The effects of Carum copticum essential oil (CC EO) and thymol were assayed against fourth instar of Ephestia kuehniella Zeller by determining insecticidal activities and enzymatic responses. Concentrations of 5.42 and 6.81?μl/ml were obtained as LC50 values for CC EO and thymol, respectively. The activities of esterases, aminotransferases, aldolase, and lactate dehydrogenase significantly decreased in the treated larvae by CC EO and thymol. Significant increases in glutathione S-transferases, γ-glutamyl transferase, and phosphatases were observed after treatment. Results revealed that CC EO and thymol significantly influenced the enzymatic activities of E. kuehniella leading to disruption of survival and metabolic responses. 相似文献

Background:
The World Health Organization (WHO) defines mental health as “a state of well-being in which every individual realizes own potential, can cope with the normal pressures of life, is able to work effectively, and can make a contribution to community”.Objectives:
Mental Health Problems (MHP) is a great concern for all societies in terms of its burden and impact. This survey screened MHP and its impact in an Iranian urban population aged 6 - 12 years old, and explored its associated socio-familial factors.Patients and Methods:
The survey was conducted in the elementary schools of Semnan, using random cluster sampling. Collection and analysis of data was performed using the parent version of the “Strengths and Difficulties Questionnaire (SDQ)” and survey commands of Stata-nine, taking into account cluster effect and population weights. Associations were assessed by fitting simple and multiple logistic regression models. P < 0.05 was considered significant.Results:
With regard to the SDQ total score, 19.3% (95% CI: 8.6, 30.1) scored above the normal threshold (9.6% abnormal, 9.7% borderline). The frequency of problems ranged between 16.1% (peer problems) and 8.4% (emotional symptoms), and in all subscales boys were affected more than girls. The impact score was abnormal in 68.4% of all children, and was greater in girls than in boys. “A previously diagnosed mental health disorder” (OR = 11.11, 95% CI: 5.55, 25.00), “male gender” (OR = 1.43, 95% CI: 1.10, 1.87 and “less time spent with the child by father” (OR = 1.61, 95% CI: 1.20, 2.17) were significantly associated with an abnormal SDQ.Conclusions:
The high rate of MHP in 6 - 12 year-old children and the lack of any significant correlation with their age, underpins the importance of early screening for MHP in schools, with particular focus on high risk groups. 相似文献3.

Background
Countries in the Arab region lack a valid Arabic psychiatric diagnostic interview for children and adolescents. We set out to establish the diagnostic validity of the Arabic version of the Development and Well Being Assessment (DAWBA-Arabic), a multi-informant structured interview for predicting DSM-IV-TR diagnoses.Methods
The DAWBA was translated, updated, and administered to 45 participants (child and adolescent psychiatric outpatients and their parents) as part of a clinic registry. Two clinicians, blinded to their respective diagnoses, formulated the DAWBA diagnoses. Participants also underwent a clinical evaluation by a child and adolescent psychiatrist who generated clinical diagnoses according to the DSM-IV-TR.Results
Inter-rater reliabilities were .93, .82, and .72 for disruptive disorders, mood disorders and anxiety disorders respectively. Agreement between DAWBA and clinical diagnoses was substantial for disruptive disorders (κ = .0.82) and mood disorders (κ = 0.74), and moderate for anxiety disorders (κ = 0.46).Conclusion
The DAWBA-Arabic could serve as a valid and reliable clinical tool for assessing psychiatric disorders among children and adolescents in the Arab region. 相似文献5.

This study aimed at investigating the reliability and validity of the Arabic Screen for Child Anxiety Related Emotional Disorders (SCARED) as a first child and adolescent anxiety screening tool in the Arab World. The English parent (SCARED-P) and child (SCARED-C) versions were translated into Arabic and administered along with the Arabic Strengths and Difficulties Questionnaire (SDQ) to 77 parents and 67 children attending a Psychiatry clinic. DSM-IV-TR diagnoses were made by a psychiatrist without knowledge of the scale scores. Internal consistency was confirmed by Cronbach's α=0.92 for SCARED-P and 0.91 for SCARED-C. Their subscales had internal consistencies between 0.65 and 0.89. Parent–child agreement was r=0.67, p<0.001. SCARED-P demonstrated good discriminant validity between participants with anxiety disorders and those with other psychiatric disorders (t(72)=3.13, p=0.003). For SCARED-C, this difference was significant when participants with depressive disorders were excluded (t(43)=2.58, p=0.01). Convergent validity was evident through a significant correlation between SCARED-P and the parent SDQ emotional subscale (r=0.70, p<0.001), and SCARED-C and the child SDQ emotional subscale (r=0.70, p<0.001). Divergent validity with the SDQ hyperactivity subscale was observed as no significant correlation was found. Overall, the Arabic SCARED demonstrated satisfactory psychometric properties in a clinical sample in Lebanon. 相似文献

