Gallstones, serum lipids, and glucose tolerance among male officials of Self-Defense Forces in Japan.

The relationships of gallstones and the postcholecystectomy state with serum total cholesterol, serum triglycerides, glucose tolerance, and obesity were examined in male officials of the Self-Defense Forces in northern Kyushu, Japan. The study population had rather low rates of gallstones (2%) and prior cholecystectomy (3%). A strong relationship between obesity and gallstones was confirmed. Glucose intolerance was associated with the risk of gallstones independent of obesity. No relation between gallstones and either serum total cholesterol or triglycerides after adjustment for obesity and glucose tolerance was evident. However, the serum concentration of total cholesterol among men having had a cholecystectomy was less than that of those without gallstones.

The effect of ceruletide on tardive dyskinesia: a double-blind placebo-controlled study.

1. In a double-blind placebo-controlled study of 37 patients with tardive dyskinesia, the therapeutic effect of ceruletide was evaluated. 2. The patients were assigned at random to two groups that received either intramuscular injections of 0.8 micrograms/kg of ceruletide or placebo once weekly for 4 weeks. Conventional neuroleptic medication was not changed 3 weeks prior to and throughout the study period. Tardive dyskinesia was assessed using the Abnormal Involuntary Movement Scale over an 8-week period. 3. Ceruletide had a more pronounced effect on TD than the placebo however, because of the limited number of subjects examined, the difference between the two groups was not significant. Ceruletide was more effective than placebo in patients under 60 years of age (p less than 0.05) and whose antipsychotic medication was mainly butyrophenones. 4. No serious side effect was noted. 5. The findings suggested that ceruletide therapeutically benefits patients with tardive dyskinesia.

Malignant fibrous histiocytoma of the liver: a case report and review of the literature.

A case of primary sarcomatous tumor of the liver in a 61-yr-old man is reported. The tumor, which measured 8.5 X 8 X 8 cm, was located in the right lobe of the liver and consisted of spindle cells in a storiform pattern intermingled with bizarre giant cells. Immunohistochemically, most tumor cells expressed vimentin. Cytoplasmic immunoreactivity with alpha 1-antitrypsin and lysozyme was documented in the giant cells. Ultrastructurally, cells with fibroblastic and histiocytic features were present. The morphological and immunohistochemical findings justify the conclusion that the tumor should be classified as a malignant fibrous histiocytoma. Reported cases of hepatic malignant fibrous histiocytoma were reviewed and compared with similar tumors observed in other body sites.

Some secular changes in body height and proportion of Japanese medical students.

Anthropometric dimensions of 738 medical students at Kyushu University in Japan were analyzed to determine secular changes of height and body proportions during a 20-year period. Since 1961, means of standing height, leg length, and ratio of leg length to standing height have increased, although the rate of increase from 1971 to 1981 has been rather slow. On the contrary, the mean sitting height X 100/standing height has declined during this same period. Compared with data on the Japanese general population, the medical students were considerably taller, but the difference has decreased.

Indications for bilateral neck dissection in well-differentiated carcinoma of the thyroid.

This paper analyses the results of sixty-eight patients with thyroid carcinoma in whom bilateral modified radical neck dissection was performed, and discusses the indications for bilateral modified radical neck dissection. High frequencies of bilateral jugular lymph node metastases were found in eleven patients with obviously widespread involvement of both thyroid lobes, 13 with cancer mainly located in the isthmus, 2 with clinically detectable bilateral or contralateral jugular chain lymph node metastases, and 10 with recurrent thyroid cancer. Bilateral modified radical neck dissection, therefore appears to be indicated for those conditions. On the other hand, lymph node metastases in the contralateral neck were histologically confirmed in 6 out of 27 patients (22 per cent), in whom papillary carcinoma was clinically confined to one lobe, and where there were no obviously enlarged lymph nodes in the contralateral neck. In those patients, the histological confirmation of the contralateral thyroid lobe involvements, and of the contralateral paratracheal lymph node metastasis, appears to be a valid indication for elective contralateral modified radical neck dissection.

Ingestion of parsley inhibits the mutagenicity of male human urine following consumption of fried salmon.

The urinary mutagenicity of 3 nonsmoking, healthy men was investigated after strictly defined meals by means of the Ames Salmonella/microsome test. When the subjects ate 150 g of fried salmon at one meal, a potent mutagenicity of almost 5000 revertants of TA98 strain was present in all 6-h urine samples. On the other hand, less than 2500 revertants was present in the urine when the subjects simultaneously consumed 70 g of parsley and 150 g of fried salmon. Thus, the protection against mutagenicity affected by parsley warrants further attention.

Mutagenicity of human urine after the consumption of fried salted salmon.

Mutagenicity in the urine of four non-smoking individuals who had eaten salted salmon cooked at home for both lunch and supper was monitored by means of Salmonella/microsome mutagenicity tests. Extracts from fresh and salted salmon had the same level of mutagenicity after being cooked for 10 min at 200 degrees C, but no activity was detected before cooking. Salmonella strains TA98 and TA1538 were equally sensitive to the mutagens and required metabolic activation. No mutagenicity was shown with TA100 and TA1535. Urine samples were tested using a concentrate prepared by means of an XAD-2 resin column. Mutagenicity was detected mainly in urine excreted during 4-5 hr after the ingestion of cooked salmon, but only weak mutagenicity, or none at all, was detected in the urine after the ingestion of vegetables. The levels of urinary mutagenicity due to salmon consumption were not affected when cabbage was eaten simultaneously. The excretion of mutagenic substances was completed within about 20 hr, and there were almost no mutagens in the urine 24 hr after the ingestion of cooked salmon.

