Leptin treatment ameliorates anxiety in ob/ob obese mice

We investigated whether or not administered leptin influences anxiety-like behavior in ob/ob mice. Repeated intraperitoneal administrations of leptin were continued for 5 days. Anxiety was assessed in the standard elevated plus maze. Body weight was measured daily. Repeated administrations of leptin significantly increased the percentage of the total number of entries in the open arms and the number of total entries. The body weight was significantly reduced by 13.2% after treatment. Leptin treatment ameliorated not only obesity but also anxiety in ob/ob mice. Our results indicate that the treatment of obesity may lead to the solution of psychological problems.

Development of colostrum MAF and its clinical application

Recently, immunotherapy has emerged as a new and appealing strategy for cancer treatment and various other acute and chronic diseases. Essential components of the natural immune system-phagocytic cells called macrophages-multiply in response to an infection in the body. The use of a macrophage activating therapy, such as macrophage activating factor (MAF), has extensive applications for treating numerous diseases by activating the natural macrophages of the body to stimulate the immune system. The aim of this review is to provide insight into the features and clinical efficacy of a new type of macrophage-activating factor derived from colostrum, called colostrum MAF.
