B 48 and apo-B 100 when the cells were cultured directly on the plastic dishes compared to cultures on collagen. Although the amount of labeled apo-B was lower and secretion of apoB was inhibited by collagen, no obvious effect on the proportion of newly synthesized apo-B 48 and apo-B 100 was found. The proportion of apo-B 48 in the medium in the present study is lower than that in the cells. This discrepancy is explained by the relative retention of apo-B 48 intracellularly. It has been shown that the proportion of apo-B 48 in the medium could be increased to the intracellular level by chasing the labeled cells for another 4 h with an excess of unlabeled methionine 14 ; . However, the differences in the proportions of apo-B 48 between different hormonal treatments were not dependent on whether there was a chase period 14 ; . The effects of IGF-I may be dependent on the interaction between IGF-I and its binding proteins. Thus, it has been suggested that IGF-binding proteins may modulate the effects of IGF-I in both a stimulatory and an inhibitory way 40 ; . IGF-I induces IGF-binding protein-3, but GH is required for the induction of the acid-labile protein of the 150~kilodalton complex. This complex is present in GH-treated rats, but not in IGF-I-treated rats 1, 40 ; . The possibility that concomitant GH treatment is a prerequisite for the effects of IGF-I has been tested in dwarf rats given either IGF-I alone or in combination with GH Oscarsson, J., R. G. Clark, A. Sjoberg, S.-O. Olofsson, and S. Eden, unpublished observation ; . There was no further effect of IGF-I in GH-treated dwarf rats on serum lipoproteins, suggesting that the lack of a GH-like effect of IGF-I treatment was not due to low levels of the 150kilodalton complex. The present results are in contrast to the observations that IGF-I reduced triglyceride levels in man 18 ; , but in accordance with the results obtained in IGF-I-treated transgenic mice, which had higher serum triglyceride levels than normal mice and GH transgenic mice 19 ; . However, the increased serum apo-B levels as a result of IGF-I treatment is a novel finding. The mechanism for these effects of IGF-I is unclear. We did not find any major effects of IGF-I on apo-B or triglyceride secretion from cultured hepatocytes. As the liver is the major source of circulating apo-B 41 ; , the most plausible explanation for the effects observed is that IGF-I inhibits the removal of triglyceride-rich apo-B-containing lipoproteins. An increased serum concentration of apo-B could also be due to a decreased proportion of secreted apo-B 48, because apoB 48 has a higher rate of turnover than apo-B 100 42 ; . However, no obvious effect of IGF-I on the proportion of newly synthesized apo-B 48 or apo-B 100 was observed. Thus, in contrast to GH treatment 14 ; , IGF-I treatment of hypophysectomized rats does not affect the proportion of newly synthesized apo-B 48 and apo-B 100. The hepatic secretion of apo-B 100, therefore, predominates after IGF-I treatment. In diabetic rats, in which similar changes in serum concentrations of apo-B and triglycerides have been observed 39, 43 ; , it has been shown that the removal of very low density lipoprotein is impaired 44 ; . These changes are similar to.

KIJTAWORNRAT ET AL. Experimental protocol. Animals were anesthetized with a combination of ketamine and xylazine 35 and 5 mg kg im ; . The right marginal ear vein was cannulated for intravenous administration of drug. Rabbits were placed in dorsal recumbency. The right and left thoracic limb electrodes were attached to the right and left hemithoraces, the electrocardiograph was switched to limb lead I, and a bipolar transthoracic ECG was obtained on a Biopac MP100 Data Acquisition Unit Biopac Systems, Inc., Santa Barbara, CA ; . The high-pass filter was set at 0.01 Hz and the low-pass filter at 1 kHz, and signals were digitally sampled at a frequency of 2 kHz. Anesthesia was maintained as necessary by administration of further doses of ketamine and xylazine 20 and 3 mg kg im, respectively ; . All rabbits were allowed at least 10 min stabilization before starting any drug infusion. Drugs were selected because they are either known torsadogens or known not to produce TdP. Torsadogens were selected from groups possessing varied pharmacological properties e.g., class IA, class III, prokinetic ; . All drugs were infused intravenously over a period of 10 min, with a 20-min interval between doses. The infusion was stopped as soon as TdP started. The drugs tested in this study were amiodarone 3, 10, and 30 mg kg; control group n 6, myocardial failure group n 4 ; , cisapride 0.1, 0.25, 0.50 mg kg; control group n 4, myocardial failure group n 4 ; , clofilium 0.1, 0.2, 0.4 mg kg; control group n 6, myocardial failure group n 5 ; , dofetilide 0.005, 0.01, 0.02, and 0.04 mg kg; control group n 10, myocardial failure group n 7 ; , quinidine 3, 10, and 30 mg kg; control group n 6, myocardial failure group n 4 ; , and verapamil 0.25, 0.50, and 1.0 mg kg; control group n 6, myocardial failure group n 4 ; . The doses of each drug were chosen according to those used in previously published rabbit studies by other research groups Batey and Coker, 2002; Carlsson et al., 1997; Farkas et al., 2002; Lu et al., 2000 ; . RR and QT intervals were measured 15 min after each drug dose had been infused. The QT interval was corrected for heart rate by dividing the QT interval by the cube root of the preceding RR interval Fridericia, 1920 ; . Measurements were made from at least 12 consecutive cardiac cycles, and the average was used. The ECG intervals were measured in beats that originated from the sinoatrial node; however, at some points ECG intervals could not be obtained from all animals because of marked arrhythmia. The QT interval was defined as the time between the first deviation from the isoelectric line during the PR interval until the end of the T wave. TdP was defined as a polymorphic ventricular tachycardia where clear twisting of the QRS complexes around the isoelectric axis was seen. Drugs. Amiodarone hydrochloride Sicor Pharmaceuticals, Irvine, CA ; was prepared by diluting commercial amiodarone for injection 450 mg amiodarone in 9 ml diluent ; with 9 ml of 0.9% NaCl to a final concentration of 25 mg ml. Cisapride Medisca Inc., Plattsburgh, NY ; was dissolved in 10% acetic acid to form a stock concentration of 10 mg ml. Clofilium tosylate Sigma, St Louis, MO ; was dissolved in 0.9% NaCl solution to form a stock concentration of 3 mg ml. Dofetilide Pfizer, Groton, CT ; was dissolved in 0.9% NaCl with the help of 0.1M hydrochloric acid to form a stock concentration of 0.1 mg ml. Quinidine hydrochloride Sigma ; stock concentration of 30 mg ml ; and verapamil hydrochloride Sigma ; stock concentration of 2 mg ml ; were also dissolved in 0.9% NaCl. Analyses of dosing solutions were not performed; however, each drug was injected within 60 min of preparation. Statistics. Values are expressed as mean SEM. Fisher's exact tests were used to compare the incidence of TdP between groups. A probability value of p 0.05 was considered to be significant.

