Objective:To investigate the anti-inflammatory and analgesic effects of the ethanol extract of leaves of Helianthus annus L.(***) in acclimatized Wistar ***:It was undertaken using the albumin induced paw edema model of inflammation as well as both the hotplate and tail immersion analgesic test *** of the extract tested in experimental rats were 0.5 g/kg,2 g/kg and 4 g/kg while negative and positive control rats received distilled water and indomethacin ***:It was shown that treatment with the tested doses of the extract effectively inhibited paw edema induced by egg *** effect was comparable if not better than the observations made in rats treated with 10 mg/kg of indomethacin *** with the extract was also observed to have significantly increased the mean tolerance time of rats to thermal noxious stimuli compared to control animals that had distilled water and appeared to be more effective than 10 mg/kg of indomethacin ***: These observations confirmed the presence of a strong anti-inflammatory and anti-noiciceptive activity in the ethanol extract of the leaves of *** and therefore validated the folkloric use of the leaves of this plant in treatment of pro-inflammatory,post traumatic situations.

Objective:To evaluate the effects of ethanol extract of leaves of Helianthus annus(***) on the fecundity of Wistar ***:Forty(20 male and 20 female) Wistar rats,grouped into control,ethanol extract treated rats and untreated,were used for the *** rats had 0.5 g/kg of ethanol extract orally for 2 weeks;control rats had 5%alcoholic water(solvent);and untreated rats had their normal feed and clean drinking *** treatment,the animals were sub-grouped into 5 mating groups to observe the coital frequency,pregnancy rate and average number of pups per group in ***:The results showed that coital frequency was unaffected by the extract treatment but pregnancy rate and number of pups per rat and per group were reduced significantly in groupsⅡ,ⅢandⅣcompared to those of groupⅠandⅤrats which were not treated with the ethanol extract of leaves of ***:The histodegenerative in the gonads reportedly induced by this ethanol extract in previous studies may be responsible for the reduced fecundity observed in treated adult rats.

Drip irrigated sunflower intercropping

引用

American Journal of Plant Sciences 2015年第11期6卷 1816-1821页

作者： Abel Henrique Santos Gomes Lucia Helena Garófalo Chaves Hugo Orlando Carvallo Guerra Federal University of Campina Grande Campina Grande Brazil

One of the difficulties in the implementation of agroenergy’s cropping is the growing area competition with subsistence crops. Few studies have been conducted to show the efficiency of intercropping between plants of energy’s potential with cultures of economic sustainability. The objective of this study was to evaluate the effectiveness of intercropping sunflower cultivars with corn and beans, in the initial growth under localized irrigation. The experiment was conducted at the end of the year 2012, in an area of 950 m2, located in the Campus II-UEPB, Lagoa Seca, Paraíba. The irrigation system was managed based on the Reference Evapotranspiration (ETo), calculated by the Penmann-Monteith Method with data obtained locally. The experimental design was a randomized blocks factorial (2 × 4) × 3, with treatments combining two varieties of sunflower in four plantation systems: single or isolated, intercropped with maize, with bean and with caupi. Each plot consisted of four rows of sunflowers in spacing 0.3 × 0.7 m and length of 5 m, interspersed with rows of beans or corn, except in the isolated system. The central rows of sunflowers were used to measure the following growth characteristics: plant height, stem diameter, number of leaves and leaf área. Data were subjected to analysis of variance by F test and the means compared by Tukey test at 5% probability. The diversification of sunflower varieties promoted differences in initial growth, regardless of the cropping system. There was significant effect at 15 DAS, where the sunflower variety “Advanta CF101” had higher plants than the variety “Hélio 253” at 40 DAS;the variety “Hélio 253” had a stem diameter greater than the “Advanta CF101”.

采用HKG(HCl-KOH-Giemsa)法对内葵杂3号三交种染色体进行了C-分带研究和分析。结果表明:每条染色体至少都有一条C-分带,染色体组共有62条C-分带,以中间带和着丝点带为主,中间带主要分布在染色体短臂上;C-分带强弱差异明显,其中46条强带,16条弱带。Giemsa C-分带带型公式为:2n=2x=34=8I++3T++5I+I+T++4C+2CI+4CI++3CI++I+T++CT++2CT+。每条染色体都显示出显著的带纹特征,因此,利用Giemsa C-分带方法可以将向日葵的每条染色体区分开。
