ABSTRACT

Malaria remains one of the health problems that causes death in Indonesia. In the last 10 years, the resistance of malaria against chloroquine and Kina treatment is increasing, so we need alternative treatments using natural substances. Sambiloto herb is known to have some antimalarial active compounds. This study was a laboratoric experiment that aimed to determine which dose has the most excellent antimalarial activity in lowering the Plasmodium berghei density in Swiss- Webster mice. Twenty-five samples were divided into 5 groups, each of group was given a dose 0.5 mg/20 grams, 1.0 mg/20 grams, 1.5 mg/20 grams, 1 positive control, and 1 negative control. The increase of parasites density and the percentage of inhibition were calculated in each group. The normality data was tested using Shapiro-Wilk, the hypothesis test was analysed with Kruskal-Wallis, followed by analysis by Mann-Whitney. The results show that neither group of dose dose 0.5 mg/20 grams, 1.0 mg/20 grams, 1.5 mg/20 grams has antimalarial activity."

Background: Malaria is a world health problem, including Indonesia, with a fairly high number of cases and mortality. Currently, there is an increasing trend of resistance to first-line antimalarial drugs. Sambiloto (Andrographis paniculata) and spirulina (Arthrospira platensis) are two herbal plants that are widely available in Indonesia and are known to have antimalatial activity. Kusmardi et al’s study showed that giving a combination of sambiloto and spirulina extracts could reduce the inflammation focus in the colon media of mice infected with Plasmodium berghei ANKA.

Objective: This study aims to determine the effect of giving a combination of sambiloto and spirulina extract on the expression of COX-2 protein in the colon media of mice infected witth Plasmodium berghei ANKA.

Methods: Thirty male Swiss Webster mice infected with P. berghei were divided into five groups consisting of positive control (DHP), negative control (CMC), sambiloto extract (AP), combination of sambiloto extract and spirulina extract (AP+ES), and with spirulina powder (AP+PS). A total of five colon’s histological images were taken by microscope (400x) and analyzed using ImageJ® to obtain the percentage of the H Score COX-2 index value.

Results: Significant results were found between the DHP group with AP, AP+ES, and AP+PS (p<0.05). The mean number of COX-2 expression in the DHP group is 226.67, while in the AP, AP+ES, and AP+PS groups are 201.89, 203.22, and 204.9, respectively. There is no significant difference between the CMC group with DHP (p=0.7) and the CMC group with AP (p=0.875).

Conclusion: The administration of sambiloto extract and spirulina, either in single or in combination form, can reduce the level of COX-2 expression in the medial colon of mice infected with Plasmodium berghei ANKA."

Background: Malaria is still a major infectious disease in the world. Most of death in malaria are caused by cerebral malaria due to Plasmodium falciparum infection. Amaranthus spinosus L and Andrographis paniculata Burm.F were traditional herbs used to cure malaria. The aim of this study was to determine the anti-malarial effect of the combination of these two herbs in a malaria mouse model through the measurement of survival rate, body weight, MDA, GSH and brain histopathology of mice infected with Plasmodium berghei in vivo.

Methods: male mice (Swiss strain) weighing 28-30 g, 7-8 weeks were used for this study. Treatment animal groups: K. control (nil); I. control negative. II. combination treatment (10mg + 4mg/kgBW; once per day for 7 days); III. chloroquine treatment (10mg/ kgBW; once per day for 3 days). all treatment was administered per os.

Result: A combination of extracts of Amaranthus spinosus L and Andrographis paniculata Burm.F in mice infected with Plasmodium berghei increased the survival rate (100%) and the body weight (10%) of mice respectively. The MDA levels slightly lower than control, although not significantly different (0.112 ± 0,021 nmol/ vs. 0.133 ± 0,0145nmol/mg) (p ≥ 0.05), while GSH level increased significantly (0.003 ± 0,0005 µg/mg vs. 0.0002 ± 0,0001µg/mg) p ≤ 0.05. Histopathological analysis showed improvement of brain cells in mice given a combination of extracts."

