Animal Models with Metabolic Syndrome Markers Induced by High Fat Diet and Fructose
Metabolic syndrome is lipid and non-lipid metabolism disorder due to the association of several factors such as physiological, clinical, biochemical, and interrelated factors. People with metabolic syndrome can be diagnosed by fulfilling 3 of 5 criteria, including obesity and increased waist circumference, increased TG levels, increased blood pressure, hyperglycemia, and increased High-Density Lipoprotein (HDL) serum. The high-fat diet disrupts tissue lipid metabolism, so insulin resistance occurs due to lipotoxicity. Besides, some studies use a combination of mixtures (fructose, sucrose) and fat-rich food components to build metabolic characteristics in mice that affect human characteristics. The purpose of this study was to make an animal model with a metabolic syndrome marker induced by the High Fat Diet (HFD) consisting of pork oil and chicken egg yolk, as well as fructose from simple and economical ingredients. This study was an experimental study using experimental animals of male Rattus norvegicus strain wistar, which were grouped into three random treatment groups, namely the control group, HFD group, and High Fat Diet Fructose (HFDF) group. The number of samples used was 27 rats, with nine rats in each group. The animal was induced for four weeks, then measured levels of FPG, HD, and TG. From the research that has been done, it is found that there are significant differences in levels of Fasting Plasma Glucose (FPG), High-Density Lipoprotein (HDL), and Triglycerides (TG) (
Effects of Prebiotics, Probiotics, and Synbiotics on the Bodyweight, Blood Glucose, Triglyceride and TNF-α of Diet-induced Obesity Rats
Abstract  High-fat diet leads to obesity-associated chronic low-grade inflammation. Prebiotics, probiotics, and synbiotics produced short-chain fatty acids (SCFA), bonded to G protein-coupled receptors (GPR)-41 and GPR-43 decreased triglyceride deposits in adipocytes and liver, decreased fatty acid oxidation, increased glucose regulation and insulin sensitivity thus reduced the risk of obesity and metabolic syndrome. This study conducted in order to evaluate the effects of prebiotics, probiotics, and synbiotics on the body weight, blood glucose, triglyceride, and TNF-α used rats model, which were fed by a high-fat diet. Thirty-eight 6-8 weeks old male rats were fed by high-fat diet for three weeks, then rats were randomly divided into four groups, high-fat diet (HFD), a high fat diet with prebiotics supplementation (HFD+ PRE), a high fat diet with probiotics supplementation (HFD+PRO), and high-fat diet with synbiotics supplementation (HFD+SYN) for three weeks. Blood samples and body weight were measured at the third and sixth week. There was no effect of prebiotics, probiotics, and synbiotics on body weight, triglyceride levels, blood glucose, and TNF-α in rats fed a high-fat diet compared to control. These results suggested that supplementations gave inconsistent results with other studies and needed further researches.Keywords            : high fat diet, prebiotics, probiotics, synbiotics, meta-inflammationCorrespondence  : [email protected]
The detection of Mycobacterium tuberculosis using in vitro granuloma tuberculosis model intracelluler specimens
The Granulomas are a group of innate and adaptive immune cells that are highly organized, and during tuberculosis infection caused by the bacterium Mycobacterium tuberculosis. Estimated as many as 1.6 million cases of death in 2017 according to World Health Organization. Tuberculosis ranks in the top 10 causes of death worldwide and it is predicted that more than 1.7 billion people (around 25 percent of the world's population) are estimated to be infected by Mycobacterium tuberculosis. The purpose of this study was to confirm the Mtb by examining a new method by modifying Ziehl-Neelsen stain using an intracellular specimens for tuberculous granuloma in vitro.

