    Notes: Abstract The purpose of this study was to evaluate congenital anastomoses between hepatic arteries demonstrated on angiography in ten patients and to correlate the anastomosis with types of hepatic arterial anatomy. We evaluated the types of the hepatic arterial anatomy based on Michels’ classification for 720 patients and compared the anatomic types between the patients with the anastomoses (ten patients) and without the anastomoses (710 patients). The diameter of the anastomoses ranged from 1.5 to 3.0 mm (mean, 2.4 mm). Five anastomoses were classified as tortuous type and five as straight type. Based on Michels’ classification for types of hepatic arterial anatomy, eight (80%) of ten patients with the congenital anastomoses were classified as type III (replaced right hepatic artery from superior mesenteric artery). The remaining two patients were classified as type IV (replaced right hepatic artery from superior mesenteric artery and replaced left hepatic artery from left gastric artery) and type VIIIa (replaced right hepatic artery from superior mesenteric artery and accessory left hepatic artery from left gastric artery). Eight (16%) of 48 patients who were classified as type III have the anastomoses. In conclusion, the congenital anastomoses were observed especially in patients with replaced right hepatic artery from superior mesenteric artery.

    Notes: Abstract The hepatic falciform ligament artery (HFLA) was evaluated by angiography and also by dissections. Based on the findings, the mechanism of the post-chemoembolization skin rash was studied. A total of 340 liver cirrhosis patients who underwent hepatic artery chemoembolization for hepatocellular carcinoma were reviewed in terms of the angiographic incidence of the HFLA, variations in its origin, and the incidence of skin rash. The HFLA was demonstrated in 26 (7.6%) of the 340 patients on angiography. Two HFLAs were observed in one patient. The origin was the middle hepatic artery (A4) in 16 cases, the superior branch of the middle hepatic artery in three, the inferior branch of the middle hepatic artery in two, the inferior branch of the left hepatic artery (A3) in three, and the confluence of A3 and A4 in three cases. There were no patients who developed post-chemoembolization skin rash. Two cadavers were dissected to investigate the anastomosis between the HFLA and the subcutaneous artery. Two different anastomoses were found: (1) direct and (2) via the ensiform branch of the internal thoracic artery. These were located at the lower and upper part of the falciform ligament, respectively. The distribution of a chemotherapeutic agent through these anastomoses is the likely cause of post-chemoembolization skin rash. If prophylactic embolization of the proximal portion of the HFLA using a metallic coil is performed, the skin rash will be prevented.

    Description / Table of Contents: Résumé L'artère du ligament falciforme hépatique (ALFH) fut étudiée par des angiographies et des dissections. D'après les résultats, le mécanisme d'un rash cutané après chimio-embolisation est discuté. Un total de 340 patients présentant une cirrhose hépatique ayant eu une chimio-embolisation de l'artère hépatique pour un carcinome hépato-cellulaire fut revu en fonction de l'incidence angiographie de l'ALFH, les variations d'origine de l'ALFH, et l'incidence d'un rash cutané. L'ALFH fut objectivée angiographiquement chez 26 (7,6%) des 340 patients. Deux ALFH furent objectivées chez un patient. L'origine des ALFH était située sur l'artère hépatique moyenne (A4) dans 16 cas, la branche supérieure de l'artère hépatique moyenne dans 3 cas, la branche inférieure de l'artère hépatique moyenne dans 2 cas, la branche inférieure de l'artère hépatique gauche (A3) dans 3 cas, et la confluence A3 et A4 dans 3 cas. Aucun patient ne développa un rash cutané après chimio-embolisation. Deux cadavres furent disséqués pour étudier les anastomoses entre l'ALFH et les artères sous-cutanées. Deux types d'anastomoses entre l'ALFH et des artères sous-cutanées furent individualisés directement et par l'intermédiaire de l'artère xiphoïde et de l'artère thoracique interne. Celles-ci étaient respectivement situées à la partie inférieure et à la partie supérieure du ligament falciforme. La distribution de l'agent chimiothérapique par ces anastomoses est vraisemblablement la cause des rash cutanés après chimio-embolisation. Dans le cas d'une embolisation prophylactique de la portion proximale de l'ALFH par utilisation d'un coil métallique le rash cutané pourrait être prévenu.

    Notes: Summary The activity of the pure 10R (=natural) and 10S enantiomers of juvenile hormone III (JH III) was determined in 3 different bioassays, and the relative binding affinity of the 2 enantiomers to the haemolymph JH-binding protein of the cockroachNauphoeta cinerea was measured. In theGalleria wax test, a local morphogenetic assay, the 10R enantiomer was 5240 times more active than, the 10S enantiomer, 1Galleria unit corresponding to 0.42 pg of 10R-JH III as compared to 2.2 ng for 10S-JH III. In a systemic morphogenetic assay with the cockroachNauphoeta cinerea 380 times less 10R enantiomer was necessary in order to induce detectable juvenilisation (58 ng 10R and 22 μg 10S) and in a systemic gonadotropic assay withNauphoeta cinerea 255 times less 10R was needed to induce vitellogenin synthesis in 50% of the insects (6.7 ng 10R and 1710 ng 10S). In the JH-binding protein assay 10R-JH III had an affinity for the JH-binding protein (lipophorin) which was approximately 46 times higher than that of 10S-JH III.

