The pathogenesis of chronic obstructive pulmonary disease (COPD) encompasses a number of injurious processes, including an abnormal inflammatory response in the lungs to inhaled particles and gases. Other processes, such as failure to resolve inflammation, abnormal cell repair, apoptosis, abnormal cellular maintenance programs, extracellular matrix destruction (protease/antiprotease imbalance), and oxidative stress (oxidant/antioxidant imbalance) also have a role. The inflammatory responses to the inhalation of active and passive tobacco smoke and urban and rural air pollution are modified by genetic and epigenetic factors. The subsequent chronic inflammatory responses lead to mucus hypersecretion, airway remodeling, and alveolar destruction. This article provides an update on the cellular and molecular mechanisms of these processes in the pathogenesis of COPD. During the past decade a plethora of studies have unravelled the multiple roles of nitric oxide (NO) in airway physiology and pathophysiology. In the respiratory tract, NO is produced by a wide variety of cell types and is generated via oxidation ofL-arginine that is catalyzed by the enzyme NO synthase (NOS). NOS exist in three distinct are forms: neuronal NOS (nNOS), inducible NOS (iNOS), and endothelial NOS (eNOS). NO derived from the constitutive are forms of NOS (nNOS and eNOS) and other NO-adduct molecules (nitrosothiols) have been shown to be modulators of bronchomotor tone. On the other hand, NO derived from iNOS seems to be a proinflammatory mediator with immunomodulatory effects. Finally, the production of NO under oxidative stress conditions secondarily generates strong oxidizing agents (reactive nitrogen species) that may modulate the development of chronic inflammatory airway diseases and/or amplify the inflammatory response.

Grass pollens are one of the most important airborne allergen sources worldwide. The Poaceaefamily comprises about 9000 species, 20 species from five subfamilies are considered to be the mostfrequent causes of grass pollen allergy, and the allergenic relationships among them closely follow theirphylogenetic relationships. The allergic immune response to pollen of several grass species has beenstudied extensively over more than three decades. Eleven groups of allergens have been identified anddescribed, in most cases from more than one species. The most complete set of allergens has so farbeen isolated and cloned from Phleum pratense (timothy grass) pollen. Based on the prevalence of IgEantibody recognition among grass pollen-sensitized individuals, several allergens qualify as major, butmembers of two groups, groups 1 and 5, have been shown to dominate the immune response to grasspollen extract. Isoform variation has been detected in members of several of the allergen groups, whichin some cases can be linked to observed genetic differences. N-linked glycosylation occurs in membersof at least three groups. Carbohydrate- reactive IgE antibodies have been attributed to grass pollensensitization and found to cross-react with glycan structures from other allergen sources, particularlyvegetable foods. Another cause of extensive cross-reactivity are the group 12 allergens (profilins), whichbelong to a family of proteins highly conserved throughout the plant kingdom and present in all tissues.Members of eight allergen groups have been cloned and expressed as recombinant proteins capableof specific IgE binding. This development now allows diagnostic dissection of the immune response tograss pollen with potential benefits for specific immunotherapy.

Rotenone is a specific inhibitor of the NADH dehydrogenase complex. In mitochondria, rotenone inhibitsthe oxidation of NADH to NAD, thereby blocking the oxidation of NAD and the substrates such asglutamate, alpha-ketoglutarate, and pyruvate. Rotenone also inhibits the mitochondrial respiratory chainbetween diphosphopyridine nucleotide and flavine.2, 4-Dinitrophenol – (DNP) is lipophilic weak acids that pick up a proton, transport across the mitochondrialinner membrane into the matrix, deprotonate, then exit as anions before repeating the catalytic cycle,and dissipating the proton gradient. In this situation, electrons continue to pass through the electrontransport system, reduce oxygen to water and metabolic rate, heat are increased, but ATP is lesssynthesized in this process.The macrolide antibiotic - oligomycin binds to the surface of the c8-10 ring of the Fo domain of ATPsynthase, making contact with two neighboring molecules and blocking proton flow, which explains theinhibitory effect on ATP synthesis. Intraperitoneal injection of oligomycin into the rat (0.5 mg per kg)reduces the oxygen consumption by about 50%; decreases ATP production by the aerobic pathway andincreases formation of lactate in blood serum. These changes may cause a decelerated metabolism andan increased formation of free radicals or ROS in membranes.

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.
