Background: Diabetes mellitus (DM) is a complex metabolic disorder involving many organs and can devastate the lives of affected individuals. It is characterized by chronic high blood glucose that could lead to morbidity and mortality. The number of people suffering from diabetes worldwide is increasing at an alarming rate. It is predicted that about 366 million people are likely to be diabetic by the year 2030. Since all of the previous studies have focused on the therapeutic role of (Allium polyrhizum Turcz. ex Regel) preparations in diabetes mellitus, we investigated the preventive effect of oral administration of (Allium polyrhizum Turcz. ex Regel) extract on the changes of biochemical factors and histopathology alterations in hepatic tissue caused by diabetes. Therefore, this study aimed to investigate the effect of water extract (Allium polyrhizum Turcz. ex Regel) on the metabolism of rats with diabetes induced by a high-fat diet and streptozotocin. Aim: To investigate the antidiabetic properties of aqueous extract of (Allium polyrhizum Turcz. ex Regel) and its beneficial effect on hematological parameters in streptozotocin-induced diabetic rats. Materials and Methods: Experimental was performed at the Institute of Mongolian Medicine and Chemistry, Inner Mongolia University. Male Wistar rats weighing (180 g) were obtained from The Animal Experimental Unit of Mongolia Medicine and Chemistry Research Center, Inner Mongolia University. The rats were housed in well-aerated individual cages in an animal room and maintained in a temperature-controlled room (24±25°C) with a 12 h light/12 h dark cycle, 50-60 % humidity. They were fed with normal commercial chow and water ad libitum. Throughout the experiments, animals were processed according to the suggested international ethical guidelines for the care of laboratory animals, and all experimental procedures were approved by the Animal Care and Use Committee of Inner Mongolia University. After 4 weeks, the rats were fasted for 8 h before blood sampling, water was not restricted. Blood samples were collected from the orbital venous plexus. Results: The blood glucose level was significantly increased in model group 24.14±2.28 mmol/L, to Control group 5.31±0.49 mmol/L. Oral administration of Allium polyrhizum Turcz.ex Regel treated group 10.5±4.05 mmol/L, Metformin treated group 9.05±2.71 mmol/L resulted in significantly decreased blood glucose levels less model group. Conclusion The results of this study indicate that Allium polyrhizum Turcz.ex Regel possesses hypoglycemic, hypolipidemic, and antioxidant effects in STZ-induced diabetic rats and therapy of diabetes and its complications especially when used for a longer period.

Background: Hepatocellular carcinoma (HCC) is a primary liver cancer originating from liver cells, classified as a chronic liver disease. This cancer ranks third in the world in terms of mortality rate. The MELD (Model for End-Stage Liver Disease) and Child-Pugh scoring systems are utilized to assess the prognosis of chronic liver diseases. Based on studies suggesting that certain blood test indicators, particularly red cell distribution width (RDW), could be used to predict the prognosis of liver cancer and other cancers, as well as serve as diagnostic markers, this topic was chosen to evaluate the clinical significance of RDW in hepatocellular carcinoma. Aim: The aim is to study some blood test indicators and compare them with the MELD score and Child-Pugh score systems in order to determine the prognosis of chronic liver diseases. Materials and Methods: A retrospective, single-center, cross-sectional study was conducted at Mongolia-Japan Hospital. Among 322 patients diagnosed with HCC, 24 patients were selected for the case group, and 37 patients with liver cirrhosis were included in the control group. Results: According to the research criteria, 61 patients were selected and divided into 3 groups, and statistical analysis was performed. In the detailed blood test, platelet count and WBC count showed statistically significant differences among the 3 groups (p< 0.024). In the biochemical tests, C-reactive protein (CRP) was p< 0.018, total bilirubin p< 0.001, and the mean albumin level p< 0.015, all showing statistically significant differences among the 3 groups. A statistically significant inverse correlation was observed between RDW-CV and the clinical MELD score (r=-0.356). Conclusion Platelet count, RDW, CRP, total bilirubin, and average albumin levels are significantly different across the studied groups. RDW-CV shows a moderate inverse correlation with MELD scores, suggesting its potential as a prognostic marker in chronic liver diseases. Further research with larger sample sizes is recommended to confirm these findings.

