Background:
Herbal teas are rich in bioactive compounds with antioxidant, anti-inflammatory, and hepatobiliary supportive properties. Despite their long-standing use in Mongolian traditional medicine for liver and gallbladder health, comprehensive scientific data regarding the specific chemical composition and antioxidant activities of these polyherbal formulations remain limited.
Aim:
To evaluate the bioactive compound content and antioxidant activity of a polyherbal tea formulation for supporting liver and gallbladder function, with a focus on the influence of solvent concentration.
Materials and Methods:
The study utilized a polyherbal tea consisting of five plant species: Achillea asiatica Serg., Thalictrum foetidum L., Zygophyllum potaninii Maxim., Tanacetum vulgare L., and Rheum undulatum L. Samples were extracted using 30% and 70% ethanol. Preliminary phytochemical screening was performed using thin-layer chromatography (TLC). Total phenolic content (TPC) was determined using the Folin-Ciocalteu method, and total flavonoid content (TFC) was measured via the AlCl3 colorimetric assay. Antioxidant capacity was assessed through DPPH, ABTS+ and FRAP assays.
Results:
Phytochemical screening identified flavonoid derivatives, glycosides, and terpenoids in both extracts, while alkaloids were not detected. Quantitative analysis showed that the 70% ethanolic extract contained significantly higher levels of total phenolics (5.518±0.24%) and total flavonoids (1.513±0.023) compared to the 30% extract (p < 0.05). The 70% extract also demonstrated superior antioxidant potency, with lower (IC50) values for DPPH (55.37 µg/mL) and ABTS (86.08 µg/mL). Additionally, the FRAP assay confirmed the 70% extract had substantially higher reducing power (1440.84 µM Fe²⁺/L).
Conclusions
1. Phytochemical analysis confirmed that the polyherbal tea is primarily composed of flavonoid derivatives, glycosides, and terpenoids. The total phenolic and flavonoid contents in the 70% ethanolic extract were significantly higher (p < 0.05) than those in the 30% extract. 2. The free radical scavenging activity evaluated by DPPH (IC50) 55.37 µg/mL) and ABTS (IC50) 86.08 µg/mL) assays indicated that the 70% ethanolic extract possesses markedly stronger antioxidant activity compared to the 30% extract. 3. The iron ion reducing power (FRAP: 1440.84 µM/L) showed a concentration-dependent linear relationship. The positive correlation between polyphenol content and antioxidant activity confirms that this herbal formulation has a scientific basis for its traditional use in supporting liver and gallbladder function.

Background:
A rare angioproliferative condition of the larynx, Kaposhi sarcoma
typically affects the skin. Immunosuppressive treatment following organ
transplantation and human immunodeficiency virus infection are the causes.
Every type of Kaposi sarcoma has human herpesvirus-8. Laryngeal kaposi
sarcoma is uncommon in immunocompromised patients; since its initial identification
in 1965, 18 cases have been documented globally. A CO2 laser-assisted
laryngeal microsurgery is performed through the mouth cavity to remove
tumor when kaposi sarcoma of the larynx obstructs the airway. Case report: A
77-year-old woman complained of hoarseness, dry mouth, odynophagia, and
dysphagia three months prior when she arrived at the Mongolian-Japan Hospital.
Two years ago, she acquired hard, sensitive lumps that were palpable
on her right arm, left ankle, and right thigh. At that time, she was diagnosed
with Kaposiform hemangiodermatitis and treated at the National Center for
Dermatology. HIV test results were negative. Immunohistochemistry: CD31
+/-, CD34 /+/. Using flexible nasopharyngeal endoscopy to get the diagnosis:
There was a mass that was about 1.5–2–5 cm in diameter, bluish in color,
smooth and movable, and spongy and vascular on the larynx, on the nasopharynx,
behind the palatine tonsills, and supraglottic. Surgery: Through the
use of Kleinsasser laryngoscopy and a 0-degree endoscope, pathological tissues
were extracted under general anesthesia using a laryngeal microsurgical
instrument and a laparoscopic bipolar coagulator. The tissues were then sent
for histological evaluation, which revealed Kaposi sarcoma, sarcoma grade 1.
Results of treatment
Pain decreased and quality of life increased following
surgery. Upon nasopharyngeal endoscopy, the vocal cord mobility was normal
and the surgical incision was clean. Conclusion: Kaposi sarcoma is an
extremely uncommon illness. A lower quality of life and further issues can be
avoided with an early diagnosis and suitable therapy. It also needs to be continuously
monitored because it is a potentially repeatable disease.

Background:
The ichthyosis is a hereditary skin disease and inherited by autosomal dominant,
autosomal recessive and X recessive trait separately. The X-linked ichthyosis (XLI) is the most
frequent cutaneous disease and general incidence accounts for one in 2000-5000 male births.
Molecular pathogenesis of XLI is due to mutations, which are large deletion, missense, frame shift
and nonsense in STS gene. The vast majority of mutation frequency is a large deletion, which are
found in 85-90% of patients with XLI. An exon deletion of the STS can be detected by Polymerase
chain reaction with exon specific primers. An identification of STS gene mutation has various
importance such as 1) detection of mutation type; 2) for genetic counselling, 3) disease severity,
4) carrier detection.
Methods:
In the present study, pedigree analysis was used for type of inheritance, and Polymerase
chain reaction was used to detect a deletion in STS gene and normal control used. A deletion was
identified in case PCR bands were not visualized in agarose gels.
Results:
We included one patient, who had typical symptoms of XLI including dark, adherent
scales on skin. Mutation analysis of the STS gene showed that the patient had whole gene deletion
(del: Exon 1-10), which was demonstrated by the repeated amplification failure of exons. We used
a sample of healthy man as a wild type control, which showed normal amplification of STS gene’s
exons. Further, the current study will be focused on the screening of heterozygote large deletion
of Del: Exon1-10 of STS gene among patient’s female relatives.
Conclusion
An ichthyosis case enrolled in this study was inherited by X-recessive and we
identified whole exon deletion of STS gene in this patient.

The purpose of this study was to analyze the epidemiology of oral and maxillofacial surgery patients in Mongolia and advocate guidelines and programs to promote optimal oral health care. A fact-finding epidemiologic study on the patients who visited at Departments of Oral and Maxillofacial Surgery, at National Hospitals at Ulaanbaatar city and Province and other Central hospitals of Mongolian, from Jan to Dec, 2013.Total 12957 patients treated at inpatients care center at the above mentioned national hospitals. From Ulaanbaatar city were 4284 (36%) and from province were 7673 (64%). Patients from province were treated at FCH 69%, NTORC 6.4%, NCC 11.3%, NCMCH 27% and CMAFH 1.8%. Zero to 16 years, 17 to 36 years, 37 to 56 years and 57 or more years old patients were3072 (27.1%), 4224 (34.2%), 3218 (26.9%) and 1412 (11.8%), respectively. Males and females were 6841 (53%), 6090 (47%). Cases of the inpatients were as follows: infectious disease 5971 (49.88), benign tumor 1039 (8.01%), trauma & injury 1799 (15%), salivary gland disease 2.41%, TMJ disease 2.8%, neuralgia and muscle pain 0.8% and others. 5 provinces have no Oral and Maxillofacial Surgeon and patients were referred to other central hospitals or to the Ulaanbaatar city. This study gives a topic of conversation about undergraduate dental education, continuing education and enough specialists in the region.
