[Clinical study of lumbar spinal canal stenosis on 70 operated cases --clinical symptoms, pathogenesis, operative method, postoperative results].

In surgical treatment of lumbar spinal canal stenosis, the stenotic area related to the clinical symptoms was determined and the stenotic form and stenotic factors in this stenotic area were estimated before operation. The most appropriate decompression of the stenotic area was performed taking the stenotic form into consideration and retaining the spinous process and interspinous ligament. In cases of stenosis of the spinal canal, posterolateral decompression of the dural sheath was performed by means of resection of the medial edge of the bilateral inferior articular processes and the yellow ligaments. In cases of stenosis of the spinal canal associated with stenosis of the lateral recess, the root was decompressed by unroofing the lateral recess in addition to posterolateral decompression of the dural sheath. And in cases with stenosis of the lateral recess, the root in an affected area was decompressed. Neither operation on the intervertebral disc nor incision of the dural sheath was performed. After operation as described above, symptoms, operative findings and postoperative results were investigated in 70 cases which could be directly examined. In this paper we discuss the relationship between the symptoms and the stenotic area, stenotic forms and stenotic factors. When our postoperative results were compared with those of cases with extensive laminectomy, it was seen that none of the patients we treated had low back pain nor recurrence of intermittent claudication and that lessening of paralysis was sufficient.

[4 Cases of malignant mesenteric tumor].

Four patients with malignant mesenteric tumors are presented. The first was an 81-year-old male who had non-Hodgkin's lymphoma, the 2nd a 66-year-old male with leiomyosarcoma, the 3rd a 35-year-old male with well differentiated fibrosarcoma. All 3 of these patients underwent radical excision. The 4th patient was a 63-year-old male who underwent exploratory laparotomy only. Postmortem study showed leiomyosarcoma. Based on those and published experiences, we suggest that as soon as a diagnosis of mesenteric tumor has been established with CT scan, GI series etc., surgical removal and Chemotherapy should be performed.

[Leiomyosarcoma of the rectum--a case report].

Tumors of smooth muscle origin are relatively uncommon in the rectum. Patients with leiomyosarcoma are very infrequently encountered. The patient was a 59-year-old Japanese male, who presented complaining of difficulty of defecation and melena. Rectal examination revealed an elastic hard and smooth-surfaced tumor of walnut size at 4 cm on the left antero-lateral wall. Needle biopsy was performed and the tumor was resected trans- sacrally. Histopathologically the tumor, was diagnosed to be leiomyosarcoma. Although the patient received no postoperative chemotherapy or irradiation, he is living without any symptoms or signs of recurrence 5 years and 6 months after the surgery.

Inhibition of virus-induced hemolysis with monoclonal antibodies to different antigenic areas on the hemagglutinin molecule of A/seal/Massachusetts/1/80 (H7N7) influenza virus.

A/seal/Massachusetts/1/80 (H7N7) influenza virus caused maximal hemolysis at pH 5.9 Monoclonal antibodies to each of the four nonoverlapping antigenic areas on the hemagglutinin molecule of the virus inhibited the hemolysis whereas those belonging to two of the groups did not inhibit hemagglutination of the virus. Hemolysis also occurred when the virus was incubated at pH 5.9 prior to addition of erythrocytes. Such hemolysis caused by acid-treated virus was inhibited with the antibodies as well. At pH 5.9, hemagglutination of neither intact virus nor hemagglutinin rosettes was inhibited with any of the monoclonal antibodies, indicating conformational change in the hemagglutinin molecule, at this pH. On the other hand, hemagglutination-inhibition was observed when the antigens were incubated with the monoclonal antibodies at pH 7.0 and then the pH was later shifted to 5.9, suggesting that antibody-binding interferes with the conformational change in the hemagglutinin molecule at pH 5.9. The present findings indicate that antibodies to the hemagglutinin of influenza virus can inhibit virus-induced hemolysis by blocking conformational change in the hemagglutinin molecule and blocking later step of fusion than the conformational change, in addition to blocking attachment of virus to the receptor of erythrocytes.

Human influenza virus infection in mink: serological evidence of infection in summer and autumn.

During the period from July to November 1981, 42 out of 128 young mink of a flock were found to possess antibodies against the viruses A/Bangkok/1/79 (H3N2) and A/Kumamoto/37/79 (H1N1), which were currently prevailing human influenza viruses. Seroconversion against A/Bangkok/1/79 was found in 12 mink from August to November. HI antibody titers of greater than 1: 128 were found in 8 out of 42 mink at the first examination in July and August. These findings suggest that infection with these human influenza viruses was present in this flock during the period from birth (the beginning of May) to autumn, the non-prevalent season in man. Attempts at virus isolation were unsuccessful.

[A case of metastasis of rectal cancer to the thyroid gland].

A 34-year-old male who showed a rectal mass upon irrigoradioscopy was admitted on October 6, 1979. Abdominoperineal amputation of the rectum was performed on October 11. Histopathological examination revealed that the tumor was adenocarcinoma of the well differentiated type, s, n0., stage II. The patient received chemotherapy and immunotherapy for 10 months postoperatively. In September 1981, enlargement of the thyroid gland associated with pain was noted and on January 12, 1982 total thyroidectomy was performed. Histologically, a diagnosis of well-differentiated adenocarcinoma, which was a metastasis from the rectal cancer, was made. On August 15, 1982, the patient died of generalized metastases.