Background: Due to Mongolia’s harsh climate and seasonal limitations in fresh food supply, fruits, vegetables, and medicinal plants are often consumed in preserved forms. However, the preservation methods and storage conditions may significantly alter their antioxidant activity, which is crucial for mitigating oxidative stress and preventing chronic diseases. Objective: This study aimed to evaluate the antioxidant activity of 19 commonly consumed vegetables, berries, and dried medicinal plants under different storage conditions including fresh, cold storage (cellar), and frozen (-20°C). Methods: Samples were extracted in 80% methanol and tested using the DPPH radical scavenging assay. Absorbance was measured at 517 nm using a UV-Vis spectrophotometer. IC⁻⁻ values were calculated to compare antioxidant potency. Statistical differences were assessed using paired and unpaired t-tests with SPSS v27 (p<0.05) Results: Cold storage significantly reduced antioxidant activity in root vegetables, with IC⁻⁻ values increasing by 2.4 to 13.5 times (p<0.01), indicating diminished radical scavenging potencial. In contrast, frozen samples showed minimal change (p>0.05). Dried medicinal plants such as Rosa canina and Thymus serpyllum maintained strong activity, with IC⁻⁻<50 μg/mL. Conclusion Cellar storage leads to a notable decline in antioxidant capacity of common vegetables, while freezing is a more effective method for preservation. Dried medicinal herbs remain potent sources of antioxidants and may be recommended for year-round use in Mongolian diets.

Background: The synthesis of multifunctional nanoparticles by integrating the bioactive properties of the ethanol extract of Urtica dioica L. a medicinal plant widely distributed in Mongolia, with zinc oxide nanoparticles (ZnO-NP) serves as the foundation of the present study. The aim is to produce nanoparticles with synergistic antioxidant, anti-inflammatory, antibacterial, and anticancer activities. Objective: To synthesise dual-action nanoparticles (NPs) by integrating ZnO with the extract of Urtica dioica L. and to characterise their properties. Materials and Methods: The Control group, as ZnO-NPs, and the study group, as medicinal plant ethanol extraction loaded nanoparticles (UD-ZnO-NPs), were synthesised using green synthesis techniques. The morphology and particle size were characterised by Scanning Electron Microscopy (SEM), chemical bonding was analysed using Fourier Transform Infrared Spectroscopy (FTIR), and crystalline structure was examined by X-ray Diffraction (XRD). Hemolytic activity assays were conducted to assess cytotoxicity. Results: The Control and study group’s morphology and size distribution were uniform and spherical. The average particle size of the study group (UD-ZnO NPs) was 63 nm, while the control group (ZnO-NPs) was 77 nm. FTIR analysis showed that the basic chemical bonds in both types of nanoparticles were similar; however, additional peaks corresponding to the bioactive compounds from the Urtica dioica extract were detected in the UD ZnO-NPs. XRD analysis revealed that both types of ZnO-NPs investigated the same crystalline structure, consistent with the standard reference data (JCPDS No. 36 1451). Hemolysis assays showed that at concentrations ranging from 0.5 to 2.5 mg/ mL, the hemolytic activity was below 5%, indicating low cytotoxicity. Conclusion ZnO-NPs with and without Urtica dioica extract were successfully synthesized via a green method, yielding spherical, uniformly dispersed particles ranging from 63 to 77 nm in size. While the structural and crystalline characteristics of the NPs remained consistent, the presence of bioactive compounds was confirmed in the UD-ZnO-NPs. Hemolytic assays indicated dose-dependent cytotoxicity, highlighting the importance of concentration in biomedical applications.

