Diarrheal disease, characterized by the release of more than three loose or liquid stools per day, remains one of the leading causes of morbidity and mortality in children below 5 years of age in developing countries. Many drugs used in diarrhea management face contraindication and, with regard to infectious diarrhea, resistance of some bacterial strains; this therefore increases the need of new alternative and more effective drugs. This study aimed to evaluate anti-Shigella flexneri activities of Crinum jagus water/ethanol extract. In vitro activities were assayed by disc diffusion and agar dilution methods and in vivo section on Shigella flexneri-induced diarrhea in rats. This was done by oral administration of 9 X 108 CFU of Shigella flexneri to rats that were treated twice daily with Crinum jagus water/ethanol extract for seven consecutive days. Ciprofloxacin was used as positive control. Daily Shigella flexneri load was evaluated. After one treatment week, animals were then sacrificed and interleukins (IL-2 and INF-γ), immunoglobulins (IgA and IgM), motilin, vasoactive intestinal peptide, and ions (sodium, potassium, calcium, and chloride) levels were determined. Also, blood cell count was realized. Crinum jagus water/ethanol extract dose-dependently inhibited Shigella flexneri growth with inhibition diameter of 18.90 and 25.36 mm, respectively, at 0.39 and 200 mg/mL. Minimum inhibitory concentration (MIC) was 0.10 mg/mL and minimum bactericidal concentration (MBC) was 0.30 mg/mL with MBC/MIC ratio of 3.0. In Shigella flexneri-induced diarrheic rats, Crinum jagus reduced (p<0.01) diarrheal stools emission and Shigella load and lowered IL-2, INF-γ, IgA, IgM, and motilin blood levels, whereas it increased (p<0.01) vasoactive intestinal peptide, sodium, potassium, calcium, and chloride blood levels. In diarrheal rats, Crinum jagus restored the decreasing white blood cells and haemoglobin and restored the damaged colon epithelium, where it reduced the density of mucus-filled goblet cells. These results confirm the use of Crinum jagus in ethnomedicine in diarrhea treatment.

Mung bean seed coat (MBSC) is a healthcare product in Asian countries. The aim of this study was to investigate the effect of an MBSC ethanol extract on the bioavailability of cyclosporine A (CsA) in rats. Rats were orally dosed with CsA alone or in combination with MBSC ethanol extracts (500 mg/kg, p.o.). The blood levels of CsA were assayed by liquid chromatography with an electrospray ionization source and tandem mass spectrometry (LC-MS/MS). The everted rat intestinal sac technique was used to determine the influence of MBSC on the absorption of CsA. The results reveal that combined CsA intake with MBSC decreased the Cmax, AUC0-t, t1/2z and MRT0-t values of CsA by 24.96%, 47.28%, 34.73% and 23.58%, respectively (P<0.05), and significantly raised the CL/F by 51.97% (P<0.01). The in vitro results demonstrated that significantly less CsA was absorbed (P<0.05). The overall results indicate that after being concomitantly ingested, MBSC reduced the bioavailability of CsA, at least partially, in the absorption phase.

