Abstract

Citrus hystrix D.C. (kaffir lime) peel contains several flavonoids including rutin, naringenin, hesperidin. C. hystrix peel ethanolic extract (ChEE) has shown its potency as cardioprotector agent in chemotherapy. However, there  are  limitations  to  the  utilization  of  ChEE due to its  poor  water  solubility  and  low  oral bioavailability.  Accordingly,  self-microemulsifying drug delivery system (SMEDDS) formulations were developed to improve the oral absorption of flavonoids. Tween 80, Corn oil, and propylene glicol (5:1:1ml) were combined to form ChEE-SMEDDS. The present study is to evaluated ChEE-SMEDDS for their physicochemical  properties and in vivo using combination with doxorubicin to see blood serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), nitrit oxide (NO) activity and also cardio-hepato-histopathology of female Sprague Dawley rats. The results showed that ChEE-SMEDDS repaired cardio-hepato-histopathology profile of doxorubicin -induced rats, but did not reduce serum activity of NO, ALT and AST. These  results indicated that ChEE-SMEDDS has potency to be developed and improved as cardio-hepato-protector agent in chemotherapy.Keywords: Citrus hystrix D.C., SMEDDS, Cardio-hepatoprotector, Histopathology, Chemoterapy

Abstract

Doxorubicin is a chemotherapeutic agent that causes a lot of side effects in high doses. Thus, combination with a co-chemotherapeutic agent which can increase its toxicity on cancer cells, is needed to reduce its therapeutic dose. Red betel leaves (Piper crocatum Ruiz & Pav.) have been known to contain flavonoids and alkaloids that have anticancer activity. This study was conducted to determine the cytotoxic effect and apoptosis induction of red betel leaves methanolic extract (RBM), doxorubicin (dox) and the combination of them on WiDr cells as model of colon cancer. RBM was extracted by soxhlet method using methanol. Cytotoxicity assay was performed using MTT assay for both single and combination treatments for 24 hours to determine IC50 and CI as their parameters. Apoptosis induction was analyzed by double staining method using ethidium bromide-acridine orange staining. Treatment of RBM and dox on WiDr cells for 24 hours showed cytotoxic activity with IC50 100 μg/mL and 1.6 μM respectively. Combination of RBM and dox performed synergism effect with CI<0.9 (p<0.05). Combination of RBM (12.5 μg/mL) and dox (0.4 μM) increased the number of apoptosis cells compared to each single treatment. Based on this study, it can be concluded that red betel leaves methanolic extract is potential to be developed as a co-chemotherapeutic agent of doxorubicin on colon cancer but still need further study to disclose the underlying molecular mechanisms.Keywords :  Red betel leaves (Piper crocatum Ruiz & Pav.), doxorubicin, WiDr cells, co- chemotherapeutic agent

Abstract

DNA damage usually happens due to the several chemical materials that induce genotoxic effect in normal cells. Cinnamon essential oil (CEO), which contains cinnamaldehyde as its major compound, has been reported to possess antioxidant activity to prevent DNA damage. The aim of this study is to evaluate the genotoxic and cytotoxic effect of CEO on doxorubicin-induced Chinese Hamster Ovary (CHO-K1) cells. The cytotoxic effect of CEO was determined by MTT assay with the parameter of IC50 while the genotoxic effect was carried out by micronucleus (MN) assay by using acridine orange fluorescent staining with the parameter of MN/1000 cells reduction number. Based on MTT assay, CEO showed cytotoxic activity with the IC50 value of 30 μg/ml and for MN assay, 3 μg/ml (1/10 IC50) of CEO decreased the percentage of micronucleus per 1000 cells up to 94,55%. Thus, the result can be summarized that CEO does not induce genotoxic and has the potency to prevent DNA damage caused by doxorubicin on CHO-K1 cells.Keywords: genotoxic, cinnamomum essential oil (CEO), micronuclei assay, in vitro

Abstract

The usage of doxorubicin (DOX) as an anticancer drug in cancer patient may cause several side effects. One of that is cardiotoxicity by inducing the expression of nitric oxide synthase which may release nitric oxide (NO) resulting reactive oxygen species (ROS) in the cardiac. DOX needs to be combined with antioxidant since it could supressed ROS in the cardiac and reduce cardiomyopathy. Kelor (Moringa oleifera) is known as the source of antioxidant. This study aim to observe the treatment effects of ethanolic extract of kelor (EEK) on histopathology profile and concentration of NO in rats cardiac. The result from the hematoxylin-eosin staining showed that EEK improved the histopathology profile of rats’ cardiac. Compared with the DOX-only treatment, the structure of cardiac muscle cells treated by ethanolic extract of kelor is more well-arranged and the cells’ nucleus still visible. Concentration of NO was measured by cardiac puncture method. The result showed that the concentration of NO was decrease in line with increasing dose levels of EEK in combination with DOX. But at rats only given with EEK, the concentration of NO is quite high. In conclusion, EEK could be a cochemotherapy agent by reducing the cardiotoxicity effect of DOX.Keywords : doxorubicin, Moringa oleifera, nitric oxyde, histopathology
