Diseases including Japanese encephalitis and filariasis can be transmitted to humans by Culex sp. Many methods could be applied to prevent their bites from reducing their population or preventing them from their bites. N, N-diethyl-meta-toluamide (DEET) has been widely used as an effective synthetic repellent, but DEET needs to be applied carefully, especially for children. Other repellents based on natural origin, i.e., Lavandula angustifolia D.C. (lavender) flower and Citrus reticulate L. (mandarin orange) peel essential oil and their combination with soybean oil, were studied in Parasitology Laboratory, Faculty of Medicine, Universitas Kristen Maranatha, Bandung on July–August 2018, for their repellent duration against female Culex sp. to find out the optimal formula. It is a simple randomized design with four replications and seven treatments, i.e., negative control, DEET, pure essential oil, pure soybean oil, three kinds of combination of essential oil and soybean oil in various ratios. The study was carried out using the arm in the cage method against four human arms, following Fradin and Day. The data were analyzed using ANOVA, continued with Tukey HSD with α=0.05. The result shows that DEET has the longest duration (p=0.000), the combination of each essential oil with soybean oil in 1:2 ratio had longer duration than the pure essential oil (p=0.000), soybean oil (p=0.000), and other combination ratios (p=0.000). It was concluded that a mixture of L. angustifolia D.C. flower/C. reticulata L. peel essential oil with soybean oil in a certain ratio was the ideal preparation to repel Culex sp. CAMPURAN MINYAK ATSIRI BUNGA LAVENDER/KULIT JERUK MANDARIN-MINYAK KEDELAI UNTUK MENOLAK CULEX SP.Beberapa penyakit termasuk Japanese encephalitis dan filariasis dapat ditransmisikan ke manusia melalui gigitan nyamuk Culex sp. Banyak cara dapat dilakukan untuk mencegah gigitan nyamuk ini, baik dengan mengurangi populasinya atau mencegah gigitannya. N, N-diethyl-meta-toluamide (DEET) telah digunakan secara luas sebagai repellent sintetik yang efektif, tetapi pemakaian DEET harus dilakukan dengan hati-hati khususnya pada anak. Repellent lain yang berasal dari alam, yaitu minyak esensial bunga Lavandula angustifolia D.C. (lavender) dan kulit buah Citrus reticulate L., serta campurannya dengan minyak kedelai telah diuji durasi proteksi terhadap Culex sp. betina sehingga diperoleh formula repellent yang optimal. Penelitian dilaksanakan di Laboratorium Parasitologi, Fakultas Kedokteran, Universitas Kristen Maranatha, Bandung pada Juli–Agustus 2018 dan menggunakan desain simple randomized dengan empat replikasi dan tujuh perlakuan, yaitu kontrol negatif, DEET, minyak esensial murni, minyak kedelai murni, dan tiga macam rasio campuran minyak esensial dengan minyak kedelai. Pengujian menggunakan metode lengan dalam kandang menurut Fradin dan Day dengan empat lengan sebagai empat replikasi. Analisis data menggunakan ANOVA, dilanjutkan Tukey HSD dengan α=0,05. Hasil penelitian menunjukkan bahwa DEET memiliki durasi proteksi paling lama (p=0,000), durasi proteksi kombinasi minyak esensial dengan minyak kedelai rasio 1:2 lebih panjang dibanding dengan minyak esensial murni (p=0.000), minyak kedelai (p=0.000), dan rasio kombinasi lainnya (p=0.000). Simpulan, rasio tertentu campuran minyak esensial bunga L. angustifolia D.C./kulit buah C. reticulata L. dengan minyak kedelai merupakan sediaan ideal untuk menolak Culex sp.

This study aimed to study whether alpha-mangostin could protect the kidneys of high-fat diet rats using the creatinine serum level and histopathological changes as parameters. The in vivo experimental study with a completely randomized design used 30 male Sprague Dawley rats. After 7 days of adaptation, they were randomly divided into six treatment groups, each with five replications. The study was done for four weeks: NC group (given standard pellet without treatment for four weeks), five other groups were given a high-fat diet for four weeks, and at the last two weeks were added with aquadest, corn oil, alpha-mangostin dose-1, alpha-mangostin dose-2, and simvastatin, namely PTL, CO, D1, D2, and Sim group. Creatinine level was examined at the end of week 2 and week 4; the difference percentage was analyzed using ANOVA/Kruskal Wallis (α=0.05) and continued with Duncan/Mann Whitney. It was shown that creatinine level decreased in D1/D2 = PTL mice (p>0,05); kidney histopathological image in D1 was better than PTL (p<0,05). It was concluded that the alpha-mangostin kidney protection effect was not yet visible according to creatinine level, but it was visible according to histopathological image; further studies are needed.

