The use of mouthwash is an effective way to help cure gingivitis. Mouthwash that is often used is mouthwash containing antiseptic. Recently, there has been increasing use of traditional medicines that are considered safer such as areca nuts compared to chemically synthesized agents. The aim of this study was to calculate the difference in the healing of chronic gingivitis due to calculus between gargling using areca nut (Areca catechu) extract and using Chlorhexidine 0.2% solution. This was an experimental test with pre and post-test control group design and involved two treatment groups. A total of 30 subjects with grade 2 gingivitis were being admitted. The first group was given mouthwash with areca nut (Areca catechu) extract and another group with Chlorhexidine 0.2% twice daily for three days. The mean gingival index in the group which gargled using betel nut seed (Areca catechu) extract on the first day was 1,93±0,704 followed by 0,40±0,507 on the second day, and 0,00±0,00 on the third day, on the other hand the mean gingival index in the group which gargled using Chlorhexidine 0.2% solution was 1,93±0,704 on the first day, 0,40±0,507 on the second day, and 0,00±0,00 on the third day. The mean gingival index decreased significantly during observation period in both treatment groups but when being compared to each other there was no significant difference in the healing time of chronic gingivitis in group which gargled using betel nut seed extract (Areca catechu) and Chlorhexidine 0.2% solution.

Abstract Background: Chemical trauma to the cornea is an emergency condition of the eye that requires early diagnosis and good treatment. Alkaline have ability to saponify fatty acids in cells and cell membranes which can make penetration into the stroma and destroy proteoglycans and collagen in cells. Aloe vera (AV) contains several active substances that are reported to have anti-inflammatory, immunomodulatory, and wound healing effects. AV has been reported to accelerate the healing process of corneal epithelial defects by increasing fibroblast proliferation, collagen production and growth factor production. This study aims to determine the difference between the effect of aloe vera extract with a concentration of 10%, 20%, 40% and BSS on the healing of extensive corneal lesions in white wistar rats alkaline trauma models. Method: This study was an experimental study with a pre and posttest only with control group design in vivo approach to 30 Wistar white rats which were divided into 5 treatment groups for 3 days. Comparative analysis of effectiveness using the ANNOVA test or the Kruskal Wallis test and continued by the post hoc test. Results: Based on the one way ANOVA test there was a statistically significant difference in effectiveness between the five treatment groups on the percentage of corneal wound healing area and TGF-β expression with an assessment of p = 0,000 each. The administration of alloevera (AV) concentration of 20% had a significant difference in percentage of healing of corneal lesions and TGF-β expression compared with other treatment groups with p = 0,000 each. Large differences in the area of corneal lesions in the 40% AV group were -0.45 in the BBS group, 0.146 in the 10% AV group, 0.493 in the 20% AV group. The difference in the AV group 10% was 0.30 in the BBS group, -064 in the AV group 20%, and -0.14 in the AV group 40%. However, TGFβ expression in the normal control group that did not receive treatment was 54.94 (53.21-56-12). TGFβ levels in the BSS group were 10.44, the 10% aloe vera group was 25.43, 47.99 for the 20% aloe vera group and 37.95 for the 40% aloe vera group. Conclusion: There is a difference between the effect of aloe vera extract with concentrations of 10%, 20%, 40% and BSS on the extensive healing of corneal lesions in white wistar rats with alkaline chemical trauma models.

Introduction & Objective: Nausea and vomiting during pregnancy is one of the most common gastrointestinal disorders that more than 85% of pregnant women experience. However, controlling and treating this complication is still one of the most important issues in antenatal care. Therefore, the aim of this study was to investigate the effect of ear acupressure at Shen Men point on relieving nausea, vomiting and retching during pregnancy. Materials and Methods: In this quasi-experimental study, 100 pregnant women with a gestational age of less than 16 weeks attending the health clinics of Zabol city during 2019-2020 were studied in two control and intervention groups (n = 50 in each group). The samples in the intervention group were trained to apply pressure on their ears’ Shen Men point with the thumb for three minutes three times a day (morning, noon, and night), for a duration of one month. At the end of second and fourth weeks, the data were collected using the Rhodes index form and then, were analyzed by SPSS software version 22. Results: According to the results, there was no significant difference between the two groups in terms of age, gestational age, occupation and education. The difference in the mean scores of nausea, vomiting and retching was not statistically significant between the control and intervention groups before the study. But four weeks after the study, a significant difference was observed in the mean scores of vomiting, nausea and retching between the two groups, so that the mean scores of vomiting, nausea and retching were significantly lower in the intervention group than in the control group. Conclusion: The ear acupressure medicine at the Shen men point can be used as a non-invasive, safe and inexpensive method to relieve nausea, vomiting and retching during pregnancy.