The result is Ziehl-Neelsen staining was modified, it was found that the Mycobacterium tuberculosis H37Rv as detection of bacterial confirmation is said to be successful
The Ventilation-to-area Ratio and House Lighting Relate to the Incidence of Pulmonary Tuberculosis
Background: Indonesia is one of the heavy burden countries with high pulmonary tuberculosis incidence in the world. The physical condition of houses is one of the environmental factors on how the infection spreads. The objective of this study was to provide supporting facts between the physical environment of the houses and the incidence of pulmonary tuberculosis.Methods: This was an observational analytic study with a case-control design, using checklists among pulmonary tuberculosis patients (n 32) and their healthy controls (n 32). Study subjects were chosen by simple random sampling. The study was performed from March to August 2019 at the Public Health Center (Pusat Kesehatan Masyarakat, Puskesmas) in Sawahan district, Surabaya. The incidence of pulmonary tuberculosis was related to various factors, including window existence, window opening habit, ventilation-to-area ratio, humidity, temperature, lighting, and occupancy density. The collected data were analyzed using the chi-square test to assess statistical significance with a p-value <0.05 was considered significantly related.Results: The ventilation-to-area ratio (p<0.05) and house lighting (p<0.00) were related to pulmonary tuberculosis incidence, whereas other factors such as window existence, window opening habit, temperature, and occupancy density were not.Conclusions: The ventilation-to-area ratio and house lighting have been proven to be related to pulmonary tuberculosis incidence. Government regulation on building permit needs to be encouraged to reduce the spreading and the incidence of pulmonary tuberculosis
Growth kinetics of multiple Acinetobacter baumannii resistotype after meropenem-based antibiotic combination exposure [version 2; peer review: 2 approved]
Background: Carbapenems are the treatment of choice for multidrug-resistant (MDR) and extensively drug-resistant (XDR) Acinetobacter baumannii infections, but the emergence of carbapenem-resistant A. baumannii (CRAB) has rendered it ineffective in the vast majority of cases. Combination therapy has grown in popularity over the last decade; this study aims to analyze A.baumannii growth kinetics after exposure to meropenem and ampicillin-sulbactam compared with meropenem and amikacin antibiotic combinations in clinically relevant concentrations. Methods: This experimental laboratory study was conducted on the A. baumannii ATCC 19606 isolate and three clinical isolates that were intermediate or resistant to tested antibiotics. Meropenem and ampicillin-sulbactam, as well as meropenem and amikacin, were tested at four different concentrations against isolates. Turbidity measurements were taken at predetermined time points of 0, 1, 2, 4, 6, 8, and 24 hours following exposure; bacterial concentration was enumerated using the agar plate method, with the results plotted in a time-kill curve.  Results: A bactericidal effect was achieved in isolates that were intermediate to ampicillin-sulbactam and resistant to meropenem after the administration of meropenem and ampicillin-sulbactam combination with a concentration of 4 µg/ml and 16/8 µg/ml, respectively. The combination of meropenem and ampicillin-sulbactam demonstrated bacteriostatic activity against isolates that were resistant to both antibiotics. Isolates treated with resistant antibiotics showed an increased growth rate compared to the growth control. Conclusion: The combination of meropenem and ampicillin-sulbactam could be a promising combination therapy in treating CRAB infections. The mechanism and degree of antibiotic resistance in the isolates affect the efficacy of antibiotic combinations; further research is needed to corroborate the findings of this study
Perbedaan Ekspresi Caspase 3 pada Limpa Tikus Model Sepsis yang Diinfeksi Escherichia coli ESBL dan dengan yang Diinfeksi Klebsiella pneumoniae Carbapenemase
Sepsis adalah suatu sindroma klinik yang terjadi karena adanya respon tubuh yang berlebihan terhadap rangsangan produk mikroorganisme. Pasien sepsis dengan infeksi bakteri penghasil ESBL 57,4% terinfeksi E. coli, 21,35% terinfeksi Enterobacter sp, dan 21,3% terinfeksi Klebsiella sp. Sepsis dapat diperberat oleh peningkatan kuman yang multiresisten terhadap bermacam antibiotik, seperti E. coli ESBL dan K. pneumoniae carbapenemase (KPC). Selama infeksi bakteri, faktor virulen diproduksi dan disekresikan dari patogen dan memicu sinyal apoptosis. Penelitian mengenai caspase 3 dianggap penting, karena caspase 3 merupakan efektor caspase terpenting yang bertanggungjawab atas morfologi dan perubahan biologis yang terlihat pada sel apoptosis. Jenis penelitian ini adalah true experimental dengan rancangan penelitian post test only control group design. Hasil penelitian menunjukkan bahwa ekspresi caspase 3 pada limpa mencit yang diinfeksi KPC adalah 65,25±12,69%, sedangkan yang diinfeksi E. coli ESBL adalah 33,75±3,862%, hal tersebut diduga karena adanya kapsul polisakarida yang mengelilingi KPC dan melindungi dirinya terhadap aksi fagositosis dan bakterisidal serum yang dapat dianggap sebagai penentu virulensi paling penting dari KPC dan menyebabkan mitokondria melepaskan ROS. Infeksi bakteri tersebut menyebabkan mitokondria memproduksi ROS dan memicu pelepasan sitokrom c. Sitokrom c akan memicu caspase 9 untuk berikatan dengan efektor caspase 3, sehingga terjadi apoptosis

