Bio-larvicidal Potential of Betel Leaves (Piper betle L) Ethanolic Extract in Addition of PEG 400 Diluent on Aedes aegypti Larvae
Get PDFDengue hemorrhagic fever (DHF) is a kind of vector transmitted disease, by Aedes aegypti. It is one of major public health problem around the world, including Indonesia, because it may lead to epidemics and death in a short time. The use of plant extracts as bio-larvicidal is thought to be a promising solution, and one of them is the betel leaves (Piper betle L). The addition of polyethylene glycol (PEG) as a diluent is thought may increase the dispersity of plant extract in the water which is larval medium of growth. Objectives: To determine the bio-larvicidal potential of 95% ethanolic extract of betel leaves (EEBL) in addition of PEG 400 diluent on the Aedes aegypti larval mortality. Material and Method: Betel leaves were extracted by maceration using 95% of ethanol. There are two kinds of EEBL concentration used, 0.2% dan 0.4%. PEG 400 was also added as diluent. The samples in this study were Aedes aegypti larvae at instar III-IV, with a total of 400 larvae. Evaluation was performed at 6, 12, 18, and 24 hours. The data obtained was then analyzed by Kruskall Wallis test and post-hoc Mann Whitney test. Result: In all of treatment groups, larval mortality was reached 100% at 24 hours. From the Kruskall Wallis test, p-value obtained was 0.05, and the p-value obtained in the comparation between treatment groups and negative control group was <0.05. Conclusion: EEBL in addition of PEG 400 diluent is potential as bio-larvicidal on Aedes aegypti larvae. It is also known that EEBL at concentration of 0.2% and 0.4% in addition of PEG 400 are as effective as temephos as larvicides on Aedes aegypti larvae
Comparative Cough Suppression of Chitosan Crab Extract of Uca tangeri and Dihydrocodeine
Get PDFCough is an inmate primitive reflex and acts as a part of the body's immune system to protect against foreign materials from the respiratory tract. This study was done to investigate the cough suppression potential of Uca tangeri. A day before the test, guinea pigs were placed individually in a transparent chamber (60 × 36 × 60 cm) for 5 minutes before cough was induced by exposure to 15% citric acid, delivered using an Omron compressor nebulizer (rate of 0.4 ml/minutes and particle size 5?m) for 10 minutes. The animals were then monitored visually within this exposure time for cough; the latency and counts, of which, were taken as the basal values. The animals exhibiting 10 - 20 bouts of cough were selected for the study and fasted overnight but with access to water. The selected animals were randomly allotted to 5 groups (n=5 per group). The animals were treated orally thus: Group 1 was the control group and received 2 ml/kg of normal saline; group 2 received 25 mg/kg dihydrocodeine; Group 3 received 150 mg/kg extract; group 4 received 300 mg/kg extract and group 5 received 600 mg/kg of the extract. An hour after administration, they were re-exposed to citric acid aerosol (as earlier described) and the latency of cough and cough count were recorded. The procedure was repeated at hours 2 and 3 after treatment. Antitussive activity was then evaluated in each guinea-pig as the percentage reduction in the number of coughs also known as percentage suppression of cough and percentage increase in latency of cough. The results revealed that Uca tangeri exhibited a dose dependent percentage increase in cough latency period as well as percentage increase in suppression of cough which was inferior to dihydrocodeine, but significantly greater than normal saline and basal levels
Liver Protection Effect of Red Rose Petal Methanol Extract in Copper-Induced Liver Injury in Male Wistar Rats
Get PDFThe human body requires low amounts of copper to maintain homeostasis, but high copper intake can cause various health problems. Many previous studies have been performed to look for natural products that can neutralize the excessive copper effect; one such natural product is a rose petal. Therefore, this study aims to investigate the liver protection effect of rose petals in copper-induced liver injury in male Wistar rats. This experimental study used thirty male Wistar rats that were grouped into five groups, including control, standard (quercetin), Rose Petal Methanol Extract-1 (400 mg/kg BW), 2 (800 mg/kg BW), and 3 (1,200 mg/kg BW). All groups were treated for 14 days, and all rats were given copper (II) sulfate suspension for the last three days. On the fifteenth day, all rats were sacrificed to obtain blood and liver tissue SGOT, SGPT, and liver histology study. The results showed that rose petal methanol extract significantly decreased SGOT and SGPT levels compared to the control group (P-value <0.05). The reduced area of ballooning degeneration and necrosis were in line with the increased dose of rose petal extract supported the liver protection effect of rose petal extract. Therefore, it can be concluded that rose petal methanol extract protects the liver against copper impacts
