The research presents data from a preclinical study on the anti-inflammatory effects of a sodium dichloroacetate and sodium valproate combination (DCA-VPA). The 2-week treatment with a DCA 100 mg/kg/day and VPA 150 mg/kg/day combination solution in drinking water's effects on the thymus weight, its cortex/medulla ratio, Hassall's corpuscles (HCs) number in the thymus medulla, and the expression of inflammatory and immune-response-related genes in thymocytes of male Balb/c mice were studied. Two groups of mice aged 6-7 weeks were investigated: a control ( = 12) and a DCA-VPA-treated group ( = 12).

Lung cancer is the most frequent cause of cancer death. Some human lung malignant tumors have a combined small-cell lung cancer (SCLC) and non-small-cell lung cancer (NSCLC) histology, with tumor cell phenotype changing during tumor progression. Valproic acid is used as an anti-seizure medication to treat migraine, and bipolar mood disorders.

Some studies state that laryngeal squamous cell carcinoma (LSCC) is associated with possible direct tumor cell seeding to percutaneous endoscopic gastrostomy (PEG) site. However, there is a lack of experimental proof that LSCC tumor tissue can adhere and grow in distant sites. Therefore, we aimed to investigate the growth pattern of LSCC implants on chicken embryo chorioallantoic membrane (CAM) and evaluate possible associations between clinical course of the disease and behavior of experimentally implanted LSCC tumors.

Objectives/hypothesis: To investigate the growth pattern of recurrent respiratory papilloma (RRP) implants on chicken embryo chorioallantoic membranes (CAMs) and to evaluate possible associations between the clinical course of the disease and the behavior of experimentally implanted RRP tumors.

Study Design: Experimental study.

Methods: Fresh 172 RRP tissue samples from 12 patients were implanted onto chick embryo CAMs.

Background/aim: To investigate tumor suppression as an indicator of malignization potential within endometrial polyps in asymptomatic postmenopausal women.

Materials And Methods: Immunohistochemical studies of the phosphatase and tensin homolog (PTEN) were performed. Cases included 52 benign postmenopausal polyps, 19 endometrioid carcinomas with coexisting benign polyps, and 12 polyps with foci of carcinoma.

Endometrial polyps in asymptomatic postmenopausal women are often incidentally found, yet only 1.51% of them are malignant. Their potential for malignant transformation has not been adequately addressed.

The study objective was to investigate a possible sodium dichloroacetate (DCA) pharmacological mechanism causing an increase in diuresis in rats. The aim was to define characteristics of 24-hour urinary Na, K, Cl, Ca, and Mg excretion in Wistar male rats and to evaluate effect of a single-dose DCA and repeated DCA dosage on diuresis. Six control and 6 DCA-treated male rats aged 5 to weeks after a single DCA dose and repeated dosage were tested.

We aimed to develop a chick embryo chorioallantoic membrane (CAM) model of recurrent respiratory papilloma (RPP) and to evaluate its morphological and morphometric characteristics, together with angiogenic features. Fresh RRP tissue samples obtained from 13 patients were implanted in 174 chick embryo CAMs. Morphological, morphometric, and angiogenic changes in the CAM and chorionic epithelium were evaluated up until 7 days after the implantation.

Background: The aim of this study was to develop chick embryo chorioallantoic membrane (CAM) model of laryngeal squamous cell carcinoma (LSCC) and to evaluate the morphological and morphometric characteristics and angiogenic features of it.

Methods: Fresh LSCC tissue samples obtained from 6 patients were implanted onto 15 chick embryo CAMs. Morphological, morphometric, and angiogenic changes in the CAM and chorionic epithelium were evaluated up to 4 days after the tumor implantation.

Objective: The aim of the study was to detect changes in left ventricular cardiomyocyte size and shape in response to chronic ischemia and loss of cardiac tissue (myocardial infarction) during the course of ischemic heart disease (IHD).

Material And Methods: Left ventricular cardiomyocyte dimensions (diameter and length) were estimated histomorphometrically, and their cross-sectional area and volume were assessed in 85 males who died suddenly out of hospital (within 6 hours of the onset of the terminal event) due to the acute first (preinfarction IHD group, n=53, aged 48.6+/-2.

Objective: The aim of the investigation was to determine morphological criteria of acute myocardial injures in sudden ischemic death.

Material And Methods: Morphological investigation of the whole myocardium and coronary arteries in 170 victims of sudden out-of-hospital death due to ischemic heart disease was performed in the framework of the international WHO program "Myocardial Infarction Register in Population" and joint (at that time) USSR-USA project on sudden death.

Results: It was established, that out-of-hospital sudden death due to ischemic heart disease in all cases is related to irreversible myocardial injury: 92.
