Senthil; Jayathangaraj, M.G.; TANUVASThe sternum of Spot-billed pelican was large, broad and quadrilateral in shape. The sternal crest was small, triangular in shape and extended upto cranial half of the ventral surface only. The cranial border of the sternal crest was straight, and extended beyond the cranial border of the sternum. The hypocledium was fused to the ventral part of the cranial border of the sternal crest permanently. The cranial border presented a deep groove in the centre and narrow grooves on either side for coracoid bones. The sternal spine extended only from the ventral edge of the groove of the cranial border. The craniolateral processes were short. The lateral borders had five articular cylinders for sternocostal bones. Numerous pneumatic foramina were present between the articular cylinders. The caudolateral processes were short. The caudal border presented a short process in the centre. The clavicles were fused to the cranial border of the sternal crest.PresentationItem Open Access Gross Anatomical Studies“ On The Viscera Of Barking Deer (Muntiacus Muntjak)(TANUVAS, Chennai, 2010-02) Sathyamoorthy, O.R.; Thirumurugan, R.; Jayathangaraj, M.G.; Palanivelrajan, M.; Satheeshkumar, K.; TANUVASMuntjac is a true deer native to India, South East Asia and Sri Lanka. The male may attain a body weight of 20-35 kg. The female has a body weight of 13-15 kg. The colour ranges from grayish brown or reddish to dark brown.ArticleItem Open Access Histological and Histochemical Studies on the Glands of Skin of Madras Red Sheep(Indian Veterinary Journal, 2011-08) Ahmad, Mir Shabir; Sathyamoorthy, O.R.; Ramesh, Geetha; Basha, Sabiha H.; TANUVASThe sweat glands were simple, coiled and tubule-acinar noticed at the junction of papillary layer and reticular layer. Myoepithelial cells were noticed between the secretory cells and the basement membrane. In adult animals, the gland acini were supported by slightly thicker connective capsule than the young animals.ArticleItem Open Access Histological and Histochemical Studies on the Right Moderator Band of Pigs(Indian Veterinary Association, 2008-06) Sathyamoorthy, O.R.; Ramesh, Geetha; Ushakumary, S.; Basha, Sabiha Hayath; Vairamuthu, S.; TANUVASIn cardiac surgery porcine cardiac valves have been utilized for many years in the surgical replacement of diseased human valves. More recently, the pig has swept to the forefrcnt of transplantation medicine, with the development and successful breeding of transgenic pigs having human genes.ArticleItem Open Access Histological Observations On the Capsule and Connective Tissue Stroma Of Mammary Gland in Madras Red Sheep [Ovis Aries)(2014-05) Paramasivan, S.; Ramesh, Geetha; Ushakumary, S.; Kumaravel, A.; Sathyamoorthy, O.R.; Sivagnanam, S.; TANUVASThe mammary gla.nd in Madras red sheep was covered from outside to inside by the skin and fibroelastic capsule. The connective tissue septa branched off from capsule and grovm deeper and penetrated the adipose tissue which was evident in the mammary glands of prepubertal and pubertal animals.ThesisItem Open Access Histology and Histochemistry of the Skin of Madras Red Sheep (Ovis aries)(TANUVAS, 2009) Ahmad, Mir Shabir; TANUVAS; Sathyamoorthy, O.R.; Ramesh, Geetha; Balachandran, CArticleItem Open Access In vitro Culture and Morphometry of Porcine Adipose Derived Mesenchymal Stem Cells (pAD-MSCs)(Indian Journal of Animal Research, 2022-01) Singh, Thokchom Shitarjit; Sathyamoorthy, O.R.; Eswari, S.; Basha, Sabiha Hayath; Parthiban, M.; TANUVASBackground: Mesenchymal stem cells are well known for their self-renewal capacity and ability to differentiate into multiple cell lineages. The aim of the study was to develop a simple technique for isolation of mesenchymal stem cells from porcine adipose tissue and to study the morphometric characteristics of porcine mesenchymal stem cells. Methods: Porcine adipose derived mesenchymal stem cells were isolated in vitro by using collagenase type II enzyme. Cell yield and viability of the cells were calculated by using trypan blue exclusion method using Neubauer’s chamber. Characterization of MSCs were done by using specific cell markers. The morphological changes, morphometry were analysed in culture using Leishman’s stain. The cell doubling (CD) and Population doubling time (PDT) were also calculated. Result: The isolated adherent cells start forming colony and demonstrated an elongated, round and spindle like fibroblastic morphology by day 1. Almost 80-90 per cent confluency was attained on day 8-9 after the initial seeding and was reduced to day 3-4 in the subsequent passages. RT-PCR reactions revealed positive expression of mesenchymal stem cell markers CD44, CD73 and negative expression of CD34, a hematopoietic cell surface marker. Immunocytochemistry also revealed positive expression for CD44 and negative for CD34. In morphometric studies, the cell length, nucleus length, cell width and nucleus width were increased between 24 and 48 hours in both P2 and P3.ThesisItem Open Access Microanatomical Studies on the Thyroid Gland of the Japanese Quail(TANUVAS, 1996) Sathyamoorthy, O.R.; TANUVAS; Vijayaraghavan, C.; Venkatakrishnan, A.; Cyrus, InbarajArticleItem Open Access MICROMETRICAL STUDIES ON THE SKIN OF MADRAS RED SHEEP (OVIS ARIES) IN DIFEERENT AGE GROUPS(TANUVAS, 2011-01) Ahmad, Mir Shabir; Sathyamoorthy, O.R.; Ramesh, Geetha; Balachandran, C.; TANUVASMicrometrical studies on the skin of Madras red sheep was conducted in neonatal, young and adult age groups. The skin was the thickest on the neck dorsal region and thinnest on the thorax ventral region, in all the age groups studied. The epidermis on the dorsal regions was found to be slightly thicker than the lateral and ventral regions of neck, thorax and loin. From neonatal to adult age group animals, the dermal thickness was found to be increased in all the regions in the present study. The diameter of primary hair follicle was more than the secondary hair follicle and also the location of primary hair follicle was deeper to secondary hair follicle.
