Abstract
A 73-year-old man underwent distal gastrectomy, D2 lymphadenectomy, and Billroth Ⅰ reconstruction for Type 3 advanced cancer in the lower corpus lesser curvature in 20XX. After postoperative adjuvant chemotherapy, he self-detected a mass in the left breast. It was diagnosed as breast cancer. He underwent mastectomy and axillary lymphadenectomy 16 months after gastric cancer surgery. After postoperative adjuvant chemotherapy, gastric or breast cancer did not recur. However, periodic upper gastrointestinal endoscopy revealed an 8-mm 0-Ⅱa lesion in the anterior wall of the remnant middle stomach(Group 5)80 months after gastric cancer surgery. Endoscopic submucosal dissection(ESD)was performed, and radical resection was achieved. Periodic upper gastrointestinal endoscopy was performed thereafter; an ectopic 0-Ⅱa lesion was detected in the greater curvature of the remnant middle stomach(Group 5)21 months after ESD. Since this lesion suggested massive submucosal invasion, total resection of the remnant stomach and Roux-en-Y reconstruction were performed. The postoperative course has been favorable, and the patient has been alive without recurrence for 6 months postoperatively. A long period passes before intestinal juice reflux induces progression of a chronic inflammatory gastric mucosal lesion to cancer in the remnant stomach. Thus, long-term endoscopic follow-up may be necessary.

Abstract
A 36-year-old woman with benign phyllodes tumor of the left breast had undergone lumpectomy 1 year ago and was admitted to our hospital because of a left breast mass on the operation scar. Ultrasonography showed a 35 mm low-echoic, elliptical mass with a high depth to width( D/W) ratio in the C area and a 10 mm low-echoic, polygonal mass with a high D/W ratio in the E area. Histological examination of an ultrasonography-guided vacuum-assisted biopsy specimen indicated recurrent phyllodes tumor. Since both tumors were assumed to be recurrent phyllodes tumors, quadrantectomy was performed. Finally, the mass in the C area was diagnosed as a recurrent phyllodes tumor and the mass in the E area was diagnosed as a fibroadenoma. A non-invasive ductal carcinoma was incidentally detected between the 2 tumors, and the surgical margin was negative. Radiotherapy was performed on the remnant breast tissue.

Abstract
We treated 9 patients diagnosed with brain metastasis from breast cancer. Although 1 patient was initially diagnosed as having Stage IV disease, 5 had Stage I/II early breast cancer. All patients had defined brain metastasis after chemotherapy. Brain metastasis was symptomatic in 7 patients, 4 of whom had brain edema, and asymptomatic in 2 patients. The median survival time from breast cancer metastasis was 23 days for patients who did not receive radiotherapy and 19.6 months for those who received radiotherapy. Among the patients treated with radiotherapy, the median survival time was 4.3 months for patients who did not receive further treatment and 19.7 months for those who received chemotherapy or chemotherapy with trastuzumab. One patient with a solitary brain metastasis underwent stereotactic radiosurgery, and treatment is being continued for 1 of the 2 patients who received systemic therapy after whole-brain radiotherapy and additional stereotactic radiosurgery at recurrence to control brain disease. Systemic treatment after radiotherapy is important for brain metastasis from breast cancer, and early diagnosis of brain metastasis facilitates the use of various available treatments.

Abstract
A 59-year-old woman was admitted to our hospital because of right chest pain. CT scan showed a mass on the right abdominal wall and bilateral pleural effusion. The histological diagnosis following core needle biopsy was undifferentiated sarcoma. The right pleural effusion gradually increased despite negative cytology. Although we planned chemotherapy for the clinically diagnosed pleural invasion, thrombocytopenia as a paraneoplastic syndrome appeared. The minimum thrombocyte count was 4,000/mm3. While transfusion was not effective, per os dexamethasone at 2.0 mg/day kept the thrombocyte count at around 6×10 4/mm3. Anti-thrombocyte antibody was negative. Tumor resection surgery with partial diaphragm resection and 11th and 12th rib resection, and abdominal wall plasty with mesh was performed. The final histological diagnosis was dedifferentiated liposarcoma. The thrombocyte count returned to the normal range just after the operation. However, she died of pleural dissemination, peritoneal dissemination, and local recurrence 69 days after the operation.

