Abstract
OBJECTIVE To determine the multiple dose pharmacokinetics of a new extended release (ER) capsule formulation of tolterodine, compared with the existing immediate release (IR) tablet, in healthy volunteers. DESIGN Nonblind, randomised, 2-way crossover trial. PARTICIPANTS 19 healthy volunteers (7 females, 12 males), mean age 33 years (range 18 to 55 years). Prior to the study, all volunteers were classified as either extensive or poor metabolisers by cytochrome P450 2D6 genotyping. METHODS Volunteers received tolterodine ER 4mg once daily or tolterodine IR 2mg twice daily for 6 days (all doses given as the L-tartrate salt). A washout period of 7 days separated the 2 treatments. Serum concentrations of tolterodine, its active 5-hydroxymethyl metabolite (5-HM) and the active moiety (extensive metabolisers: sum of unbound tolterodine + 5-HM; poor metabolisers: unbound tolterodine) were measured for up to 48 hours post-dose on day 6 (steady state). Tolerability was also determined. RESULTS 17 volunteers (13 extensive metabolisers, 4 poor metabolisers) completed the study and were evaluable for both treatment periods. The 90% confidence interval for the geometric mean ratio of area under the serum concentration-time curve to 24 hours (AUC24) of the active moiety, for all volunteers combined, indicated equivalence for the 2 formulations. Pooled analysis also demonstrated that the peak serum concentration (Cmax) of the active moiety following administration of tolterodine ER was around 75% of that observed for the IR tablet, whereas the trough concentration was around 1.5-fold higher. Overall, the pharmacokinetics of tolterodine (irrespective of genotype) and 5-HM (extensive metabolisers only) were consistent with sustained drug release over 24 hours. Tolterodine ER was well tolerated. CONCLUSIONS The new once daily ER formulation of tolterodine 4mg shows pharmacokinetic equivalence (AUC24) to the existing IR tablet given at a dose of 2mg twice daily. Findings of lower Cmax for tolterodine ER may explain the significantly lower rate of dry mouth subsequently observed in patients with overactive bladder.

Abstract
Acromegaly is associated with cardiovascular disease. We studied vascular function and mean arterial blood pressure in transgenic mice overexpressing bovine GH. Mean arterial blood pressure was measured in conscious, unrestrained male and female bovine GH and littermate control mice during normal as well as high salt intake using telemetric devices. Structure in artificially perfused maximally dilated hindquarter vascular beds and vascular reactivity and endothelial function in small mesenteric vessels were studied in female bovine GH and control mice. Mean arterial blood pressure was increased in female bovine GH transgenic (126 +/- 3 mm Hg) and male bovine GH transgenic (129 +/- 4 mm Hg) compared with female (109 +/- 3 mm Hg, P < 0.05) and male (111 +/- 3 mm Hg, P < 0.05) controls respectively. Increased salt intake had no effect on mean arterial blood pressure. Perfusion studies showed a significant decrease in the average diameter of the female bovine GH transgenic hindquarter vascular bed (P < 0.05). The responses of isolated resistance arteries to nor-epinephrine, potassium-induced depolarization, acetylcholine, or sodium-nitroprusside did not significantly differ between bovine GH transgenic and control mice. We conclude that the phenotype of the bovine GH transgenic mice includes a salt-resistant form of hypertension. Furthermore, the increase in mean arterial blood pressure is accompanied by a significant structural narrowing of the resistance vasculature without changes in vascular reactivity or endothelial function. The results imply that hypertension in bovine GH transgenic mice is maintained mainly by a structurally based increase in peripheral vascular resistance.

Abstract
OBJECTIVE To investigate whether left atrial appendage outflow velocity alone or in relation to left atrial diameter is a superior predictor of sinus rhythm maintenance after cardioversion compared with traditional clinical or echocardiography parameters. DESIGN Sixty-two patients with their first episode of atrial fibrillation were examined using echocardiography before DC-cardioversion. At one month's follow-up, 42 patients had maintained sinus rhythm (group A), and 20 had relapsed into atrial fibrillation (group B). There were no differences in arrhythmia duration or antiarrhythmic therapy between the groups. RESULTS Left atrial diameter measured by echocardiography was smaller in group A (42 mm, 95% CI 40.9-44.1 mm) compared with group B (46 mm, 95% CI 43.4-48.2, p < 0.05). Patients in group A had a higher left atrial appendage outflow velocity at 0.44 m/s (95% CI 0.39-0.49) compared with 0.34 m/s (95% CI 0.30-0.37) in group B (p < 0.01). The ratio of left atrial appendage flow to left atrial diameter was 0.011 (95% CI 0.009-0.012) in group A compared with 0.008 (95% CI 0.007-0.009) in group B, and 63% (95% CI 33-78) of the patients in group A had velocity ratio >0.009 compared with 20% (95% CI 2-38) in group B, (p < 0.01). Stepwise multiple logistic regression analysis showed that a velocity ratio >0.009 was the only predictor for maintenance of sinus rhythm one month after cardioversion with an odds ratio of 6.4 (95% CI 1.9-23.8), (p = 0.004). CONCLUSION The ratio of left atrial appendage outflow velocity to left atrial diameter is superior to the traditionally used criteria for prediction of maintenance of sinus rhythm following DC-conversion of first-episode atrial fibrillation.

