1Health risks associated with heavy metals in the drinking water of Swat,northern Pakistan显示文摘The concentrations of heavy metals such as Cd, Cr, Cu, Mn, Ni, Pb and Zn were investigated in drinking water sources(surface and groundwater) collected from Swat valley, Khyber Pakhtunkhwa, Pakistan. The potential health risks of heavy metals to the local population and their possible source apportionment were also studied. Heavy metal concentrations were analysed using atomic absorption spectrometer and compared with permissible limits set by Pakistan Environmental Protection Agency and World Health Organization. The concentrations of Cd, Cr, Ni and Pb were higher than their respective permissible limits, while Cu, Mn and Zn concentrations were observed within their respective limits. Health risk indicators such as chronic daily intake(CDI) and health risk index(HRI) were calculated for adults and children separately. CDIs and HRIs of heavy metals were found in the order of Cr > Mn >Ni > Zn > Cd > Cu > Pb and Cd > Ni > Mn > Cr > Cu > Pb > Zn, respectively. HRIs of selected heavy metals in the drinking water were less than 1, indicating no health risk to the local people. Multivariate and univariate statistical analyses showed that geologic and anthropogenic activities were the possible sources of water contamination with heavy metals in the study area.Kifayatullah Khan Yonglong Lu Hizbullah Khan Shahida Zakir Ihsanullah Sardar Khan Akbar Ali Khan Luo Wei Tieyu Wang 2013Journal of Environmental Sciences2013,25,10:12

3Carcinoma in situ in a 7 mm gallbladder polyp: Time to change current practice?显示文摘Detection of polypoid lesions of the gallbladder is increasing in conjunction with better imaging modalities. Accepted management of these lesions depends on their size and symptomatology. Polyps that are symptomatic and/or greater than 10 mm are generally removed, while smaller, asymptomatic polyps simply monitored. Here, a case of carcinoma-in-situ is presented in a 7 mm gallbladder polyp. A 25-year-old woman, who had undergone a routine cholecystectomy, was found to have an incidental 7 mm polyp containing carcinoma in situ. She had few to no risk factors to alert to her condition. There are few reported cases of cancer transformation in gallbladder polyps smaller than 10 mm reported in the literature. The overwhelming consensus, barring significant risk factors for cancer being present, is that such lesions should be monitored until they become symptomatic or develop signs suspicious for malignancy. In our patient's case this could have led to the possibility of missing a neoplastic lesion, which could then have gone on to develop invasive cancer. As gallbladder carcinoma is an aggressive cancer, this may have led to a tragic outcome.David Kasle Amir A Rahnemai-Azar Shahida Bibi Vinaya Gaduputi Brian F Gilchrist Daniel T Farkas 2015World Journal of Gastrointestinal Endoscopy2015,7,9:8
4Antifertility Activity of Hydroalcoholic Extract of Ocimum Basilicum Linn. Leaves on Female Wistar Rats显示文摘Objective To determine the effect of hydroalcoholic extract of Ocimum basilicum Linn. leaves on ovulation, implantation and maintenance of pregnancy in adult female cyclic Wistar rats. Methods Ocimum basilicum leaves extract (364 mg/kg and 624 mg/kg) was screened for its antiovulatory, antiimplantation and abortifacient activities. Vaginal smear of each rat was monitored daily during the 15-day treatment of the first experiment. Estimation of cholesterol in ovarian tissue and its histology was carried out to confirm its antiovulatory activity. In the second and third experiments, animals received treatment from 1st to 7th and 8th to 16th day of pregnancy, respectively. The number of implantations and litter size were determined through laparotomy on 10th and 20th day of pregnancy, respectively in two tests. The treated groups were compared with pain control. Results A significant increase in duration of estrus cycle and diestrus phase was observed (P<0.001). A significant decrease in ovarian weight and notable increase in ovarian tissue cholesterol level was also observed (P<0.001). Weight of uterus in treated group was found to be decreased. Histological report showed presence of large corpora lutea in ovarian parenchyma. Neither antiimplantation nor abortifacient effect was observed in rats treated with both the doses of extract. Conclusion Hydroalcoholic extract of Ocimum basilicum interferes normal ovulation by disrupting the estrus cycle and prolonging diestrus phase thus, has a potential of being developed into a female contraceptive.Alia Bilal Nasreen Jahan Ajij Ahmed Saima Naaz Bilal Shahida Habib 2013Journal of Reproduction and Contraception2013,24,1:2
