ArticleItem Open Access Abnormal renovascular resistance in dogs with diabetes mellitus: correlation with glycemic status and proteinuria(2018) Priyanka, M; Jeyaraja, K; Thirunavakkarasu, PS; TANUVASPresent study was conducted with the objectives of determining the renal vascular resistance in dogs with diabetes mellitus and to study the correlation between the indices of renovascular resistance with glycemic status, systolic blood pressure (SBP) and proteinuria in dogs with diabetes mellitus. This study was conducted on seventeen diabetic dogs and ten apparently healthy dogs. Increased renal resistive index (RI) and pulsatility index (PI) were observed in diabetic dogs as compared to healthy dogs. Systemic hypertension and proteinuria were observed in 10 and 3 out of 17 diabetic dogs, respectively. Significant positive correlation was observed between the indices of renovascular resistance and fasting blood glucose levels and between the indices of renovascular resistance and serum glycated hemoglobin levels. No correlation was observed between the indices of renovascular resistance and SBP as well as the indices of renovascular resistance and proteinuria. As the indices of renovascular resistance correlate significantly with glycemic status, they can be used as the early marker for kidney damage in diabetic patients. Among these indices renal PI was found to be more sensitive than renal RI.ArticleItem Open Access Aural haematoma in a rabbit: a case report(2008) Vijayanand, V; Gokulakrishnan, M; Thirunavakkarasu, PS; Rajasundaram, RC; TANUVASAural haematoma is an excessive collection of blood within a fractured auricular cartilage. It is usually caused by injury to a superficial vein.ArticleItem Open Access Cystic Endometrial Hyperplasia in a Splitz(2011) Vijayanand, V; Gokulakrishnan, M; Thirunavakkarasu, PS; Rajasundaram, RC; TANUVASCystic Endometrial Hyperplasia is a disease if middle aged cycling bitches generally occurring 6-8 weeks after oestrus with a more common occurence in nulliparous bithces (Dow, 1958) influenced by the action of progesterone hormone progressing to pyometra resulting in infertility.ArticleItem Open Access Fetal anasarca in a Dachshund pup: a case report(2008) Gokulkrishnan, M; Vijayananad, V; Thirunavakkarasu, PS; Rajasundaram, RC; TANUVASFetal anasarca (Water Puppy Syndrome) is a condition characterized by severe whole body subcutaneous edema of the fetus due to abnromal accumulation of serous fluid various organs, cavities or tissues of the body resulting in dystokia (Wallace et al, 1995).ArticleItem Open Access Pulsed Wave Doppler and Color Flow Doppler Evaluation in Healthy Dogs and Dogs with Cardiac Disease(Cloud Publications, 2016-07) Jeyaraja, K; Hamsa, S. Yamini; Thirunavakkarasu, PS; TANUVASDoppler echocardiography gives a physiological assessment of blood flow within the cardiac chambers, across valve orifices and in the great vessels. Pulsed wave Doppler can detect flow pattern in a very discrete region of simultaneously imaged 2-D echocardiographic plane. Twenty apparently healthy dogs and twenty affected dogs with dilated cardiomyopathy and mitral valve insufficiency ten each were selected for the study and subjected to detailed color flow and pulse wave Doppler study. In color flow Doppler studies a normal mitral and tricuspid flow were red in color as the flow is towards the transducer and when the nyquist limit exceeded it had a layers of blue superimposed on it. Aortic flow was seen as hues of blue and red and because of depth of the aorta nyquist limit was low and aliasing was commonly seen. In pulmonary flow the flow was usually blue in color as it was away from the transducer and total reversal of color was often seen as flow progress from high velocity during early systole to the lower velocities at the end of systole. In mitral valvular insufficiency two out often dogs showed jet occupying less than 20 per cent of atrium, three out of ten dogs showed jet occupying 20-50 per cent of atrium and five out of ten dogs showed jets occurring more than 50 per cent of atrium. In dilated cardiomyopathy mild to moderate jets were appreciated in four out of ten dogs in both mitral and tricuspid valves and two out of ten dogs showed mitral regurgitation alone.ArticleItem Open Access TRAUMATIC ORCHITIS IN A KID - A CASE REPORT(2009-06) Gokulakrishnan, M; Vijayanand, V; Thirunavakkarasu, PS; Rajasundaram, RC; TANUVASOrchitis is inflammation of the testicular tissue occurring in all species. The factors involved in its etiology may be either traumatic or infectious. A case of traumatic orchitis in a kid is reported.
