    Notes: Abstract Floral volatiles of two introduced Oenothera species, Oe. glazioviana (= Oe. erythrosepala) and Oe. biennis, were chemically examined using the headspace method. As a result, linalool, one of the monoterpenes, was found to be the main constitutent of floral volatiles, with several other undetermined substances. Visual signals of these two Oenothera species were the same, with a strong UV-absorbent spot in the center of the corollas. Large nocturnal hawkmoth species such as Theretra japonica, Agrius convolvuli, and Deilephila elphenor lewisil are major pollinators for these two Oenothera species. An interplay between floral UV-absorbancy patterns as visual signals and floral volatiles released seems to be playing a significant role in pollinator attraction. Nectar utilization and the breeding system of Oe. glazioviana were also examined.

    Notes: Abstract This study was undertaken in order to determine whether the administration of nifedipine, a calcium channel blocker, could protect the liver from ischemic damage and to investigate its effect on the hepatic cellular energy status and cardio-vascular system after 60 minutes of hepatic ischemia in dogs. The ischemia was induced by temporarily clamping the portal vein and hepatic artery. One group of animals (n=17) received nifedipine (5 μg/kg body weight) intravenously 15 minutes before the induction of liver ischemia, which was continued at a dose of 0.2 μg/kg body weight/min throughout the ischemic period, and for an additional 30 minutes afterwards. Control dogs (n=16) were not given nifedipine and survival was observed over seven days. The survival rate was 83 per cent in the nifedipine treated animals and 0 per cent in the control animals. Serum glutamic oxaloacetic transaminase levels were greatly increased following ischemia, and they were significantly lowered with the nifedipine treatment. The hepatic energy charge decreased remarkably during the hepatic ischemia, however it increased gradually after declamping but did not returned to its preoperative value in either group until one hour later and then it was higher in the nifedipine treated animals than in the control animals. Cardiac index and portal venous blood flow ratio remained higher in the nifedipine treated animals than in the control animals, after the ischemic period. These results suggest that nifedipine may have a powerful cytoprotective effect and that the period of warm hepatic ischemia could be prolonged with its use.

    Notes: Abstract A 30 year old female was admitted with right upper abdominal pain and fever. Ultrasonography and computed tomography revealed a large cystic mass in the right lobe of the liver, and aspiration bacteriology was negative. A right hepatic lobectomy was performed for a suspected cystadenocarcinoma, however, the tumor was histologically diagnosed as a hemangiopericytoma with prominent venous invasion. The patient died within a short time of multiple pulmonary metastases. Primary hepatic hemangiopericytoma is extremely rare, and according to our research, this is only the 4th case reported in the literature.

    Notes: Abstract Fifteen patients with nonparasitic hepatic cysts underwent surgery to relieve abdominal complaints, at the First Surgical Department, Tokyo University Hospital between 1966 and 1989. Total removal of the cyst was carried out in 14 of the patients, while puncture and aspiration only were performed in the other patient in whom a cyst had ruptured spontaneously, after which hemoperitoneum was observed at emergency laparotomy. The size of the cysts varied from 7–19 cm with a mean of 12.4 cm. Histological study revealed a congenital cyst in 14 patients and a cystadenoma in one. The epithelium lining of the internal surface of the congenital cysts was highly atrophic and desolated and often disappeared. Examination of the cyst fluid revealed the same concentration of electrolytes as in the serum. Hepatic enzyme levels were usually lower than in the serum, but lactic dehydrogenase and aminotransferase levels were elevated in a few cases. Tumor marker levels of the cyst fluid were higher than those in the serum in four of five patients examined.

    Notes: Abstract Twenty-three patients with minute hepatocellular carcinoma, defined as a solitary lesion ≦2 cm, underwent hepatectomy at our institute during the 10 years between January, 1979 and December, 1988. Hepatitis B surface antigen was positive in 4 patients and the preoperative serum alpha-fetoprotein level was within the normal range in 7 patients and slightly elevated (20–200 ng/mL) in 14 patients. Liver cirrhosis was present in 16 patients and chronic hepatitis in 6 patients. The diagnosis was first suspected from the results of periodic examinations, including echography and the measurement of alpha-fetoprotein, in all except one patient. Minor hepatic resection was performed in 22 patients, and lobectomy in one patient in whom the tumor was located centrally in the liver. Three patients died of hepatic failure in hospital following surgery, and the survival rates of the other 20 patients at 1, 3, and 5 years were 90, 79, and 61 per cent, respectively. The prognostic factors that influenced long-term survival were investigated by comparing the survival curves. The only factor associated with a significant difference in survival was the severity of concomitant liver disease. Thus, severe cirrhosis is the main obstacle against the long-term survival of patients with minute hepatocellular carcinoma.

