This study determined the effect of Mango mistletoe Methanolic Extract (MMME) on the cardiac's histopathological profile of hypertensive rats (DOCA-Salt) treated. The MMME was treated on fifty rats for 14 days, divided into five treatments: negative control, positive control, doses 50, 100, and 200 mg/kg BW with five replications. One-way ANOVA analysis was used, namely JAMOVI with version 1.1.9.0, and for cell calculation, diameter using the IMAGE J application. Results showed that there were no significant differences in the histopathological profile of the cardiac in hypertensive rats (DOCA-Salt) treated with MMME for 14 days on the diameter of the heart muscle cells between the control (+) and control groups (-), treatments 1, 2, and 3. This is evidenced by the analysis of p-value> 0.05, namely 0.187 millimeters. Therefore, we concluded that MMME does not affect the diameter of heart/cardiac organ muscle cells. However, there was a significant difference in the amount of necrosis in the cardiac of hypertensive rats between control (+) and control (-) groups, treatments 1, 2, and 3. Based on the results, MMME reduces the number of necrosis in the heart/cardiac organ.

Abstract Shallot is a horticulture crop with a fibrous root system, which is susceptible to water deficit, particularly in the bulb formation stage. This study was carried out to examine the effects of salicylic acid (SA) and biosilica (Si) exogenous induction on plant growth of shallot grown under water deficit in plastic baskets. A factorial 4×2 experiment was laid out in a randomized complete block design with four blocks. The first factor of treatments was a four-level exogenous induction, i.e., 0.5mM SA, 6mM Si, combination (0.5mM SA and 6mM Si), and control (0 without SA and Si). The second factor was a level of interval irrigations i.e, one-day interval and three-day interval. The results showed that the treatment of combination 0.5mM SA and 6mM Si can maintained a plant height and the number of leaves was better than the control under water deficit. Avoidance was one of the mechanisms of shallot in dealing with water deficit, namely by reducing the stomatal density. Decreased stomatal density was negatively correlated with water use efficiency.

Ascariasis is an intestinal infection caused by the parasitic worm Ascaris lumbricoides. Starfruit leaf (Averrhoa bilimbi) and leaf anting-anting (Acalypha indica L) is a plant that is often used as a worm remedy in the community. Starfruit leaves (Averrhoa bilimbi) and Leaf anting-anting (Acalypha indica L) contain several compounds that have the potential as anthelmintics, namely saponins, tannins and flavonoids. The purpose of this study was to determine the effect of ethanol extention of starfruit leaf leaves (Averrhoa bilimbi) and leaf anting-anting (Acalypha indica L) as anthelmintic on the time of death of Ascaris suum Goeze worms in vitro. The method in this study is experimental with post test only group design. Test animals from the study are Ascaris suum. The study was conducted at the Parasitology Laboratory, Medical Laboratory Department, Poltekkes Kemenkes Surabaya in 2019. This study used 6 treatment groups, NaCl 0.9% as a negative control and pirantel pamoate 0.25% as a positive control and ethanol extract of wuluh starfruit leaf and ethanol extract of Anting-anting with concentrations of leaves. 40%, 60%, 80% and 100%. Data were analyzed using the Kolmogrov-Smirnov test, the Anova two way Block Design test, then continued using the Post Hoc test to determine differences between blocks and between treatments, against the time of Ascaris suum worm's death. The average time of death of Ascaris suum caused by ethanol extract of starfruit leaves concentration of 40% for 492.3 minutes and ethanol extract of leaf anting-anting 396.5 minutes, concentration of 60% ethanol extract of wuluh starfruit leaves for 278.5 minutes and leaf extract ethanol leaf anting-anting for 283.5 minutes, 80% concentration of ethanol extract of wuluh starfruit leaf for 141.8 minutes and ethanol extract of anting-anting leaf for 174 minutes, 100% concentration of ethanol extract of wuluh starfruit leaves for 66.75 minutes and extract ethanol leaf anting-anting for 92 minutes. So it can be concluded that the ethanol extract of starfruit leaves has an anthelmintic effect on the Ascaris suum worm more optimum than the ethanol extract of the Anting-anting leaves, because the time required is close to positive control that is 60 minutes.