Abstract
A 73-year-old man was referred to our hospital because of ileus. Enteroscopy revealed severe stenosis in the jejunum. He was diagnosed with small intestinal cancer. Partial resection of the jejunum, partial resection of the transverse colon, and lymphadenectomy were performed. A postoperative pathological examination showed skip metastasis in the jejunum (TNM: Stage IV). Six months later, lung and liver metastases were evident from computed tomography( CT). Nine courses of FOLFOX6 administered once every 2 weeks achieved a partial response. When 9 courses of chemotherapy had been completed, CT showed progressive disease. Subsequently, he has been administered with FOLFIRI in our outpatient clinic.

Abstract
CASE 1: A 64-year-old woman with right breast cancer had a partial mastectomy and radiotherapy four years ago was admitted to our hospital because of right breast mass. The vacuum associated biopsy of tumor resulted in breast sarcoma, thus a nipple-spearing mastectomy was performed. The final histological diagnosis was stromal sarcoma, and was identical to histological findings of malignant fibrous histiocytoma. Three months after the operation, a chest wall recurrence appeared. Although tumor resection with latissimus dorsi flap was performed, there were pleural dissemination and malignant pleural effusion. She died six months after the first surgery. CASE 2: A 60-year-old woman was admitted to our hospital because of left breast mass, but she refused a further clinical examination. She readmitted fourteen months later due to a huge sized left breast mass with necrosis and smelling discharge. CT scan showed a huge tumor of left breast and multiple lung metastases. Biopsy of the tumor resulted in breast sarcoma. Total mastectomy with split thickness skin grafting was performed. The final histological diagnosis was identical to the first case. A local recurrence appeared thirty days after the operation, and she died fifty-one days after the operation.

Abstract
We investigated 13 cases of axillary-lymph-node recurrence, who received an operation for an early stage breast cancer. They are the first recurrence of only regional without metastatic disease; the 4 patients, who had sentinel-lymph-node by biopsy at first operation, received an axillary lymph adenectomy, and 5 patients received re-lymph-adectomy after axillary lymph node dissection. The other 4 patients received only systemic therapy. Receptor conversion between primary and lymph-node recurrent site was identified for ER in 2 patients; one showed a lower expression of ER and the other showed for HER2. These led to a change in the subsequent treatment plan; 6 patients had systemic chemotherapy after recurrence, 1 patient had endocrine, 2 patients had trastuzumab and 4 patients continued the same treatment prior to surgery. Ten out of 13 patients were alive without recurrence, and 3 patients were with distant metastasis. However, one of the 3 patients who had a distant metastasis died due to brain and lung metastasis. Axillary node recurrence should be treated with axillary dissection, if possible, and receptor measurement in primary and recurrent site is useful for subsequent treatment.

Abstract
Esohophageal stents are often used in treating malignant stricture. But, when stents are placed across the esophagogastric junction, they may lead to esophagogastric reflux. We report a case of successfully treated esophagogastric strictures using the new stent with anti-reflux mechanism (long cover type Niti-S™ esophageal stent). A 78-year-old man presenting with severe strictures from the lower esophagus to cardiac part of stomach was histopathologically diagnosed as adenocarcinoma. CT scan images showed multiple liver metastatic tumors. However, he refused chemotherapy. Palliation using long cover type Niti-S™ esophageal stent was performed. No adverse effect was occurred. He started solid meals on the 7th postoperative day. He was thereafter able to ingest solid meals without the symptom of esophgogastric reflux and stenosis until he died of the primary disease two month later.

