Objective In previous studies, the relaxant, anticholinergic (functional antagonism), antihistaminic and its stimulatory effects on b-adrenoceptors of Nigella sativa have been demonstrated on guinea pig tracheal chains. In the present study, the relaxant effects of hydro-ethanolic, macerated aqueous (MA) and lipid-free macerated aqueous (LFMA) extract of Nigella sativa on tracheal chains of gu...

inhalational insulin was withdrawn from the market due to its potential to produce airway hyper-reactivity and bronchoconstriction. so the present study was designed to explore the acute effects of insulin on airway reactivity of guinea pigs and protective effects of salbutamol and ipratropium against insulin induced airway hyper-responsiveness on isolated tracheal smooth muscle of guinea pig. ...

Ammonia is an odorous substance, and it also forms secondary particle matter by causing chemical reactions with sulfur oxides nitrogen in the atmosphere. In this study, to evaluate ammonia emission from weaned pigs, concentration ventilation rate were measured mechanicaly-ventilated pig house. The measurement was conducted for about 45 days using INNOVA, a real-time measuring device based on ph...

Split-thickness pig skin was transplanted on severe combined immunodeficient mice so that pig dermal microvessels spontaneously inosculated with mouse microvessels and functioned to perfuse the grafts. Pig endothelial cells in the healed grafts constitutively expressed class I and class II major histocompatibility complex molecules. Major histocompatibility complex molecule expression could be ...

Attempts to obtain experimental values for the kinetic parameters of phenanthridine oxidation by guinea pig or rabbit liver aldehyde oxidase using common spectrophotometric methods have not been successful due to a lower limit of detection. In the present study, a new spectrofluorimetric assay in combination with a multivariate calibration method for enzymatic kinetic study of aldehyde oxidase ...

The microbiological quality of coastal or river water can be affected by fecal contamination from human or animal sources. To discriminate pig fecal pollution from other pollution, a library-independent microbial source tracking method targeting Bacteroidales host-specific 16S rRNA gene markers by real-time PCR was designed. Two pig-specific Bacteroidales markers (Pig-1-Bac and Pig-2-Bac) were ...

We previously found that the protein subunits of GPI-transamidase complex (e.g. PIG-U, PIG-T and GPAA1) play critical roles of oncogenes in human bladder and breast cancers manifesting their activities through signaling mechanisms that involve urokinase receptor/Stat3 and paxillin pathways. We report here that cigarette smoke extract (CSE) enhanced colony formation and invasiveness of certain h...

To understand molecular genetic characteristics of Korean pigs, the genetic relationships of nine pig breeds including two Korean pigs (Korean native pig and Korean wild pig), three Chinese pigs (Min pig, Xiang pig, and Wuzhishan pig), and four European breeds (Berkshire, Duroc, Landrace, and Yorkshire) were characterized from a 16-microsatellite loci analysis. The mean heterozygosity within br...

several therapeutic effects including hypnotic, antispasmodic, treatment of abdominal and chest pain and strengthening the heart have been described for the flowers of rosa damascena. north american indian tribes use a decoction of the roots obtained from the rosa damascena plant as a cough remedy and to treat eye problem. therefore, in the present study the antitussive effect of this plant in ...
