Nerve Cell Death

BACKGROUND: Consumption of foods and drinks high in energy, fat, and/or sugar beyond the recommended quantities can cause obesity, which triggers the incidence of brain nerve cell death related to oxidative stress, high levels of tumor necrosis factor (TNF)-α and triglycerides, and low high-density lipoprotein (HDL) levels. Progressive nerve cell death causes decreasing cognitive performance. This study aims to prove that an American Institute of Nutrition committee in 1993 (AIN-93M) diet modified with high-fat-high-fructose (HFHF) can decrease the number of hippocampal neurons. A decrease in the number of hippocampal neurons indicates progressive nerve cell death.METHODS: An experimental study using a post-test control group design was carried out using male Sprague Dawley rats. Samples were selected using simple random sampling to divide them into two groups, Group I was AIN-93M-modified HFHF diet (n=14) and Group II was AIN-93M standard (n=16). The number of visible neurons was measured in the hippocampus area of Sprague Dawley rats’ brains, stained with haemotoxylin and eosin (H&E) and scanned under 400x magnification. Neurons were counted in 10 visual fields using the "Cell_Count" application.RESULTS: The data were analysed by Pearson’s correlation test using SPSS. The results show that rats in Group I had a greater weight gain and fewer neurons than those in the Group II (p=0.023, r=-0.413).CONCLUSION: The consumption of foods high in fat and fructose can cause an increase in nerve cell death, as shown by the decrease in the number of hippocampal neurons.KEYWORDS: brain nerve cells, high fat, high fructose, increased body weight

Introduction: Xiang Sha Yang Wei Wan (XSYWW) is a Chinese traditional medicine that is used for gastrointestinal disorders, specifically gastric ulcer in many countries of South-East Asia. The aim of the study was to evaluate the potential effects of XSYWW on ethanol-induced gastric ulcer in rats by means of histological Study. On a similar basis of treatment, ranitidine, a conventional medication was used as gold standard. Methods: Fifty five male Sprague-Dawley rats (250-300 gm) were divided into four groups. Group I (ethanol treated group) was the control group and gastric ulcers were induced by administering 100% ethanol (1 ml/200 g). Group II (Pre-treatment group) was divided into two subgroups; they were orally fed with 1.0 gm/kg and 2.0 gm/kg respectively of XSYWW solution. Thirty minutes later they were administered with absolute ethanol as in group I. Group III, was given an oral dose of 2gm/kg of XSYWW solution after one hour of ethanol administration. Group IV was given an oral dose of 200mg/kg ranitidine solution after one hour of ethanol administration. Five rats from groups I, III and IV were sacrificed on day 1, 2 and 3 while the animals of group II were sacrificed one hour after ethanol administration. Results: Histological study of the stomachs from ethanol treated rats showed multiple ulcers of various depths that reached the muscularis and the serosa. Conclusion: Pre or post-treated rats with XSYWW showed that XSYWW has protective effect against ethanol-induced gastric mucosal lesion. However, there was a faster and more complete healing process in the ranitidine treated group when compared to the XSYWW treated subjects.

Abstract The fish paste product, fish balls ‘tsumire’, is a traditional type of Japanese food made from minced fish as well as imitation crab, kamaboko and hanpen. Although tsumire is known as a high-protein and low-fat food, there is a lack of scientific evidence on its health benefits. Hence, we aimed to investigate the effects of tsumire intake on organ weight and biomarker levels in Sprague–Dawley rats for 84 d as a preliminary study. Six-week-old male Sprague–Dawley rats were divided into two groups: group I, fed normal diets, and group II, fed normal diets with 5 % dried tsumire. Throughout the administration period, we monitored their body weight and food intake; at the end of this period, we measured their organ weight and analysed their blood biochemistry. No significant differences were observed with respect to body weight, food intake, organ weight and many biochemical parameters between the two groups. It was found that inorganic phosphorus and glucose levels were higher in group II rats than in group I rats. On the other hand, sodium, calcium, amylase and cholinesterase levels were significantly lower in group II than in group I. Interestingly, we found that the levels of aspartate aminotransferase, alanine transaminase, lactate dehydrogenase and leucine aminopeptidase in group II were significantly lower than in group I, and that other liver function parameters of group II tended to be lower than in group I. In conclusion, we consider that the Japanese traditional food, ‘tsumire,’ may be effective as a functional food for human health management worldwide.

