Abstract

Paraquat dichloride has been used by farmers as a herbicide to kill the grass. On the other hand, paraquatdichloride is harmful if enters to the body, causing Parkinson’s disease, since it is disrupting dopamineproduction in the substantia nigra pars compacta or dopamine pathways Nigro striatal pathway. The studywas done to fi nd out the histological changes of catecholaminergic neurons and Nigro striatal pathway causedby paraquat dichloride treatment in Wistar rats as a model of Parkinson’s disease.Twenty-two Wistar rats 3,5 months old were divided into 4 groups, 5 rats each. Group I (control group)were injected with aquabidest, while groups II, III, and IV were injected intraperitoneally with paraquatdichloride in aquabidest, with the dosage 5 , 10 and 15 mg/kg bw respectively. The rats were injected onceper week for 6 weeks. Three days after the last injection, the rats were anesthetized using xylasin (2 mg/kg)and ketamine (20 mg/kg) intramuscularly, and then were intracardiac perfused using physiological saline asprerinse solution, followed by 10% buffered formalin solution as a fi xative. After animals were fi xed, the brainswere removed and embedded in paraffi n block and cut in 12 μm thickness for immunohistochemistry stainingusing tyrosine hydroxylase antibody. The results of staining then were observed under light microscope andanalyzed descriptively.The results showed that the catecholaminergic neurons were distributed in the substantia nigrapars compacta in all treatment groups, however, the cell density were found decreased only in group IV.Catecholaminergic neurons appear in the bipolar and multipolar form, while dopamine ‘Nigro striatal pathway’was found exist in all treatment groups. From our study, histologycally the decreased of catecholaminergicneurons is only found in rats that received paraquat dichloride in dose 15 mg/kg bw for 6 weeks.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian rumput laut terhadap kualitas sperma tikes akibat pencemaran timah hitam. Dalam penelitian ini digunakan 12 ekor tikus putib jantan dewasa, dibagi secara acak menjadi 4 kelompok masing-masing 3 ekor. Kelompok I, tikus-tikus hanya diberi akuades secara oral. Kelompok11,111 dan IV, semua tikus diberi Pb asetat 0,5 g/kg bb secara oral setiap hart selama 120 hart. Kelompok DI dan IV masing-masing disertai dengan pemberian larutan rumput laut dosis 8 g/kg dan 16 g/kg bb secara oral pe, hari selama 120 hart_ Pada akhir penelitian masing-masing films dart semua kelompok dikoleksi spermanya untuk dilakukan pemeriksaan terhadap motilitas, viabilitas dan konsentrasi apermanya. Semua tikus percobaan kemudian dietanasi dan dinekropsi, organ testis diambil dan difiksasi dalam ICJ% formalin untuk preparasi histopatologis. Hasil penelitian memperlihatkan adanya peningkatan motiiitas, kemampuan hidup dan konsentrasi spermatozoa secara sangat signifikan (P

Abstract

The climbing perch (Anabas testudineus) is a freshwater fish that can withstand highly unfavorable environments and stay out of the water for extended periods. Its anatomical characteristics showed terrestrial adaptation and terrestrial locomotion properties enable the use of climbing perch as an animal model. Moreover, its bone and cartilage profiles at different stages are crucial to improving the anatomical information for the osteogenesis model candidate. The current study aimed to illustrate the skeletal profiles of juvenile and adult climbing perch with the whole staining method. The samples included two adults and two juvenile climbing perch from Daerah Istimewa Yogyakarta, Indonesia. The fish were euthanized using β-hydroxyethyl phenyl ether in a lethal dose. The skeleton was examined using the Alcian blue–Alizarin red whole staining, which revealed the bones and cartilage under the stereomicroscope. The result showed that the bone is the main skeleton. Cartilage was detected in the area surrounding the orbit in the adult climbing perch and in the pterotic, pterosphenoid, prootic, and distal end of the hypural, parhypural, and basal pectoral girdle in the juvenile climbing perch. Endochondral osteogenesis was found in juvenile to adult climbing perch.
