Болезнь Альцгеймера все чаще становится причиной ранней инвалидизацией и смерти. Попытки создания фармакотерапевтического средства, дающего эффективный результат в лечении этой патологии, до сегодняшнего дня не увенчались успехом. В данной статье приведены результаты экспериментальных исследований, ставящие целью создание более эффективного средства лечения данного заболевания.\u0000Материалы и методы. Объектом исследования явились полипренолы, выделенные из пихты сибирской (Abiessibirica Ledeb.). Эксперименты выполнены на 108 аутбредных половозрелых мышах-самцах стока СDI массой тела 28 – 30г (в возрасте 5 недель). Эффект суммы полипренолов на обучаемость и память исследовался в интервале доз – 5, 20, 50, 100, 200 и 500 мг/кг массы тела мыши. В качестве препарата сравнения использовали глиатилин в дозе 90 мг/кг. Экспериментальная модель нарушения когнитивных функций создавалась хроническим (в течение 20 дней) внутрибрюшинным введением скополамина в дозе 2 мг/кг. Нарушение когнитивных функций оценивались по изменениям показателей выработки и воспроизведения условного рефлекса пассивного избегания (УРПИ).\u0000Результаты и их обсуждение. Результаты проведенных экспериментов показали, что хроническое введение скополамина вызвало выраженное снижение воспроизводимости УРПИ. Одновременно с этим изучаемая субстанция в дозах 20 и 50 мг/кг. Глиатилин оказывал близкое по характеру действие. Авторы полагают что в развитии антиамнестического эффекта участвуют холинергические рецепторы.\u0000Заключение. Приведенное доклиническое исследование показывает, что найдено новое средство с антиамнестическим действием на основе суммы полипренолов Пихты сибирской (Abies sibirica Ledeb.), семейство Сосновые (fam. Pinaceae). Данное средство может быть использовано для лечения заболеваний нейродегенеративных патологических процессов, в частности болезни Альцгеймера.","PeriodicalId":21030,"journal":{"name":"Research Results in Pharmacology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141927328","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}

In this regard, the search for promising ways to control the carcinogenic transformation of tumor cells and the progression of malignant tumors expressing EGFR seems to be one of the most promising and developing areas of modern molecular pathology and pharmacology.\u0000Material and Methods: An antitumor activity of a novel compound, a pyridine carboxylic acid derivative LHT-17-19, was studied. The molecule was developed and synthesized at the Department of Chemistry, Drug Design and Technology of All-Russian Research Center for Biological Active Compounds Safety (Russia). The study was carried out in cell cultures of stomach cancer (Hs746T, AGS and MKN1) and patient-derived organoid (PDO) model of breast cancer (BC) expressing wild-type EGFR.\u0000Results: It was shown that LHT-17-19 induced concentration-dependent cytotoxicity of EGFR-expressing gastric cancer cells of all the aforementioned cultures. Pathomorphological, immunohistochemical and molecular validation of BC organoids derived from ductal breast carcinoma cells of a 68-year-old patient was done. PDOs were established as ER-negative, PR-negative, Her2/neu-negative, EGFR-positive with 35% of the Ki-67 expression index. In addition, the tumor cells translocation was resulted in a loss of ER expression and PDOs molecular pattern conversion towards a more aggressive triple negative type. PDOs incubation with 0.5-60.0 µM LHT-17-19 was accompanied not only by inhibition of their growth and proliferation, but also by significant cytoreduction.\u0000Conclusion: Thus, in two-dimensional and three-dimensional tumor cell cultures, the possibility of controlling the oncogenic expression of EGFR with the acridone compound 9-ammonium-3,3-dimethyl-3,4-dihydroacridine-1(2H)-OH L-2-hydroxybutanedivacate (LHT-17-19) was shown.","PeriodicalId":21030,"journal":{"name":"Research Results in Pharmacology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141350110","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}

Acute toxic liver damage was simulated with a single intraperitoneal injection of hydrazine hydrochloride at a dose of 50 mg/kg.

Progress in the field of reproductive technologies has improved the situation, but the issue has not yet been completely resolved. Infertility is diagnosed in 8-12% of couples of reproductive age; in Russia this figure exceeds 15%, and, according to WHO, it is a critical level. It is known that immunological factors can disrupt the reproductive process at the stages of folliculogenesis, ovulation, and implantation. These include vascular endothelial growth factor (VEGF), tumor necrosis factor-alpha (TNF-α) and others. The aim of this study: to assess the levels of VEGF and TNF-α in women with different outcomes of hormonal stimulation of the ovaries during the treatment of infertility using ART methods.\u0000Materials and methods: Based on voluntary informed consent, a simple open comparative randomized study was conducted with the participation of 71 women in the Volgograd region undergoing infertility treatment using ART methods. Inclusion criteria were the age up to 42 years inclusive and the anti-Mullerian hormone level over 1.2 ng/mL. Before ovulation stimulation with gonadotropins, data on ovarian reserve parameters were collected. Based on the results of stimulation, women were divided into 3 groups: Group 1 – with high and normal ovarian response – 10 or more oocytes were obtained (control group); Group 2 – with suboptimal ovarian response – 5-9 oocytes received; Group 3 – with a poor response – 4 or less oocytes were received. After venipuncture, which was performed in preparation for standard anesthesia, VEGF and TNF-α were quantitatively determined in the blood plasma using an enzyme-linked immunosorbent assay.\u0000Results: The study results showed a statistically significant difference in VEGF levels in follicular fluid and serum between the groups of women with high/normal, suboptimal and poor ovarian response to gonadotropin stimulation. A higher level of this marker was observed in the serum of patients with high/normal and poor response – 48.15±4.23 and 41.29±8.26 pg/mL, respectively, while in women with a suboptimal response a lower VEGF level was determined –29.19±3.41 pg/mL. The levels of VEGF in the follicular fluid of women included in the high/normal, suboptimal and poor response groups were 35.95±3.20; 27.42±2.53 and 41.22±3.23 pg/mL, respectively (Table 1). As for TNF-α, its serum level in women with a high and normal response was lower than in the patients with a suboptimal response. In the follicular fluid of patients of group 3, there was a higher level of TNF-α, compared to groups 1 and 2, where the indicator was almost the same. However, the difference was not statistically significant.\u0000Conclusions: Thus, VEGF is directly involved in the mechanisms of regulation of oocyte maturation and can be not only a marker of poor ovarian response, but also a predictor of unsatisfactory results of ovarian stimulation in t","PeriodicalId":21030,"journal":{"name":"Research Results in Pharmacology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140689849","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}
