Abstract: Canola oil is a source of vegetable oils which contains high unsaturated fats that can reduce the risk of coronary heart disease, especially atherosclerosis. One of the trigger factors of atherosclerosis is hypercholesterolemia. This study aimed to evaluate the histopathological features of aorta and the levels of LDL and HDL cholesterols in Wistar rats fed with high fat diet and canola oil. There were 20 Wistar rats in this study, divided into four groups: group A, the negative control; group B with high-fat diet (1 ml lard and 1 ml yolk daily); group C with high-fat diet and 0.1 ml of canola oil daily; and group D with high-fat diet and simvastatin 0.2 mg daily. The results showed elevated levels of LDL and HDL cholesterols in the treated groups compared to the control group. The histopathological features revealed many foam cells in the aorta wall (intima and media layers) of group B, whereas group C had fewer foam cells. No foam cells were found in group D. Conclusion: Although the mean LDL and HDL cholesterol levels of all treated groups were higher than of the control group, canola oil could reduce foam cell formation.Keywords: canola oil, foam cell, LDL and HDL cholesterols Abstrak: Minyak kanola merupakan salah satu sumber minyak nabati yang tinggi lemak tak jenuh yang dapat mengurangi risiko penyakit jantung koroner terutama aterosklerosis. Salah satu faktor pencetus aterosklerosis ialah hiperkolesterolemia. Penelitian ini bertujuan untuk mengevaluasi gambaran histopatologik aorta serta kadar kolesterol LDL dan HDL tikus wistar yang diberi diet tinggi lemak dan minyak kanola. Penelitian ini menggunakan 20 ekor tikus Wistar, yang dibagi dalam 4 kelompok, yaitu: kelompok A sebagai kontrol negatif; kelompok B dengan diet tinggi lemak yaitu lemak babi sebanyak 1 ml dan kuning telur sebanyak 1 ml per hari; kelompok C dengan diet tinggi lemak dan minyak kanola sebanyak 0,1 ml per hari; dan kelompok D dengan diet tinggi lemak dan simvastatin sebanyak 0,2 mg per hari. Hasil penelitian menunjukkan terdapat peningkatan rerata kadar kolesterol LDL dan HDL tikus wistar yang diberi perlakuan dibandingkan tikus kontrol yang hanya diberi pakan dan air. Pada gambaran histopatologik kelompok B terlihat adanya sel-sel busa pada dinding aorta (tunika intima dan media), sedangkan pada kelompok C sel-sel busa terlihat berkurang. Tidak terlihat sel busa pada kelompok D. Simpulan: Walaupun rerata kadar kolseterol LDL dan HDL meningkat pada kelompok perlakuan, minyak kanola dapat menurunkan pembentukan sel busa.Kata kunci: minyak kanola, sel busa, kolesterol LDL dan HDL

Cardiovascular disease causes the highest mortality rate in the world. Atherosclerotic plaque is the most common etiology of cardiovascular disease. High levels of cholesterol in circulation is the pathophysiology of atherosclerosis formation. Atherosclerosis risk can be lowered to 20-40% with statins. Statins are effective in lowering total and LDL cholesterol, but these drugs have been reported to cause side effects. Therefore, it needed an alternative medicine to prevent the process of atherosclerosis using kepuh leaves (Sterculia foetida). Flavonoids contained in Kepuh leaves improve lipid profiles. The aims of this study is to prove the effectiveness of Sterculia foetida in lowering cholesterol, triglyceride and reduce the amount of foam cells on high-fat-diet induced rats. The research design is quasi-experimental with post test only design. Animals are grouped into normal group, negative control group and three treatment groups that were given kepuh leaves extract at the dose of 200 mg/kgBB, 400 mg/kgBB, and 800 mg/ kgBB. Rats were given high-fat diet of initial intravenous adrenaline injection 0.006 mg/200 gBB and duck egg yolks 5 g/kgBB for 21 days. Cholesterol and triglycerides were measured by enzymatic methods and aortic tissue stained with HE. ESf reduce cholesterol significantly and reduce the amount of foam cells on aorta.Keywords: cholesterol, triglyceride, kepuh leaves, foam cell, high-fat-diet

Background: The extract of Corchorus olitorius has a reasonable content of vitamins A and C, calcium, iron and fibre, and therefore enjoys a universal application in the treatment of some disease conditions, even as the whole leaf is a very important component of food in so many cultures. Purpose: The study was designed to investigate the effect of Corchorus olitorius extracts on the testis of adult Wistar rats. Method: A total number of thirty two adult Wistar rats weighing between 180 and 200 grammes separated into four groups labeled A,B,C and D respectively were used for the study. Animals in group A which served as the control group were fed with the normal rat chow and water only. The group B rats were administered 100mg/kg body weight of aqueous extract of Corchorus olitorus; while those in group C were administered 500mg/kg body weight of the extract. The group D rats received 1000mg/kg body weight of the extract. For a period of four weeks, the different experimental animal groups received the respective aforementioned treatments once daily, around nine- o’clock in the morning through oral intubation. At the end of the 28 day treatment, the animals were sacrificed and the testes harvested for histological, investigation, and through cardiac puncture, blood samples for some hormonal studies was also collected and investigated using standard laboratory standards. Results: Observations made showed that the extract produced no histological distortions, degenerative or defective effects on the testicular tissues. The testosterone levels of group B, C, and D rats were observed to be significantly higher (P<0.005) than that of the group A (control group).ound: The extract of Corchorus olitorius has a reasonable content of vitamins A and C, calcium, iron and fibre, and therefore enjoys a universal application in the treatment of some disease conditions, even as the whole leaf is a very important component of food in so many cultures.