The current study determines the effectiveness of using task-based language instructions in teaching writing at a high school in Thai Nguyen province. The participants consist of 92 grade 10 students from Bing Yen high school, Dinh Hoa district. The study employs a mix method research design (MMR) as the plan for the research. The results of the study reveals that the results of writing performance were reported at a low level (M=3.72). The results also confirmed that the intervention worked well for the experimental group. The mean score of the pre-test (the baseline for both groups) was M=3.72. The intervention focused on TBLT instructions. After first five weeks, the means of post-test1 were M=4.96 and M=3.83 for experimental group and control group respectively. There was a significant difference between the mean of pre-test and post-test1 for the experimental group (M=3.72 compared to M=4.96), while the control group showed a little improvement (M=3.72 compared to M=3.83) the difference was not significant. After another five weeks, the difference in the mean scores of the experimental group were far more than the mean scores of the control group, M=5.56 and M=4.45 respectively. By the end of the fifteenth week of the intervention, the mean of post-test 3 of the experimental group reached M=6.41, the mean for control group was M=5.54. The difference of the mean scores in the pre-test and post-test revealed a significant improvement in both groups. However, the experimental group showed a greater improvement, M=6.41 and M=5.54 respectively. It can infer that the uses of TBLT writing instruction improved writing achievement greatly.

The purpose of the present study is to investigate the effect of explicit affective strategy instruction on the speaking performance of Freshmen English majors at Faculty of Education, Suez University, Egypt. The design of the study is a pre-post quasi experimental one. The instrument is a pre/post speaking performance test (designed by the researcher). Participants were eighty Freshmen English majors, randomly divided into two groups: a control group (N=40) and an experimental one (N=40). During the experiment, the experimental group was explicitly taught some affective strategies (lowering anxiety, encouraging yourself and monitoring emotions) while the control group was taught using the traditional method. All participants were tested using the pre/post speaking performance test before and after the intervention. The difference between the post test’s mean scores of the control and experimental groups were calculated using Independent Samples t-test and the difference in the mean scores between the pre- and post tests of speaking performance was calculated for each group separately using Paired Samples t-test. A significant difference was found between the post test’s mean scores of the control and the experimental groups in favor of the experimental group. Moreover, a significant difference was found between the mean scores of the pre and post test of the experimental group in favor of the post test. It was concluded that participants’ level of speaking performance significantly improved after receiving the explicit affective strategy instruction.

Abstract Background Little information is available on the effect of ivermectin on the third and fourth stage larvae of Onchocerca volvulus . To assess a possible prophylactic effect of ivermectin on this parasite, we compared the effects of different ivermectin regimens on the acquisition of onchocercal nodules. Methods We analyzed data from a controlled randomized clinical trial of ivermectin conducted in the Mbam valley (Cameroon) between 1994 and 1998 in a cohort of onchocerciasis infected individuals. The number of nodules that appeared between the start and the end of the clinical trial was analyzed, using ANOVA and multivariable Poisson regressions, between four treatment arms: 150 µg/kg annually, 800 µg/kg annually, 150 µg/kg 3-monthly, and 800 µg/kg annually. Results The mean number of nodules that appeared during the trial was reduced by 17.7% in subjects treated 3-monthly compared to those treated annually (regardless of the dose). Poisson regression model, adjusting on subject’s age and weight, initial number of nodules and intensity of O. volvulus infection in his village of residence, confirmed that the incidence of new nodules was reduced in 3-monthly treatment arms compared to annually treatment arms, and that the dosage of ivermectin does not seem to influence this effect. Besides, the number of newly acquired nodules was positively associated with the initial number of nodules. Analysis of disappearance of nodules did not show any significant difference between the treatment groups. Conclusions Our result suggest, for the first time in humans, that ivermectin has a prophylactic effect on O. volvulus . Three-monthly treatment seems more effective than annual treatment to prevent the appearance of nodules.

