Clinical effects of EHDP on relief of bone pain, changes in bone lesions on X-ray and 99mTc-MDP scintigram and performance status were investigated in 19 patients with bone metastasis from urogenital cancers (4 renal cell cancers, 1 renal pelvic cancer, 4 bladder cancers and 10 prostatic cancers). EHDP was effective in relieving bone pain in prostatic cancer patients with osteoblastic lesions. Bone lesions on X-ray and 99mTc-MDP scintigram were slightly improved in prostatic cancer patients with osteoblastic lesions. Administration of EHDP did not improve the performance status. Changes in laboratory data such as serum alkaline phosphatase, serum calcium and urinary total hydroxy-proline following EHDP administration indicated inhibition of osteolytic activity with no effect on bone formation in the early period of treatment (in 4 weeks) and development of both osteolytic activity and bone formation in the later period (from 8 to 12 weeks). No marked side effects were observed. EHDP seems to be effective in relieving bone pain in prostatic cancer patients with osteoblastic bone metastasis. Moreover, some diphosphonate groups including EHDP are expected to be useful to the patients with malignant hypercalcemia.

Bone scintigraphy using 99mTc-MDP was performed on 2 patients with Paget's disease of bone before and after the treatment with a synthetic eel calcitonin analogue [Asu1,7)-eel calcitonin, ECT] at a dose of 40 U per day. All pagetic lesions showed markedly the increased accumulation of the radionuclide. The uptake ratio, defined as the count rate of 99mTc-MDP over each bone lesion to that over the control bone, was calculated. The response to the calcitonin therapy was evaluated with the uptake ratio of the radionuclide. The uptake ratio decreased markedly within the first 3 months of the treatment, in association with a palliation of bone pain, while the serum alkaline phosphatase activities which had been within the normal range or slightly high before the treatment did not show any significant change or did not reflect a clinical feature (e.g. bone pain) with the treatment. Thus, the uptake ratio on the bone scintigram seemed to offer the most sensitive and most reliable information for the evaluation of calcitonin treatment of Paget's disease of bone.

Findings of bone scintigraphy with 99mTc-MDP were compared with bone radiography and biochemical data including total acid phosphatase (T. ACP), prostatic acid phosphatase (P. ACP), and alkaline phosphatase (ALP) in 35 patients with histologically proven prostatic cancer. Bone metastases were diagnosed in 20 of 35 cases (57%) by scintigraphy. The common sites of metastases were the pelvic bones, ribs, lumbar and thoracic vertebrae. In vertebrae, metastases were mainly distributed in the lower level. The most frequent radiographic change due to metastases was the osteoblastic type. On follow-up studies, there was a relatively good agreement in the results of bone scintigraphy and radiography. However, there was a good number of cases showing discrepancy between either scintigraphy or radiography and laboratory data. Bone scintigraphy seems to be the most contributory in monitoring bone metastases from prostatic cancer.

Serum calcium, albumin, phosphorus, and alkaline phosphatase, urinary creatinine and retention of 99mTc-methylene bisphosphonate (99mTc-MDP) were measured in 61 subjects with osteoporosis and the values compared with those obtained in normal subjects. 99mTc-MDP retention was inversely related with urinary creatinine output in normal subjects. In osteoporotic subjects urinary creatinine output was lower and 99mTc-MDP retention higher even when urinary creatinine output was taken into account. Other measurements were similar. In 21 subjects these measurements together with urinary hydroxyproline were performed before and after treatment with calcium and vitamin D. 99mTc-MDP and alkaline phosphatase fell; urinary hydroxyproline was unchanged. A single 24 h urine measurement after 99mTc-MDP injection is a valuable method of predicting whether calcium and vitamin D therapy will be useful in a particular case of osteoporosis.

The circadian rhythms of maltase, alkaline phosphatase and dipeptide hydrolase were assessed in duodenum, proximal, medial and distal parts of the rat small intestine. Functional activities were assessed every 4 hrs for 24 hrs. Patterns of all enzymatic activities were different in different parts. The mucosal protein content in each segment of intestine was constant throughout the 24-hour period.

