Efficacy analyses were based on the full analysis set corresponding to the intentto-treat population ; , which comprised all randomised patients who took doubleblind study product and had at least one valid post-baseline assessment of the primary efficacy measure. Safety analyses were based on the set of all patients treated, which included all patients who took at least one dose of double-blind study product. A minimum of 135 patients per treatment arm was required to reach a power of 90% to detect a significant difference between treatment groups in mean change from baseline to final assessment in LSAS total score at the 5% significance level. A general linear model for analysis of covariance ANCOVA ; was applied to the primary and secondary efficacy measures with factors for treatment group and centres all centres with fewer than four patients were collapsed into one collective centre ; , and with baseline LSAS total score as a covariate. The final CGIS and CGII scores were also analysed using the non-parametric CochranMantelHaenszel mean score statistics. Between-group comparisons of the proportion of responders CGII score of 1 or treatment were performed using chi-squared and Fisher's exact tests. Descriptive statistics were used for absolute values and mean changes from baseline in laboratory values, ECG parameters, vital signs and body weight. All statistical tests were two-sided and were carried out at the 5% level of significance.

Obtain one variety where you live. However, if at all possible, try to feed mixed grass hay or provide two or more individual types. Grass hays are rich in nutrients but provide the lower energy diet appropriate for a house rabbit. These are the healthiest hays to feed. If you have a choice, choose sun-dried hay that has retained more of its nutrients than commercially dried hay. Do not feed straw. Straw is devoid of most nutrients and although it is not harmful in small amounts, it will lead to serious nutritional deficiencies if it is major part of the rabbit diet. Legume hays are made from alfalfa, clover, peas, beans or peanuts. These hays are loaded with nutrients but have more calories, calcium and protein than a house rabbit needs. Feeding only legume hays may lead to GI disorders and obesity and for this reason we do not recommend feeding these hays. If you mix legume hay with grass hay, the rabbit may only pick out the calorie-rich legume hay and thus overload itself with calories, thus we do not recommend mixing grass and legume hay. If you live in an area where only legume hay is available it is preferable to use it rather then no hay at all. However you may wish to limit the amount of hay if your pet experiences excessive weight gain or GI problems and procarbazine.

Cooperation between the institutions should enhance the mutual support by learning from each other, by exchanging experiences, and by regular mutual reflections on what we can do to counteract the 'less interest among students' and the 'less interest among the academic and political authorities' and also on what we can learn from more successful or from less successful partners. The scope of CHERNE is not limited and any activity related to higher education in radiological and or nuclear engineering can be proposed. CHERNE activities will be organised mostly for students of members, mainly at Master level. They should include at least a one-week 2 ECTS module. It's necessary to include practical training in activities for students, including when possible an access to large facilities. Teaching modules are clearly seen as a possible kind of activity, but other types of cooperation may be also developed such as material for modules conveniently adapted in each university, e-learning, etc. The language used in CHERNE activities is English. The CHERNE activities will be organised at no cost, or very low fee, for students coming from other partner institutions. The organising partner will find and propose cheap accommodation for the students coming from abroad. When possible, the organisation of CHERNE activities will be included in ERASMUS exchanges. Therefore, the partners are encouraged to sign bilateral ERASMUS agreements. Research collaborations are not the main goal of the network. However, they are quite naturally developed as a consequence of the frequent exchanges for educational cooperation. [3, 4, 5].

