Background: Gonorrhea cases experiencing antibiotic resistance are increasing due to inadequate treatment or failure to contribute to an increase in antibiotic resistance cases; WHO suggests adding herbal therapy treatment methods is expected to minimize the occurrence of drug resistance as much as possible. Previous studies that have been carried out using other herbal plants have not shown any potential to inhibit the growth of Neisseria gonorrhoeae bacteria, seen from the amount of extract concentration and the dosage and content of the compounds in the contents monitoring the time.Objective: To analyze the difference in the effect of various concentrations of Matoa Leafs Extract (Pometia Pinnata) compared to 500mg Levofloxacin on the increase in the growth inhibition of Neisseria gonorrhoeae.Methods: This is true-experimental research with a post-test-only control group with a randomized design. The sample in this study was the microorganism Neisseria gonorrhoeae obtained through vaginal swabs in 2 females (FSW) positive for Gonorrhea by gram staining and microscopic examination and culture on Chocolate Agar Plant (CAP) media. The culture was then suspended in CAP media. Matoa Leaf extract concentration of 100%, 80%, 60%, 40%, 20%, positive control with Levofloxacin 500 mg and negative control with distilled water with four replications and monitoring in 24 hours, 48 hours, 72 hours, and 96 hours. Data analysis used Kruskal-Wallis, Mann-Whitney, and cohen's test. Result: Levofloxacin 500mg in inhibiting Neisseria Gonorrhoeae bacteria is very effective, and Matoa Leaf extracts 60% and 40% P=0,026 have a strong enough potential to inhibit the growth of Neisseria gonorrhoeae bacteria with the same potential strength. The cohen's test 1.4 effect the levofloxacin 500mg provides a significant influence inhibiting Neisseria Gonorrhoeae.Conclusion: Matoa Leaf extract 60%, and 40% have solid antibacterial potential, although not as strong as Levofloxacin 500mg.

Aim:: The present work was aimed to find out the anti-allergic activity of ethanol extracts of Quisqualis indica Linn. (EEQI) by in-vitro and in-vivo murine models. Background:: Worldwide, the rise in prevalence of allergic diseases has continued in the industrialized world for more than 50 years. Worldwide, 0.05–2% of the population is estimated to experience anaphylaxis at some point in life. Quisqualis Indica Linn in an ornamental plant that have been rarely used as a herbal medicines, however presence of polyphenols and flavonoids have been reported to possessed anti-inflammatory, antipyretic and immunomodulatory activity which have some pathological relevance with anaphylaxis. Objective:: The objective of the present research was to investigate, scientifically explored and understand the probable antianaphylactic mechanism of ethanol extracts of Quisqualis indica Linn. via different preclinical models. Material and Method:: In-vitro study was done on de-granulated mesenteric mast cells induced by compound 48/80 and invivo study was done by passive cutaneous anaphylaxis (PCA) model. In the in-vitro study degranulated mesenteric cells were grouped into negative control (compound 48/80 treated), positive control (Disodium cromoglycate + 48/80 treated) and 3 test groups (EEQI 10 μg/ml + 48/80 treated, EEQI 50 μg/ml + 48/80 treated and EEQI 100 μg/ml + 48/80 treated). The number of degranulated mast cells was counted and compared within the different treatment groups. In the in-vivo study the rats were first grouped into negative control (vehicle only), positive control (Disodium cromoglycate) and 2 test groups (EEQI: 100 and 200 mg/kilogram). The animals were pretreated for 12 days. On the 12th day all the rats were immunized with serum anti-ovalbumin (obtained from an already sensitized rat) by the intradermal route. After 24 h of serum injection, Evans blue dye containing oval albumin was administered intravenously in all groups. Three days later, the rats were taken down for the severity of the anaphylactic reactions. Result:: EEQI significantly attenuate mast cell degranulation and maintain the cell intactness as compared to control (P < 0.001). It was set up to support the degree of anaphylaxis as compared to control group (P < 0.001). Conclusion:: The outcomes of the work revealed the preventive effect of Quisqualis indica Linn. against allergic manifestations.

