161. Gastrointestinal Replacement Solution Full Text available with Trip Pro

Gastrointestinal Replacement Solution The mean sodium concentration of 61 gastrointestinal aspirations in peritonitis was 103 mEq/l. (S.D. 16.66), of 16 aspirations in vagotomy 88 mEq/l. (S.D. 19.49), of 12 aspirations in perforated duodenal ulcer 81 mEq/l. (S.D. 19.49), and of 15 aspirations in intestinal obstruction 89 mEq/l. (S.D. 19.49). The mean potassium concentrations were 9, 9.9, 13, and 8.8 mEq/l. respectively, and the mean chloride concentrations 122, 131, 125, and 112 mEq/l (...) . respectively. It is suggested that a gastrointestinal replacement solution should contain 100 mEq of sodium, 12 mEq of potassium, and 122 mEq of chloride per litre; 50 g. of dextrose or 100 g. of fructose may be added to provide energy.

162. Effects of replacing medium sodium by choline, caesium, or rubidium, on water and ion contents of renal cortical slices Full Text available with Trip Pro

Effects of replacing medium sodium by choline, caesium, or rubidium, on water and ion contents of renal cortical slices 1. Renal cortical slices from rat, rabbit, and guinea-pig were incubated in media in which choline, caesium or rubidium replaced sodium.2. Slices of rabbit and guinea-pig renal cortex incubated in oxygenated choline Ringer decreased in volume initially and did not swell over 3 hr at 25 degrees C. There was a steady loss of potassium. Inhibition of metabolism (N(2) + 1 mM (...) iodoacetamide) caused some swelling. Ouabain, 10 mM, in choline Ringer affected neither loss of potassium nor tissue water content.3. Slices of rat renal cortex similarly incubated in choline Ringer swelled over 3 hr at 25 degrees C whether or not metabolism was inhibited; ouabain (15 mM) affected neither tissue potassium loss nor tissue water content.4. Incubation in choline Ringer containing either 0.2 mMp-chloromercuribenzoic acid, or 1 mM ethacrynic acid increased the tissue water content of guinea-pig

163. The effect of the replacement of calcium by strontium on excitation-contraction coupling in frog skeletal muscle Full Text available with Trip Pro

The effect of the replacement of calcium by strontium on excitation-contraction coupling in frog skeletal muscle 1. In frog skeletal muscle strontium can replace calcium in potassium contractures for 5 hr, though it is less effective than Ca. Sr can restore the responsiveness to K after it had been lost in the presence of Mn.2. Muscles refractory to caffeine following repeated exposure to it in the absence of Ca, recover in part following addition of Sr.3. The uptake of (85)Sr was increased

165. Effects of Replacement of External Sodium Chloride with Sucrose on Membrane Currents of the Squid Giant Axon Full Text available with Trip Pro

Effects of Replacement of External Sodium Chloride with Sucrose on Membrane Currents of the Squid Giant Axon It was observed that a reduction of the sodium chloride concentration in the external solution bathing a squid giant axon by replacement with sucrose resulted in marked decreases in the peak inward and steady-state outward currents through the axon membrane following a step decrease in membrane potential. These effects are quantitatively acounted for by the increase in series resistance (...) resulting from the decreased conductivity of the sea water and the assumption that the sodium current obeys a relation of the form I = k(1)C(1) - k(2)C(2) where C(1), C(2) are internal and external ion activities and k(1), k(2) are independent of concentration. It is concluded that the potassium ion current is independent of the sodium concentration. That the inward current is carried by sodium ions has been confirmed. The electrical potential (or barrier height) profile in the membrane which drives

172. Vasorelaxant action of the total alkaloid fraction obtained from Solanum paludosum Moric. (Solanaceae) involves NO/cGMP/PKG pathway and potassium channels. (Abstract)

Vasorelaxant action of the total alkaloid fraction obtained from Solanum paludosum Moric. (Solanaceae) involves NO/cGMP/PKG pathway and potassium channels. Solanum paludosum Moric. (jurubeba-roxa) is commonly used to treat hypertension as a substitute for Solanum paniculatum L. (jurubeba verdadeira). The total ethanolic extract from the root bark of Solanum paludosum have been found to cause hypotension in rats.To investigate the mechanism by which the total alkaloid fraction obtained from (...) -radical nitric oxide), 1-H-[1,2,4]-oxadiazolo-[4,3a]-quinoxalin-1-one (ODQ, selective blocker of soluble guanylate cyclase), Rp-8-bromo-β-phenyl-1,N(2)-ethenoguanosine 3':5'-cyclic monophosphorothioate sodium salt hydrate (Rp-8-Br-PET-cGMPS, competitive inhibitor of cGMP-dependent protein kinase G) or TEA(+) (tetraethylammonium, nonselective potassium channel blocker), the vasorelaxant effect was significantly reduced, suggesting the involvement of NO/sCG/PKG pathway and potassium channel opening

173. THE IMPORTANCE OF POTASSIUM AFTER OPERATION Full Text available with Trip Pro

THE IMPORTANCE OF POTASSIUM AFTER OPERATION A deficiency of potassium in a patient after operation is manifest clinically by anorexia, malaise, apathy, weakness, abdominal distention and hypochloremia. Many patients who have had a prolonged disturbance in nutrition may have a "subclinical" hypopotassemia. Prophylaxis by means of replacement of the potassium excreted daily in the urine is the ideal treatment. When the clinical picture of potassium deficit develops, the amount of the potassium (...) ion needed for replacement should be calculated on the basis of the total amount of water in the body of the patient.

