Osteoporosis and the fractures associated with it constitute a major public health concern. Osteoporosis is a systemic skeletal disease characterized by low bone density and microarchitectural deterioration of bone tissue with a consequent increase in bone fragility. A WHO Scientific Group on April 2000 estimated osteoporosis is well-defined disease that affects more than 75 million people in Europe, Japan and the USA, and causes more than 2.3 million fractures annually in Europe and the USA.In Europe, for example, the number of women over 50 years of age is projected to increase by 30%-40% between 1990 and 2025.Most studies suggest the required daily intake is between 1000 mg and 1500 mg in postmenopausal women not taking estrogen replacement therapy. This can be obtained from about three serves of dairy products per day. For example, one glass (250 mL) of milk, two slices (40 g) of Cheddar cheese, or one tub (200 g) of yoghurt each contains about 300 mg of calcium. In one French study involving vitamin D deficient institutionalized elderly patients, simple vitamin D3 (800 IU) and calcium (1200 mg/day) reduced hip fractures by 43%.The management of postmenopausal osteoporosis should be based on an individual risk/benefit analysis, time since menopause, presence or absence of estrogen with drawal symptoms, history of atraumatic fractures, and other medical conditions. Socioeconomic evaluation of osteoporosis can be undertaken to estimate the cost of disease, the effectiveness of treatments, and the effects of strategies to identify patients at high risk such as screening and case-finding, or to assess global strategies. Global strategies aimed at increasing the BMD of the general population have not been adequately tested, but general advice on lifestyle is an important component of patient care.

Cervical cancer is commonly caused by infection with human papilloma virus(HPV) and some risk factors are involved in the etiology of it.1 All over the world 437000 people are diagnosed with cervical disorders and half of them die due to cervical cancer.2 Annually 12000 new cases of cervical cancer are detected and 5000 women die because of it. In Spain about 2000 women are determined in the 3rd and 4th stage of the disease per year.3 Over the period 2000-2008 cervical cancer rate is 8 %among all cancers in Mongolia. Approximately 16 % of women’s cancer is cervical cancer. 4 In developing nations prevalence rate of cervical cancer is higher because of malnutrition, quality and framework for early detection are not satisfying and some reproductive risk factors also influence on it. 5 Worldwide diagnosing early and rapid management of precancerous condition and cervical abnormalities turn into main issue. Therefore based on these detection of premalignant lesion of cervix by colposcopy the main objective of the study. The overall goal of the study is to detect the premalignant lesion of cervix by colposcopy and determine of some risk factors and study the results.A total of 71 women, who are treated in Women’s inflammatory disease unit, Infertility and Women’s endocrine disorder unit are recruited for the cross sectional study. The women, who conducted the study were selected by accidently and colposcopy was done. They also have completed special questionnaires. The data were analyzed using the SPSS 19.0, Windows Office. The average age of the women was 38±9.4. Colposcopy was done 90.1% (n=64) of women, 9.9% (n=7) of women had not colposcopy. Among the women who had colposcopy, biopsies were taken 56.3% (n=36). During colposcopy we analyzed condition of cervix then we took biopsy from suspected areas and sent it histology laboratory. We compared predictive diagnosis, histology results after colposcopy and 33.3% (n=12) were identified as normal, CIN I was 52.7%, (n=19), CIN II was 5.5% (n=2), CINIII was 2.7% (n=1), cervical cancer is confirmed in 5.5% (n=2). We studied risk factors that can influence the cervical disorders among the women recruited in the study and age of first sexual intercourse (r=0.356, p=0.033), number of abortion (r=0.412, p=0.029) were statistically significant. However age of the women, parity, usage of contraceptive pills, smoking, number of sexual partners were statistically not significant.(p>0.05) When women’s age of first sexual intercourse is younger, cervical cancer disorder occurs30% greater comparing to women having first sexual intercourse later, (p<0.05, R=0.3), when number of abortion increases cervical cancer disorder increases 40%(p<0.05, R=0.41).

