Abstract
A direct fluorescent antibody test was developed for the identification of large spirochetes which are considered to be the cause of swine dysentery. Sera from swine which had recovered from swine dysentery and had been hyperimmunized by the intravenous and intraperitoneal injection of filtered spirochetes were used for conjugation with fluorescein isothiocyanate. A bright greenish fluorescence of large spirochetes was observed with the conjugated serum from hyperimmunized pig No. 1 when diluted 1:8 and hyperimmunized pig No. 2 when diluted 1:2. Pig No. 1 had developed a serum titer of 1:64 using the indirect fluorescent antibody test for large spirochetes. The conjugated serum from the three swine which had recovered from swine dysentery fluoresced spirochetes only when undiluted. The conjugated serum from the two swine treated while having a hemorrhagic diarrhea did not fluoresce spirochetes. No immunofluorescence of Vibrio spp. was observed.

Abstract
Serums from 119 swine exposed to swine dysentery inoculum, and medicated with various drugs, were tested for antibodies to the large spirochete, using the indirect fluorescent antibody test, and were compared in tests with known positive serums from 18 nonmedicated swine which had recovered naturally. An inverse relationship existed between the efficacy of the drug and the serum antibody titer (highest dilution of the serum producing immunofluorescence of large spirochetes). The more efficacious drugs or doses resulted in lesser development of serum antibody. Diarrhea usually seemed necessary for the development of serum antibody. With the less efficacious drugs, there were more days of diarrhea. Some swine had diarrhea but did not develop an antibody titer, and a few swine had a titer but did not develop diarrhea. Swine which developed a titer were more immune against reexposure with infective inoculum. The medicaments, especially those given at higher concentrations, seemed to resolve the diarrhea or prevent the development of diarrhea, occurrences which were necessary for the development of immunity.

Abstract
Using an indirect fluorescent antibody test, immunofluorescence of large spirochetes was observed with serum from swine that had recovered from swine dysentery. The spirochetes were obtained from scrapings of the colonic mucosa on the first day of diarrhea which was the time when the spirochete population was observed to be the highest. Of 29 exposed nonmedicated swine which developed and recovered from a diarrhea characteristic of swine dysentery 27 had antispirochete serum titers which ranged from 1:2 to 1:16. None of the 50 nonexposes swine developed a titer. Of 19 swine with a serum titer and reexposed with infective swine dysentery inoculum, 18 did not develop a diarrhea and were presumed to be immune. Considering these findings it is possible that this test could be used to detect antispirochete antibody in unknown swine serum.

Abstract
In order to obtain information about the conformational features in a polyribonucleotide at the nearest neighbor level, detailed nuclear magnetic resonance studies of the dinucleoside monophosphates ApA, ApG, GpA, UpU, CpC, UpC, and CpU were undertaken. Proton spectra were recorded at 100, 220, 270, or 300 MHz for D2O solutions, 0.01-0.03 M, pD 7.4 at 20+/-2 degrees C. Spectra of ApA, ApG, UpU, and UpC were also recorded in the temperature range of 70-90 degrees C. Unambiguous signal assignments of all proton resonances were made with the aid of selectively deuterated dimers. Complete, accurate sets of nuclear magnetic resonance (NMR) parameters were derived for each nucleotidyl unit by simulation-iteration methods. A complete set of chemical shift and coupling constant data was also obtained for all the constituent monomeric units at a concentration and ionization state comparable to that of the dimers. Conformational properties were evaluated quantitatively for most of the bonds in the dinucleoside monophosphates using procedures developed in earlier studies. All of the dimers have a flexible conformational framework in aqueous solution. While flexibility is allowed and alternate conformations are accessible, these molecules nevertheless attempt to achieve conformational identity by showing preferences--sometimes overwhelming preferences--for certain orientations. Thus the ribose rings exist as equilibrium mixtures of C2'-endo in equilibrium C3'-endo conformers with a bias for the C3'-endo pucker in most cases. The C4'-C5' bonds of both nucleotidyl units show significant preference (70-85%) for a gg conformation. Similarly, the dominant conformer (80-90%) about C5'-O5' is g'g'. Even though an unambiguous determination of the orientation about C3'-O3' cannot be made, there is suggestive evidence that the orientation of the 3' phosphate group is coupled to the ribose conformational equilibrium and it is likely that a 3Eg- in equilibrium 2Eg+ equilibrium exists with a bias for the 3Eg- coupled conformation in which the H3'-C3'-O3'-P dihedral angle is about 34-38 degrees. The individual nucleotidyl units in the dimers differ in several key ways from corresponding monomer conformations. Specifically, the ribose equilibrium C2'-endo in equilibrium C3'-endo shifts in favor of C3'-endo upon dimerization, the only exception being UpU. The C4'-C5' and C5'-O5' bonding network in the dimer forms a stable conformational unit and no correlation exists in the dimers between the conformational preference of this fragment and ribose conformer population. The temperature data for the dimers and dimerization data clearly indicate that the transition C2'-endo leads to C3'-endo is directly related to XCN changes brought about by dimerization and stacking...

