1. Female MR ("anxious") and MNRA ("non-anxious") Maudsley rats were tested in the CSD behavioral conflict paradigm (anxiety-like measure) and also in the FST paradigm (depression-like measure). 2. As expected, MNRA rats accepted significantly more shocks in the CSD paradigm than did MR rats (i.e., MNRA rats were less "anxious"), MNRA rats also exhibited significantly less immobility in the FST procedure (i.e., MNRA rats were less easily made "depressed"). 3. When the data were pooled across the two strains, there was a significant correlation between CSD and FST behavioral scores; however, there was no significant correlation between these measures when the data from the two strains were evaluated separately. Multiple regression (independent variables of rat strain and CSD score, dependent variable of FST score) revealed a significant effect of rat strain, but not CSD score, on FST behavior. 4. The relationship of these findings to the apparent relationship between anxiety and depression in humans is discussed.

This study was carried out to evaluate the preventive and curative effects of Pilose antler against osteoporosis due to kidney deficiency, and investigate its potential mechanism of action. A model of osteoporosis due to kidney deficiency was established in rats using bilateral ovariectomy. Pilose antler polypeptide (PAP), Pilose antler polysaccharide (PAP'), and their mixture (PAP+PAP') were separately administered to the rats for 12 weeks, with progynova and xianlingubao tablets (XLGB) as the positive control groups.

Background: In early spinal cord injury (SCI), glutamate receptors, including N-methyl-d-aspartate (NMDA) receptors (NMDARs), are over-stimulated by excessively released glutamate. The enhanced activity of NMDARs may cause cell death by overloading calcium (Ca) into cells based on their high permeability to Ca. Studies in SCI animals have shown that treatment with electro-acupuncture (EA) is able to reduce cell death and to improve functional recovery.

This study tested the hypothesis that circulating microparticles (MPs) exacerbated vascular wall (VW) remodeling after endothelial denudation by 0.014 wire in a rat model. Adult male Sprague Dawley rats (n = 40) were equally categorized into group 1 [sham-control (SC); 3.

We evaluated the effect of a dipeptide anxiolytic GB-115 (N-phenyl-hexanoyl-glycyl-L-tryptophan amide, neuropeptide cholecystokinin-4 analogue with antagonistic activity) on alcohol motivation in rats, which was formed over 12 months. High-emotionality MR rats were more sensitive to the anxiolytic effect of ethanol in the conflict situation test than low-emotionality MNRA rats.
