Some enzymatic properties of the lipase extracted from rice bran were studied. The rate of free fatty acid formation as a function of incubation time was maximum after 30 min. at $35^{\circ}C$. The activation energy of the enzyme was 1.83 Kcal/mol and using a olive oil emulsion as substrate, the Km value was $0.8{\times}10^{-3}M$. The enzyme activity was more stimulated by calcium ion. Application of these enzymatic properties onto the effective utilization of rice bran and preservation of rice were discussed.

The feeding habits of olive flounder, Paralichthys olivaceus were studied using 126 specimens collected from coastal waters off Taean, Korea from April 2008 to March 2009. The total lengths of P. olivaceus ranged from 16.7 to 40.6 cm. P. olivaceus was a piscivore that consumed mainly fishes. The diet also included small quantities of shrimps, cephalopods, polychaetes and mysids. Although, P. olivaceus mainly consumed fishes of all size classes, some degree of change in diet composition was found; i.e. after fishes, smaller individuals fed more on shrimps, whereas larger individuals consumed more cephalopods.

Autometallography method with intraperitoneal injedlon of sodium selenite was employed to investigate the localization of somata of zinc enriched (ZEN) neurons in the medulla oblongata The distribution patterns of the labeled neurons were variable from rostral to caudal regions. The labeled cells by the method were found in Cl adrenaline cells, gigantocellular reticular nucleus, inferior olive, paragigantocellular nucleus, prepositus hypoglossal nucleus, raphe obscurus nucleus, and reticular nucleus regions.

The potential utility of injection media (sucrose, PEG, and liposome) was demonstrated for direct gene transfer into olive flounder (Paralichthys olivaceus) muscles. Based on the use of sucrose (final cone. 20%), PEG 8,000 (final cone. 10%) or liposome (twice us of DNA injected), the present injection strategy significantly improved the level of transgene expression as well as persistent duration of expression. The increased amounts of expression in DNA injection with sucrose, PEG, and liposome were as high as from 2.1 to 4.9-folds of conventional TE-based DNA injection. The best result was obtained from injections of liposome-encapsulated DNA in which the expression was detectable at least 32 days after injection when compared to only 8-16 days from TE-based injections.

Pseudolepidapedon kobayashii collected from the alimentary canal of the olive flounder, Paralichthys olivaceus, which were caught at the Chinhae Bay, was reported for the first time in Korea, and P. olivaceus was recorded as a new host for P. kobayshii. The morphological characteristics of P. kobayashii were described and compared with the other species in the genus.

The purpose of the present study was to determine whether the scuticocidal activity of olive flounder (Paralichthys olivaceus) head-kidney leucocytes can be enhanced by stimulation with polyinosine-polycytosine [poly (I:C)]. The growth of Miamiensis avidus was not affected by exposure to unstimulated or poly (I:C)-stimulated leucocytes alone, heat-inactivated immune serum alone, or unstimulated leucocytes plus heat-inactivated immune serum. However, leucocytes stimulated with poly (I:C) showed clearly high scuticocidal activity against M. avidus in the presence of heat-inactivated immune serum. Furthermore, numerous poly (I:C)-stimulated leucocytes occupied the surface of scuticociliates in the presence of the heat-inactivated immune serum, which led to lysis of scuticociliates. These results suggest that both of the stimulation of leukocytes and the immobilization of scuticociliates are necessary to kill scuticociliates by leukocytes.

Kudoa septempunctata have been reported as a causative agent for acute transient gastrointestinal troubles after eating raw olive flounder (Paralichthys olivaceus). It raised public health concerns and quarantine control in several countries. Quantitative evaluation on viability of K. septempunctata is crucial to develop effective chemotherapeutics against it. A cytometry using fluorescent stains was employed to assess effect of three compounds on viability of K. septempunctata. Epigallocatechin gallate reduced markedly viability of K. septempunctata at 0.5 mM or more, and damaged K. septempunctata spores by producing cracks.
