Abstract

Dog is man's favorite companion animal and they are also beneficial as an animal model in biomedical research. So far, the Indonesian native dog's physiological values for diagnostic or research purposes, was based on literature which differed in breeds, geography and age variety. Furthermore, there is little publication on Indonesian native's dog physiological value which emphasize on its age variety, specially its comparative study between adult and puppies. Comparative parameters which were used in this study were heart rate {HR), respiratory rate {RR), non-invasive blood pressure {NIBP) and rectal temperature {RT). The study utilized fifteen Indonesian native dogs. The result showed a significant {p< 0.05) higher HR's values on puppies to adult, which are 152.50±14.76 and 95.93±23.7 beat per minute), respectively, while the RT's were lower on puppies to adults {37.53±0.29 and 38.23±0.73 °C, respectively). The NIBP's values were significantly lower on puppies to adult, which are systole {83.93±13.29 Vs 129.68±24.45 mmHg), diastole {37.50±16.31 Vs 72.96±20.33 mmHg) and mean blood pressure values {58.21±13.30 Vs 91.82±24.34 mmHg). The insignificant result was found on RR values which are 26.50±7.93 and 28.21±14.34 for puppies and adult, respectively. The main reason for the differences in above parameters among puppies and adult can be defined by their metabolic rate and growth process.

Abstract

Uric acid concentration could be determined by spectrophotometry method. Uric acid was oxidized into allatonin in the presence of uricase and calculated by measuring the decrease of uric acid absorbance at 293 nm. These uricase were obtained from cells of Lactobacillus plantarum. L. plantarum K. Mar. E was isolated from passion fruit skin and L. plantarum Mgs. Psmb and Mgs. Bst from mangosteen. This research was conducted to observe the activity and kinetics of uricase from various cells of L. plantarum by spectrophotometric method. The plate assay method indicated that L. plantarum produced uricase, based on the clear zone about 0,2 mm on glucose yeast peptone medium contained 0,2% uric acid. The optimum condition of uricase activity from the three different sources occured in physiological condition. Uricase activity generated from cells of L. p/antarum K. Mar. E, Mgs. Psmb, and Mgs. Bst were 0,1073; 0,0867; and 0,0842 U/ml, respectively. The kinetic parameters for uricase, determined with uric acid as the substrate. Vmax produced by L. plantarum K. Mar. E, Mgs. Psmb, and Mgs. Bst were 1,3635; 0,0316; and 0,0418 U/ml of bacterial culture, respectively and KM 0,1541; 0,0061; and0,0054 mM, respectively. Uricase activity in various bacterial cells of L. plantarum was stable until the second day.

Abstract

The purpose of the research was to investigate the effects of PEG 400 addition on the characteristics of bioplastic polyhydroxyalkanoates (PHA). PHA was obtained by cultivating Ralstonia eutropha on hydrolysed sago starch substrate using fed batch method for approximately 96 hours. The biomass concentration obtained was 4 g/L with PHA yield 20-30% of dry cell weight. The bioplastic was formed with solution casting method in which chloroform was used as solvent and PEG 400 was used as plasticizer. The concentrations of PEG 400added were 10, 20, and 30% (w/w), respectively. Bioplastic properties which were tested were tensile strength, elongation to break, density, thermal properties, cristalinity, and functional group. The addition of plastisizer tend to increase tensile strength and elongation to break, but decrease density, cristalinity and melting point. Bioplastic with 30% PEG 400 addition gave the best results. Bioplastic with 30% PEG 400 gave a value of tensile strength of 0.083 MPa; elongation to break of 0.881%; density of 0.7881 g/cm3;  melting point of 158.95 ac; and cristalinity of 44.58%. With these properties, the resulted bioi plastic may be used for surgical strings. Keywords: Bioplastic, Polyhydroxyalkanoates (PHA), Ralstonia eutropha, hidrolysed sago starch, PEG 400

Abstract

Myelocytes blood cell tumor in chicken is a disease caused by retrovirus, avian leukosis virus subgroup J (ALV-J). The virus has the same group as human retrovirus (HIV) which caused AIDS, but the avian type possesses oncogenic properties, that could induce cell transformation and tumor formation. ALV-J stimulates the bone marrow's myelocytes and transforms them into tumor cell myelocytoma. The tumor cells then metastasis through the circulatory system causing myeloid leukosis and tumor cells accumulation in various internal organs or myelocytomatosis. This study was done on the base of the leukosis behavior of the tumor. The finding of the metastasis tumor cell in the blood smear examination is thought could be use as the diagnostic clue of the disease. Blood smear from sick chickens are collected and stained with some chemical staining substance such as may grunwald-giemsa, hematoxyllin eosin, periodic acid Schiff, congo red, toluidine blue, and sudan black B. Cytochemistry character of the blood cells was observed using light microscope. The result showed that myelocytes granules were best observed using hematoxyllin eosin, periodic acid Schiff, congo red and toluidine blue while may grunwald-giemsa, and sudan black B could not differentiate the granules. By this method, the field veterinarian will able to screen the suspected chicken flock for myeloid leukosis earlier than the occurrence of tumor formation.

Abstract

Population of bulls in the world is decreasing to 80%. On Java and Bali, the habitat of the species has declined by about 20% and 30% respectively (IUCN 2003). In Java, especially in Alas Purwo National Park, the decreasing population of bulls is caused by hunting and degradation of habitat. The estimation of growth bulls population in APNP is increase. The size of population in the beginning is 588 individuals the rate of growth is 0.093 and carrying capacity of habitat is 4772 individuals. The population will reach the carrying capacity by the year of 2126. The pattern of spatial distribution of bulls in APNP based on analysis of chi-square test is grouped (l2hit>l220.025). The pattern of distribution in low-land forest and platation forest is randomized (l20.975£l2hit£l20.025), meanwhile it is grouped in coastal forest ecosystem. The pattern of distribution in each type of ecoystem is influenced by the factor of resources (feedings, water, and salty water) and predation factor.
