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.

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

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.

The present study was carried out to find out the gastroprotective effects of the leaves extracts of Dypsis lutescens (H.Wendl.)  and Caryota Urens (L.)   in aspirin-induced gastric ulcer in rats. The ethanolic and aqueous extracts were prepared from the leaves of Dypsis lutescens and Caryota Urens and were used for this study. All procured animals were divided into seven groups. Each group contain n = 6, all groups except the normal control treated with aspirin 150 mg/kg oral. Group, I served as the normal control group which received normal saline, group II served as negative control and group III as standard group receiving 20 mg/kg omeprazole and 4th to 7th groups treated with leaves extracts of Dypsis lutescens and Caryota urens respectively. Treatment was given to group II to group VII rats in every 24 h for seven days. After 24 h fasting, on the 8th-day stomach contents were aspirated under anaesthetic condition to check free and total acidity. Stomachs were opened in all sacrificed animals along the greater curvature to estimate ulcer index, percentage protection and histopathology studies. The results of the present study revealed that the severity of aspirin-induced ulceration was significantly (P < 0.05) decreased in Dypsis lutescens extracts treated groups in comparison with the control and Caryota urens treated groups.  It was observed that the free and total acidity significantly decreased in the aqueous extract of Dypsis lutescens treated group when compared with the negative control and Caryota urens treated groups.

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.

Background: Inflammation is a body response caused by injury and infection. Pulpitis is a pulp tissue inflammation which is the continuous process of pulp hyperemia by bacteria invasion. Myrmecodia pendans or Sarang semut is known to contain flavonoid compound which has the anti inflammation effect. The purpose of this study is to investigate the effect of Myrmecodia pendans ethanol extract on the healing process of pulp inflammation.Materials and Methods: This experimental study involved pre- and post-in vivo treatment of 27 Sprague Dawley rats in which the inducted pulpitis model was obtained by injecting 0.01 mL Porphyromonas gingivalis into the dental pulp for 48 hours. Subjects were divided randomly into Group I (negative control), Group II (pulpitis treated by Myrmecodia pendans extract ethanol as treatment group), and Group III (pulpitis treated by Ca(OH)2 as positive control group). Group II and III as pulpitis treatment groups were divided into subgroups based on the induction periods of 48 hours (2 days), 168 hours (7 days), and 366 hours (14 days). All specimens were processed into the slides and evaluated microscopically for the healing process.Results: The result of this study showed significant difference (p<0.05) among groups on day 2, 4 and 7. On day 4, the pulpitis treatment group of Myrmecodia pendans extract showed better healing process than Ca(OH)2. On day 7, the pulpitis treatment group of Ca(OH)2 showed better healing process than Myrmecodia pendans extract. On day 14, both of the pulpitis treatment groups showed normal pulp.Conclusion: Myrmecodia pendans ethanol extract is effective for the healing process of inflamed pulp.Keywords: inflamed pulp, Myrmecodia pendans, sarang semut, Ca(OH)2 , healing process

Abstract. Six Holstein bulls were housed in a climate-chamber under constant light regimen and after two weeks of preconditioning at 15°C, 60% relative humidity RH (day) and 12°C, 60% RH (night) were subjected to two weeks of heat exposure. This involved one week at 30°C and 60% RH (day) and 25°C and 60% RH (night) and a further week at 35°C, 60% RH (day) and 30°C, 60% RH (night). Three bulls were untreated (group I) and 3 bulls were treated (group II) just before and during heat exposure with a prolactin inhibitor to study the possible physiological role of prolactin on the regulation of water, potassium and sodium. Serum prolactin levels increased significantly (P < 0.01) in group I from the control value of 6 ng/ml to 33 and 44 ng/ml when the ambient temperature was increased (weeks 3 and 4) and then decreased to 21 and 12 ng/ml after reduction in temperature during weeks 5 and 6, respectively. For group II prolactin values decreased under the treatment with the prolactin inhibitor to 0.5 ng/ml and remained at this level throughout the experiment. GH levels were unaffected by heat treatment or by treatment with prolactin inhibitor. There were no differences between groups I and II in respiratory rate, pulse rate and rectal temperature. Water intake increased in both groups under heat exposure but decreased significantly afterwards only in group II. Differences in urinary excretion volume and blood serum osmolality were not significant. Urinary potassium and sodium excretion were unchanged in group II but increased with heat exposure in group I. During heat exposure 2 bulls of group II lost weight despite maintaining food intake.

The present study was conducted on 12 cow calves with infected wounds, irrespective of sex and breed, divided into two groups having 6 cow calves each. The animals of group I were treated with silver nano particle gel and the animals of group II were treated with povidone iodine dressing for 7 consecutive days. Histopathological changes were recorded at different time interval in both the groups. Studies revealed that there was marked re-epitheliazation and hyperplasia with considerable thickening of epidermis and large amount of collagen deposition in granulation tissue in group I as compared to group II. Histopatathological findings clearly suggest that the group treated with silver nano particle gel showed better and faster healing of wound as compared to povidone iodine treated group. Therefore clinical use of silver nano particle gel can be advocated for wound dressing in cow calves.

AbstractTo investigate the effect of simulated weightlessness on the pharmacokinetics of orally administered moxifloxacin and the antacid Maalox or the antidiarrheal Pepto-Bismol using a tail-suspended (TS) rat model of microgravity. Fasted control and TS, jugular-vein-cannulated, male Sprague-Dawley rats received either a single 5 mg/kg intravenous dose or a single 10 mg/kg oral dose of moxifloxacin alone or with a 0.625 mL/kg oral dose of Maalox or a 1.43 mL/kg oral dose of Pepto-Bismol. Plasma concentrations of moxifloxacin were measured by HPLC. Pharmacokinetic data were analyzed using WinNonlin. Simulated weightlessness had no effect on moxifloxacin disposition after intravenous administration but significantly decreased the extent of moxifloxacin oral absorption. The coadministration of moxifloxacin with Maalox to either control or TS rats caused significant reductions in the rate and extent of moxifloxacin absorption. In contrast, the coadministration of moxifloxacin with Pepto-Bismol to TS rats had no significant effect on either the rate or the extent of moxifloxacin absorption. These interactions showed dose staggering when oral administrations of Pepto-Bismol and moxifloxacin were separated by 60 min in control rats but not in TS rats. Dose staggering was more apparent after the coadministration of Maalox and moxifloxacin in TS rats.

Abstract Two-dimensional gel electrophoresis (2-DE) was used to detect fluoride-induced alterations in the proteome of the rat hippocampus. Male Sprague-Dawley rats (n=30) were subjected to treatments three weeks after weaning. Animals of the first group were injected intraperitoneally (i.p.) with aqueous NaF (20 mg/kg/body weight/day), the second group, injected with physiological saline, served as the control. After 30 days, the body weight of the fluoride-treated rats was lower than that of the control, and F– levels in serum were higher than in the control. The hippocampus was subjected to proteomic analysis, and the fluoride-treated group was found to contain 19 up-regulated and eight down-regulated proteins. The proteins, identified by mass-spectroscopic analysis of their fragments obtained after digestion, were found to be involved in amino acid biosynthesis, the insulin signaling pathway and various other crucial functions. Our results also provide useful information on the mechanism of the reduction of the learning ability and memory induced by F.
