Background: Inflammatory bowel disease (IBD) is a chronic immune-related condition caused by interactions between genetics, immune dysfunction, gut microbiota changes, and environmental factors, often presenting as persistent or recurring diarrhea. Clinically, it commonly presents with chronic diarrhea and other gastrointestinal symptoms. The global prevalence of IBD is increasing, currently affecting approximately 0.5% of the population, with projections suggesting a rise to nearly 1% by 2030. Fecal calprotectin is a neutrophil-derived S100 calcium-binding protein that is elevated in intestinal mucosal inflammation and serves as a reliable noninvasive biomarker of inflammatory activity. Due to its high stability and close association with intestinal inflammatory activity, fecal calprotectin has been established as a dependable, non-invasive marker for identifying intestinal inflammation. In clinical practice, it is extensively used to distinguish IBD from functional gastrointestinal disorders, especially irritable bowel syndrome, among patients presenting with chronic diarrhea. However, its diagnostic utility in Mongolia remains underexplored, and this study aims to determine its sensitivity and specificity in inflammatory bowel disease and compare its diagnostic performance with other inflammatory markers. Aim: To determine the sensitivity and specificity of fecal calprotectin in inflammatory bowel disease and to compare it with other inflammatory markers. Materials and Methods: A total of 109 participants aged 18-87 years with chronic diarrhea, who attended the gastroenterology outpatient clinics of the Mongolia–Japan Hospital and Intermed Hospital between December 2024 and December 2025 and provided informed consent, were enrolled in this study. Data were collected using structured questionnaires, and laboratory investigations included complete blood count, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and measurement of fecal calprotectin levels from stool samples. Based on fecal calprotectin results, selected participants underwent colonoscopic examination as clinically indicated. Results: Among the 109 participants included in the study, 17.4% were diagnosed with inflammatory bowel disease (IBD), with a mean age of 47.41±15.52 years. Fecal calprotectin levels were significantly higher in the IBD group compared to the control group (p<0.001). Fecal calprotectin demonstrated a weak positive correlation with C-reactive protein (CRP) and leukocyte count (p=0.042, p=0.06), while no significant correlation was observed with erythrocyte sedimentation rate (ESR). At a cutoff value of 250 µg/g, fecal calprotectin showed a sensitivity of 94.4%, specificity of 69.2%, positive predictive value (PPV) of 37.8%, and negative predictive value (NPV) of 98.4%. Receiver operating characteristic (ROC) curve analysis identified an optimal cutoff value of approximately 400 µg/g (AUC=0.919, Youden index=0.724), at which the sensitivity remained 94.4% and specificity increased to 78.0%. In contrast, CRP and ESR demonstrated comparatively lower diagnostic performance, with AUC values of 0.640 and 0.644, respectively. Conclusion This study demonstrates that fecal calprotectin has superior diagnostic performance compared to conventional inflammatory markers in differentiating inflammatory bowel disease (IBD). An optimal cutoff value of approximately 400 µg/g yielded the highest sensitivity and specificity. Therefore, fecal calprotectin may serve as a valuable tool in clinical practice for both screening and diagnostic confirmation.

