Abstract

Trimethyltin chloride (TMT) is an organotin compound which neurotoxic at limbus system and hippocampus in human and animal. Pathology changes that caused by the induction of TMT is a neurodegenerative disorder such as nerve cell death and cognitive impairment. This study was aimed to observe brain pathology induced by TMT with multiple doses for 14, 21 and 28 days after treatment. Twenty seven of Wistar rats, at 2 months of age with weight ranging between 200-300 grams were used and divided randomly into 3 groups (n=9). Group I were injected by trimetyiltin with a dose of 6 mg / kg, group II were injected bytrimetyltin with a dose of 8 mg / kg and group III as control without injection. Observation of brain pathology was done by euthanasia on day 14, 21 and 28 after treatment, three rats each. Cortex and hippocampus of the brainwere observed using Hematoxilin and Eosin staining (HE). All of the research procedure was done with the approval and supervision of Animal Ethics Committee LPPT UGM No. 300/KEC-LPPT/VII/2015. The observation of histopathology of the brains neuron cells injected by trimetyltin dose of 6 mg/kg and 8 mg/kg body weight was showed increasing cell death of brain neurons in the cortex and hippocampus compared to the control group. The highest cell death was on day 14 in the hippocampus and cortex cerebral on day 21after TMT injection. The neuron cell death characterized by the shrink of brain neurons as well as colored eosinophilic cytoplasm. One way ANOVA statistical analysis showed a significant difference number of neurons cell deathbetween control and treatment groups. Based on this research, it can be concluded that the trimetyltin injection dose of 6 mg / kg and 8 mg / kg of body weight caused neuron cell death in the brain rats from fourteen day aftertreatment, especially in the hippocampus and cortex.

Abstract

Aeromonas hydrophila causes a disease that often infects fish and is known as Motile Aeromonas Septicaemia (MAS), Hemorrhagi Septisemia, Ulcer disease or Red-Sore disease. The   aims of this study were to develop polyclonal antibody of  Aeromonas hydrophila in the rabbits to   confirm the diagnosis of Aeromonas hydrophila  in the fish by immunohistochemistry staining method. Preparation of polyclonal antibodies was performed on the rabbits used to Aeromonas hydrophila bacteria that have been tested biochemically by intravenous and intraperitoneal injection. Doses of Aeromonas hydrophila  bacteria were 109 CPU/ml  of 0.5 ml at first injection, 1 ml at second injection, 2 ml at thirth injection and 3 ml at fourth injection. Blood serum collection was performed at week 5 after injection from  an  ear and intracardial vein. The result of antibody titer was 28 = 1024 which measured by   tube test. Furthermore, polyclonal   antibody was used to immunohistochemistry  staining with 400x dilution. The results of the staining showed that an immunopositive reaction in the liver, skin,lien,  gill, kidney, and heart of fish to Aeromonas hydrophila antibody. The research conclution was polyclonal antibody from rabbit can be used to accurately confirm the diagnosis of Aeromonas hydrophila  based on antigen and antibody reaction.

Abstract

Red sea bream iridoviral disease (RSIVD) is caused by red sea bream iridovirus (RSIV), adouble stranded DNA of Icosahedral virus with a diameter of 120-240 nm [1]. RSIV is  one  of the  species  of  the Megalocytivirus,  Genus  of  the  Iridoviridae Family,  first reported to infect red sea bream (Pagrus major) fish, at Sikoku Island, Japan 1991, and since then it has been noted to cause considerable economic losses to fisheries in Singapore, Taiwan, Thailand, Korea, Philippines, Malaysia and also in Indonesia [2,3,4]. Rapid transmission with high mortality rates in fish populations infected becomes a serious threat to the aquaculture fishery business. Stained imprints or tissue sections [1], monoclonal antibody technique (MAb), Immunofluorescent Antibody Tests (IFAT) [5], Polymerase Chain Reaction (PCR) [6] Electron Microscope and Multiplex PCR [2] methods have been introduced.  Although it is very effective for detecting RSIVD in infected fish, but requires training and specialized equipment at a high cost.Co-agglutination test is a diagnostic method, used both in humans and animals in detecting bacterial or viral diseases [7], this method is fast, easy to use, and does not require special equipment. Test results from co-agglutination are easily seen macroscopically, so it is suitable if developed in RSIVD detection in the field case. This study aims to create and conduct RSIVD co-agglutination kit field tests supported by molecular studies and diagnostic analysis of the sensitivity and specificity of the accuracy and reliability of the kit. Then the test results will be compared from the pooling and individual samples.