Abstract
Our objective was to evaluate the efficacy and toxicity of the pre-administration of UFT (uracil/tegafur: prodrug of 5-FU) and GEM combination therapy for unresectable/recurrent pancreatic cancer in the outpatient setting. UFT (250mg/m(2)/day) was orally administered from day 1 through day 6 and from day 8 through 13, and GEM (800mg/m(2), div/30 min) was administered on day 7 and 14, with a one-week rest every 3 weeks based on results of the previous phase I study. Thirty-six pts (24 male, 12 female) were enrolled (median age, 63.8 yrs). There were 8 partial responses (25%). Eighteen pts (56%) had stable disease, and 6 pts (19%) had a progression. The median survival time was 7. 0 months( range 1.5 -66). Grade 3 toxicities were leucopenia (17%), thrombocytopenia (3%), nausea (3%), and liver dysfunctions(3%). There were no Grade 4 toxicities. Pre-administered UFT plus GM is a promising treatment for unresectable/recurrent pancreatic cancer in the outpatient setting.

Abstract
We report two cases of bronchiolitis obliterans organizing pneumonia (BOOP) induced radiotherapy after surgery of breast cancer. One of the patients was a 58-year-old woman. She underwent a conserving surgery for bilateral breast cancers, and received radiation therapy to the remaining part of bilateral breasts. Two months after the termination of irradiation, cough, fever and general fatigue developed. We clinically diagnosed this case as BOOP after radiation therapy. After initiation of oral steroid therapy, the clinical symptoms and radiographic findings disappeared. Another patient was a 57-year-old woman. She underwent radical mastectomy for right breast cancer. A month after the operation, she suffered from local recurrence, so radiation therapy to the thoracic wall was performed. After irradiation, resection of the thoracic wall lesion was performed because of malignancy from local skin biopsy specimen. Two months after the termination of irradiation, cough, dyspnea and fever developed. We clinically diagnosed this case as radiation-induced BOOP by BAL and TBLB findings. After an initiation of steroid therapy, the clinical symptoms and radiographic findings disappeared. It is important to be aware of BOOP as a complication in the patient who was given radiation after surgery of breast cancer.

Abstract
We reported three cases of patient with triple negative skin metastasis after mastectomy of breast cancer. All three cases had received radiotherapy for skin metastasis. Radiation therapy was effective for recurrent sites, and could improve patient's QOL. After radiotherapy, 2 patients died due to a distant metastasis. Case 1 was resistant to chemotherapy. Case 2 was no indication of chemotherapy because of dementia metastases. Case 3 was the only one continued chemotherapy. It appears that a further consideration was needed for the timing of radiotherapy to be performed among the treatments of locoregional recurrence and distant metastasis of breast cancer.

Abstract
A 63-year-old female diagnosed as rectal cancer underwent low anterior resection and received adjuvant chemotherapy (folinate/tegafur/uracil therapy). After 6 months, lymph node metastasis was confirmed by an elevation of the tumor marker (CEA) and a FDG-PET image. After administration of 37 courses of mFOLFOX6 therapy, surgical excision was performed to the lymph node recurrence, because it was difficult to continue mFOLFOX6 therapy with grade 3 neuropathy. After 8 months from the last operation, no lymph node metastasis was appeared in the para-aortic area.

Abstract
We evaluated a surgical resection and chemo-endocrine therapy and prognosis for patients with local recurrence or axillary lymph node metastasis of breast cancer. Twenty-one patients with local recurrence or axillary lymph node metastasis without a distant metastasis were enrolled in this study. Thirteen of the 21 patients underwent a surgical resection. Resection of recurrent lesion in residual breast after breast conserving therapy for six of the 13 patients, axillary lymph node dissection (ALND) for four, and resection of thoracic wall lesion for three were performed. Five of the patients who underwent resection of residual breast lesion, four of the patients who underwent ALND and two of the patients who underwent resection of thoracic wall lesion have survived. One of the patients who underwent resection of residual breast lesion and one of the patients who underwent resection of thoracic wall lesion were dead. In eight non-operable patients, five were dead and three have survived. Median recurrence free interval was 24 months in operable patients and 27 months in non-operable patients. Median survival time after recurrence was 29 months in operable patients and 12 months in non-operable patients. The surgical with chemo-endocrine therapy promises to control well to local recurrence or axillary lymph node metastasis for the patients we selected.

