Abstrak: Daya antimikroba dalam madu dipengaruhi oleh kandungan glukosanya yang tinggi, tingkat keasaman madu, serta senyawa flavonoid yang dapat mengikat radikal bebas dan melawan agen infeksi. Eschericia coli dapat menimbulkan infeksi lokal organ tubuh, mencapai aliran darah, dan menimbulkan sepsis. Penelitian ini bertujuan untuk mengetahui perubahan gambaran histologik jaringan limpa tikus yang diinfeksi E.coli dan diberi madu. Penelitian ini merupakan penelitian eksperimental menggunakan 16 ekor tikus putih yang dibagi dalam satu kelompok kontrol negatif (KN) dan tiga kelompok perlakuan (KP). Kelompok kontrol negatif diberi pelet biasa selama 14 hari; KP 1 diberi pelet dan madu 2 mL/hari selama 35 hari; KP 2 diberi pelet dan E. coli 1 mL/hari melalui selama 7 hari; serta KP3 diberi pelet, E. coli 1 mL/hari selama 7 hari, dan madu 2 mL/hari selama 35 hari. Organ limpa tikus diproses untuk dibuat sediaan jaringan histologi. Jaringan limpa tikus KN dan KP1 menunjukkan gambaran histologik yang sesuai dengan limpa normal. Jaringan limpa tikus KP2 menunjukkan kongesti akut dan vasodilatasi pembuluh darah, sedangkan pada KP3 tampak kongesti yang lebih ringan dari yang terlihat pada KP2 dan adanya tanda regenerasi sel-sel limfohematopoietik jaringan limpa. Dengan demikian dapat disimpulkan bahwa kelompok perlakuan yang diberi E.coli tanpa pemberian madu menunjukkan suatu splenitis akut non spesifik, sedangkan kelompok perlakuan yang diberi E.coli dengan pemberian madu menunjukkan tanda-tanda perbaikan dari radang dan tanda regenerasi sel.Kata kunci: Madu, Eschericia coli, Limpa.Abstract: Antimicrobial force in his sugar content of honey is influenced by the high level of acidity of honey, as well as flavonoid that can bind free radicals and fight the infection agent. Eschericia coli can cause local infection of the body's organs, reaching the blood stream, and give rise to sepsis. This study aimed to determine changes in histological picture of the spleen tissue of mice given infected E.coli and gave honey. An experimental study using 16 rats divided into one negative control group (KN) and tree treatment groups (KP). Negative control group given normal pellets for 14 days. KP1 is given pellets and honey 2 mL / day for 35 days. KP2 are given pellets and E. coli 1 mL / day through 7 days. KP3 given pellets, E. coli 1 mL / day for 7 days, and honey for 35 days.

Curcumin has remarkable anti-inflammatory and antioxidant properties. The aim of this study was to investigate the protective effects of curcumin on a rat model of carbapenem-resistant Escherichia coli–induced acute lung injury (ALI). Thirty-two rats were randomly allocated to 4 groups to induce an ALI: negative control group (rats not infected with E coli with no antibiotic treatment), positive control group (rats infected with E coli with no antibiotic treatment), imipenem group (rats infected with E coli that received intraperitoneal injection of imipenem), and the imipenem+curcumin group (rats infected with E coli that received intraperitoneal injection of imipenem and were fed on curcumin).The rats were killed, and lung tissues samples were harvested for biochemical analyses and histopathologic examination. Total antioxidant status (TAS), total oxidant status (TOS), tumor necrosis factor α (TNFα), and interleukin-6 (IL6) were measured. TOS increased in the positive control group (P < 0.001) and decreased in the imipenem and imipenem+curcumin groups (P < 0.001 and P < 0.001, respectively). TAS decreased in the positive control group (P = 0.005). Imipenem treatment did not increase TAS, but the imipenem+curcumin group increased TAS (P = 0.014). TNFα and IL6 increased in the positive control group compared with the negative control group (P < 0.001 and P = 0.010, respectively). Imipenem decreased TNFα (P < 0.001), but did not decrease IL6 (P = 0.418). Imipenem+curcumin decreased TNFα (P < 0.001); this decrease was more pronounced compared with the imipenem group (P = 0.008). IL6 decreased in the curcumin group compared with the positive control group (P = 0.011). Curcumin combined with imipenem can be an alternative therapeutic agent to overcome the resistance of E coli strains.

