Evidence for differential effects of 8-OH-DPAT on male and female rats in the Anxiety/Defense Test Battery

The Proxemics/Activity test and the Eat/Drink test, two components of the Anxiety/Defense Test Battery, were developed to measure defensive reactions to situations associated with a natural predator (cat). In the present studies the behavioral effects of 8-OH-DPAT treatment (0.01–1.0 mg/kg, SC) were entirely consistent with anxiety/fear reduction. These effects included an increase in time spent near the cat compartment, and a complimentary decrease in time spent farthest from this compartment, together with an increase in transits and locomote behavior. 8-OH-DPAT (1.0 mg/kg) also increased eat frequencies and durations (highly preferred food) both during and following cat presentation, without influencing drinking. This finding is discussed with reference to previous findings with 8-OH-DPAT in studies assessing both food intake and anxiolysis. Interestingly, 8-OH-DPAT was more potent in a majority of its effects in female subjects, a finding consistent with recent neurochemical data. These findings provide important behavioral evidence for a sexual differentiation in 5-HT function, and support the case for greater emphasis on female subjects in animal models of anxiety.Supported by NIH MH42803 and RCMI Grants RR03061 and RR01825

Modulation of infection-induced inflammation and locomotive deficit and longevity in senescence-accelerated mice-prone (SAMP8) model by the oligomerized polyphenol Oligonol.

Oligonol is produced from the oligomerization of polyphenols (typically proanthocyanidin from a variety of fruits such as lychees, grapes, apples, persimmons, etc.) and contains catechin-type monomers and oligomers of proanthocyanidins. The ability of Oligonol to affect infection-dependent eye inflammation, locomotion and longevity in senescence-accelerated prone mice (SAMP8) (a model of senescence acceleration and geriatric disorders with increased oxidative stress and neuronal deficit) was investigated. Oligonol (60mg/kg) significantly modulated the extent of inflammation scores in the eye of SAMP8 mice. Examination of the mice indicated infection with mouse hepatitis virus and pinworm (Syphacia obvelata) in both males and females and with the intestinal protozoa (trichomonad) in males. A comparison of the two groups (using log-rank test) and the difference in the mean life span between groups (using Student's t-test) indicated significant differences in survival (p=0.043) and the mean life span (p=0.033) in male SAMP8 mice. Oligonol increased the mean life span and this was statistically significant. In the open-field locomotive test, the 7-week-old SAMP8 mice crossed more than 40 partitioned lines in 1min. At 48-week-old control untreated male SAMP8 crossed 2 lines. The Oligonol-treated 48-week-old male SAMP8 mice crossed 17 lines however. The improved locomotive activity was statistically significant even after 36weeks in the Oligonol-treated male SAMP8 but this was not the case throughout the time course of the study in the Oligonol-treated female SAMP8. Thus Oligonol treatment to SAMP8 mice modulated the severity of infection-dependent inflammation, prolonged life-span and significantly improved locomotive activity indicating potential benefit to aging-associated diseases such as Alzheimer's or Parkinson's diseases. This presents potential for further research to define infection-dependent inflammation associated with degenerative conditions and the molecular mechanism of dietary antioxidant protection.

Quantitative autoradiography of 5-HT1D and 5-HT1E binding sites labelled by [H]5-HT, in frontal cortex and the hippocampal region of the human brain

In human cortex and hippocampus area, [³H]5-HT (5 nM) labels 5-HT_1A, 5-HT_1D and 5-HT_1E sites. After masking 5-HT_1A receptors by 0.1 μM 8-OH-DPAT, the binding displaced by 0.1 μM 5-CT presumably represented 5-HT_1D sites and the remaining binding 5-HT_1E sites. In frontal cortex, 5-HT_1A receptors represented the main binding in layers II and VI and a lower fraction on other layers. 5-HT_1D and 5-HT_1E sites, were more homogeneously distributed in layers II to VI (21–34% of specific [³H]5-HT binding). 5-HT_1E sites were of similar affinities (K_D close to 6–8 nM) in the cortical layers II to VI. In CA1 field of hippocampus, (pyramidal layer, stratum radiatum, molecular layer), CA2 and dentate gyrus, 5-HT_1A receptors represented the major fraction, 5-HT_1D sites a significant fraction and 5-HT_1E a minor fraction of the specific [³H]5-HT binding. In CA3–CA4 fields, 5-HT_1A receptors were less densely present, 5-HT_1D sites were predominant and 5-HT_1E sites represented a significant fraction (27%). The highest densities of 5-HT_1E sites have been measured in subiculum, where 5-HT_1A, 5-HT_1D, and 5-HT_1E binding sites were equally represented and in entorhinal cortex where 5-HT_1E sites represented the major binding in layer III. They were also present in layers II and IV (29 and 24%) and, to a lesser extent, in layers V and VI. 5-HT_1A sites were predominant in layer VI, II and V and were less abundant in other layers. 5-HT_1D were homogeneously present in layers II, III, IV and were present in low amounts in other layers. No 5-HT_1E were detected in choroid plexus, where [³H]5-HT was dramatically reduced by mesulergine (5-HT_2C receptors). No significant displacement of [³H]5-HT by mesulergine was measured in other structures.
