为了研究健康人T细胞库中是否存在G1特异性T细胞 ,我们应用重组人软骨抗原凝集原G1为抗原 (rG1) ,采用国际标准半有限稀释建系法 ,从 4名正常人外周血中建立了 11株rG1特异性T细胞系。 4名健康供者的rG1特异性T细胞系出现频率分别为 0 6 / 10 6(RP )、 0 5 / 10 6(AC )、 1 6 / 10 6(YZ )和 2 0 / 10 6(JY ) ,平均为 1 1± 0 5 / 10 6。远远低于类风湿性关节炎病人外周血rG1特异性自身反应性T细胞。所有T细胞系与rG1及WT和PPD共同培养以观察其特异性反应性 ,结果发现所建立的 11株T细胞系对人软骨抗原凝集素G1区具有良好的特异性。本研究结果提示正常人外周血中确有rG1特异性T细胞系 ,但是出现频率远远低于类风湿性关节炎病人 (另文报道 )。

Drug-Seeking Behavior Is Significantly Attenuated in Nutritionally Supplemented Cocaine Withdrawn Sprague-Dawley Rats

引用

Journal of Behavioral and Brain Science 2021年第7期11卷 143-156页

作者： Lauriann Young annice Webber-Waugh Karen Thaxter Physiology Section Department of Basic Medical Sciences The University of the West Indies (UWI) Mona Jamaica

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 Conclusion: Drug-seeking behavior that persisted during cocaine withdrawal was significantly diminished in the nutritionally supplemented.

Virgin Coconut Oil Improved Discriminative Learning and Working Memory in Aging Cycling and Non-Cycling Female Sprague-Dawley Rats Supporting Its Beneficial Effect in Retarding Age-Related Cognitive Decline

引用

Advances in Aging Research 2021年第5期10卷 97-112页

作者： Lauriann Young Brittany Smith annice Webber-Waugh Karen Thaxter Physiology Section Department of Basic Medical Sciences The University of the West Indies (UWI) Mona Jamaica

Aim: Beneficial effects of virgin coconut oil (VCO) consumption to improve cognition in menopausal females remain inconclusive. This study examined the effect of VCO supplementation in aging cycling and non-cycling rodents to assess its impact on cognition. Methods: Sprague-Dawley rats (10 - 18 months) were randomly assigned to a supplemented VCO group (SVCO) that received oral doses of 1.42 mL/kg/day VCO (n = 10) and a non-supplemented (NVCO) group (n = 10). Their performance in a biased Y-maze discriminative learning paradigm was assessed over a 16-week period. Rats were initially allowed 3 minutes to explore the maze (habituated) and subsequently pre-trained in the non-preferred, white chamber to associate the presentation of a tone with a treat (reward).

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

引用

Journal of Behavioral and Brain Science 2017年第12期7卷 585-597页

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.
