Abstract
Surfer's myelopathy is non-traumatic spinal cord injury which develops in beginner surfers. The patient was a 17-year-old female who developed severe paraplegia with bilateral sensory dysfunction below the groin and bladder/rectal dysfunctions after her first surfing lesson. A spinal-cord MRI performed six hours after onset revealed an intramedullary hyperintensity area from T8 to the conus medullaris on the T2 weighted images. Expansion of this hyperintensity area was observed on Day 3 and showed a reduction on Day 8. After providing intravenous methylpredonisolone, intravenous glycerol and intravenous edaravone, motor function and bladder/rectal functions began to improve after approximately three weeks. In this study, the expansion of the lesion in the early stages of the disease course was observed by sequential spinal MRI. Furthermore, a time lag between improvement according to imaging and improvement in symptoms was also observed.

Abstract
A 66-year-old woman presented with vertigo and deafness. Diffusion-weighted magnetic resonance imaging of the head showed multiple cerebral infarctions involving several blood vessel regions. A diagnosis of cardiogenic embolism was made, and anticoagulation therapy was begun. The woman had no additional symptoms until suddenly developing left hemiparesis one year later. She was again found to have multiple cerebral infarctions. The hemiparesis gradually improved, but ataxic gait and apraxia appeared and progressed over two weeks. Holter ECG, carotid ultrasound, and transthoracic/transesophageal echocardiography revealed no evidence of cardiogenic embolism. However, serum lactate dehydrogenase (LDH) and soluble interleukin-2 receptor (sIL2R) levels were elevated (LDH, 782 IU/l; sIL2R, 1,396 IU/ml), which suggested malignant lymphoma. Contrast chest/abdominal CT scan and gallium-67 scintigraphy revealed no evident lesions; however, random skin biopsy and open brain biopsy showed that blood vessels were infiltrated by CD20-positive atypical lymphocytes. These findings were consistent with intravascular large B-cell lymphoma. This type of lymphoma is known as a rapidly progressive disease with poor prognosis, but this case followed an indolent course, with a one-year interruption in disease progression.

Abstract
BACKGROUND Small-cell lung cancer (SCLC) is a common malignancy that is usually fatal, since it metastasizes and recurs even after aggressive chemotherapy. While the cellular origin of this cancer is not well established, the cells of certain tumors exhibit neuroendocrine markers, including L-dopa decarboxylase. PURPOSE We designed in vitro and in vivo studies to investigate whether the neuroendocrine features in classic SCLC cell lines were sufficient to make them sensitive to 1-methyl-4-phenylpyridinium (MPP+), a known neurotoxin that destroys nigrostriatal dopaminergic neurons. METHODS Both classic SCLC cell lines (NCI-H345, NCI-H510, NCI-H187, and NCI-H146) and variant SCLC cell lines (NCI-H417, NCI-H82, NCI-H446, and NCI-H524) were exposed to MPP+ (0-512 microM) for 3 days. Inhibition of DNA synthesis was determined by [3H]thymidine incorporation assays. In a related experiment, MPP+ was removed from the classic cell line culture, and the incorporation of [3H]thymidine was determined. In the in vivo study, male athymic nude mice received subcutaneous injections of 0.5 mL tumor cells with matrigel for 10 days to enhance tumor growth, followed by MPP+ at doses of 100-400 micrograms/d given intraperitoneally for 2 days. RESULTS All four classic SCLC cell lines showed great sensitivity to MPP+, with detachment from laminin substrates and inhibition of DNA synthesis. MPP+ interfered with [3H]thymidine incorporation and, thus, with DNA synthesis in classic SCLC cell lines at low doses (median +/- SD, 12 +/- 4 microM), whereas much higher doses (median, > 512 microM) were required to inhibit [3H]thymidine incorporation in the variant lines. Treated cells excluded trypan blue dye, showing that inhibition of DNA synthesis was not due to cytotoxicity, and the cells incorporated [3H]thymidine when MPP+ was removed from the culture medium, demonstrating that the inhibition was reversible. MPP+ inhibited the growth of the classic NCI-H187 and variant NCI-H417 cell lines implanted in nude mice. CONCLUSIONS These results suggest that MPP+ differentially interferes with DNA synthesis in SCLC cell lines in vitro; the selective inhibitory effect on classic cell lines suggests that the neuroendocrine properties expressed by classic SCLC cells may be responsible for the differential effect. IMPLICATIONS MPP+ exerts a cytostatic effect on these cell lines, and the differential sensitivity observed in vitro is maintained in vivo, suggesting that MPP+ or other pyridinium compounds may be of therapeutic value in SCLC.