Abstract
In patients, pentazocine administered i.v. can have an unusual action for a strong analgesic-an elevation of blood pressure. The objective of this study in rats was to better quantify and explain the molecular mechanism for the vascular action of l-pentazocine and compare it with other analgesics and narcotic antagonists. In anesthetized rats, l-pentazocine (0.3-3 mg/kg i.v.) elevated blood pressure and this effect was potentiated in pithed rats. The contraction appeared to be nonadrenergic as it was not blocked by the alpha blocker, phenoxybenzamine. In vitro, morphine (ED50 = 4 X 10(-5) M) and the l-isomers of pentazocine (ED50 = 8 X 10(-6) M) contracted the spirally cut aortic strip. The l-isomers were approximately 5 times more potent than their d-enantiomers. Contraction of the aorta by l-pentazocine was not inhibited by dibenamine, atropine, diphenhydramine, pyrilamine or indomethacin nor potentiated by propranolol. On the other hand, not only was the contraction highly dependent on the concentration of calcium in the bath but it was also blocked by verapamil and SKF-525A, drugs known to inhibit transmembrane calcium influx. Naloxone (3 X 10(-4) to 1 X 10(-3) M), which produced no contractile effect by itself, reduced aortic contraction of l-pentazocine to the greatest extent, that of potassium moderately and that of norepinephrine only slightly. The naloxone blockade of l-pentazocine vascular contraction was reversed by increasing Ca++ concentration in the media, suggesting the action of naloxone may resemble a calcium blocker. It is proposed that a direct, stereoselective and calcium dependent vascular action of l-pentazocine contributes to its ability to raise blood pressure. The possibility that in high doses narcotic antagonists may decrease calcium influx should also be considered.

Abstract
Activity of L-cysteinesulfinate carboxy-lyase (CSC) and persulfurase was measured in livers of rats fed 15% casein diets supplemented with (1) 0.53% cysteine, (2) 0.40% cysteine, (3) 0.40% cysteine + 0.10% sulfate, (4) 0.42% sulfate, or (5) 0.42% sulfate + 0.40% cysteine. The diets were fed to adult rats for 1 week and to weanling rats for periods of 1 and 4 weeks. At the end of each feeding period, the highest CSC activity was detected in livers from animals fed diet 4, but no differences in CSC activity were detected among livers from the other four groups. Persulfurase activity did not differ significantly among those weanling or adult rats fed the diets for 1 week but was lower among those fed diet 4 than diet 5 for 4 weeks. The acitivity patterns did not parallel those of taurine excretion or conjugation observed previously among rats fed the same diets, and may indicate that factors other than taurine synthesis and ingestion control those processes.

Abstract
The solution conformations of UDPG, UDPGN, UDPGal, UDPM, UDPGluc, UDPGalc, ADPG, ADPM, GDPG, GDPM, and CDPG and their components Glu-1-P, Gal-1-P, Man-1-P, Gluc-1-P, Galc-1-P, ADP, GDP, UDP, and CDP are studied by high resolution fast Fourier transform nuclear magnetic resonance spectroscopy with iterative computer line shape simulation. The following results were observed. (1) The six-membered ring is in 4C1 chair form with the C(5')-C(6') bond in gg equilibrium tg equilibrium for the derivatives of glucose and mannose and gt equilibrium tg for those of galactose. (2) No conformational preference can be detected for C(1')-O(1') bond in hexose-1'-P moiety. (3) Chemical shift dependencies for the pyranoid ring protons and their structural and conformational relations are: (a) axial proton is at higher field than equatorial: (b) the shielding effect of a gauche vicinal hydroxyl group is stronger than a trans vicinal; (c) the vicinity of a hydroxyl group located more than three bonds away tends to shift the proton downfield. (4) The conformation of the nucleoside 5'-diphosphate part is [anti, 2E equilibrium 3E, g'g' equilibrium g't', g'g' equilibrium g''/t''], with slight variation of each conformation occuring for individual compounds. (5) No significant interactions are detected between the hexose and nucleoside parts in the nucleoside diphosphohexoses, and the hexose and nucleoside components display the same conformational preference as they become integrated to form nucleoside diphosphohexoses.