Background: Allergic and atrophic forms of chronic rhinitis are common among the population, characterized by a chronic progressive course with a tendency toward increasing prevalence. Worldwide, allergic rhinitis affects approximately 10–40% of adults and 2–25% of children. According to a study conducted in Mongolia, the prevalence of allergic rhinitis among adults in Ulaanbaatar was reported to be 23.6%, with an increasing trend anticipated in the future. In allergic and atrophic rhinitis, structural alterations occur in the nasal mucosa, including disruption of the normal architecture of the pseudostratified epithelium and ciliated cells, accompanied by changes in goblet cell number and dysfunction of their activity, resulting in a complex pathological process. In otorhinolaryngology practice in Mongolia, there is a relative lack of studies investigating the ultrastructural changes of the nasal mucosa in allergic and atrophic rhinitis. Aim: To compare ultrastructural and histological changes of the nasal mucosa in allergic and atrophic rhinitis. Materials and Methods: Ethical approval was obtained from the Research Ethics Review Committee of the Mongolian National University of Medical Sciences at the meeting held on April 24, 2020 (Protocol No. 2020/З-04). Appropriate ethical permission was also obtained from the EMJJ ENT Hospital. Nasal mucosal tissue samples were collected from surgically resected specimens of patients aged 20–45 years diagnosed with allergic and atrophic rhinitis. The mucosal specimens were processed at the Institute of Biomedical Sciences of the Mongolian National University of Medical Sciences. Samples were fixed and dehydrated according to the protocol, coated with 100 Å gold, and examined using a scanning electron microscope (FEI Quanta FEG 250, USA). In addition, paraffin blocks were prepared, sectioned at 4 μm thickness, stained with Hematoxylin and Eosin, and analyzed histologically. Results: In allergic rhinitis, the pseudostratified epithelium was relatively preserved; however, disorganization of ciliated cells, partial loss of cilia, and goblet cell hyperplasia were observed. In contrast, atrophic rhinitis showed epithelial thinning, near-complete loss of ciliated structures, glandular atrophy, and submucosal fibrosis. Conclusion Allergic rhinitis is associated with relatively mild and predominantly functional mucosal alterations, whereas atrophic rhinitis demonstrates severe structural damage with irreversible impairment of mucosal protective function.

Coating agents are used in medicine to protect tablets from air or moisture, to mask bitter tastes, or to provide special characteristics for drug release, such as enteric release. There are three main coatings: sugar coating , film coating, and enteric-coating. In this review, we discuss the status of the most commonly used pharmaceutical film coating materials and data were obtained from electronic databases such as PubMed, Google Scholar, and other scientific websites. There are various materials for creating a tablet coating, but the most commonly used material is a water soluble polymer which is used for making a water-soluble film coating.

Excipients are important in the composition of drugs and are the most important requirements for maintaining the stability of drug form, dosage, and physicochemical parameters. Excipients act as protective agents, bulking agents and can also be used to improve bioavailability of drugs in some instances Auxiliary substances included in the composition of medicines are classified as natural, animal, synthetic and semisynthetic. Excipients can become inactive due to chemical, microbiological and physiological effects. Commonly used pharmaceutical excipients are fillers, stabilizers, preservatives, flavor and aroma modifiers, binders, disintegrants, lubricants, lubricants, solvents, and coating agents. Excipients can be considered as indispensible component of medicinal products and in most of the formulations they are present in greater proportion with regards to active pharmaceutical ingredient, as it forms the bulk of the formulation it is always necessary to select an excipient which satisfies the ideal properties for a particular excipient. In this review, materials about coating agents widely used in pharmaceutical practice were compiled from electronic databases such as Pubmed, Google Scholar, and other scientific web pages, using keywords such as Drug excipient interaction, Stability in Oral Solid, and Excipient. .

The incorporation of botanical elements such as Inula helenium L., Astragalus mongolicus Bge., Iris tenuifolia Pall., Ribes diacanthum Pall., and Oxytropis pseudoglandulosa Grubov plays a pivotal role in the formulation of immune-enhancing and kidney-protective Mongolian traditional medicines. These herbal constituents bear rich historical significance in traditional remedies. Ensuring the purity of these herbs is a vital stride in the production of efficacious supplements and medications. Thus, meticulous decontamination of microorganisms assumes paramount importance. The selection of an appropriate sterilization method is important for manufacturers. Sterilization methods divide within three main categories: thermal, chemical, and radiation. This spectrum encompasses many techniques, ranging from moist heat and dry heat to gamma irradiation, ethylene oxide, ozone, and UV treatment. This comprehensive review discusses the efficacy of gamma irradiation, dry heat, moist heat, and chemical treatments, presenting a comparative analysis of their merits. Practically, heat sterilization emerges as a simple and cost-efficient choice. The utilization of an autoclave, subjecting powdered spice paprika to temperatures between 108-125°C for 120 seconds, yielded a substantial reduction in microbial load without compromising the integral bioactive compounds. Gamma irradiation, a common practice in the healthcare and pharmaceutical sectors, stands as another choice in the area of sterilization techniques. Beyond sterilization, upholding rigorous standards of sanitation and hygiene remains a key in the preparations of medicinal plants.