Background: Identifying reliable biomarkers for early detection, risk stratification, and prognosis of CVD in the context of CKD is, therefore, of critical importance. Cystatin C has emerged as a potential biomarker capable of reflecting both cardiac injury and renal impairment, particularly in patients with arterial hypertension. This study aimed to evaluate the association between serum cystatin C levels, left ventricular hypertrophy, and chronic kidney disease in individuals with hypertension. Objective: To assess serum cystatin C concentrations in patients with left ventricular hypertrophy and chronic kidney disease secondary to arterial hypertension. Materials and Methods: A case-control analytical study was conducted, enrolling 44 patients aged 45 years or older with both left ventricular hypertrophy and chronic kidney disease due to arterial hypertension alongside a control group of apparently healthy individuals. Serum cystatin C levels were measured using immunoturbidimetric assay. Statistical analysis was performed using SPSS version 25.0. Group comparisons were made using independent-sample t-tests, while multivariate regression and receiver operating characteristic (ROC) analyses were employed to explore associations and the predictive value of cystatin C. Results: The mean serum cystatin C concentration in the case group was 1.6±0.1 mg/L, significantly higher than in the control group (0.88±0.03 mg/L, p<0.05). Similarly, the estimated glomerular filtration rate (eGFR) was markedly reduced in the case group (44.88±6.8 mL/min/1.73 m²) compared to the controls (92.88±3.4 mL/ min/1.73 m², p<0.05). In the case group, a statistically significant inverse correlation was observed between serum cystatin C levels and glomerular filtration rate (GFR), with a regression coefficient of β=−0.028 (p<0.006). Conclusion The elevated serum cystatin C levels (1.6±0.1 mg/L) and decreased eGFR (38.99±12.7 mL/min/1.73 m²) observed in the case group suggest that cystatin C may serve as a potential biomarker for the early diagnosis of left ventricular hypertrophy due to arterial hypertension and chronic kidney disease, as well as for predicting related complications.

Background: Discrepancies in the sensitivity to biological effects of the androgens, exerted through the binding of the hormone to the androgen receptor (AR), may also be involved in the inter-individual variation of T as well as in age related decline. The human androgen receptor (AR), located on chromosome Xq11-12, is a transcription factor regulating the development of male reproductive organs in the fetus and secondary sex characteristics at puberty in response to testosterone (T) and 5a-dihydrotestosterone (DHT). The AR contains two polymorphic regions, the (CAG)nCAA repeat encoding polyglutamine, and the (GGT)3GGG(GGT)2(GGC)n repeat encoding polyglycine, commonly referred to as the CAG and GGN repeats respectively. The aim of this study is to investigate the effect of the human androgen receptor genes CAG and GGN repeat polymorphisms in relation with androgen level.Materials and Methods: Sample collection: 180 male, the medical data of these volunteers were obtained and determined some androgen hormones at first phase of study in 2010-2011 (total testosterone (TT), free testosterone (FT) and bioavailable testosterone (BAT)). To determine CAG/GGN repeats length in exon of androgen receptor gene, using frozen serum as a source of deoxyribonucleic acid (DNA). DNA was extracted from blood samples (200 ml) using High PurePCR Template Preparation Kits.Results: The 180 men whose age is at least 40 were involved in our research and their average age was 55.1±10.3. The 46.7% (84) of the participants presents CAG gene, the 6.1% (11) of the participants presents GGN gene while the 25.5% (46) of the participants presents both CAG and GGN genes. However, the 21.7% of 39 men not presents CAG and GGN genes.Conclusion: The free testosterone level was significantly decreasing with aging. However, the appearance of CAG gene polymorphism was significantly higher in more aged people. Decline of free testosterone level in participants with CAG and [CAG+GGN] combined form was stronger than in people with GGN gene polymorphism and CAG, GGN both undetected people. But the level of bioavailable testosterone was decreasing with aging and the appearance of CAG gene polymorphism (r=-0.425, p=0.01) and [CAG+GGN] combined form (r=-0.491, p=0.028) was also increasing.
