  • Seasonal variation in fatty acid profiles was examined in the visceral mass and the posterior adductor muscle of the female pen shell, Atrina pectinata. Total percentages of saturated fatty acids were similar between the two organs, and there was not a prominent seasonal change in both tissues. While the percentages of highly unsaturated fatty acids (HUFAs) in the visceral mass were higher than those in the posterior adductor muscle, monounsaturated fatty acids (MUFAs) were high in the posterior adductor muscle. HUFA contents, especially in $20: 5\omega3$, $22: 5\omega3$ and $22: 6\omega3$, markedly decreased in September in the visceral mass, and this decrease was associated with a corresponding total MUFAs in the same organ. A similar pattern of change in September was noted in the posterior adductor muscle MUFAs and HUFAs. These results indicate that $20:\omega3$ and $22:\omega3$ HUFA changes in the visceral mass and posterior adductor muscle reflect the reproductive stages in pen shell.

  • Human toxocariasis is a zoonotic parasitic disease caused by the larva of toxocara canis or cati. It is one of the most commonly reported zoonotic helminth infection in the world. Human are infected mainly by the accidental ingestion of embryonated eggs due to the pica, geophagia, the consumption of contaminated raw vegetables and poor personal hygiene particularly in childhood. In adults, the consumption of raw meat from potential paratenic hosts e.g. chickens, lambs, rabbits and dogs is a major cause of human toxocariasis. The larva can reach various organs such as the liver, lung, brain, and eye by the hematogenous spread and cause visceral larva migrans. We experience a case of pulmonary infiltration with eosinophilia by visceral larva migrans after eating the raw liver and kidney of a dog.

  • Eryngium foetidum Linn. leaves (EF) are widely used in Thailand and many countries throughout Asia as a culinary seasoning and a traditional medicine. However, adverse effect of high dose consumption in long duration has not been evaluated. The aim of this study was to investigate chronic toxicity of EF in mice. Thirty-two ICR male mice were divided into 4 groups of 8 mice each. The mice were fed AIN-76 rodent diet, or AIN-76 rodent diet supplemented with ground freeze-dried EF at 0.8%, 1.6% and 3.2% that is equivalent to approximately 35, 73 and 155 times that of human consumption, respectively, at 97.5 percentile for a period of 24 weeks. At the end of experiment, the mice were euthanized and blood samples were collected for hematological and biochemical evaluations. Necropsy was performed while visceral organs such as lung, liver, kidneys, spleen etc. were collected, weighed and histopathologically examined. Blood urea nitrogen (BUN) results of mice in 1.6% and 3.2% EF diet groups were significantly higher than the BUN of control group. No significant difference was noted in other biochemical and hematological properties between the treatment groups and control; all results were within normal range. Histopathology of almost all visceral organs showed no significant changes. However, tubulonephrosis and chronic interstitial nephritis were observed in the groups treated with 1.6% and 3.2% EF diet. Body weight was reduced significantly at week 12 to week 20 when compared to the control group while relative kidney weights were significantly increased. In conclusion, the consumption of EF in diet at high doses illustrated the adverse effect on some biochemical parameters and histopathology in mice. Our findings suggested that EF daily consumption for 24 weeks, at higher doses than the 0.8% EF diet (35 times of human consumption), might cause adverse effect on kidney function in mice.

  • A new disease causing mass mortality of farmed snakehead (Channa arga) has emerged in Korea over the summer of 2005. The affected fish showed no specific external signs with the exception of a distended abdomen and hemorrhaging around the anus. After opening the abdomen, the visceral organs, liver, spleen and kidney, present numerous white nodular structures. Histopathological examination revealed these nodules to be evidence of granulomas in the visceral organs. A Gram-positive, filamentous bacterium was isolated from all of the affected fish. Development of primers for a genus-specific peR assay for Nocardia, following analysis of the sequences of the complete 16S rRNA genes from Nocardia spp. and non-Nocardia bacterial genes, allowed identification of the causative organism as Nocardia. This is the first report of a nocardial infection of fish in Korea.

  • Seasonal changes in biochemical composition of muscle, gonad-viceral, mass and whole body of the cultured ark shell, Scapharca broughtonii in the Gamag bay of Yeosu city were studied from December 2008 to November 2009 in relation to environmental condition and reproductive cycles. Average monthly water temperature in the winter was in the range of $7-12^{\circ}C$ and $20-25^{\circ}C$ in the summer, while the salinity fluctuated in the range of 30.1%-33.8‰ on the average. Seasonal fluctuation of the concentration of nutrient salt was the highest in September ($13.04{\mu}g/L$) with average annual concentration of $4.6{\mu}g/L$. The main spawning season of the ark shell was during the months of July and August, and the gonads were in inactive stage during the winter. The gonad-visceral mass contained lower amounts of proteins than the other body parts. The most marked changes in body composition were lipids and carbohydrates within the gonad-visceral mass, and protein for each of the organs was relatively consistent throughout the year. All the parts in the visceral sac displayed the highest changes during the gametogenic cycle while the contents of moisture and lipid within the visceral act displayed somewhat inverse relations with each other. Moisture content was the lowest during the inactive stage during which the lipid content is the highest. The lipid content was the lowest immediately following spawning with increase in the moisture content as the lipid is being consumed. Protein mass within the visceral sac was low in comparison to the muscle mass. It is deemed that carbohydrates, lipids and proteins in the visceral sac play the major role as the source of energy during the development process of the gonads, and used for maintenance of base metabolism when available food is scarce.