Kegunaan labu kuning di Indonesia masih sebatas daging buah yang dapat diolah menjadi panganan seperti kue basah, kolak dan sayur berkuah. Secara empiris, biji labu kuning telah digunakan untuk mengatasi cacingan. Penelitian ini dilakukan untuk mengetahui mortalitas cacing gelang (Ascaridia galli) dalam ekstrak etanol biji labu kuning (Cucurbita moschata Duchesne). Penelitian ini menggunakan 25 ekor Ascaridia galli yang dibagi menjadi 5 kelompok, kelompok I kontrol negatif menggunakan larutan NaCl fisiologis, kelompok II kontrol positif menggunakan larutan pirantel pamoat 0,5 %, kelompok III, IV dan V berturut-turut menggunakan 25 mg/ml, 50 mg/ml dan 100 mg/ml ekstrak etanol biji labu kuning. Parameter penelitian ini ditentukan dengan melihat persentase nilai skor pasca inkubasi 12 jam, 24 jam, dan 36 jam. Skor 3 diberikan apabila seluruh tubuh Ascaridia galli bergerak, skor 2 diberikan jika hanya sebagian tubuh Ascaridia galli bergerak, skor 1 jika Ascaridia galli diam tetapi masih hidup, dan skor 0 apabila Ascaridia galli mati. Hasil uji in vitro dengan perlakuan 25 mg/ml ekstrak etanol biji labu kuning menyebabkan kematian 3 ekor Ascaridia galli  atau 60% pasca inkubasi 36 jam, sedangkan ekstrak etanol biji labu kuning dengan perlakuan 50 mg/ml, 100 mg/ml dan kelompok kontrol positif mengakibatkan kematian 4 ekor Ascaridia galli atau 80% pasca inkubasi 36 jam. Dari hasil penelitian disimpulkan bahwa ekstrak etanol biji labu kuning (Cucurbita moschata Duchesne) dosis 25 mg/ml, 50 mg/ml, dan 100 mg/ml secara in vitro dalam waktu 36 jam mampu mengakibatkan mortalitas Ascaridia galli. The use of yellow pumpkin in Indonesia is still limited to fruit meat that can be processed into snacks such as soggy cakes, porridge and vegetable soup. This research was conducted to determine the mortality of Ascaridia galli in ethanol extract of yellow pumpkin seeds (Cucurbita moschata Duchesne). This study used 25 Ascaridia galli which were divided into 5 groups, group I was negative control using physiological NaCl solution, group II was positive control using 0.5% pirantel pamoate solution, group III, IV and V respectively used 25 mg / ml, 50 mg/ml and 100 mg/ml ethanol extract of yellow pumpkin seeds. The parameters of this study were determined by looking at the percentage of post-incubation scores 12 hours, 24 hours, and 36 hours. A score of 3 is given if the whole body of Ascaridia galli moves, a score of 2 is given if only part of the body of Ascaridia galli moves, a score of 1 if Ascaridia galli is still but still alive, and a score of 0 if Ascaridia galli dies. In vitro test results with 25 mg/ml ethanol extract of pumpkin seeds caused 3 deaths of Ascaridia galli or 60% after incubation for 36 hours, while ethanol extract of yellow pumpkin seeds treated with 50 mg / ml, 100 mg/ml and positive control group resulting in the death of 4 Ascaridia galli or 80% after 36 hours incubation. From the results of the study concluded that the ethanol extract of yellow pumpkin seeds (Cucurbita moschata Duchesne) doses of 25 mg / ml, 50 mg / ml, and 100 mg / ml in vitro within 36 hours can lead to Ascaridia galli mortality.

Sickle cell disorder is a genetic ailment with enormous social and economic burden for patients and caregivers. The most promising management apart from being expensive particularly for poor African people, faces some major incompatibility problems. The patients consequently rely on herbal therapy which could be prepared in single or combination forms to manage the painful episodes and its complications. This present study aimed to formulate polyherbal combination and evaluate three purposively selected plants previously reported for their antisickling activities. The polyherbal products were formulated using both aqueous and 70% ethanol extracts into different combinational ratio with the best in 1:1:1 and evaluated for its antisickling activity. The antisickling activity involved both the inhibitory and reversal effects at varying concentrations from 1.0 mg/ml to 6.0 mg/ml using ciklavit as the positive control. The best inhibitory activity was found in ethanol extract of Piper guineense, Gongronema latifolium and Cymbopogon citratus (PGC) with 70.09 ± 0.67% when compared with the positive control (59.25 ± 0.05%) at 4.0 mg/mg while the reversal ability was 67.87 ± 1.23%. The aqueous extracts of the combinations had activity above 50% with the exception of PGC (2:3:1) which is a little less than 50% (46.67 ± 0.98%) while the highest was 60.02 ± 0.87%. The polyherbal ethanol extract had better effects than the aqueous extract and the standard drug used in this study.

