By using ultrafiltration membrane with a certain porosity, it is possible to achieve selective fractionation of dimeric and monomeric alkaloids at the molecular weight level. With porosity of the membrane 100-150A° and filtration of alcohol extracts of Vinca rosea L. obtained from the aerial part of the plant, selective fractionation was achieved within the molecular masses from M+ 168 to M+ 426. In the fraction of minor alkaloids, a norharman (M+ 168), dihydrositsirikin (M+ 356) and vindorosine (M+ 426) were identified by the method of LC-MS/MS and GC/MS. The fraction of the minor alkaloids showed strong cytotoxic activity against the DLD-1 and WS-1 cell lines (Resazurin test), and according to the Hoechst test, to the cells of all A-549, DLD-1 and WS-1 lines.
利用具有一定孔隙率的超滤膜,可以在分子量水平上实现二聚体和单体生物碱的选择性分离。利用100-150A°的膜孔隙率和从蔓越菊地上部提取的醇提取物进行过滤,在M+ 168 ~ M+ 426的分子质量范围内实现了选择性分离。用LC-MS/MS和GC/MS方法分别鉴定了微量生物碱的组分,分别为norharman (M+ 168)、dihydrositsirikin (M+ 356)和vindorosine (M+ 426)。经Resazurin试验,该次要生物碱组分对DLD-1和WS-1细胞株均有较强的细胞毒活性;经Hoechst试验,该次要生物碱组分对A-549、DLD-1和WS-1细胞株均有较强的细胞毒活性。

Our study aimed to assess the activity of the blood antioxidant system in the animal model of alloxan-induced diabetes in rats.Diabetes in rats was induced diabetes by a single intraperitoneally injection of freshly prepared 12% aqueous alloxan solution ( 200 mg/kg). The glucose level was measured after 1, 2, 3, 10, 15, and 30 days from alloxan administration. The study included only those rats with blood glucose levels above 250 mg/dl on the 2nd day after alloxan administration.We investigated the activity of antioxidant enzymes, superoxide dismutase (SOD) and catalase (Cat) in the blood serum.The results of the studies show that the activity of enzymatic antioxidant systems in rats' blood sharply increased during the first 3 days after injection of alloxan. That may be due to the compensatory reaction of the body in response to alloxan-induced oxidative stress. Afterwards, the activity of SOD and Cat decreased, which may be due to the utilization of antioxidant proteins in the detoxification process of ROSs, their glycation and decreased level of the protein synthesis in the body at the intensive hyperglycemia and oxidative stress conditions.
本研究旨在评估四氧嘧啶诱导的大鼠糖尿病动物模型中血液抗氧化系统的活性。采用新鲜配制的12%四氧嘧啶水溶液(200mg /kg)单次腹腔注射诱导大鼠糖尿病。四氧嘧啶给药1、2、3、10、15和30天后测量血糖水平。本研究仅包括四氧嘧啶给药后第2天血糖水平高于250 mg/dl的大鼠。测定血清中抗氧化酶、超氧化物歧化酶(SOD)和过氧化氢酶(Cat)的活性。研究结果表明,注射四氧嘧啶后的前3天,大鼠血液中酶促抗氧化系统的活性急剧增加。这可能是由于机体对四氧嘧啶诱导的氧化应激的代偿反应。随后,SOD和Cat活性下降,这可能与ROSs解毒过程中抗氧化蛋白的利用、糖基化以及机体在剧烈高血糖和氧化应激条件下蛋白质合成水平下降有关。

Snoring and OSA are different Manifestations of the same pathophysiological disorder. Snoring Per se is not dangerous to overall health, but can become a social problem for the snorer as well as for the sleeping partner. Since the first description of uvulopalatopharyngoplasty by Ikematsu in 1964 numerous variations of surgical procedures of the soft palate for the treatment of primary snoring and OSA have been published.