    Notes: Abstract Physical properties of newly developed synthetic absorbable sutures, “coated polyglactin 910”, were compared with findings in two conventional synthetic absorbable sutures. Clinical results of application in 108 cases in Japan (123 clinical cases in number of tissues approximated) were also evaluated. Our findings clearly indicate that coated polyglactin 910 sutures may well become the sutures of choice for various surgical applications.

    Notes: Abstract: Appendico-vesical fistula is a rare condition. In total, 109 cases, most secondary to appendicitis, have been reported in the English-language litera-ture. We report the first case, to our knowledge, of appendico-ileo-vesical fistula secondary to appendiceal diverticulitis. An enterovesical fistula was diagnosed by urine culture, cystoscopy, and computed tomography. The locations of enteric opening sites were demonstrated by barium enema and colonoscopy. Ileocecal resection and fistulectomy with primary reconstruction were performed. We believe that accurate pre- and intra-operative diagnosis is essential for cure. This case demonstrates the importance of barium enema and colonoscopic examinations in the diagnosis and treatment of complicated enterovesical fistula.

    Notes: Abstract We performed orthotopic liver transplantation in male Wistar rats and investigated the effect of superoxide dismutase (SOD) on the liver graft. Animals were divided into the four following experimental groups. Group I was an untreated control group, group II received oxygen, group III received SOD and group IV received both oxygen and SOD. The dose of SOD was 3 mg/kg which was injected intravenously into both donors and recipients during the operation. Oxygen was given through an oxygen inhaler to both donors and recipients during the operation. The preservation time of the liver graft ranged from 4 hours and 41 minutes to 5 hours and 40 minutes. The survival after liver transplantation was compared among groups I, II, III and IV. Group IV showed a significantly higher survival rate than groups I and II by two weeks after liver grafting, but there was no statistical difference in the survival rates between groups III and IV. These results indicate the beneficial effect of SOD on the rat liver graft and may implicate oxygen free radicals in the pathogenesis of ischemia/reperfusion injury in liver grafts.

    Notes: Abstract Anastomotic leakage is one of the most common complications of esophagectomy and, since Factor XIII is required for normal wound healing, we investigated the temporal changes in plasma Factor XIII following esophagectomy and hepatectomy. A control group of patients undergoing other abdominal operations was also studied. Factor XIII activity was determined before surgery and on postoperative days (POD) 1, 3, 7 and 14. The plasma levels of acute phase protein were also measured. The plasma Factor XIII activity decreased significantly in both the hepatectomy and control groups until POD 7, reaching the lowest level on POD 3. In contrast, the esophagectomy group showed significant decreases in Factor XIII levels throughout the postoperative study period, with a nadir with an average activity of 56 per cent on POD 7. Preoperative transferrin levels had a positive correlation with Factor XIII levels measured on POD 3 and there was also a positive significant correlation between Factor XIII activity and alpha 2-macroglobulin levels on POD 3. These results suggest that there is a marked and prolonged depression of plasma Factor XIII activity following esophagectomy which may be attributed to accelerated tissue demands, inadequate synthesis or increased degradation. Moreover, the severe and sustained decrease in Factor XIII activity may be related to poor wound healing after esophagectomy.

    Notes: Abstract We designed a simplified rat model to assess the effects of cyclosporine (CsA) on liver transplants. Auxiliary liver grafts consisting of 20 per cent of the whole liver were supplied with portal inflow and the bile was drained into the stomach. The cuff technique was used routinely for both end-to-end and end-to-side venous anastomoses. The host liver was totally deprived of portal inflow. Two inbred strains of rats, LEW and F344, were used for isograft (LEW→LEW) and allograft (F344→LEW). All survivors were killed at the end of the fourth week after transplantation. During four weeks, the isografts increased by 108 per cent in wet liver weight. Animals with allograft were treated with CsA given i.m., in a daily dose of 20 and 40 mg/kg for the rirst ten days post transplantation. The CsA-treated rats were free from parenchymal destruction of the allograft, as was characteristic of the allograft controls. The rats given CsA in the dose of 40 mg/kg showed a 173 per cent increase in the wet liver weight of the transplant, such being greater than allografts in rats on 20 mg/kg of CsA (100 per cent) and even than isografts. These results indicate that auxiliary partial liver grafts benifit from the use of CsA not only through suppression of allorejection but through a potential “hepatotrophic effect” of the agent.