Follow-up study of type C influenza outbreak in a children's home.

A follow-up study of type C influenza in a children's home was made where the first outbreak of type C influenza occurred in March, 1981. During the survey period of 2 years, 2 additional outbreaks occurred in April and October, 1982 and 4 cases of the secondary and 2 cases of the tertiary infections were serologically confirmed. All of the children exposed to the outbreaks, except 2 particular cases who were suffering from German measles, showed similar mild respiratory symptoms characterized by fever and long-lasting nasal discharge, irrespective of primary, secondary, and tertiary infections. No case of inapparent infection was observed. Incubation period was estimated to be not longer than 5 days and the period of virus shedding, to be longer than 22 days. Antibody response in the sera of patients to type C influenza virus was equally good after every infection, although it was not efficient to prevent the succeeding infection. Factors involved in the repeated infections of type C influenza were discussed.

[PMU therapy of recurrent gastric cancer. A case report].

A 56-year-old woman with recurrent gastric cancer treated with PMU therapy, combined CDDP 75 mg/m2 i.v. MMC 10 mg/body i.v. and UFT 400mg/body/2 alpha/day p.o., was reported. She was admitted because of cervical lymph node swelling and abdominal tumor (para-aorta lymph node swelling). She was treated two times with this therapy and induced into complete remission. The serum CEA level, more than 500 ng/ml before the treatment, was reduced to 6.7 ng/ml after treatment. She has currently been free of disease for more than four weeks. We conclude that this PMU therapy is extremely effective for indurable gastric cancer.

[A case of advanced esophageal cancer resected curatively by preoperative chemotherapy with cisplatin].

A case of highly advanced esophageal cancer with bilateral multiple cervical lymph-node metastasis is reported. The largest size of lymph node was 5.0 cm in diameter, and intramural metastasis to the cardia of the stomach and provable invasion to the aorta were also seen. After treatment, with 100 mg/m2 cisplatin on two occasions these lesions were resected curatively. This preoperative chemotherapy would be expected to increase the resectability rate and possibly the survival rate.

Prevention of rotavirus infection by oral administration of cow colostrum containing antihumanrotavirus antibody.

After immunizing 8-month pregnant Holstein cows with human rotavirus, Wa strain, cow colostrum containing neutralizing antibody to human rotavirus, designated as Rota colostrum, was obtained. After randomly grouping 13 infants from a single orphanage, 6 infants received 20 ml of Rota colostrum every morning and 7 control infants received 20 ml of market milk. One month later, rotavirus associated diarrhea was observed in 6 of the 7 infants given milk and 1 out of the 6 infants given Rota colostrum. Orally administered Rota colostrum significantly protected infants from diarrhea caused by rotavirus (P less than 0.05). Two out of 5 Rota colostrum recipients who were free from diarrhea showed rises in complement fixation (CF) antibody titer after the rotavirus infection epidemic. Thus, Rota colostrum prevented the outbreak of diarrhea but did not prevent immunological responses to natural rotavirus infection. In the therapeutic trial Rota colostrum had no effect on duration of diarrhea, bowel movements or virus shedding in stool. However, there were no side-effects of Rota colostrum.

[Gonadotropin and alkaline phosphatase-producing gastric carcinoma with widespread metastasis to the bones].

A case of advanced gastric carcinoma in a 47-year-old man with widespread metastasis of generalized bone and associated with high serum levels of human chorionic gonadotropin (hCG) and alkaline phosphatase (ALP) is reported. Macroscopically, the primary tumor was Borrmann type IV. Microscopically, it showed poorly differentiated adenocarcinoma. Bone metastasis, however, showed well-differentiated adenocarcinoma. These lesions did not manifest conspicuous trophoblastic differentiation. Immunohistochemical studies revealed that hCG-positive cells were observed sporadically in the primary tumor and lymph node metastasis, but remarkably in the bone metastasis. Cancer cells in the lymph nodes were positively stained by modified Burstone's ALP staining. The serum levels of hCG and ALP fluctuated with the clinical course. Therefore, the authors concluded that this gastric carcinoma produced hCG and ALP.

[Radiotherapy (interstitial irradiation) of carcinoma of the tongue--an analysis of cases in the past 10 years].

A total of 82 histologically proven squamous cell carcinomas of the tongue, which were treated by interstitial irradiation (radium) at Chiba Cancer Center from 1973-1982, were reviewed. The cumulative five-year survival rate of all cases was 64%: 78% in Stage I and II group, 68% in Stage III and 47% in Stage IV. Local recurrence was noted in eight cases (10%) and later cervical node metastases in 14 cases 25% in T 1-4 N 0). The incidence of mandibular osteoradionecrosis was 18 cases (22%).