Consuming time and effort to prepare hyperimmune globulins using Freund’s adjuvant is a sophisticated and harsh technique. In this work, a novel, safe, and rabid method was proposed using monolaurin as an immune-stimulating agent in hyperimmune globulins production against Bovine coronavirus (BCoV). The mentioned virus was used as a surrogate to family Betacoronavirus. Bovine coronavirus (Mabus strain) with titer log10 5.8 tissue culture infective dose infectivity (TCID50)/ml was used in this experiment. The inactivation of the virus was done using 1% ascorbic acid for 24h. Monolaurin emulsion (10% w/v) of was prepared by sonication using tween 20 and water. The inactivated bovine coronavirus was added to the emulsion by 20% of the final volume. The immunoglobulins were prepared by inoculating the inactivated virus with the adjuvant in rabbits and evaluated on the Madin-Darby bovine kidney (MDBK) cell line by virus neutralization test (VNT). The effect of the adjuvant was assessed by histopathological examination of vital organs such as the kidney and liver. The antibody titer against the BCoV was reached its peak, log2 1024 TCID50/ml, at the 3rd-week post-inoculation in the rabbits. The level of the globulin reached a high level and its peak (14.3g/dL) at the end of the experiment. No abnormalities were seen in the livers and kidneys of the negative control group of rabbits. Monolaurin showed a new level of safety and efficacy when used as an adjuvant during the preparation of the immunoglobulins against BCoV.

Background and Aim: Escherichia coli is the cause of avian colibacillosis, a significant threat to the poultry industry and public health. Thus, this study investigated the prevalence of E. coli in diseased chicken broilers, pathological effects of these bacteria, and interleukin (IL) gene expression of different serotypes of E. coli (O78, O26, O44, and O55) on experimentally infected chickens. Materials and Methods: A total of 295 organ samples (liver, lungs, heart, and spleen) from 59 diseased broiler chickens were used for conventional identification of E. coli. Chickens were orally infected with one of the following E. coli serotypes (O78, O26, O44, or O55) and examined for clinical signs, mortality, macroscopic and microscopic lesions, and IL gene expression using real-time quantitative polymerase chain reaction. Results: E. coli was isolated from 53.2% of broiler chicken organs with a high prevalence in lungs (26.1%). The most prevalent serotypes were O78, O26, O44, O55, O157, and O127 prevalence of 27.8, 22.2, 16.7, 16.7, 5.6, and 5.6%, respectively. In the experimental design, five groups (G1-G5) of birds were established. G1 served as the negative control group, while G2-G5 were challenged orally with E. coli O78, O26, O55, or O44, respectively. Chickens infected with E. coli O78 or O26 showed significant clinical signs in comparison to the other infected birds. Mortality (13.3%) was only observed in birds infected with E. coli O78. Necropsy of dead birds after E. coli O78 infection showed pericarditis, enteritis, airsacculitis, and liver and lung congestion. More severe histopathological changes were observed in intestines, spleen, liver, and lung from chickens infected with either E. coli O78 or O26 than for birds infected with other serotypes. On the 2nd day post-infection, E. coli challenge, particularly with E. coli O78, displayed significantly upregulated levels of ileal IL-6 and IL-8, but ileal IL-10 level tended to be downregulated in comparison to the control group. Conclusion: This study assessed the application of cytokines as therapeutic agents against infectious diseases, particularly colibacillosis.

