Abstract
PURPOSE This study aimed to assess the serum levels of intracellular adhesion molecule (sICAM-1), and vascular cell adhesion molecule (sVCAM-1), in the first psychotic episode schizophrenia (SZ) patients, before and after six months of antipsychotic treatment. PATIENTS AND METHODS The study included 50 patients with a first hospitalization for SZ and 50 healthy control subjects that were patient-matched regarding age, gender, body mass index and smoking status. The evaluation included the presence of cardiovascular risk factors, measurements of systolic and diastolic blood pressure, body mass index, smoking status, ankle-brachial index, carotid intima-media thickness, and echocardiography. The Brief Psychiatric Rating Scale (BPRS) score was calculated for the patients. The plasma levels of fasting glucose, total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides, sICAM-1 and sVCAM-1 were determined at baseline in all subjects and after six months of antipsychotic treatment. Thirty patients (60%) were treated with olanzapine and 20 (40%) with risperidone. RESULTS The average age of patients experiencing their first episode of SZ was 29.7±6.6 years, and 23 (46%) were men. The initial sICAM-1 levels of the patients were lower than those of the control group (P<0.0001), and increased after treatment (P=0.02), but remained lower than in the healthy controls (P=0.026). The initial levels of sVCAM-1 levels were higher in the patients (P<0.0001) and decreased after treatment (P<0.0001) to values that were similar to those of the control group (P=0.39). The only independent predictor of a baseline BPRS over 120 was the baseline sVCAM-1 level (P<0.0001). Antipsychotic treatment induced significant decreases in BPRS score (P<0.0001), in systolic (P=0.005) and diastolic (P<0.0001) blood pressure, in HDL-c (P=0.02), as well as significant increases in blood glucose (P<0.01) and LDL-c (P<0.001), with no differences between olanzapine and risperidone. CONCLUSION In the patients experiencing an FEP of SZ, the levels of sICAM-1 were lower, while the levels of sVCAM-1 were higher than in the healthy control subjects. The antipsychotics used in the treatment of schizophrenia increased sICAM-1 and decreased sVCAM. The baseline level of sVCAM-1 was an independent predictor of a BPRS score >120 at baseline.

Abstract
Structure-toxicity relationships for a series of 75 azo and azo-anilide dyes and five diazonium salts were developed using Hydractinia echinata (H. echinata) as model species. In addition, based on these relationships, predictions for 58 other azo-dyes were made. The experimental results showed that the measured effectiveness Mlog(1/MRC50) does not depend on the number of azo groups or the ones corresponding to metobolites, but it is influenced by the number of anilide groups, as well as by the substituents’ positions within molecules. The conformational analysis pointed out the intramolecular hydrogen bonds, especially the simple tautomerization of quinoidic (STOH) or aminoidic (STNH2) type. The effectiveness is strongly influenced by the “push-pull” electronic effect, specific to two hydroxy or amino groups separated by an azo moiety (double alternate tautomery, (DAT), to the –COOH or –SO3H groups which are located in ortho or para position with respect to the azo group. The levels of the lipophylic/hydrophilic, electronic and steric equilibriums, pointed out by the Mlog(1/MRC50) values, enabled the calculation of their average values Clog(1/MRC50) (“Köln model”), characteristic to one derivative class (class isotoxicity). The azo group reduction and the hydrolysis of the amido/peptidic group are two concurrent enzymatic reactions, which occur with different reaction rates and mechanisms. The products of the partial biodegradation are aromatic amines. No additive or synergic effects are noticed among them.
