Abstract
AIM To explore the effect of montelukast on bradykinin-induced tracheal smooth muscle contraction of isolated guinea pig trachea. STUDY DESIGN To study the effect of bradykinin in the absence and in the presence of montelukast on the isolated tracheal smooth muscle of a guinea pig pretreated with indomethacin (10(-6)M), phentolamine (10(-5)M), and propranalol (10(-6)M), to eliminate the effect of endogenous prostaglandins and catecholamines. The trachealis smooth muscle activity was recorded through the Isometric Force Displacement Transducer on a Four Channel Oscillograph. A cumulative dose-response relationship was demonstrated by adding successive doses of bradykinin on the tracheal strips, starting with 11 μg to 77 μg of 10(-4) concentration. A similar procedure was repeated in the presence of montelukast 0.5 μg/ml, which, was equal to approximate C(max) achieved in vivo with a 10 mg oral dose of montelukast, and in the presence of 1 μg/ml of montelukast. STATISTICAL ANALYSIS Data was expressed as mean ± standard error (SEM), and was analyzed using the SPSS version 15. A P value of less than 0.05 was considered significant. RESULTS Bradykinin produced a dose-dependent, reversible contraction of isolated tracheal smooth muscle. Montelukast significantly reduced the bradykinin-induced tracheal smooth muscle reactivity and shifted the bradykinin curve to the right and downwards, in the presence of both concentrations of montelukast. The mean magnitude of response achieved with 77 μg of bradykinin in the absence of montelukast was 39 mm ± 6.26, in the presence of 0.5 μg/ml of montelukast it was 24.17 mm ± 4.11, and in the presence of 1 μg/ml of montelukast it was 13 mm ± 2.6. CONCLUSION It is concluded that montelukast significantly inhibits, in a dose-dependent manner, the bradykinin-induced contraction of the guinea pig tracheal smooth muscle, and alludes to an interaction between the bradykinin and leukotriene mediators.

Abstract
BACKGROUND Deep infiltrating endometriosis (DIE) is a specific type of endometriosis, which can be associated with more severe pelvic pain than other forms of endometriotic lesions. However, the mechanisms by which pain is generated are not well understood. METHODS DIE (n = 31) and peritoneal endometriotic (n = 40) lesions were sectioned and stained immunohistochemically with antibodies against protein gene product 9.5, neurofilament, nerve growth factor (NGF), NGF receptors tyrosine kinase receptor-A (Trk-A) and p75, substance P, calcitonin gene-related peptide, vesicular acetylcholine transporter, neuropeptide Y, vasoactive intestinal peptide and tyrosine hydroxylase to demonstrate myelinated, unmyelinated, sensory and autonomic nerve fibres. RESULTS There were significantly more nerve fibres in DIE (67.6 +/- 65.1/mm(2)) than in peritoneal endometriotic lesions (16.3 +/- 10.0/mm(2)) (P < 0.01). DIE was innervated abundantly by sensory Adelta, sensory C, cholinergic and adrenergic nerve fibres; NGF, Trk-A and p75 were strongly expressed in endometriotic glands and stroma of DIE. CONCLUSIONS The rich innervation of DIE may help to explain why patients with this type of lesion have severe pelvic pain.

Abstract
BACKGROUND AND PURPOSE The pharmacological properties of compounds NCX 1512 and NCX 1514, synthesized by linking the histamine H1-receptor antagonist cetirizine to NO-releasing spacer groups, are reported. The aim was to establish if the compounds retained the antihistamine action of the parent compound, to assess their efficacy as NO donors and to test if they had broader antiallergic activity than cetirizine in the lung. EXPERIMENTAL APPROACH Antihistamine activity of NCX 1512 and NCX 1514 was investigated in vitro in the guinea pig ileum, in tracheal rings (GPTR) and lung parenchymal strips (GPLP) of the guinea-pig. The NO-releasing capacity was investigated in vascular preparations; the isolated rabbit and guinea-pig aorta and guinea-pig pulmonary artery. Kinetics of NO release were assessed in a rat whole blood assay. KEY RESULTS Both NCX 1512 and NCX 1514 retained activity as H1-receptor antagonists in the guinea pig ileum and airway preparations. The NO-releasing NCX compounds relaxed the rabbit aorta, an action prevented by the guanylyl cyclase inhibitor ODQ (10 microM). NCX 1512 and NCX 1514 did not relax the antigen (ovalbumin) pre-contracted GPTR, whereas the NO donors NCX 2057 and DEA-NONOate relaxed guinea-pig pre-contracted vascular and tracheal preparations. Cetirizine (1-100 microM) and NCX 1512 (1-100 microM) reduced the cumulative (0.01-100 microg ml(-1)) ovalbumin-induced constriction in GPTR, but had no significant effect in GPLP. CONCLUSIONS AND IMPLICATIONS NCX 1512 and NCX 1514 act as antihistamines and NO donors. However, there was no improved effect compared to cetirizine on antigen-induced constriction of the central and peripheral lung.