174. CALCIUM INFLUX IN SKELETAL MUSCLE AT REST, DURING ACTIVITY, AND DURING POTASSIUM CONTRACTURE Full Text available with Trip Pro

CALCIUM INFLUX IN SKELETAL MUSCLE AT REST, DURING ACTIVITY, AND DURING POTASSIUM CONTRACTURE Calcium influx in the sartorius muscle of the frog (Rana pipiens) has been estimated from the rate of entry of Ca(45). In the unstimulated preparation it is about equal to what has been reported for squid giant axons, but that per impulse is at least 30 times greater than in nerve fibers. The enhanced twitch when NO(-) (2) replaces Cl(-) in Ringer's is associated with at least a 60 per cent increase (...) in influx during activity, whereas this anion substitution does not affect the passive influx significantly. Calcium entry during potassium contracture is even more markedly augmented than during electrical stimulation, but only at the beginning of the contracture; thus, when a brief Ca(45) exposure precedes excess K(+) application, C(45) uptake is increased three- to fivefold over the controls not subjected to K(+), whereas when C(45) and K(+) are added together, no measurable increase in Ca(45) uptake

RADIOACTIVITY AND PHYSIOLOGICAL ACTION OF POTASSIUM 1. The non-radioactive cesium ion can replace the potassium ion almost quantitatively in solutions required for the development of the egg of the sea urchin into swimming blastulae. 2. Thorium chloride and uranium acetate cannot replace the potassium chloride in the solutions required for the development of the egg. 3. Thorium chloride and uranium acetate do not antagonize the action of the potassium contained in sea water upon the development

CHEMICAL CHARACTER AND PHYSIOLOGICAL ACTION OF THE POTASSIUM ION 1. It is shown that the NH(4) ion acts in cases of antagonism on the egg of Fundulus more like the K ion than the Na ion; this corresponds to the fact that in its general chemical behavior the NH(4) ion resembles the K ion more closely than the Na ion. 2. It is shown that the tolerance of sea urchin eggs towards the Li ion can be increased 500 per cent or more if at the same time a certain amount of Na ion is replaced by K, Rb

177. THE CONCENTRATION EFFECT WITH VALONIA: POTENTIAL DIFFERENCES WITH DILUTED POTASSIUM-RICH SEA WATERS Full Text available with Trip Pro

THE CONCENTRATION EFFECT WITH VALONIA: POTENTIAL DIFFERENCES WITH DILUTED POTASSIUM-RICH SEA WATERS The concentration effect with sea waters containing more than the normal amount of potassium has been studied in Valonia macrophysa. This was done by comparing the initial changes in P.D. across the protoplasm when natural sea water bathing the cell was replaced by various isotonic dilutions of KCl-rich sea waters. With small dilutions of KCl-rich sea waters, the P.D.-time curves are of the same (...) in the concentration of potassium, and increases with increasing dilution. That is, with these higher dilutions, the sign of the concentration effect is reversed, becoming the same as with diluted natural sea water. The greater the concentration of KCl in the undiluted sea water, the higher is the critical dilution at which K(+) ceases to influence the P.D. For a wide range of sea waters containing both KCl and NaCl, it is shown that the concentration effect above the critical dilution is determined solely

178. DELAYED POTASSIUM EFFECT IN NITELLA Full Text available with Trip Pro

DELAYED POTASSIUM EFFECT IN NITELLA In normal cells of Nitella replacement of NaCl by KCl makes the P.D. much less positive: this is called the potassium effect. Cells which have lost the potassium effect usually show little or no change of P.D. when NaCl is replaced by KCl but an occasional cell responds after a delay. It seems possible that the delay may be largely due to the time required for potassium to combine with an organic substance, thus forming a compound which sensitizes (...) the protoplasmic surface to the action of potassium.

179. EFFECTS OF POTASSIUM ON THE POTENTIAL OF HALICYSTIS Full Text available with Trip Pro

EFFECTS OF POTASSIUM ON THE POTENTIAL OF HALICYSTIS Sea water in which sodium has been replaced by potassium produces about the same degree of negativity in Halicystis and in Valonia. With increasing dilution of this sea water up to 1 / 16 the degree of negativity steadily falls off in Halicystis. This differs from the situation in Valonia where Damon finds that with increasing dilution the negativity passes through a minimum after which increasing dilution produces increasing negativity

180. A MODEL OF THE POTASSIUM EFFECT Full Text available with Trip Pro

A MODEL OF THE POTASSIUM EFFECT The protoplasm of certain cells is able to distinguish electrically between K(+) and Na(+). This has been called the potassium effect. This is illustrated by experiments with Nitella. When 0.01 M KCl which has stood in contact with Nitella is replaced by 0.01 M NaCl the P.D. changes in a positive direction by an amount which varies between 30 and 95 mv. This ability to distinguish between K(+) and Na(+) disappears with the removal of an organic substance from (...) the cell. The amount of this substance is doubtless too small to make it possible to obtain enough for analysis. An attempt has therefore been made to find an organic compound which can produce similar effects. It is found that when M/1 KCl in contact with nitrobenzene (previously shaken with M/1 KCl) is replaced by M/1 NaCl the potential changes in a positive direction to the extent of 67 mv. which compares favorably with the values found in Nitella. This is not due to a greater mobility
