ABSTRACT
Mandibular osteomyelitis in a patient with psoriasis is an uncommonly clinical manifestation while there is an increasing number of reports and studies on involvements of stomatology in psoriasis, especially the death of a patient via or not via Allogeneicbone marrow transplantation has never been reported.To review the management and possible mechanisms in pathogenesis and treatment of psoriasis, as well as the relative involvements between stomatology and psoriasis the typical case with pictures and files is reviewed and literature is collected.Wekeepthe knowledge that psoriasis is either a primary keratinocyte disorder or an immunocyte-mediated chronic skin inflammatorydisease while bone marrow is under suspected for immunopathogenesis. More association of stomatologic conditions with psoriasis is emerging. Conclusively, allogeneicBMT and new knowledge are worth to be stressed by both stomatological and dermatological doctors. Further insights of this kind of auto immunologic disease are under its developing.
ABSTRACT
<p><b>OBJECTIVE</b>To determine the effects of ginsenosides Rb1(GSRb1) on learning and memory and expression of somatostatin (SS) in the hippocampus and the frontal cortex in rat model of sleep deprivation (SD).</p><p><b>METHODS</b>Rats were randomized into groups of SD 2 d, SD 4 d, SD 6 d, and SD 0 d, while each group was sub-divided into GSRb1 group and normal saline (NS) sub-groups. Rats were intraperitoneal administered with 30 mg/(kg*d) of GSRb1 or NS for 7 d, then the learning and memory abilities were examined by measuring average swimming speed and mean escape latency using Morris maze.Expression of somatostatin was detected with immunohistochemical method and image analysis in the hippocampus and the frontal cortex.</p><p><b>RESULTS</b>Compared with SD 0 d rats, SD rats exhibited significant decrease in the average swimming speed and increase in the escape latency (P <0.01). The expression of somatostatin in the hippocampus was decreased significantly in SD 2 d, SD 4 d and SD 6 d rats (P<0.05). However, decrease was only observed in SD 4 d and SD 6 d rats in the frontal cortex (P <0.05). Parallel comparison between NS control and GSRb1 treated rats demonstrated that rats treated with GSRb1 in each subgroup exhibited faster swimming speed and shorter escape latency (P <0.05). Meanwhile, the expression of somatostatin was increased in SD 2 d, SD 4 d and SD 6 d rats in the hippocampus and in SD 4 d and SD 6 d rats in the frontal cortex (P <0.05), respectively.</p><p><b>CONCLUSION</b>GSRb1 enhances the expression of somatostatin in sleep deprivation rats and subsequently may improve learning and memory abilities of rats.</p>