Introduction: Mahkota dewa (Phaleria macrocarpa) is an Indonesian fruit that contains antibacterial compounds, such as flavonoids, saponins, and tannins; it has been used as an alternative treatment for controlling infection. Objectives: This study aimed to examine the effect of mahkota dewa fruit extract on the formation of Porphyromonas gingivalis (P. gingivalis), Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans), and Treponema denticola (T. denticola) biofilms in vitro. Methods: God’s crown fruit was extracted using the maceration technique, and then diluted into different concentrations (25%, 12.5%, 6.25%, 3.125%, and 1.56%) using phosphate buffered saline (PBS). P. gingivalis ATCC-33277, A. actinomycetemcomitans ATCC-29522, or T. denticola ATCC-35405 were cultured in brain heart infusion (BHI) broth, 24h (anaerobic-condition), and then each type of bacteria (108CFU/mL) was distributed into a 96-well microplate to form a biofilm. Subsequently, the fruit extracts were distributed into the biofilm-containing well plates and incubated for 1h, 6h, and 24h. A biofilm without the fruit extract and chlorhexidine-gluconate (0.2%) was used as the negative and positive control, respectively. Crystal violet (0.5%w/v) was used to determine the density of the remaining biofilm using a microplate spectrophotometer (600 nm). Data were statistically analyzed using one-way ANOVA, and p <0.05 was set as the level of significance. Results: The mahkota dewa fruit extracts significantly inhibited the formation of a biofilm for all three bacterial strains at all concentrations and for each incubation time (p <0.05) based on optical density (OD)±SD.  The best concentration of fruit extract to inhibit biofilm formation was 25% for P. gingivalis (OD=0.19±0.06), 12.5% for A. actinomycetemcomitans (OD=0.14 ± 0.16), and 25% for T. denticola (OD=1.17±0.19) in comparison to the biofilm mass of the negative control, which was 1.67±0.06, 1.17±0.34, 2.66±0.38 for P. gingivalis, A. actinomycetemcomitans, and T. denticola, respectively. Conclusion: Based on these results, mahkota dewa fruit extract can inhibit the formation of biofilm on P. gingivalis, A. actinomycetemcomitans, and T. denticola, and it may potentially be used to prevent the infection associated with periodontal disease.

Physalia utriculus is one of the invertebrate marine biota that is often found in Indonesia. Some symptoms of venoming due to jellyfish stings cause pain, itching, and hemolysis. In Indonesia, 13 cases of jellyfish stings were reported in 2005-2009 with three people dying in Java, Bali, and Bangka. Cocoa beans (Theobroma cacao L.) contain fat, carbohydrates, proteins, and polyphenol compounds that are useful as antioxidants. Polyphenols in the form of epicathechins, catechins, and procyanidins serve to provide protection to hemolysis. The purpose of this study was to determine the potential of ethanol extract of cacao (Theobroma cacao L.) in inhibiting the damage of erythrocyte induced by Physalia utriculus in vitro. This study used 28 samples of erythrocytes divided into seven groups, namely the normal control group, negative controls, and treatment with cocoa ethanol extract 0.2%, 0.1%, 0.04%, and 0.02%. Each subsequent group induced venom Physalia utriculus. The results showed that the average speed of erythrocyte lysis in the treatment group by giving cocoa ethanol extract 0.2%, 0.1%, 0.04%, and 0.02% respectively (seconds ± standard deviation) was 858,25 ± 94,44; 1.000,5 ± 159,93; 678,5 ± 19,71; and 1.006 ± 159,50. The mean speed of erythrocyte lysis in the negative control group was 1,025 ± 164.63 and the positive control group with the administration of N-Acetylcystein can last up to one hour after administration of venoms. Test for normality and homogeneity shows that data is normally distributed and homogeneous. One Way Annova analysis shows the significance value of p <0.05, then a post hoc analysis test was performed with the Bonferoni method to find out the differences in significance in each group. In this study it can be concluded that the administration of cocoa ethanol extract has no potential to inhibit erythrocyte damage that has been venomed by Physalia utriculus in vitro. Keywords: Physalia utriculus, cacao, erythrocyte damage
