Hypocholesterolaemic and hypoglycaemic effect of banana blossom were studied in high-cholesterol fed rats. Experimental groups were fed for 4 weeks, with casein as the basal diet (CN), in comparison with two diets containing 0.5% cholesterol (CD) and 0.5% cholesterol + 21% banana blossom powder (CDB). Serum total cholesterol, non-HDL-cholesterol level, and serum glucose concentrations were lower in CDB fed group compared with CD fed group. Lower serum cholesterol and glucose level (P<0.05) in CDB fed group were followed by higher faecal weight, caecal weight, caecal Lactobacilli, and Bifidobacteria population in CDB fed group compared to CD diet fed group. Lower serum AST level in banana blossom fed rats showed the reduction in oxidative stress induced by high cholesterol diet. Based on these data, it could be speculated that banana blossom incorporated experimental diets may modulate the hypocholesterolaemic and hypoglycaemic responses in Wistar rats.

The stroke-prone spontaneously hypertensive rat (SHRSP) showed an exaggerated response to a high-fat, high-cholesterol (HFC) diet, and the resulting reactive hypercholesterolemia was suggested to exacerbate the atherogenic process in this rat. We thus performed a quantitative trait locus (QTL) analysis on the serum cholesterol level of SHRSP before and after the HFC diet, with the final goal being the identification of the genetic mechanisms of its reactive hypercholesterolemia. Three hundred fifty-eight F2 rats between SHRSP and Wistar-Kyoto rat were employed in the study. The serum cholesterol and apoprotein E were measured before and after 2 wk of feeding with the HFC diet. Multiple QTLs for the basal cholesterol level were identified on chromosomes 1 and 5, whereas those for the postdietary cholesterol level were on chromosomes 7, 15, and 16. The cholesterol QTLs before and after HFC diet did not overlap with one another, implying that the involved metabolic processes were considerably different between the two conditions. Supporting this, VLDL and LDL cholesterol were the major components of the postdietary serum cholesterol, whereas the basal cholesterol level consisted mainly of HDL cholesterol. A substantial difference of the QTLs between males and females was observed, especially after the HFC diet. The QTL on chromosome 15 had an inverse effect on the cholesterol level, suggesting that the congenic substitution of the SHRSP fragment with that of Wistar-Kyoto rats could induce a greater cholesterol level in SHRSP. This observation is significant in establishing a new model for atherosclerosis with hypertension in rats.

Abstract Lipid metabolism and inflammation contribute to CVD development. This study investigated whether the consumption of cranberries (CR; Vaccinium macrocarpon) can alter HDL metabolism and prevent inflammation in mice expressing human apo A-I transgene (hApoAITg), which have similar HDL profiles to those of humans. Male hApoAITg mice were fed a modified American Institute of Nutrition-93M high-fat/high-cholesterol diet (16 % fat, 0·25 % cholesterol, w/w; n 15) or the high-fat/high-cholesterol diet containing CR (5 % dried CR powder, w/w, n 16) for 8 weeks. There were no significant differences in body weight between the groups. Serum total cholesterol, non-HDL-cholesterol and TAG concentrations were significantly lower in the control than CR group with no significant differences in serum HDL-cholesterol and apoA-I. Mice fed CR showed significantly lower serum lecithin–cholesterol acyltransferase activity than the control. Liver weight and steatosis were not significantly different between the groups, but hepatic expression of genes involved in cholesterol metabolism was significantly lower in the CR group. In the epididymal white adipose tissue (eWAT), the CR group showed higher weights with decreased expression of genes for lipogenesis and fatty acid oxidation. The mRNA abundance of F4/80, a macrophage marker and the numbers of crown-like structures were less in the CR group. In the soleus muscle, the CR group also demonstrated higher expression of genes for fatty acid β-oxidation and mitochondrial biogenesis than those of the control. In conclusion, although CR consumption elicited minor effects on HDL metabolism, it prevented obesity-induced inflammation in eWAT with concomitant alterations in soleus muscle energy metabolism.

The present study was undertaken to examine the effect of vitamin B12 on serum cholesterol levels and development of aortic atherosclerosis in New Zealand White male rabbits fed a high cholesterol diet. Twenty rabbits were divided into 4 groups matched for their baseline serum cholesterol values. Groups 1 and 2 received a normal diet, whereas groups 3 and 4 had cholesterol mixed with their chow. After 5 weeks, the serum cholesterol of groups 3 and 4 increased by approximately 12 fold compared to groups 1 and 2. At that point, vitamin B12 was administered in the drinking water (1000 micrograms/l) to rabbits in groups 2 and 4. At week 8, the Vitamin B12 dose was increased to 2400 micrograms/l for group 4. At 12 weeks into the study, rabbits in group 4 (high cholesterol diet plus vitamin B12) had a serum cholesterol level of 919 +/- 270 mg/dl while those of group 3 (high cholesterol diet) had a serum cholesterol level of 1417 +/- 250 mg/dl. At the end of the study, rabbit aortas were excised, fixed, and stained with fat-red-B, a dye for lipid. Comparison of the aortas of rabbits that received the lipid rich diet revealed that animals given additional vitamin B12 had significantly decreased surface area of fat deposition. These data suggest the potential role for vitamin B12 as a safe and inexpensive pharmacological intervention for the modification of the progression of human atherosclerosis.

