Objectives : This study was aim to evaluate effects of pharmacodynamics and toxicity in combination therapy of donepezil with Gongjindan. Methods : After 10mg/kg of donepezil treatment, Gongjindan 100mg/kg was administered within 5 min. The plasma were collected at 30min before administration, 30min, 1, 2, 3, 4, 6, 8 and 24hrs after end of Gongjindan treatment, and plasma concentrations of donepezil were analyzed using LC-MS/MS methods. PK parameters of donepezil were analysis as compared with donepezil single administered rats. Results : Gongjindan markedly inhibited the absorption of donepezil regardless of sample time, from 30min to 8hrs after end of co-administration comparing with donepezil single treated rats. Especially the absorption of donepezil was significantly decreased at 2hrs after co-administration as compared with donepezil single treated rats, in the present study. Accordingly, the Cmax(-27.76%), $AUC_{0-t}$(-27.22%) and $AUC_{0-inf}$(-26.54%) of donepezil in co-administered rats were significantly decreased as compared with donepezil single treated rats, respectively. Conclusions : Based on the results of the present study, co-administration of Gongjindan decreases the oral bioavailability of donepezil by inhibiting the absorption. It is considered that the more detail pharmacokinetic studies should betested to conclude the effects of Gongjindan on the pharmacokinetics of donepezil, when they were co-administered, like the effects after co-administration with reasonable intervals considering the Tmax of donepezil and after repeated co-administrations.

Purpose : This study was aim to evaluate effects of pharmacodynamics and toxicity in combination therapy of donepezil with Gongjindan. The effects of Gongjindan co-administration on the pharmacokinetics (PK) of donepezil were observed after single and 7-day repeated oral co-administration with 1.5hr-intervals, to evaluate synergic pharmacodynamics and reduce toxicity of combination therapy of donepezil with Gongjindan. Materials and Methods : After 10mg/kg of donepezil treatment, Gongjindan100mg/kg was administered with 1.5hr-intervals. The plasma were collected at 30min before administration, 30min, 1, 2, 3, 4, 6, 8 and 24hrs after end of first and last 7th donepezil treatment, and plasma concentrations of donepezil were analyzed using LC-MS/MS methods. Results : Gongjindan markedly inhibited the absorption of donepezilregardless of sample time, from 30min to 8hrs after end of first 1.5hr-interval co-administration as compared with donepezil single treated rats. Especially the absorption of donepezil was significantly decreased at 2, 4, 6 and 8hrs after co-administration as compared with donepezilsingle treated rats. Accordingly, the Cmax (-26.236%), $AUC_{0-t}$(-26.02%) and $AUC_{0-inf}$(-25.90%) of donepezil in 1.5hr-interval co-administered rats were dramatically decreased as compared with donepezilsingle treated rats, respectively. However, no meaningful changes on the plasma donepezil concentrations and pharmacokinetic parameters were detected after end of last 7th 1.5hr-interval co-administration as compared with donerezil single treated rats, except for non-significant slight increases of Tmax(16.67%) detected in co-administered rats as compared with donepezil single treated rats. Conclusion : These findings are considered as direct evidences that Gongjindan also decreased oral bioavailability of donerezil as inhibited the absorptions, when they were co-administered with 1.5hr-intervals, but they may be adapted after 7 days continuous repeated l.5hr-interval co-administration.

Objective : In the previous study, co-administration of Gongjindan-gamibang (GJD) with sorafenib increased oral bioavailability of sorafenib through augment the absorption, therefore, the effects of GJD co-administration on the pharmacokinetics of sorafenib were observed after single and 7-day repeated oral co-administration with 3.5 hr-intervals in the present study. Method : After 50 mg/kg of sorafenib treatment, GJD 100 mg/kg was administered with 3.5 hr-intervals. The plasma were collected at 30 min before administration, 30 min, 1, 2, 3, 4, 6, 8 and 24 hrs after end of first and last 7th sorafenib treatment, and plasma concentrations of sorafenib were analyzed using LC-MS/MS methods. PK parameters of sorafenib ($T_{max}$, $C_{max}$, AUC, $t_{1/2}$ and $MRT_{inf}$) were analysis as compared with sorafenib single administered rats. Results : GJD markedly inhibited the absorption of sorafenib, from 1 hr to 24 hrs after end of first 3.5 hr-interval co-administration, the $C_{max}$ (-43.27%), $AUC_{0-t}$ (-56.29%) and $AUC_{0-inf}$ (-66.70%) of sorafenib in co-administered rats were dramatically decreased as compared with sorafenib single treated rats. However, GJD significantly increased the absorption of sorafenib, from 4 hr to 8 hrs after end of last 7th 3.5 hr-interval co-administration, the $AUC_{0-t}$ (34.08%) and $AUC_{0-inf}$ (37.31%) of sorafenib in co-administered rats were dramatically increased as compared with sorafenib single treated rats. Conclusion : Although GJD decreased the oral bioavailability of sorafenib through inhibition of gastrointestinal absorptions after end of first 3.5 hr-interval co-administration, it is observed that GJD increases the oral bioavailability of sorafenib as facilitated the absorption after end of last 7th repeated co-administration. Hence, the co-administration of GJD and sorafenib should be avoided in the combination therapy of sorafenib with GJD on anticancer therapy.

