    Abstract This study's aim was to elucidate health-care staff experience of working on a locked acute psychiatric ward. In many countries changes in health care has contributed to fewer beds available in inpatient care, and a concentration of patients with severe psychiatric conditions. This implies a changing work environment in acute psychiatric care. Qualitative interviews with health-care staff (n= 10) were carried out on a ward for patients with affective disorder and eating disorder in a Swedish hospital. Qualitative content analysis was used. Four themes were identified from the data: 'undergoing changes in care delivery', 'feeling a need for security and control', 'managing the demands at work' and 'feeling a sense of responsibility'. This study adds to earlier research into how a sense of responsibility can place a significant burden on health-care staff working on a locked psychiatric ward and also contribute to increased control of patients. This study also shows that relationships and power structures among health-care staff need to be addressed when organizational changes are made in care delivery. Further research is needed to reach a comprehensive understanding of care on locked acute psychiatric wards, including a development of nursing and medicine as knowledge domains in one common context.

    Abstract Flunixin is determined in equine plasma by liquid chromatography on LiChrosorb RP-18 with 70% methanol in phosphate buffer pH 3.1 as the eluent, with detection at 284 nm. Plasma is deproteinized with methanol and the supernatant is then injected directly into the system. With a short pre-column (5 x 3 mm i.d.), which is replaced after 25-40 injections of sample, 420 plasma samples could be analysed on one analytical column. The detection limit in plasma is 0.30 micromol/l (89 ng/ml) and the method can be used in pharmacokinetic studies.

    Abstract Patients who are involuntary admitted to psychiatric care are extremely vulnerable as a consequence of the control from others, and of the personal limitations due to a psychiatric disease that can influence their own control of their lives. This group of patients are seldom asked about their experiences of being cared for. In this study five involuntary hospitalized psychiatric patients narrated their experience of being subjected to involuntary psychiatric care. The aim of the study was to obtain a deeper understanding of this experience. The interview text was analysed by means of a phenomenological hermeneutic method. The result of the analysis gave a complex picture of both support and violation. On the one hand experiences of not being seen or heard, of loss of liberty and of violation of integrity were found. On the other hand, there were experiences of respect and caring and opportunities to take responsibility for oneself were offered. Being treated involuntarily in psychiatric care was interpreted as a balancing act between good opportunities and great losses.

    Abstract This focused ethnographic study aims at describing encounters in the healthcare environment on a locked psychiatric ward. It was carried out in Sweden on an acute psychiatric ward for patients with affective and eating disorders. Data were collected through participant observations and informal interviews, and analysed by qualitative content analysis. The result shows that the healthcare environment on this locked psychiatric ward offered a space for encounters between people, in a continuum from professional care to private meetings and social events. It included joy and friendship as well as unintentional insights into other patients' suffering. The characteristics of the encounters formed three themes: the caring relationship, the uncaring relationship and the unrecognized relationship. The caring and the uncaring relationship concerned relationships between staff and patients or their next of kin. These revealed contrasting qualities such as respect and flexibility as well as lack of respect and mistrust. The unrecognized relationship theme visualized the patients' relationships with each other and included both supportive and intrusive elements that were probably significant for the outcome of care. The unrecognized relationship contributes with new knowledge about conditions for patients in inpatient care, and indicates that the patients' relationships with each other merit greater attention.

    Abstract Two metabolites of meclofenamic acid have been isolated from equine urine. Both metabolites are found to be monohydroxylated forms of meclofenamic acid by gas chromatography-mass spectrometry after extractive alkylation. The parent drug and the metabolites are separated by reversed-phase liquid chromatography on a Spherisorb ODS column, using methanol-phosphate buffer eluents and UV detection at 280 nm. The structure of the metabolites is discussed on the basis of LC, TLC and GC-MS data.

    Abstract A high-performance liquid chromatography method was developed for determination of flunixin in bovine plasma. The extraction procedure was easily performed and made it possible to detect low concentrations of flunixin with high accuracy. The limit of quantitation was 7 ng/ml (relative standard deviation = 18% n = 10). The analytic method permits processing of 60 samples/d. Flunixin, as well as the internal standard (diclofenac sodium), belong to the group of nonsteroidal anti-inflammatory drugs, which are known to have a high degree of binding to plasma proteins. Therefore, an evaluation of several buffer systems was undertaken to optimize analytic conditions. Cattle were given 2.2 mg of flunixin melgumine/kg of body weight. In experiment 1, single injections were administered IV to 1 cow and IV and IM to 1 heifer (7 days apart), and pharmacokinetic variables were calculated. The IV data were best described by a two-compartment model. The half-life after single IV or IM administration was around 4.0 hours. In experiment 2, the decreasing flunixin concentration was determined after the last of either 4 IM injections daily (n = 3 cows) or 2 IM injections daily (n = 3 cows) administered during a 14-day postpartum period. The half-life, determined between 48 and 96 hours after the last dose, was approximately 26 hours in both groups, and flunixin could be detected in plasma up to 8 days, on average. The protein binding of flunixin was studied, using the method of equilibrium dialysis.(ABSTRACT TRUNCATED AT 250 WORDS)