Abstract
Hydrogen-1 and phosphorus-31 nuclear magnetic resonance spectra of 5'-AMP, 5'-GMP, 8-aza-5'-GMP, adenosine, 8-aza-adenosine, and guanosine were obtained at biological pH values at a concentration sufficiently low to obtain information regarding their intramolecular solution conformation. The spectra were analyzed by computer simulation. It is shown that all of the above nucleosides and nucleotides have a flexible molecular framework in aqueous solution, 5'-AMP and 5'-GMP showing preference for anti(2-E in equilibrium 3-E)gg-g'g' conformations and the 8-aza analogs showing preference for (syn in equilibrium anti)-(2E in equilibrium 3-E) - g/t-g'g' conformations. In addition, aza substitution causes increase in 3-E sugar populations and in the populations of g'/t' conformers. It is argued that in the 8-aza analogs repulsive electrostatic interactions would prevail between --N (see article) at the 8 position and the negatively charged phosphate group, if the molecule existed in the anti-gg orientation. Such electrostatic repulsions can be relieved by rotating the C(4')--C(5') bond from gg to g/t orientations as well as by torsional variation about the glycosidic linkage from anti to syn conformation. Rotation from anti to syn orientation, for steric and electrostatic reasons, necessitates a simultaneous rotation about the C(4')--C(5') bond from gg to g/t conformation. The observation that the 8-aza substitution in 5'-beta-purine nucleotides cause a depopulation of gg and anti conformers with corresponding increase in the population of g/t and syn orientation seems to support the above thesis. The finding that rotational variation about a bond such as C(4')--C(5') is accompanied by torsional variation about C(5')--O(5') and the glycosidic bonds, as well as changes in the endocyclic torsion angles of the ribose moiety, gives important insight into the engineering of nucleic acid components: even though they in general prefer certain conformations, there is enough flexibility present in their molecular framework, that the entire system can undergo conformational adjustment in response to a perturbation. A conformational basis for the antileukemic effects of 8-aza purines is proposed.

Abstract
In the isolated guinea pig heart, histamine H1-receptor antagonists inhibit the histamine-induced negative dromotropic effect, but not the positive inotropic and chronotropic effects (Levi and Kuye, 1974, European J. Pharmacol. 27, 330). Burimamide, the H2-receptor antagonist, inhibits the positive chronotropic effect of histamine (Black et al., 1972, Nature 236, 385). In this study, the hypothesis that H1- and H2-receptors selectively mediate the various cardiac effects of histamine was tested: (a) by investigating the inhibition of cardiac histamine effects by burimamide; (b) by studying the cardiac effects of 2-methylhistamine (an H1-agonist) and 4-methylhistamine (an H2-agonist). Burimamide, as a function of concentration, inhibited the positive inotropic and chronotropic effects of histamine, whereas it attenuated the negative dromotropic effect of histamine at the higher concentration only. 4-Methylhistamine caused dose-dependent positive inotropic and chronotropic but not negative dromotropic effects; conversely, with 2-methylhistamine the negative dromotropic effect prevailed. Sinus tachycardia and slowing of atrioventricular conduction were also obtained in the guinea pig in vivo by the i.v. administration of histamine. Burimamide selectively antagonized the positive chronotropic effect, whereas promethazine (an H1-antagonist) selectively inhibited the negative dromotropic effect. These results substantiate the hypothesis that H2-receptors mediate the histamine-induced increase in rate and contractility, whereas H1-receptors mediate the slowing of atrioventricular conduction.

Abstract
Exposure of the tongue to artichoke can make water taste sweet. Two major active components of artichoke are the salts of chlorogenic acid and cynarin. The sweetening of substances by temporarily modifying the tongue, rather than by adding a substance sweet in itself, may provide an alternative to currently used nonnutritive sweeteners.
