Abstract

Hydrilla verticillata is an aquatic weed, can build symbiosis and also become a substrate of freshwater fungi. Some of freshwater fungi that live in association with H. verticillata are pathogenic fungi which were potentially used as controller for Fusarium oxysporum and Ganoderma boninense. The use of pathogenic fungi as a biocontrol is not consistent in the field. Therefore, this research aimed to find new fungus candidates that are stronger and more consistent in controlling pathogenic fungi. Freshwater fungi were isolated from H. verticillata. Identification was based on morphological characters. Molecular analysis was carried out for freshwater fungi which had the highest inhibition percentage to pathogenic fungi. The antagonism test was conducted by dual culture method. The mechanism of interaction of hyphae was observed under a microscope. Freshwater fungi was derived from H. verticillata stem are Aspergillus section flavi, Gliomastix sp., and Talaromyces sp. Antagonism test results showed that all fungi could inhibit the growth of pathogenic fungi. Based on molecular analysis used ITS region showed Talaromyces sp. could not identify to the level of species so that additional genes were required, namely beta-tubulin gene, in order to further identify Talaromyces sp.

Abstract

Coprophagous beetle has important role in decomposition of organic materials. This research aimed to study and analyze the diversity and abundance of coprophagous beetles in organic and non-organic farms. Coprophagous beetles were collected in organic farm of Bina Sarana Bakti and non-organic farm of Seruni in Cisarua, West Java. In each location, twenty dung traps were set up in corn plants, carrot plants, cabbage plants, and onion plants. Totally, 15 species (610 individuals) of coprophagous beetles belonging to two families i.e Scarabaeidae and Aphodiidae were collected. Coprophagous beetles in organic farms (389 individuals, 13 species) more divers than that in non-organic farms (221 individuals, 10 species). There was no dominant species in both of locations (C<0.5). The most dominant species in organic farm was Copris reflexus (49%) and in non-organic farm was Onthopagus pauper (52%). Beetles similarity in organic and non-organic farm was 67%.

Abstract

It is known that coffee has much phenolic components such as flavonoids and chlorogenic acids (CGAs) content for neutralizing oxidative stress. Gayo-arabica coffee is a typical arabica coffee which widely used by Gayo people in Aceh, Indonesia. The coffee plants also grow in Gayo. However, it has not clearly understood its effect for health. The study aimed is to analyze the Gayo-arabica coffee consumption on the levels of malondialdehyde (MDA) as an indicator of damage cells due to oxidative stress and superoxide dismutase (SOD) as a marker of antioxidant enzyme, after performing a single bout submaximal physical exercise. Male sedentary subjects (21-27 y.o), consisted of 36 men, divided into 3 groups: control (zero of coffee), Gayo1 (15 g coffee in 200 ml water), and Gayo2 (20 g coffee in 200 ml water). Coffee was given once, after rockport test as a single bout submaximal physical exercise. MDA serum and SOD serum were taken after 1 hour of coffee drinking. MDA serum decreased significantly in Gayo1 (8.01 uM) and Gayo2 (10.36 uM), compared to control (26.82 uM). SOD serum increased significantly in Gayo1 (114.81 ng/ ml) and Gayo2 (101.48 ng/ml), compared to control (24.024 ng/ml). Nevertheless, there was no significantly different between Gayo1 and Gayo2 on MDA and SOD serum (p≥0.05). We suggest that the Gayo-arabica coffee after single bout submaximal exercise can diminish stress oxidative in sedentary people.

Abstract

The Courgette or oyong (Luffa acutangula L. (Roxb)) is member of Cucurbitaceae mainly used as vegetable. Beside used as vegetables, courgette aslo used as keratolytic agent. This fact is supposed that this vegetables contain protease. This research is succeed to purified courgette’s protease by four step. That was precipitate by 70% ammonium sulphate saturation, purification using DEAE cellulose ion exchange chromatography and gel filtration chromatography using sephadex G-100 and G-75. Purified courgette’s protease had 81,922 U/mg for specific activity and 34 kDa molecular weight. This enzyme had the characteristic such as activated optimally at 37oC, pH 7 and 10 minute duration time. This enzyme activity can decrease by PMSF and H2O2, its remarkable that courgette protease is serine protease and had the thiol group in its structure. The ability to digest food proteins materials like boiled meat and boiled white egg by courgette protease proves that the courgette protease enzyme is could be used in enzyme replacement therapy in mild digestion problem.

Abstract

Allergy is a hypersensitive reaction in human due to human body produced IgE antibody more than regullary do as a response to the presence of allergens. Asthma and rhinitis are respiratory allergies, could be caused by genetics and environmental factors. The objectives of this study was to analyze the trigger factors of asthma and rhinitis patients at the Allergy-Immunology Polyclinic, Internal Medicine Department, Faculty of Medicine, University of Indonesia, Dr. Cipto Mangunkusumo National Center General Hospital, Jakarta. The skin test using grass mix pollen, cat, dog, cockroach, and dust mites allergens were done to 90 respiratory allergy patients. History of respiratory allergy from their parents, and environmental factors such as pets, cigarette smoke, and emotional state were asked and recorded. The patients mostly women, and most respiratory allergy patients could be detected by skin test using dust mites allergens, however, their reaction did not the same for other allergens. More than 50% patients of respiratory allergy have atopy from their parents, for most of patients, their emotional state and cigarette smoke in house could trigger the symptom of respiratory allergy.