Synthesis, Spectroscopic Analysis and Antidiabetic Properties of Copper (II) Complex of Mangifera indica Leaf Crude Extract
Get PDFMany applied conventional drugs in treating diabetes have been reported to possess some drawbacks which necessitate a search for alternative therapies. In order to search for a more active antidiabetic agent, this study synthesized and evaluated antidiabetic properties of Mangifera indica crude extract and its Cu (II) complex in alloxan-induced diabetic albino rats. The leaf crude extract and its metal complex were characterized using percentage metal analysis and IR spectroscopic data. Experimental animals were induced by a single intraperitoneal injection of Alloxan monohydrate at a single dose of 140 mg/kg body weight and animals with fasting blood glucose level (BGL) > 200 mg/dL were considered diabetic. Metformin was used as a standard drug. Fasting blood glucose level and body weight were used to assess the antidiabetic activity. One-way ANOVA was used to determine the level of statistically significant at p< 0.05. The crude extract was found to coordinate with the metal ion through O donor atom of C=O and O-H of phenol and ketone respectively. The Cu (II) complex of the crude extracts at tested dose of 600mg/kg demonstrated more antidiabetic activity without weight gain than the standard drug. It is concluded that the Cu (II) complex could be a potential material in the development of more active and negative-side-effect-free antidiabetic drug
Nanotechnology-Based Vaccines
Get PDFSeveral new infectious diseases have developed in recent years, and a few old ones that were formerly thought to pose no threat to humans have made a comeback. Millions of fatalities are attributed to these illnesses together, having a significant negative influence on the worldwide socioeconomic and healthcare sectors. The lack of appropriate medications for many of these disorders is one of the biggest obstacles to treating them. Yet, several of the most common diseases currently have no vaccinations that are reliable. The ideal vaccine should have several key characteristics, including safety, stability, and the capacity to induce a sufficient and long-lasting immune response with a minimal number of doses. To induce protective immunity against illnesses, different generation vaccines are employed, including attenuated or dead entire organisms (first generation), subunits (second generation), and RNA or DNA vaccines (third generation). To get beyond these obstacles, a reliable vaccination delivery mechanism is needed, one that not only gets the vaccine molecules to the target region where they can trigger long-lasting immune responses but also has few side effects and uses fewer doses. Only a few hundred atoms make up the majority of nanoparticles. Nanoparticles have a relatively significant surface area-to-volume ratio because of their extremely small size. Nanoparticles can have surprising optical, physical, and chemical properties due to this property. Nanotechnology has many benefits for the creation of vaccines for the next generation. A delivery strategy based on nanocarriers can shield vaccines from early deterioration, increase stability, have high adjuvant qualities, and can help with the targeted distribution of an immunogen. The researcher conducts an examination of articles that are in accordance with the issue to be studied. Articles used in the literature review are obtained through the database of international journal providers through PubMed, we investigated clinical studies and discussed what happened in these clinical studies and the extent of the effectiveness of Nanoparticle-Based Vaccines. In order to achieve effective vaccine distribution and generate the required host immunity against infectious diseases, this review article focuses on the applications of nanocarrier-based vaccine formulations and the methodologies utilized for functionalizing nanoparticles