    Notes: Abstract. Background: Although a specific syndrome of the uterus didelphys, obstructive hemivagina, and ipsilateral renal agenesis had been reported in gynecologic literatures, it is not familiar to radiologists. We introduce this syndrome with radiological, especially MR findings. Methods: Imaging findings and medical records of seven patients with this syndrome were retrospectively reviewed. Results: MR clearly demonstrated uterus didelphys with obstructed hemivagina in six of the seven patients. A remaining one showed uterus didelphys with left-sided hematometra and hematosalpinx who had undergone vaginal septum incision prior to the MR. We could also recognize ipsilateral renal agenesis in all five patients, in whom renal areas were examined on MR. After vaginal septum resection, symptoms disappeared in six patients. We could observe the disappearance of the obstructive complications with MR in three patients. Conclusions: MR can do much for the early diagnosis and the prevention against further complications of this condition because it can demonstrate the müllerian duct anomaly complicated with obstructed hemivagina in detail and even ipsilateral renal agenesis.

    Notes: Summary Carbon particles enhance hemopoiesis in irradiated mice. Serum from carbon-treated mice stimulated macrophage colony formation, and inhibited granulocyte colony formation. The finding suggests that carbon-treatment modulates the hemopoietic environment through the monocyte-macrophage system.

    Notes: Abstract A female-specific protein from the hemolymph, and a related ovarian protein were identified in the Pacific oyster Crassostrea gigas using immunological procedures. The latter protein was isolated from ovarian extract by a combination of precipitation in distilled water, ammonium sulfate fractionation, hydroxylapatite chromatography and gel filtration on a Sepharose 6B column, and was identified as a macromolecular glycolipoprotein of ∼500 kD; sodium dodecylsulfate polyacrylamide gel electrophoresis, under reducing conditions, revealed seven heterogeneous polypeptides. Using a specific antiserum against purified protein, we also examined the immunohistochemical distribution of the protein at light- and electron-microscopic levels. Light microscopy revealed its presence in the oocytes, and electron microscopy identified it in yolk granules and the vitelline coat of the oocytes. These results indicate that the purified protein is a vitellin-like protein. Since no organ other than the ovary reacted with the antiserum, it is probable that the protein is produced inside the ovary, probably autosynthetically by oocytes.

    Notes: Abstract The distribution and abundance of Japanese common squid [Todarodes pacificus (Steenstrup, 1880)] paralarvae off southern Kyushu Island near the Kuroshio were examined in relation to water types in the region. Surveys were conducted in 1996 and 1997 using paired, 70 cm diameter Bongo nets. Temperature–salinity plots from 0, 50 and 100 m depths were used to assign sampling stations to three water types: inshore, mixing and Kuroshio. In total, 4103 T. pacificus paralarvae were collected at 59 of 72 stations. Catch densities at positive stations ranged between 8 and 4282 ind./50 m2 sea surface area. Catches during both years were highest in mixing waters, followed by inshore and Kuroshio waters. Total catches were highest just north of the oceanographic front at the inshore edge of the Kuroshio and declined with increasing distance away from the front. Catches of paralarvae ≤1.0 mm mantle length also peaked near the front. In both years, ≥85% of all paralarvae and ≥69% of those ≤1.0 mm mantle length occurred less than 25 km from the front. We conclude that most spawning off southwest Kyushu occurs near the frontal zone, where Kuroshio and inshore waters meet.

    Notes: Abstract Matsushima Bay, one of the richest oyster-culture areas in Japan, is subject to heavy artificial eutrophication, mainly from the inflow of city and factory sewages. The physiological activity in the oyster Crassostrea gigas in hanging cultures (i.e., suspended in wire-mesh cages) in this embayment declines markedly with progressive development of the gonads; this decline in activity coincides with eutrophication-induced accumulation of fatty material in the epithelia of the digestive organs; the oyster is thereby forced to depend on these accumulated fats for respiratory substrates in order to maintain its increased physiological needs. However, the fats are inefficient energy sources for the oyster and hence, during each spawning season, 50% mortality occurs. In addition, such phenomena as overmaturation of the gonad and disturbance of the lipid and steroid metabolism seem to accelerate this mass mortality. On the basis of the results, the author has compiled a schematic diagram which illustrates the possible causes of mass mortality among C. gigas in an eutrophic environment such as Matsushima Bay.
