 หัวเรื่อง:การศึกษาโรคเฮกซามิต้าในลำไส้ของปลาปอมปาดัวร์ ผู้เขียน: ดร.องอาจ เลาหวินิจ, รองศาสตราจารย์ ,  Kiti Srisuparb, Nongnuch Jantaraj, สุปราณี ชินบุตร สื่อสิ่งพิมพ์:pdf AbstractThe occurrence of Hexamita disease, intestinal parasitic infection, in Discus, Symphysodon aequifasciata were collected from a farm in Bangkok and studied from January to December, 1991. The incidence of this disease showed high percentage in July. Histopathological examination of the examined fish revealed inflammation of the intestine, enteritis and leucocytes proliferation. Many parasites were found in the inflamed area. There was no parasite and pathological changes were found in liver, kidney, spleen, and stomach of examined fish. Four chemotherapeutic agents were used for treatment of the infested fish. It was found that the Metronidazole at a concentration of 10,000 ppm gave more effective in eliminating the parasites than Furazolidone, Copper sulphate and Magnesium sulphate, at concentrations of 75 ppm, 1 ppm and 3 percent in feed respectively. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Histopathological Changes in Sea Bass, Lates calcarifer Exposed to Water Soluble Fraction of Light Arabian Crude Oil ) ผู้เขียน:ดร.ชลอ ลิ้มสุวรรณ, รองศาสตราจารย์ , Suchitra Shownpreecha, สุปราณี ชินบุตร, Sirichai Dharmvanij สื่อสิ่งพิมพ์:pdf AbstractHistopathological changes in sea bass, Lates calucarifer continuously exposed to water soluble fraction (WSF.) of light Arabian crude oil at the concentrations of 0.11, 0.23 and 0.46 mg/l for 8 reeks were studied. Edema, hyperplasia and telangiecstasis of secondary lamellae were the common lesions observed in gills of sea bass exposed to all concentrations of WSE. of crude oil. There was a substantial increased in the number of mucous cells in the olfactory mucosa along the periphery of the olfactory lamellae at the highest concentrations of WSF. Fatty degeneration was commonly found in the livers and the severity was correlated to the concentrations and the exposure times to WSF. Of crude oil. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Histopathological Observation on Experimental Aeromonas hydrophila Injection in Clarias batrachus ( Linn. )) ผู้เขียน:สุปราณี ชินบุตร, Pikul Jiravanichprisal สื่อสิ่งพิมพ์:pdf AbstractOne hundred healthy walking catfish were experimentally injected intramuscularly with 0.1 ml. of normal saline ( 0.85 % NaCl ) containing 2.56 x 108 cells of Aeromonas hydrophila. Histopathological changes of skin, muscle, gills and internal organs were studied. Histopathological observations indicated that the gills and the internal organs appeared normal, whereas inflammatory responses of skeletal muscle of the early stage was detected. It was characterized by diapedesis of blood vessels in the hypodermal layer, hydropic degeneration of muscle fibres and myoseptum. Advanced stage was characterized by the appearance of dead cells of epidermis, dermis and hypodermis and formation of ulcerative lesions on the body surface. The natural healing process was observed and characterized by the migration of epithelial cells of epithelial cells to cover the lesion. In addition, fibrosis and granulation were observed by day 4. The lesion was completely healed within 3 weeks after the bacterial injection. |

หัวเรื่อง:พยาธิวิทยาของปลาดุกด้านที่ขาดกรดแพนโทเธนิค ผู้เขียน:ดร.ชลอ ลิ้มสุวรรณ, รองศาสตราจารย์, Nanthawat Kirdchuen, สุปราณี ชินบุตร สื่อสิ่งพิมพ์:pdf AbstractWalking catfish (Clarias batrachus) fingerlings fed purified diet devoid of pantothenic acid showed reduced appetite at the end of the 4th week and reduced growth at the end of the 9-week feeding. Average mortality rate for the fish fed pantothenic acid – deficient diet was 80%. Mortalities first occurred during the 5th week. At the beginning of 5th week the fish fed the pantothenic acid-free diet showed eroded barbells and fins. Moribund fish fed vitamin-free diet at the 12th week showed hemorrhagic areas on the skin and Aeromonas hydrophila was isolated from liver and kidney. Histopathologically, epidermal necrosis of the barbells was observed on fish fed pantothenic acid-free diet at 5th week. However, clubbed gills was found at the 12th week. Lesions were also observed in skin, liver and spleen of moribund fish fed vitamin – free diet accompanied by A. hydrophila infection at 12 weeks. |
หัวเรื่อง:การศึกษาการเกิดของอวัยวะและลักษณะทางเนื้อเยื่อของปลากัดวัยอ่อน Belta splendens Regan ผู้เขียน:สุปราณี ชินบุตร, Pornlerd Chanrat, Nongnuch Laohavisuti สื่อสิ่งพิมพ์:pdf AbstractA study on organogenesis and histology of Fighting fish fry was conducted. The fry developed to fingerling size within 15 days after hatching. The development and formation of the organs of Siamese fighting fish fry from day 1 to day 30 are described. Yolk sac was reabsorbed within day 4 after hatching. The nervous system including the brain, ears, spinal cord ect, was well developed in comparison to the other systems of the fry at same age. It was almost completely developed into different parts when the fry was 2 days old. The heart of 1-day fry was the blood chamber and it developed into the complete four chambers at the age of 8 days. The digestive tract was developed as a long blind tube from day one and became fully formed as the one in adult around day 15. Exocrine pancreas and spleen were forming by day 3 and 5, respectively. The skeletal muscle blocks were separated from each other by the myoseptum. They quickly expanded in volume. Thyroid gland and thymus gland were observed around day 7 and day 8, respectively. The labyrinth organ was found at the anterior area of opercular chamber by day 9. Around day 15, gonads were differentiated into ovary or testes. |
