The Effect of Dry Cleared Extract from Licorice Roots on the Learning of Ovariectomized Rats

The influence of chronic administration of a dry cleared extract of Glycyrrhiza glabra (DCEG) containing flavonoids on the behavioral status and learning of intact and ovariectomized adult female rats has been studied. The DCEG preparation was administered in low (0.5 mg/kg, i.p.) and high (5.0 mg/kg, i.p.) daily doses over a period of 14 days and the results were evaluated on the passive avoidance situation model and in the open field test. It was established that the chronic administration of DCEG in both low and high doses produced correction of the passive avoidance performance in ovariectomized female rats. The administration of DCEG in a low dose also positively influenced the structure of purposeful behavior of females with deficiency of estrogens. __________ Translated from Khimiko-Farmatsevticheskii Zhurnal, Vol. 39, No. 8, pp. 27 – 29, August, 2005.     

苏励教授治疗强直性脊柱炎经验介绍

苏励教授认为，脊柱在人体的位置处于皮里膜外，半表半里。强直性脊柱炎病在脊柱，故痰瘀之邪也盘踞在半表半里。治疗宜内清外透结合，在清里基础上外透，使邪有出路，从而清除盘踞在半表半里之邪实。并结合外治法以增加疗效。

慢性肝炎辨治五法

慢性肝炎（简称慢肝）属中医学“胁痛”、“黄疽”、“瘾积”等范畴。其病程长，疗效慢，且易反复发作。目前尚无特殊疗法。笔者通过研习有关文献，回顾长期临床验案，对慢性肝炎之证治略有心得，兹介绍如下。     

对诊断PADAM的游离睾酮指数的评估

目的 评价诊断中老年男子部分雄激素缺乏综合征（PADAM）的游离睾酮指数（FTI）.方法 对129例45岁以上健康男性的FTI进行年龄相关分析.以推算的游离睾酮（CFT）值为依据,对FTI进行有效性检验.结果 男子在中老年期FTI与增龄呈明显的负相关.FTI敏感性97.78%,特异性58.33%.结论 计算简单的FTI可用于PADAM病人的筛选和随访,尤其对70岁以上男子是血清FT较为有效的参数.     

Delayed expression of NADPH-diaphorase in rat brain after administration of the cholinotoxin AF64A

Administration of cholinotoxin etylcholine aziridinium (AF64A) into the brain selectively induces nonrever-sible cholinergic deficit. Wistar rats were injected intracerebroventricularly bilaterally with AF64A at doses of 1–3 nmol/ventricle. 28 days later the number of neurons survived was counted in dorsolateral, intermediate and medial groups of cells of the medial septum. AF64A induced a decrease in neuronal density and expression of cholineacetyl transferase at all doses used as well as in all regions studied. Brain sections were also stained for NADPH-diaphorase representing neuronal NO-synthase. Effects of AF64A on NADPH-diaphorase expression depended on the region studied. The number of NADPH-diaphorase-positive cells increased in the medial cellular group where more cholineacetly transferase-positive cells survived. In contrast, decrease in NADPH-diaphorase expression in the dorsolateral group of cells coincided with low level of cholineacetyltransferase-po-sitive neurons. The data presented suggest that in the AF64A-dependent model of neurodegeneration NO may play a neuroprotective function.
