This research aims to see the histological structure of the crop in poultry. Animals used were chicken (Gallus domesticus), duck (Anser anserdomesticus), and pigeon (Columba domesticus) each group consists of three animals. Crop tissue of each animal were taken and processed inmicrotechnic and stained with Hematoxilin and Eosin (HE), then observed with digital microscope. The results showed that there were thesimilarity of the general structures of crop from the three types of these poultry. which consists of the tunica mucosa, tuni ca submucosa, tunicamuscularis and tunica serosa. Lamina muscularis in duck is more obvious than chicken and pigeon. Mucosal gland of duck shaped oval, chickenshaped rounded, and the pigeons are not found. Tunica muscularis duck arranged longitudinally in the outside dan ci rcular in the inside. Tunicamuscularis duck arranged longitudinally in the inside, and circular in the outside, and tunica muscularis in pigeon just arranged longitudinally.____________________________________________________________________________________________________________________Key words: histological, crop, poultry

One of the diseases that attacks poultry especially laying hens (Gallus gallus domesticus) is colibacillosis, a disease caused by Escherichia coli. E. coli is a bacterium that has opportunistic properties, which is normally present in the digestive tract in a controlled amount, but when the condition of the chicken decreases, it can develop into pathogens. Kidneys are organs that are vulnerable to substances that are toxic and are also susceptible to bacterial infections. This study aimed to determine the histological structure of kidneys of laying hens (Gallus gallus domesticus) who died due to the infection of E. coli. The research was conducted at a Pathology Laboratory (BBVet), Denpasar. The hen’s kidneys were processed with the paraffin method and Hematoxylin-Eosin staining. Cell damage that occurs is observed by using the Image Raster application. The data obtained were analyzed with the scoring method. Renal histopathology parameters can be seen in the form of degeneration, necrosis, congestion, and inflammatory cell infiltration. The results obtained cell damages namely 46% of degeneration, 60% of necrosis, 44% of congestion and 76% of inflammatory cell infiltration.

Purpose: The implantation of a gastric balloon (also known as intragastric balloon) is an established and reversible endoscopic procedure for adiposity therapy. Structural changes of the stomach wall are expected to occur with gastric balloon implantation; however, until now these changes have rarely been investigated. Methods: We compared the histological structure of the stomach wall after gastric-sleeve resection in a group of patients following gastric balloon implantation and a group without previous gastric balloon implantation. Results: Following gastric balloon implantation, the tunica muscularis was found to be significantly thicker than without gastric balloon implantation. The enlarging of the tunica muscularis is not caused by hyperplasia of the leiomyocytes, but by hypertrophy of the leiomyocytes and an increase in collagen fibers (fibrosis). Conclusion: A longer-lasting hypertrophy of the tunica muscularis, particularly in the corpus, should be taken into account when surgical treatment follows gastric balloon implantation. The staple suture height should be adjusted to the altered tissue composition since reduced tissue elasticity must be expected due to fibrosis.

This research aimed to study the histology of the digestive system of the watersnake (Enhydris enhydris). The digestive system taken was the esophagus, stomach, frontal small intestine and the back of the large intestine from three watersnakes. The samples were then made into histological preparations with hematoxylin-eosin (HE) staining and observed exploratively. The results showed that the digestive system of the watersnake was composed of layers of tissue, namely the mucosa, tunica submucosa, tunica muscularis, and serous tunica. Mucosal mucosa consisted of the lamina epithelium, lamina propria, and mucous lamina muscularis. The submucosal tunica consisted of connective tissue with blood vessels, lymph, and nerves. The muscular tunica was composed of circular muscles and elongated muscles. The serous tunica consisted of a thin layer of connective tissue that was covered by a thin layer of the mesothelium (mesothelium). The histological structure of the snake digestive system is not much different from the reptile digestive system. However, in the small intestine of the snake, Brunner, and liberkhun glands are not found. Lamina epithelial in the small intestine of the snake is composed of the layered cylindrical epithelium.

Abstract The avian alimentary tract has evolved into different histologic structures to accommodate the physical and chemical features of several food types and flight requirements. We compared the esophagus, proventriculus, and gizzard of the domestic fowl, Gallus gallus domesticus (GGD) and kestrels, Falco tinnunculus (FT) using immunohistochemistry and scanning electron microscopy with various stains and lectins [Dolichos biflorus agglutinin (DBA) and Ricinus communis agglutinin I (RCA120)], and α-smooth muscle actin (α-SMA). The esophagus of GGD demonstrated thickened epithelium, muscularis mucosae, and inner circular longitudinal tunica muscularis layers; moderate outer longitudinal tunica muscularis layers; and a true crop. In contrast, the esophagus of FT showed a thin epithelium, no muscularis mucosae, moderate inner longitudinal and thick outer circular tunica muscularis layers, and no true crop. In the proventriculus, the nature of the secretion in GGD was neutral, but that of FT was acidic and neutral. In the gizzard, the muscle coat of GGD by α-SMA had no muscularis mucosae, unlike FT, which had muscularis mucosae. In summary, there are many histologic differences between GGD and FT to meet their different physiologic needs, such as feeding.

Otoconia are microscopic geometric structures that cover the sensory epithelia of the utricle and saccule (gravitational receptors) of mammals, and the lagena macula of birds. The importance of otoconia for maintanance of the body balance is evidenced by the abnormal behavior of species with genetic defects of otolith. Although a few reports have dealt with otoconia formation, some basic questions remain unanswered. The chick embryo is desirable for studying otoconial formation because its inner ear structures are easily accessible, and its gestational period is short (21 days of incubation).The results described here are part of an intensive study intended to examine the morphogenesis of the otoconia in the chick embryo (Gallus- domesticus) inner ear. We used chick embryos from the 4th day of incubation until hatching, and examined the specimens with light (LM) and transmission electron microscopy (TEM). The embryos were decapitated, and fixed by immersion with 3% cold glutaraldehyde. The ears and their parts were dissected out under the microscope; no decalcification was used. For LM, the ears were embedded in JB-4 plastic, cut serially at 5 micra and stained with 0.2% toluidine blue and 0.1% basic fuchsin in 25% alcohol.

Otoconia of higher vertebrates are interesting biological crystals that display the diffraction patterns of perfect crystals (e.g., calcite for birds and mammal) when intact, but fail to produce a regular crystallographic pattern when fixed. Image processing of the fixed crystal matrix, which resembles the organic templates of teeth and bone, failed to clarify a paradox of biomineralization described by Mann. Recently, we suggested that inner ear otoconia crystals contain growth plates that run in different directions, and that the arrangement of the plates may contribute to the turning angles seen at the hexagonal faces of the crystals.Using image processing algorithms described earlier, and Fourier Transform function (2FFT) of BioScan Optimas®, we evaluated the patterns in the packing of the otoconia fibrils of newly hatched chicks (Gallus domesticus) inner ears. Animals were fixed in situ by perfusion of 1% phosphotungstic acid (PTA) at room temperature through the left ventricle, after intraperitoneal Nembutal (35mg/Kg) deep anesthesia. Negatives were made with a Hitachi H-7100 TEM at 50K-400K magnifications. The negatives were then placed on a light box, where images were filtered and transferred to a 35 mm camera as described.