Abstract Objective: To test the null hypothesis that the silver soldering employed in orthodontics is not cytotoxic for fibroblasts. Materials and Methods: This in vitro study was performed using a culture of mice fibroblasts (lineage NIH/3T3), divided into four groups (n = 10 each): control, negative control (stainless steel archwire), positive control (amalgam disks), and test group (silver soldering). After cell culture in complete Dulbecco modified eagle medium and achievement of confluence in 80%, the suspension was added to the plates of 24 wells containing the specimens and incubated in an oven at 37°C for 24 hours. The plates were analyzed on an inverted light microscope, photomicrographs were obtained, and the results were recorded as response rates based on modifications of the parameters of Stanford according to the size of the diffusion halo of the toxic substance and quantity of cell lysis. Results: The results revealed a maximum response rate for the silver soldering group, as well as severe inhibition of cell proliferation and growth, more round cells with mostly darkened and granular aspects, suggesting lysis with cell death. A similar response was seen in the positive control group. Conclusion: The hypothesis is rejected. The silver soldering used in orthodontics represents a highly cytotoxic material for the cells analyzed.

Background: The process of wound healing is influenced by various factors such as age, hormones, and wound care. Wound care is done to accelerate wound healing which can be done by various methods, one of them is traditional care. Traditional wound care can use medicinal plants. Rhodomyrtus tomentosa is a medicinal plant that has an antioxidant, anti-inflammatory, antitumor and antibacterial content. Thus this study aims to evaluate the effectiveness of the antiseptic solution of the Rodhomyrtus tomentosa leaf extract on wound healing in male Wistar rats. Method: this research is pure experimental research with post test only control group design. Thirty male white rats were divided into five groups, namely negative control, positive control, Rhodomyrtus tomentosa leaf extract 15%, 30%, and 60%. Rhodomyrtus tomentosa leaf extraction was carried out by maceration method with 70% ethano solvent. The extraction results are divided into 3 concentrations (15%, 30% and 60%). The wound healing process was evaluated by measuring the length of the wound manually from 0 to 10 days in each group. Meanwhile, the number of fibroblast cells was calculated through hematoxylin eosin (HE) staining and observed using an Olympus CX41 microscope with a 10x magnification and objective lens magnification in 3 fields. Result: There was a significant difference in the reduction in wound length (p =< 0,000) between the five experimental groups (Rhodomyrtus tomentosa leaf extract solution 15%, 30% and 60%, negative control and positive control. Solution of rhodomyrtus tomentosa leaf extract accelerated the increase in the number of fibroblasts compared to the negative control group (p = 0.003), but did not make a difference (p = 0.403) with the positive control group. Rhodomyrtus tomentosa leaf extraction solution had the same microscopic effect on the number of fibroblasts with a positive control group given 0.9% NaCl solution. Conclusion: There was a significant difference in the number of fibroblasts between all groups, but no difference in wound healing length.

<p class="Abstract">In this study the antidiarrheal activity of ethanolic extracts of the leaves of <em>Mikania cordata</em> and <em>Litsea monopetala</em> was evaluated. Diarrhea was induced in mice by oral administration of castor oil (0.5 mL) 30 min after the administration of the extracts. During a 4 hour study the number of diarrheal feces and percentage inhibition of the extracts (200 and 400 mg/kg body weight) was determined. Loperamide (3 mg/kg body weight) served as standard and belonged to the positive control group. The extracts exhibited potent antidiarrheal activity as well as achieved statistically significant p value (p&lt;0.01 and p&lt;0.05) compared to control group. Among the extracts the highest percentage inhibition of defecation (60%) was recorded for leaf extract (400 mg/kg body weight) of <em>L. monopetala</em>. So, the study corroborates the significant antidiarrheal activity of <em>M. cordata</em> and <em>L. monopetala</em> leaf extracts and raises the demand of further sophisticated investigation.</p><p> </p>

Tooth extraction is a process of removing teeth from the alveolar bone. In wound healing, fibroblast are very important cells. The main purpose of this study was to determine the effect of mobe leaf 1% and 3% extract gel (Artocarpus lakoocha) on fibroblast proliferation in post extraction tooth socket wound healing. This research used 16 samples of wistar rats, divided into 4 groups, a positive control group, a negative control group and a 1% and 3% mobe leaf extract gel group. The left mandibular incisors were extracted, then 1% and 3% gels of mobe leaf extract were applied on day 1 to day 7. Data analysis was calculated using the Kruskal-Wallis test on clinical data and one way ANOVA test for microscopic. The result of the socket wound healing activity test for a good concentration of mobe leaf extract gel was 3%. This research shows significant resultith p-value of 0.018 (< 0.05) on the closure of the socket wound clinically which means the closure of the wound accelerates because of the mobe leaf 3% extract gel treatment. The distance of fibroblast on microscopically shows significant resultith a p-value of 0.002 (< 0.05), which means that there was an enlargement of the distance fibroblast at the socket wound closure with application of mobe leaf 3% extract gel. From the results of the study it can be concluded that mobe leaf 3% extract gel has the best ability to show acceleration the closure of the socket wound either clinically or microscopically.
