Abstract

Primary brain tumors consist are a heterogenic group of malignancies. Gliomas represent subtypes which include all tumors arising from glial cells. The risk factors for gliomas are until today unclear. The aim of this study was to summarize all possible connections between suspected risk factors and glial brain tumors.

Abstract

Aim: This study want to demonstrate the efficaciousness of drotaverinum as a replacer of papaverine in the prevention and treatment of vasospasm.

Material and method: In this study were used 20 albino Wistar male rats. Rats were divided in two groups and vasospasm was induced to the both femoral artery and after that irrigation of the femoral arteries with drotaverinum was performed to demonstrate the vasodilatation that can appear (group A). In the group B after the obtaining of vasospasm irrigation of the femoral arteries with saline solution was performed and this group was used as witness. The length of the vessels was measured when was achieved the vasospasm and also before and after the administration of the solutions. Pictures were taken at every step of dissection and solutions administration to can measure the length of arteries before and after the administration of drotaverinum and the saline solution.

Results: In all rats was obtained vasospasm at the femoral artery after clipping the artery and after we irrigate with adrenaline. In the group with drotaverinum we obtained the vasodilatation and in the witness group the caliber of the vessels remain the same. The statistical analysis of the data demonstrate a significant differences between the group were was used drotaverinum and the witness group were was used the saline solution (p<0,001).

Conclusions: Drotaverinum has a good vasodilatative effect on arteries and he can prevent the apparition of vasospasm and it can even treat vasospasm if occur by producing local vasodilatation and a good circulation in the area where is administrated. This study showed quantitatively that drotaverinum can treat the experimental peripheral vasospasm in rats.

Abstract

From an oncological perspective, the second most common malignancies in children are brain tumors. Despite the recent therapeutic breakthroughs in this field, concerning surgery, radiotherapy and chemotherapy alike, some cases still have poor outcomes in curability. This is especially the case in patients with high-risk histological types of tumors, and those suffering from residual, remitting and disseminated diseases. Due to the unique neuroanatomical emplacement of brain tumors and their aggressive infiltrative behavior, their total removal remains a demanding task. This can be perceived in the high rates of failure treatment and disease recurrence. Furthermore, the adjacent healthy brain tissue is inevitably damaged in the surgical process of effectively removing these tumors. Thus, stem cell transplantation may be a viable solution for the clinical management of these malignancies, as proven by various recent breakthroughs. In the current concise review, we present the role of next generation sequencing in HLA typing for stem cell transplantation in primary CNS pediatric malignancies.
