In order to restrict an over-temperature-rising of a diesel particulate filter, an electronic control unit computes a flow rate of the exhaust gas flowing through the DPF so that temperature of the DPF is kept at a temperature in which the DPF can be regenerated. The hydraulic pressure control system includes a line pressure control means for controlling a line pressure supplied to one of the variable pulleys; and a speed ratio control pressure control means for controlling the line pressure as a speed ratio change pressure supplied to the other of the variable pulley according to a desired speed ratio. As a result of their MCH-receptor antagonistic activity the pharmaceutical compositions according to the invention are suitable for the treatment of metabolic disorders andor eating disorders, particularly obesity, bulimia, anorexia, hyperphagia, and diabetes.
