Abstract: The beneficial influence of many foodstuffs and beverages including fruits, vegetables, tea, red wine, coffee, and cacao on human health has been recently recognized to originate from the chain-breaking antioxidant activity of natural polyphenols, significant constituent of the above products. Therefore antioxidants have received increasing attention within biological, medical, nutritional, and agrochemical fields and resulted in the requirement of simple, convenient, and reliable antioxidant capacity determination methods. Many methods which differ from each other in terms of reaction mechanisms, oxidant and target/probe species, reaction conditions, and expression of results have been developed and tested in the literature. In this review, the methods most widely used for the determination of antioxidant capacity are evaluated, presenting the general principals, recent applications, and their strengths and limitations. Conclusion: In this review, numerous antioxidant capacity methods, which differ from each other in terms of reaction mechanisms, oxidant and target/probe species, reaction conditions, and expression of results. It is important that analysis conditions, substrate, and concentration of antioxidants should simulate real food or biological systems. The total antioxidant capacity value should include assays applicable to both lipophilic and hydrophilic antioxidants and regards the similarity and differences of both HAT and ET. The assays including various ROS/RNS such as superoxide anion, hydroxyl radical, hydrogen peroxide, singlet oxygen, peroxynitrite, nitric oxide, nitric dioxide have to be designed to comprehensively evaluate the antioxidant capacity of a sample.

IntroductionThe trace elements selenium is a constituent of the antioxidant enzyme glutathione peroxidase. Becauseit boosts the body’s antioxidant capacity, selenium is thought to have some ability to control cell damagethat may lead to cancer. Selenium low status has been linked to increased risk of various diseases, suchas cancer and heart disease.GoalInvestigate serum selenium level of adult mongolians and conduct age and gender coparartive analysisof the serum selenium content.Materials and MethodsCross sectional study was performed among the 2339 apparently healthy Mongolians of both gendersaged ≥18 years. In the study were used questionnaire and biochemical methods. Blood samples werecollected from all subjects and serum selenium concentration was measured by atomic absorptionspectrophotometry method using thermo fisher scientific analyzer.ResultsThe mean and confidence interval of serum selenium level in adult Mongolians was 0.78 μmol/l (95%CI0.77-0.79) and there was no significant difference between genders. Thus the mean was 0.77 μmol/l(95%CI 0.76-0.80) among women and in men it was 0.78 μmol/l (95%CI 0.76-0.80). Data analysisrevealed that older age group individuals were at risk of lowered serum selenium level. In particular,the oldest age group of over 60 years (females: 0.74 μmol/l, 95%CI 0.70-0.77; males: 0.68 μmol/l,95%CI 0.64-0.71). The difference in selenium status between age groups was statistically significant inboth sexes. The overall prevalence of serum selenium concentrations indicative risk of deficiency was59.7%, with no significant differences in the prevalence by genders. Survey findings revealed that riskof selenium deficiency had statistically significant difference between age groups among the surveyedmen.Conclusion: The mean value of serum selenium in adult Mongolians was 0.78 μmol/l and there was nosignificant difference between genders.

Background:
Lish-6 has been used for treatment pharyngitis, flu and throat disease. Lish-6 is composed from Eugenia
caryophylla. Thumb, Saussurea lappa C.B. Clark, Schizostachoum chinense. Rendle, Glycyrrhiza uralensis. Fisch, Gentiana algida Pall, Terminalia chebula. Retz. Anti-fever properties of these plants and their bio-active compounds have
extensively been studied.
Aim:
To determine the anti-fever effects of Lish-6.
Marerials and Methods:
Fever was induced by intravenous administration of lipopolysaccharide (LPS) at concentration
of 0.5 mg/kg. Lish-6 was given orally at concentration of 92 mg/kg, 1 and 6 hours after the LPS administration. Rectal
temperature wa measured 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 hours after the LPS administration. Paracetamoli was given orally
at concentration of 50 mg/kg. Blood levels of Prostaglandin E2
(PGE2) and interleukin-6 (IL-6) interleukin-1β (IL-1β)
were determined by enzyme linked immune sorbent assay using rat kits. Lung tissue was examined by histopathological
analysis.
Results:
The body temperature of rats in the normal group was 35.0±1.10С, while in the control group, periodic fever was
caused by the effect of lipopolysaccharide (p=0.001). But in the Lish-6 drug group, rectal temperature decreased steadily
(p=0.05). In addition, the IL-1β cytokine in the normal group was 3.24±0.31 ng/L and increased by 60.5% in the control,
indicating the development of the pathological model, while this parameter decreased by 31% in the Lish-6 drug group
(p=0.05). IL-6 cytokine in the normal animals was 21.1±0.2 pg/L and increased by 19.04% in the control, indicating the
development of the pathological model, while this parameter decreased by 8.3% in the Lish-6 drug group (p =0.05). PGE2
in the normal group was 43.2±0.3 ng/L, and it increased by 62.7% in the control group, indicating the development of a
pathological model, while this parameter decreased by 53.3% in the Lish-6 drug group (p=0.05).
Conclusion
Lish-6 traditional drug has the effect of reducing rectal temperature, IL-1β, PGE2 and IL-6 cytokines during
lipopolysaccharide-induced febrile pathology model.