"Malaria masih merupakan masalah kesehatan di dunia, termasuk Indonesia dengan angka kejadian setiap tahun mencapai 500 juta jiwa dan lebih dari satu juta diantaranya meninggal dunia. Munculya, strain Plasmodium yang resisten menjadikan pengobatan kurang efektif sehingga dibutuhkan bahan alami sebagai alternatif antiplasmodium. Flamboyan diketahui telah digunakan untuk pengobatan malaria, namun masih sedikit penelitian mengenai aktivitas antiplasmodium tanaman ini. Penelitian ini merupakan penelitian eksperimental dengan menggunakan ekstrak kulit batang dan ekstrak bunga Delonix regia yang dilakukan uji penapisan fitokimia dan uji aktivitas antiplasmodium secara in vivo pada mencit Swiss-webster yang diinfeksi Plasmodium berghei. Dari 24 sampel dibagi menjadi 8 kelompok perlakuan yang terdiri atas 3 kelompok ekstrak kulit batang dan bunga masing-masing dengan dosis 2,8 mg, 8,4 mg, dan 14 mg, serta 1 kelompok kontrol positif dan 1 kelompok kontrol negatif. Setiap kelompok perlakuan diamati densitas parasit dan dihitung persentase pertumbuhan dan persentase penghambatan yang terjadi. Data kemudian dilakukan uji normalitas dengan Shapiro-wilk dan uji hipotesis menggunakan One Way Anova dilanjutkan dengan uji Post Hoc. Hasil penelitian menunjukan kulit batang dosis 2,8 mg dan 8,4 mg menunjukan aktivitas antiplasmodium. Aktivitas antiplasmodium terbesar terjadi pada kulit batang dosis 8,4 mg sebesar 66,25% (p=0,314) diikuti kulit batang dosis 2,8 mg sebesar 38,88% (p=0,550).

Malaria is still a worldwide health problem, including Indonesia. Each year there are 500 million cases and more than one million people died. Resistant Plasmodium's strains makes the treatment less effective, therefore, discovery of natural substance as an alternative antiplasmodium treatment is necessary. Flamboyan is used to treat malaria, but only few research were done about it. This study is an experimental research using extract from Delonix regia's flower and bark. This study conducted phytochemical and antiplasmodium activity test using Swiss-Webster mice infected with Plasmodium berghei in vivo. From 24 samples, they were divided into 8 groups that consists of 3 groups of bark extracts and flowers, each with a dose of 2.8 mg, 8.4 mg, and 14 mg, 1 positive control and 1 negative control group. Each group were counted the percentage of growth and inhibition parasite density. The normality data is tested with Shapiro-Wilk and the hypothesis test using One Way ANOVA followed by Post Hoc test. The results showed extract of bark dose 2.8 mg and 8.4 mg have antiplasmodium activity. The greatest effect occured at dose of 8,4 mg with 66.25% (p=0,314) growth inhibition percentage, followed by bark dose's extract of 2,8 mg with 38,88% (p=0,550)."

"Kasus resistensi terhadap pengobatan malaria membutuhkan penemuan obat baru, salah satunya menggunakan ekstrak daun papaya (Carica papaya L.). Penelitian ini bertujuan mengetahui dosis paling efektif serta korelasi antara dosis dengan perubahan densitas parasit. Penelitian menggunakan desain eksprimental dengan pemberian tiga dosis ekstrak 9,75 mg; 15,50 mg; dan 21,25mg/20gBB kepada 25 mencit Swiss-webster. Data diolah menggunakan SPSS versi 16,00 dan dianalisis dengan uji Kruskall-Wallis yang dilanjutkan uji Post Hoc serta uji korelasi Spearman. Hasil penelitian menunjukan dosis kecil dan sedang berbeda bermakna (p<0,05) dengan kontrol negatif. Persentase penghambatan dosis kecil mencapai 99% dan ditemukan korelasi lemah antara dosis dengan densitas parasit. Dapat disimpulkan dosis 9,75 mg adalah yang paling efektif dengan terdapat korelasi antara peningkatan dosis dengan densitas parasit.

Increasing resistance against malaria treatment requires the discovery of new drugs, one of which uses papaya leaf extracts (Carica papaya L.). This study aims to determine the most effective dose and dose correlation between drug concentration and parasite density. This research is using eksperimental design by administering three doses of 9.75 mg extract; 15.50 mg; and 21.25mg/20gBW to 25 Swiss-Webster mice which were divided into three groups. Data was processed using SPSS version 16.00 and analyzed by Kruskal-Wallis test followed by Post Hoc test and Spearman correlation test.

The results showed that small and medium dose group were significantly different (p <0.05) compared to negative control group. Percentage inhibition small doses reached 99% and found a very weak correlation between the dose and the parasite density. It can be concluded that dose of 9.75 mg /20gBW is most effective with a weak positive correlation between the increase in dose to the density of parasites."