Abstract Objectives During pregnancy, systemic physiological alterations lead to some changes in the oral cavity, which could prepare the mouth environment for oral and dental problems. This study was aimed to investigate salivary α-amylase, sialic acid levels, and pH levels in pregnant and nonpregnant females. Materials and Methods In this analytical, case–control study, unstimulated saliva samples were collected with spiting method from 35 pregnant women (case group) and 35 nonpregnant women (control group) and transferred to the laboratory to assess salivary α-amylase, sialic acid, and pH levels. Data were analyzed by SPSS (version: 19) software through statistical methods of independent t-test and analysis of variance. Results The mean sialic acid levels were 2.285 ± 1.230 mg/dL in pregnant and 2.744 ± 1.326 in nonpregnant women without any significant difference (p = 0.138). The mean salivary α-amylase concentrations were 2.461 ± 1.869 U/L and 2.439 ± 2.058 U/L, respectively, in pregnant and nonpregnant women, with no significant difference (p = 0.963).The mean salivary pH in nonpregnant women was significantly more than that in pregnant women (7.845 ± 0.430 and 6.868 ± 0.413, respectively) (p < 0.001). Also, the mean salivary pH levels in pregnant women were 7.474 ± 0.420 in the first trimester, 6.868 ± 0.413 in the second trimester, and 6.568 ± 0.387 in the third trimester, which were significantly different (p < 0.001). Conclusion Salivary sialic acid and α-amylase levels among pregnant women were no different from those of other subjects. During pregnancy, the salivary pH significantly reduced, and the mean salivary pH during pregnancy had a decreasing trend from the first trimester to the third trimester.

The objectives of this study are (1) to find out the students’ speaking ability before being taught by using Alvin and the Chipmunks film in spoken narrative text, (2) to find out the students’ speaking ability after being taught Alvin and the Chipmunks film in spoken narrative text, and (3) to find out whether or not there is significant difference of the students’ speaking ability before and after being taught using Alvin and the Chipmunks film at storytelling. In this study, the population was the tenth grade students of SMA Negeri 1 Gubug in the academic year 2013/2014. The number of the population was 324 students classified into 9 classes. Cluster sampling is used in taking the sample. 69 students are selected as sample out of 324 students that consist of 36 students from class Xi as the experiment group and 33 students XH as the control group. Experiment research was used here to get the data. The pre-test is given to the students on both of groups. After that, the difference treatments are given in experimental group. At the end of the research, the post-test is given to both of groups. In experiment group, the students retell the story of Alvin and the Chipmunks after watching the film and in control groups the students retell without watching the film in front of the class. The mean score of the experiment group 72.08 was higher than the mean score of the control group 65.455. The t-test application to the scores of two groups showed that the valuable (9,67) is higher than t-table (1.996). It can be seen that there is a significance difference speaking ability of the tenth grade students of SMA N 1 Gubug after being taught using Alvin and the Chipmunks film. To overcome these problems, the researcher offers some suggestions. For the school, the school should give good facilities and many media for teaching and learning process. For the teacher, the teacher should give variation teaching especially using media in spoken narrative text to improve students’ speaking skill. For the students, the students have to do more active, confident, and practice to practice speaking English

Trichuris spp. are common helminths in NHP, and benzimidazoles and avermectins have both been used to treat theseintestinal parasites. The current study compared the efficacy of fenbendazole and ivermectin against natural infection ofTrichuris spp. in African green monkeys (Chlorocebus sabaeus). Anthelmintic-naive animals (n = 65) were randomly assignedto 4 groups: an untreated control group, and 3 groups treated with either fenbendazole, ivermectin, or both compounds. Fecalsamples were collected before treatment and on days 7, 14, 28, and 60 after treatment, and fecal egg counts (FEC) were determined by using fecal flotation. The mean percentages of FEC reduction at day 60 were 100%, 86%, and 100% for treatmentwith fenbendazole, ivermectin, and both compounds, respectively. Analyzing the time series of FEC by using a Bayesian generalized linear model showed no significant difference in the proportional reduction in FEC among the 3 treatment groups, although all FEC from treated groups were significantly lower than the FEC of the control group. In contrast, the probability of shedding was highest in the ivermectin group and the lowest in the animals treated with both compounds. The probability of shedding differed significantly between the fenbendazole and ivermectin groups and between the ivermectin and combined-treatment groups. In conclusion, both fenbendazole and ivermectin are effective anthelmintics in treating Trichuris spp. infection in African green monkeys. All treatment groups showed significant reductions in FEC when compared with baseline counts and control animals; however, fenbendazole may be more effective than ivermectin when used solely or in combination with other anthelmintic treatments.