Hepatocellular carcinoma (HCC) is the most common primary liver malignancy and is a leading cause of cancer-related death worldwide. Despite advances in prevention techniques, screening, and new technologies in both diagnosis and treatment, incidence and mortality continue to rise. Cirrhosis remains the most important risk factor for the development of HCC regardless of etiology. Chronic medical conditions such as diabetes mellitus and obesity increase the risk of HCC. Diabetes mellitus directly affects the liver because of the essential role the liver plays in glucose metabolism. It can lead to chronic hepatitis, fatty liver, liver failure, and cirrhosis
肝细胞癌(HCC)是最常见的原发性肝脏恶性肿瘤,也是全球癌症相关死亡的主要原因。尽管预防技术、筛查以及诊断和治疗方面的新技术取得了进展,但发病率和死亡率继续上升。无论病因如何,肝硬化仍然是HCC发生的最重要的危险因素。慢性疾病如糖尿病和肥胖会增加患HCC的风险。由于肝脏在葡萄糖代谢中起着至关重要的作用,糖尿病直接影响肝脏。它会导致慢性肝炎、脂肪肝、肝功能衰竭和肝硬化

Dacryocystorhinostomy (DCR) is the standard procedure for the treatment of acquired nasolacrimal duct obstruction (NLDO), which can be performed with an external or endonasal approach. Numerous variations of endonasal DCR have been described in the literature that report varying rates of success. The aim of this study is to describe the approach and success rate of endonasal DCR, in which the nasal mucosa, bone and lacrimal mucosa are sequentially removed.

ASPECTS OF ORAL DISEASE PREVENTION DURING PREGNANCY 怀孕期间预防口腔疾病的几个方面
Pub Date : 2022-01-29 DOI: 10.52340/jecm.2022.715

Pregnancy is characterized by quantitative and structural changes in oral diseases, which, in turn, contribute to the general health of both the pregnant woman and the child, and mark the perfect formation of the skeletal system of the latter. It is important to note that there are still no specially developed programs for the prevention of oral diseases in Georgia. All this points to the need to develop effective programs for the prevention of major dental diseases based on the study of the causes of deterioration of the dental status of women during pregnancy. Thus, the expediency of planning and implementing preventive measures during pregnancy is not in doubt. An exogenous and endogenous dental disease prevention plan developed by us can be recommended during pregnancy, considering the general's and dental status of the woman, to improve both the dental health of the pregnant woman and the antenatal prevention of the unborn child.
怀孕的特点是口腔疾病的数量和结构变化,这反过来又有助于孕妇和儿童的总体健康,并标志着后者骨骼系统的完美形成。值得注意的是,格鲁吉亚仍然没有专门制定预防口腔疾病的方案。所有这些都表明,有必要在研究怀孕期间妇女牙齿状况恶化的原因的基础上,制定有效的预防主要牙齿疾病的方案。因此,在怀孕期间规划和执行预防措施的权宜之计是毫无疑问的。在怀孕期间,考虑到妇女的一般状况和牙齿状况,可以推荐我们制定的外源性和内源性牙病预防计划,以改善孕妇的牙齿健康和未出生婴儿的产前预防。

Leiomyoma is a benign tumor of unknown etiology of the uterus. Leiomyoma is stimulated by an excess of steroids, disruption of apoptotic mechanisms, and local growth factors.We conducted a retrospective analysis of the operative material with leiomyoma of the reproductive period of women with the uterine body. The study revealed: a sharp increase in the incidence of intramural leiomyoma; Histological structural features are characteristic of proliferative, recurrent, and latent leiomyomas; Active products of the extracellular matrix, which is important not only in terms of leiomyoma growth, but it is likely to be among the factors that limit the free uncontrolled spread of tumor proliferate in the uterine body muscle and inhibit the assimilation process; Retrospective analysis of the material provides a basis for the search for molecular mechanisms of leiomyoma development. The results obtained will be important for the selection of drug treatment (in terms of inhibition of myocyte proliferative processes, expression of growth factors and activation of apoptosis).
平滑肌瘤是一种病因不明的良性子宫肿瘤。平滑肌瘤是由过量的类固醇、凋亡机制的破坏和局部生长因子刺激的。我们回顾性分析了子宫体女性生殖期平滑肌瘤的手术材料。研究表明:子宫壁内平滑肌瘤的发病率急剧增加;组织学结构特征为增生性、复发性和潜伏性平滑肌瘤;细胞外基质的活性产物,它不仅在平滑肌瘤生长方面很重要,而且很可能是限制肿瘤在子宫肌体中增殖自由不受控制的扩散和抑制同化过程的因素之一;材料的回顾性分析为寻找平滑肌瘤发展的分子机制提供了基础。获得的结果将对药物治疗的选择(在抑制肌细胞增殖过程,生长因子的表达和细胞凋亡的激活方面)具有重要意义。

