Ternary Copper(II) Complexes With Indomethacin, a Potent Non-Steroidal Antiinflammatory Drug. Crystal Structure of Bis (Dimethylformamide)-Tetrakis[1-(4-Chlorobenzoyl)-5-Methoxy-2-Methyl-1-H-Indole-3-Acetato]Dicopper(II). Antiinflammatory Properties and Prevention of Gastrointestinal Side Effects by Nanocapsules
Two ternary copper(ll) complexes of indomethacin [1-(4-chlorobenzoyl)-5-methoxy-2-
methyl-1-H-indole-3-acetic acid] called hereafter lndo, were prepared and characterized by single
crystal X-ray diffraction. The first complex Cu2(Indo)4(DMF)2 I crystallizes in space group P-1 (a =
10.829(2), b = 13.379(2), c = 16.491(3) Å; α = 105.58(2), β = 101.06(2), γ = 106.96(2)°; V= 2104.6(6) Å3, Z= 1). The title molecule is a centrosymmetric binuclear complex, with Cu atoms
bridged by the carboxylate moieties of four indomethacinate ligands. The four nearest O atoms
around each Cu atom form a square planar arrangement with the square pyramidal coordination
completed by the O atom of N,N′-dimethylformamide. Daily administration for seven days of 1 mg/kg
of indomethacin, I and I encapsulated into liposomes induces a weak inflammation of rat gastrointestinal
tract. I was less inflammatory than indomethacin but the better protection was brought by
encapsulation of the compound. This might be of interest in sustained therapies of chronic
inflammatory diseases
In Vivo Nitric Oxide Synthase Inhibitors Can Be Deprived of This Activity: Unexpected Influence of the Tetrachloroplatinate(II) Counteranion. Crystal Structures of Bis(S-Methyl-Isothiouronium)-N,N′-Bis(3-Guanidinopropyl)Piperazinium and Hexamidinium Tetrachloroplatinates(II) Salts
The synthesis and crystal structures of bis(S-methylisothiouronium) (MSTUH)+, N,N′-bis((3-
guanidinopropyl)piperazinium (PipeC3GuaH4)4+ and hexamidinium (HexaH2)2+ tetrachloro platinate(ll) salts ( called hereafter PtMSTU, PtPipeC3Gua and PtHexa respectively ) were
investigated. These compounds contain the “amidine” function ( - C(=NH)NH2 ) in which the H
atoms supplied by the acid have become attached to the imino group of each terminal amidino
function. Moreover, in PtPipeC3Gua, the nitrogen atoms of the chair-piperazine moiety are also
protonated. The influence of tetrachloroplatinate(ll) counteranion ( versus sulfate, nitrate and
diisethionate ) in the in vivo nitrite inhibition by the (MSTUH)+, (PipeC3GuaH4)4+ and (HexaH2)2+ cations was investigated. The three tetrachloroplatinate(ll) salts, unexpectedly, do not inhibit
significantly the in vivo nitrite production in comparison with the other salts (sulfate, nitrate and
diisethionate and their corresponding previous countercations) which exhibit NO synthase
inhibition, especially bis(S-methylisothiouronium) sulfate, a selective and potent inducible NO
synthase (iNOS) inhibitor commonly used as standard
What makes people decide who to turn to when faced with a mental health problem? Results from a French survey
<p>Abstract</p> <p>Background</p> <p>The unequal use of mental health care is a great issue, even in countries with universal health coverage. Better knowledge of the factors that have an impact on the pathway to mental health care may be a great help for designing education campaigns and for best organizing health care delivery. The objective of this study is to explore the determinants of help-seeking intentions for mental health problems and which factors influence treatment opinions and the reliance on and compliance with health professionals' advice.</p> <p>Methods</p> <p>441 adults aged 18 to 70 were randomly selected from the general population of two suburban districts near Paris and agreed to participate in the study (response rate = 60.4%). The 412 respondents with no mental health problems based on the CIDI-SF and the CAGE, who had not consulted for a mental health problem in the previous year, were asked in detail about their intentions to seek help in case of a psychological disorder and about their opinion of mental health treatments. The links between the respondents' characteristics and intentions and opinions were explored.</p> <p>Results</p> <p>More than half of the sample (57.8%) would see their general practitioner (GP) first and 46.6% would continue with their GP for follow-up. Mental health professionals were mentioned far less than GPs. People who would choose their GP first were older and less educated, whereas those who would favor mental health specialists had lower social support. For psychotherapy, respondents were split equally between seeing a GP, a psychiatrist or a psychologist. People were reluctant to take psychotropic drugs, but looked favorably on psychotherapy.</p> <p>Conclusion</p> <p>GPs are often the point of entry into the mental health care system and need to be supported. Public information campaigns about mental health care options and treatments are needed to educate the public, eliminate the stigma of mental illness and eliminate prejudices.</p
En Médecine : du témoignage du corps à l’hypochondrie sociale
Il y a trente ans déjà , dans un article qui eut un certain retentissement, le sociologue N.H. Jewson montrait comment le progrès des connaissances médicales au XIXe siècle s’accompagnait d’une exclusion progressive de « l’homme-malade ». Non sans une certaine idéalisation nostalgique, Jewson identifiait au XVIIIe siècle une bedside medicine dans laquelle l’examen physique n’aurait pas encore supplanté la prise en compte des sensations et sentiments du patient ; où le diagnostic reposait sur u..