Abstract
Human colonic circular muscle produces spontaneous phasic contractions that are reduced in ulcerative colitis. How the spontaneous phasic contractions develop and why they decrease in ulcerative colitis are not known. We found that spontaneous phasic contractions of normal sigmoid circular muscle strips were significantly reduced by 90-min incubation with tetrodotoxin (10(-5) M), which blocked neurokinin A release in basal conditions and in response to electrical stimulation. In addition, spontaneous contraction of human sigmoid colon was significantly decreased by the NK2 receptor antagonists MEN10376 (Asp-Tyr-D-Trp-Val-D-Trp-D-Trp-Lys-NH2) and NK2ra (Bz-Ala-Ala-D-Trp-Phe-D-pro-Pro-Nle-NH2) but not by atropine or by the NK1 antagonist FK888 (N2-[(4R)-4-hydroxyl-1-(1-methyl-1H-indol-3-yl)carbonyl-l-prolyl]-N-methyl-N-phenylmethyl-3-(2-naphthyl)-l-alaninamide), suggesting that NK2 receptors are involved in their development. The spontaneous phasic contractions were abolished by thapsigargin and cyclopiazonic acid and significantly decreased by the protein kinase C inhibitor chelerythrine and by the calmodulin inhibitor CGS9343B (1,3-dihydro-1-[1-[(4-methyl-4H,6H-pyrrolo[1,2-a]-[4,1]-benzoxazepin-4-yl)methyl]-4-piperidinyl]-2H-benzimidazol-2-one (1:1) maleate), suggesting that spontaneous phasic contractions may be mediated by Ca2+ release from intracellular stores and by a protein kinase C- and calmodulin-dependent pathway. In strips from patients with ulcerative colitis, spontaneous contractions were significantly reduced, and this reduction was partially restored by the hydrogen peroxide scavenger catalase. Neurokinin A release, however, was not affected. We conclude that spontaneous phasic contractions of human sigmoid circular smooth muscle may be mediated by activation of NK2 receptors, calcium release from intracellular stores, and activation of calmodulin and protein kinase C. In ulcerative colitis patients, spontaneous phasic contractions are decreased, and this decrease may be in part due to overproduction of hydrogen peroxide affecting sigmoid circular muscle.

Abstract
1. Scald injury in Sv129+C57BL/6 mice induced a temperature and time dependent oedema formation as calculated by the extravascular accumulation of [(125)I]-albumin. Oedema formation was suppressed in NK(1) knockout mice compared to wildtypes at 10 (P<0.01) and 30 min (P<0.001). However, at 60 min a similar degree of extravasation was observed in the two groups. 2. Kinin B(1) (des-Arg(10) Hoe 140; 1 micromol kg(-1)) and B(2) (Hoe 140; 100 nmol kg(-1)) antagonists caused an inhibition of oedema in wildtype mice at 10 and 30 min (P<0.001), but not at 60 min or at 30 min in NK(1) receptor knockout mice. 3. The inhibition of thermic oedema by des-Arg(10) Hoe 140 was reversed by des-Arg(9) bradykinin (0.1 micromol kg(-1); P<0.01) and also observed with a second B(1) receptor antagonist (des-Arg(9) Leu(8) bradykinin; 3 micromol kg(-1); P<0.01). Furthermore des-Arg(10) Hoe 140 had no effect on capsaicin (200 microg ear(-1)) ear oedema, but this was significantly reduced with Hoe 140 (P<0.05). 4. Scalding induced a large neutrophil accumulation at 4 h, as assessed by myeloperoxidase assay (P<0.001). This was not suppressed by NK(1) receptor deletion or kinin antagonists. 5. These results confirm an essential role for the NK(1) receptor in mediating the early, but not the delayed phase of oedema formation or neutrophil accumulation in response to scalding. The results also demonstrate a pivotal link between the kinins and sensory nerves in the microvascular response to burn injury, and for the first time show a rapid involvement of the B(1) receptor in murine skin.

