Chulalongkorn University Theses and Dissertations (Chula ETD)
This study aimed at determine prevalence and concentration of Streptococcus suis contamination in pork production chains as well as evaluate the health risk attributable to S. suis serotype 2 from pork consumption in Thailand. In total, 492 pig-to-pork and 480 environmental samples were collected from 4 pork production chains in Bangkok. Besides, total 1,036 pork samples were also collected from traditional and modern trades in Chiangmai, Phayao, Nan, Khonkaen, Mukdahan, Saraburi, Nakhonpathom, and Phang-nga provinces. All samples were enumerated using plate count method. S. suis isolates were confirmed by detecting cps2-j gene, followed by Quellung reaction. A stochastic risk assessment …

Chulalongkorn University Theses and Dissertations (Chula ETD)
Risk estimates are evaluated by using quantitative microbial risk assessment (QMRA) which is a scientific tool. The methodology can be applied to model of human adverse health effect associated with K. pneumoniae and ciprofloxacin-resistant K. pneumoniae (CRKP) from pork consumption in Bangkok. This study had four phases which were 1) sample collection, 2) bacterial isolation and enumeration, 3) antimicrobial susceptibility test and 4) risk assessment. A total of 378 pork samples from fresh markets were collected from six Bangkok areas which contained Central Bangkok, Eastern Bangkok, Northern Bangkok, Southern Bangkok, Upper Thonburi and Lower Thonburi. The mean prevalence of K. …
Application Of Autologous Blood-Derived Platelet-Rich Fibrin For Periodontitis Treatment In Dogs, Chatvadee Kornsuthisopon
Application Of Autologous Blood-Derived Platelet-Rich Fibrin For Periodontitis Treatment In Dogs, Chatvadee Kornsuthisopon
Chulalongkorn University Theses and Dissertations (Chula ETD)
Periodontitis is one of the most prevalent inflammatory oral diseases in dog. Non-surgical managements are conventionally performed to obtain healthy oral status. With progressive periodontitis, advanced periodontal surgery and also dental extraction become warranted with major disadvantages of trauma, bleeding, prolonged anesthetic time and hospitalization, and wound healing impairment. Hence, use of platelet-rich fibrin has been studied and considered one of the novel approaches to augment in periodontitis management. This study aimed to evaluate the efficacy of autologous blood-derived platelet-rich fibrin in an aspect of periodontitis treatment in a canine models. In this study, the experiment was done at maxillary …

Chulalongkorn University Theses and Dissertations (Chula ETD)
Brachycephalic airway obstruction syndrome (BAOS) is life threatening condition in brachycephalic dogs. Surgical correction of primary disorders including elongated soft palate and stenotic nares is indicated in all cases. Aim of this study was to compare the use of the ultrasonic scalpel with the conventional incision technique for staphylectomy. Twenty dogs with BAOS enrolled in this study were randomly assigned into conventional (N=10) or ultrasonic group (N=10). Respiratory score was evaluated and recorded prior to surgery. Staphylectomy time and bleeding were recorded. Respiratory, postoperative complication and pain scores were evaluated and recorded at days 1, 3, 7, 14 and 28 …

Effects And Mechanisms Of Porcine Reproductive And Respiratory Syndrome Virus (Prrsv) Type 1 And Type 2 On The Permeability And Viability Of Porcine Endometrial Epithelial Cells, Dran Rukarcheep
Chulalongkorn University Theses and Dissertations (Chula ETD)
Both PRRSV types 1 and 2 revealed the sign of reproductive disorders associated with a lesion at implantation sites. Impairment of maternal glandular endometrium cell integrity and function by PRRSV infection may impact a proper nourishing fetus. This research was aimed to examine the effects of PRRSV type 1 and type 2 directly on the viability and barrier function of the endometrium using porcine glandular endometrial epithelial cell culture (PEG). The comparison of the route and the strain of PRRSV infection coinciding with their virulent in reproductive epithelia were considered. PEG cells isolated from the 4-6 months old PRRSV-free-herd gilts …
Potentials Of Ivabradine To Improve Cardiac Function In Dogs With Naturally Occurring, Asymptomatic Degenerative Mitral Valve Disease, Prapawadee Pirintr
Potentials Of Ivabradine To Improve Cardiac Function In Dogs With Naturally Occurring, Asymptomatic Degenerative Mitral Valve Disease, Prapawadee Pirintr
Chulalongkorn University Theses and Dissertations (Chula ETD)
The main hypothesis of the present study is that ivabradine (1.0 mg/kg, orally, twice daily) can reduce heart rate (HR), myocardial oxygen consumption (MVO2) and improve cardiac function in dogs with degenerative mitral valve disease (DMVD) partly due to a reduction of cardiomyocyte apoptosis. In order to test the hypothesis, this study was divided into three parts. The first part aimed to determine the appropriate single oral dose of ivabradine for reduction of HR and MVO2 as assessed by rate-pressure product (RPP= HR x systolic blood pressure). Once the appropriate dose was achieved, the second part was conducted to investigate …

Effects Of Short-Term Growth Hormone Administration On Plasma Leptin Levels In Normal And Diet-Induced Obesity Rats, Sutharinee Likitnukul
Chulalongkorn University Theses and Dissertations (Chula ETD)
Obesity has related to the alteration of hormonal profiles, i.e. growth hormone (GH), insulin and leptin. Because of the pleiotropic mechanisms of GH, it plays important roles both in the pathophysiological mechanisms and the therapeutic hormonal supplementation, which probably affected plasma leptin. The present research aimed firstly to demonstrate the effect of short-term GH administration on plasma leptin in 3 conditions; basal, meal-induced and fasting condition, from the rats with different adipose tissue mass. Secondly, to investigate short-term effect of GH on insulin sensitivity and body adiposity in control, diet resistant (DR) and diet-induced obesity (DIO) rats. In this regard, …

The Protective Effect Of Hydroxyxanthone On The Leakiness Of Intestinal Epithelia By The Proinflammatory Cytokine Related To Bacterial Endotoxin, Wannaporn Chayalak
Chulalongkorn University Theses and Dissertations (Chula ETD)
Leaky gut characterized as decreased transepithelial electrical resistance and increased paracellular permeability to macromolecules is associated with several fatal diseases including sepsis. Pro-inflammatory cytokine IL-1β is a critical mediator of underlying mechanism through activation of myosin light chain kinase pathway. Blocking the inducible phosphorylated myosin light chain (p-MLC) indicates the successful treatment. Xanthones predominantly found in mangosteen (Garcinia mangostana) has been indicated as a potent anti-inflammatory action. Hydroxyxanthones (HDX), the major natural xanthones, have been recently synthesized in various forms. This study aimed to examine and screen the action of various forms of synthetic HDXs, in preventing the increased paracellular …

Association Of Porcine Cryptorchidism With Dna Parentage Test, Testicular Protein Expression And Testicular Proteomics, Nathamon Yimpring
Chulalongkorn University Theses and Dissertations (Chula ETD)
Cryptorchidism is one of the most common congenital abnormalities observed in boars. One of the important obstacles to produce good quality pork is cryptorchidism. Pigs with cryptorchidism cause defects in spermatogenesis, low conception rate and/or infertility. This odor can be the cause of economic loss because consumers reject to buy meat with boar taint and flavor. In fattening farm, multi-sire mating system is normally used. Molecular genetic techniques allow the possibility of testing on genetic and parentage control. This research aimed to study i. To optimize microsatellite markers and develop the DNA fingerprint technique used to identify the parentage of …
