SeNPs were encapsulated in starch as a natural stabilizer and a size-controlling agent The prepared SeNPs were characterized using different techniques. Blood and brain samples were collected from all rats and processed for biochemical, histopathological, and immunohistochemical investigations. In this study, we tested this hypothesis using 40 adult male albino rats that were randomly assigned into four groups (n = 10 per group): group I rats served as the untreated negative controls and were fed with standard diet and distilled water group II rats were orally treated with melamine (300 mg/kg body weight/d) group III rats orally received melamine (300 mg/kg body weight/d) and SeNPs (2 mg/kg body weight/d) and group IV rats received SeNPs only (2 mg/kg body weight/d) for 28 days. The biocompatibility, bioavailability, lower toxicity, and the large surface area of nanosized selenium relative to its other forms indicate that selenium nanoparticles (SeNPs) have a potential ameliorative effect against melamine-induced neurotoxicity. Melamine is a chemical substance used as a food adulterant because of its high nitrogen content it is known to induce neurotoxicity, thereby adversely affecting the central nervous system. He current study targeted to compare between the pancreas (exocrine part) of Japanese quail and Cattle egret. (pH1) and aldehyde fuchsin stains but the interlobular duct of the Japanese quail was negatively reacted. Histochemically, the interlobular duct of the Cattle egret positively reacted to alcian blue Under electron microscopy, the acinar cells were of two types, electron-dense, andĮlectron-lucent acinar cells. The intralobular duct in the Cattle egret is characterized by the presence of Similar in both birds with minor differences. The Exocrine portionĬonsists of serous acini and intercalated duct, intralobular duct, interlobular duct, and main duct. Of dorsal, ventral, third, and splenic lobes, while in Cattle egret the pancreas is not lobulated.
The pancreas of the Japanese quail composed In both birds, the pancreas is located on the right side of theĪbdomen between the ascending and descending loops of the duodenum.
Histochemical, and ultrastructure studies were carried out. Pancreas was investigated in eight apparent healthy mature female Japanese quail and eight Cattle egret. They sometimes take mammals, and there are records of occasional amphibians, lizards and large insects.The current study targeted to compare between the pancreas (exocrine part) of Japanese quail and Cattle egret. This generalist diet allows peregrines to exist wherever there are good mixed bird populations. The larger females take larger prey than males. Little of the kill is wasted - usually all that is left are the intestines and the breastbone with the feathered wings.įeral pigeons are favourite prey wherever they are freely available, though a wide range of birds are taken, ranging in size from goldcrest to woodpigeon. Sometimes, if a surprise attack is possible at lower speeds, it snatches prey from a perch or the ground. Despite its speed and agility, the peregrine is not always successful – many stoops fail to secure prey. The high-speed stoop means that the peregrine must catch its prey on the wing to avoid injuring itself on impact. To enable the bird to breathe at this speed, it has special baffles in its nostrils, which control breathing. It spots the prey at distance and, once positioned correctly, it stoops at speeds of up to 180 kph for the catch. The peregrine feeds primarily on birds, which it catches in flight.
