Drug Seeking Behavior of Amphetamine Addicted Sprague-Dawley Rats Is Eliminated after Nutritional Supplementation

Aim: The effectiveness of nutritional supplementation on drug-seeking behavior of amphetamine-addicted rats during withdrawal was investigated using a biased conditioned place preference (CPP) paradigm. Method: Twenty-four male Sprague-Dawley rats exhibiting baseline preference for the black chamber during a 20-minute pre-conditioning exploration of the CPP box completed the study. On alternate days of an 8-day schedule, twelve rats (Group AMP) were randomly selected, given either amphetamine sulfate (5 mg/ml, i.p.) and confined to the white chamber;or vehicle (1 ml saline, i.p.) and confined to the black chamber. A significant increased percentage time spent and number of entries made by Group AMP to the drug-paired, white chamber on the test day confirmed amphetamine addiction. Group AMP subsequently received increasing doses of amphetamine over 6 days. Following acute drug withdrawal, their CPP performance was compared with that of vehicle treated rats (Group SAL). Groups AMP and SAL were equally divided and randomly assigned to animals fed chow reconstituted with the nutritional supplement (AMP-S and SAL-S) over 8 weeks or standard rat chow (AMP-N and SAL-N). CPP performances for all rats were determined blindly from video recordings following this period. Results: Nutritionally supplemented, amphetamine withdrawn rats (AMP-S) exhibited significantly decreased percentage entries and time spent in the white chamber (p ?ve, control animals. Conclusion: Drug-seeking behavior by amphetamine-addicted animals was eliminated after treatment with a nutritionally supplemented diet.

Rice Germination and Its Impact on Technological and Nutritional Properties:A Review

Grain germination is a process involving numerous factors that influence the biochemical processes inside the plant cells.This review covered the abiotic factors that lead to the germination and significantly impact the nutritional properties and digestion behavior of rice grains.The macro-and micro-nutrients can be changed depending on the intensity of the applied variables during germination.For instance,germination time can increase the protein content in the grain and concurrently reduce its protein digestibility.In most cases,the number of bioactive compounds present in rice grains are increased regardless of germination conditions.Germination can promote the complexation of nutrients and thus negatively interfere with the digestibility of macronutrients.This review highlighted the influence of the germination process on the nutritional quality of rice grains,providing information about the germination conditions and their impacts on the anabolic and catabolic reactions of the grain,emphasizing the health benefits.

Drug-Seeking Behavior Is Significantly Attenuated in Nutritionally Supplemented Cocaine Withdrawn Sprague-Dawley Rats

Aim: The effect of patented nutritional supplementation on drug-seeking behavior in cocaine addicted rats during acute drug withdrawal was investigated using a biased Conditioned Place Preference (CPP) paradigm. Method: Twenty-four (24) male Sprague-Dawley rats with pre-conditioned preference for the black chamber of the CPP box were randomly divided into Cocaine (COC) or Saline (SAL) treated groups. Rats (n = 12) treated with cocaine hydrochloride 20 mg/kg/ml, i.p. (COC group) were confined individually to the white chamber on days 1, 3, 5 and 7. On alternate days, they were given 1 ml saline vehicle, i.p. and confined to the black chamber. Control rats (SAL group, n = 12) received only vehicle on all 8 days and were confined on alternate days to the white or black chamber. Positive place preference was confirmed for COC rats, which subsequently received 6 increasing daily doses of cocaine. CPP performances of both COC and SAL rats were recorded following an acute 3-day withdrawal period. All animals were then randomly assigned to rats fed either chow reconstituted with the nutritional supplement (COC-S and SAL-S) or standard rat chow (COC-N and SAL-N) for 8 weeks, followed by final CPP performances. Results: Following supplementation, COC-S rats made significantly less entries and time spent in the white chamber (p < 0.05) compared with COC-N rats. COC-S rats exhibited significant place aversion to the white chamber similar to drug-naive animals;whereas COC-N continued to show positive place preference. Conclusion: Drug-seeking behavior that persisted during cocaine withdrawal was significantly diminished in the nutritionally supplemented.

