中枢和外周环节反应的特点。对冷加压试验前后的血压、心率、流变学指标和心律学动态进行评价。在初始血压正常高(130/85–139/89 mm Hg)的人群中,冷加压试验后收缩压和舒张压的升高幅度明显更高(p<0.05)。在检查过程中,发现高反应性血压反应者的百分比更高(25%)。在初始血压>130/85毫米汞柱的实验参与者中,观察到交感神经系统对心血管系统中枢和外周环节的显著影响,以应对冷应激。血压正常(120/80–129/84 mm Hg)和正常低(110/70-120/80 mm Hg)的个体显示出心血管系统对冷应激的满意反应,因此他们在低环境温度下工作时应该预期健康风险较小。

The individuals with normal (120/80– 129/84 mm Hg) and normal low (110/70-120/80 mm Hg) blood pressure showed a satisfactory response of the cardiovascular system to cold stress, so they should expect less health risks when working at low ambient temperatures.","PeriodicalId":53457,"journal":{"name":"Problems of Cryobiology and Cryomedicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42950924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we have studied the osmotic parameters of erythrocytes frozen in the composition-modified media with glycerol and 1,2-propanediol. A decreased glycerol concentration in a cryopreservative and an increased content of impermeable protective component sorbitol were established to affect the erythrocyte characteristics at different stages of freezing and hypothermic storage. Reduction of 1,2-propanediol and NaCl concentrations when augmenting the sucrose content in cryopreservative agent enabled changing a two-stage mode of erythrocyte freeze-thawing to the single-stage one. The presented here modification of cryoprotective medium allowed to diminish the level of damage to erythrocytes during freeze-thawing-washing out, that might prevent the inflammation development in a body when transfusing these cells.
在这里,我们研究了用甘油和1,2-丙二醇组成的改性介质冷冻红细胞的渗透参数。在冷冻和低温储存的不同阶段,冷冻保存剂中甘油浓度的降低和不可渗透保护成分山梨醇含量的增加影响了红细胞的特性。当增加冷冻保存剂中的蔗糖含量时,降低1,2-丙二醇和NaCl的浓度,使红细胞冻融的两阶段模式变为单阶段模式。本文提出的冷冻保护介质的修饰可以降低冻融冲洗过程中对红细胞的损伤水平,这可能会防止在输注这些细胞时体内炎症的发展。