Background:
Silybum marianum, as well as known milk thistle, has long been recognized for its hepatoprotective effects,
primarily attributed to its active flavonolignan complex, silymarin (an extract from water hyacinth fruit). While the
pharmacological effects of silymarin have been studied, research on bioactive peptides derived from Silybum marianum
remains limited.
Aim:
To evaluate the toxicity effects of silybum marianum peptides
Marerials and Method:
This study aimed to evaluate the potential toxicity of Silybum marianum peptide in mice through
a 14-day oral administration experiment. Twenty adult male C57BL/6 mice were divided into two groups: the experimental
group received 200 mg/kg of Silybum marianum peptide daily, while the control group received an equivalent volume
of saline solution. Physiological and biochemical parameters, including body weight, fasting blood glucose levels, liver
and spleen wet weights, as well as alanine aminotransferase (ALT) enzyme activity, were assessed to determine potential
toxic effects. This exploration aims to shed light on the toxicological effects of silybum marianum peptide in mice, providing
insights into its potential benefits and challenges.
Results:
Results indicated no significant differences between the experimental and control groups in terms of body
weight, blood glucose levels, or major organ wet weights. Additionally, ALT enzyme activity remained unaffected, suggesting
no detectable liver toxicity. Throughout the study, no abnormal behaviors, physical changes, or mortality were
observed in the test subjects. Mice in both the silybum marianum peptide and control groups exhibited shiny and soft
fur, normal activity, and regular food consumption. These findings indicate that Silybum marianum peptide exhibits good
safety and low biological toxicity under the tested conditions, supporting its potential use as a safe dietary supplement or
therapeutic agent.
Conclusion
At the designated dosage, silybum marianum peptide demonstrated good safety and low biological toxicity.

Background:
Lish-6 has been used for treatment pharyngitis, flu and throat disease. Lish-6 is composed from Eugenia
caryophylla Thumb, Saussurea lappa C.B.Clark, Schizostachoum chinense Rendle, Glycyrrhiza uralensis Fisch, Gentiana
algida Pall, Terminalia chebula Retz. Anti-fever properties of these plants and their bio-active compounds have
extensively been studied.
Aim:
To determine the pain relief and antibacterial effects of Lish-6.
Materials and Methods:
To conduct acute toxicity study using V.B. Prozorovsk method. Average lethal dose, lethal and
maximum nonlethal doses were determined. Acetic acid (1%-0.1 ml) was injected into the rat abdominal cavity to induce
pain. Wistar rat of either sex (n = 6) weighing 18–22g were used. All animals were withdrawn from food 2h before the start
of experiment and were divided in five groups. Group I was injected with normal saline (10ml/kg) as control, Diclodenk
was given orally at concentration of 25 mg/kg. Group II III, IV, V and VI were injected with Lish-6 was given orally at
concentrations of 9.2, 18, 36, 92, 184 mg/kg injection of acetic acid. The number of abdominal constrictions (writhes)
were counted of acetic acid injection for the period of 20 min. To determine the antibacterial effect by dilution method.
Results:
Average lethal dose of Lish-6 was found to be LD50=0.92 (0.6-1.04) g/kg suggesting that it is slightly toxic animals.
Control group animals abdominal constrictions 72.4±8.8. Lish-6 concentrations of 9.2, 18, 36, 92, 184 mg/kg group
animal reduced acitic acid induced pain by 41.9-78.7% suggesting that it is pain relief effect (p<0.001). 4 g of Lish-6
medicine is active against gram-positive bacteria (S.aureus, Streptococcus pneumonia). However, it is inactive against
gram-negative bacteria. In other words, Lish-6 medicine inhibits the growth of methicillin-resistant and non-resistant
S.aureus bacteria at a dose of 500 mg. It was also found to inhibit Streptococcus pneumonia at a dose of 250 mg.
Conclusion
Average lethal dose of Lish-6 was found to be LD50=0.92 (0.6-1.04) g/kg suggesting that it is slightly toxic
animal. Lish-6 reduced acitic acid induced pain by 41.9-78.7% suggesting that it is pain relief effect. Lish-6 traditional
drug has an antibacterial effect.
