[Analysing the contents of prostaglandins in gingival fibroblast and periodontal ligament cell by microspectrophotometer]
This investigation analyses the contents of prostaglandin E(2)(PGE(2)),6-keto-prostaglandin F(1a)(6-k-PGF(1a)) and thromboxane B(2)(TXB(2)) in gingival fibroblast (GF) and periodontal ligament cell(PDLC) by microspectrophotometer.The results showed that the absorbance of PGE(2) in GF was 0.25+/-0.03,the absorbance of 6-k-PGF(1a) was 0.20+/-0.03,there were significant difference between PGE(2),6-k-PGF(1a) and control group.The absorbance of PGE(2),TXB(2) and 6-k-PGF(1a) and control group.The absorbance of PGE(2),TXB(2) and 6-k-PGF(1a) in PDLC each were 0.20+/-0.20,0.16+/-0.03 and 0.13+/-0.02.They were much bigger than control group(0.07+/-0.01),which indicated prostaglandins in GF and PDLC can affect guided tissue regeneration and gingivitis degree,and there were important relationship between PG(s) in GF,PDLC and periodontitis.