Abstract
The effect of nerve growth factor (NGF) on proliferation/differentiation of mast cells was investigated in vitro. Although NGF alone neither supported colony formation of bone marrow-derived cultured mast cells (BMCMC) nor induced development of mast cell colonies from nonadherent bone marrow cells (NBMC), addition of NGF to the suboptimal dose of interleukin 3 (IL-3) significantly increased the numbers of mast cell colonies produced by BMCMC or NBMC in methylcellulose. When stimulated by IL-3 alone, cells in mast cell colonies were not stained by berberine sulfate, a fluorescent dye. In contrast, mast cells developing in methylcellulose cultures obtaining both IL-3 and NGF were stained by berberine sulfate. The fluorescence was abolished by the treatment of heparinase but not of chondroitinase ABC, suggesting that mast cells stimulated by IL-3 and NGF produced and stored heparin proteoglycan. The histamine content of BMCMC maintained by IL-3 was also increased by addition of NGF. Since BMCMC showed mucosal mast cell-like phenotype, NGF appeared to induce the phenotypic change to connective tissue-type mast cells (CTMC). In the culture containing BMCMC, 3T3 fibroblasts, and IL-3, the phenotypic change of BMCMC to CTMC was observed as well. Since NGF was detected in this coculture and since addition of anti-NGF monoclonal antibody suppressed the phenotypic change, NGF produced by fibroblasts appeared to induce the phenotypic change. Neither BMCMC alone nor IL-3 alone increased the concentration of NGF. Therefore, there is a possibility that BMCMC stimulated by IL-3 may induce the production and/or release of NGF by fibroblasts.

Abstract
The effects of culture matrix (agar, collagen, and methylcellulose) on differentiation of mast cells were investigated. Because berberine sulfate-positive colonies in agar were composed of macrophages but not of mast cells, the naphthol AS-D chloroacetate esterase reaction was used to identify mast-cell colonies. When bone marrow cells of WBB6F1 mice were cultured with conditioned media containing interleukin 3 (IL-3), numbers of mast-cell colonies were greater in collagen cultures than in agar and methylcellulose cultures. Electron microscopic examination revealed that mast cells developing in collagen and agar cultures were more mature than those developing in methylcellulose cultures. However, when bone marrow-derived cultured mast cells or purified peritoneal mast cells were plated, the efficiency of colony formation and size of colonies were comparable among agar, collagen, and methylcellulose cultures. Therefore, all three matrices tested had similar effects on the proliferation of mast cells. Collagen appeared to be suitable for differentiation of bone-marrow precursors and their maturation. Agar appeared to be suitable only for maturation.

Abstract
A monoclonal antibody to manganese superoxide dismutase (Mn-SOD) was measured in patients with epithelial ovarian carcinomas. An enzyme-linked immunosorbent assay has been developed to detect serum Mn-SOD. With this assay, only 0.9% of the 207 healthy females tested had more than 130 ng per milliliter of serum Mn-SOD. In contrast, 37 of 62 patients (59.7%) with epithelial ovarian carcinomas showed high levels of Mn-SOD. The serum Mn-SOD increased according to the clinical stage and declined to reflect the effects of therapy. Compared with CA-125, Mn-SOD showed a less frequent false positive rate (10%) in benign gynecological diseases. The determination of Mn-SOD levels proved to be a clinically useful marker for monitoring the response to treatment and to early detection of the recurrence of epithelial ovarian carcinomas.

