Objectives : This study was performed to investigate the effect of water extracts from Lagocephalus wheeled with several herbs(LW) on hyperlipemia and liver damage induced by alcohol. Methods : Except for the normal group, we fed rat on 25% alcohol for 55 days. And each extract was administrated for the same period. We measured the serum component in rat's blood, body weight and weight of liver. Results : At first, we observed effects of LW on hyperlipemia induced by alcohol. LW group didn't show significant increase of total cholesterol in comparison with those of the control group. LW group didn't show significant increase of HDL(High-Density lipoprotein) cholesterol in comparison with those of the control group. LW group showed significant decrease of triglyceride in comparison with those of the control group. LW group showed significant increase of body weight in comparison with those of the control group in 4weeks and 8weeks. LW group showed significant increase of liver weight in comparison with those of the control group. At second, we observed effects of LW on liver damage induced by alcohol. LW group showed significant decrease of ALP, GOT, GPT and LDH in comparison with those of the control group. Conclusions : Reviewing these experimental results, it appears that water extracts from Lagocephalus wheeleri with several herbs have pharmaceutical efficacy on hyperlipidemia and liver damage induced by alcohol. Therefore further additional study should be conducted to elucidate in depth the pharmaceutical efficacy of this.

To develop natural-tasting fish paste from the pufferfish Lagocephalus wheeleri, steamed pufferfish paste (SPP) was prepared and its optimal processing conditions, quality metrics, and shelf-life characteristics were examined. SPP was produced by thawing golden threadfin Nemipterus virgatus surimi (FA grade), then adding 10% unwashed pufferfish surimi (PS), 1.5% salt, 8.0% wheat starch, 0.25% calcium carbonate, 0.25% sugar, 0.75% sorbitol, 0.25% polyphosphate, and 12.0% pufferfish hot-water extract (Brix 10°). The meat was ground with a Stephan mixer, molded at low temperature (18℃, 10 h), vacuum packed in a laminated plastic film bag, heat treated with hot water (95℃, 50 min), and cooled. As the amount of PS added increased, the whiteness, gel strength, and shear strength of the SPP decreased slightly. However, the SPP folding test showed no deterioration in the texture. In the sensory evaluation, the SPP received a higher rating for taste, smell, and overall taste than commercial Japanese pufferfish Kamaboko. The total amino acid content of the SPP was 10,262.6 mg/100 g; the major amino acids were aspartic acid, glutamic acid, alanine, valine, leucine, lysine, and arginine. The free amino acid content was 133.0 mg/100 g; the major amino acids were taurine, glutamic acid, glycine, alanine, cystine, and lysine.

The toxicity of five species of puffer fish, Arothron firmamentum (Byeolbok), Lagocephalus gloveri (Heukmilbok), L. wheeleri (Eunmilbok), L. inermis (Minmilbok) and L. lunaris (Milbok), collected from fish markets in Korea, was determined using a mouse bioassay. In A. firmamentum, the proportion of toxic specimens containing >10 MU/g was 87.5% in the ovaries, and 10.0% in the skin; no toxicity was detected in the muscle, fin, liver, intestine and gallbladder using the mouse bioassay. The highest toxin levels were found to be 87 MU/g in the ovaries, and 13 MU/g in the skin. Toxic specimens containing >10 MU/g were not detected from samples taken from any of the organs in L. wheeleri and L. inermis. In L. gloveri, most specimens were found to be non-toxic, but toxin levels of 11-72 MU/g were detected from within the skin, fins, and intestines in one specimen. In L. lunaris, the proportion of toxic specimens was 50.0% in the ovaries, and 7.1% in the gallbladder; no toxicity was detected in the other organs by the mouse bioassay. The highest toxin levels were 75 MU/g in the ovaries, and 14 MU/g in the gallbladder. Therefore, the toxicities of edible muscle and skin in the five species of puffer fish marketed in Korea were found to be within acceptable levels for human consumption.

