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 …
