除了泌乳素瘤和肢端肥大症或库欣病等罕见的情况外,药物是用来控制分泌性疾病,而不是使肿瘤缩小(见后文).预计多巴胺激动剂(das)会导致泌乳素瘤缩小;卡麦角林(85% -90%)比溴隐亭(75%)更为有效.抗da的泌乳素瘤不能使泌乳素水平正常化(fail to normalize prolactin levels),不能缩小肿瘤或阻止肿瘤的生长(fail...
This method normalizes data to account for differences in morphology between plants. Water content can also be estimated using near infrared spectroscopy (NIRS). NIRS is based upon the absorption of NIR light by a sample. Light is absorbed in a wavelength region depending upon the composition of...
