Comparison of the effects of intrathecal administration of levobupivacaine and lidocaine on the prostaglandin E 2 and glutamate increases in cerebrospinal fluid: a microdialysis study in freely moving rats

Abstract: Spinal PGE(2) levels are similarly increased after i.t. levobupivacaine injection of 250 and 100 microg. A higher PGE(2) response was observed after a second i.t. injection in the animals receiving 1000 microg lidocaine than those receiving 400 mg lidocaine or either dose of levobupivacaine.

“…Lidocaine induced increased PGE 2 release in both cell types, but it was more evident on HaCaT cells. Our data are consistent with other in‐vivo previous studies that showed an increase in PGE 2 release after intrathecal injection of lidocaine . This effect was attributed to increased intracellular calcium levels induced by local anaesthetics, leading to activation of many enzymes, including phospholipase A 2.…”

“…Aktivitas imunostimulan ditunjukkan dengan peningkatan indeks organ hati, limpa, dan timus. 15 Gambaran mikroskopis pada penelitian ini adalah makrofag terutama berasal dari sel prekursor pada sumsum tulang, dari promonosit yang akan membelah menghasilkan monosit yang beredar dalam darah. Pada tahap kedua monosit bermigrasi ke dalam jaringan ikat tempat mereka menjadi matang dan inilah yang disebut makrofag.…”

“…6,13 Hasil pengamatan menunjukkan bahwa secara mikroskopis pada pembesaran objektif 100x terlihat sel makrofag eksudat peritoneal yang memfagositosis S. aureus (berwarna terang di dalam makrofag) setelah 1, 3, dan 6 jam>100 sel per lapang pandang. 15 Berdasarkan atas hasil pengamatan aktivitas fagositosis sel makrofag yang diinokulasi S. aureus memperlihatkan perbedaan jumlah sel makrofag yang memfagositosis bakteri dari setiap kelompok perlakuan dosis 220 mg/ kgBB, 110 mg/kgBB, 55 mg/kgBB, pembanding zymosan A dan kelompok kontrol (akuades). Hasil analisis statistik menunjukkan bahwa masing-masing ekstrak yang ditambahkan akan memberikan pengaruh yang bermakna terhadap peningkatan aktivitas fagositosis sel makrofag (p<0,05).…”
