Abstract

The research aimed to study whether soil pH affects exogenous application of amino acid tryptophan and IAA in increasing root nodules and soybean yield. The experiment was conducted in greenhouse using 20 cm diameter plastic pot filled with fine soil, arranged in completely randomized design (CRD) with four treatments. Each treatment combination was repeated three times. Three seeds of local soybean variety were planted into each pot then to remain one plant a week after planting. Variables observed were root nodules number, shoot dry weight and seed yield. Plant nutrients were supplied in the form of solution to meet crop needs. The data obtained were analyzed statistically by F test at 5% of level confidence, followed by Duncans multiple range test when there was a significant effect. The results showed that both exogenous amino acid tryptophan and IAA increased number of root nodules, shoot and root dry weight and soybean yield. Higher root nodules number was taken from the treatment combination of 0.001 ppm IAA applied at V3 in Alfisol and Vertisols, and 1.0 ppm on Entisols. However, the highest soybean yields were taken from the treatment combination of 1.0 ppm tryptophan applied at V0 in Alfisols (6.51 g plant-1).Keywords: alfisol, entisol, extra cellular, phyto-hormones, vertisol

Abstract

SARIAktivitas Gunung Salak saat ini mengambil tempat di Kompleks Cikuluwung Putri yang terdiri dari Kawah Ratu, Kawah Hirup, dan Kawah Paeh. Aktivitasnya yang menonjol adalah emisi gas vulkanik dengan komponen utama adalah : H2O, CO2, SO2, H2S, NH3, HCl, H2, N2, dan O2+Ar. Dalam Juli 2007 sejumlah murid sekolah yang sedang berkemah meninggal dunia karena keracunan gas yang secara tiba-tiba meningkat konsentrasinya melampaui ambang batas normal. Berdasarkan penelitian ditemukan bahwa yang menjadi penyebabnya adalah terjadi penurunan kadar air dan kenaikan gas belerang dioksida serta gas karbon dioksida yang tinggi sehingga mencemari udara sekitarnya. Udara yang mengandung racun tersebut kemudian terhirup oleh peserta perkemahan. Karena kawasan ini merupakan area perkemahan, maka pemantauan kimia gas vulkanik mutlak dilakukan secara menerus untuk menghindari jatuhnya korban berikutnya.Kata kunci: Cikuluwung Putri, gas vulkanik, keracunan gas, gas belerang dioksida, gas karbon dioksidaABSTRACTMt. Salak activities are currently located at the Putri Cikuluwung Complex which consists of Ratu Crater, Hirup Crater, and Paeh Crater. The dominant activity is the emission of volcanic gases with the major components consisting of H2O, CO2, SO2, H2S, NH3, HCl, H2, N2, and O2 + Ar. In July 2007 a group ofschool students who were camping died of gas poisoning in a sudden increase its concentration exceeded the normal threshold. Based on the research it is found that the cause is the decline of water levels and the increase in sulfur dioxide gas and carbon dioxide gas is so high that pollute the surrounding air. Aircontaining toxins are then inhaled by the participants of the camp.

Abstract

Visible Light Cure (VLC) is a blue light used in dentistry as an activator for restorative material and fixed orthodontic bonding. The wavelength of VLC is between 400-500 nm and considered non-ionizing radiation that can produce free radicals. According to previous research, the light at wavelength < 500 nm could inhibit cells mitosis, cause cells damage, and reduce cells growth and inflammation. The purpose of this study was to investigate the effect of VLC exposure on gingival epithelial thickness, total neutrophil and macrophage count of gingival connective tissue of Sprague dawley rats. The subjects of this study consisted of 20 Sprague dawley rats, in 2-3 months of age and divided into 4 groups. Each group was 5 rats. The rats in each group were sacrificed before (0 day, as group A) and after 1st (group B), 3rd  (group C), 5th  (group D) day of VLC exposure, respectively. The exposure of VLC was done in labial aspect of cervical anterior teeth of mandible. The distance of exposure was as thick as 2 layers of celluloid strip and the histological specimens were stained by Hematoxylin Eosin. Each specimen was measured for its gingival epithelial thickness by using a micrometer and the number of neutrophil and macrophage were counted. The data of gingival epithelial thickness from 4 groups were analyzed by Kruskal Wallis. The number of neutrophil and macrophage were analyzed by u sing one way ANOVA. The results of this study showed that there were significant differences among groups on the thickness of gingival epithelial, the number of neutrophil and macrophage in the gingival connective tissue of Sprague dawley rats. The result of this study indicated that VLC exposure might decrease the thickness of gingival epithelial but increase the number of neutrophil and macrophage of gingival connective tissue of Sprague dawley rats.

Abstract

Carbonated hydroxyapatite is frequently used as bone graft material in dentistry. It is highly biocompatible, has osteoconductive properties, and functions as a drug delivery system. Propolis is a natural product from bees that has antibacterial and anti-inflammatory effects and is capable of accelerating wound healing. Incorporating propolis into carbonated hydroxyapatite was expected to enhance the wound-healing process by stimulating fibroblast growth and regenerating alveolar bone in the treatment of periodontitis. The aim of this study was to evaluate the effect of carbonated hydroxyapatite with incorporated propolis on the viability of NIH 3T3 fibroblast cells. This study used three treatment groups [carbonated hydroxyapatite with various concentrations of incorporated propolis (5%, 7.5%, and 10%)] and one control group (carbonated hydroxyapatite with no propolis). An MTT assay was carried out to assess cell viability, and absorbance readings were performed by using an ELISA reader. The data were analyzed by using one-way ANOVA. The results showed significant differences between all groups, and carbonated hydroxyapatite with 10% incorporated propolis has the highest cell viability level of all groups, while the control group has the lowest cell viability. In conclusion, adding propolis to carbonated hydroxyapatite could increase the growth of NIH 3T3 fibroblast cells. Keywords: Carbonated hydroxyapatite, Propolis, NIH 3T3 fibroblast cells, MTT assay