Neurons in the nucleus cuneiformis (CnF), located just ventrolateral to the periaqueductal gray, project to medullary nucleus raphe magnus (NRM), which is a key medullary relay for descending pain modulation and is critically involved in opioid-induced analgesia. Previous studies have shown that antinociceptive response of CnF-microinjected morphine can be modulated by the specific subtypes of glutamatergic receptors within the CnF. In this study, we evaluated the role of NMDA and kainate/AMPA receptors that are widely distributed within the NRM on morphine-induced antinociception elicited from the CnF. Hundred and five male Wistar rats weighing 250-300 g were used. Morphine (10, 20 and 40 microg) and NMDA receptor antagonist, MK-801 (10 microg) or kainate/AMPA receptor antagonist, DNQX (0.5 microg) in 0.5 microl saline were stereotaxically microinjected into the CnF and NRM, respectively. The latency of tail-flick response was measured at set intervals (2, 7, 12, 17, 22, 27 min after microinjection) by using an automated tail-flick analgesiometer. The results showed that morphine microinjection into the CnF dose-dependently causes increase in tail-flick latency (TFL). MK-801 microinjected into the NRM, just 1 min before morphine injection into the CnF, significantly attenuated antinociceptive effects of morphine. On the other hand, DNQX microinjected into the NRM, significantly increased TFL after local application of morphine into the CnF. We suggest that morphine related antinociceptive effect elicited from the CnF is mediated, in part, by NMDA receptor at the level of the NRM whereas kainite/AMPA receptor has a net inhibitory influence at the same pathway. 相似文献

OBJECTIVE: Clonidine-based therapies have been utilized as the main protocol for opiate detoxification for several years. However, detoxification with clonidine has its limitations, including lack of efficacy for mental symptoms. Accumulating evidence shows the efficacy of Passiflora incarnata extract in the management of anxiety. In our continuing study of traditional medicines, which have neurotropic effects, this plant had an anxiolytic effect, which may be used as an adjuvant agent in the detoxification of opiates by clonidine. We present the results of a double-blind randomized controlled trial of clonidine plus passiflora extract vs. clonidine plus placebo in the outpatient detoxification of 65 opiates addicts. METHODS: A total of 65 opiates addicts were assigned randomly to treatment with passiflora extract plus clonidine tablet or clonidine tablet plus placebo drop during a 14-day double-blind clinical trial. All patients met the DSM IV criteria for opioid dependence. The fixed daily dose was 60 drops of passiflora extract and a maximum daily dose of 0.8 mg of clonidine administered in three divided doses. The severity of the opiate withdrawal syndrome was measured on days 0, 1, 2, 3, 4, 7 and 14 using the Short Opiate Withdrawal Scale (SOWS). CONCLUSION: Both protocols were equally effective in treating the physical symptoms of withdrawal syndromes. However, the passiflora plus clonidine group showed a significant superiority over clonidine alone in the management of mental symptoms. These results suggested that passiflora extract may be an effective adjuvant agent in the management of opiate withdrawal. However, a larger study to confirm our results is warranted. 相似文献

Depression is a serious disorder in today's society, with estimates of lifetime prevalence as high as 21% of the general population in some developed countries. As a therapeutic plant, saffron is considered excellent for stomach ailments and as an antispasmodic, to help digestion and to increase appetite. It is also used for depression in Persian traditional medicine. Our objective was to assess the efficacy of the stigmas of Crocus sativus (saffron) in the treatment of mild to moderate depression in a 6-week double-blind, placebo-controlled and randomized trial.Forty adult outpatients who met the Diagnostic and Statistical Manual of Mental Disorders, 4th edition for major depression based on the structured clinical interview for DSM IV participated in the trial. Patients had a baseline Hamilton rating scale for depression score of at least 18. In this double-blind, placebo-controlled, single-centre and randomized trial, patients were randomly assigned to receive a capsule of saffron 30 mg[sol ]day (BD) (Group 1) or a capsule of placebo (BD) (Group 2) for a 6-week study. At 6 weeks, Crocus sativus produced a significantly better outcome on the Hamilton depression rating scale than the placebo (d.f. = 1, F = 18.89, p < 0.001). There were no significant differences in the two groups in terms of the observed side effects.The results of this study indicate the efficacy of Crocus sativus in the treatment of mild to moderate depression. A large-scale trial is justified. 相似文献
