Abstract

Propolis from Indonesia contains secondary metabolites which include flavonoids and other organic compounds. The ethanol extract of 70% propolis Trigona spp from Pandeglang can be used as an antibacterial compound. The purpose of this study was to examine the toxicity of the propolis and nanopropolis with an LC50 value, test the antioxidant activity with an IC50 value, and determine the total flavonoid content. LC50 was determined by the BSLT method on Artemia salina Leach larvae. The antioxidant activity was tested using the DPPH method (1,1 diphenyl-2-picrylhydrazil), and the determination of flavonoid content was carried out with aluminum chloride. The results showed that the LC50 value of propolis was 16.010 ppm, and for 20% nanopropolis was 18.689 ppm. Antioxidant activity obtained IC50 value for propolis is 95.54593 ppm, for 20% nanopropolis is 527.7939 ppm. The total flavonoid content of the propolis was 2.1123%, and the total flavonoid content for the nanopropolis equivalent extract was 1.5293%.

Abstract

Background: Glass ionomer cement (GIC) is a dental material often used in clinical practice. However, its use is limited due to its drawbacks. Natural resources such as propolis have been used to mainly enhance GIC’s antibacterial properties, but other properties attributed to this enhancement also require evaluation. Purpose: The study aims to evaluate the surface hardness, the surface roughness, and the water absorption of GIC containing ethanolic extract of propolis (EEP) from Trigona spp. Methods: Samples in this study were divided into four groups: GIC (control group); GIC + 25% EEP; GIC + 30% EEP; and GIC + 35% EEP. Surface roughness was measured using a surface roughness tester. Surface hardness was measured using a micro-Vickers hardness tester. Water absorption was measured by weighing the samples before and after immersion in distilled water. Surface characterization was carried out using a scanning electron microscope (SEM). Data was statistically analyzed using the Shapiro–Wilk normality test and one-way variance analysis along with the post-hoc Tukey’s test to determine significant differences between all four samples. Results: The statistical test showed significant differences in surface hardness and surface roughness between the control group and the GIC + EEP group. However, the test demonstrated no significant differences in water absorption between the control group and the GIC + EEP group. Conclusion: The addition of EEP to conventional GIC can affect its physical properties.

Abstract

Bee Pollen is a food that has a complete nutritional content including as a source of steroid hormones, helping to improve concentration and brain performance. This study aims to determine the effect of bee pollen on the sperm quality of male rats. Administering 1 ml of water as control (-), 1 ml/kg of Eurycoma longifolia capsule as control (+), 1 ml/kg of nano bee pollen, and bee pollen with concentrations of 0.33 ml/kg, 0.66 ml/kg, 1 ml/kg, and 1.33 ml/kg 34 times in Sprague Dawley male white rats. The mice were then operated on and examined for testicular weight, epididymal weight, sperm pH, sperm motility, sperm concentration, and sperm abnormalities. The results showed that bee pollen and nano bee pollen did not significantly affect the quality of rat spermatozoa. In examining the testicular weight of rats, 0.33 ml/kg of bee pollen had an average testicular weight greater than the control group. For sperm weight and pH of the rat epididymis, the administration of bee pollen showed the average weight and pH were lower than the control. In the examination of sperm motility, 0.33 ml of bee pollen had a higher percentage than the control, while 1 ml of nano bee pollen had the lowest percentage of motility. The results of the concentration and abnormalities of rat spermatozoa from a dose of 1 ml/kg of bee pollen had an average sperm count higher than the control which was 2,129.7 million/ml and the lowest percentage of sperm abnormalities was 8.73%.

Abstract

Alzheimer's Disease (AD) is one of the consequences of impaired functioning of acetylcholine which can be hydrolyzed by the enzyme acetylcholinesterase. Alzheimer's treatment is carried out using two approaches, namely compounds (acetylcholinesterase inhibitors) and noncholinergics (antioxidants). There are commercial drugs that can slow the progression of Alzheimer's, but their use can cause excessive side effects. The use of herbal plants as a cure for Alzheimer's disease has been proven to be safer and does not cause excessive side effects. Herbal plants that can be used and developed are black tea, red betel, curcuma, and cinnamon. This study determined that extracts of black tea, red betel leaf, curcuma, and cinnamon's formula have the best antioxidant activity and level of inhibition of the acetylcholinesterase enzyme. F1 (cinnamon), F5 (cinnamon, black tea, red betel, and curcuma), F6 (cinnamon and black tea), and F11 (cinnamon, black tea, and curcuma) were the best formulations in each type of sample based on inhibitory AChE enzymes and antioxidants activity. F1 (cinnamon) is the most effective extract out of all formulations analyzed in this study. Keywords: Acetylcholinesterase; Alzheimer; Black Tea; Cinnamon; Red Betel; Curcuma