    Abstract Chloroplast carbonic anhydrase from Pisum sativum has been studied to elucidate the catalytic mechanism and to test if the mechanism proposed for human carbonic anhydrase II is also valid for pea carbonic anhydrase. The catalytic activity was found to depend on the chemical nature of the buffer. Barbital buffer gives the highest turnover number at infinite buffer concentration and the lowest Km value with respect to the buffer, while the kinetic parameters obtained in the imidazole-type buffer, 1-methylimidazole, do not differ from those obtained using the biological-type buffer Mops. The anion inhibition of CO2 hydration was investigated using SCN- at pH 6-9. The binding of the anion was found to be pH dependent with the strongest interaction at low pH. We obtained an uncompetitive inhibition pattern at high pH and noncompetitive inhibition patterns at pH 7 and low pH. The catalytic mechanism was further tested by measurements of the solvent hydrogen isotope effects on the kinetic parameters for CO2 hydration. The observed effects were comparatively small with a kcat value of approximately 2 irrespective of the pH. The effect on kcat/Km and on Km changes when going from high pH to pH 7 and low pH. At high pH, the solvent isotope effect in Km is at least 3, giving a value below 1 for kcat/Km, while at pH 7 and low pH the major effect is found in kcat/Km with values of 2.6 and 2.9. The dependence of the CO2-hydration activity on the buffer concentration is in agreement with a ping-pong mechanism with buffer acting as a second substrate. This is analogous to the behaviour of human carbonic anhydrase II. The inhibition patterns and the observed isotope effects at high pH can also be explained within the framework of the catalytic mechanism for human carbonic anhydrase II, with a rate-determining and buffer-dependent part. The results are consistent with a mechanism involving a proton transfer that contributes to rate limitation. However, the isotope effects found at pH 7 and low pH indicate that some part of the mechanism has changed. Moreover, we cannot decide whether the mechanism for pea carbonic anhydrase involves an internal proton-shuttle group, or if the buffer molecule acts in a direct proton transfer from the zinc-coordinated water.

    Abstract Chloroplast carbonic anhydrase from Pisum sativum has been isolated. The kinetic properties of the enzyme have been studied and comparisons to the well characterised human carbonic anhydrase II made. Pea carbonic anhydrase was found to be dependent on a reducing agent in order to retain the catalytic activity. Oxidised, inactive, enzyme could be activated by the addition of a SH-agent. However, such activation gave only 60% of the activity of an enzyme kept in a reduced state all the time. The kinetics of CO2 hydration show an increase in kcat as well as in kcat/Km with pH, but the pH profile does not follow a simple titration curve. The pH dependence is more complicated and it seems as if there are several titratable groups affecting the activity. At pH 9 we obtain a turnover number of 4 x 10(5) s-1 and a kcat/Km value of 1.8 x 10(8) M-1 s-1 with reference to the subunit. We also find that the enzyme needs high concentrations of buffer to work at a maximal rate. Apparent Km values with respect to the total buffer concentration are found between 52-185 mM at neutral and high pH. At low pH the situation is complex with deviations from Michaelis-Menten kinetics. Chloroplast carbonic anhydrase from higher plants have been reported to have primary structures that are completely different from the enzyme from animals. In addition, we find the circular dichroic spectrum of pea carbonic anhydrase to be well distinguished from that of human carbonic anhydrase II. Despite those structural differences the kinetic parameters indicate that pea carbonic anhydrase is equally efficient as human carbonic anhydrase II in catalysing the hydration of CO2. However, the mechanism for proton transfer from the active site to the surrounding medium seems to differ between the two enzymes.

Flunixin was found to have a high degree of protein binding (ie, 99.4 +/- 0.2%) at a flunixin concentration in plasma of 3 to micrograms/ml. Differences in protein binding between cattle were not found.

    Abstract The chloroplast transit peptide (cTP) of pea carbonic anhydrase was shown to be processed at two different sites, giving protein subunits of two sizes. The cleavage sites were identified and found to be localized immediately before and after a highly charged part, containing 8 acidic and 6 basic residues, of the cTP. Properties of pea carbonic anhydrase produced in Escherichia coli show that folding, oligomerization and catalytic activity do not depend on the presence of the acidic part or the rest of the cTP. The pattern of processing of the cTP in E. coli indicates that cleavage at site I is specific for a chloroplastic stromal peptidase and that cleavage at site I prevents processing at site II.