Abstract
Small cell lung cancer (SCLC) is a fatal malignancy due to its propensity to metastasize widely and to reoccur after chemotherapy in a drug-resistant form. While most SCLC cell lines are anchorage independent for growth, laminin induced the attachment of five of six SCLC cell lines tested (NCI-N417, NCI-H345, NCI-H146, NCI-H187, NCI-H510, and NCI-H209). NCI-N417 SCLC cells adopted a flattened morphology on laminin, and a classic SCLC cell line (NCI-H345) demonstrated a neuron-like appearance while the other SCLC cell lines except NCI-H187 cells, attached but did not spread. Adhesion to laminin was associated with increased resistance to several cytotoxic drugs. Matrigel, an extract of basement membrane proteins, greatly accelerated tumor growth when coinjected with SCLC cells in athymic mice. A synthetic peptide from the B1 chain of laminin, cyclic-YIGSR (Tyr-Ile-Gly-Ser-Arg), inhibited laminin-induced SCLC cell adhesion and migration in vitro and reduced the size of the tumors they formed when coinjected with matrigel and YIGSR. These results suggest that the interaction of SCLC cells with laminin and possibly with other basement membrane proteins can enhance their tumorigenicity and drug resistance.

Abstract
The difference between the endometrial cancer incidence in Japanese and Finnish women (lower and higher incidence, respectively), was evaluated on the basis of data from cases of endometrial cancer, cervical cancer and benign gynecological disease in both countries. The comparison took into account the various personal and clinical characteristics of these cases. In endometrial cancer, Japanese and Finnish women had similar characteristics except for the age at first delivery, the age at last delivery and obesity. However, obesity in postmenopausal women in the two countries was similar. Common factors in the two countries included few pregnancies and deliveries, nullipara and single women. In cervical cancer, no difference between the characteristics of Japanese and Finnish women was found except that Japanese women had a higher frequency of pregnancy. In benign diseases, characteristics were similar to those of endometrial cancer in Finnish women, but this was not the case in Japanese women. These facts may indicate the number of Finnish women with endometrial cancer risk factors is greater than the number of Japanese women with these risk factors. This was thought to account for the difference in the incidence of endometrial cancer.

Abstract
Mutant mice of mi/mi genotype are osteopetrotic and are deficient in mast cells. The osteopetrosis of mi/mi mice can be cured by bone marrow transplantation from congenic normal (+/+) mice, and therefore, the cause of the osteopetrosis is attributed to a defect of osteoclasts. Since both osteoclasts and mast cells are the progeny of multipotential hematopoietic stem cells, we examined whether mast cells were defective in mi/mi mice. In spite of the deficiency of mast cells in tissues of mi/mi mice, mast cells did develop when spleen cells of mi/mi mice were cultured with pokeweed mitogen-stimulated spleen cell conditioned medium (PWM-SCM). The proliferative response of cultured mast cells (CMC) derived from mi/mi mice to PWM-SCM was comparable with that of CMC from +/+ mice. In contrast, when CMC were co-cultured with the NIH/3T3 fibroblast cell line in culture medium lacking PWM-SCM, only +/+ CMC entered into the S phase of the cell cycle and were maintained; mi/mi CMC gradually disappeared. Moreover, fibroblasts derived from the skin of mi/mi mice normally supported the proliferation of +/+ CMC. Thus, the mast cell deficiency of mi/mi mice appears to be due to the inability of mi/mi mast cells to respond to the proliferative stimulus presented by fibroblasts.

