Diabetes mellitus is now becoming a major health problem with an increasing
prevalence rate. The risk for diabetes mellitus results from lifestyle changes
which is related to diet and physical activities. Diabetic patients would have the
clinical characteristics of diabetes mellitus such as hyperglycaemia and lipid
abnormalities which significantly contribute to produce complications of
diabetes mellitus. Attention to diet and weight management, combine with
exercise may help to improve the glycaemic control and lipid profiles. A prompt
and adequate treatment to prevent or delay the complications of diabetes
mellitus by alleviating these deleterious characteristics of diabetes mellitus is
needed. Thus, the present study was undertaken to assess the potential of exercise and dietary polyunsaturated fatty acid (PUFA) intervention in
alleviating the detrimental effects of diabetes mellitus.
The efficacy of exercise and dietary PUFA intervention in streptozotocin (STZ)-
induced diabetes in rats was investigated on the basis of body weight, blood
glucose levels and blood lipid profiles. A total of 32 Sprague-Dawley male rats
weighing between 250-300 grams were divided equally into eight groups.
Diabetes mellitus was induced by giving a single intraperitoneal injection of
STZ at the dosage of 40 mg/kg.
Four groups were exercised daily by swimming for 8 weeks while the other four
groups were not subjected to any exercise. Menhaden oil, soybean oil and butter
were incorporated into the treatment diets for both exercise and non-exercise
groups. The treatment diets were defined as follows: rat chow diet only (Control
diet), rat chow added with 6.66% (w/w) menhaden oil and 3.34% (w/w) soybean
oil (Diet 1), rat chow added with 3.34% (w/w) menhaden oil and 6.66% (w/w)
soybean oil (Diet 2) and rat chow containing 10% (w/w) butter (Diet 3).
Experiment I was conducted to determine the body weight and blood glucose
levels of rats at week 0, 2, 4, 6 and 8. In Experiment II, blood was collected at the
end of 8 weeks for the determination of blood lipid profiles that encompassed:Triglycerides, Total cholesterol, High-density lipoprotein (HDL)-cholesterol and
Low-density lipoprotein (LDL)-cholesterol.
The results obtained from this study showed that exercise and dietary PUFA
intervention can be considered as the integral components of treatment and
prevention strategy in diabetes mellitus by improving the body weight control
and blood glucose levels. The exercise and dietary PUFA intervention groups
significantly reduced the body weight gain and showed the hypoglycaemic
effects over a period of eight weeks in STZ-induced diabetic rats when
compared to the non-exercise group and the normal control group, which is
non-diabetic rat. This study also has documented a significance of exercise and
dietary PUFA intervention to improve the lipid abnormalities by lowering the
triglycerides, total cholesterol and LDL-cholesterol levels.
The values indicated in the treatment and control diet are highly difference as
compared to the normal control, which are non-diabetic. Therefore, the impacts
of exercise and dietary PUFA intervention to improve body weight gain, blood
glucose levels, and blood lipid profiles could be used as an indicator in
assessing the health status of patient at high risk of diabetes mellitus or in the
diabetic patient itself.Thus, results obtained in the present study suggested that exercise and dietary
PUFA intervention may have an impact on alleviating the detrimental effects of
diabetes mellitus by regulating body weight changes, blood glucose levels, and
blood lipid profiles. Indeed, the supplementation of dietary PUFA, in
combination with exercise did have some effects in improving and delaying
those risk factors of complication in diabetes mellitus. |