Indonesian Lagocephalus wheeleri ("White-milbog") and Chinese Fugu obscurus ("Hwang-bong") puffers were dissected into liver, intestine, ovary or testis, skin and muscle for assay of toxicity, Also, the toxins from the puffer liver were partially purified and analyzed. The frequency of toxic specimens for Lagocephalus wheeleri was 20, 40, 0 and 10%, in terms of liver, intestine, skin and muscle, respectively; and average toxicity was 5.5$\pm$0.9(Mean$\pm$S.E.), 11.8$\pm$4.2, 2.2$\pm$0.1 and 3.0$\pm$0.8 MU/g, respectively. All of Fugu obscurus specimens had toxicity ranging between 2 and 210 MU/g. The frequency of toxicity in intestine and ovary, both 100% was to be higher percentage tan that of other tissues. The toxinsgave two spots tetrodotoxin(TTX) and anhydro-tetrodotoxin(anh-TTX) on TLC. Also, the toxin of each puffer species showed two spots in electrophoresis. In HPLC analysis of Fugu obscurus, the toxins showed TTX, 4-epi-TTX and anh-TTX.epi-TTX and anh-TTX.

To identify the food component characteristics of seven edible pufferfishes (five wild pufferfishes including striped puffer Takifugu xanthopterus; eyespot puffer Takifugu chinensis; purple puffer Takifugu porphyreus; rough-backed puffer Lagocephalus wheeleri; and grass puffer Takifugu niphobles; and two cultured pufferfishes including yellow puffer Takifugu obscurus, and tiger puffer Takifugu rubripes) in Korea, the proximate, fatty/amino acid, chemical and taste compositions were investigated. The proximate compositions were not significantly different among the sampled pufferfishes, whereas grass puffer had lower moisture and crude lipid levels contents, and higher crude protein and ash contents than the other species. The total amino acid levels in wild and cultured pufferfishes were 14,941.6-16,427.9 mg/100 g, and the major amino acids were aspartic acid, glutamic acid, glycine, alanine, leucine, lysine and arginine. Regarding the fatty acid and mineral compositions, the major fatty acids included 22:6n-3, 16:0, 18:1n-9, 20:5n-3, 18:0, 20:4n-3, and 22:5n-3 in that order, and there was a little difference among the sampled pufferfishes. Grass puffer had a higher monoenes ratio, i.e., 16:1n-7 and 18:1n-9, and a lower polyenes ratio than the other pufferfishes. The main minerals detected K, P, Na, S and Ca. Regarding the taste-active compounds, the free amino acid contents of pufferfish extracts were 236.4-428.1 mg/100 g, consisting primarily of taurine, lysine, proline, glycine, alanine and arginine in that order. The amino nitrogen content of the pufferfishes was 84.5-156.4 mg/100 g, and there was a little difference among the species. As for taste intensity, the total taste value of the purple puffer was higher than that of the other pufferfishes.

Twenty seven species of pufferfishes (family Tetraodontidae) have been examined to find their generic characters based on olfactory organ, lateral line system, prickles, body form and color characters of specimens collected in 20 places along the coast of Korea from September, 1989 to July, 1994. Based on nostril shape, the genera of Takifugu, Lagocephalus, Plurancanthus, Spheoides and Feroxodon have two nostrils, and those of Ephippion and Canthigaster have a single nostril or nasal tentacle, while Boesernanichthys, Arothron and Chelonodon have no nostril. In the genera of Lagocephalus, Spheoides, Boesemanichthys, Arothron and Feroxodon have only a single well-developed lateral line on the body, in those of Takifugu and Plurancanthus usually have two lateral lines, and those of Chelonodon and Ephippion have two lateral lines merged on the caudal peduncle. Based on the lateral line system and olfactory organ, genus Canthigaster has different characters from the other genera of the family Tetraodontidae. In Ephippion guttifer, the prickles on the dorsal and lateral of the body are enormously enlarged into plates forming a partial carapace. Of the 22 species which have prickly spines, the genera, Lagocephalus, Takifugu stictonotus and Arothron Stellatus have the larger ventral pricklyy spines than the dorsal ones. In genera Lagocephalus most of the species have prickly spines that coverd both the back and belly, while L. inermis has no prickly spines.

