Abstract High blood cholesterol is often called hypercholesterolemia is a risk factor for the emergence of pathological conditions such as heart and blood vessel disease. Hypercholesterolemia has an important role in the occurrence of damage to the endothelial cells is mainly caused by oxidized LDL. Oxidation of LDL triggers the formation of TNF - ?. Leaves messengers that allegedly contains flavonoids can improve the situation of hypercholesterolemia through the barriers specifically the expression of TNF - ? increased due to hypercholesterolemia. Plants messengers known to contain alkaloids, flavonoids, tannins, saponins, polyphenols, calcium oxalate, fats, and essential oil. Flavonoids which has the ability to bind the atom to form free radicals not to excess free radicals, thereby inhibiting the oxidative modification of LDL become ox-LDL so it will not be formed atherosclerosis. This study uses the Randomize pattern Pre and Post Test Control Group Design, using white rats (Rattusnovergicus) with Wistar strain aged 3-4 months, weighing 175-200 grams. Divided into four groups: Group I as a control with placebo, Group II treatment using extracts of ethanol leaves a messenger at a concentration of 10%, Group III treatments using extracts of ethanol leaves a messenger at a concentration of 20%, Group IV is to use the extract ethanol leaves errand at a concentration of 30%. It can be concluded at 4 dose group 30% messengers leaf extract significantly different, p <0.05, so it can be said that the provision of effective messengers extract at a dose of 30%.

ABSTRACT Background: In diabetes mellitus, hyperglycemia causes oxidative stress that enhances the production of free radicals. The presence of higher levels of malondialdehyde (MDA) indicates the rise of free radicals. On the basis of its role as an antioxidant that binds free radicals and reduces the level of malondialdehyde (MDA). Soursop leaf can act as an antidiabetic agent. This study aimed to examine the efficacy of soursop leaf extract (Annona muricata L.) to decrease the level of MDA level in alloxan-induced diabetic rats (Rattus norvegicus). Subjects and Method: This was an experiment study using pre- and pro-test with control group design. Total of 30 rats were selected for this study and divided into five groups of treatment i.e. group I was given distilled water and standard feed (Negative Control/KI), group II was given vitamin E 150 IU/kgBW/day (Positive Control/KII), group III was given soursop leaf extract 75 mg/kgBW/day (KIII), group IV was given soursop leaf extract 150 mg/kgBW/day (KIV), and group V was given soursop leaf extract 300 mg/kgBW/day (KV). Each group consisted of 5 rats and was given soursop leaf extract for 21 days after being induced by alloxan and high-fat diet. The data were analyzed using Mann-Whitney test. Results: There was a significant difference in KI group compared to KII, KIII, KIV, and KV groups. Soursop leaf extract of 150 mg/kgBW/day was the most effective dose to reduce MDA level in pancreatic rat. Conclusion: Soursop leaf extract of 150 mg/kgBW/day is the most effective dose on pancreatic MDA level reduction.

Dyslipidemia is a coronary heart disease risk factor. Dyslipidemia is characterized by the elevated levels of LDL, triglycerides, total cholesterol, and the decrease in HDL. Ginger rhizome (Curcuma xanthorriza Roxb.) and bay leaf (Eugenia polyantha Wight.) are local plants that have the abilities to decrease total cholesterol. This research design was true experimental with pre- and post-control group design. Criteria of sample were white rats, wistar strain, male, age of 8-12 weeks, and body weight range of 150-200 grams. Sampling method was simple random sampling. The experimental rats were acclimatized for seven days. Hypercholesterol diet was fed two weeks, and then the rats were given intervention and get hypercholesterol diet for two weeks. During intervention, the experimental rats were divided into 6 groups of administrationi.e, rats administered with 1) carboxymethil celluse/CMC, 2) simvastatin 0,9 mg/kg BW/day, 3) ginger rhizome extract 200 mg /kg BW/day, 4) ginger rhizome extract 400 mg/kg BW/day, 5) bay leaf extract 200 mg/kg BW/day, and 6) bay leaf extract 400 mg/kg BW/day. Blood samples were taken from caudal vein and total cholesterol levels were measured by spectrophotometry. The analysis used paired T test, One Way ANOVA test. The results showed ginger rhizome extract did not effectively reduce total cholesterol. However, bay leaf extract effectively decreased total cholesterol levels with the highest total cholesterol reduction was found in rats administered with dose of 400 mg/kg BW/day i.e, 15.4 mg/dl. Bay leaf extract have the same effectivity with simvastatin as a standard drug in lowering cholesterol level.

