Fifty patients, twenty-five suffering from severe knee osteoarthritis and twenty-five from acute hip osteoarthritis, received pentazocine or a new preparation of tilidine-naloxone for a period of 2 weeks, in a double-blind study. The two drugs were found to have the same efficacy and tolerance in both diseases with a minor but not statistically significant superiority for tilidine-naloxone. Similar quantities of drugs were taken over the study period, while patients were allowed to take as many as 8 capsules per day to relieve pain. There were quite equivalent side-effects and no marked changes in laboratory tests. [less ▲]

While neuroleptic therapy with classical compounds has frequently been associated with extrapyramidal side effects, clozapine has revealed an interesting antipsychotic profile without producing any clearcut motor side effects. However, some adverse reactions remained that stimulated the search for improved antipsychotic agents. The aim of this study was to characterize the behavioural and neurochemical profiles of typical neuroleptics (chlorpromazine, haloperidol), clozapine, and four newly synthesized clozapine-analogues. Affinity for dopaminergic (D1,D2), serotonergic (5-HT(2)) and cholinergic (muscarinic) receptors were measured and the ratios of these different binding affinities were determined and correlated with the behavioural effects of the drugs in a complex temporal regulation task in the dog. The four clozapine-analogues showed most of the behavioural characteristics previously described for neuroleptics and their neurochemical profile, particularly their 5-HT(2)/D2 pKi ratio, was compatible with an atypical antipsychotic effect. Among these drugs, JL5 and JL13 showed a high degree of similarity with clozapine. Like clozapine, they did not induce catalepsy and stereotypy/hyperkinesia. Moreover, other motor effects were also reduced (ataxia, akinesia, dystony). and tremor and sialorrhea were completely absent with these two molecules. [less ▲]

Chemical composition of the essential oils of Cistus libanotis from eastern Morocco (Tafoughalt and Jerrada) extracted from different season was analyzed by GC-MS and GC-FID. The hydro-distilled essential oil content ranged from 0, 27 % to 0, 46%, the maximum amounts were observed in summer while minimum in winter for Tafoughalt, whereas the oil obtained from Jerrada had the highest yield (0, 61 %). The essential oils consisted of terpineol-4 as the most abundant component (18, 70 % - 24, 91 %), followed by γ-terpinene (9, 82 % - 12, 25 %), camphene (5, 86 % - 13, 58 %), sabinene (7, 86 % - 9, 89 %) and α-thujene (6, 92 % - 10, 12 %). Samples collected in all seasons were found to be richer in monoterpenes hydrocarbons (52, 68 % - 57, 59 %). None sesquiterpene hydrocarbons found in the oils from summer and autumn. Drying period of leaves at normal air laboratory and distillation time also affect the oil content and composition. There was variation in terpineol-4 content from 22, 23 % (4th day of drying) to 19, 27 % (29th day of drying), and from 35, 60 % (1 hour of distillation) to 24, 17 % (4 hours of distillation). It can be concluded that the harvesting season, period of drying and the time of distillation had an effect on the yield of essential oil and chemical composition of various compounds. [less ▲]

In order to critically evaluate the potential of dual cyclodextrin (CD) systems in CE, enantioseparation of the neutral chiral analyte glutethimide (GT) was performed using: a) charged CDs; b) combinations of charged and neutral CDs (dual CD systems), and c) CD-modified micellar electrokinetic chromatography (CD-MECK). The results of this comparative study indicate that properly designed dual CD systems may in certain cases represent a valuable alternative to CD-MEKC and electrokinetic chromatography involving charged CDs for enantioseparation of neutral analytes.

The ginsenoside content of different ginseng species (Panax ginseng, P. quinquefolium, and P. vietnamensis) from different sources (roots from field-grown plants or from in vitro cultures, cells from solid calluses or from liquid cultures, commercial powders, and suspensions) is evaluated by means of a new high-performance thin-layer chromatography (HPTLC) technique combining an automatic TLC sampler and scanner. The results are compared with those obtained through more classical gross spectrometric and high-performance liquid chromatography (HPLC) techniques. HPTLC and HPLC allow the separation and estimation of the different ginsenosides. For this, HPTLC is faster and simpler than HPLC. Both techniques determine less amounts of ginsenosides than spectrophotometry, which displays overestimated values caused by light absorption by contaminating osides. In vitro cultured cells and roots contain the same ginsenosides as those produced by their mother plants, although at quite lower levels. The culture media also accumulates ginsenosides. [less ▲]