  • The proximate composition of viscera of six fish species viz., Catla catla, Labeo, rohita Cirrhina mrigala, Hypophthalmichthys molitrix, Ctenopharyngodon idella and Cyprinus carpio under the influence of artificial feed $(T_1)$, broiler manure $(T_2)$, buffalo manure $(T_3)$, N:P:K (25:25:0 $T_4$) and control pond $(T_5)$ has been studied on final harvest after the end of experimental period of one year. The overall comparison of six fish species under five different treatments showed that Cyprinus carpio remained the best for visceral total protein contents. The maximum visceral protein content was recorded in fishes under $T_2$ except Cirrhina mrigala, while the minimum under $T_5$. The comparison of five treatments showed that maximum (6.69) percentage of fat in viscera of fish was recorded under $T_2$, closely followed by $T_4$ while minimum (4.89) under the effect of $T_5$. Among the six fish species under five treatments Cyprinus carpio showed maximum accumulation/deposition of total fats in viscera.

  • To determine alteration of immune responses during visceral larva migrans (VLM) caused by Toxascaris leonina at several time points, we experimentally infected mice with embryonated eggs of T. leonina and measured T-helper (Th) cell-related serial cytokine production after infection. At day 5 post infection (PI), most larvae were detected from the lungs, spleen, intestine, and muscle. Expression of thymic stromal lymphopoietin (TSLP) and CCL11 (eotaxin) showed a significant increase in most infected organs, except the intestine. However, expression of the CXCL1 (Gro-${\alpha}$) gene was most highly enhanced in the intestine at day 14 PI. Th1-related cytokine secretion of splenocytes showed increases at day 28 PI, and the level showed a decrease at day 42 PI. Th2-related cytokine secretion of splenocytes also showed an increase after infection; in particular, IL-5 level showed a significant increase at day 14 PI, and the level showed a decrease at day 28 PI. However, levels of Th17-related cytokines, IL-6 and IL-17A, showed gradual increases until day 42 PI. In conclusion, Th1, Th2, and Th17-related cytokine production might be important in immune responses against T. leonina VLM in experimental mice.

  • The synergistic effect of conjugated linoleic acid (CLA) and $\gamma$-oryzanol (OZ) on the reduction of visceral and body fats was investigated in mice. Female ICR mice, 10 weeks of age, were acclimated for one week and then randomly divided into 5 treatment groups by body weights: Control (70 ${\mu}l$ olive oil + 30 ${\mu}l$ CLA), CLA-OZ 1 (70 ${\mu}l$ olive oil + 30 ${\mu}l$ CLA + OZ 0.5 mg), CLA-OZ 2 (70 ${\mu}l$ olive oil + 30 ${\mu}l$ CLA + OZ 1.0 mg), OZ (100 ${\mu}l$ olive oil + OZ 1.0 mg), and Olive oil (100 ${\mu}l$ olive oil). Samples were daily intubated, p.o., for 4 weeks. Food and water were ad libitum. Four weeks later, mice were sacrificed by neck dislocation, followed by measuring whole body weight, empty carcass weight (ECW), which is weight without organs and visceral fats, visceral fats, body fats and protein content. Mice treated with CLA (control) sample maintained significantly, p<0.05, lower whole body weight, ECW, visceral and body fats, relative to mice treated with olive oil sample, indicating that CLA reduces the visceral and body fats. The CLA-OZ 1 treatment significantly reduced, p<0.05, visceral and body fats as compared to OZ treatment, but not significantly different from control treatment.Meanwhile, CLA-OZ 2-treated mice maintained significantly, p<0.05, lower visceral and body fats than control and OZ-treated mice. Protein contents in mice were not affected by any other treatments. These results suggest that OZ enhanced the reduction of visceral and body fats in mice by CLA.

  • The chemical components, lipid class, and fatty acid composition of the viscera from male and female common squid, Todarodes pacificus, were examined to evaluate the possible utilization of the liver, reproductive organs, and gills. In male and female squid, the viscera comprise 21% and 27% of the body weight, respectively. The protein content of the viscera was slightly higher in females (17.7-19.5%) than in males (15.6-17.2%). This was especially marked in the female reproductive organs, while there was little difference in the gill. The liver contained the largest amounts of lipids (17.2-18.6%) and the levels were higher in males than in females (P<0.01). By contrast, the reproductive organs of females contained more lipids than did those of males (4.68% vs. 1.65%, p<0.01). The prominent non-polar lipid (NL) classes were triacylglycerol (51.9-55.4% of the NL content) and sterol ester (16.3-21.8%) in the liver, and free sterol (47.0-68.5%) and free fatty acids (31.5-41.2%) in the reproductive organs. However, there were no significant differences in the NL classes between sexes. The percentage of the most prominent phospholipid (PL) class, phosphatidylcholine (PC), was highest in the liver (78.1-79.6% of the PL content), and there was no significant difference between the sexes. By contrast, phosphatidylethanolamine (PE) was highest in the reproductive organs (33.4%), and was higher in males than in females (P<0.05). All the visceral organs contained 36.4-48.5% of n-3 polyunsaturated fatty acids (PUFA), such as docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). The DHA level was highest in female reproductive organs (32.3%), while EPA was high in male reproductive organs. These results demonstrate that the viscera of male and female common squid are a good source of DHA and EPA.