Twenty seven species of pufferfishes (family Tetraoaontidae) have been examined to find their generic characters based on vertebrae and pterygiophore characters of specimens collected in 20 localities along the coast of Korea from March, 1991 to March, 1994. It was divided by 3 groups based on vertebrae number as follow : the genera Lagocephalus, Pleurancanthus, Spheoides, Arothron, Chelonoeon and Canthigaster have 17$\~$19 vertebrae, genera Ephippion, Boesemanichthys and Feroxodon have 20 vertebrae, and genus Takifugu have 19$\~$25 vertebrae, The number of vertebrae ranged from 17 to 25 with the maximum of 25 in Takifugu obscurus. The modal number of vertebrae in Lagocephalus is 17 (L. lunaris), 18 (L. inermis), and 19 (L. gloveri, L. wheeleri, L. larigatus), with the lower number more specialized. Paired neural spines appear at number of the 1st$\~$5th vertebrae in Takifugu pardalis, Takifugu obscurus and at number of the 1 st$\~$4 th vertebrae in the other species and genera. All of the species of Lagocephalus and Pleurancanthus have dorsal and ventral pterygiophores processes, and flat-shaped epural, while none of the abdominal vertebrae processes complete haemal arches. The neural and haemal spines of the last few caudal vertebrae aye shorter in Pleurancanthus than in the other genera, associated with the depressed caudal peduncle. The genus Canthigaster is distinguished the first pterygiophores of the dorsal and ventral fins is always much larger than the others genera. Based on the haemal arches and spines of the abdominal vertebrae, genus Canthigaster has different characters from the other genera of the family Tetraodontidae.

Ninety-six specimens of nine puffer fishes landed at a fish market of Pusan, Korea were assayed for anatomical distribution of toxicity. The puffers, Lagocephalus gloveri ('geommilbog'), Fugu rubripes rubripes ('jajubog'), Fugu rubripes chinesis ('geomjajubog'), Lagocephalus wheeleri ('hinmilbog') and Arothron firmamentum ('byeolbog'), were shown to be nontoxic in muscle and skin. However, toxicities in skins of four specimens of Lagocephalus gloveri and a specimen of Arothron firmamentum were more than 10MU/g In the puffer, Fugu xanthopterus ('ggachibog'), the skin showed to be weakly toxic as far as nine specimens out of 27 ones are concerned, and the muscle was nontoxic in all specimens. Meanwhile, it was noted that the puffer, Fugu vermicularis radiatus was found to be a toxic species, differing from the toxicity known so far. Their highest toxicities were 3,880, 1,191, 1,115, 219, 289, 5,620 and 753MU/g for liver, intestine, skin, muscle, testis, ovary and bile, respectively.

Twenty four species belonging to 10 genera and 4 families in the suborder Tetraodontoidei in Korea were reviewed and provisional keys to species, genera and families are provided. Among them available specimens of seventeen species in this taxa collected during 1986 to 1990 from Korean waters were examined and recorded on the morphometric characters, their body color and collection sites. And two species are reported for the first time to Korea with their descriptions and figures : Lagocephallus gloveri Abe et Tabeta, 1983 and L. wheeleri Abe,Tabeta et Kitahama, 1984. Taki/ugu chiηensis Abe, previously recorded from Pusan, Korea as paratype locality but not included in the list of Chyung, 1977, is listed in the present paper with the new korean name, "Chambok". Many of this taxa are also distributed throughout the waters of China and Japan. But it is found that the distribution of three species of genus Takifugu are restricted only to the west coast of Korea as well as to the adjacent waters of China in the Yellow Sea ; T. obscurus, T. flavidus and T. basilevskianus. Taxonomy and distribution of this taxa were discussed with references to the information obtained so far.
