The Thai Journal of Veterinary Medicine

Canine primary hypothyroidism is one of the most common endocrinopathy diseases in dogs affecting various body systems. In veterinary practice, the measurement of total thyroxine together with canine thyroid-stimulating hormone (TSH) was suggested to have high accuracy for diagnosing this disease. However, the changes in these recommended diagnostic parameters can be distinguished only in a hypothyroid dog with progressive deterioration or later in the disease. This study investigated the relevant predicting factors of canine primary hypothyroidism from animal characteristics and blood chemistry. Among the 672 dogs that met the inclusion criteria, 77 dogs had hypothyroidism and 179 had non-hypothyroidism. Age …

The Thai Journal of Veterinary Medicine

Cranial cruciate ligament rupture (CrCLR) and medial patellar luxation (MPL) are common problems that cause hindlimb dysfunction, lameness and pain in dogs. Although surgical intervention is recommended for these conditions, it may not be suitable for an individual with some underlying diseases. The objective of the present study was to compare the outcomes between surgical and non-surgical treatments for concomitant CrCLR and MPL in small-breed dogs. Seven stifles from five small-breed dogs with concomitant CrCLR and MPL were enrolled and divided into two groups. Four limbs (three dogs) in Group 1 were treated conservatively, and three limbs (two dogs) in …

Development Of A Preliminary Clinical Approach For Detecting Insulin Resistance For Normoglycemic Control In Canine Diabetes, Chutirat Torsahakul

The Thai Journal of Veterinary Medicine

Consistent and effective blood glucose (BG) control is crucial in the treatment of diabetes mellitus (DM) and insulin resistance (IR). In this study, the surrogate indices for monitoring insulin sensitivity and the preliminary clinical approach for detecting IR were established. Fasting serum C-peptide was measured by a commercial enzyme-linked immunosorbent assay (ELISA) kit and utilized as an endogenous insulin representation. The homeostasis model assessment of insulin resistance (HOMA-IR) was then calculated. To detect the IR, the relationship between HOMA-IR and fasting serum C-peptide in each individual subject was analyzed, and designed cut-off values. The results revealed that the HOMA-IR of …

The Thai Journal of Veterinary Medicine

The round body shape and short legs of Bantam chickens (Gallus gallus) pose breeding challenges, making artificial insemination critical for these animals. To contribute to such assisted reproductive technology in avians, this study assessed the effect of a modified simple medium for assisted reproductive technology (SMART) extender on sperm longevity and frozen-thawed semen quality compared to the Blumberger Hahnen Sperma Verdünner (BHSV) extender. Sperm motility and viability were measured in 20 roosters at fresh and chilled conditions at 4-, 24-, and 48-hour intervals. For the subsequent freezing step, 6% and 9% DMA were added to both extenders as …

Challenging The Efficacy And Safety Of Clopidogrel Versus Aspirin Monotherapy In Secondary Prevention Of Coronary Artery Disease: A Comprehensive Review, Punyawee Boonthanomwong, Prayuth Poowaruttanawiwit

The Thai Journal of Pharmaceutical Sciences

Coronary artery disease (CAD) remains a major contributor to global morbidity and mortality, necessitating robust secondary prevention strategies. Antiplatelet therapy, particularly aspirin, has long been the cornerstone in CAD management, effectively reducing thrombotic events postacute coronary syndrome and in patients with chronic coronary syndrome. However, aspirin’s association with gastrointestinal (GI) bleeding and the emergence of alternative agents like clopidogrel have debate over the optimal monotherapy for CAD patients. Clopidogrel, a P2Y12 receptor antagonist, is increasingly considered a viable alternative, especially for patients at high risk of GI complications or aspirin intolerance. Recent clinical trials and updated guidelines have emphasized the …