Priskila M, Ariningrum D, Suparyanti ES. 2008. Effect of garlic (Allium sativum Linn.) extract on reduction of total cholesterol and HDL cholesterol ratio in hypercholesterolemic rats (Rattus norvegicus). Biofarmasi 6: 45-51. Garlic has been widely recognized as herbal medicine for prevention and treatment of cardiovascular disease, atherosclerosis, and hyperlipidemia. The main bioactive compound, allicin, can influence cholesterol metabolism, reduce total cholesterol and increase HDL cholesterol. The purpose of this research was to find out the effect of garlic extract on the reduction of total cholesterol and HDL cholesterol ratio in hypercholesterolemic rats. This research was an experimental research with pre and post-test control group design. The research used male Wistar rats (Rattus norvegicus) with ±3 mounts old and ±200 grams of body weight. The rats were divided into two groups, group I and II; each group consisted of 15 rats. Before the treatment, all rats were induced by a high-cholesterol diet for two weeks, to get a hypercholesterolemic condition. Group I, as a control group, were induced by a high-cholesterol diet, while group II, treatment group, were also induced by a high-cholesterol diet orally by 0.432 grams garlic extract /200 grams body weight/day. The treatment occurred for 25 days. The data were taken before the treatment and after the last treatment, by taking the blood from orbital sine of rats which been fasted for 12 hours, and the level of serum cholesterol total and the level of serum HDL cholesterol were checked from both groups, then the results were analyzed with t-test. Based on the results, it could be concluded that the oral induction of 0.432 grams garlic extract /200 grams body weight/day for 25 days on rats, could not reduce total cholesterol, therefore the serum total cholesterol and HDL cholesterol ratio was not significant (p>0.05). Meanwhile, the decrease of total cholesterol in treatment group and the decrease of HDL cholesterol in both groups were significant (p<0.05).

High Cholesterol

Seaweed has potential nutrient content such as carotenoids, vitamins, fatty acids, carbohydrates, minerals, and other essential substances. Carotenoids have important biological functions as an antioxidant, and immunostimulatory which can prevent the disease, anti-inflammatory, anti-stress, anti-aging, and protect the skin from the harmful effects of ultraviolet radiation. Seaweed generally consumed as a vegetable by people in Bali, known as the local name Bulung Boni (Caulerpa spp.) and Bulung Sangu (Gracilaria spp.).. So far there has been no report or results of research on the effects of extract ethanol of Bulung Boni (Caulerpa sp.) and Bulung Sangu (Gracilaria sp.) as an antioxidant that can prevent lipid peroxidation which can be seen in decreased level of MDA in liver tissue or blood plasma. Therefore it is necessary to determine of plasmaMDA level of Wistar rat after fed high cholesterol diet treated with extract ethanol of Caulerpa sp. and Gracillaria sp. This experimental study used completely randomized design. Research using total of 24 Wistar rats divided into six sample groups of equal size, all fed with a diet high in cholesterol especially in negative control. The study consisted of negative control group (standard diet), positive control group (high cholesterol diet), high-cholesterol diet with Caulerpa sp. extract dose of 20 mg and 60 mg/100 g, high cholesterol diet with Gracilaria sp. extract dose of 20 mg and 60 mg/100 g body weight rat per day.The study resulted that rats fed high cholesterol diet with treated extract ethanol Caulerpa sp. and Gracilaria sp. with a dose of 20 mg and 60 mg per 100 g body weight rat / day had plasma MDA level significantly lower (p <0.05) compared with rats fed high cholesterol diet without treated with extract of Caulerpa sp. and Gracilaria sp.

The effects of fermented skim milk versus unfermented skim milk of camel on the levels of cholesterol in blood were investigated in rats. Levels of serum cholesterol and LDL-C/ HDL-C ratio were decreased significantly in Wistar rats that fed with a cholesterol-enriched diet and administered fermented skim camel milk compared with rats administered unfermented milk (P˂0.05). Furthermore, histopathological evaluation showed that liver tissue degeneration, apoptosis/necrosis, inflammation, and fatty changes (steatosis and fibrosis) decreased significantly at (P˂0.05) in the rats that fed with fermented skim camel milk compared to the rats which fed unfermented skim camel milk. Based on these results it can suggest that fermented skim camel milk might reduce the risk of hypercholesterolemia development in rats. The hypocholesterolemic and hepatoprotective effects of fermented skim camel milk were evident.