Part I contains an introduction to the thesis, including an explanation of the objective and methodological issues. I also provide an overview of the relevant legal research with respect to Saami and environmental law. The objective of this thesis has two parts, where the first in brief aims to analyse the interface between aspects of the Saami law and environmental natural resources legislation. The second part, which is a development of the first, aims to analyse and discuss ways in which the legislation may contribute to a sustainable use of the Swedish reindeer herding area. Hence, although I provide a detailed comparison of the laws of Aotearoa New Zealand, Canada and Sweden, the focus lies on Swedish law. The analysis of New Zealand and Canadian law is, nevertheless, an aid to both parts of the objective. However, the very beginning of this part commences with concise background information regarding all three countries, providing for a better understanding of the complex issues with respect to the different legal settings. Lastly, Part I contains a chapter that discusses the main characteristics of the three legal systems to provide essential information regarding certain key features, which will enhance the understanding of the analysis of the laws in Part II.
Increase in tail currents with slow deactivation kinetics. BEAG gave rise to delayed rectifierlike outward currents with activation kinetics strongly dependent on the holding potential and an extremely fast current deactivation at more hyperpolarized membrane potentials Fig 1C and D ; . Overall, the biophysical properties of BEAG K channels were identical to those described for mouse and rat eag channels Fig 1C and 1D ; .16, 17 At the protein level, BEAG is 96% identical to both rat and mouse eag. When compared with HERG, BEAG diverges considerably and shows only 50% identity with HERG in the hydrophobic core region S1-S6 of the channel proteins.18 To analyze the high-affinity binding site of dofetilide in HERG K channels, we took advantage of the fact that BEAG is 100-fold less sensitive to dofetilide than HERG. IC50 values were measured in two-microelectrode whole-cell recordings with a prepulse protocol to accelerate the onset of block see "Materials and Methods" ; . Fig 2A shows HERG currents recorded at 0 mV during perfusion of different dofetilide concentrations. Current amplitudes became more and more reduced with increasing drug concentrations. Current activation and deactivation kinetics, however, were not modified. To test drug effects on current inactivation, we isolated the inactivation process with the following voltageclamp protocol: cells were held at 40 mV, hyperpolarized for 20 milliseconds to 100 mV to remove any inactivation accumulated at holding potential, and finally depolarized to 0 mV. The voltage step to 0 mV elicited a rapidly decaying outward current, which reflects the highly synchronized inactivation of HERG channels available in a particular cell inset, Fig 2A ; . Time constants characterizing the inactivation process were analyzed by fitting monoexponential functions to the decaying outward currents. At membrane potentials of 40, 20, 0, and 20 mV, time constants were 13.5 0.4, 12.1 and 5.7 0.4 milliseconds n 5 ; . With and dok.

Macula densa. Besides being present in a larger physical region of the TAL, NKCC2a also appeared to have the largest Na transport capacity and would, therefore, be the predominant contributor to Na-K-Cl reabsorption in TAL 8 ; . These cotransporters, in interplay with the basolaterally located chloride channel complex CLC-Kb Barttin ; and the Na K-ATPase, transport NaCl from the lumen back to the blood compartment. Another key component in this system is the apical inwardly rectifying ATP-sensitive K channel, designated ROMK, which ensures adequate presence of luminal K critical for continuous Na-K-Cl uptake by NKCC2 and generates the lumen-positive electrical gradient driving paracellular Ca2 and Mg2 reabsorption 9, 10 ; . So far, mutations in NKCC2, ROMK, ClC-Kb, and Barttin have been linked to the four types of BS that are currently distinguished. Types I and II BS correspond to mutations in NKCC2 2 ; and ROMK 3, 11 ; , respectively. These two variants are life-threatening disorders in which both the hypokalemic alkalosis as well as profound systemic symptoms are present at birth 1214 ; . Some of these symptoms already arise in utero, where fetal polyuria can cause polyhydramnios between 24 and 30 wk of gestation followed typically by premature delivery. Affected neonates have severe salt wasting and hyposthenuria as well as hyperprostaglandinuria and failure to and doral.