Abstract
Tachykinins (TK) have been implicated in both bradykinin-(BK) and hyperpnea-induced broncho-constriction (HIB) in the guinea-pig. However, TKs appear to have an indirect effect in HIB by releasing leukotriene (LT)D(4). We postulated that BK may cause bronchoconstriction through a cascade involving TK and LTD(4). We examined the role of TK and LTD(4)in BK-induced bronchoconstriction in ventilated Hartley guinea-pigs. Respiratory resistance (R(rs)) was monitored for 2 h following insufflation of BK (150 nM). Animals were pretreated with propranolol, then with either neurokinin (NK)1 (CP-99,994)+NK2 (SR-48,968) receptor antagonists or pranlukast (90 microg or 900 microg), an LTD(4)antagonist. Control animals received no pretreatment. BK-induced bronchoconstriction was significantly lower in NK1/NK2 (128%+/-6% baseline R(rs)SEM) and pranlukast (90 microg; 205+/-22, 900 microg; 169+/-20) animals compared to controls (284+/-22), P<0.0001 ANOVA. Bile from control and saline challenged animals was analysed for LTD(4)by HPLC and radio-immunoassay. However, LTD(4)excretion rate showed no significant difference over a 2-h collection period following insufflation of either BK or saline, respectively; baseline =2.5 pmol/h+/-0.6 SEM vs. 2.3+/-0.2, 0-1 h=2.8+/-0.7 vs. 2.0+/-0.6, 1-2 h=2.3+/-0.6 vs. 1.7+/-0.7. We conclude that BK-induced bronchoconstriction is mediated in part through the release of both TK and LTD(4), but the latter is released in insufficient quantities to be detectable by biliary analysis.

Abstract
1. Bradykinin is suggested to play a role in the pathophysiology of several acute and chronic diseases, including allergic disorders such as asthma. In the present study, we have investigated the importance of bradykinin in mediating allergic inflammation in rats. 2. To this end we have tested the effects of the B2 receptor antagonists Hoe 140, FR173657 or FR172357 on the pleural inflammatory response triggered by intrapleural (i.pl.) injection of allergen (ovalbumin, 12 microg cavity(-1)) in 14 day-actively sensitized Wistar rats. Analysis of the pleural fluid effluent revealed a sequence of mast cell-dependent inflammatory events, including early protein exudation and neutrophilia and late pleural eosinophil influx. 3. Local treatment with Hoe 140 (0.1 and 1 microg cavity(-1)), FR173657 (1 and 10 microg cavity(-1)) or FR172357 (1 and 10 microg cavity(-1)) inhibited dose-dependently allergen-induced mast cell activation with impairment of pleural plasma leakage, neutrophil accumulation and late eosinophil influx. 4. Moreover, the B2 receptor antagonists also dose-dependently inhibited the allergic like inflammatory pleurisy triggered by bradykinin (50 microg cavity(-1)), which is characterized by acute mast cell degranulation, protein leakage and pleural eosinophil infiltration. 5. Taken together, our findings provide substantial evidence to suggest that bradykinin acting on its B2 receptors play a critical role in mediating allergic mast cell-dependent inflammation in rats, and suggest that B2 receptor antagonists may be useful therapeutically to control allergic dysfunction.

Abstract
A radioimmunoassay of the undecapeptide substance P (SP) and its application in rabbit lung superfusate has been developed. The assay was based on the use of a radioactive tracer, 125I-SP-Tyr8, which showed, with an excess of antibodies, a specific binding greater than 90% and a nonspecific binding lower than 2%. This tracer was stable for 4 weeks at -20 degrees C. Its specific radioactivity was 384 Ci/mmol. The assay's lower limit of detection was 10 pg/ml (0.7 fmol). The determination of SP in rabbit lung perfusate required extraction and concentration using octadecylsilane cartridges. Under these conditions, the recovery of SP from experiments on lung perfusates (n=4) was 75.0+/-4.5%, and the intraassay and interassay coefficients of variation were 7.3+/-1.9% and 10.7+/-1.3%, respectively. Amounts of SP released in rabbit lung perfusates were determined following stimulation of pulmonary C fibers with capsaicin (10(-4) M). During the stimulation period, the values of SP from lung perfusates (n=6) increased significantly when compared with baseline values.
