Abstract

Previous studies shown that Indonesian Thin-Tailed (ITT) sheep are more resistant to infection than Merino sheep infected with Fasciola gigantica. Eosinophils isolated from ITT sheep between 2-6 weeks postinfection could effectively kill immature parasites in vitro by superoxide radicals produced by these cells. The present study was undertaken to identify immunological mechanisms associated with such resistance by comparison of immue responses to fluke antigen in ITT and Merino sheep, a breed susceptible to infection with F. gigantica. This knowledge will enable the development of targeted control strategies using immunomanipulation such as by vaccination.Two critical observations from this in vivo studies were made including (1) eosinophils were significantly elevated at the time of F. gigantica parasite killing in the ITT host relative to the F. giganfi'ca-susceptible Merino host, (2) IgG, responses correlated with resistance to infection in the ITT host.

Abstract

D.D. SASTRAATMADJA, 1987. Testing of rice meal inoculum in the fields Suppl.Berita Biologi 3:1-5.With the aim of testing and using of inoculum by users, studies of the using of inoculum rice powder for oncom production have been carried out.The experiment utilized different kinds of inoculum which contained some strains of Neurospora spp., Mucor spp.,and Rhizopus spp.have been done at several places of oncom producers in Bandung and Bogor.The quality of products were evaluated by analyzing of organoleptic test, texture and growth of mold comparing with local oncom. The results obtained in the experimentshowed that product made by using one strain of Neurospora spp., more liked moderately and having good mold growth, finely conpact and soft texture comparing with the other products and local red oncom in Bandung and Bogor.Besides that all of the strains of Mucur spp., produced good quality of oncom comparing with local black oncom.But all of the strains of Rhizopus spp., did not capable making good quality cf oncom. About the utilizingof powder inoculum by users in general must be fuether more investigated.

Abstract

Study on the fish rearing of the grouper (Serranidae) as well as barramundi cod grouper - C. altivelis (Valenciennes, 1828) and green grouper - E.coioides (Hamilton, 1822) in floating net cages was carried out from June to December 2004 at the coastal waters of Kodek Bay, Malaka Village, Pemenang District West Nusa Tenggara. This paper discussed the results of both grouper fishes grown in Floating Net Cages culture.

Abstract

A quantitative study of epiphytic plants was conducted at the logged over forest in Kiyu, Meratus Mountain, Hulu Sungai Tengah, South Kalimantan. This study used a plot of 10 m x 500 m (± 0,5 ha), and divided into 50 subplot of 10 m x 10 m. The results showed that there were nine species of six genera from three families of epiphytic plants found within the studied plot, with A grostophyllum bicuspidatum as the dominant species. The diversity index (H’) was of 1,85. The diversity of epiphytic plant in these plots was well represented based on the results of analysis of species area curve. Spatial distribution pattern of all epiphytic species was homogeneus, except for A. bicuspidatum. The number of epiphytic host plants observed was 22 individuals from six species of six genera, and five families, with Saurauia nudiflora (Acthiniaceae) was the dominant host plant.

Abstract

Because the flowers of grassos are so reduced, botanists in past have relied mostly on vegetative characters, such as the spikelets and their disposition in the inflorescence,to classify the family.Hackel,in his treatment of the Gramineae in Die Naturlichen pflanzen familien (late 1800'S proposed 12 tribes based on these characteristies and regarded the tribe.

Abstract

Development of high-yielding varieties depends on choice of parents, include per se performance, morphological and agronomic traits, and genetic diversity as determined through geographic origin. Indicators of success can be expected from the value of genetic progress and some other important genetic parameters. The purpose of this study was to calculate the genetic heterogenity, heritability and genetic advances of some quantitative characters of rice genotypes. Experiments were conducted in the district of Kulon Progo, namely: Wates and Panjatan (irrigated condition, dry season of 2012), in Giripeni (rainfed, medium altitude, wet season of 2012/2013), Samigaluh and Kalibawang (rainfed, high altitude, wet season of 2012/2013). Each experiment was designed using a randomized complete block with three replications.Data indicated that not all environmental conditions appropriate for the selection and development of genotype due to low value heritability and expectation genetic advances of each environment was lower than the value heritability and expectation genetic advances for the combined average of the environment. Wates was suitable location for grain yield selection and development in terms of the high heritability values. Kalibawang, Giripeni and Wates have considerable heritabilty value for 1000 grain weight character, hence they can be used as suitable selection locations for these characters.

Abstract

Antiproliferative activity test of octadeca-8,10,12-triynoic acid isolated from parasitic plant Scurrula airopurpurea (Bl.) Dans,against four kinds of human cancer cell lines, i.e: HeLa (human cervix epitheloid carcinoma),leukemia THP1,(human peripheral blood acute monocyte).carcinoma A549 (human lung carcinoma) and lymphoma HUT78 (human cutaneous T-cell lymphoma)was carried out.The results showed that octadeca-8.10,12-triynoic acid exhibits the antiproliterative activity against four kinds of human cancer cell lines with the 1C5I, value of 0.66. 0.86, 0.99 and 2.36 mg/nil for HeLa.leukemia THP1, lung carcinoma A549,and lymphoma HUT78,respectively, lower than 4 mg/ml. which is the antiproliferative activity threshold for pure isolate or compound.

Abstract

Santalum album L. (sandalwood/cendana) is known as one of medicinal and aromatic tree species in Indonesia. The species is valued for its quality light wood timber and for its medicinal properties.The species has been overexploited and is considered as vulnerable plant species.The present study aimed to assess genetic diversity and to estimate genetic relationship among 58 accessions of plant germplasm collection using Random Amplified Polymorphic DNA (RAPD).Two RAPD primers generated 34 scorable bands with 97.06% of them were polymorphic. Clustering analysis was performed based on RAPD profiles using the UPGMA method.The range of genetic dissimilarity value among species was from 6% to 91%, while the range of genetic distance between populations was from 1.89% and 26.88%.These values showed that 5.album from Eastern part of Timor was genetically diverse populations.Within the 12 populations, there were 9 banding patterns recorded from primer OPA 16 and 12 banding patterns from primer OPB 12, suggesting that OPB 12 was more sensitive than that of OPA 16 to show variation within the sample used.
