This study was undertaken to determine the present status of pesticide residues in breast milk from Punjab. A total of 127 breast milk samples were analyzed and pesticide residues were detected in 25 % of the milk samples. Residues of cyfluthrin, fenvalerate, cypermethrin, profenophos, γ-HCH, β-HCH, chlorpyriphos, monocrotophos, p,p′ DDE and phosalone were detected with mean levels of 63.04, 11.69, 3.63, 2.66, 2.64, 2.29, 1.91, 1.63, 0.56 and 0.29 ng g?1, respectively. Cyfluthrin was leading pesticide detected in breast milk contributing 31.28 % to the total residue load. It was observed that the residue levels were decreasing with increase in parity and age of mother and cyfluthrin had highest mean concentration of 90.63 ng g?1 in the first parity and 21.11 ng g?1 in youngest age group. Residue levels were higher in urban population than the rural population although, statistically non-significant difference was found between the two (p > 0.05). 相似文献

BACKGROUND: The goal of this study was to examine the role of ultrasonography in detecting axillary lymph node metastases in stage II breast cancer patients after induction chemotherapy (IC). METHODS: Of 172 consecutive patients with T1-3, N0-1, M0 breast cancer registered in a prospective IC trial, a subset of 130 evaluable patients were chosen, with (1) both physical and ultrasonographic examinations of the axilla before and after IC; (2) exactly four cycles of IC; (3) no presurgical radiation therapy; and (4) an axillary lymph node dissection. RESULTS: Before IC, 32 patients (25%) were negative for axillary involvement by both physical and ultrasonographic examinations. After IC, this number increased to 64 (49%). Of these, 31 (48%) were positive by pathology examination. In most cases, however, the residual tumor was minimal. CONCLUSIONS: Stage II breast cancer patients who were or became node negative by both ultrasonographic and physical examinations after IC had a 48% incidence of nodal metastases. Because the residual tumor was minimal, irradiation may be sufficient for adequate local control of the axilla. 相似文献
