Abstract

ABSTRACT Gallstones are crystalline rock pile contained in the gall bladder. Actually, not only in the gallbladder, but also found in the bile ducts and can also be found in the liver. Stone found in the gallbladder is called cholelithiasis, while stones in the bile ducts called koledokolitiasis. Gallstone formation last long, 10-15 years. Gallstones are mute or silent stone, often without any complaints and symptoms manifest. Depending upon the size and number of gallstones are formed as well as the location, severity of symptoms can vary. Elements forming gallstones are cholesterol and calcium. More than 90% of gallstones are cholesterol stones (cholesterol composition > 50%) or mixed form (20-50% cholesterol element) and the remaining 10% is pigment stones (calcium dominant element and cholesterol <20%). Gallstone risk factors known by the acronym 4F, the Forty, Female, Fat, Family. That is, gallstones are more common in those aged over 40 years old, female, overweight and have a family history of gallstones. Medications can be used to break up gallstones. Treatment requires at least 6 to 12 months and managed to dissolve stones in 40-80% of cases. The use of drugs is recommended when mild symptoms and small stones or surgery is considered too risky. The risk of gallstone formation can be reduced by living a healthy lifestyle, especially to keep the weight off. Applying a diet that does not contain a lot of saturated fat helps reduce the risk of gallstones. Kata Kunci : Batu empedu, kolesterol, pigmen, gaya hidup sehat

Abstract

ABSTRACT This study aims to determine the types and characteristics of lactic acid bacteria contained in the Peda Mackerel. The research was conducted in April to June 2013 in the Microbiology Laboratory Biology Department, FMIPA UNIMED. This study used descriptive design using aseptic sampling techniques. Materials used are lactic acid bacteria taken from the Peda Mackerel and grown on MRS medium (de Man Rogosa Sharpe). Based on the research results of the identification and characterization of lactic acid bacteria in Peda Mackerel using Test morphology, Gram staining and Biochemical tests of the obtained 4 types of lactic acid bacteria on the Peda Mackerel. The genus of lactic acid bacteria found include Eubacterium, Lactobacillus, Leuconostoc and Staphylococcus.  Characteristics in general is a form of cocci and bacilli, Gram positive, catalase negative, non motile, the optimum temperature of 200C-400C and have type homofermentatif and heterofermentatif fermentation.

Abstract

ABSTRACT The purpose of this study is to determine the relationship of nutritional iron deficiency anemia as measured by haemoglobin (Hb) blood students with biochemistry learning outcomes of students majoring in biology FMIPA Unimed 2014. Data was collected through direct observation of the examination of blood haemoglobin levels and the value of the course biochemistry students obtained through formative tests conducted during the lecture Biochemistry. The population of the study was all students majoring in Biology Force 2013 that took a course of Biochemistry. Sampling was done by purposive sampling 2013 Extension class which followed the course of biochemistry with researchers as lecturers. Hemoglobin Blood level distinguished female and male students with criteria for no anemia, mild anemia, moderate anemia and severe anemia. The value of Biochemistry learning outcomes categorized as very competent (value A), competent (value B), quite competent (value C) and incompetent (the value of E). Relationship anemia iron deficiency nutritional students value of biochemistry learning outcomes expressed using the cross table. The results shows that students who are not anemia both women and men to obtain the value of learning outcomes studied biochemistry with very competent and competent category (grades A and B). Students who experience anemia only obtain the value of the study of biochemistry with quite competent category. Students who experience moderate anemia obtain the value of incompetent learning outcomes on biochemistry incompetent category (grades E or otherwise does not pass).
