Pengaruh Pemberian Diazinon 60 Ec Per Oral Terhadap Aktivitas Enzim Kolinesterase Plasma Darah Ttkus Putih (Rattus norvegicus L.)

Abstrak: Paramita, D.K. dan S. Moeljopawiro. 1997. Pengaruh Pemberian Diazinon 60 EC per Oral terhadap Aktivitas Enzim Kolinesterase Plasma Darah Tikus Putih (Rattus norvegicus L.). Biologi, 2 (3): 115-128. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian diazinon pada tikus putih (Rattus norvegicus L.) terhadap aktivitas enziin kolinesterase plasma darah. Penelitian ini dibagi dalam tiga tahap dan menggunakan 88 ekor tikus jantan. Tahap pertama menggunakan 58 ekor untuk uji orientasi yang bertujuan untuk mengetahui apakah kisaran LD50 yang telah didapatkan pada penelitian sebelumnya dapat diterapkan pada uji pendahuluan. Tahap kedua uji pendahuluan yang bertujuan untuk menentukan dosis perlakuan pada uji perlakuan dan ketiga tahap perlakuan. Pada uji perlakuan digunakan 30 ekor tikus jantan yang dibagi menjadi 6 kelompok. Masing-masing kelompok terdiri dari 5 ekor tikus. KelompokA sebagai kelompok kontrol, tidak diberi perlakuan. Kelompok B diberi aquades sebanyak 2 ml. Kelompok C, D, E, F, masing-masing diberi perlakuan diazinon dengan dosis 150 mg/kg bb, 200 mg/kg bb, 250 mg/kg bb, dan 300 mg/kg bb. Setelah diberi perlakuan, setiap jam selama 5 jam pertama aktivitas enzim kolinesterase diperiksa. Aktivitas enzim kolinesterase diperiksa dengan metode S-Butyrylthiocholine iodie. Hasil yang diperoleh dianalisis dengan analisis varian faktor A (perlakuan) mixed B (waktu setelah perlakuan), dan dilanjutkan dengan uji LSD dengan taraf kepercayaan 95%. Hasil penelitian ini menunjukkan bahwa diazinon dapat menghambat aktivitas enzim kolinesterase plasma. Pemberian diazinon mulai dosis 150 mg/kg bb sampai dengan 300 mg/kg bb dengan interval kenaikan 50 mg/kg bb tidak menunjukkan beda nyata. Penghambatan enzim maksimal terjadi pada jam pertama setelah pemberian diazinon pada semua kelompok (C, D, E, dan F) yaitu masing-masing sebesar 56,80%, 54,15%, 58,50%, dan 60,00%. Dengan ini dapat dikatakan bahwa diazinon mulai dosis 150 mg/kg bb telah dapat menghambat aktivitas enzim kolinesterase plasma. Kata kunci: toksikologi, diazinon, aktifitas enzim, kolinesteras

Effect of earthworm (Lumbricus rubellus) in feed Formulation to Improve Fatty Acids Profile in eel (Anguilla bicolor) Meat

Eel requires unsaturated fatty acids of linolenic acid for growth. Which can be supplied from earthworms. In this study, addition of earthworm in formulation feed aimsed to improve the fatty acid profile eel meat. This research used experimental method and randomized complete design method with five treatments. Each treatment was repeated four times. The use of earthworms in feeding treatment formulation was done for 21 days with different level i.e: 0 % (P0), 25 % (P1), 50 % (P2), 75 % (P3) and 100 % (P4). The result showed that the addition of eartworm significantly influenced the omega 3 contents (EPA & DHA) of eel meat

Native early antigen of Epstein-Barr virus, a promising antigen for diagnosis of nasopharyngeal carcinoma

The Epstein-Barr virus (EBV) early antigen (EA) complex consists of multiple proteins with relevance for diagnosis of acute, chronic and malignant EBV related diseases, including nasopharyngeal carcinoma (NPC). In a recent study, it was found that the molecular diversity of EBV-specific IgG and IgA antibody responses in NPC patients and demonstrated that these reflect independent B-cell triggering leading to distinct EBV antigen-recognition profiles. The fine-specificity of NPC-related IgG and IgA responses was explored further against defined recombinant and synthetic EBV-EA antigens using immunofluorescence, immunoblot and ELISA techniques and determined their diagnostic value in a large panel of sera from NPC (n = 154), non-NPC tumor patients (n = 133), acute mononucleosis patients (n = 70) and healthy EBV carriers (n = 259). Individual recombinant EBV-EA markers yielded sensitivity/specificity values not exceeding 86%, whereas selected EA-specific peptide epitopes were rather poorly recognized by IgG and IgA antibodies in NPC sera. Surprisingly, we found that a "low salt" native EA-protein extract reproducibly prepared from purified nuclei of EA-induced HH514 cells, and containing characteristic EA(D)-polypeptides, such as p47-54 (BMRF1), p138 (BALF2), p55-DNAse (BGLF5), and p65-TK (BXLF1), but without viral capsid (VCA) or nuclear antigen (EBNA) reactivity, gave highest sensitivity (90.4%) and specificity (95.5%) values for NPC diagnosis in both IgG and IgA ELISA. The data support further the notion that EBV-EA reactive IgG and IgA antibodies in NPC patients are directed against distinct conformational and-in part-linear epitopes on EBV-specific proteins, barely recognized in other EBV-related syndromes. The use of a defined native EBV EA-specific antigen opens the way to further improve serological diagnosis of NPC

Noninvasive diagnosis of nasopharyngeal carcinoma: nasopharyngeal brushings reveal high Epstein-Barr virus DNA load and carcinoma-specific viral BARF1 mRNA

Nasopharyngeal carcinoma (NPC) is the most prevalent ENT-tumour in Indonesia. We investigated the primary diagnostic value of Epstein-Barr virus (EBV) DNA load and mRNA detection in noninvasive nasopharyngeal (NP) brushings, obtained prospectively from consecutive Indonesian ENT-patients with suspected NPC (N=106) and controls. A subsequent routine NP biopsy was taken for pathological examination and EBER-RISH, yielding 85 confirmed NPC and 21 non-NPC tumour patients. EBV DNA and human DNA load were quantified by real-time PCR. NP brushings from NPC patients contained extremely high EBV DNA loads compared to the 88 non-NPC controls (p <0.0001). Using mean EBV DNA load in controls plus 3 SD as cut-off value, specificity, sensitivity, positive and negative predictive values were 98, 90, 97 and 91%, respectively. Epstein-Barr nuclear antigen 1 (EBNA1) and the carcinoma-specific BARF1 mRNA were detected by nucleic acid sequence based amplification and found in 86 and 74% of NP brushings, confirming NPC tumour cell presence. EBV RNA positivity was even higher in fresh samples stored at -80 degrees C until RNA expression analyses (88% for both EBNA1 and BARF1). EBV RNA-negative NP brushings from proven NPC cases had the lowest EBV DNA loads, indicating erroneous sampling. No EBV mRNA was detected in NP brushings from healthy donors and non-NPC patients. In conclusion, EBV DNA load measurement combined with detection of BARF1 mRNA in simple NP brushings allows noninvasive NPC diagnosis. It reflects carcinoma-specific EBV involvement at the anatomical site of tumour development and reduces the need for invasive biopsies. This procedure may be useful for confirmatory diagnosis in large serological NPC screening programs and has potential as prognostic too
