Background: Meniere's disease is a condition caused by disturbances in the auditory and vestibular systems. It is characterized by symptoms such as dizziness, nausea, vomiting, and tinnitus. In the United States, the prevalence of Meniere's disease has been found to be 84 cases per 100,000 women and 56 cases per 100,000 men. Regionally, it is more common in less populated areas, and research has confirmed that the prevalence increases with higher household income. Aim: To evaluate the effectiveness of traditional medicine treatments and therapies for Meniere's disease. Results: The patient is a 43-year-old male, with symptoms of dizziness, vomiting, and tinnitus. Since 2023, he has sought care at the Central Hospital of Mongolian Medicine, where he received traditional medicine treatments including herbal therapy and other traditional therapies on three occasions. As a result, the frequency of dizziness has decreased and other clinical symptoms have improved. Conclusion Traditional medicine treatments have been shown to be effective in managing Meniere's disease by extending the interval between relapses, improving quality of life, and significantly reducing clinical symptoms.

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: Saliva as a non-invasive biological sample can be a game-changer in early disease detection and health risk assessment. Objective: To examine the association between participants' dietary patterns and the activity of salivary amylase, along with serum amylase levels in humans. Materials and methods: This study was conducted at the research laboratory of the Department of Biochemistry, School of Biomedicine, MNUMS. A total of 30 students aged 19–22 years participated in the study. Saliva samples were collected three times at one-week intervals, and one blood sample was collected from each participant, alongside a dietary questionnaire. The activity of the amylase enzyme in both saliva and serum samples was determined using the iodine-starch method. Results: When evaluating the amylase enzyme activity based on participants' carbohydrate intake, the result was p > 0.05, indicating no statistically significant difference. Similarly, statistical analysis of the use of mouthwash and vitamin supplements also showed p > 0.05, which means these variables had no statistically significant effect on amylase activity. The correlation between salivary and serum amylase activity was found to be r = 0.365, indicating a weak positive correlation, but the difference was not statistically significant. Conclusion The intake of carbohydrates, vitamins, and mouthwash does not significantly affect the activity level of the salivary amylase enzyme, according to research findings. However, external factors such as stress and air pollution have been shown to exert a measurable influence on its activity. A comparative analysis of enzyme levels in saliva and blood using amylase as a representative marker revealed similar activity levels in both fluids. This suggests that saliva may serve as a viable non invasive sample for detecting various biomarkers and diagnosing diseases. The results underscore the potential of salivary components, particularly amylase, as valuable indicators in diagnostic applications.

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.

Abstract Epilepsy, a neurological disorder characterized by recurrent seizures, affects millions of people worldwide. Significant advancements in both diagnostic and therapeutic approaches have greatly improved outcomes, particularly for individuals with drug-resistant epilepsy. Modern neurostimulation techniques such as Responsive Neurostimulation (RNS), Deep Brain Stimulation (DBS), and Vagus Nerve Stimulation (VNS) have demonstrated effectiveness in reducing seizure frequency in these patients. Additionally, emerging technologies like gene therapy and optogenetics are being explored to better understand the underlying mechanisms of epilepsy and hold promise as future treatment modalities.Traditional imaging techniques often fail to detect subtle epileptogenic zones. However, the introduction of ultra high-field 7T MRI scanners represents a major breakthrough. These advanced scanners use eight transmitters to generate higher-resolution images, reducing signal dropout and enabling the identification of previously undetected lesions. In one study involving 31 patients, 58% had their treatment plans modified based on 7T MRI findings, highlighting its potential to inform surgical decision-making. In terms of pharmacological treatment, newer medications such as sultiame, cannabidiol (CBD), and non-pharmacological approaches like the ketogenic diet have emerged as additional therapeutic options for drug-resistant epilepsy. These developments contribute to more effective, personalized management strategies for epilepsy. In summary, the landscape of epilepsy diagnosis and treatment is rapidly evolving. Innovations in imaging and therapeutic interventions are offering new hope for patients with drug-resistant epilepsy. Ongoing research and clinical trials remain essential to further refine these approaches and improve patient outcomes.

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.
