Aims: The effects of exogenously applied salicylic acid (SA) on gas exchange characteristics, photosynthetic pigments and chloroplast ultrastructure were investigated in gerbera at their reproductive stage under salt-stressed conditions.
 Methodology: A pot experiment was conducted glasshouse conditions the Zhejiang University, Hangzhou, China, (30° N/120° E) between February 2008 March 20...

Abstract In this work, the responses of Arabidopsis thaliana (L.) Heynh to trans -aconitic acid (TAA) were investigated. A. was grown in presence TAA a concentration range 400–1200 µM for 7 or 15 days. Changes morphoanatomy, cellular ultrastructure, and micromorphology roots evaluated by light transmission electron (TEM) microscopy. At concentrations below 1000 µM, reduced length primary roots,...

The purpose of this study was to investigate the effects ejaculatory duct obstruction (EDO) on contractile efficacy, smooth muscle ultrastructure, and α1A M3 receptors rat seminal vesicles (SVs). A total 48 male rats, aged 14-15 weeks, were randomly divided into three groups, namely, control, complete EDO, partial EDO. SV tissues collected at 4 8 weeks postoperatively for further experiments. R...

background: maternally administered opiates such as morphine represent a serious human health problem. opioid abuse may have unfavorable effects on reproductive organs. objective: the present study evaluates on the effects of morphine on structure and ultrastructure of uterus in balb/c mice. materials and methods: forty balb/c pregnant mice were divided into four groups: two experimental (i and...
