Chronic obstructive pulmonary disease (COPD) is characterized by chronic airway inflammation. The initial step in the inflammatory process is overexpression of adhesion molecules, which leads to excessive transmigration of neutrophils. One of these adhesion molecules is ICAM-1 which is elevated in COPD patients. In this study we evaluated the influence of(More)
Vasculogenesis and hematopoiesis are co-localized in the embryonic body, but precise phenotypes of the cells contributing to these processes are not defined. The aim of this study was to characterize phenotypic profiles and location of putative vasculogenic and hematopoietic cellular progenitors in the embryonic mouse heart. Confocal microscopy, as well as(More)
Investigations on immune suppression and reconstitution of immune functions dependent on the presence of physiological microflora allow us to conclude that symbiotic microorganisms such as Lactobacillus sp. are essential for adequate activity of the defense system in humans. In addition to their beneficial influence on the intestinal microbial balance,(More)
UNLABELLED Deterioration of the immune system due to antibiotic therapy can be restored by immunomodulator application. In this paper we estimate the effect of ampicillin, amikacin, doxycycline, rifampicin, rifamycine and immunomodulator Tołpa Peat Preparation (TPP) on neovascular reaction induced in murine skin by human mononuclear cells (MNC) injection.(More)
The immunomodulatory activity of acetylshikonin (ACS) and isobutyrylshikonin (IBS) was studied in female and male inbred Balb/c mice, and in F1 hybrids (Balb/c x C3H). ACS and IBS were isolated from Lithospermum canescens Lehm. (Boraginaceae) roots. Splenocytes from mice fed 40 microg of ACS had higher proliferative potential in cultures with PHA than(More)
BACKGROUND AND AIMS Neutrophil activation is implicated in the pathogenesis of inflammatory processes such as chronic obstructive pulmonary disease (COPD). We wished to evaluate both in vivo and in vitro whether N-acetylcysteine (NAC) has an effect on the response of activated neutrophils. METHODS Ten healthy volunteers took NAC (600 mg daily) for 14(More)
N-acetylcysteine (NAC), owing to its antioxidant, mucolytic and anti-inflammatory properties, is used in the treatment of various pulmonary disorders. However, the direct effects of NAC on bronchoalveolar lavage (BAL) cells from patients suffering from interstitial lung diseases have not yet been studied. Therefore, the aim of the present work was to(More)
Angiogenesis is important for normal functioning of organism and its disturbances are observed in many diseases, called angiogenesis-related states. Reactive oxygen species (ROSs) play an important role in physiology, but high level of cellular ROSs is cytotoxic and mutagenic for the cells, i.e. it can lead to oxidative stress. In this review we discuss(More)
Disturbances of angiogenesis and oxidative stress can lead to many serious diseases such as cancer, diabetes or ischemic heart disease. Substances neutralizing oxidative stress are known as antioxidants. They can affect angiogenesis process also, and thus, they modulate therapy results. Antioxidants become more and more frequently used in order to maintain(More)
UNLABELLED PADMA 28, a natural herbal multi-compound remedy originates from traditional Tibetan medicine and possesses a variety of beneficial effects on experimental and clinical models of inflammation and atherosclerosis, as well as angioprotecive, antioxidative and wound-healing properties. The aim of the present study was to evaluate the in vivo(More)
