Item Female infertility: role of vaginal hormonal cytology, endometrial biopsy and endocrinological evaluation.(2006-03-17) Afroz, Nishat; Singh, Mamta; Verma, Manju; Bansal, VandanaFemale infertility can be categorised into those who fail to ovulate (anovulatory infertility) because of some defect at hypothalamic-pituitary-ovarian axis and those who are ovulatory (ovulatory infertility), but are infertile because of some lesion present in genital tract. The role of vaginal hormonal cytology, endometrial biopsy and endocrinological evaluation in the detection of ovulation and various ovulatory dysfunction was studied in 42 infertile female patients. On the basis of cytological findings, of the 42 patients, 14 were found to be ovulatory, 26 anovulatory (which include 5 cases of atrophic changes) and 2 inconsistent due to inflammatory changes. Endometrial biopsy showed evidence of ovulation in 15, anovulation in 27 cases. Hormonal evaluation indicated some sort of endocrinological disorders in 15 patients, which may underlie anovulatory infertility in these patients, while results were within normal range in the rest 27 patients. Results of vaginal cytology and endometrial biopsy showed correlation in respect to ovulation in 93.33% of the cases.Item Induction of somatic embryogenesis in endangered butterfly ginger Hedychium coronarium J. Koenig.(2012-12) Verma, Manju; Bansal, Y KAn efficient protocol has been developed for regeneration of complete plants through somatic embryogenesis in H. coronarium. Creamish white, pale yellow and brown calli were obtained on MS medium supplemented with different concentrations of auxins [2, 4-Dichlorophenoxy acetic acid (2, 4-D), Indole-3 acetic acid (IAA) and 1-Naphthylacetic acid (NAA)] after 4 weeks. Creamy white calli developed on 0.5 mg L-1 2, 4-D turned embryogenic when subcultured on basal medium and produced small globular somatic embryos after 6 weeks. Further growth of somatic embryos required their transfer to medium containing 6-benzylaminopurine (BAP) or kinetin (KN). BAP was more effective than KN in promoting shoot proliferation. Maximum shoot length was obtained with 0.5 mg L-1 BAP whereas maximum shoot number was obtained with 1.0 mg L-1 BAP. The plantlets thus formed were successfully hardened, and transferred to sand-soil and farm yard manure (1:1:1) with 95% survival.Item Seroprevalence of hepatitis B infection during pregnancy and risk of perinatal transmission.(2011-03) Dwivedi, Manisha; Misra, Sri Prakash; Misra, Vatsala; Pandey, Arvind; Pant, Sanjay; Singh, Rita; Verma, ManjuObjectives To investigate the seroprevalence of hepatitis B surface antigen (HBsAg) in pregnant women and possible risk factors for perinatal hepatitis B virus (HBV) transmission. Methods Four thousand pregnant women were evaluated using history, examination, and test for serum HBsAg using commercial enzyme immunoassay kits. For HBsAg positive women, liver function tests and a test for hepatitis B e antigen (HBeAg) was done. HBV DNA analysis was done by polymerase chain reaction (PCR). Results Of 4,000 women studied, 37 (0.9%) tested positive for HBsAg. Of these 37 women, 6 (16%) presented with acute hepatitis and 31 (84%) were asymptomatic. The highest HBsAg positivity rate was seen in the age group of 21– 25 years (1.15%) followed by 26–30 years (0.86%). Assessment of risk factors revealed history of tattooing in 29/37 (78.4%) women. HBeAg was positive in 21 of 37 (56.8%) women. Of the 16 HBeAg negative women, 5 were positive for HBV DNA and anti-HBe antibody, 6 had only anti-HBe antibody and 5 had neither HBV DNA nor anti-HBe. Vertical transmission was seen in 65% (13/20) of babies born to mothers who were positive for HBeAg and HBV DNA. In contrast, it was only 9.1% (1/11) for babies born to mothers who were negative for both HBeAg and HBV DNA. Of the 25 babies delivered vaginally, 15 (60%) developed vertical transmission. None of the four babies delivered by elective cesarean section had evidence of vertical transmission. Conclusions Seroprevalence of HBsAg in antenatal women was found to be 0.9%. HBe-antigen and HBV DNA positivity was associated with a higher chance of vertical transmission
