RESUMO

Hydrographic data collected from research cruises, bottom-anchored moorings, drifting Ice-Tethered Profilers, and satellite altimetry in the Beaufort Gyre region of the Arctic Ocean document an increase of more than 6,400 km3 of liquid freshwater content from 2003 to 2018: a 40% growth relative to the climatology of the 1970s. This fresh water accumulation is shown to result from persistent anticyclonic atmospheric wind forcing (1997-2018) accompanied by sea ice melt, a wind-forced redirection of Mackenzie River discharge from predominantly eastward to westward flow, and a contribution of low salinity waters of Pacific Ocean origin via Bering Strait. Despite significant uncertainties in the different observations, this study has demonstrated the synergistic value of having multiple diverse datasets to obtain a more comprehensive understanding of Beaufort Gyre freshwater content variability. For example, Beaufort Gyre Observational System (BGOS) surveys clearly show the interannual increase in freshwater content, but without satellite or Ice-Tethered Profiler measurements, it is not possible to resolve the seasonal cycle of freshwater content, which in fact is larger than the year-to-year variability, or the more subtle interannual variations.

RESUMO

We present a case of 83-year-old woman with pure red cell aplasia appearing eight months after thymo-thymectomy for an invasive thymoma. She underwent thymo-thymectomy for an invasive thymoma in July 1996. Preoperative examination revealed neither anemia nor hypogammaglobulinemia. About eight months after the operation, she was readmitted because of anemia and hypogammaglobulinemia. Bone marrow aspiration revealed absence of erythroblasts and chest CT revealed norecurrence of thymoma. Her anemia had responded to ciclosporin.

RESUMO

A 40-year old woman had experienced repeated spontaneous pneumothorax on the right side at the beginning of each menstrual period for one year. The level of serum CA125 was high at 60 ng/ml. Right thoracotomy revealed the presence of multiple darkly-pigmented spots and several pinhole like perforations near the central tendon of the diaphragm. The partial resection of the diaphragm was done, endometrial tissues were detected histologically. Tha patient has been asymptomatic after operation and the level of serum CA125 is normal.

RESUMO

We report a 69-yr-old female with a liver mass which, when surgically resected, was believed to be the spontaneous complete necrosis of hepatocellular carcinoma. The preoperative level of alpha-fetoprotein was high at 1050 ng/ml, and the mass was grossly an encapsulated nodular lesion with septa. Histologically, no viable tumor cells were demonstrated. The alpha-fetoprotein level decreased to a normal range. The postoperative course was uneventful, and the patient is alive and well 1 yr after surgery.

RESUMO

The aim of this study was to measure the tissue concentration of anti-cancer agents administered by arterial infusion. After the abdominal cavity was opened, 250 mg of 5-FU diluted in 20 ml saline was infused into the feeding artery in 16 patients with colonic cancer. After the affected lesion was resected, specimens were obtained at the tumor, at sites 5 and 10 cm from the center of the tumor, and at the adjacent nodes. The concentration of 5-FU was higher in the tumor and the adjacent lymph nodes than in the normal colon near the lesion. This suggests that 5-FU has a more favorable distribution profile in tumor tissue than in normal tissue. Patients with a high concentration of 5-FU in the tumor also demonstrated high levels in the other tissue. Blood flow volume and the length of time between the injection of 5-FU and harvest of the specimen may account for differences in the tissue concentration of the agent after administration of the same dose.

RESUMO

We experienced a case of the ruptured pseudoaneurysm of the aortic arch. Patient complained left anterior chest pain, back pain and hoarseness. Considering the past history of pulmonary tuberculosis, emergency operation was performed median sternotomy approach and using aortic occlusion balloon catheter method and selective cerebral perfusion. Woven dacron graft was anastomosis intraluminal aneurysm. Postoperative course was good. Median sternotomy approach and AOBC method were better than intercostal approach method, because of a little bleeding, short operative time and method.

RESUMO

The lactate dehydrogenase (LDH) and creatine phosphokinase (CPK) isoenzyme distributions in tissues of the ICR mouse, Wistar rat, guinea pig and golden hamster were analyzed by histoelectrophoresis. Tissues obtained were as follows: liver, pancreas, stomach, small intestine, heart, femoral muscle, uterus, kidney, spleen, lymph node, cerebrum, spinal cord and erythrocyte. Histoelectrophoresis was for the direct analysis of LDH and CPK isoenzymes in the tissues and had high practical value compared with previous tissue-extraction methods. In tissues of the mouse, guinea pig and golden hamster, LDH isoenzymes showed five bands. In the rat, LDH isoenzyme was separated into four fractions. CPK isoenzyme showed three bands; BB, MB and MM. In some tissues, the MM band was separated into two sub fractions.
