The objective of the present invention is to provide a process for simple and efficient preparation of an intermediate compound to synthesize a gadolinium complex having a substituent for improving a retention property in blood time and specificity to an intended organ. The objective of the present invention is also to provide an intermediate compound produced by the said production process. The process for preparation of the diethylenetriaminepentaacetic acid derivative (I):
wherein R 1 to R 5 are independently C 1-6 alkyl groups; comprising the steps of: reacting a diethylenetriaminepentaacetic acid pentaester with a halogenated ally compound in an aprotic solvent; removing the excess halogenated ally compound (III); and reacting a reaction product of the diethylenetriaminepentaacetic acid pentaester and the halogenated ally compound with a base in a solvent.

[Problem to be solved] To kill bacteria with ultraviolet light that can effectively kill bacteria with ultraviolet light and to suppress bacteria increase due to photoreactivation after disinfection. [Means to solve the problem] Bacteria in water 9 exposed outdoors are effectively killed with ultraviolet (UV) light by suppressing post-treatment increase in the bacteria population due to photoreactivation. The apparatus shines UV light on the water 9 to kill bacteria and has UV light emitting diodes (LEDs) 1 that emit UVA light with a primary emission peak of 320nm-400nm. The antibacterial action of the UVA light emitted by the UV LEDs 1 prevents proliferation of bacteria in the disinfected water 9 due to photoreactivation.

The present invention provides a method for predicting the risk of acquiring influenza, which comprises measuring the ratio of anti-influenza IgA to the total IgA in a specimen collected from a subject.
摘要:
The present invention provides a method of fabricating a light emitting diode, which comprises the steps of forming a compound semiconductor layer on a substrate, the compound semiconductor layer including a lower semiconductor layer, an active layer and an upper semiconductor layer; and scratching a surface of the substrate by rubbing the substrate with an abrasive. According to the present invention, the abrasive is used to rub and scratch the surface of the light emitting diode, thereby making it possible to cause the light emitted from the active layer to effectively exit to the outside. Therefore, the light extraction efficiency of the light emitting diode can be improved.
