The Porphyromonasgingivalis is one of the dominant bacteria that causes chronic periodontitis. These bacteria can penetrate the gingiva and cause tissue damage directly or indirectly with the induction of inflammation. The growth of Porphyromonasgingivalis can be inhibited by administrating the active compounds from plants that have an antibacterial effect such as Calotropisgigantea leaves.This study aimed to determine the antibacterial potential of Bidurileaves (Calotropisgigantea) extract against the Porphyromonasgingivalis ATCC. In this study the Biduri leaves were extracted by maceration method using 70% ethanol solvent. The antibacterial potential test of 70% ethanol extract of Biduri leaves (with a concentration of 5%, 10%, 15%, 20%, 25%, 30%, and 35%) against thePorphyromonasgingivalis was carried out using dilution method with 4 times repetition on Tryptone Soy Agar (TSA) media.The results of the study were analyzed using the One Way ANOVA test showing there were significant differences in the number of Porphyromonasgingivalis ATCC 33277 colonies due to administration of 70% ethanol extract of Bidurileaves (Calotropisgigantea) with p values <0,05. The test results were continued with the Post Hoc Tamhane test to determine the significant difference of the treatment groups. Based on the results of the study it could be concluded that 70% ethanol extract of Biduri leaves (Calotropisgigantea) had antibacterial potential against Porphyromonasgingivalis ATCC 33277 starting from the smallest concentration of 5% to the highest concentration of 35%.

Phaleria macrocarpa (Scheff.) Boerl. has been widely used in the treatment of diabetes mellitus but its effectiveness is still inconclusive so it needs to be compared with standard drugs such as metformin. This study aims to analyze the effects of P. macrocarpa fruit extracts on blood sugar levels and the repairing of the pancreatic Langerhans islets of diabetic rat models. The study was conducted experimentally by pre and post-test design with a control group. Thirty white rats were divided into 6 groups. All rats were treated with 40 mg/200 g BW of streptozotocin (STZ) to induce hyperglycemia, except group I. Group II as a negative control was given with aquadest. Group III, IV, and V were given with ethanol extract of P. macrocarpa pericarps at doses of 200, 250, and 300 mg/200 g BW/day, respectively. Group VI was given with metformin at a dose of 150 mg/200 g BW/day. On the 22nd day of treatment, blood specimens were taken for examination of fasting blood sugar levels and pancreatic organs were analyzed for histopathological examination of the islets of pancreatic Langerhans. The data were statistically analyzed with α<0.05; CI95%. Paired sample t-test results showed a significant decrease in blood sugar levels before and after treatment in group V (p-value=0.048). One way anova and post hoc Least Significant Difference (LSD) test results showed a significant difference in mean blood sugar levels after the final treatment between groups I and II (p-value=0.013), I and III (p-value=0.004), I and IV (p-value=0.002), I and VI (p-value=0.000), II and VI (p-value=0.031), and V with VI (p-value=0.005); one way anova and post hoc LSD test results showed a significant difference in the mean area of islets of pancreatic Langerhans between group I and all treatment groups (p-value=0.000), II with V and VI (p-value=0.000 and 0.009), III with V and VI (p-value=0.000 and 0.001), and IV with V (p-value=0.003). It can be concluded that the extract of P. macrocarpa pericarps showed a hypoglycemic effect and repaired the damage in Langerhans islets of STZ-induced rat in a dose-dependent manner.

OBJECTIVEThe Barrow Ruptured Aneurysm Trial (BRAT) is a prospective, randomized trial in which treatment with clipping was compared to treatment with coil embolization. Patients were randomized to treatment on presentation with any nontraumatic subarachnoid hemorrhage (SAH). Because all other randomized trials comparing these 2 types of treatments have been limited to saccular aneurysms, the authors analyzed the current BRAT data for this subgroup of lesions.METHODSThe primary BRAT analysis included all sources of SAH: nonaneurysmal lesions; saccular, blister, fusiform, and dissecting aneurysms; and SAHs from an aneurysm associated with either an arteriovenous malformation or a fistula. In this post hoc review, the outcomes for the subgroup of patients with saccular aneurysms were further analyzed by type of treatment. The extent of aneurysm obliteration was adjudicated by an independent neuroradiologist not involved in treatment.RESULTSOf the 471 patients enrolled in the BRAT, 362 (77%) had an SAH from a saccular aneurysm. Patients with saccular aneurysms were assigned equally to the clipping and the coiling cohorts (181 each). In each cohort, 3 patients died before treatment and 178 were treated. Of the 178 clip-assigned patients with saccular aneurysms, 1 (1%) was crossed over to coiling, and 64 (36%) of the 178 coil-assigned patients were crossed over to clipping. There was no statistically significant difference in poor outcome (modified Rankin Scale score > 2) between these 2 treatment arms at any recorded time point during 6 years of follow-up. After the initial hospitalization, 1 of 241 (0.4%) clipped saccular aneurysms and 21 of 115 (18%) coiled saccular aneurysms required retreatment (p < 0.001). At the 6-year follow-up, 95% (95/100) of the clipped aneurysms were completely obliterated, compared with 40% (16/40) of the coiled aneurysms (p < 0.001). There was no difference in morbidity between the 2 treatment groups (p = 0.10).CONCLUSIONSIn the subgroup of patients with saccular aneurysms enrolled in the BRAT, there was no significant difference between modified Rankin Scale outcomes at any follow-up time in patients with saccular aneurysms assigned to clipping compared with those assigned to coiling (intent-to-treat analysis). At the 6-year follow-up evaluation, rates of retreatment and complete aneurysm obliteration significantly favored patients who underwent clipping compared with those who underwent coiling.Clinical trial registration no.: NCT01593267 (clinicaltrials.gov)

