    Notes: Abstract: Protein tyrosine kinases that are known to have major roles in the control of cell growth and transformation are abundant and have numerous phosphoprotein substrates in the adult CNS. Although less well characterized than serine/threonine kinases, tyrosine kinases are also concentrated in the synapse. The effect of genistein, a selective inhibitor of tyrosine kinase activity, was examined on the in vitro release of endogenous dopamine (DA) from superfused mouse striatal slices. Fractional release of DA was significantly increased over basal release levels by genistein (100 and 200 µM). The effect was concentration dependent and rapidly reversible on washout of the kinase inhibitor. No significant change from basal release levels was observed with two structural analogues of genistein that do not inhibit tyrosine kinase activity at the same concentration. We have previously described alterations in basal and evoked DA release from the striatum of the weaver (wv/wv) mutant mouse, and genotypic differences in fractional release were also observed with genistein stimulation. The total evoked release was 25–50% greater from the wv/wv striatum. These results suggest a modulatory role for tyrosine kinase activity in neurotransmitter release and perhaps an alteration of kinase-regulated mechanisms in the DA-deficient wv/wv striatum.

    Notes: Abstract: The weaver mutant mouse (wv/wv) has an ∼70% loss of nigrostriatal dopamine (DA) neurons, but the fractional DA release evoked by amphetamine (but not a high potassium level) has been shown to be greater from striatal slices of the weaver compared with +/+ mice. In the present work we tested the hypothesis that fractional DA release from weaver striatum would be greater when release was mediated by the DA transporter. Serotonin (5-HT)-stimulated fractional DA release was greater from weaver than from +/+ striatum. The release evoked by 5-HT in the presence of 10 µM nomifensine (an antagonist of the DA transporter) was less than in its absence, but the difference between weaver and +/+ striatum remained. In the presence of nomifensine, 1-(m-chlorophenyl)biguanide, classified as a 5-HT3 agonist, also induced a greater fractional release from weaver compared with +/+ striatum. When veratridine was used at a low concentration (1 µM), the fractional evoked release of DA was higher from the weaver in the presence and absence of nomifensine. These findings suggest that the reason for the difference in the responsiveness of the two genotypes to these release-inducing agents is not related to DA transporter function.

    Notes: : This randomized, double-blind, multicentre study compared lansoprazole with placebo for symptomatic relief of patients with non-erosive gastro-oesophageal reflux disease (GERD).〈section xml:id="abs1-2"〉〈title type="main"〉Methods: 214 patients with symptomatic, non-erosive GERD (moderate to severe daytime and/or night-time heartburn greater than half the days over the past 6 months and during the 7- to 10-day pre-treatment period) were randomized to either lansoprazole 15 mg or lansoprazole 30 mg, or placebo o.d. for 8 weeks.〈section xml:id="abs1-3"〉〈title type="main"〉Results: Daily diary data indicated that on the first treatment day a statistically significantly smaller percentage of lansoprazole patients reported daytime and night-time heartburn and antacid usage, compared with placebo patients. Lansoprazole patients also reported statistically significant less severe daytime and night-time heartburn on the first treatment day. During 0–4, 4–8, and 0–8 weeks of therapy, a statistically significant smaller percentage of days and nights with heartburn, less severe daytime and night-time heartburn, and less antacid usage were observed in the lansoprazole group compared to the placebo group. The percentages of patients with adverse reactions were similar in the lansoprazole and placebo groups.〈section xml:id="abs1-4"〉〈title type="main"〉Conclusions: The results of this study demonstrate that lansoprazole is an appropriate therapy for patients with symptomatic non-erosive GERD.

    Notes: Although recent studies suggest that gastro-oesophageal reflux disease may frequently contribute to ear, nose and throat and respiratory diseases, the cause-and-effect relationship is far from proven. The review will address this controversial topic emphasizing recent literature raising concerns about the credibility of this association and our tests to make this diagnosis. The author believes these extraoesophageal symptoms suspected to be secondary to gastro-oesophageal reflux disease are an unresolved issue, but selective use of aggressive proton-pump inhibitor therapeutic trials may help to resolve this problem in our individual patients.