A comparison of several indices for assessing body condition of Mongolian gazelle

Riney kidney fat index (RKFI), whole kidney fat index (WKFI), femur marrow fat index (FMFI), and tibia marrow fat index (TMFI) of 51 Mongolian gazelles (Procapra gutturosa), collected in Hulunbeier grassland, Inner Mongolian, China, were measured during spring, autumn and winter in 1997-98. These different indexes were compared for using them in assessing the body condition. There was a linear relationship (y=0.9444x-20.139; r=0.9454; p<0.01) between RKFI and KMFI. A linear relationship (y=0.9348x+1.1843; r=0.9875; P<0.01) between TMFI and FMFI also occurred for gazelles. There was a curvilinear relationship (y=31.44Ln(x) -44.403; r=0.8643; P<0.01) between FMFI and RKFI. FMFI remained high, while RKFI decreased to a certain extent. After most of the kidney fat was used, the femur marrow fat abruptly decreased. The results showed that the kidney fat index is more adequate for evaluating the population nutrition in good condition, but marrow fat index was more useful for assessing in poorer nutritional condition.

Dietary fat intake of Japanese male children and its associated factors: Results of the 1995 National Nutrition Survey in Japan

Aim: To clarify the factors associated with reported dietary fat intake by Japanese male children. Methods: This study is based on the data of a nationally representative cross-sectional study in Japan. Three hundred and seventy-seven male children (age, 6 - 11 years) whose households were sampled in the 1995 Comprehensive Survey of Living Conditions of the People on Health and Welfare, and the 1995 National Nutrition Survey and whose parents were identified through record linkage between the 2 survey data sets were enrolled. Results: The final dataset in this study consisted of 377 boys with 329 of their parents. Fifty-two boys were found to be overweight (13.8%). The reported dietary fat intake was higher among the overweight boys than among the non-overweight boys. Maternal obesity was significantly associated with obesity in male children. Boys who frequently consumed foods from the “fats and lipids” group and the “meat” groups, and children from nuclear families rather than 3- generation families reported high dietary fat intake. In addition, parental fat intake was also significantly associated with fat intake of male children. Conclusions: Child and parental dietary habits along with the household status should be considered when implementing nutritional education programmes to control dietary fat intake and reduce the obesity risks of male children.

Effects of grazing intensity to water source on grassland condition, yield and nutritional content of selected grass species in Northwest Ethiopia

Background:Savanna grasslands are globally important ecosystems consisting of one of the most extensive grazing lands with unique biodiversity.The objectives of the study were to assess the effect of grazing intensity on grassland ecosystem condition,herbaceous plant biomass production,and nutritional content of selected grass species.Methods:The study was conducted at Chagni Ranch,Northwest Ethiopia.Four transects to water source point at regular intervals of 20m between sampling plots along transects were used for data collection.The distance between the four transects was 200m in radius.Data were collected on grass composition,basal cover,litter cover,number of seedlings,and age distribution of dominant grasses(i.e.,young,medium,or old in terms of stage of maturity),soil condition in terms of soil compaction,and soil erosion linked to the effects of trampling by grazing animals along transects(hereafter referred to as transect)to water source point.The total sample size for grass species was 160 plots.The grassland ecosystem condition,herbaceous biomass,and grass nutritional content were used as response variables linked to transect from water source point.The effects of transect on grassland ecosystem condition scores and grass nutritional content were analyzed using the analysis of variance(ANOVA).Results:Grassland condition factors like grass composition,basal cover,litter cover,age distribution of dominant grasses,and soil condition were significantly(P<0.05)higher for the furthest transect to water source point than nearest transect.Out of the 28 identified herbaceous species,grasses accounted for 64.3%of the herbaceous community.Within grass species,about 55.6%were highly desirable in terms of palatability and grazing value(as most palatable species are susceptible to heavy grazing intensity).The results showed a significantly(P<0.05)higher proportion of perennial grasses at the furthest transect to water source point than nearest transect.The dry matter yield at the furthest transect(TD4)and third transect(TD3)were significantly(P<0.05)higher than the nearest transect to water source point(i.e.,the first transect(TD1)and second transect(TD2)).Ash,neutral detergent fiber,acid detergent fiber,and acid detergent lignin contents of Cynodon dactylon,Sporobolus pyramidalis,and Digitaria ternata were significantly(P<0.05)higher at the furthest transect to water source point than nearest transect.Grazing intensity had no significant effect on the crude protein content of Cynodon dactylon and Sporobolus pyramidalis at different transects.Conclusions:The results showed that the furthest transect to water source point were in good condition.Grass biomass production and the nutritional contents of grasses were higher for the furthest transect to water source point.The results suggested that increased grazing intensity towards water source point greatly reduced the abundance of desirable perennial grasses and the sustainability of grassland for livestock production.