In this study, the protective efficacy of an E. coli live attenuated vaccine was compared to the preventive administration of lectin preparation before the challenge. Two hundred broiler chicks were divided into eight equal groups. The first group was used as a negative control group. Three groups were vaccinated at day 1 with the avian colibacillosis live vaccine of which one group served as a vaccinated nonchallenged group. Another two groups were treated with lectin product (0.5 mL/L drinking water) for three days before the challenge. The last two groups served as challenge control for either E. coli O78 or O125 strains. The challenge was conducted at three weeks of age with either homologous O78 or heterologous O125 E. coli strains, using 0.5 mL/bird of each avian pathogenic E. coli (APEC) strain (~108 colony forming units “CFU”/mL)/subcutaneously. The bodyweight and feed conversion ratios (FCR) were calculated for four weeks. Clinical signs and gross and histopathological lesions were scored at two and seven days post inoculation (dpi). The heart and liver of euthanized chickens at 2 dpi were removed aseptically and homogenized to evaluate pathogenic E. coli colonization. Results showed that live avian colibacillosis vaccine reduced mortalities and APEC colonization in the homologous challenge group but not in the heterologous challenge group. Lectin-treated groups showed 20% and 16% mortality after challenge with E. coli O78 and O125, respectively, and both groups showed performance parameters, clinical signs, and histopathological lesion scores comparable to the negative control group, with variable E. coli colonization of heart and liver. The study demonstrated the efficacy of live attenuated avian colibacillosis vaccine against homologous but not heterologous APEC challenge in broiler chickens. The lectin-containing products can be used as a preventive medication to reduce the clinical impacts of colibacillosis regardless of the challenge strain. Standardization of the evaluation parameters for APEC vaccines is recommended.

The aim of this study is to investigate the antitumor activity of Plantago major L. extract in Ehrlich ascites tumor (EAT) bearing Balb/C mice in vivo. Thirty male Balb/C mice were divided into 5 groups: 3 treatment groups and 2 control groups (6 per group). Treatment groups and the negative control group were injected with EAT (1 × 106 cells) intraperitoneally to develop ascites tumor. P. major L. extract (1%, 2% and 3% concentration extracts, 0.1 ml/day/mouse) were given p.o. for 10 alternate days. The control group was treated with 0.9% NaCl solution (0.1 ml/day/mouse). The changes of body weight in animals were recorded. On the 11th day, all of the mice were sacrified and their tissues were stained with haematoxylen and eosin for pathological studies. Body weights of in 3 treatment groups and the negative control group were elevated because of tumor burden. The maximal weight gain was recorded in the negative control group and the minimal weight gain was recorded in Group I. Pathological studies showed that P. major L. extract (especially 1% concentration) has inhibitive effect on EAT. P. major has an inhibitory effect on EAT in a dose dependent manner.

Abstract Osteoporosis is a bone disease characterized by decreased quality and strength of bones so that it becomes porous and fracture. Propolis is known to have many pharmacological activity, including an anti-osteoporosis effect. This study aims to determine the effect of propolis administration and the effects of propolis dosage variation in preventing osteoporosis based on the strength value of femur bone impact in female white rats in the form of an ovariectomy postmenopausal model. The rats were divided into 5 groups: positive control group (subjected to ovariectomy), negative control group (not subjected to ovariectomy, and treatment groups that were subjected to ovariectomy and given propolis at a dose of 180 mg/kg BW, dose 360 mg/kg BW and dose 720 mg/kg BW. Propolis was administered orally for 30 days. Bone impact strength testing was undertaken after 30 days using an impact testing machine. Research data were analyzed via one-way ANOVA and continued with the Duncan’s Multiple Range Test. From the test results, we noted that propolis administration had an effect on the value of bone strength, with the dose of 720 mg/kg BW and 360 mg/kg BW having a significant effect, compared with others. With an increase in dose, propolis can provide an increase in the value of bone strength in rat bones.