    Notes: Heartburn is a normal consequence of pregnancy. The predominant aetiology is a decrease in lower oesophageal sphincter pressure caused by female sex hormones, especially progesterone. Serious reflux complications during pregnancy are rare; hence upper endoscopy and other diagnostic tests are infrequently needed. Gastro-oesophageal reflux disease during pregnancy should be managed with a step-up algorithm beginning with lifestyle modifications and dietary changes. Antacids or sucralfate are considered the first-line drug therapy. If symptoms persist, any of the histamine2-receptor antagonists can be used. Proton pump inhibitors are reserved for women with intractable symptoms or complicated reflux disease. All but omeprazole are FDA category B drugs during pregnancy. Most drugs are excreted in breast milk. Of systemic agents, only the histamine2-receptor antagonists, with the exception of nizatidine, are safe to use during lactation.

    Description / Table of Contents: Zusammenfassung. In einem 2,5 jährigen Zeitraum wurden 55 Patienten mit einer frischen Achillessehnenruptur (ASR) nach definierten sonographischen Kriterien operativ und funktionell konservativ behandelt. Durchschnittlich 2,4 Jahre später konnten von 51 Patienten (operative Gruppe = 28 Patienten, konservative Gruppe = 23 Patienten) erneut klinische, funktionelle sowie isokinetische Daten der eingelenkigen Plantarflexoren erfaßt werden. Während in der operativen Gruppe insgesamt bei 10,6 % Wundheilungsstörungen mit spontanem Heilungsverlauf auftraten, betrug die Rerupturrate in der konservativen Gruppe 13 %. Die Incidenz an Achillodynien war zum Nachuntersuchungszeitpunkt in der nicht operativen Gruppe deutlich höher (p = 0,019). Durch die Cybextestung wurden durchschnittliche Kraftdefizite in der operativen Gruppe von 13,7 % und nach funktionell konservativer Behandlung von 24,7 % (p = 0,012) festgestellt. Während die Adaptationsnaht i. d. R. zum Erfolg führt, ist die Indikation zur konservativen Therapie der ASR von der Sehnendiastase, dem Aktivitätswunsch und der Kooperation abhängig.
    Notes: Summary. According to sonographic criteria, 55 patients underwent surgical treatment with mobilisation in a lower leg plaster or conservative treatment with early mobilisation in heel pad (3 cm) shoes when an acute Achilles tendon rupture (ATR) was diagnosed. The follow-up period in 51 patients was 2.4 years (operated group = 28 patients, conservative group = 23 patients) with clinical examination and testing of isokinetic muscle strength in knee joint flexion. After surgical treatment, minor wound infections occurred in 10.6 %. Reruptures occurred in 13 % of the conservative group. Following conservative treatment, the rate of stress-related achillodynia was significantly higher (P = 0.019). In the operated group mean isokinetic muscle strength was 13.7 % lower than in the uninvolved leg and decreased significantly with non-operative treatment to 75.3 % (P = 0.012). We recommend surgical treatment of acute ATR. The indications for conservative treatment depend on the extent of the rupture (measured by ultrasound in the equinus position), the desired level of daily activity and the patient's degree of compliance.

    Notes: Abstract In 1991, field experiments on loess (with winter wheat) and sandy soils (with summer barley) were conducted to study N dynamics in the microbial biomass and non-exchangeable NH inf4 sup+ . The measurements showed a mass change in microbial N, with a maximum increase of 100 kg N ha-1 30 cm-1 from March to July in the loess soil, and a change for only 1 month (May) in the sandy soil. Plots treated with conventional levels of N fertilizer (213 kg N ha-1 on a loess soil to winter wheat and 130 kg ha-1 on the sandy soil to summer barley), reduced levels of N (83% and 62% of the conventional N application), or no N showed no consistent fertilizer N effect on microbial biomass N. From March to July, non-exchangeable NH inf4 sup+ in loess soils under winter wheat decreased by 110 kg N ha-1 30 cm-1 in conventionally fertilized plots and by 200 kg N ha-1 30 cm-1 in a plot with no N fertilizer. After harvest, the pool of non-exchangeable NH inf4 sup+ increased due to increasing mineral N concentrations in the soil.