Abstract
The objective of this study was to investigate the influence of food on the pharmacokinetics of tolterodine, its active 5-hydroxymethyl metabolite (5-HM), and exposure to the active moiety (sum of unbound tolterodine + 5-HM) in healthy volunteers. Serum concentrations of tolterodine and 5-HM were measured for up to 12 hours after a single oral dose (2 mg) of tolterodine L-tartrate, administered either on an empty stomach or with a standardized medium-fat breakfast. All 23 subjects completing the study were classified as extensive metabolizers (phenotyped with debrisoquine). Pharmacokinetic data on tolterodine and the active moiety were evaluable for 22 subjects; all completing subjects were evaluable for 5-HM pharmacokinetics. Based on Cmax and AUC(infinity) ratios, relative bioavailability of tolterodine in the presence of food was 1.49 (90% confidence interval [CI], 1.35-1.71) and 1.53 (1.35-1.72), respectively. The pharmacokinetics of 5-HM and the active moiety were unaffected by food, as were the rates of drug absorption and terminal half-lives of tolterodine and 5-HM. Given that bioequivalence was observed for the active moiety underfed and fasting conditions, the authors concluded that coadministration of tolterodine with food is not expected to have any clinically relevant effects.

Abstract
We identified antibacterial components in human T and natural killer (NK) cells by using freshly isolated lymphocytes enriched for T and NK cells as starting material. After growing these lymphocytes for 5 days in the presence of interleukin (IL)-2, we isolated and characterized several antibacterial peptides/proteins from the supernatant-alpha-defensins (HNP 1-3), LL-37, lysozyme, and a fragment of histone H2B-although other active components were also present. We then used reverse transcriptase-polymerase chain reaction to search for expression of the gene coding for LL-37 in several B-cell lines, gammadelta T-cell lines, NK clones, and one monocytic cell line, with positive results, but found no expression in several alphabeta T-cell lines. The alpha-defensins (HNP 1-3) were also found to be expressed in several of these cell lines. To confirm the presence of these antibacterial peptides in lymphocytes, we localized them to NK, gammadelta T cells, B cells, and monocytes/macrophages by using double-staining immunohistochemical analysis of freshly isolated lymphocytes. We also found that primary cultures of lymphocytes transcribe and secrete LL-37 and that these processes are affected by IL-6 and interferon-gamma. In addition, we demonstrated that LL-37 has chemotactic activity for polymorphonuclear leukocytes and CD4 T lymphocytes, whereas others have shown chemotactic activity for human alpha-defensins (HNP 1-2). These findings suggest that microbicidal peptides are effector molecules of lymphocytes and that antibacterial activity previously shown to be derived from T and NK cells may be partly mediated by the antibacterial peptides LL-37 and HNP 1-3.

Abstract
Applied to environmental toxicology, proteome analysis may be used to isolate chemical-specific protein expression signatures (PES). In this project specific PES were isolated in mussels, Mytilus edulis, from the Baltic Sea subjected in the laboratory to treatment with copper (70 ppb), Aroclor 1248 (1 ppb), and to lowered salinity. Four mussels in each treatment group were acclimated in the laboratory for 24 h before beginning the 7-day exposure. Whole body tissue was homogenized and separated using two-dimensional gel electrophoresis. The protein gels were scanned to TIFF files and compared using MELANIE II 2D gel analysis software (BioRad). Protein expression signatures including proteins induced and repressed by exposure were isolated for each treatment group. The specificity of PES due to environmental changes shows promise in bioindication, toxicity testing and in helping identify possible toxicity mechanisms.

