The objective of this study was to determine the anatomical morphology and histology of the intestineof water monitor (Varanussalvator). Intestine organ from an adult male water monito was used in thisstudy. Perfusion was performed to flow the 4% paraformaldehyde fixative solution through the heart.Intestine was collected, then divided into six sections, followed with dipping them into 4% paraformaldehydesolution for four days, continued histological preparations and stained with haematoxylin eosin (HE). Theanatomical morphology observation was performed before the intestine was processed into histologicalpreparations by observing the outer shape of the intestine and measuring it’slength. Morphologicalobservation was made †after processing theintestinal tissue by observing each portion of the intestinalwall structure. The results showed that transverse fold were found on the outer and inner surfaces of theintestine section I-IV, while in the V-VI part of the intestine, the folds were not observed anymore. Theintestine wall consisted of four layers, such as mucosa, submucosa, tunica muscularis, and serosa. Thevilli on intestine section I-IV were relatively longer and higher, while the intestine vili in section V-VI wererelatively short. The entire mucosa in water monitor was coated with absorptive columnar epitheliumwith goblet cells. Based on the result study, it can be concluded that the water monitor has more efficientdigestive process which can be seen morphologically from the relatively short intestinal, has transversefolds on the surface of the small intestine, and does not have cecum. The intestinal wall consists of layersi.e : mucosa, submucosa, tunica muscularis, and serosa.

The objective of this study was to determine the carbohydrate content of salivary glands lingual,sublingual, and mandibular glands of water monitor (Varanus salvator). This studywas used the lingualglands, sublingual, and mandibularof an adult male water monitor. Salivary glands were fixed by soakingin a solution of 4% paraformaldehyde for four days. Then, the tissuewas processed into routine histologicalpreparations. Salivary gland tissue was stained with alcianblue staining (AB) pH 2.5 for detecting acidiccarbohydrates and was stained with periodic acid Schiff (PAS) for detecting neutral carbohydrates. Theresults showed that the lingual and sublingual glands showed a positive reaction to AB pH 2.5 stainingand PAS with the intensity varied from weak (+) to strong intensity (+++) scattered in the cytoplasm of thecell. In the cytoplasm of cells of the mandibular glands showed negative reaction (-) to the AB pH 2.5staining but reacted positively to PAS with the intensity varied from weak (+) to strong (+++). Based onthe result of the study it can be concluded that lingual and sublingual glands of Water monitor containacidic and neutral carbohydrates while mandibular glands only contain neutral carbohydrates.

The data available on the female reproductive organ of mouse deer (Tragulus javanicus) is still very limited. A study was therefore conducted to investigate the distribution and the concentration of carbohydrate residues during the development of ovary follicles. An ovary at luteal phase was used in this study. Thin sections of the ovary were prepared occording to the standard methods and they were then histochemically stained with flourecnece-labelled lectins such as peanut agglutinin (PNA), Ricinus communis agglutinin (RCA), Concanavalin A (Con A), Winged bean agglutinin (WGA) and Ulex europaeus agglutinin (UEA). The result showed that changes in the distribution and the concentration of carbohydrate occured during the development of the follicle. During the preantral stage, the cytoplasm of oosit contained carbohydrate with the residues of glucosa dan mannosa. Zona pelusida contained carbohydrates with residues of glucosa, mannosa, galactosa dan N-asetylgalactosamine, whereas extracellular matrix contained carbohydrate with the residues of glucosa dan mannosa. In the antral follicle, the cyitoplasm of oocytes contained carbohydarte with the residues of galactosa dan N-asetylgalactosamine, whereas its zona pelusida, extracellular matrix and follicular fluid contained carbohydarte with the residues of fucosa, N-asetylglucosamin and cyalic acid. Diffrences in the types and the distribution pattern of carbohydrates were observed in this study, both in preantral and antral follicles.
