The distribution and the infestation rates of metacercariae in fishes from the Kum-Ho river were observed from June 1965 to August l967. The results obtained are as follows: The Fourteen kinds of metacercariae; Exorchis oviformis, Metorchis orientalis, Cyathocotyle species, Metacercaria hasegawai, Clonorchis sinensis, Metagonimus species, Pseudexorchis major, Echinochasmus species, Centrocestus species, Prosorhpynchus species, and four kinds of unidentified species, A, B, C and D were detected from 12 kinds of fishes. Clonorchis sinensis, Metagonimus species, Echinochasmus species, and Centrocestus species of the detected 14 kinds of flukes were noted to be parasited in man; Metorchis orientalis and Cyathocotyle species in avian species; and Exorchis ovifomis and Pseudexorchis major in wels, but the definite host of the other 6 kinds of flukes were not identified. Exorchis oviformis was found in 64.5 percent, of all kinds of fishes, Cyathocotyle species in 36.8 percent of 7 kinds of fishes, Metacercaria hasegawai in 36.3 percent of 8 kinds, Clonorchis sinensis in 95.0 percent of 6 kinds and Metagonimus species in 47.9 percent of 10 kinds. Concerning the infested rates of metacercaria and the length of fishes, Exorchis oviformis and Clonorchis sinensis showed increased rate by the length of fishes but the rest of fishes showed no relationship between them. The infested degree of metacercaria of Clonorchis sinensis was highest in Pseudorasbora parva with 34.3 parasites per cubic cm of flesh, of Exorchis oviformis in Carassius carassius with 7.3, of Cyathocotyle species in Acheilognathus with 6.0, and of Metacercaria hasegawai in Pseudogobio esocinus with 5.7 but Prosorhpynchus etc. were very few in all kinds of fishes. The infested rates of metacercaria in the four kinds of fishes, Pseudorasbora parva, Pungtungia herzi, Pseudogobio esocinus and Gnathopogon coreanus seemed not to be influenced by season, Spring and Autumn. In the infested rates of metacercariae by parts of fishes, Exorchis oviformis was chiefly infested in scales and fins; Metorchis orientalis, Cyathocotyle species, Clonorchis sinensis, Pseudexorchis major, Centrocestus species and Prosorhpynchus ecinatus were chiefly infested in muscle; Metacercaria hasegawai in muscle and fins; Metagonimus species chiefly in scales; and Echinochasmus chiefly in gills.

The congenital diverticulum of ventricle is a rare cardiac malformation arising from the left or right ventricle, the former being more common. Ventricular diverticulum is usually associated with other anomalies including intracardiac, midline thoracic, diaphragmatic and abdominal wall defect. The authors experienced a case of congenital diverticulum of left ventricle in nine month-old female infant. Left Blolock-Taussig shunt operation was done and total correction will be done later. Thereafter we presented a case with brief review of the related literatures.

Polypeptide antigen as isolated from adult worms of Clonorchis sinensis by means of diluted HCl-extraction method. Preliminary intradermal examination with those polypeptide antigen(CPT) were performed on patients of clonorchiasis, paragonimiasis and metagonimiasis and the result of the intradermal test with CPT antigen were compared with those of Clonorchis protein fraction(CPF) and Veronal buffer saline extraction (VBS) antigen. The result of the examination were summerized as follows: When 0.05 ml (1 microgram) of CPT was injected intradermally, the positive intradermal reaction appeared in 42.7 per cent (37 of 82) on the patients of clonorchiasis. The sizes of the wheal and erythema with CPT antigen was smaller than that of CPF and VBS antigen. Intradermal reaction with CPT antigen was carried out for other parasitic diseases, such as paragonimiasis and metagonimiasis. The result indicated that CPT antigen may be showed no cross reactions. Clonorchiasis pateints who with negative reaction to CPT antigen, reacted negatively to CPF and VBS antigens.

The Parasitological investigation on the encysted metacercariae in brackish water fish, Tribolodon taczanowskii, in the downstream of Hyungsan river which is located in Kyungpook Province of Korea, were carried out serially and the following results were obtained. Metacercariae of Pseudexorchis major were found in six fishes(15.8 per cent ) out of 38 examined. Parasitic frequencies of the encysted metacercaria of Psedexorchis major in Tribolodon taczanowskii were 15.8 per cent (6 out of 38) in the scale, 10.5 per cent (4 out of 38) in the fin, 13.2 per cent (5 out of 38) in the gill, 10.5 per cent (4 out of 38) in the oral cavity and 7.9 per cent (3 out of 38) in the flesh. The worms were identified as Pseudexorchis major (Hasegawa, 1935) Yamaguti, 1938 by morphological studies on the metacercariae, excysted metacercariae, adults and eggs, and compared with prereported Pseudexorchis species.

The expression of c-fos and c-jun in the brain of the rat after capsaicin treatment was investigated by in situ hybridization, dot blot hybridization and immunocytochemical methods. Adult male Sprague-Dawley rats[200g] were used for this study. The first set of rats received a single subcutaneous injection of capsaicin[50mg/Kg] dissolved in 10% Tween-80 and 10% ethanol in saline. The rats were decapitated 1, 3, 5, 10, 24, 72 hours and 1 week after capsaicin treatment. The control set of rats were treated with saline instead of capsaicin. In situ hybridization and dot blot hybridization were carried out. O1igonucleotide probe complimentary to c-fos mRNA sequences were used for this study and labeling of oligonucleotides was accomplished using the DNA tailing kit. The expression of c-fos mRNA on the nucleus of neurons in in situ hybridization was observed throughout the brain, and was especially abundant in the olfactory cortex, nucleus of diagonal band of Broca, habenular nuclei, periaqueductal gray, parabrachial nucleus, entopeduncular nucleus, ventral posterolateral nucleus of the thalamus and cerebellum. Compared to the control rats, c-fos mRNA were increased 24 hours after capsaicin injection and gradually decreased after 72 hours, returning to the normal control level 1 week after capsaicin injection. c-fos mRNA was detected only 1 week after capsaicin injection in the various areas of the brain. The fos protein-like immunoreactivity was initially somewhat decreased at 24 hours, but increased at 72 hours and reactions was maximally observed at 1 week after capsaicin treatment. But Jun protein immunoreactivity was not increased, on the contrary, it was even decreased both in numbers of reactive cells and immunoreactivity 1 week after capsaicin injection. From the above results, c-fos gene expression was pronounced in the nucleus concerned with pain, olfaction and taste such as VPL nucleus of the thalamus, olfactory cortex and parabrachial nucleus, in the limbic system concerned with stress and emotion such as nucleus of diagonal band of Broca, periaqueductal gray and habenular nucleus, in the structure concerned with somatic motor function such as entopeduncular nucleus and cerebellum. Also, the c-fos gene was activated by the capsaicin early in the course of effects, then the fos protein increased as a results of c-fos activation. On the other hand, c-jun did not respond to capsaicin treatment early in the course, but Jun protein decreased late in the course of capsaicin effects.