The phytophagous two-spotted spider mite Tetranychus urticae Koch is a ubiquitous species, present worlwide on a large variety of plant families. Since T. urticae resistance spread rapidly, biological control tactics are crucial to manage spider mite populations. In this respect, plant-derived essential oil products are a good alternative as they are, in general, considered as minimum-risk pesticides. In that context, laboratory experiments were conducted to assess the toxicity of essential oil of Deverra scoparia endemic plant to North Africa on females of the two spotted spider mite T. urticae (Koch). Essential oil was distillated from fresh leaves from D. scoparia and was sprayed on groups of adults females. The susceptibility of these females to D. scoparia essential oil was tested. A series of dilutions were used to bracket the dose-response range. Tests proved that female mortality increased with essential oil concentration with DL50 and DL90 values of 1.79 mg/l and 3.16 mg/l, respectively. The analysis of D. scoparia essential oil using GC-MS revealed presence of 10 major constituents: alpha-thujene, alpha-pinene, sabinene, myrcene, 3-carene, ocimene, terpinene-4-ol, pulegone, eugenol and beta-eudesmol. For a comprehensive evaluation of the potential of D. scoparia essential oil as acaricidal, individual blends activity of these constituents were tested against T. urticae female. Toxicity of blends of different components indicated significant differences among the active and inactive components, with the presence of all constituents necessary to have toxicity near to that of whole D. scoparia oil. The results showed that natural oil of D. scoparia and some of its constituents have potential for development as botanical acaricide, at least against T. urticae. [less ▲]

Damselfishes show significant biodiversity in the coral reefs. To better understand such diversity, an ecomorphological approach was investigated in the trophic morphology of eight species of Pomacentridae (Chromis acares, C. margaritifer, Dascyllus aruanus, D. flavicaudus, Pomacentrus pavo, Plectroglyphidodon johnstonianus, Pl. lacrymatus and Stegastes nigricans) belonging to different trophic guilds (zooplankton, algal, coral polyp feeders and omnivores). Geometric morphometrics were used to quantify size and shape variations in four skeletal units: (1) neurocranium, (2) suspensorium and opercle, (3) mandible and (4) premaxilla. This method allowed us to reveal shape and size differences correlated to functional diversity both within and between trophic guilds. Among zooplanktivores, C. margaritifer, D. aruanus and D. flavicaudus have a high and long supraoccipital crest, short mandibles forming a small mouth and high suspensoria and opercles. These three species can be considered to be suction feeders. In the same guild, C. acares shows opposite characteristics (long and thin mandibles, lengthened neurocranium and suspensorium) and can be considered as a ram feeder. Among herbivores and corallivores, the two species of Plectroglyphidodon and S. nigricans can be considered as grazers. Differences in skeletal shape are mainly related to improving the robustness of some skeletal parts (broad hyomandibular, short and high mandibles). The shapes of P. pavo, which feeds largely on algae, strongly differ from that of the other three grazers exhibiting similar morphological characteristics to C. acares (e.g., long and shallow suspensorium, lengthened neurocranium). This highlights likely differences concerning cutting or scraping method. Finally, no strong correlations exist between size and shapes in the eight studied species. Size difference among species having a very similar shape could be viewed as a factor optimizing resource partitioning. [less ▲]

Modifications of cell shape induced in cultured newborn rat astroblasts by serum deprivation or dibutyryladenosine 3'-5' monophosphate (dBcAMP) are described. Serum suppression modifies the adhesitivity of the cells to the substrate, but this modification is not consistent with a true differentiation. The main ultrastructural feature of dBcAMP-treated astroblasts is the presence of an extensive system of 90 A microfilaments, while control cells are relatively devoid of these structures. [less ▲]

The clinical safety and efficacy of sirolimus plus reduced-dose tacrolimus was evaluated in de novo renal allograft recipients enrolled in a comparative, open-label study. Methods. One hundred twenty-eight renal allograft recipients were randomly assigned (1:1) to receive reduced-dose tacrolimus plus sirolimus (rTAC) or standard-dose tacrolimus and sirolimus (sTAC) for 6 months. The primary efficacy endpoint was calculated creatinine clearance values at 6 months. Results. Demographic variables were similar between groups. At 6 months, mean ( standard deviation) calculated creatinine clearance was significantly improved in the rTAC group (63.8 vs 52.7 mL/min, P ¼ .005), although mean serum creatinine values were not significantly different. Patient survival (95.2% and 96.9%) and graft survival (93.7% and 98.5%) were similar between the rTAC and sTAC groups, respectively. Acute rejection rates were 17.5% with rTAC and 7.7% with sTAC (P ¼ .095). Conclusions. The rTAC regimen provided effective immunosuppression and was associated with improved creatinine clearance. Adequate immunosuppressant exposure must be achieved in the early postoperative period to minimize the risk of acute rejection. [less ▲]