Abstract
AIMS Despite exclusion of left atrial thrombi by transoesophageal echocardiography, cardioversion-related thromboembolism has been reported in atrial fibrillation or flutter. To define a low-risk group for cardioversion without previous anticoagulation, patients were selected for immediate cardioversion if there were no thrombi, no echo spontaneous contrast and the outflow velocity of the left atrial appendage was greater than 0.25 m. s(-1)on transoesophageal echocardiography. METHODS AND RESULTS Two hundred and forty-two consecutive patients referred for cardioversion of atrial fibrillation or flutter with a duration of more than 2 days and no anticoagulation therapy were examined with transoesophageal echocardiography. After the transoesophageal echocardiography examination, patients who were eligible for immediate cardioversion were anticoagulated with low molecular weight heparin (dalteparin) subcutaneously, together with warfarin prior to cardioversion. Dalteparin treatment was continued until the patient had reached therapeutic prothrombin values. Based on the transoesophageal echocardiographic findings the patients were divided into two groups: immediate cardioversion, group A, with a mean age of 62+/-13 years (n=162); or conventional warfarin treatment before cardioversion, group B, with a mean age of 67+/-10 years (P<0.05) (n=80). In group A, lone atrial fibrillation or flutter was more common (53%; 95% CI: 45-61) compared to group B (34%; 95% CI: 23-44, P<0.05), while heart disease was more common in group B (45%; 95% CI: 34-56) compared to group A (31%; 95% CI: 24-39, P<0.05). Echocardiography revealed thrombi in 5% (95% CI: 2.6-8) of the patients, left atrial size was larger, fractional shortening lower, and a higher proportion had impaired left ventricular function in group B. No thromboembolic event occurred at or after cardioversion in any of the patients; however, before planned cardioversion one transitory ischaemic attack, one lethal stroke and one cardiac death occurred in three of the patients with thrombi despite warfarin therapy. One-month follow-up maintenance of sinus rhythm was 75% in group A compared to 45% in group B (P<0.01). CONCLUSION After using our transoesophageal echocardiographic exclusion criteria (no thrombi, no spontaneous echo contrast and left atrial appendage outflow velocity > or = 25 m. s(-1)) cardioversion can safely be performed in 2/3 of patients with atrial fibrillation or flutter without previous anticoagulation therapy. These patients maintained sinus rhythm significantly better after 1 month compared to patients with prolonged warfarin therapy before cardioversion.

Abstract
Growth hormone (GH) is important for skeletal growth as well as for a normal bone metabolism in adults. The skeletal growth and adult bone metabolism was studied in mice with an inactivated growth hormone receptor (GHR) gene. The lengths of femur, tibia, and crown-rump were, as expected, decreased in GHR-/- mice. Unexpectedly, GHR-/- mice displayed disproportional skeletal growth reflected by decreased femur/crown-rump and femur/tibia ratios. GHR-/- mice demonstrated decreased width of the growth plates in the long bones and disturbed ossification of the proximal tibial epiphysis. Furthermore, the area bone mineral density (BMD) as well as the bone mineral content (BMC)/body weight were markedly decreased in GHR-/- mice. The decrease in BMC in GHR-/- mice was not due to decreased trabecular volumetric BMD but to a decreased cross-sectional cortical bone area In conclusion, GHR-/- mice demonstrate disproportional skeletal growth and markedly decreased bone mineral content.

Abstract
Antibacterial peptides and proteins are an integral part of the epithelial defense barrier that provides immediate protection against bacterial invasion. In humans, alpha-defensins are mainly bactericidal effectors in circulating granulocytes, beta-defensin-1 is synthesized in epithelial cells, and LL-37 is produced in granulocytes but is also induced in skin epithelia during inflammation. To investigate the importance of these defense effectors in disease, we analyzed bronchoalveolar lavage fluid (BALF) for bactericidal activity. Antibacterial activity was found in BALF material from healthy individuals and sarcoidosis patients, with enhanced activity in BALF from the patients. The activity was present as several antibacterial components, of which we have so far characterized LL-37, lysozyme, alpha-defensins, and antileukoprotease. In addition, the antibacterial peptide LL-37 was located in alveolar macrophages, bronchial epithelial cells, and bronchial glands, suggesting that it has a defensive role in airway mucosa. In conclusion, the airway epithelium is protected by a complex antibacterial defense system. This is activated in sarcoidosis, and may explain why these patients seldom develop severe respiratory tract infections.

