Abstract

Avian influenza virus subtype H5N1 (AIV H5N1) is highly pathogenic and fatal in poultry. The virusis still endemic with low virulence rate, although it may play a critical role in causing high morbidity andmortality rates in poultry in Indonesia. In general, diagnostic approach for AIV H5N1 is based onconventional serological and viral isolation methods that have the potential to produce consumings oftime and relatively expensive cost within the laboratory without compromising test utility. Thus, amolecular approach of multiplex reverse transcription-polymerase chain reaction (mRT-PCR) was developedand applied for the detection of matrix gene type A influenza viruses, AIV subtype subtype H5hemagglutinin gene with simultaneous detection of N1 nucleoprotein gene. Thirty sera specimens fromthe diseased commercial chickens that were specifically amplified positive-RT-PCR for AIV H5N1 wereselected for mRT-PCR. The mRT-PCR products were visualized by agarose gel electrophoresis and consistedof DNA fragments of AIV of 245 bp, 545 bp and 343 bp for M, H5 and N1 genes, respectively. Thus, themRT-PCR that can rapidly differentiate simultaneously between these genes is very important for thecontrol and even eradication of AIV transmission in poultry in Indonesia.

Abstract

Calcitriol supplementation in ovariohisterectomized rat was known to decreased calcium retention.The objective of the research was to study the response of femur bone to calcitriol supplementation for 30weeks in ovariohisterectomized rats consuming casein. Twenty female Wistar rats at 8 weeks of age wererandomly divided into four groups (unovariohisterectomy without calcitriol supplementation (N),unovariohisterectomy with calcitriol supplementation (ND), ovariohisterectomy without calcitriolsupplementation (O) and ovariohisterectomy with calcitriol supplementation (OD) of five each. Thirtyweeks after surgery, femur was taken for histopathological and immunohistochemistry examination.Immunohistochemistry of distal femur metaphysis in group O and OD were revealed decreasing tartrateresistant alkaline phosphatase 5b (TRAP5b) in trabecular bone, which was located in bone marrow space,and also in trabecular speculum surface. Histopathological analysis of distal femur metaphysis in groupN and ND were showed normal structure, meanwhile, distal femur metaphysis in group O and OD wereshown some abonormalities, such as increased of bone marrow space, domination of adipocytes in the bonemarrow, and decreased of trabecular bone speculum in metaphysis. Based on the results, it was concludedthat femur bone of ovariohisterectomized rats fed casein with and without calcitriol 8ng/daysupplementation for 30 weeks were showed unbalanced between resorption and formation of bone whichwas domination by bone resorption.
