Abstract

Doxorubicin is one of chemotherapeutic agent used for cancer therapy. However, doxorubicin usage causes some adverse effects, such as lymphocyte, CD4+ and CD8+ cells number. Therefore, the co-chemotherapeutic agent is required to reduce the imunosuppression effect. Cardamom (Elettaria cardamomum) contains terpenoid 1,8 cineol. This research aimed to know the effect of Elettaria cardamomum distillate (ECD) in combination with doxorubicin on Sprague Dawley rat’s hematology profile and the amount of CD4+ and CD8+ cells. The experiment was done for 13 days using 6 groups of rats: I doxorubicin (dox) 15 mg/kg BW; II dox + ECD5 mg/kg BW; III dox + ECD 50 mg/kg BW; IV dox + ECD 100 mg/kg BW; V ECD 100 mg/kg BW; VI control without treatment. The hematology profile and the amount of CD4+ and CD8+ were counted before and after treatment using flowcytometer. The results show that ECD increases the amount of lymphocyte, white blood, CD4+ and CD8+ cells in dose dependent manner in doxorubicin treated rats. Based on the data, it can be concluded that ECD is potential to be developed as immunostimulant agent for chemotherapy.Keywords: Cardamom (Elettaria cardamomum), immunostimulant, hematology, CD4+, CD8+

Abstract

5-Fluorouracil (5-FU) is the first line chemotherapeutic agents for colon cancer therapy. Long term used of 5-FU caused cancer cell resistency. Thus, co-chemoteraputics agent should be developed to increase cells sensitivty towards 5-FU. Jure leaf  (Nerium indicum Mill) extract (JLE) contains oleandrin which has cytotoxic effect on colon cancer cell. The ain of this study was to investigated the mechanism of JLE to sensitized colon cancer cell toward 5-FU through NF-κB inhibition and MRP protein repression. JLE was extracted by soxhletation method. Based on molecular docking to MRP protein, docking score of oleandrin (-50,496)  was higher than native ligand ATP (-125,817). Oleandrin could interfere interaction with MRP. JLE increased 5-FU sensitivity a dose of 2 µg/mL JLE dan 12,5 µM 5-FU with the combination index (CI) of  0,594. Combination of JLE and 5-FU also inhibit p65 protein expression on WiDr cell.Keywords: cytotoxic, Nerium indicum Mill., oleandrin, immunofluorescence, molecular docking