This study aimed to test the effects of dietary Aloe vera and Symphytum officinale extracts added separately or in combination with symbiotics on the performance, nutrient utilization, serum biochemical parameters, biometrics, and intestinal histomorfometry of broilers. The experiment had a randomized block design with five treatments and six replicates of ten broilers each. Treatments were as follows: negative control and positive control (diet without and with antibiotic, respectively); 0.2% Aloe vera (AV); 0.2% Symphytum officinale (S); 0.2% functional supplement, composed of symbiotics fermented in Aloe vera and comfrey plant extracts (S+PE). At seven days of age, FI of birds fed the Aloe vera extracts diets were lower than that observed for birds consuming the diet with Symphytum officinale extract and S+PE. Broiler performance remained unaffected by treatments at others ages evaluated. At 10 to 14 days of age the lowest ADCDM ADCCP was shown in group feed NC. The highest ADCCP was observed in PC control group and in diets supplemented with Aloe vera and S+PE. Serum levels of cholesterol, triglycerides, and phosphorus were affected by addition of extracts at seven, 21, and 35 days of age. The longest duodenal villi were observed in broilers fed S+PE diets at seven days of age. Aloe vera and Symphytum officinale extracts and symbiotics can be used in broiler diets as an alternative to growth-promoting antibiotics.

ABSTRACTInduced resistance to bacterial leaf blight disease in rice field by indigenous rhizobacteria.  Bacterial leaf blight is the most important disease on paddy at Southeast Sulawesi. Utilization of biological agents that induce plant resistance is an alternative tool to control bacterial leaf blight disease on paddy. The aim of  the experiment was obtain rhizobacteria that were able to stimulate the growth of paddy plants as well induce plant resistance towards bacterial leaf blight in the field. All experiment units were arranged with a factorial design in a randomized complete block design. The first factor was the rhizobacteria isolates, consisting 4 treatments, i.e: without rhizobacteria (R0), isolate P11a (R1), isolate PKLK5 (IR2), and  mixture P11a and PKLK5 (R3), the second factor is paddy varieties, (V1): IR64 variety, (V2): Cisantana variety. The pathogen was inoculated on leaf when 45 day after crop.  Weekly observation of disease severity, vegetative plant growth (leaf and stem numbers), and yield were conducted. The results showed that the 10 isolates of rhizobacteria tested were able to induce plant resistance toward bacterial leaf blight, stimulated vegetative growth as well as increased yield of paddy plant. Rhizobacteria application could increase the resistance of paddy toward Xanthomonas oryzae pv. oryzae. The application rhizobacteria could increase the vegetative plant growth, application  mixture P11a and PKLK5 isolates showed higher resistance than single application in terms of plant growth and yield, both IR64 and Cisantana varietes

Abstract The objective of this present study was to determine the effects of phytase dosing on growth performance, mineral digestibility, phytate breakdown, and the level of glucose transporter type 4 (GLUT4) in muscle plasma membranes of weanling pigs. A total of 160 barrows were used in a randomized completely block design and assigned to 4 treatments for a 7-wk study. Depending on the feeding phase, diets differed in dietary calcium (Ca) and phosphorus (P) levels (positive control [PC]: 8 to 6.8g/kg Ca; 7.3 to 6.3 g/kg P; negative control [NC]: 5.5 to 5.2 g/kg Ca; 5.4 to 4.7 g/kg P). NC diets were supplemented with phytase at 0 (NC); 500 (NC + 500 FTU); or 2,000 FTU/kg (NC + 2,000 FTU) phytase units/kg. Blood was collected after fasting (day 48) or feeding (day 49) for measurement of plasma inositol concentrations. On day 49, 2 pigs per pen were euthanized, and duodenal and ileal digesta samples were collected to determine inositol phosphates (InsP6-2) concentrations. High phytase supplementation increased BW on days 21, 35, and 49 (P < 0.05). Over the entire feeding period, ADG, ADFI, and feed efficiency were increased by NC + 2,000 FTU compared with the other treatments (P < 0.05). Postprandial plasma inositol concentration was increased in NC + 2,000 (P < 0.01), but there was only a tendency (P = 0.06) of a higher fasting plasma inositol concentration in this group. Inositol concentrations in the portal vein plasma (day 49) were not different among treatments. Duodenal digesta InsP5 and InsP6 concentrations were similar in PC and NC, but higher in these 2 treatments (P < 0.05) than those supplemented with phytase. Phytase supplementation decreased InsP6-4, resulting in increased InsP3-2 and myo-inositol concentrations. Similar effects were found in ileal contents. Compared with NC, phytase supplementation resulted in greater cumulative InsP6-2 disappearance (93.6% vs. 72.8% vs. 25.0%, for NC + 2,000 FTU, NC + 500 FTU and NC, respectively, P < 0.01) till the distal ileum. Longissimus dorsi muscle plasma membrane GLUT4 concentration was increased by NC + 2,000 FTU (P < 0.01) compared with NC. In summary, high phytase supplementation increased growth performance of nursery pigs. The higher myo-inositol release from phytate could contribute to the increased expression of GLUT4 in muscle plasma membranes. Further investigation is needed to determine whether this is associated with enhanced cellular glucose uptake and utilization.
