The aqueous extract of leaf of Aegle marmelos (Bael) at the dose 50 mg/100 g body weight resulted a significant diminution in the activities of testicular key steroidogenic enzymes along with low levels of plasma testosterone and relative wet weights of sex organs in respect to control without any significant alteration in general body growth. Germ cells numbers in different generation at stage...

backgrounds: seminoma is frequently observed in human and canine testes especially in cryptorchids. canine and human seminomas are typically associated with leukocytic infiltration. objectives: we aimed to identify the type of lymphocytes that infiltrate to seminomas. methods: tumor infiltrating lymphocytes were evaluated by immunohistological techniques in 5 dogs with diffuse seminoma. routine...

Freshwater ecosystems are positioned at low levels in the landscape and receive large inputs of diverse plant-based detritus, a major source of energy for consumers in aquatic ecosystems. We conducted Þeld experiments in Urbana, IL to determine the independent and combined effects of leaves of common tree species including thenorthern redoak (Quercus rubraL.), sugarmaple (Acer saccharumMarshall...

Many studies have shown that exogenous abscisic acid (ABA) promotes leaf abscission and senescence. However, owing to a lack of genetic evidence, ABA function in plant senescence has not been clearly defined. Here, two-leaf early-senescence mutants (eas) that were screened by chlorophyll fluorescence imaging and named eas1-1 and eas1-2 showed high photosynthetic capacity in the early stage of p...

Characteristic features are: the leaf in T/S shows an epidermis of colourless, thickwalled, non-suberised cells, a band of photosynthetic and vascular tissue around the leaf perimeter (2+3), a central core of large thin-walled cells with contents staining pink-orange with KOH solution; yellow-green stomata and idioblasts containing bundles of calcium oxalate raphides (1), each up to 200μ long, ...

The objective of this study was the investigation of a potential influence of artichoke leaf extract (ALE) on the cell physiology and gene expression of phase I/II enzymes of human liver cells HepG2 and investigation on potential cell protective effects against ethanol-induced cell toxicity against HepG2 cells. Cell biological assays under in vitro conditions using HepG2 liver cells and investi...

neurotrauma is one of the main medical problems that affect considerable number of population especially young persons in all countries. neurotrauma not only is a serious threat for life but also creates various disabilities and consequently imposes large costs to society. following central nervous system (cns) injury, tissue damage occurs via primary and secondary mechanisms. despite many atte...

salvia genus belongs to lamiaceae family that was used in ancient and its application in culinary, flavor cosmetics, food and drinking industries is important. in the present study to assess compatibility of salvia sclarea to field condition and determine its potential for medicinal and ornamental applications, wild seed were cultured in pots. after initial growth, seedlings at 6-8 leaf stage t...

Guava (Psidium guajava L.), is adapted to an extensive range of soils, however, its development is strongly affected by salinity. Environmental stresses are of the major and influential factors in the amount of secondary metabolites, especially phenolic compounds present in plants. The purpose of this investigation was to study the leaf antioxidant and flavonoid contents (catechin, quercetin an...

In order to study of the effect of priming and salinity on physiological and chemical characteristics of wheat(Triticum aestivum L.), an experiment was carried out at the Experimental Farm of Shiraz University. Results showedthat primed plants significantly reduced its gas exchanges by accelerating senescence under a series of salt stress,which became more serious along with the increasing of s...