Introduction: Alphamangostin is a component of the mangosteen peel extract (Garcinia mangostana L) that has potential as a therapy for dyslipidemia. However, alphamangostin has low solubility, resulting in low bioavailability when administered orally. This study aims to investigate the potential of alphamangostin dissolved in corn oil on serum lipid profiles in vivo.Methods: The study was conducted on 24 Sprague Dawley strain Rattus norvegicus rats divided into 6 treatment groups (NC, HFD, CO, D1, D2, and Sim), with 4 rats each group randomly assigned. After a 1-week acclimatization period, each group received the following treatments: standard diet for 4 weeks (NC), high-fat diet + propylthiouracil (PTU) for 4 weeks (HFD), HFD + corn oil (CO), HFD + alphamangostin in corn oil at 7 mg/KgBW (D1), HFD + alphamangostin in corn oil at 35 mg/KgBW (D2), and HFD + simvastatin at 3.6 mg/KgBW (Sim). Treatments for CO, D1, D2, and Sim were administered for 2 weeks. Serum total cholesterol, HDL, LDL, and triglycerides were examined before and after treatment, and the differences were analyzed statistically.Results: The administration of alphamangostin at a dose of 7 mg/KgBW (D1) and corn oil (CO) significantly decreased LDL cholesterol levels (p less than 0.05), and alphamangostin at a dose of 35 mg/KgBW (D2) significantly decreased triglyceride levels (p less than 0.05). Meanwhile, there were decreases in total cholesterol levels and increases in HDL cholesterol levels in the alphamangostin and corn oil groups, but these changes were not statistically significant (p greater than 0.05).Conclusions: Alphamangostin can reduce LDL cholesterol and triglyceride levels in high-fat diet-induced rats.

Culex sp. can transmit diseases such as encephalitis and filariasis which is a public health problem because of elephantiasis, disability, and a neglected tropical disease. To prevent these diseases, the mosquitoes need to be eradicated and larvicides are considered to control them at their early stage. Temephos, a synthetic larvicide, could cause several disadvantage, such as potential toxicity against non-target organisms and easierto-develop mosquito resistance. Botanical sources from Indonesian spices i.e. galangal (Alpinia galanga (L.) Willd.) and basil (Ocimum sanctum L.) are potentially used as larvicide. This study aimed to explore the larvicidal effect of their essential oils compared against temephos against Culex sp. A true experimental study was done using several concentrations and replications of these essential oils in each container, consisting of 25 third instar of Culex sp larvae for 24 hours at room temperature according to WHO procedure. The percentage of dead larvae was analyzed by ANOVA/ Kruskal Wallis. The study showed that Alpinia galanga ( L.) Willd. and Ocimum sanctum L. essential oils had larvicide activity and their activity starting from 140 ppm and 400 ppm consecutively was the same as temephos 1 ppm.

Malaria drug resistance, including to development of resistance against artemisinin based treatments, poses a major challenge to elimination efforts. Alpha-mangostin, an antioxidant with in vitro antimalarial activity, is hindered by its poor solubility. This study explores the antimalarial effects of water-soluble alpha-mangostin chitosan-alginate nanoparticles (ACAN) in mice with berghei malaria. Mice were treated with various doses of ACAN, compared to alpha-mangostin in polyethylene glycol (PEG), as well as in corn oil (ACO) and chloroquine as a standard. Growth inhibition rates were assessed, revealing no inhibition in the PEG and normal control (NC) groups, while ACO was less active. The effective dose 50 (ED50) of ACAN was 264.5 mg/kg BW, containing only 15.87 mg of alpha-mangostin, suggesting that alpha-mangostin in ACAN may offer promising in vivo antimalarial activity. Further investigation is needed.