Oesophageal adenocarcinoma represents the 6th common cause of cancer related deaths. Frequently oesophageal adenocarcinomas are developed from Barret’s oesophagus, which represents the metaplastic lesion of the lower third of the oesophagus, when squamous epithelium is replaced by glandular epithelium. It has been shown, that Barret’s metaplasia bears the risk of progression into dysplasia and later into malignant disease. However, this risk is different in different patients. Nowadays, there are many ongoing studies investigating the molecular markers of the progression of Barret’s oesophagus, which on the other hand represents an important information for the proper clinical management of this lesion. We discuss the potential markers of Barret’s oesophagus progression and related problematic issues in presented critical review.
食管癌是癌症相关死亡的第六大常见原因。食管腺癌通常由巴雷特食管发展而来,当鳞状上皮被腺上皮取代时,它代表了食管下三分之一的化生病变。研究表明,巴雷特化生有发展为发育不良和恶性疾病的风险。然而,这种风险在不同的患者中是不同的。目前,有许多正在进行的研究对巴雷特食管进展的分子标记物进行了研究,另一方面,这为正确的临床治疗该病变提供了重要的信息。我们讨论了巴雷特食管进展的潜在标志物和相关问题。

According to Georgian legislation, only doctors’ activities are regulated from healthcare professions. Although the Law of Georgia on Health Care includes the definition of ‘independent nursing practice’, its content (as well as the relevant professional responsibility) is not defined in the law or by-laws. Act of Georgian Law on Health Care establishes the obligation of the ministry to approve the list of nursing specialties and adjacent nursing specialties, which approved by the Order of the Minister of Labor, Health and Social Affairs of Georgia on April 15, 2004 №80/N, however, the act has not been used. Bachelor nursing programs have been established in Georgia since 2011 and significant reforms have been carried out in vocational nursing education, but principles for regulating nursing activities have not been developed yet. The majority (97%) of the countries in the world have legislation for regulating / governing nursing activities with a relevant regulatory body. The most common function of the regulatory bodies is authorization of nursing activities / practices. Georgia is among the 6 jurisdictions where nurses are not authorized (including Armenia, Argentina, Cape Verde, Mauritius and Togo). At the same point in 72% of countries participation in a continuing professional development system is a prerequisite for continuing nursing practice. Considering the info written above, significant systemic changes are important for development of nursing practice, including: Defining nursing as a regulated profession; Establishment of nursing regulatory body with appropriate mandate; Activation of Nurses Authorization Mechanism; Establishment of postgraduate education systems for nurses with continuing professional development and responsibility.
根据格鲁吉亚的立法,只有医生的活动不受保健专业的管制。虽然《格鲁吉亚保健法》包括了"独立护理实践"的定义,但其内容(以及相关的专业责任)没有在法律或附则中加以界定。《格鲁吉亚保健法》规定,该部有义务批准格鲁吉亚劳动、卫生和社会事务部长2004年4月15日第80/N号命令批准的护理专业和邻近护理专业清单,但该法案尚未实施。自2011年以来,格鲁吉亚已经建立了护理学士学位课程,职业护理教育也进行了重大改革,但规范护理活动的原则尚未制定。世界上大多数国家(97%)都有相关监管机构对护理活动进行监管的立法。监管机构最常见的职能是授权护理活动/实践。格鲁吉亚是6个未授权护士的司法管辖区之一(包括亚美尼亚、阿根廷、佛得角、毛里求斯和多哥)。与此同时,在72%的国家,参加持续专业发展系统是继续护理实践的先决条件。考虑到上面所写的信息,重大的系统变化对护理实践的发展是重要的,包括:将护理定义为一种受监管的职业;建立具有适当授权的护理监管机构;护士授权机制的激活建立具有持续专业发展和责任的护士研究生教育体系。
