 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Age-Related Differences in Levels of Blood Chemistry Parameters and Cardiac Marker Proteins in Commercial Broilers) ผู้เขียน:นางชูศรี ศรีเพ็ญ, ผู้ช่วยศาสตราจารย์, ดร.อาภัสสรา ชูเทศะ, รองศาสตราจารย์, ดร.ทวีศักดิ์ ส่งเสริม, ศาสตราจารย์, นายโฆษิต ศรีเพ็ญ, อาจารย์ สื่อสิ่งพิมพ์:pdf AbstractThe effect of age on levels of blood biochemical parameters in broiler chickens is largely unknown. The purpose of the present study was to investigate physiological alterations of blood chemistry variables in renal, liver, lipid and cardiac profile in commercial broilers at the age of 2(n=20) and 7 weeks (n=40). The results showed that compared with broiler chicks at the age of 7 weeks, those at the age of 2 weeks had significantly higher levels of blood urea nitrogen, creatinine, uric acid, triglycerides and the enzymes alanine aminotransferase and alkaline phosphatase. Older chicks, on the other hand, displayed significantly higher levels of total protein, albumin, total cholesterol and the enzyme gammaglutamyl transferase. Although a significantly higher activity of cardiac enzyme aspartate aminotransferase and a significantly lower activity of lactate dehydrogenase were observed in older chickens, younger broilers exhibited a significantly higher concentration of the cardiac-specific marker troponin T. There was no significant age-related difference either in the levels of cardiac enzymes creatine kinase, creatine kinase MB or in glucose level. Cardiac troponin T concentration correlated significantly with that of CK-MB in both groups of animals studied. These results underline the importance of age as a significant contributor of variation in levels of several blood chemistry parameters and cardiac marker proteins, especially cardiac troponin T in broiler chicks. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Blood Chemistry Profile and Cardiac Troponin T Concentration in Thai Stray Dogs Infected with Heartworms) ผู้เขียน:นางชูศรี ศรีเพ็ญ, ผู้ช่วยศาสตราจารย์, ML.Narudee Kasemsant, ดร.สันติ แก้วโมกุล, ผู้ช่วยศาสตราจารย์, นายโฆษิต ศรีเพ็ญ, อาจารย์ สื่อสิ่งพิมพ์:pdf AbstractTo investigate blood chemistry profile and to determine levels of myocardial marker proteins in canine dirofilariasis, measurements of biochemical parameters in liver and renal profile as well as the activity of the enzyme creatine kinase (CK) and cardiac troponin T (cTnT) concentration were performed on 72 Thai stray dogs with and without the presence of heartworms. The results showed that, with the exception of the low levels of gamma-glutamyl transferase (GGT) and uric acid, levels of other blood chemistry variables are comparable to those obtained from human subjects. The relatively high activity of CK observed was probably due to skeletal muscle injury occurred during restraint of animals. The majority of dogs, on the other hand, exhibited virtually non-detectable cTnT concentration comparable to those observed in apparently healthy persons. Furthermore, there was no statistically significant difference in cTnT levels between asymptomatic dogs with and without the presence of heartworms. These results may provide a basis for future clinical studies on assessing the extent of myocardial cell damage in symptomatic heartworm disease. |