This study aims to look at the histopathological picture of the dorsal arteries of the penis of the hiperlipidemic wistar rats (Rattus novergicus) induction by high-fat diet that seen in terms of lumen diameter and thickness of the arterial endotelium wall. Hyperlipidemia is a risk factor for ateriosclerosis in the penile arteries causing erectile dysfunction in men. This study is an experimental study with a randomized posttest only control goup design. The sample are  10 individuals adult male wistar rats aged 3-4 months with a range of body weight 150-200 grams. Before treatment, adaptation was carried out for 7 days. After that the sample rats in the treatment group were made hyperlidemic by feeding lard for 50 days. Then surgery is performed for histopathological preparations at the posttest. To determine the differences in endotelium thickness and arterial lumen diameter in the two groups, an independent t-test was used. Thick diameter data of the endotelium and dorsal arteries of the penis of the wistar rat between the lower treatment group and the control group. The difference that occurred was statistically significant (p <0.05). So it can be concluded that the provision of high-fat diet (hyperlipidemia) decreases the lumen diameter and endotelium thickness of dorsal arteries penis.

Hyperlipidemia due to a high-fat diet (HFD) is a risk factor for inducing insulin resistance (IR) and adverse effects onpancreatic β-cells in obesity and type 2 diabetes mellitus. This relationship may be due to activation of the hexosaminebiosynthesis pathway. Administration of exogenous glucosamine (GlcN) can increase the end product of this pathway(uridine-5′-diphosphate-N-acetyl-glucosamine), which can mediate IR and protein glycosylation. The objective of this study was to evaluate the effects of oral GlcN and HFD on IR and pancreatic histologic damage in a 22 wk study of 4 groups of male Wistar rats: control group with normal chow diet, HFD group (24%. g/g lard), GlcN group (500 mg/kg−1 per day of glucosamine hydrochloride in drinking water) and HFD plus oral GlcN. Metabolic variables related to IR that were measured included triglycerides (TG), free fatty acids (FFAs) and malondialdehyde (MDA). Histopathologic evaluation of the pancreas was also performed. The results showed IR in the HFD group, which had increased pancreatic nuclear pyknosis and vacuolization, with fatty infiltration and structural alteration of the islets of Langerhans. TG, FFAs and MDA were higher in serum and pancreatic tissue as compared with the control group. The GlcN group did not develop IR and had only mild nuclear pyknosis with no significant change in the pancreatic content of TG, FFAs and MDA. However, the combined administration of GlcN and HFD attenuated IR and improved TG, FFAs and MDA levels in serum and pancreatic tissue and the pancreatic histopathologic changes, with no significant differences as compared with the control group. These findings suggest that the oral GlcN at a dose of 500 mg/kg−1 is protective against IR and the pancreatic histologic damage caused by HFD.

Background Adipose and hepatic metabolic dysfunctions are critical comorbidities that also aggravate insulin resistance in obese individuals. Melatonin is a low-cost agent and previous studies suggest that its use may promote metabolic health. However, its effects on some comorbidities associated with obesity are unknown. Herein, we investigated the hypothesis that melatonin supplementation would attenuate adipose-hepatic metabolic dysfunction in high fat diet (HFD)-induced obesity in male Wistar rats. Materials and methods Twenty-four adult male Wistar rats (n = 6/group) were used: Control group received vehicle (normal saline), obese group received 40% high fat diet, melatonin-treated group received 4 mg/kg of melatonin, and obese plus melatonin group received 40% HFD and melatonin. The treatment lasted for 12 weeks. Results HFD caused increased food intake, body weight, insulin level, insulin resistance and plasma and liver lipid but decreased adipose lipid. In addition, HFD also increased plasma, adipose and liver malondialdehyde, IL-6, uric acid and decreased Glucose-6-phosphate dehydrogenase, glutathione, nitric oxide and circulating obestatin concentration. However, these deleterious effects except food intake were attenuated when supplemented with melatonin. Conclusion Taken together, the present results indicate that HFD exposure causes adipose-hepatic metabolic disturbance in obese animals, which are accompanied by oxidative stress and inflammation. In addition, the present results suggest that melatonin supplementation attenuates adipose-hepatic metabolic dysfunction, accompanying obesity by suppression of oxidative stress/inflammation-dependent mechanism and increasing circulating obestatin.
