1. The application of Compont gel in chronic obstructive jaundice rats model
Abstract Purpose: To establish a new rat model, the pathogenesis of which is closer to the clinical occurrence of chronic obstructive jaundice with liver fibrosis. Methods: 90 SD rats were randomly divided into 3 groups. Group A common bile duct ligation, group B common bile duct injection compont and group C injection saline. The serum of three groups was

2. Melatonin effects on pulmonary tissue in the experimental model of Hepatopulmonary Syndrome
RESUMO Objetivo: Avaliar as alterações pulmonares de animais com Síndrome Hepatopulmonar (SHP), submetidos à ligadura de ducto biliar (LDB), bem como o efeito antioxidante da Melatonina (MEL). Métodos: Dezesseis ratos machos da espécie Wistar, divididos em quatro grupos: Sham, Grupo LDB, Grupo Sham + MEL e LDB + MEL. Foram avaliadas a histologia pulm

3. MULTIVARIATE ANALYSIS OF BILIARY FLOW-RELATED FACTORS AND POST-KASAI SURVIVAL IN BILIARY ATRESIA PATIENTS
RESUMO CONTEXTO: A atresia biliar representa a principal causa de colestase tratada cirurgicamente durante o período neonatal. Se a criança não for operada, ela evolui invariavelmente para cirrose biliar secundária. OBJETIVO: Avaliar, através de análise multivariada, os fatores prognósticos associados à presença de fluxo biliar e à sobrevida co

4. Ray Tracing and Applications to an Evaporation Duct Model Based on Data from Oceanographic Buoy Sensors
Abstract The two-dimensional ray tracing method allows an easy and fast modeling of tropospheric propagation in the microwave frequency range. A version of this method that determines ray trajectories, amplitudes and delays of the electromagnetic field, as well as the propagation loss in a two-dimensional inhomogeneous environment will be described. The impl

5. Stability Characteristics of a Model Trim Adjustment System for Open Loop Active Control of Thermoacoustic Instability
ABSTRACT Thermoacoustic instability in liquid rocket engines can have potentially catastrophic consequences. Active control based on feedback promises improved stability margin over a wider range of operating conditions than passive control. In the present work, the thermoacoustic characteristics of a trim adjustment active control system based on variable v

6. Long-term effects of human amniotic membrane in a rat model of biliary fibrosis
Liver fibrosis is the most common outcome of chronic liver diseases, and its progression to cirrhosis can only be effectively treated with liver transplantation. The amniotic membrane (AM) has been studied as an alternative therapy for fibrosis diseases mainly for its favorable properties, including anti-inflammatory, anti-scaring and immunomodulatory proper

7. Effects of diazoxide in experimental acute necrotizing pancreatitis
OBJECTIVE: We aimed to assess the effects of diazoxide on the mortality, pancreatic injury, and inflammatory response in an experimental model of acute pancreatitis. METHODS: Male Wistar rats (200-400 g) were divided randomly into two groups. Fifteen minutes before surgery, animals received physiological (0.9%) saline (3 mL/kg) (control group) or 45 mg/kg

8. Effect of sılymarın on oxıdatıve stress and lıver hıstopathology ın experımental obstructıve jaundıce model
ABSTRACT PURPOSE: To investigate the effect of silymarin on oxidative stress and hepatic injury induced by obstructive jaundice in an experimental model. METHODS: Thirty Wistar-Albino type female rats were divided into 3 groups each including 10 rats. Only laparotomy was performed in group 1. Bile duct ligation was performed in group 2. In group 3, bile

9. A Histological Study on Venom Apparatus of Montivipera xanthina (Gray, 1849) (Serpentes, Viperidae)
ABSTRACT This is the first report describing morphological and histological structure of venom apparatus in Montivipera xanthina. The venom gland apparatus of M. xanthina was composed of four distinct parts, main venom gland, primary duct, accessory gland and secondary duct. The main venom gland was composed of acini. The accessory gland was formed by long a

10. Quercetin alleviates pulmonary angiogenesis in a rat model of hepatopulmonary syndrome
Quercetin shows protective effects against hepatopulmonary syndrome (HPS), as demonstrated in a rat model. However, whether these effects involve pulmonary vascular angiogenesis in HPS remains unclear. Therefore, this study aimed to assess the effect of quercetin on pulmonary vascular angiogenesis and explore the underlying mechanisms. Male Sprague-Dawley ra

11. Effects of temperature-dependent viscosity on fluid flow and heat transfer in a helical rectangular duct with a finite pitch
An incompressible fully developed laminar flow in a helical rectangular duct having finite pitch and curvature with temperature-dependent viscosity under heating condition is studied in this work. Both the cases of one wall heated and four walls heated are studied. The cross-sectional dimensions of the rectangular duct are 2a and 2b. The aspect ratio n=2b/2a

12. Surfactant protein A is decreased in the lung of rats with hepatopulmonary syndrome
PURPOSE:To evaluate surfactant protein A levels in an hepatopulmonary syndrome rat model. To date, there have been no studies aimed at evaluating surfactant levels in the setting of cirrhosis or hepatopulmonary syndrome.METHODS:A total of 35 rats were divided into control, sham, and experimental HPS groups. We evaluated surfactant protein A levels in rats an
