Among the distal anterior inferior cerebellar artery (AICA) aneurysms, a unique aneurysm at the meatal loop inside the internal auditory meatus is extremely rare. The authors report a case of surgically treated total intrameatal AICA aneurysm. A 62-year-old female patient presenting with sudden bursting headache and neck pain was transferred to our department. Computed tomography and digital subtraction angiography showed subarachnoid hemorrhage at the basal, prepontine cistern and an aneurysm of the distal anterior inferior cerebellar artery inside the internal auditory meatus. Surgery was performed by retrosigmoid craniotomy with unroofing of the internal auditory meatus. The aneurysm was identified between the seventh and eighth cranial nerve in the meatus and was removed from the canal and clipped with a small straight Sugita clip. After operation the patient experienced transient facial paresis and tinnitus but improved during follow up.

In Korea, new total energy-saving solution has planned to build test-bed in underground subway station. Breaking energy is one of the most energy saving method in railway, but it has not be fully used up for economical purpose. This paper demonstrates on energy saving technology application including breaking energy and heating energy to underground subway station. It also offer solution of optimization of power energy flow. Moreover, economic feasibility analysis performed for undergound test bed constuction.

Objectives: The present study was undergone to determine whether Glycyrrhizae Radix pharmacopuncture intravenous injection exerts beneficial effect against the ischemia-induced acute renal failure in rabbits. Methods: Rabbits were treated with Glycyrrhizae Radix pharmacopuncture via i.v., followed by renal ischemia/reperfusion. The fractional excretion of glucose and phosphate were measured and the malondialdehyde content was also determined. The morphological changes of cortical part of kidney also observed with light microscope. Results: Renal ischemia/reperfusion caused increase of the fractional excretion of glucose and phosphate in ischemia-induced animals, which was prevented by Radix Glycyrrhizae extract treatment. Ischemia/reperfusion increased lipid peroxidation, which was prevented and morphological changes also altered by Radix Glycyrrhizae pharmacopuncture administration. Conclusions: These results indicate that lipid peroxidation plays a critical role in ischemia-induced acute renal failure and Glycyrrhizae Radix pharmacopuncture exerts the protective effect against acute renal failure induced by renal ischemia/reperfusion.