BACKGROUND
Bovine colostrums is the milk secreted by cows during the first few days after parturition. It
contains many essential nutrients and bioactive components, including growth factors,
immunoglobulins, lactoperoxidase, lactoferrin and cytokines ets. Lactoferrin has been reported
for its multifunctional properties such as antifungal, antibacterial, antiviral antioxidant and
anticancer activities. The aims of this study focused on the isolation and purification of lactoferrin
from Mongolian bovine colostrums. Lactoferrin purified using HiTrap DEAE an ion exchange
chromatography. Lactoferrin purification efficiency was about 60.5%. The single band of purified
lactoferrin has been observed in SDS-PAGE electrophoresis.
METHODS
Bovine colostrum was collected at a cow farm in the Darkhan province of Mongolia. At first
the cream was separated by centrifugation (10000 xg 20 min at 4oC). In order to separate the
whey, the samples were precipitated with 1mol/l to pH 4.6 and centrifuged at 10000 g 20 min
again. The samples of whey were stored at -18oC to the analysis. Lactoferrin was purified by
HiTrap DEAE an ion exchange chromatography using 0.005 M phosphate buffer (pH 7.7) and
linear gradient NaCl from 0.25M, 0.5M, 1M. During chromatography, protein in the eluents was
monitored by ultraviolet absorbation at 280 nm with the instrument. Purity test done by using
polyacrylamide gel electrophoresis under denaturated condition (SDS-PAGE) method by Laemmli
(1970). For HPLC determination of the lactoferrin by Shimadzu Nexera X2 HPLC system with UV/
VIS detector were used. Detection was carried out at the wavelength 280 nm. Separation was
performed on a chromatographic column Protein R C18 ,2.2 x 150 mm, 5 μm particle size. Linear
gradient and flow rate 0.2 ml/min were used. Mobile phase a consisted of water / acetonitrile/
trifluoroacetic acid ( 95:5:0.1). The column temperature was set at 40oC and injection volume
was 10 μl. Data were collected and evaluated by software Lab Solution. An external standard
method for quantification analytes was used.
RESULTS
Purified lactoferrin in the present study had a good concentration and purification efficiency
was about 60.5 %. Protein fraction from 1M NaCl gradient delivers sharp and clean peak to
HPLC chromatogram that fits intensity and retention time of standard bovine lactoferrin.
Ammount of lactoferrin in bovine colostrums was 0.6 mg/ml and it`s molecular weight 80 kDa as
a standard sample. The retention time of lactoferrin fraction which is purified by SDS-PAGE gel
electrophoresis. The peak of fraction same compared to the standard lactoferrin 5.8 minutes
by HPLC analysis.
CONCLUSION
Ion exchange chromatography shows reliable and easy isolation of lactoferrin from Mongol
bovine colostrum.

Background:
Cancer incidence and mortality are steadily increasing both
globally and in Mongolia. As these rates rise, traditional Mongolian medicine
has long utilized herbal formulas for the treatment of gastric and esophageal
cancers and precancerous conditions. One such formulation—Hot Natured
3 Herbs (HN3H)—comprises three species from the Ranunculaceae family:
Atragene sibirica L., Ranunculus repens L., and Pulsatilla bungeana L.. However,
scientific validation of its anti-tumor effects is essential. This study aimed
to investigate the effect of HN3H in a tumor-induced animal model.
Aim:
To identify the biologically active compounds of HN3H and evaluate their
effect in an experimentally induced tumor model in animals.
Materials and Methods:
The three herbs comprising HN3H—Atragene sibirica
L., Ranunculus repens L., and Pulsatilla bungeana L.—were collected
during their flowering stage (May–June) in Khishig-Undur, Bulgan province,
and dried according to official procedures. Extraction was carried out by maceration
in 96% ethanol at a 1:10 ratio. The concentrated extract was suspended
in water (1:1) and successively fractionated with dichloromethane, ethyl
acetate, butanol, chloroform, and n-hexane. The study was approved by the
Research Ethics Committee of the Mongolian National University of Medical
Sciences (Protocol №2020/03-04). A colorectal cancer model was established
by subcutaneous injection of MC-38 cells (Kerafast, USA) into C57BL/6 mice.
Immunohistochemistry was performed using CK20, CDX2, Ki67, and p53 antibodies
at 1:100 and 1:200 dilutions.
Results:
The ethanol extract of HN3H contained 2.98±0.04% total phenolics
and 2.16±0.05% total flavonoids. Body weight and tumor volume were
measured daily with three repetitions. All groups showed a time-dependent
increase in body weight. Mice in groups 1A and 1B received ethanol extract at
50 and 100 mg/kg doses; groups 2A and 2B received dichloromethane extract
at the same doses. The negative control group was administered 0.5 mg/kg
PBS orally, while the positive control group received intraperitoneal injections
of 5-fluorouracil (5FU) at 10 mg/kg twice a week. Tumor growth increased in a
time-dependent manner across groups. Compared to the negative control, tumor
volumes in four treatment groups showed statistically significant reduction
(p˂0.05), while no significant difference was observed when compared to the
positive control (p=0.08). Histological analysis revealed necrosis in all groups,
with variation in extent.
Conclusion
The ethanol extract of HN3H exhibited moderate levels of phenolic
compounds and a high concentration of flavonoids. HN3H extract inhibited
tumor progression and activated lymphocyte-predominant inflammation in
tumor tissues, indicating potential anti-tumor activity (p˂0.05).
