Introduction. Cancer of unknown primary (CUP) is histologically defined as the presence of a metastasis of lymph node without detection of the primary tumor [1]. Approximately 3–15% of all cancers are designated as CUP [3. 4]. The diagnosis, treatment and monitoring of patients with laterocervical metastases of unknown primary involves a wide range of oncologic entities [5]. While we were studying patho-histological examination of cervical lymphadenopathy in Mongolian, werevealed unknown primary tumor. This is a goal of our study. Objectives of study are followings to differentiate whether primary lymphoma or metastatic cancer of cervical lymph node metastasis of unknown primary tumor and to reveal primitive origin of tumor using by basic and additional immunohistochemical markers.Goal.To determine the conclusive diagnosis in cervical lymph node metastasis of unknown primary origin by immunohistochemical techniqueMaterials and Methods. In this study, we examined immunohistochemically 30 cases of outpatient head and neck surgical unit of the National Cancer Center and dentistry and oral maxillofacial surgical unit of the State Central Hospital which were diagnosed as cervical lymphadenopathy. For immunohistochemical study, we applied an immunohistochemical panel in accordance with avidinbiotin- peroxidase complex method and used a basic and additional antibodies represented by CK(pancytokeratin), LCA, synaptophysin, chromogranin and HMB45. Result. In our study, there was 63.3% lymphoma, 36.7% metastatic cancer. Among them, there were 4 of digestive tract adenocarcinoma, 3 of squamous cell carcinoma /2-esophagus, 1-nasopharyngeal/, 2 of neuroendocrine tumor and 1 of melanoma.Distribution by age groups shows that 20-29 years were 4(13.3%), 30-39 years were 10 (33.3%), 40-49 years were 8 (26.7%), 50-59 years were 3 (10%), over60 years were 5 (16.7%). Gender distribution showed an increased incidence of males (56.7%, 17 cases) compared with females (43.3%, 13 cases).Conclusion: In our study, B cell lymphoma and digestive tract adenocarcinoma were the most common. In further, it is necessary to introduce an immunohistochemical method in patho-histological practice.

Abstract Mana-4, an herbal medicine, had been used to treat incomplete-mannered and infection-caused hot disease in Mongolian traditional medicine. It has already reported that Mana-4 acts as an anti-inflammation agent, an activator of T and B cells, an immune-modulator and an inducer of cellular proliferation. Moreover, it enhances the immune system and energy level of human body. It was confirmed that the main active compounds in Mana-4 are inulin and total flavonoids which are effective for many diseases. Drug formulation types are very important to delivery the drugs to the targeted tissues and organs without loss of active ingredients. Total flavonoids in the extract of Mana-4 and granulated Mana-4 was qualitatively evaluated by TLC and yellow-brown spots (Rf was 0.4) were found on TLC plates, indicating that the preparations contained flavonoids. Also, it confirmed that the appropriate extractor of total flavonoids from Mana-4 was 70% of ethanol. In conclusion, the tablet formulation from Mana-4 was successfully prepared and the quality requirements was allowable.

Background: Infections in respiratory systems have spread throughout the world without any restrictions including living places, public issues, and lifestyle. Three main causes of illnesses for the population of cities and rural areas were gastrointestinal diseases, respiratory diseases, and cardiovascular diseases. After investigated some medicinal herbs including Stelleria Chamaejasme L. and Oxytropis Pseudoglandulosa, it has been reported that they had antiinflammatory, analgesic, and wound healing effects. Lozenge formulation has some advantages for treatment application, such as easily absorbed, good bioavailability and ability of diminishing stomach irritation. In this study, we aimed to obtain a suitable extract from Stelleria Chamaejasme L. and Oxytropis Pseudoglandulosa for further lozenge formulation. Purpose: To obtain a suitable extract from Stelleria Chamaejasme L. and Oxytropis Pseudoglandulosa, and to conduct qualitative and quantitative studies for some biologically active substances Materials and methods: In this study, an aerial part of Stelleria Chamaejasme L. and Oxytropis Pseudoglandulosa were used, and the study was conducted in MUPS. For obtaining a suitable extract, the raw materials were extracted by remaceration, repercolation and circulation methods in 20% and 70% of ethanol and distilled water. The flavonoids and polyphenolic compounds in the extracts were determined by thin layer chromatography. Quantitative analysis for total flavonoids was performed by spectrophotometer. Results: According to the result, a yellow spot-on chromatogram was detected in extracted raw materials (Stelleria Chamaejasme L. and Oxytropis Pseudoglandulosa), indicating that flavonoid contained in the extracted solution.
The result was compared to standards of rutin (Rf=0.2) and quercetin (Rf= 0.94). Also, a black, blue spot-on chromatogram was detected in extracted raw materials (Stelleria Chamaejasme L. and Oxytropis Pseudoglandulosa), indicating that polyphenols contained in the extracted solution. The spots were compared to gallic acid as a standard substance. In the quantitative assay of total flavonoids in raw materials, black-green precipitation was revealed after procedure. From this result, remaceration and circulation techniques were suitable to extract the raw materials. Flavonoid content was 3.35±0.04% after using remaceration technique, which indicated that it was more suitable to extract the raw materials. Conclusions These results showed that the appropriate extracting solution for Stelleria Chamaejasme L. and Oxytropis Pseudoglandulosa was 70% of ethanol. In this case, 3.35±0.04% of flavonoid was extracted by remaceration technique.