Abstract
We report two patients having recurrent breast cancer with brain metastases that was controlled well with a gamma knife radio-surgery. The patient is a 50-year-old woman. She underwent radical mastectomy for right breast cancer in September 1993. She suffered from multiple liver metastases in June 2000, so CEF therapy contained hepatic arterial infusion chemotherapy, and extended right lobectomy of the liver were performed in December 2001. Afterward, pleurodesis was carried out to the carcinomatous pleurisy. Then she underwent simple total hysterectomy and bilateral oophorectomy for torsion of the metastatic ovarian tumor. MRI study revealed brain metastases with a diameter of 1 cm in her right midbrain in April 2005, so a gamma knife radio-surgery was performed. After the radio-surgery, a weekly paclitaxel therapy followed by peroral chemotherapy with capecitabine was started, and she took the regimen continuously. Another patient is a 56-year-old woman. She underwent skin sparing mastectomy with axillary lymph node dissection for right breast cancer in November 2002. Metastases to the base of her skull were found in October 2004, so a gamma knife radio-surgery was carried out. After the radio-surgery, a weekly paclitaxel therapy with anastrozole was started. In both of the two patients, the metastatic brain tumors have not shown growth so far and are under good control as of March 2006.

She underwent radical mastectomy for right breast cancer in September 1993. She suffered from multiple liver metastases in June 2000, so CEF therapy contained hepatic arterial infusion chemotherapy and extended right lobectomy of the liver were performed in December 2001. Right pleural effusion was detected in December 2003, then, pleurodesis was carried out with OK-432 after thoracic drainage. After pleurodesis, a weekly paclitaxel therapy was started and she was taking the regimen continuously. Another patient is a 55-year-old woman. She underwent radical mastectomy for left breast cancer in September 1999. Local recurrent lesions on the left chest and left pleural effusion were found in May 2003. After thoracic drainage, infectious pleurisy was complicated, so the drainage tube was removed after the therapy for preventing infection. After pleurodesis, CE therapy followed by peroral chemo-endocrine therapy was performed. Both of the two patients are receiving outpatient treatment without recurrent pleural effusion as of July 2005.

Abstract
The prognosis and QOL of unresectable pancreatic cancer are very poor. A symptomless 60-year-old male was admitted for examination of a high serum CA19-9 level. Following ultrasound and abdominal CT, we diagnosed unresectable advanced pancreatic cancer with multiple liver metastasis. After we obtained his informed consent, we administered continuous infusion of 5-FU and low-dose cisplatin (CDDP) infusion (low-dose FP therapy) for 3 weeks. He then underwent combination chemotherapy with low-dose CDDP and TS-1 on an outpatient basis. During the chemotherapy, he did not experience any major adverse event and his QOL was relatively good. On follow-up CT 3 months later, the primary tumor in the pancreas was found to be stable. However, the size and number of liver tumors were remarkably reduced. The serum CA19-9 level had also remarkably decreased from 48,300 U/ml to 1,480 U/ml. In conclusion, the combination chemotherapy using low-dose CDDP and TS-1 can be effective in cases of unresectable pancreatic cancer with multiple liver metastasis.

Abstract
A 46-year-old woman underwent right mastectomy for stage IIA breast cancer in 1993. Six years and 8 months after this operation, she was diagnosed as having multiple liver metastasis form the breast cancer. An intra-arterial catheter was inserted percutaneously into the hepatic artery and she was given hepatic arterial infusion chemotherapy and general chemoendocrine therapy. The metastatic liver tumors were gradually reduced in size and tumor markers returned to the normal range. However, tumor size was unchanged after February 2001. After obtaining her informed consent from the patient, we performed hepatic resection in December 2001. Histopathologically, three scars were observed and no tumor cell was found. She has been free from recurrence to date. This case suggests that chemoendocrine therapy including hepatic arterial infusion chemotherapy is effective for breast cancer patients with liver metastasis.

