The Effect of Tiwari Onion (Eleutherine americana Merr) Tablet on Blood Pressure Stability in Diagnosed Hypertension Patients

BACKGROUND: Non-pharmacological management is carried out by adjusting the lifestyle and non-pharmacological therapy for hypertension sufferers. They use herbal therapy, which is believed to have low side effects, easy, and inexpensive, such as Eleutherine americana Merr Tea. AIM: This study aimed to analyze Effect of E. americana Merr Tablet on blood pressure in hypertensive patients to be used as supportive therapy to reduce and stabilize blood pressure. METHODS: This study used a quasi-experimental research design pre-post-test with a control group design, involving 30 respondents. Data collection was carried out for 1 month. Then blood pressure observations were carried out every 1 week for a month after giving E. americana tablets. The sampling technique was purposive sampling method. The data analysis used was the Independent Sample T-Test with a significance level of p < 0.05. RESULTS: The majority of respondents according to age were in the final elderly age range; 15 people (50%) were 56–65 years old. Most of the respondents involved were female, about 18 people (60%). The respondents’ hypertension category included hypertension Grade 1 (57%) and hypertension Grade II (43%). The independent sample t-test obtained p = systole was 0.029 and diastole was 0.000 (p < 0.005). It showed a significant difference in blood pressure before and after being given E. americana tablets in hypertensive patients. CONCLUSION: Significant decrease in systolic and diastolic blood pressure in patients with suspected hypertension who obtained E. americana tablets.

Combination of Bawang Dayak Extract and Acarbose against Male White Rat Glucose Levels

Diabetes is a chronic metabolic disease with signs of increased blood glucose levels. Type 2 diabetes is common diabetes in adults. Bawang dayak is one of the plants believed to have the efficacy of curing various types of diseases. The purpose of this study was to find out the comparison of hypoglycemic effects between combinations of bawang dayak extract and acarbose with single acarbose. This study was an experimental study using 32 white mice divided into two groups. Group one was given a combination of bawang dayak at a dose of 100 mg/kg BW and acarbose at a dose of 40 mg/100 g BW, while group two was given acarbose at a dose of 40 mg/100 g BW. Treatment is administered after the test animal is induced with dexamethasone at a 1 mg/kg BW dose dissolved in NaCl 0.9% subcutaneously for 12 days. Measurement of glucose levels was carried out using a glucometer. Data retrieval was carried out every three days for 15 days after previously fulfilled for +10 hours. Blood glucose level data were analyzed with the General Linear Model test. The combination of bawang dayak-acarbose onion extract had a greater decrease in blood glucose levels than single acarbose. Average reduction in blood glucose levels for D+3; D+6; D+9; D+12; and D+15 was 187.31; 168.56; 140.81; 119.81; and 102.56 mg/dl, respectively. The General Linear Model test results showed a p <0.05 value that significantly impacted blood glucose levels between groups.

Pengaruh Pemberian Ekstrak Etanol Umbi Bawang Dayak (Eleutherine palmifolia (L.) Merr.) Secara Oral pada Mencit BALB/c Terhadap Pencegahan Penurunan Diameter Germinal Center pada Kelenjar Getah Bening Serta Kadar IgG Serum

ABSTRAKSalah satu tanaman yang memiliki kandungan imunostimulator yaitu bawang dayak (Eleutherine palmifolia (L.) Merr.). Ekstrak etanol umbi bawang dayak (EEUBD) memiliki kandungan fitokimia yang bersifat sebagai antioksidan antara lain triterpenoid, flavonoid, fenolik, alkaloid dan tanin. Flavonol berpotensi sebagai imunostimulan meningkatkan produksi IL-2 yang terlibat dalam aktivasi dan proliferasi sel T. Flavonoid dapat menginduksi Th1 untuk menghasilkan IFN- γ, IFN- γ berperan untuk menginduksi sel limfosit B memproduksi imunoglobulin. Untuk mengetahui potensi pengaruh pemberian ekstrak etanol umbi bawang dayak dalam pencegahan penurunan diameter germinal center pada kelenjar getah bening serta pencegahan penurunan kadar Ig G serum pada mencit yang diinduksi metilprednisolon oral dilakukan penelitian dengan desain eksperimental. Pada penelitian ini mencit dikelompokkan menjadi lima kelompok yaitu kelompok I (K1) merupakan perlakuan kontrol hanya diberi CMC Na+ 0,5 %. Kelompok II (K2) merupakan model imunosupresi yaitu kelompok perlakuan yang diinduksi metilprednisolon 0,08 mg/30 grBB mencit/ hari terlarut dalam 0,2 ml aquades. Kelompok III (K3) dengan perlakuan metilprednisolon ditambah EEUBD dengan dosis 50 mg/kgBB. Kelompok IV (K4) dengan perlakuan metilprednisolon ditambah EEUBD dengan dosis 100 mg/kgBB dan kelompok V (K5) dengan perlakuan metilprednisolon ditambah EEUBD dengan dosis 200 mg/kgBB, diberikan sekali sehari selama 14 hari bersamaan pemberian induksi metilprednisolon pada sore hari secara per-oral (sonde intragastrik). Kemudian diamati peningkatan diameter germinal center dan kadar Ig G serum. Data hasil penelitian antar kelompok dianalisis dengan menggunakan uji korelasi bivariat koefisien pearson. Hasil penelitian menunjukkan bahwa EEUBD terbukti sebagai imunostimulator terhadap peningkatan diameter germinal center pada dosis 100 mg/kgBB dan peningkatan kadar Ig G serum pada dosis 200 mg/kgBB.Kata-kata kunci : bawang dayak (Eleutherine palmifolia (L.)