The occurrence of bone marrow carcinosis was investigated in 380 patients at the time of first recurrence of breast cancer. Results were related to results from radiographic bone survey, 99mTc MDP bone scintigraphy, clinical examination and serum alkaline phosphatase and serum calcium levels. Eighty-seven patients (23%) had tumor cells in the bone marrow. X-rays showed metastases in 78% of the patients with and in 16% of the patients without bone marrow carcinosis. The diagnostic efficiency of x-rays with bone marrow biopsy as the key diagnostic factor was 83%, and it was superior to that of other investigation methods. Bone tissue biopsies were positive alone in 15 patients (17%) and marrow aspirations were positive alone in seven patients (8%). Imprint preparations were positive alone in 7% of the patients and bone tissue biopsy in 5% of the patients. Heavy tumor infiltration (greater than or equal to 50%) of the bone marrow was associated with the occurrence of numerous regions of radiographically involved bone lesions and with histopathologic evidence of bone destruction. Furthermore, pronounced bone formation and marrow fibrosis were more commonly seen in patients with osteosclerotic bone metastases than in patients with osteolytic bone metastases. This study provides evidence that the primary soil of metastatic bone disease in human breast cancer is the bone marrow and that radiographic evidence of bone metastases is a result of an invasion and destruction of the bone tissue matrix by tumor cells from the marrow cavity.

Alpha-amylase was present in considerable amount in the chyme in rats both at rest and during digestion, in the latter case its level being increased. Activity of intrinsic intestinal enzymes dominated in the homogenate of the mucosa. Transition from fasting to feeding and digestion increased the level of alkaline phosphatase and dipeptidase activities in the homogenate of the mucosa. The data obtained suggest the final stages of biopolymers' hydrolysis to be localized in various enterocyte structures. The surface mucus, owing to absorbed pancreatic enzymes, binding proteins and other types of physiologically active molecules, is assumed to play the role of a specific molecular filter and take part in the initial stages of digestion.

We encountered 11 patients with aluminum-associated bone disease (AABD), and treated them with deferoxamine (DFO). In 3 patients, a second bone biopsy was done during DFO treatment. Clinical features of AABD were compared with surgically proven secondary hyperparathyroidism (2 degrees HPT) with osteitis fibrosa on X-ray. Patients with AABD had disabling bone pain. This disease showed radiological signs ranging from normal, localized bone atrophy, to multiple fractures. It was characterized by increased soft tissue activity and localized abnormal uptake of 99mTc-MDP, detected by skeletal scintigrams. Patients with AABD had low levels of parathyroid hormone and alkaline phosphatase, but high aluminum (Al) levels compared to those with 2 degrees HPT. Serum Al increased after DFO administration, and the patients improved both clinically and histologically. 1-alpha-Hydroxyvitamin D3 (1-alpha-OH D3) was not effective for AABD. We concluded that the administration of antacids containing Al should be minimized in dialysis patients.

A case of ossifying fibroma of the cranial vault is described. Several reports emphasized the rare existence of this lesion limiting in the cranial vault. The patient was a 76-year-old woman who suffered mild headache in the parietal region after a trivial head trauma. Physical and neurological examination were normal. Plain skull X-P revealed irregularly bordered, 4 X 4 cm sized radiolucent area in the left temporal bone. The bone scintigraphy using 99mTc-MDP showed an abnormal uptake like a doughnut. Levels of serum P, Ca and alkaline phosphatase were within normal range. A tumor was softer than normal skull, and undertaken piecemeal removal. The dura was normal. After the total removal of the tumor, cranioplasty using Resin plate was performed. Microscopically the lesion was composed immature, irregular spicules of bone and fibrous tissue. Abundant fibroblasts were arranged in a random fashion in the stroma. Characteristically, the spicules of bone surrounded by rimming of osteoblasts. Ossifying fibroma is a benign fibroosseous tumor. Although this tumor is typically found in the maxillary sinus and mandible, it has also been reported in the paranasal sinuses, frontal, ethmoid, sphenoid bone and orbital roof of the young adult. But previously reported cases involving the cranial vault alone were only 7 cases. Etiology of ossifying fibroma is almost unknown.

Some intestinal enZymes were assayed which were related to: (i) Cellular proliferation, for example, aspartate carbamoyltransferase, thymidine kinase, uridine kinase, and dihydroorotase; (ii) cellular differentiation, for example, lactase, invertase, maltase, alkaline phosphatase, and dipeptidase; and (iii) lysosomes, for example, beta-glucuronidase, acid beta-galactosidase, and acid phosphatase. These enzymatic determinations can be used to distinguish the crypt from the villus during healthy or diseased states.