The Effect of Snakehead Fish (Channa striata) Extract on Inflammation Reaction of Skin Wound Tissue in Rattus novergicus Wistar Strain
Background: Snakehead fish has been associated with wound healing due to its high albumin content. Albumin can accelerate the inflammatory process so that tissue repair will be faster. Lack of albumin protein causes a person tend to experience prolonged wound healing. Purpose: This study aims to prove the effect of snakehead fish extract on the number of macrophages and blood vessels on the inflammatory reaction of skin wound tissue in rats. Methods: Laboratory experimental design with a total sample size of 27 male rats have undergone incisions, divided into 3 random groups: control group was given aquadest, treatment group 1was given aquadest and 50% extract of snakehead fish, and treatment group 2 was given 100% extract of snakehead fish. The rat’s skin wound tissues were taken on day 5 and observed under the microscope. The average number of macrophages and blood vessels on granulation tissue that formed at the base of the wound were counted and then performed data analysis. Result: In this study, we found a down wards trend in the average number of macrophages and blood vessels in treatment group 1 and treatment group 2. The control group and the treatment group 2 showed a significant difference, however, between the other groups did not show significant difference. Conclusion: There is a significant effect of giving 100% snakehead fish extract on decreased macrophages and blood vessels in the inflammatory reaction of skin wound tissue
Vancomycin For Methicillin-Resistant Staphylococcus Aureus Biofilm Eradication Is Associated With The Emergence Of Heterogeneous Vancomycin Intermediate Staphylococcus Aureus
Vancomycin is the first-line therapy for MRSA infections, even though the standard dose is inadequate for biofilm eradication. This study aimed to asses the efficacy of vancomycin in eradicating biofilms and the influence of exposure on the emergence of hVISA isolates. The biofilm formed by MRSA isolates was exposed to vancomycin concentrations of 1 times the MIC, 1,000 times the MIC, and 10,000 times the MIC; exposed continously for 24 hours vs intermittently for 6 hours/day for 3 days. Measurement of the optical density of the biofilm was carried out to determine the percentage of biofilm eradication. Biofilm specimens exposed to vancomycin were subcultured onto BHIA-VC selective media to isolate hVISA. The highest biofilm eradication effect was found in isolates exposed to vancomycin at a concentration of 10,000 times the MIC. Vancomycin exposure correlated with the emergence of hVISA isolates, especially after exposure to low concentrations of vancomycin. For optimum eradication of MRSA biofilms, vancomycin concentrations exceeding 1.000 times the MIC are required. Exposure to vancomycin at a dose equal to one-times the MIC had no effect on biofilm eradication and was associated with the emergence of MRSA isolates with decreased susceptibility to vancomyci
Perbandingan Distribusi Dan Pola Kepekaan Acinetobacter baumannii Terhadap Antimikroba Di RSUD Dr. Soetomo Surabaya Periode Januari–Maret 2015, April–Juni 2015, dan Januari–Maret 2016
Acinetobacter baumannii is an environmental bacteria that can cause opportunistic infections such as ventilator-associated pneumonia, burn wound infection, urinary tract infection, and sepsis in immunocompromised patients. A. baumannii infections are troublesome because the bacteria resistance to many antimicrobial agents. Surveillance of distribution and sensitivity pattern of A. baumannii is best to be done frequently in hospitals.Venous blood as much as 10 milliliters was drawn aseptically and transferred into liquid medium Bactec® to be sent to Clinical Microbiology Laboratory of Dr. Soetomo General and Teaching Hospital. Medium that showed bacterial growth was subcultured on Blood Agar Plate and MacConkey Agar, and incubated for 18-24 hours in aerobic condition. Identification and susceptibility test were done with semi-automated system BD Phoenix, and interpreted based onClinical and Laboratory Standards Institute 2015.A. baumannii collected on trimester January-March 2015 were 30 isolates, with 19 isolates being Multidrug Resistant(MDR) A. baumannii (63%) and 6 isolatesPandrug Resistant(PDR)A. baumannii (20%). Isolates from trimester April-June 2015 were 32 isolates, with 21 isolates being MDR A. baumannii (66%) and 2 isolates PDR A. baumannii (6%). Isolates from trimester January-March 2016 were 40 isolates, with 22 isolates being MDR A. baumannii (55%) and 2 isolates PDR A. baumannii (5%).A. baumannii mostly isolated from Intensive Care Unit, followed by Internal medicine ward, Pediatric ward, Surgery ward and Emergency Department. High sensitivity of A. baumanniion trimester January-March 2016 was to imipenem (50%), meropenem (50%), amikacin (53%), cotrimoxazole (53%), dan cefoperazone-sulbactam (55%).. MDRA. baumannii mostly isolated from ICU, which reflects high burden of antimicrobial use. At this moment, antimicrobial agents that can be used as empirical therapy for A. baumannii infection are imipenem, meropenem, amikacin, cotrimoxazole, and cefoperazone-sulbactam. The entire hospital member must implement the Infection Control and Prevention and Antimicrobial Stewardship Program to preventnosocomial infections byA. baumanniiand the emergence of MDRA. baumannii