Abstract: Papaya leaves contain several antioxidants (flavonoid, tanin, and vitamin C) which have antiatherogenic effects that may inhibit the progression of an atherosclerotic lesion. One of the risk factors causing atherosclerosis is the consumption of food containing highly saturated fatty acids e.g. lard. Low density lipoproteins (LDL) accumulate within the intima and then are oxidized (LDL-ox). This LDL-ox is ingested by macrophages, resulting in foam-cell formation (early lesion of atherosclerosis). This study aimed to find out the histological features of the aorta of wistar rats having lard diets without the addition of the papaya leaf extract; having lard diets along with the papaya leaf extract; and having lard diets followed by papaya leaf extract. This was an experimental study on 16 wistar rats divided into 4 groups: group I without treatment (negative control group), group II lard diet for 14 days (positive control group), group III lard diet with papaya leaf extract for 14 days (treatment group I), and group IV lard diet for 14 days, and then followed by papaya leaf extract for 14 days (treatment group II). It was found that the aorta of group I showed adipose cells in the intima and media layers; group II and III showed foam cells in both layers; and group IV showed foam cells in fewer numbers than group II. Conclusion: The aorta histological features of wistar rats given lard diets for 14 days, with or without papaya leaf extract, showed foam cells in the intima and media layers. Papaya leaf extraxt added to lard diets had no effect on decreasing foam cells (no protective effect), meanwhile papaya leaf extract following lard diets showed a reduction of foam cells (therapeutic effect). Keywords: papaya leaf, lard dietary, foam cells, wistar rat.   Abstrak: Daun pepaya mengandung antioksidan (flavonoid, vitamin C) yang berefek anti-aterogenik, sehingga diharapkan dapat menghambat perkembangan lesi aterosklerosis. Salah satu faktor risiko penyebab aterosklerosis yaitu makanan yang berkandungan tinggi asam lemak jenuh, antara lain lemak babi. Konsumsi lemak jenuh berlebihan dapat mengganggu fungsi sel endotel, sehingga lipoprotein berdensitas rendah (LDL) dapat masuk dan menjadi LDL teroksidasi (LDL-oks). Makrofag menangkap LDL-oks dan menjadi sel busa (lesi dini aterosklerosis). Penelitian ini bertujuan untuk mengetahui gambaran histologik aorta tikus wistar dengan diet lemak babi tanpa pemberian ekstrak daun pepaya, diet lemak babi bersamaan pemberian ekstrak daun pepaya, dan setelah diet lemak babi dilanjutkan pemberian ekstrak daun pepaya. Penelitian ini bersifat eksperimental. Subyek penelitian terdiri dari 16 ekor tikus wistar yang dibagi menjadi empat kelompok: kelompok I tanpa perlakuan (kelompok kontrol negatif); kelompok II dengan diet lemak babi selama 14 hari (kelompok kontrol positif); kelompok III dengan diet lemak babi serta pemberian ekstrak daun pepaya selama 14 hari (kelompok perlakuan I); dan kelompok IV dengan diet lemak babi selama 14 hari, dilanjutkan pemberian ekstrak daun pepaya selama 14 hari (kelompok perlakuan II). Hasil penelitian memperlihatkan gambaran histologi aorta kelompok I tampak perlemakan; pada kelompok II terdapat sel-sel busa; pada kelompok III masih terdapat sel-sel busa; dan pada kelompok IV terdapat sel-sel busa, namun dalam jumlah yang lebih sedikit dibandingkan pada gambaran kelompok II. Simpulan: Tikus wistar dengan diet lemak babi selama 14 hari, baik dengan maupun tanpa ekstrak daun pepaya, memperlihatkan gambaran histologik adanya sel-sel busa pada tunika intima dan tunika media aorta. Pemberian ekstrak daun pepaya bersamaan dengan diet lemak babi tidak berefek menurunkan jumlah sel busa (tidak ada efek protektif) sedangkan pemberian ekstrak daun pepaya setelah diet lemak babi berefek mengurangi jumlah sel-sel busa yang terbentuk (efek terapi). Kata kunci: daun pepaya, diet lemak babi, sel-sel busa, tikus wistar.

ABSTRACTBackground: Chronic periodontitis is a periodontal disease with 80% of all cases of periodontitis. The major causes are the accumulation of plaque and bacteria. The dominant bacteria in chronic periodontitis is Porphyromonas gingivalis. Treatment of chronic periodontitis can be done by scaling and root planing and supporting therapy by using mouthwash such as Chlorhexidine gluconate 0.2% which is the gold standard in the treatment of periodontal disease. Chlorhexidine gluconate 0.2% has disadvantages so that nowadays research on herbal plants is being done to find alternative medicines that are more effective. Ramania (Bouea machropylla Griffith) leaf contains flavonoids that have antibacterial properties. Objective: To analyze the antibacterial effectivity of the flavonoid fraction of Ramania leaf extract against Porphyromonas gingivalis that causes chronic periodontitis. Method: True experimental study and post-test with control group design consisting of 5 treatment groups, namely flavonoid fraction of ramania leaf extract with concentrations of 0.1%, 0.3%, and 0.5%, chlorhexidine gluconate 0.2% as a control positive and aquadest as a negative control. Each group was repeated 6 times. Antibacterial tests using the dilution method with inhibitory rates calculated using a UV-Vis spectrophotometer and killing rates were calculated using a Colony Counter. Results: The average difference in absorbance values obtained inhibitory rates at concentrations of 0.1%, 0.3%, and 0.5%. One Way Anova Test showed a significance value of 0,000 (p < 0.05). The average number of colonies after 24 hours incubation showed the results of a kill rates in the concentration group of 0.3%, 0.5%, and positive control. The Kruskal Wallis test showed a significance value of 0,000 (p < 0.05). Conclusion: The minimum inhibitory concentration (MIC) was obtained at a concentration of 0.1% and the minimum bactericidal concentration (MBC) was obtained at 0.3% concentration.Keywords: Flavonoid Fraction, MBC, MIC, Porphyromonas Gingivalis, Ramania Leaf Extract.