Abstract

The quality of monofloral honey from Apis mellifera as an antibacterial can be influenced by the activity of the diastase enzyme and the secondary metabolites from the nectar source. Therefore, this study aimed to compare the activity of the diastase enzyme and the effectiveness of monofloral honey derived from Apis mellifera bees as a natural antibacterial agent against Staphylococcus aureus and Escherichia coli. Sampling for monofloral honey was carried out from nine different nectar sources, namely Acacia carpa, Calliandra calothyrsus, Nephelium lappaceum, Melaleuca laucadendron, Ceiba pentandra, Mangifera indica, Coffea robusta 1, Coffea robusta 2, and Hevea brasiliensisensi. Furthermore, diastase content was determined using UV-Vis spectrophotometry and the bacterial inhibition zone using the disc diffusion method. The principal component analysis (PCA) was used to analyze the clustering of diastase enzyme and antibacterial activity. The results showed that the highest diastase activity in monofloral honey was Mangifera indica, Nephelium lappaceum, and Coffea robusta 2 at 20.00 DN. This was followed by Nephelium lappaceum, Ceiba pentandra, and Hevea brasiliensisensisensi at 10.00 DN, Acacia carpa at 6.67 DN, Coffea robusta 1 at 5.00 DN, and Calliandra calothyrsus 4.00 DN. The clear zones for Staphylococcus aureus on Coffea robusta 2, Acacia carpa, Nephelium lappaceum, Coffea robusta 1, Ceiba pentandra, Hevea brasiliensisensisensi, Nephelium lappaceum, Calliandra calothyrsus, and Mangifera indica were 19.47, 18.53, 17.73, 17.03, 16.12, 16.10, 16.03, 15.73, and 14.73 mm, respectively. Additionally, the clear zones for Escherichia coli on Ceiba pentandra, Coffea robusta 2, Acacia carpa, Coffea robusta 1, Melaleuca laucadendron, Mangifera indica, Hevea brasiliensisensisensi, Calliandra calothyrsus, and Nephelium lappaceum were 27.93, 26.13, 24.60, 24.53; 24.53, 24.07, 21.90, 21.60, and 21.53 mm, respectively. In conclusion, clustering analysis was conducted based on nectar sources to evaluate antibacterial and diastase activity. The clusters identified are cluster 1 consisting of Hevea brasiliensisensi, cluster 2 including Mangifera indica, and Nephelium lappaceum. Others are cluster 3 consisting of Acacia carpa and Calliandra calothyrsus, and clustergroup 4 including Nephelium lappaceum, Ceiba pentandra, Coffea robusta 1, and Coffea robusta 2. Therefore, it was necessary to carry out antibacterial testing of other bacteria, specifically Salmonella typhi, and determine the minimum inhibitory concentration (MIC) of honey with the best antibacterial activity in various concentration variations.

Abstract

The objective of this study was to determine the effect of nanopropolis on DMBA-induced mammary tumors in rats. After the first tumor appearance, twenty-eight rats were divided into seven groups. Groups 1, 2, and 3 served as recipients of nanopropolis treatments at dosages of 8, 32, and 56 μg/mL, respectively. Group 4 received propolis at 233 μg/mL, Group 5 served as the treatment control, Group 6 received DMBA only, and Group 7 served as the normal control. The effects of nanopropolis at 32 μg/mL and propolis at 233 μg/mL were similar in reducing tumor size, healing wounds caused by the tumor, and eliminating cancer cells. Furthermore, the study suggested a relationship between particle size of the absorbent material and its effectiveness. Overall, nanopropolis was very effective in treating mammary gland tumors and breast cancer even at small concentrations.
