Öz



Amaç: Günlük hayatta insanlar, bir bor bileşiği olan borik aside
maruz kalmaktadırlar. Bu çalışmada, düşük dozlarda uygulanan borik asidin
penisilin kaynaklı epileptiform aktivite üzerindeki etkisini araştırdık.
Ayrıca, borik asidin gabapentinin antikonvülsan etkisindeki rolünü de
inceledik.



Yöntem: Bu çalışmada, kırk sekiz adet erkek Wistar sıçanı kullanıldı.
Üretan anestezisinden sonra, sıçanlar stereotaksi aletine bağlandı.
Elektrokortikografi kayıtları için sol somatomotor korteks üzerine bir bipolar
elektrot sabitlendi. İlk deney setinde, intrakortikal penisilin (500 IU)
enjeksiyonundan 30 dakika sonra, dört farklı borik asit dozu (5, 10, 20 ve 40
mg/kg) intraperitoneal olarak uygulandı. İkinci deney setinde, borik asit (20
mg / kg), gabapentin (200 mg/kg) ve borik asit (20 mg/kg) + gabapentin (200
mg/kg) kombinasyonu uygulandı. İlaç enjeksiyonlarından sonra 120 dakika boyunca
elektrokortikografi kayıtları kaydedildi ve sonrasında spike frekans ve
amplitüdleri hesaplandı.



Bulgular: 5 mg/kg dozunda uygulanan borik asit, kontrol grubuyla
karşılaştırıldığında spike frekansını anlamlı ölçüde değiştirmedi. 10, 20 ve 40
mg / kg'lık dozlarında uygulanan borik asit ise, sırasıyla 50., 30. ve 30.
dakikalarda ortalama spike frekansını artırarak prokonvülsan aktivite gösterdi.
Gabapentin 30. dakikadan sonra ortalama spike frekansını azalttı. 20 mg/kg
dozunda uygulanan borik asit, gabapentinin antikonvülsan etkisini inhibe etti.
Spike amplüdü açısından hiçbir grup arasında anlamlı fark bulunmadı.



Sonuç: Bu çalışma, borik asidin düşük dozlarının penisilin kaynaklı
nöbetleri arttırdığını göstermektedir. Borik asit, bu 
prokonvulzan etkisini muhtemelen GABAerjik sistem üzerinden göstermektedir.

Objective: In daily life, people
are exposed to a boron compound, boric acid. 
This study was designed to investigate the effect of different low doses
of boric acid on penicillin-induced epileptiform activity.
The
role of
boric acid
in the anticonvulsant effect of gabapentin was also researched.

Method: Forty-eight Male Wistar rats were used in this study. After uretan anesthesia, rats were
attached to a stereotaxic device. A bipolar electrode was fixed over the left
somatomotor cortex for electrocorticography (ECoG) recordings. In the first set
of experiments, 30 min after intracortical injection of penicillin (500 IU),
four different doses of boric acid were received (5, 10, 20 and 40 mg/kg)
intraperitoneally (i.p.). In the second set of experiments, boric acid (20
mg/kg), gabapentin (200 mg/kg) and boric acid (20 mg/kg) + gabapentin (200
mg/kg) combination were administered. Electrocorticography recordings were
persisted for 120 minutes after the drug injections and spike frequencies and
amplitudes were calculated.

Results: Boric acid, at a dose of 5 mg/kg, did not
significantly change the means of spike frequency when compared to the control
group. At the doses of 10, 20 and 40 mg/kg, boric acid showed proconvulsant
activity by increasing the mean spike frequency in the 50, 30 and 30 minutes,
respectively. Gabapentin decreased the means of spike frequency in 30 min.
Boric acid (20 mg/kg) inhibited the anticonvulsant effect of gabapentin. No
significant difference detected between any groups in terms of spike amplitude.







Conclusions: The results of the present study show that low doses
of boric acid increase penicillin-induced seizures. We suggested that boric
acid may show its proconvulsant effect probably via GABAergic pathway.