Objective : The co-administration effects of Gongjindan (GJD) on the pharmacokinetics (PK) of sorafenib were observed as a process of the comprehensive and integrative medicine. Methods : After sorafenib treatment, GJD was administered within 5 min. The plasma were collected at 30min before administration, 30min, 1, 2, 3, 4, 6, 8 and 24hrs after end of GJD treatment, and plasma concentrations of sorafenib were analyzed using LC-MS/MS methods. PK parameters of sorafenib ($T_{max}$, $C_{max}$, AUC, $t_{1/2}$ and $MRT_{inf}$) were analysis as compared with sorafenib single administered rats. Results : The absorption of sorafenib were significantly increased at 30min, 1, 6 and 6hrs after co-administration with GJD as compared with sorafenib single treated rats. Accordingly, the $AUC_{0-t}$ (47.20%) of sorafenib was significantly increased but $t_{1/2}$ (-30.63%) and $MRT_{inf}$ (-34.11%) in co-administered rats were non-significantly decreased. These findings are considered as direct evidences that GJD increased the oral bioavailability of sorafenib through increase of the absorption, when they co-administered within 5min. Conclusion : Based on the results, co-administration of GJD increased the oral bioavailability of sorafenib through increase of the gastrointestinal absorption. It is considered that the more detail pharmacokinetic studies should be tested to conclude the effects of GJD on the pharmacokinetics of sorafenib, when they were co-administered, like the effects after co-administration with reasonable intervals considering the $T_{max}$ of sorafenib (about 3.5hr-intervals) and after repeated co-administrations.Hence, concomitant uses of GJD with sorafenib may require close monitoring for potential drug interactions.

갱년기의 여성에는 여러 폐경 증후들이 나타나는데, 특히 에스트로겐의 감소로 인한 혈중의 지질 조성의 변화 등으로 골다공증 및 심혈관계 질환의 발병율이 높아지게 된다. Estrogen의 감소는 다양한 생리적 변화를 초래하며 특히 심혈관계 질환을 빠르게 진행시킨다고 보고되고 있다. 본 연구에서는 에스트로겐 유사활성이 뛰어난 갈조류를 선정하여 해조공진단을 제조하였으며, 실험동물인 흰쥐의 난소를 절제하여 인위적으로 갱년기를 유도한 후 해조공진단이 혈소판 응집능 및 혈중 지질 함량에 미치는 영향을 검토하였다. 에스트로겐 검출시스템을 사용하여 공진단 및 갈조류 추출물의 에스트로겐 유사활성을 검증한 결과, 다시마 및 곰피 열수 추출물에서는 통계적으로 유의한 에스트로겐 유사활성이 나타났으며, 특히 다시마 열수 추출물에서 가장 높은 활성이 나타났다. 이러한 in vitro 실험 결과를 통해 다시마 추출물을 첨가한 해조공진단을 제조한 후, 갱년기를 유도한 실험동물에 투여하여 혈소판 응집능 및 혈청 내 지질 조성에 미치는 영향을 검토하였다. 총 콜레스테롤 함량은 해조공진단 투여로 인해 OVX-CON군에 비해 감소하는 경향을 나타내었으나 유의적인 결과가 나타나지 않은 반면, 혈청 중 중성지방 함량의 경우, 해조공진단을 투여한 OVX-GJD군은 OVX-CON군과 비교하여 중성지방 함량이 유의적으로 감소하는 결과가 나타났다. 혈청 중 HDL-콜레스테롤 농도는 정상군인 SHAM군에 비해 난소를 절제한 OVX-CON군이 유의적으로 감소하였으나, 해조공진단을 첨가한 사료 섭취군(OVX-GJD)은 OVX-CON군에 비해 유의적으로 증가하는 결과를 나타내었다. 또한, 혈소판 응집 저해능을 검토한 결과에서 OVX-CON군에 비해 OVX-GJD군의 혈소판 응집이 유의적으로 감소하여 저해하는 경향을 나타내었다. 따라서 본 연구를 통해 제조된 해조공진단이 에스트로겐 유사활성을 가지고 있으며, 난소절제로 갱년기를 유도한 실험동물에게 이를 섭취시킨 결과 혈중 지질 개선 및 혈소판 응집 저해 효과가 나타나 갱년기 증상 완화에 활용 될 수 있는 소재로 기대된다.