Abstract
Tumor cells attach, degrade, and migrate through basement membranes as they metastasize. Laminin, a major glycoprotein of basement membranes, promotes the metastatic activity of tumor cells by stimulating the attachment and migration of the cells and their secretion of collagenase IV. We have identified a synthetic peptide of 19 amino acids (Cys-Ser-Arg-Ala-Arg-Lys-Gln-Ala-Ala-Ser-Ile-Lys-Val-Ala-Val-Ser-Ala-Asp -Arg) from the sequence of the A chain of laminin that increases experimental metastases of the lungs by murine melanoma cells. The peptide is active when injected either intravenously or intraperitoneally. The peptide increased collagenase IV activity, a key enzyme in the breakdown of basement membranes, to the same extent as laminin. This peptide represents an active site on laminin for promotion of the metastatic phenotype and generates a probe for studying the regulation of malignant activities.

Abstract
A 14-year-old girl presented at the hospital after discovering an abdominal tumor. CT scan and ultrasonography indicated a hepatic tumor and also revealed the absence of the portal vein. The patient was admitted to excise the hepatic tumor. It was found that the venous blood from the small intestines flowed into the left renal vein and then emptied directly into the inferior vena cava. A tumor extending from the right lobe through the middle portion of the liver was excised. The postoperative course was satisfactory and marked regeneration of the residual hepatic tissue was observed. Also the blood level of ammonia in the superior mesenteric vein was low, approximately 120 micrograms/dl, compared to the normal value of 350 micrograms/dl in the portal vein. This low blood level may indicate the presence of some homeostatic control mechanism.

Abstract
In Japan, oral 5-FU has been popularly used as an adjuvant chemotherapy to surgical operation mainly gastrointestinal carcinomas. This drug is generally administered consecutively at a low dose over a long term, because of its distribution at high levels in the upper gastrointestinal organs after oral administration. The authors have attempted to introduce the oral administration of 5-FU as an adjuvant chemotherapy in the treatment of uterine cervical carcinoma, and the results of a preliminary trial are reported in this paper; that is, the 5-FU level in target organs was measured after oral administration of 5-FU in 44 cases of uterine cervical carcinoma. Judging from the 5-FU level in organs removed about 2 hours after preoperative administration of 5-FU at 300 mg, the distribution of the drug to bilateral lymph nodes and the uterine cervix was good, and when calculated on the basis of the trace as 0, the average tissue level was 0.0432 microgram/g in the left lymph node, 0.0104 microgram/g in the right lymph node and 0.0190 microgram/g in the uterine cervix. From the above, it was concluded that, in the application of oral 5-FU as an adjuvant chemotherapy to treatment of uterine cervical carcinoma, a different manner application procedure should be established from that used to treat gastrointestinal carcinoma; that is, 5-FU should be administered intermittently at a moderate dose.

Abstract
This report is concerned with multiple primary cancers developing in invasive uterine cancer. Second primary tumors were recorded 27 women with a total of 30 non-uterine cancer (exception of radiation-induced cancer). 17 patients of radiation-induced neoplasm were observed (Rectal cancer 4, soft part sarcoma 4, cancer of urinary bladder 3, bone tumor 3, uterine cancer 2 and cancer of Vulva 1). One case is 4 lesions (corpus, sigma, thymoma and stomach), 2 cases are 3 lesions (uterine cervix, stomach and maxillary sinus: uterine cervix, thyroidal gland and radiation-induced soft part sarcoma). Only 5 of these 17 patients were known irradiated dose (50 Gy approximately 55 Gy), however others unknown. The mean latent periods of 17 cases of radiation induced neoplasms are 19.4 years. 16 patients of late second cancers of the cervix appearing from 11 to 36 years (average 19.5 years) after initial radiotherapy were recorded.

Abstract
Late local recurrence of cervical cancer more than 10 years after successful initial treatment is very rare. We now present 17 patients with late local recurrence. Only one patient had undergone primary surgery alone; the other 16 patients had received various types of radiotherapy. All 17 patients received radiotherapy as the second treatment. Local control was achieved in 9 patients, 4 of these survived for more than 5 years after the second treatment. Longterm follow-up for more than 10 years is important for the early detection of late local recurrence.