Kersen leaf (Muntingia calabura L.) contains tannins, flavonoids and polyphenol compounds allegedly have analgesic effect. The objective was to determine the analgesic effect of ethanol extract of kersen leaves and to determine the most effective analgesic dose. This study was an experimental research. Leaves were extracted with ethanol 70% and the analgesic effect test was divided into 5 groups: negative control treatment (distilled water), positive control (mefenamic acid 2.6mg/kg), kersen leaf ethanol extract first dose (100mg/kg), second dose (200mg/kg) and tthird dose (400mg/kg). Giving treatments by oral, after 30 minutes, the mices were given a pain inductor with 0.5% acetic acid by intra peritonial administration. Analgesic power was calculated by counting the number of writhing in mice for 1 hour. The results showed that the ethanol extract of cherry leaf has analgesic effect. From the calculation of the first dose analgesic power (42.9%), second dose (59.4%) and the third dose 69.9%. Statistical test results kruskal wallis value of p=0.011 (p<0.05) showed a significant difference between all analgesic treatment groups. The conclusion of this study is all of the ethanol extract had analgesic effects on male white mice, whereas a dose of 400mg/kg is the most effective analgesic dose.

INTRODUCTION: By examining the relationship between changes in maximum mild-expiratory flow( MMEF) and specific airway conductance(sGaw), parameters with the change in FEV1 when evaluating the spirometer test and the bronchodilator response, we investigated their diagnostic contribution to the bronchodilator response in those with partial responses to FEV1. METHODS: The retrospective study sample consists of data from 112 patients between Jun 1, 2019, and Feb 1, 2020 who applied to the pulmonary function laboratory with a pre-diagnosis of bronchial hyperreactivity as well as body plethysmography test performed together with the reversibility test. RESULTS: MMEF% and ▲sGaw were linearly correlated with ▲FEV1 (respectively r = 0.752; p <0.001, r = 0.611; p <0.001). While there was a significant difference between ▲MMEF% and ▲sGaw between reversible, partially reversible, and irreversible groups (P <0.001), there was no significant difference in ▲sGaw between partial reversible and reversible groups in post-hoc comparisons (P> 0.05). In the binary logistic regression model created between the partially reversible and reversible groups, demographic characteristics, MMEF% and ▲sGaw variables, ▲MMEF was an independent predictor [OR: 1.132; 95% CI (1.036-1.238), p = 0.006]. The 24% threshold for absolute reversibility or partial reversibility calculated with MMEF% was significant, indicating significance at 86.2% sensitivity and 80.8% specificity (AUC: 0.811, 95% CI: 0.686-0.936; p <0.001). This value we found defined 81% of the partially reversible group as reversible. DISCUSSION AND CONCLUSION: We observed that ▲sGaw alone didn' have a determinant contribution for determining reversibility in bronchodilator response, which showed partial reversibility with respect to FEV1 change. We believe that ▲MMEF% can be an independent predictor between these two groups and the calculated threshold value of 24% can be used as a criterion for determining the reversibility in cases where FEV1 is not determinant.

Contaminated water often affects the occurrence of periodontitis in the coastal area. The diabetic hypercholesterolemia-induced periodontitis in Indonesia is very high. The use of coenzyme Q10 to treat this disease has never been investigated yet. Therefore, this study aimedto analyze the effect of coenzyme Q10 on the lipid profile of diabetic hypercholesterolemia-induced periodontitis.Twenty four rats were randomized into 6 groups (G1-G6). The groups (G1-G3) are healthy, negative and positive control group respectively. The treatment groups (G4-G6) are diabetic hypercholesterolemia-induced rats given coenzyme q10 dose of 13,5; 27 and 54 mg/kg respectively. Rats were induced by periodontitis, hypercholesterolemia and diabetes mellitus. Coenzyme Q10 was administered orally using 2 mL gastric tube once a day for 14 days. Lipid profile including triglycerides, HDL, and atherogenic index (IA) was measured enzymatically by the CHOD-PAP method. Data were analyzed by one-way ANOVA test and followed by the Least Significant Difference (LSD) post hoc test.Coenzyme Q10 with a dose of 54 mg/kgis effective in lowering triglyceride, and atherogenic index and increasing HDL level in diabetic hyperlipidemia-induced periodontitis rats model. This research supports the potential effects of coenzyme Q10 supplementation to improve lipid profile in diabetic hypercholesterolemia-induced periodontitis in the coastal area.

Objectives The aim of the study was to evaluate the appetite-stimulating effect of gabapentin by comparing it with mirtazapine in healthy cats in the first 8 h after ovariectomy surgery. Methods This double-masked, placebo-controlled, prospective clinical trial included 60 healthy cats presented to the hospital for ovariectomy: 20 received gabapentin, 21 received mirtazapine and 19 received a placebo immediately before and 6 h after surgery. Food was offered at 2, 4, 6 and 8 h post-ovariectomy. After each meal, food intake was measured. Data were analysed using repeated-measure ANOVA and a linear mixed-model analysis. Post-hoc Tukey’s honest significant difference test was performed for multiple comparisons. Results Food intake increased in both treatment groups vs placebo. No statistically significant difference was found between cats treated with gabapentin or mirtazapine. Conclusions and relevance Cats receiving gabapentin ate more than cats in the placebo group. Thirty percent of cats in the gabapentin group covered their resting energy requirements, while none of the cats in the placebo group did. Gabapentin and mirtazapine produced similar effects on food intake.
