Chromohysteroscopy—A new technique for endometrial biopsy in Abnormal Uterine Bleeding (AUB)

引用

Open Journal of Obstetrics and Gynecology 2013年第5期3卷 11-14页

作者： nisha singh Bharti singh Department of Obstetrics & Gynecology King George Medical University Lucknow India

Objective: To evaluate the role of chromohysteroscopy in improving diagnostic accuracy of endometrial biopsy in cases of AUB. Design: Cross sectional interventional study. Materials and Methods: This study was conducted on 60 women with AUB in Dept. of Obst. & Gyne at King George Medical University, Lucknow over a period of one year. All cases underwent diagnostic hysteroscopy followed by chromohysteroscopy using 2% methylene blue dye. Hysteroscopic guided biopsy was taken from stained and unstained areas followed by an endometrial aspiration biopsy from whole uterine cavity. The histopathology results of three samples were compared and analyzed in relation with staining pattern and type of AUB. Data analysis was done on SPSS version 15 of windows 2007. Results: Out of 60 cases, 11cases were found to have non hormonal pathology after chromohysterosopic biopsy. Eight (72.72%) cases were diagnosed by stained endometrial tissue, one (9.09%) by unstained tissue and three (27.27%) by endometrial aspiration. The diagnostic ability of stained tissue biopsy was significantly higher (p = 0.006) than unstained biopsy and endometrial aspiration. Conclusion: Chromohysteroscopy is a simple and effective technique for diagnosing endometrial pathology in cases of AUB.

Influence of Treatment of <i>Jatropha curcas</i>L. Leachates and Potassium on Growth and Phytochemical Constituents of Wheat (<i>Triticum aestivum</i>L.)

引用

American Journal of Plant Sciences 2013年第5期4卷 1134-1150页

作者： nisha singh Tomar R. M. Agarwal School of Studies in Botany Jiwaji University Gwalior India.

Jatropha curcas L. commonly known as “physic nut” is an exotic species that shows invasive characters. Plantation of Jatropha species is being undertaken at a large scale for biodiesel production. The plants defoliate their leaves twice a year and have been shown to possess certain antinutritional factors. Seeds of Jatropha are removed from mature dried fruits for oil extraction and ovary walls are discarded. For the present experiments leachates from sun dried leaves and ovary walls of Jatropha curcas L. were used for analyzing their possible allelopathic effects on the growth of wheat (Triticum aestivum L. cultivar, MP-4010). Leachate treatments result in slight decrease in growth in terms of plant height, leaf area, biomass, spike length and 100 seed weight of wheat and increase in total phenols, tannins, phytic acid and free amino acids. Results suggest that the leachates of leaf and ovary wall of Jatropha curcas are slightly inhibitory, however the impact does not last long. Nevertheless, continuous plantation may lead to accumulation of damaging constituents which reflects the need for further analysis and experimentation.
