Şizofrenide Endorfin ve Prostaglandin Hipotezi
ZS Ercan
Prostaglandinler (PG), siklopentan karboksilik asit yapısında, prekürsör yağ asitlerinden sentez edilip, süratle hedef organlarda ya da lokal olarak yıkılan bileşiklerdir. Merkezi sinir sisteminde değişik dozlarda sedasyon ve öfori yapıcı etkileriyle beraber, vücut ısısının ve yemek yemenin regülasyonunda da görev alır. PG’lerin nöromodülatör görevleri vardır. Psikiyatrik bozuklukların da değişik nörotransmiter anormalliklerinden kaynaklandığı düşünülürse, adı geçen bozukluklarda PG’lerin etkin bir rol alabileceği öngörülebilir. Nitekim pek çok araştırıcı şizofrenide bir prostaglandin defekti olduğunu düşünmektedir. Bu düşünce şizofreniklerde azalmış PG fonksiyonuyla, bu hastaların trobbositlerinde azalmış PG etkinliği yönünde bulgu veren çalışmalara dayandırılmıştır. Bu çalışmanın amacı PG’lerle şizofreni arasındaki ilişkiyi incelemektir.
Endorphin and Prostaglandin Hypothesis in Schizoprenia
The prostaglandins (PGs) are cyclopentane carboxylic acids which are synthesized from precursor fatty acids and are rapidly metabolized both locally and in distant organs. In the CNS various effects of PGs are sedation, euphoria, alteration in body temperature and food intake. The potential neuromodulatory role cf PGs is of obvious relevance to psychiatric disorders with putative neurotransmitter abnormalities. Many investigators subsequently proposed that there is a PG deficiency in schizophrenia. This conception was based on the datal of the investigations consistent with decreased PG function in schizophrenics and also on the investigation of PG activity' in schizophrenic’s platelets. This study was aimed to report here the relation between PGs and schizophrenia.