Abstract
We report an 82-year-old Japanese woman with basal cell carcinoma of the left nipple and areola extending into the lactiferous duct. The patient developed a small papular lesion of the left areola about 1 year before admission. The lesion, which had slowly progressed to involve the nipple, had become symptomatic showing weeping and bleeding. Mammography revealed microcalcification in the nipple. Although Paget's disease was suspected from these clinical features, histologically basal cell carcinoma was diagnosed. There was no axillary lymphadenopathy, and no evidence of distant metastasis. The lesion of the nipple and areola was resected with a 2 cm free margin along with the underlying mammary tissue. The patient has remained well without signs of recurrence for 2 years after surgery. We reviewed cases of basal cell carcinoma of the nipple or areola and discuss considerations and problems of this rare tumor.

Abstract
Two patients with advanced colorectal cancer were consecutively administered two different chemotherapeutic regimens. The first patient showed an initial response to combination treatment with irinotecan plus cisplatin, but then progressed. He subsequently responded to treatment with a novel thymidylate synthase (TS) inhibitor, raltitrexed. The second patient, who progressed after exhibiting a response to raltitrexed, subsequently responded to irinotecan/cisplatin combination therapy. In conclusion, no clinical cross resistance between the regimens of irinotecan/cisplatin combination therapy and raltitrexed was observed in these patients with advanced colorectal cancer.

Abstract
We examined the carcinogenicity of N-butyl-N-(4-hydroxybutyl)nitrosamine (BBN) in transgenic mice deficient in the metallothionein (MT) I and II genes and in control (129/Sv) mice. Both strains of mice were given BBN for 8 weeks with or without Zn treatment. All mice were killed at 12 weeks after the cessation of BBN administration. BBN induced bladder tumors in 75% of MT null mice and in 43% of 129/Sv mice. The average number of bladder tumors per mouse was significantly higher in MT null mice (1. 18 +/- 0.27) than in 129/Sv mice (0.43 +/- 0.20). Zn treatment suppressed the carcinogenicity of BBN in 129/Sv mice but not in MT null mice. Histopathological examination of the tumors revealed that the malignant potential of bladder tumors in 129/Sv mice was greater than that in MT null mice. These results indicate that MT is an important modulator of carcinogenicity of BBN in the bladder of mice.

Abstract
We developed a combination protocol for inhibitors of thymidylate synthase (TS) and DNA topoisomerase I (Topo I) that can exert highly lethal effects in vitro against HCT-8 human colorectal cancer cells. The specific schedule was constructed so that a TS inhibitor could induce not only primary DNA damage but also cellular conditions optimal for the efficient action of a Topo I inhibitor. The initial drug treatment consisted of a brief exposure to a quinazoline-based antifolate, ZD1694. After an interval of approximately one cell-doubling time, cells were exposed for 8-24 h to BNP1100, a Karenitecin-class 7-thiomethyl-camptothecin, in the presence of 1-10 microM thymidine; the latter acted as a crucial factor to promote the collision of moving replication forks with the drug-stabilised DNA-Topo I cleavable complexes even under continuous TS inhibition. Clonogenic analyses confirmed that these mechanistically distinct drugs at clinically achievable concentrations worked in a highly synergistic manner, with a maximum effect abolishing the viability of virtually all cancer cells (> 99.9%). The pretreatment with ZD1694 increased the amount of DNA-bound Topo I by up to 4-fold and the DNA-damaging capability of BNP1100 by up to 15-fold. The possibility of at least four DNA-damaging pathways is proposed which might have resulted from the individual actions of TS and Topo I inhibitors as well as their concerted actions. Taken together, the present findings provided a logically permissible explanation as to why TS and Topo I inhibitors in concerted interactions induced a highly lethal effect which was more than a simple additive effect. Since these drugs are effective specifically on actively proliferating cancer cells, but not on non-cycling G0/G1 cells, this mechanism-based protocol may warrant consideration for clinical verification.

