Short Term Effects Of Sildenafil In Treatment Of Pulmonary Hypertension In Degenerative Mitral Valve Disease Dogs, Karun Saetang

Chulalongkorn University Theses and Dissertations (Chula ETD)

Degenerative mitral valve disease (DMVD) is the most common acquired cardiac disease in small breed dogs. Pulmonary hypertension (PH) is a common complication in DMVD that can worsen the clinical signs, cardiac function, and median survival time of DMVD dogs. Conventional therapy of DMVD can reduce systolic pulmonary arterial pressure (sPAP) minimally. Thus, additional therapy is required. Sildenafil is used to treatment of PH in various causes, but the effect of sildenafil in the treatment of PH secondary to DMVD is not published yet. Therefore, this study aimed to evaluate the effects of sildenafil in combination with conventional therapy in …

Institutional Dynamics And Adaptive Capacity In World Heritage Management: Case Studies From Southeast Asia, Montira Unakul

Chulalongkorn University Theses and Dissertations (Chula ETD)

Over the past 40 years, heritage site management institutions have had to contend with expanding “boundaries of practice”: the evolution of heritage concepts and the emergence of global and transnational threats and broader sustainable development issues. Yet, many heritage site management institutions are still mired in conventional heritage mandates and approaches. This study looks at the ability of World Heritage site management institutions to adapt to this changing landscape. Global monitoring exercises show that World Heritage sites are struggling with this increased complexity, with many sites under active monitoring, sometimes for years. The sluggishness of change suggests that a deeper …

The Invention Of Plastic Plate For The Semiquantitative Detection Of Somatic Cells In Farm Bulk Tank Milk, Piyarat Jiarpinitnun

Chulalongkorn University Theses and Dissertations (Chula ETD)

Bulk tank milk somatic cell count (BTM SCC) is worldwide acceptable as an indicator of subclinical mastitis and milk quality at the farm level. Several countries determine the BTM SCC level for quality control and milk pricing. In Thailand, BTM SCC standard is set at 500,000 cells/ml and premium milk quality is set at less than 100,000 cells/ml. Milk collecting centers (MCCs) use CMT (California Mastitis Test) for screening raw milk quality. However, CMT has an error and high variation. This study aims to invent a new semiquantitative device for determining BTM SCC and to validate the device in comparison …

Assessment Of Left Atrial Function In Feline Hypertrophic Cardiomyopathy By Using Two Dimensional Speckle Tracking Echocardiography, Arisara Kiatsilapanan

Chulalongkorn University Theses and Dissertations (Chula ETD)

Hypertrophic cardiomyopathy (HCM) is one of the most common myocardial diseases in cats. The left atrial (LA) function plays an essential role in compensatory mechanism of left ventricle with diastolic dysfunction to maintain cardiac output in cats affected with HCM. Nowadays, there are several echocardiographic techniques used to evaluate the left atrial function; however, each technique has limitations. To overcome the limitations, two-dimensional speckle tracking echocardiography (2D-STE) is a novel technique for assessment the LA function. To date, no study focusing on assessment of the left atrial function by 2D-STE in feline HCM has been reported. The objective of this …

Correlation Of Allergen Specific Immunoglobulin To House Dust Mites And Commensal Microbes In Atopic Dogs And Identification Of Major Allergen In Dermatophagoides Farinae, Nathrada Khantavee

Chulalongkorn University Theses and Dissertations (Chula ETD)

To confirm a causative allergen in atopic dogs could test through intradermal skin testing (IDT) or allergen-specific IgE serology testing (ASIS). ASIS is more practical, convenient and safer. However, the results of ASIS could be affected by source and type of allergen. Crude allergen extracts were still used in commercial testing and protein antigens of skin microbes were not included in the panel of testing. In this study, our group developed serology test for confirming house dust mite allergy called Dermatophagoides farinae and D. pteronyssinus, and measuring specific immunoglobulin to skin microbes on dogs like Malssezia pachydermatis yeast and Staphylococcus …