Discussion We found remarkably low efficacy rates for lidocaine in combination with quinidine, procainamide or encainide, using prevention of VT induction at electrophysiologic study as the indicator of drug efficacy. The efficacy rates for propranolol combinations were somewhat higher, but most of these patients had not been proven to be unresponsive to propranolol alone. Acute efficacy rates for single drug trials in our laboratory are 13% for lidocaine, 20% for quindine, 19% for procainamide, 9% for encainide, 27% for propranolol, 1 for amiodarone, 10% for lorcainide and 12% for other agents.13 The acute efficacy rates for propranolol and propantheline.
Stability at Low pH All surface bonded chemistries belonging to the BETASIL family are highly stable under chemical attack. Hydrolysis of the silane ligand can occur under acidic conditions, resulting in a loss of retention and or selectivity. The effect becomes more severe as ligand chain length is reduced, as is observed for the BETASIL C1 phase. Wettable stationary phases such as the BETASIL Cyano packing can also show slightly less resistance to chemical attack, and consequently are recommended only for use between pH 2 and 8. In general, BETASIL packings show superior stability to many other packings. Figure 2 shows BETASIL phases subjected to 25, 000 column volumes of aggressive mobile phase at pH 1.8 and 50C. The BETASIL C18 phase exhibits virtually no change in retention for the analysis of a sensitive drug mixture. Base Deactivated for Better Peak Shape with Basic Compounds All BETASIL packings are base deactivated and show excellent peak shape for basic compounds. Figure 3 shows the analysis of a procainamide test mixture, a mixture that would typically have given rise to broad tailing peaks for the more basic compounds on traditional C18 silicas prepared on a Type A silica. In terms of silanol activity, the BETASIL packing is similar to other Type B silicabased phases such as BetaBasic and BetaMax Neutral phases. Phase Collapse Phenomenon Mobile phases that contain a high proportion of water often are employed to retain highly polar compounds when using RP-HPLC. Many C18 columns will show a reversible loss of retention when exposed to highly aqueous mobile phase. The rate and degree of retention loss can vary greatly among different columns. A common explanation for this retention loss is that the hydrophobic alkyl chains of the stationary phase are not wettable and appear to "fold" down on the silica surface to avoid a highly aqueous, hydrophilic mobile phase Figure 4 and procainamide.

Background. Use-dependent effects of antiarrhythmic drugs on phase 0 sodium current result in rate-dependent conduction slowing with important potential clinical consequences. The purpose of the present study was to determine whether state-dependent interactions of procainamide with sodium channels can be analyzed based on conduction changes in vivo. Methods and Results. Procainamide infusions were used to produce stable drug concentrations causing 25% conduction slowing at a basic cycle length BCL ; of 300 msec in morphine chloralose-anesthetized dogs with formalin-induced atrioventricular block. Computer-based epicardial activation mapping was applied to assess the time course and pattern of conduction over a wide range of BCLs before and after drug administration. Action potential duration was measured from recordings of monophasic action potentials. The onset and steady-state values of fractional sodium channel block estimated from conduction changes were fitted to equations obtained from a stepwise exponential analysis. The rate constant for the onset of block A * ; decreased, as predicted, with decreasing cycle length. The slope of the relation between A * and recovery time at each BCL averaged 0.290.03 sec-', resulting in a calculated recovery time constant 3.4 seconds ; similar to values previously obtained by direct measurement. Estimates of binding and unbinding rate constants for the sodium channel during the action potential plateau and after repolarization were of the same order as previous results obtained using microelectrode methods in vitro. Conclusions. Use-dependent conduction changes produced by procainamide in vivo closely follow the predictions of mathematical models of drug-channel interactions, and underlying kinetic interactions with the sodium channel inferred from conduction changes agree with previous, more direct observations. These results support the relevance of basic concepts about antiarrhythmic drug actions on sodium channels for understanding drug effects on conduction in vivo and advance analytical tools that can be used to explore the latter in humans.

AERPAP correlates best with a history of ventricular fibrillation, 9 and the correlation of AERPAP and SRRPE remains controversial.9 11-14 The purpose of the present investigation was twofold: first, to test the hypothesis that loss of preexcitation in sinus rhythm with procainamide infusion reliably predicts SRRPE, and second, to reexamine the relationship between AERPAP and SRRPE and thus determine whether AERPAP can be used as a reliable guide for SRRPE.
