The ligand was prepared by fusing sulfamethoxazole and dimedone at (170) ?C for half hour. The prepared ligand was characterized by FTIR,UV - Vis spectroscopy, H1,C3 - NMR spectra, mass spectra, molar conductivity measurement and melting point. The molecular structure for the ligand [H2L] which was proposed as drawn in the figure below : - Ligand [H2L]The complexes prepared using reflux in ethanol as solvent were two types namely : - 1 - Complexes of (1 : 1) mole ratio formula [M(H2L)(H2O)2]Cl22 - Complexes of (1 : 1 : 1) mole ratio formula [M(H2L)(HA)] in the presence of KOH as a base, Where : - M(II) = (Co ,Ni ,Cu) HA= 3 - amino phenol. Spectroscopic methods (FT - IR, UV - Vis spectroscopy) along with (A.A), chloride content and melting point were carried out in addition to molar conductance were done for the characterization of all complexes.The proposed tetrahedral geometry around the metal ions studied were concluded from these measurements. [M(H2L)(H2O)2]Cl2 [M(H2L)(HA)]Molar ratio method were used to determine M to L ratio at maximum wave length (?max=455nm ).The ratio were (1 : 1) mole for both complexes (1) and (4). Bentonite clay was used as adsorbent surface to gather with complexes (1) and (4). The adsorption time investigated was between (15 - 120) min at (25)°C as constant concentration for complexes being (70) mg/L for complex (1) and (50) mg/L for Complex (4) and mesh 75))?m. The results revered that the time needed to reach concentration equilibrium in the were 60 to 75 min for complex (1) and (4). during studying isotherm adsorption for the two complexes on bentonite surface, the results revealed that the trend of the adsorption isotherm was (L1) type according to Giles classification , which means that the adsorbent distributed horizontally on the bentonite surface to from a single adsorption layer type langmire.The adsorption phenomenon was studied at different temperatures (10, 25, 37.5, and 50) oC. The results of the adsorption for both complexes on bentonite surface were showed an increase with increasing temperature (endothermic process). Thermodynamic functions (?Ho, ?Go, and ?So) were calculated and the results were discussed. Generally, the increase in the pH of solution was showed an increase in quantity of both complexes that adsorbed on bentonite clay surface at a certain temperature. The study proved that an increase of adsorbent weight may be enhanced the adsorption process of both complexes. Moreover, the particle size of clay surfaces has an influence on the adsorption process showing an increase in adsorption quantity as the particle size decreased.

Abstract: ترتبط بعض الامراض النفسية مثل مرض الاكتئاب الشديد والفصام بتغيرات مناعية حتى ولو كان الشخص سليم من الناحية الجسمية. على الرغم من ان هذين المرضين لايعتبران حاليا من الامراض المناعية الاساسية لكن توجد ادلة تقترح كون الالتهاب يلعب دورا في عملية الاصابة بالاك | Psychiatric illnesses, particularly major depressive disorder (MDD) and schizophrenia, are associated with inflammatory processes even in individuals who are otherwise physically healthy. While it is unlikely that MDD and schizophrenia are a primary inflammatory disorder, evidence suggesting that inflammation plays a subtle role in the pathophysiology of MDD and schizophrenia has been obtained. Several studies have shown that proinflammatory markers have increased in these disorders. However, these studies have included patients with obvious inflammation, i.e., patients with C - reactive protein >6 mg/L. A comprehensive study concluding that these conditions are inflammatory disorders and inflammation is due only to these two disorders have not been performed. In the present study, the inflammatory natures of MDD and schizophrenia were investigated. To achieve this goal, serum levels of the interleukins - 6 (IL - 6) and interleukins - 18 (IL - 18), tumor necrosis factor alpha (TNF?), and soluble interleukin - 2 receptor (sIL - 2R) in MDD and schizophrenia were obtained and compared with those of the control group. The total serum and ionized levels of calcium (Ca) and magnesium (Mg) in the studied groups were then measured.Significant increases (p < 0.05) in the serum levels of IL - 6, IL - 18, TNF?, and sIL - 2R in the MDD and schizophrenic groups were observed in comparison with those of the control group. In general, the schizophrenic group showed higher levels of inflammatory markers than the MDD and control groups. These results indicate a clear inflammatory state in both disorders. The schizophrenic patients exhibited significant changes in the ratios of T. Ca/Mg and I. Ca/Mg in comparison with those of the healthy and MDD patients; this finding reveals that T. Ca/Mg and I. Ca/Mg ratios are better indicators of cation state than serum cation levels alone.Basing on the results of the present study, we concluded that the immunological responses of the MDD and schizophrenia are significantly stimulated. These conditions may be considered inflammatory disorders because of increased pro - and inflammatory factors in both disorders.Anti - inflammatory drugs may be potentially used as an adjuvant aid in treating schizophrenia and MDD. Future studies may involve investigating other proinflammatory markers and following up results of treated patients that utilized and did not utilize anti - inflammatory drugs.

Abstract: تم تصميم الدراسة الحالية للتخلص من عقاري الباراسيتامول والبروكائين باستخدام الاشعة الفوق بنفسجية وبوجود اوكسيد الزنك كعامل مساعد، حيث سلطت الدراسه الضوء على اهمية كل من الضوء والعامل المساعد كعوامل اساسيه في التفكك الضوئي المحفز لكلا الدوائين.تضمنت الدرا | The current study is designed to treat the paracetamol and procaine by using UV light and ZnO as catalyst. This study explains the importance of the UV light and catalyst as a basic factors in the photocatalytic degradation for both paracetamol and procaine drugs. The study includes the measure of the rate of photocatalytic oxidation by measuring the absorbance of samples of aqueous solution for both drugs which is treated by UV light and ZnO. These absorbance are compared with the initial drug's absorbance. Some parameters which are effected on the rate of photocatalytic oxidation are studied in present research such as the amount of catalyst, initial concentration for the drug's solution, pH and the temperature for the drug's solution. The results show that the photocatalytic oxidation reaction for the paracetamol and procaine obey pseudo - first order according to the Langmuir - Hinshelwood relationship, and also it is found that the photoctalytic oxidation rate fits positively with the increase of the catalyst weight until the weights of ZnO equal to 0.025 g and 0.1 g are considered the optimum weights for paracetamol and procaine respectively where the best photocatalytic degradation is happened. So after these values, the photocatalytic degradation rate is decrease or stablized with the increase of the catalyst weight. In addition, the initial concentration increase for both drugs leads to reduce degradation rate. Also this study is found the increase of pH of reaction solution for both drugs has a positive effect represented by increasing the degradation rate until the pH 8 and 4 are the best acidic function of the paracetamol and procaine respectively. Regarding the change of the temperature has a little effect on the rate of photocatalytic degradation and it was noticed that the reaction rate increases with the increase of temperature. Activation energy is calculated according to the Arrhenius plot of lnK vs. 1/T, the slop of linear plot is equal to ( - Ea/R). Activation energy was found equal to 7.96 KJ. mol - 1 for paracetamol and 8.71 KJ. mol - 1 for procaine. The thermodynamic functions are calculated in current study for each drug and the results for paracetamol are as following : ?G = 63.61 ± 2.85 KJ.mol - 1?H = 5.40 ± 0.13 KJ.mol - 1?S = - 0.189 KJ.K - 1.mol - 1And the results of procaine are as following : ?G = 63.43 ± 2.81 KJ.mol - 1 ?H = 6.15 ± 0.13 KJ.mol - 1?S = - 0.186 KJ.K - 1.mol - 1The results of the suggested mechanism of degradation are shown that the final products for degradation are CO2, H2O and mineral acids.
