Objective : This study was conducted to investigate the effects of Hwangryunhaedok-Tang and Geongangbuja-Tang on the change of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) level induced by LPS I.C.V. injection in mice.
Method : We devided group into 6 mice and 6 mice were assingned to each group. In the normal group only saline was administered intragastrically, and in the control group LPS was injected intracerebroventricularly 1 hr after intragastric administration of saline. In the experiment groups Hwangryunhaedok-Tang(0.5g/kg, 1.0g/kg, 3.0g/kg) was administered intragastrically to mice 1 hr prior to LPS(100mg/mouse) I.C.V. injection.. Also Geongangbuja-Tang (0.5g/kg, 1.0g/kg, 3.0g/kg) was administered intragastrically to mice 1 hr prior to LPS(100mg/mouse) I.C.V. injection. To measure the plasma IL-6 and TNF-α level of mice, their blood samples were collected from retro-orbital plexus, immediately centrifuged at 4℃, and plasma was removed and stored frozen at -83℃ for later determination of IL-6 and TNF-α. The level of IL-6 and TNF-α production was measured by enzyme-linked immunosorbent assay in the plasma.
Result : Regarding IL-6 level, The 0.5g/kg and the 1g/kg groups of Geongangbuja-Tang decreased IL-6 level. Especially the 3g/kg control group decreased IL-6 level significantly than the normal group(p<0.01). Regarding TNF-α level, the 3g/kg group of Geongangbuja-Tang decreased it significantly(p<0.05).
Conclusion : These data revealed that Hwangryunhaedok-Tang might not have the anti imflammatory effect and Geongangbuja-Tang(3g/kg)might have the anti imflammatory effect by reducing the plasma IL-6 and TNF-α level in mice LPS Injection.EIM (Eighteen Incompatible Medicaments) is an important component in Oriental pharmacology and is directly related to clinical prescriptions. Medical practitioners argued that the definite cause and meaning of EIM was ambiguous and therefore debated the issue of clinical application of the EIM. This study conducted an in-depth literary research on the origin, meaning and contents of EIM with the purpose to contribute in its efforts to be used clinically. Even after thousands of years have past since establishment of Oriental medicine, EIM is still tabooed and was an obstacle that hindered ideologies. Modern herbal medicine texts claim that the use of EIM can reduce treatment effects and promote poisoning and side effects. However, since long ago, there has been medical practitioners who reject this as false. Recently, poisoning caused by EIM has been claimed to be from the toxicity of the drug itself, rather than the result of interaction between the drugs, and therefore they suggest that EIM is not a forbidden domain. In addition, EIM showed a difference in number depending on the era. However, this can be understood not as a definite number, but instead as a warning to be careful during combination of drugs for use as clinical medicine. Historically, there were very few cases in which EIM was used for clinical tests and thus, the clinical value is not, while others applied EIM directly to their bodies, which showed signs for the usefulness and potential of EIM for us. A more concrete and in-depth study must be made on EIM.
