Changes of Calbindin D-28k- and c-fos-immunoreactivities in the superior collicuclus after Eye Enucleation. Objective and methods: Calcium-binding proteins (CBPs) play an important role in the protection, differentiation and reorganization of the central nervous system. The effects of neonatal retinal deafferentation on a CBPs, calbindin D-28k were examined immunohistochemically in the superficial layer of the rat superior colliculus. Also early gene familly c-fos was examined to evaluate the neuronal characteristics in the superior colliculus after monocular enucleation. Results: On the experimental side of superior colliculus, the number of calbindin D-28k-immunoreactive (IR) cells was reduced (77.4% compared to control), but not fibers. Appearance of c-fos-like immunoreactivity was represented much more in the ipsilateral superior colliculus than contralateral side within 24h after eye enucleation. Conclusion: These results suggest that the changes of retinotectal projection may alter the expressional pattern of calbindin D-28k and c-fos expression.

As one of use and processing expansion methods of Barley, we investigated the digestive properties of puffed barley. Using α-amyase as a starch digestive enzyme, we experimented in artifical gastric juice (pH 1.2) and artificial intestinal juice(pH 6.8). And we analyzed the structure of puffed barley compared with that of raw barley by X-Ray Diffractometer. The following results were obtained. 1. In artificial gastric juice (not contained α-amylase), the hydrolysis of starch by acid was very weak. In α-amylase added artificial intestinal juice, the starch-digestive power of puffed barley increased about three times of rawbarley, one and half to two times of boiled barley. 2. From X-Ray Analysis, the crystallization degree of raw barley was 27.5%, but that of puffed barley was 9.1% In conclusion, it was thought that the starch-digestive power of puffed barley increased by the considerable destruction of the micelle structure of starch when barley was puffed.

Background: Superior colliculus is a part of midbrain, and participates in the visual reflexes, It receives afferent fibers from optic nerve, visual cortex, and spinotectal tract. After optic deprivation, the microscopic structure of the superior colliculus changed. Calcium-binding proteins (CBPs) Play an important role in the neuronal protection, differentiation and reorganization of the central nervous system, Objectives and Methods: The effects of neonatal retinal deafferentation on a CBPs, calbindm D-28k (CB), Parvalbumin (PB) and calretimn (CR), and the existence of colocalization between the CBPs were examined immunohistochemically in the rat superior colliculus. Results: On the experimental (contralateral to enucleation) side of superior colliculus, the number of CB-immunoreactive (IR) cells was reduced (77.4% compared to control), but not fibers. The number of PB-IR neurons and fibers was also reduced on the experimental side (88.5% compared to control), In the other hand, the CR-IR cells were dramatically increased (642% compared to control), but CR-IR fibers were markedly decreased on the experimental side. The colocalization between CB-CR and PV-CR was rarely observed in the superior colliculus Conclusion: These results suggest that the changes of retinotectal projection may alter the expressional pattern of CBPs in different manners; relatively stable in CB- and PV-IR neurons and plastic in CR-IR neurons.

This study is aiming at improving the Environmental Conservation Value Assessment Map (ECVAM) of National Land in Korea. The ECVAM items are composed of legal and environmental/ecological assessments. A popular method applied to ECVAM is an overlay environmental/ecological assessment items. The purpose of this study is to offer complementary items of the ECVAM by examining assessment items. In this study we assessed the ECVAM by five methods. Method 1 is Grade 1 areas of each administrative district; Method 2 is comparing overlapped areas of each assessment items Grade 1, 2 and permission of each assessment items duplication; Method 3 is Grade 1, 2 areas by only singular assessment items; Method 4 is Grade 1 areas only of Method 2; and Method 5 is Grade 2 areas only of Method 2. Method 1 showed Seoul and other metropolitan cities revealed a large proportion of Grade I regions by the legal assessment items. Gang won-Do, showed a large proportion of Grade I regions by the environmental/ecological assessment item. Method 2 showed 93.4 % of diameter Grade II (standard for stability); forest diameter item accounted for 99.9 % by Method 3, Method 4 showed 95.7 % of forest diameter, and forest density accounted for 66.4 % by Method 5. This study contributes to reduce the complexity in the process of manufacturing ECVAM of National Land, and to raise the flexibility in the process of managing and updating this map.

The calyceal diverticulum is a cystic cavity lined by a transitional epithelium, is encased within the renal substance, and is situated peripheral to a minor calyx, to which it is connected by a narrow channel. Both congenital and acquired factors have been suggested to explain the formation of a calyceal diverticulum. We experienced a case of a huge calyceal diverticulum that was newly developed after a renal injury. (J Korean Soc Traumatol 2009;22:264-268)
