Abstract

ABSTRACT Excessive energi consumption of high-fat diet increase the body’s adipose tissue which also affect the increased secretion of leptin, this is because leptin secretion is proportional to the mass of adipose tissue. Leptin activates the lateral hypothalamus as the center of hunger and feeding activity. The aim of this study was to obtain the relationship between high trans fat feeding on male Wistar rats and feeding activity. This method uses male Wistar rats (Rattus norvegicus) as an animal model. Sixteen rats were grouped into 4 treatment groups. The first group was given additional feed 20% trans fat, the second group was given additional feed 40% trans fat, a third group was given additional feed 60% trans fat, and the last as a control group. This feed was given once a day for 70 days. Observation of activities perform using Opto-varimex® auto-track system ver. 4.31. The results showed an corellation between activity based doses of trans fat. Keywords: Opto-varimex®, Trans fat, Activity, Wistar rat.

Abstract

ABSTRACT Myoglobin is a hemoprotein that contributes to intracellular oxygen storage and facilitates diffusion oxygen into mitochondria. Myoglobin production will increase as low levels of environmental oxygen called hypoxia. When oxygen in tissue is low, the body will respond by forming myoglobin in some tissues, such as muscle tissue. The aims of this study was to detect DNA fragments of myoglobin along 114pb in muscle tissue of marine animals are capable to live in the oxygen minimum zone, such as the green turtle, mackerel tuna and hammerhead sharks. The oxygen minimum zone is zone of oceans which have low dissolved oxygen levels at > 1,4μLO2L-1, the oxygen levels can be categorized as hypoxic conditions. This study was conducted in the Biochemistry laboratory, State University of Jakarta. This study used descriptive method by PCR and electrophoresis. The results indicated that myoglobin found in muscles of marine animals were capable live in oxygen minimum zone such as the green turtle, mackerel tuna and hammerhead shark. This information can be used as the basic that the tissue able to make adaptation strategy towards low oxygen environmental levels by increasing formation of myoglobin in muscle tissue.
