Abstract
Chlorpromazine (CPZ) equivalents are often used as a relative measure of the antipsychotic potency of neuroleptics. We review the CPZ equivalents of 33 neuroleptics and illustrate why imprecisions or discrepancies will be difficult to eliminate from these values. We nevertheless underline that CPZ equivalents can be clinically useful, since they facilitate the choice of doses of different neuroleptics that should induce comparable antipsychotic effects.

Abstract
Within the sphere of the infectious pathology one usually finds among drug addicts using intravenous methods, a prominent place is occupied by Endocarditis, a serious complication which is one of the more common causes of death among drug addicts. On the basis of the recent literature and their personal experience, the Authors report on several aspects of this illness in addicts, describing the etiological profile and the clinical manifestations in particular, which show clear dissimilarities when compared with infectious endocarditis in patients who are not addicts.

Abstract
The incidence of mitral valve injury resulting from blunt trauma is low. This report presents the case of a 36-year-old male who survived the rupture of both his mitral and tricuspid valves after striking the steering wheel during a motor vehicle accident. Echocardiograms were used to make the diagnosis.

Abstract
Three multiheme c-type cytochromes--the tetraheme cytochrome c3 (molecular weight [MW] 13,500), a dodecaheme cytochrome c (MW 40,800), and a "split-Soret" cytochrome c (MW 51,540), which is a dimer with 2 hemes per subunit (MW 26,300)--were isolated from the soluble fraction of Desulfovibrio desulfuricans (ATCC 27774) grown under nitrate- or sulfate-respiring conditions. Two of them, the dodecaheme and the split-Soret cytochromes, showed no similarities to any of the c-type cytochromes isolated from other sulfate-reducing bacteria, while the tetraheme cytochrome c3 appeared to be analogous to the cytochrome c3 found in other sulfate-reducing bacteria. For all three multiheme c-type cytochromes isolated, the homologous proteins from nitrate- and sulfate-grown cells were indistinguishable in amino acid composition, physical properties, and spectroscopic characteristics. It therefore appears that the same c-type cytochrome components are present when D. desulfuricans ATCC 27774 cells are grown under either condition. This is in contrast to the considerable difference found in Pseudomonas perfectomarina (Liu et al., J. Bacteriol. 154:278-286, 1983), a marine denitrifier, when the cells are grown on nitrate or oxygen as the terminal electron acceptor. In addition, two spectroscopy methods capable of revealing minute structural variations in proteins provided identical information about the tetraheme cytochrome c3 from nitrate-grown and sulfate-grown cells.

Abstract
When purified, a high-potential c-type monohaem cytochrome from the nitrate-respiring organism, Wollinella succinogenes (VPI 10659), displayed a minimum molecular mass of 8.2 kDa and 0.9 mol iron and 0.95 mol haem groups/mol protein. Visible light spectroscopy suggested the presence of an equilibrium between two ligand arrangements around the haem, i.e. an absorption band at 695 nm characteristic of haem-methionine coordination (low-spin form) coexisting with a high-spin form revealed by a band at 619 nm and a shoulder at 498 nm. The mid-point redox potential measured by visible redox titration of the low-spin form was approximately +100 mV. Binding cyanide (Ka = 5 x 10(5) M-1) resulted in the displacement of the methionyl axial residue, and full conversion to a low-spin, cyanide-bound form. Structural features were studied by 300-MHz 1H-NMR spectroscopy. In the oxidized state, the pH dependence of the haem methyl resonances (pH range 5-10) and the magnetic susceptibility measurements (using an NMR method) were consistent with the visible light spectroscopic data for the presence of a high-spin/low-spin equilibrium with a transition pKa of 7.3. The spin equilibrium was fast on the NMR time scale. The haem methyl resonances presented large downfield chemical shifts. An unusually broad methyl resonance at around 35 ppm (pH = 7.5, 25 degrees C) was extremely temperature-dependent [delta(323 K) - delta(273 K) = 7.2 ppm] and was assigned to the S-CH3 group of the axial methionine. In the ferrous state only a low-spin form is present. The haem meso protons, the methyl group and the methylene protons from the axial methionine were identified in the reduced form. The resonances from the aromatic residues (three tyrosines and one phenylalanine) were also assigned. Detailed monitoring of the NMR-redox pattern of the monohaem cytochrome from the fully reduced up to the fully oxidized state revealed that the rate of the intermolecular electronic exchange process was approximately 6 x 10(6) M-1 s-1 at 303 K and pH = 6.31. A dihaem cytochrome also present in the crude cell extract and purified to a homogeneous state, exhibited a molecular mass of 11 kDa and contained 2.43 mol iron and 1.89 mol haem c moieties/mol cytochrome. The absorption spectrum in the visible region exhibited no band at 695 nm, suggesting that methione is not a ligand for either of the two haems. Recovery of only small amounts of this protein prevented more detailed structural analyzes.

Abstract
The effect of two different loading doses of L-tryptophan (0.5 and 1.0 g/Kg b.w.) on excretion of tryptophan metabolites and the relation to the enzyme activities were studied in rats, mice and guinea pigs. In rats there is no ratio between the dosage used and the levels of the metabolites excreted. Doubling the amount of tryptophan administered, a 5-fold increase in the elimination of the metabolites along the kynurenine pathway is obtained. The 1.0 g/Kg load provides a more complete pattern of the metabolites than with the 0.5 g/Kg b.w. load. Kynurenic acid, kynurenine and xanthurenic acid are the chief metabolites excreted. In mice, the urinary excretion of the metabolites is very low with both loads. In guinea pigs, xanthurenic acid is excreted in the highest amount and kynurenic acid and kynurenine also constitute the large fractions with both loadings. The load of 0.5 g/Kg b.w. is preferable to that of 1.0 g/Kg b.w. for not causing B6-deficiency. Liver tryptophan pyrrolase exists in two forms in rats, while in mice and in guinea pigs it is present only as holoenzyme. This enzyme is more active in rats than in the other two species of animals. Kynureninase activity is lower in guinea pigs, but it apparently correlated to the low levels of excretion of the metabolites following this step. Kynurenine aminotransferase is very active in rats and in mice, while it is apparently depressed in guinea pigs, in contrast with the high excretion of xanthurenic and kynurenic acids, that puts in evidence a B6-deficiency. The excretion of tryptophan metabolites and enzyme activities are better correlated in rats.

Abstract
Single low doses (0.25 mg) of dexamethasone were given at 11 p.m., 2, 5 and 8 a.m. on separate days to five normal subjects. The concentrations of cortisol in plasma on the next day were significantly decreased compared to results after placebo administration, and cortisol suppression was maximal after dexamethasone had been given at 8 a.m. Our findings suggests that the postulated phase-advance of circadian rhythms is not a major cause of cortisol non-suppression in depressives given dexamethasone.

Abstract
The presence of the alpha alpha alpha anti-4.2 haplotype and heterozygous beta null thalassemia in a Sicilian family is described. These findings confirm the presence in Italy of a leftward deletion (-alpha 4.2) and indicate that this may not be rare. Furthermore, although the beta thalassemia determinant in this family has a severe expression, the interaction with the triplicated alpha gene does not necessarily express itself as thalassemia intermedia.