ABSTRACTObjectives: The aim of this study was to investigate the effects of low levels of zinc intake on the rat mandible and maxilla during growth and to compare these results with those of zinc-containing rats.Methods: The study was carried out on 14 Sprague-Dawley rats. The rats were randomly divided into two groups. Group I rats were fed with a Zn-deficient diet, and Group II rats with a Zn-containing diet. At the end of the fourth week on the experimental diet, all the rats were killed and blood samples were taken. Serum Zn levels were measured by atomic absorption spectrophotometry. Then, the s ulls and mandibles were freed from soft tissues and measurements were made on the dry skulls, the mandibles, and teeth in both of the two groups.Results: The zinc-deficient group showed a significantly lower value in dry skull, mandible, and teeth measurements when compared with those of the Group II.Conclusions: Changes in zinc intake might exert an effect on the growth of craniofacial structures. A low-zinc diet during adolescence might slow bone and teeth growth and enhance the risk of oral, periodontal, and orthodontic problems in later years. (Eur J Dent 2009;3:10-15)

Ethane in alveolar expirate may have its source in organs other than the lung and be transported to the lung for elimination. We determined ethane production rates in rats (group I) ventilated with hydrocarbon-free air (HFA) before and after exsanguination. To determine whether the lung is the source of increased ethane production during exposure to 100% O2, we measured ethane in the expirate of nine exsanguinated, Sprague-Dawley rats (group II) mechanically ventilated with HFA and then with 100% O2. In all nine animals, ethane elimination rates on 100% O2 increased compared with HFA values. In five of the nine rats, HFA ventilation was reinstated after O2 (group III). In all five, ethane elimination fell with HFA ventilation compared with the value on 100%. Six rats with circulation intact were ventilated with HFA and then 100% O2 (group IV). Ethane production rate for group IV animals breathing HFA was not significantly different from the exsanguinated animals in group II while ventilated with HFA. The mean increase in ethane production for the group II animals was not significantly different from the group IV animals. Lung slices from four other rats (group V) were incubated in saline at 37 degrees C with FeCl2 (10 mg) added to enhance free radical formation. Paired lung samples from the same rat were incubated with either HFA or 100% O2. Headspace gas was analyzed chromatographically for ethane at 120 min. Mean ethane in the O2 samples was higher than for HFA. Rat lung tissue is the main source of increased ethane production during 100% O2 exposure.

Subsequent Exposure

It has been suggested that increased fructose intake is associated with obesity. We hypothesized that chronic fructose consumption causes leptin resistance, which subsequently may promote the development of obesity in response to a high-fat diet. Sprague-Dawley rats were fed a fructose-free control or 60% fructose diet for 6 mo and then tested for leptin resistance. Half of the rats in each group were then switched to high-fat diet for 2 wk, while the other half continued on their respective diets. Chronic fructose consumption caused leptin resistance, while serum leptin levels, weight, and adiposity were the same as in control rats that were leptin responsive. Intraperitoneal leptin injections reduced 24-h food intake in the fructose-free group (73.7 ± 6.3 vs. 58.1 ± 8 kcal, P = 0.02) but had no effect in fructose-fed rats (71.2 ± 6.6 vs. 72.4 ± 6.4 kcal, P = 0.9). Absence of anorexic response to intraperitoneal leptin injection was associated with 25.7% decrease in hypothalamic signal transducer and activator of transcription 3 phosphorylation in the high-fructose-fed rats compared with controls ( P = 0.015). Subsequent exposure of the fructose-mediated, leptin-resistant rats to a high-fat diet led to exacerbated weight gain (50.2 ± 2 g) compared with correspondingly fed leptin-responsive animals that were pretreated with the fructose-free diet (30.4 ± 5.8 g, P = 0.012). Our data indicate that chronic fructose consumption induces leptin resistance prior to body weight, adiposity, serum leptin, insulin, or glucose increases, and this fructose-induced leptin resistance accelerates high-fat induced obesity.
