Fluoroquinolones changes in the articular cartilage especially with high doses and more than two weeks use. Due to relatively excessive use of enrofloxacin in the sheep flocks, this study was done to investigate the effects of enrofloxacin on some changes in growing lamb articular cartilage to evaluate some possible mechanisms involved these changes. Twelve ,2 month – old male lambs divided in three groups: control group received only normal saline; therapeutic group received 5mg/kg enrofloxacin subcutaneously, daily, for 15 days and toxic group received 35 mg/kg enrofloxacin as the same manner as therapeutic group. Twenty four hours after the last dose, the animals were slaughtered and their stifle joints were dissected. After gross examine, sampling were done quickly for further microscopic studies. Histological sections were evaluated morphometrically and histochemically. Macroscopic changes such as cartilage flaps were seen only in toxic group. Microscopic changes were included the presence of spindle – shaped cells and cavitation in matrix, decreases of total cartilage thickness and chondrocyte numbers, increases of empty lacunae numbers, decreases of matrix proteoglycans and carbohydrates. Some of these changes were observed in therapeutic group with less intensity in comparison to toxic group. Results of this study showed enrofloxacin use in growing lambs even at recommended therapeutic dose, is not completely safe on articular cartilage. Manuscript profile

In the fish, intestine has different length according to the type of die. Since Barbusgrypus has an omnivorous diet which it’s the abundant and native fish in Khuzestan. Intestinal structures in these fishes are different from diet of carnivorous. Recognition histology of the intestine in this fish can help to feed and nutritional requirement for the development of upbringing of this fish.In this study, 10 Shirbot with average weight 354.25±60.52 g and mean length of 36.25±4.16cm was chosen and after the easy drawing, the intestine are removed and the section of paraffin embedding and stained by routine histological was done about it. With Dino lite lenses and Dino capture software various parts was measured and then data were analyzedwith SPSS software and with p Manuscript profile

Argyrosomidae family and the species Argyrosomus hololepidotus due to high valued protein are among the most valuable aquatics in the Persian Gulf, Oman Sea and the coasts of Khuzestan. Lymphoid tissues are of the most important tissues in fish which their identification is important in health and disease states. Unlike mammals, fish lack lymph node and also there is not hematopoietic tissue in their bone marrows, and so mainly Hematopoiesis is done in their spleen and kidney. In this study, 6 pieces of Argyrosomus hololepidotus were provided from the Persian Gulf. Some samples from the spleen up to 5mm thickness were prepared and fixed in 10% buffered formalin. Then tissue sections were prepared in 5-6 μ and after HandE staining, the structures of the capsule and parenchyma of pronephrose were studied histologically. In order to confirm the results and findings of this staining, silver staining was also used. Microscopic results showed that tissue structure of Argyrosomus hololepidotuspronephrose was consisted of hematopoietic tissue, lymphoid tissues and kidney tubules. Pronephrose lymphoid tissues are also consisted of reticular supportive tissue and lymphocytic parenchyma cells. Manuscript profile