Abstract
Endoscopic therapies for the treatment of cancers of the digestive tract have been improved. Today, some early cancers can be curatively treated by endoscopy (endoscopic polypectomy, endoscopic mucosal resection, heatprobe method, etc.). In addition, endoscopic local injection chemotherapy is performed for some advanced cancers as an adjuvant therapy. Recent progress in endoscopic therapies for cancer is reviewed in this paper, including their historical background. Improvements in these endoscopic treatment methods are expected to provide increased advantages for the treatment of patients with cancer in the near future.

Abstract
We examined whether gargling with black tea prevents influenza infection. Tests were carried out during a five month period (October 1992 to March 1993). The control group that followed their normal daily routine, whereas the test group that gargled with 0.5 w/v% black tea extract twice daily (at 8 a.m. and 5 p.m.). Influenza viruses were isolated from influenza patients and an antigen analysis was carried out. As a result, two strains of influenza A viruses (H3N2) and ten strains of B virus were detected. An HI test was done using paired sera of the control group and the test group. The HI titers raised a four fold or greater in 48.8% (61/125) in the control group and 35.1% (35/134) in the test group. There was a significant difference (p < 0.05) between the control and test groups. These results indicate that black tea extract is effective as a prophylactic agent against influenza infection.

Abstract
The effects of nefiracetam (DM-9384, CAS 77191-36-7) on the learning behavior and cholinergic and GABAergic neuronal transmitter systems of rats with experimentally-induced cerebral embolism were investigated. Cerebral embolisms were induced in male Wistar rats by injection of 800 microspheres 50 microns in diameter via the left internal carotid artery under 2% halothane anesthesia. Daily oral administration of nefiracetam (30 mg/kg/d) was started 9 days after embolization. Nefiracetam caused significant (p < 0.05) improvement of deficits in the learning of both water maze and passive avoidance tasks beginning 22 days after embolization of the rats. The drug also significantly restored decreases in cortical choline acetyltransferase (p < 0.05) and hippocampal glutamic acid decarboxylase activities (p < 0.01) in the embolized cerebral hemisphere and significantly increased cortical choline acetyltransferase (p < 0.05) and acetylcholinesterase activities (p < 0.05) in the contralateral cerebral hemisphere 21 days after embolization. These results demonstrate that nefiracetam improves cognitive dysfunction in the late phase in embolized rats and suggest that the effect is at least partly due to the increase in glutamic acid decarboxylase, choline acetyltranseferase and acetylcholinesterase activities.

[The clinical significance of PIVKA-II determination in patients with hepatocellular carcinoma: a comparative study with alpha-fetoprotein]. NIHON GEKA GAKKAI ZASSHI 1990; 91:588-93.

Abstract
The changes in the plasma level of PIVKA-II (Protein Induced by Vitamin K Absence or Antagonist-II) following the treatment or progress of the disease was studied in 60 patients with hepatocellular carcinoma. The positivity rate determined by the changes in PIVKA-II was 58.4 percent (35/60 cases) and was about the same as those reported so far, all of which were obtained by a single determination of PIVKA-II. Plasma PIVKA-II was elevated in 61.9 percent (13/21 cases) of alpha-fetoprotein negative patients and it was almost identical with the overall positivity rate. In parallel with serum alpha-fetoprotein, the plasma level of PIVKA-II was decreased after the surgery or transcatheter arterial embolization and was increased when the recurrence or progress of the disease was observed. Furthermore, the nonspecific elevation of PIVKA-II due to the associated liver cirrhosis or chronic hepatitis was infrequent compared with that of alpha-fetoprotein. In 18 cases positive with both PIVKA-II and alpha-fetoprotein, a close correlation (R = 0.91) was observed between the changes of these markers during the progress or treatment of the disease. Thus, it was suggested that determination of PIVKA-II in blood might be useful not only in the diagnosis but in monitoring the progress or the effectiveness of treatments in hepatocellular carcinoma.

