BACKGROUND Resistin-like molecule alpha or found in inflammatory zone protein (Fizz1) is increased in pulmonary epithelial cells and also in limited amounts by other lung cells during various lung injuries and fibrosis. However, the direct role of Fizz1 produced in the pulmonary epithelium has not been determined. METHODS Fizz1 Transgenic mice (CCSP/Fizz1) were generated that overexpress Fizz...

We investigated in vivo and in vitro oscillatory mechanics in bleomycin-induced fibrotic lungs and correlated these with morphometric changes in the collagen-elastin matrix and contractile cells. Fischer rats received bleomycin sulfate (BLEO,1.5 U) or saline intratracheally. Four weeks later tracheal flow and tracheal and alveolar pressure (using alveolar capsules) were measured in open-chested...

Background: The purpose of this study was to compare the effects of saffron and methylprednisolone on bleomycin-induced pulmonary fibrosis in rats. Methods: This study was conducted in Bushehr, southern Iran in 2017.The animals were divided into four groups of five rats each. Three groups were injected with a single intratracheal dose of bleomycin (5 mg/kg). The fourth group was administered w...

BACKGROUND Though not in regular practice, intralesional (IL) bleomycin has been used for the treatment of warts since the 1970s and on the other hand, till now cryotherapy is quite regularly used to treat warts. AIM Our aim was to assess the evidence for the efficacy of IL bleomycin, in comparison with a control group of similar sample receiving cryotherapy, in the treatment of cutaneous war...

A comparison of the intracellular DNA strand scission activities of the antitumor drug bleomycin, three of its metal complexes, demethyl bleomycin A2, and iron-containing, redox-inactivated bleomycin in Ehrlich ascites tumor cells was performed by means of the alkaline elution technique. This comparison was aided by use of CoCl2 to eliminate or minimize post-cell lysis strand scission by bleomy...

Demethylation of Co-bleomycin A2 by heating yields three different complexes: form I and form II and "orange" Co-bleomycin-demethyl A2. These complexes can be separated by HPLC and show different 1H NMR spectra. Preparation of Co-bleomycin-demethyl A2 by chelation of bleomycin-demethyl A2 with cobalt yields a Co-bleomycin-demethyl A2, which is auto-oxidized into Co-bleomycin A1.

The effect of sequence and timing of hyperthermia (43 degrees) and bleomycin on Chinese hamster cells (V79) has been investigated. Hyperthermia preceding bleomycin treatment produced a greater cytotoxic effect than bleomycin treatment preceding hyperthermia. Furthermore, it appears that the combination of hyperthermia and bleomycin becomes less effective if the application of bleomycin is delay...

Combined therapy with clarithromycin (CLTR) and N–acetyl cysteine (NAC) may be useful in diseases with impaired oxidant-antioxidant balance, fibroblast proliferation, and collagen deposition such as pulmonary fibrosis. Activated inflammatory cells which accumulate in the lower airways may release increased amounts of reactive oxygen species (ROS) when accompanied with a deficiency in glut...

    Many studies have been performed for treatment or prevention of pulmonary fibrosis. However, no effective treatment has been found yet. The aim of this study was to investigate the effect of grape seed extract on bleomycin-induced lung fibrosis in rat. Hydroalcoholic extract of grape seed (Vitis vinifera) was prepared using maceration method. NMRI rats weighing 250-300 g were given...

Background and aim: Warts are the most common clinical presentation of human papilloma virus infection of human skin and mucosa. They are more common on hand, foot, face and genital area. They are benign skin colour lesions with different clinical forms. There is no specific treatment for them. In this trial the therapeutic effect of intralesional injection of bleomycin and cryotherapy on...
