浅谈吴昌硕先生的花鸟画

写意画作为中国美术的重要组成部分,它能完整地传达中国美术的精神实质和内涵,再现中国人的美术发展观。吴昌硕先生的写意花鸟画,深受徐渭和八大山人影响,加之他书法、篆刻功底深厚,把书法、篆刻的行笔、运刀及章法、体势融入绘画,形成了富有金石味的独特画风,在中国绘画史上,开创了文人画的新纪元。     

桎梏与枷锁:反思高中英语教学中的“花盆效应”

"花盆效应"是教育生态学的基本原理之一。通过对赣州市某3所高中随机抽取的高一至高三年级共167位学生问卷调查,显示目前赣州市高中英语教育基本处于"封闭在校园里,局限在课堂上,定位在课本中,考核在分数间"状态,"课内学习与课外运用"失衡,学习方式和学习效果的"花盆效应"明显。在新课标的指导下,要打破花盆的"桎梏",既要学校管理者先进的管理理念和创新教育思想为学生提供足够的"阳光雨露",又要英语教师营造和谐课堂环境、确保社会关联、挖掘教材张力和组织课外活动等"悉心浇灌"。     

Antioxidant activity and protective effect of Clitoria ternatea flower extract on testicular damage induced by ketoconazole in rats

Background

Ketoconazole (KET), an antifungal drug, has adverse effects on the male reproductive system. Pre-treatments with antioxidant plant against testicular damage induced by KET are required. The flowers of Clitoria ternatea (CT) are proven to have hepatoprotective potential. However, the protective effect on KET-induced testicular damage has not been reported.

Objective

To investigate the protective effect of CT flower extracts with antioxidant activity on male reproductive parameters including sperm concentration, serum testosterone level, histopathology of the testis, and testicular tyrosine phosphorylation levels in rats induced with KET.

Methods

The antioxidant activity of CT flower extracts was determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assays. Male rats were treated with CT flower extracts (10, 50, or 100 mg/kg BW) or distilled water via a gastric tube for 28 d (preventive period: Days 1–21) and induced by KET (100 mg/kg BW) via intraperitoneal injection for 7 d (induction period: Days 22–28). After the experiment, all animals were examined for the weights of the testis, epididymis plus vas deferens and seminal vesicle, serum testosterone levels, sperm concentration, histological structures and diameter of testis, and testicular tyrosine phosphorylation levels by immunoblotting.

Results

The CT flower extracts had capabilities for DPPH scavenging and high reducing power. At 100 mg/kg BW, the extract had no toxic effects on the male reproductive system. Significantly, in CT+KET groups, CT flower extracts (50 and 100 mg/kg BW) alleviated the reduction of reproductive organ weight parameters, testosterone levels, and sperm concentration. In addition, CT flower extracts gave protection from testicular damage in KET-induced rats. Moreover, in the CT100+KET group, CT flower extracts significantly enhanced the expression of a testicular 50-kDa tyrosine phosphorylated protein compared with that of other groups.

Conclusions

C. ternatea flower extracts possessing antioxidant activity are not harmful to the male reproductive system and can protect against testicular damage in KET-induced rats.

浅识黄宾虹的花鸟画

黄宾虹是现代山水画大师,同时擅长花鸟绘画。他的山水画气势雄浑,富有神韵;花鸟画则淡、静、古、雅,意多闲逸。在其花鸟画中,所取物象不求形似,注重传达物象的内在美感和情趣。他强调书法入画,并把太极图的内在哲学原理巧妙地纳入绘画理法之中,在石涛的"一画"说之后提出了"一点"说,使中国画的笔法认识论重新上了一个新台阶。