Abstract
Various derivatives of L-cysteine obtained by conversion to an -S-S- bond in the mucoprotein by means of -SH in the chemical structure are widely used as expectorants because they show mucous dissolving action. Recently, there have been reports that L-cysteine derivatives lower the potencies of various antibiotics. Various types of antibiotics and cysteine-type expectorants are often used concomitantly for the treatment of bacterial infections in respiratory tract diseases, and any decrease in the antibiotic potency presents a major therapeutic problem. We investigated the effects of four cysteine derivatives on 12 antibiotics, ampicillin (ABPC), amoxicillin (AMPC), sulbenicillin (SBPC), cefazolin (CEZ), cephalexin (CEX), cephalothin (CET), oxytetracycline (OTC), doxycycline (DOTC), minocycline (MINO), erythromycin (EM), ribostamycin (VSM) and lincomycin (LCM), widely used clinically in vitro with the minimum inhibitory concentration (MIc) obtained by the liquid dilution method as an index. L-Cysteine, acetylcysteine, ethylcysteine and mecysteine lowered the potencies of almost all of the antibiotics at high concentrations (500 mcg/ml), but at low concentrations (12.5 mcg/ml), mecysteine lowered the potencies of only three antibiotics and L-cysteine those of only four antibiotics, while acetylcysteine decreased the potencies of six and ethylcysteine those of seven antibiotics.

Abstract
In a previous paper, we demonstrated that an inhibitory action of excess iodide on thyrotropin-induced thyroid hormone secretion occurs at a site subsequent to the generation of cyclic AMP. In the present study, however, we have found that thyroidal cyclic AMP formation induced by thyrotropin in vitro was markedly inhibited by the acute administration of excess iodide to mice fed a low iodine diet. In contrast, excess iodide failed to produce inhibition in animals fed a regular diet. In vitro stimulation by long-acting thyroid stimulator (LATS), prostaglandin E2, and 4-methylhistamine of cyclic AMP formation in mouse thyroid lobes was also significantly inhibited by the acute in vivo administration of excess iodide. The inhibition was completely relieved by the administration of methimazole prior to excess iodide. Furthermore, it has been shown that thyroid adenylate cyclase activity induced by thyrotropin was markedly depressed by excess iodide under similar experimental conditions. Therefore, it is suggested that one of the inhibitory actions of excess iodide is on the adenylate cyclase-cyclic AMP system and further, that iodide can elicit its inhibitory action after its conversion to some form of organic iodine.

Abstract
Concanavalin A (Con A) was tested for its ability to affect thyroid activation induced by the thyroid stimulators in mouse thyroid tissues. Con A was found to have the biphasic stimulatory and inhibitory effects of thyrotropin (TSH)-induced cyclic AMP formation and endocytosis, a step in thyroid hormone secretion, in mouse thyroid tissues. Low concentrations of Con A potentiated TSH-stimulated cyclic AMP formation and endocytosis. In contrast, high concentrations of Con A markedly inhibited TSH stimulations. These effects were reversed by the addition of methyl-alpha-D-glucoside to the second preincubation medium (without Con A) prior to TSH. A high concentration of Con A alone did not depress the basal levels of cyclic AMP or basal glucose oxidation in thyroid tissues. A high concentration of Con A also inhibited cyclic AMP formation induced by prostaglandin E2 and the long-acting thyroid stimulator (LATS). Binding of 125I-labeled Con A to thyroid tissues increased with time up to 75 min and was very slowly reversible after attainment of equilibrium. Binding was directly proportional to tissue weight. Scatchard plot analysis on the binding of 125I-labeled Con A to thyroid tissues indicated a positive cooperativity which seemed to be well correlated to the biphasic effects.
