Abstract

Estrogen is a steroid hormone produced by the ovaries. Estrogen is a hormone that triggers collagensynthesis by fibroblast.Collagen has affects for thickness of dermis.Estrogen deficiency can lead disruptioncollagen synthesis, so has an impact on decline dermis thickness. Unilateral ovariectomy is the act ofremoval of one ovary in the female reproductive system and is a model for estrogen deficiency. Thecondition of estrogen deficiency can be overcome by giving phytoestrogens. Black soybean seed is one ofphytoestrogens source. The purpose of this study was to determine the effect of black soybean extract afterovariectomy on increasing on dermis thickness (Mus musculus L.). The dosage of black soybean ethanolextract used was 0.31 g / ml / day and 0.63 g / ml / day administered orally (gavage) for 20 days. The resultsshowed a dose of 0.31 g / ml / day may and 0.63 g / ml / day increase dermis thickness of mice.

Abstract

This research was carried out to identify the bioactive compounds and sensory characteristics of simplisia extract of frangipani. The kinds of frangipani used in this research were ”Local Bali” frangipani and ”Cendana” frangipani which belong to Plumeria alba, and pink frangipani and ”Sudamala” frangipani which are member of Plumeria rubra. The method used in this research was explorative method to find out the bioactive compounds such as tannin, total phenol, and vitamin C content. The study also observed the sensory characteristics such as flavour, aroma, and colour of simplisia extract of frangipani. The results indicated that the highest tannin content was found in simplisia extract of ”Cendana” frangipani (4.02%), and the lowest tannin content was found in local frangipani (2.32%). The highest total phenol content was found at simplisia extract of ”Sudamala” frangipani (18.94 mg GAE/g) and the lowest content was found at ”Local Bali” frangipani (15.11 mg GAE/g). The highest value of vitamin C was found in ”Cendana” frangipani (2.76 mg/100 g), and the lowest value was found at pink frangifani (1.89 mg/100 g). The panelist preference test indicated that the color of frangipani extract ranged from yellow and brown up to brownies red (color score ranged from 2.66 until 3.97). The score of frangipani extract aroma ranged from 3.58 until 4.07 with criteria of a little specific frangipani smelt until specific frangipani. While, the preference test for flavor indicated that the score of frangipani taste ranged from 3.51 until 4.12 with the criteria of rather astringent and a little sour to astringent.

Abstract

In Indonesia agriculture practice often used the large scale pesticide application such as insecticide, herbicide, and fungicide. The wide use of toxic pesticide has created numerous problem in increasing environtmental hazard to human and to other animals. Many of soil bacteria had important role to degrading chemical compounds into simpler compounds as a bioremediation agent. The aim of this study was to screen the Chlorantraniliprole tolerant bacteria using soil mineral medium with Prevathon pesticide addition, also teo identificate the species of bacteria. This research was conducted at Microbiology Laboratory, Faculty of Mathematics and Natural Sciences, Udayana University. The research was done in three analysis, (1) bacteria test on Prevathon pesticide addition to mineral medium treatment, (2) characterization of bacteria, (3) Identification of pesticide tolerant bacteria with BD BBL Crystal Enteric/Non FermenterID Kit. The results showed that mineral medium with the addition of pesticides Prevathon treatment able to provide a significant different effect on the enrichment stage 1, stage 2 and stage 3 (P<0.05), there was 5 isolates pesticide tolerant bacteria that isolated from Baturiti Tabanan cultivated soil that was BSP 1, BSP 2, BSP 3 known as gram negative bacteria, and BSP 4, BSP 5 known as Gram positive bacteria, pesticide tolerant bacteria identified as Serratia marcescens which is a Gram negative bacteria group and may cause pathogenic.

Abstract

We have reported here a specific human short stature population in Kedurang District, South Bengkulu. AH those are men, described as a mild dwarf (130-150 cm), detected after 5 to 10 years old, caused by the failure on lumbar backbone growth and development, and only found among the men. In this investigation, we examine the inheritance pattern of the dwarfism by using pedigree analysis, study the morphological comparison between the disorder and normal person, and finally we ascertain the variation among the disorder. We accomplished a survey on pedigree family to at least 3-4 generations related to the disorder. The data are then tested with Chi-square test, and transformed to tree families and pedigree analysis. To investigate morphological performance and their variation, we collected morphometric measurements to both disorder and normal group of sample; they are the height, the vertebral bones length, head measurement, the leg and arm length (upper and fore side), and their indexes. The data were analyzed descriptively. To find out the variation, the quantitative expression and penetrance, we evaluated the data according to normal distribution with Z test. The result showed all the dwarfisms in Kedurang are men, who inherited his gene from his carrier mother. As a result, the gene has tightly linked to X chromosome and supposedly belongs to Spondylo Epiphypeseal Dysplasia Tarda (SEDT). These were concluded from 32 related family of dwarfism. We found 19 dwarf persons, grouped into young, adult, and older persons. The their height were shorter than normal (136,5 cm), and the length of vertebrae was under normal value (51,5 cm). Their frontal extremity were shorter than the normal one, but they are in proportion with any part comprised them. Their feet were shorter, but the proportion of leg is longer than calf. The rest is as normally. Among the dwarf person, there are variations of the length. The phenotypic expressivity is varied in the vertebrae, leg, and calf; but the rest is relatively invariable. Their penetrance is strong, mostly in the height, length of vertebrae, and legs. Based on morphological data we concluded that the disorder in the Kedurang, South Bengkulu belongs to SEDT (Spondyloepiphyseal dysplasia tardd).