Abstract
Hypertrophy of the inferior turbinates is a common cause of nasal obstruction. Many cases respond to medical treatment with topical steroids or antihistamines. In some patients, however, this therapy is not sufficient and through the years many surgical procedures have been used to reduce the size of the inferior turbinates, but without any satisfactory long-term results. Furthermore, these procedures have often been painful to the patient and post-operative complications such as bleeding and crusting have not been uncommon. However, instead of conventional surgery of the turbinates, laser-surgery can be used to reduce their size. In order to investigate the long-term effect of such gross reduction of the turbinates we investigated the post-operative condition of 78 patients who had undergone CO2-laser-turbinectomy due to symptoms of nasal obstruction. Twenty-four to 36 months post-operatively three quarters of all the patients reported a marked decrease in nasal obstruction as well as a reduced frequency of nasal and sinus infections. No complications were reported and the procedure was without any discomfort to the patient. Thus, laser-turbinectomy seems to be an effective, simple and painless method for treatment of nasal obstruction due to hypertrophy of the inferior turbinates.

Abstract
In stroke patients several cardiac changes associated with embolism can be detected with transoesophageal echocardiography. Potential major cardiac embolic sources (e.g. atrial fibrillation, thrombi of left ventricle/atrium, vegetation, myxoma, dilated cardiomyopathy) have a causal relationship to embolism. Other changes with no certain causal relationship are regarded as potential minor cardiac embolic sources (e.g. atrial septal aneurysm, patent foramen ovale, mitral annular calcification, mitral valve prolapse, protruding atheroma of the aorta). We compared the prevalences of major and minor potential cardiac embolic sources in a stroke population with that in controls. One hundred and twenty-one patients with first-ever stroke were compared with 68 randomly selected controls. All subjects underwent magnetic resonance imaging of the brain, carotid ultrasound and transthoracic/transoesophageal echocardiography. The patients were slightly older (mean age 70.7 +/- 10.3 years) than the controls (65.5 +/- 15.5 years) (p < 0.05). Potential major cardiac embolic sources were found in 27% of the patients and in 4% of the controls (p < 0.001). The most common major potential embolic source was atrial fibrillation, detected in 22/121 patients. Fifteen of these also had spontaneous echocontrast in the left atrium. Eleven left atrial thrombi were found (four of these patients had atrial fibrillation and seven had sinus rhythm). A history of heart disease was more common in patients with a potential major cardiac embolic source or a carotid artery stenosis (77%) than in those patients without (44%) (p < 0.01). After excluding subjects with a major potential cardiac embolic source and/or carotid artery stenosis, no differences in the prevalence of minor potential cardiac embolic sources were found between patients (55%) and control subjects (47%) (p = NS). Even when subjects without a major potential cardiac embolic source or a carotid artery stenosis were categorized into three age groups (35-54, 55-74 and > 74 years) the prevalence of potential minor cardiac embolic sources did not differ between patients and controls. To conclude, major potential cardiac embolic sources are more common in an older population with first-ever stroke than in a comparable control group. However, potential minor cardiac embolic sources did not differ in prevalence in the patients compared with controls. Certain changes (e.g. atrial septal aneurysm) might have a potential embolic role in younger stroke patients but in our study no difference was found between older stroke patients and controls.

Abstract
Degree of connection to the criminal underworld was the basis for typologic research on 698 male drug abusers; interviews as well as official records were used. Four types were distinguished: The addicted criminals seemed to resemble the groups dominant in Sweden from the 1950s to the 1970s. An early crime debut and criminal offenses in youthful years characterized their deviant careers. Drugs and criminal activities coexisted with an often very high intake of alcohol and the most difficult childhood and adolescence conditions compared to the other types. The criminal addicts had fewer recorded acts of juvenile delinquency. Their drug abuse was severe and occurred later in life, as criminality did, but tended to accelerate very rapidly. Their subcultural affiliation was probably as strong as that of the addicted criminals. A large group called low-crime addicts had a weak subgroup affiliation. The "normal" abuse pattern, with cannabis as the first substance used and a gradual shift to more severe opioid and CNS stimulant abuse, was most true of this type. Probably the drug abuse played a role in the development of the criminal pattern. Emotionally unstable addicts with little or no criminality had the best education, job situation and social relations. Multiple drug abuse and abuse of legal drugs were common. Mental ill-health was characteristic for this group. The results show that drug abusers in Sweden cannot be seen as a homogeneous group of individuals, that they do not commit crimes only in order to finance their habit, and that the history of narcotics use in Sweden, with its strong connection to a criminal subculture, is highly relevant to this sample.
