Antitumoral Effects of Curcumin (Curcuma longa L.) and Thymoquinone (Nigella sativa L.) on Neuroblastoma Cell Lines.

INTRODUCTION: Overall survival of high-risk neuroblastoma patients is still poor, emphasizing the need for novel therapeutic options. There is evidence for anti-cancer properties of the herbal substances thymoquinone and curcumin. These substances are isolated from Nigella sativa L. and Curcuma longa L., respectively, which are used in traditional medicine. OBJECTIVE: We investigated cytotoxic effects of thymoquinone and curcumin on neuroblastoma cell lines NLF, NB69, and SK-N-BE(2), in vitro. METHODS: Cytotoxicity of compounds was investigated by MTT cell viability assays. For analyzing effects on cell proliferation BrdU assays were employed and induction of apoptosis was detected by Cell Death ELISA assays. RESULTS: Both substances showed cytotoxic effects in all three neuroblastoma cell lines, whereby primary human fibroblast cells reacted less sensitively. Overall, lower IC50 values could be calculated for curcumin (3.75-7.42 µM) than for thymoquinone (5.16-16.3 µM). Decreased proliferation and increased apoptosis rates were observed under treatment. CONCLUSIONS: Both substances showed anti-tumoral properties on neuroblastoma cell lines and should be further investigated as therapeutic agents.

[In-patient treatment concept for acute crises of borderline patients on the basis of dialectical-behavioral therapy]. / Stationäres Interventionskonzept auf Basis der Dialektisch-Behavioralen Therapie zur Behandlung akuter Krisen bei Borderline-Patienten.

Whereas the Dialectical-Behavioral Therapy (DBT) by Marsha Linehan for chronic suicidal female patients with borderline personality disorder has also been successfully implemented for in-patient treatment, the management of recurrent crisis has continued to be a significant challenge especially for hospitals taking part in the mandatory health coverage. Therefore, we have established an acute, short-term crisis treatment concept for both genders on a locked unit which takes the different circumstances of acute crisis into account. It ought to be used under the conditions of acute psychiatry and at the same time meet psychotherapeutic demands of borderline treatment. The treatment basis is DBT. The treatment focus is to improve stress-tolerance, especially by skills-training, regarding the individual situation and problems at time of admittance. The in-patient treatment should not take more than three weeks. The short-time aim is a fast reintegration in ambulant treatment or motivation for a specific therapy as DBT, middle- and long-time aims are the improvement of the ability to cope with crises and to demand less in-patient care.
