Oral glucose tolerance curves were constructed for 50 normal pregnant women, 25 pre-diabetics and 25 cases of diabetic pregnant women of different degrees of disturbance in carbohydrate metabolism. The mean rise in blood glucose level after the intake of 50 g glucose, was 53% in normal cases, and only 41% in the prediabetic cases, due to increased insulin secretion in the prediabetic group. This group of pregnants gave flat-topped curves in 60% of the cases studied, as compared to 10% of the normal pregnant cases in the same study. This was attributed to delayed insulin secretion in the prediabetic group. On the other hand, all diabetic cases gave peaked glucose tolerance curves during the first hour after glucose intake. The results of insulin-glucose tolerance test, effect of fasting for four hours and tolbutamide sensitivity test suggested that the prediabetic pregnants showed hyperinsulinemia which became evident during fasting. The pancreas of the prediabetic responds more readily, by the release of insulin, to the stimulus of oral hypoglycemic agents, such as sodium tolbutamide, than in the case of normal pregnants. Measurements of serum inorganic phosphorus, serum potassium and serum alkaline phosphatase of these 3 groups of pregnants, showed a definite disturbance in the liver function of the prediabetics which became more obvious in the diabetic group.

Over a 12-month period, an ambulatory pediatric population receiving long-term anticonvulsants was surveyed for the presence of biochemical and radiologic rickets. There were 74 treated children and 95 matched controls. Elevations of serum alkaline phosphatase activity occurred in 31 of the 74 (42%) treated children (23 of 47 children between 2 and 10 years and 8 of 21 children between 10 and 16 years). This frequency of abnormal values was significantly greater than that which occurred in our control population. Calcium and phosphorus abnormalities were minimal in both treated and control populations. Radiologic rickets occurred in 6 of the 74 (8%) of the treated children and in none of the control population. Neither the severity of the rickets nor the degree of hyperalkaline phosphatasemia were correlated with age of the patient, duration, and/or dose of anticonvulsant therapy.

A total of 35 cases of periarticular new bone formation (PNBF) was observed among 160 patients with coma following severe craniocerebral trauma. All cases were associated with blunt trauma and none with penetrating wounds. Only 6 of 500 cases of acute non-traumatic hemiplegia developed PNBR, and all 6 of them followed craniotomy, brain surgery and coma. New bone formation first appeared mainly between 50 and 120 days after craniocerebral injury with prolonged coma. Three-quarters of the patients with PNBF showed involvement of the shoulder joint, but this was not associated with previous subluxation. Metabolic studies were done in some patients; no disturbances were found in the metabolism of calcium, phosphorus or alkaline phosphatase. The pathologic process of PNBF seemed to stabilize some 6 to 8 months following trauma, and surgery after this period produced functional improvement in the 3 patients in whom it was tried. No satisfactory pathophysiological explanation has been found for the phenomenon of PNBR. Prolonged coma is common to all patients who suffered from PNBF and is probably an etiologic factor. The absence of PNBF in cases of cerebrovascular accident with subluxations of the gleno-humeral joint and intensive physiotherapy seems to contradict the suggestion of microtrauma as an etiological factor.

In six animals hunted and four immobilized animals of red deer (Cervus elaphus L.) of both sexes and of different age, kept at three game preserves in Bohemia, the psychological values were ascertained: the number of erythrocytes and leucocytes, the hemoglobin content, the hematocrit, MCV, MCH, MCHC, the white blood count, the total serum protein, the fractions: albumin, alpha-, beta- and gamma-globulin, the activity of SGOT, and SGPT, the alkaline phosphatase and the metabolism of calcium, phosphorus, and magnesium in the blood serum. The blood from the heart shortly after killing of the animal was examined, and in immobilized animals the blood was taken from the vena jugularis. In the red deer, a variable intensity of the polyvalent infection of parasites of the species Dictyocaulus viviparus, Bicalulus sagittatus, Fascioloides magna, Paramphistomum spec., Haemonchus contortus, Ostertagia ostertagi, O. circumcincta, Trichostrongylus axei, Nematodirus filicollis, Chabertia ovina, and Trichocephalus globulosa was found. In the immobilized deer no marked deviations were found in the examined values of blood that had been taken within 10 minutes after the calming of the animals.

Forty-seven male Macaca mulatta, 3 to 4 kg weight, were inoculated intravenously or subcutaneously with various doses of yolk sac-grown Rickettsia rickettsii. Thirty-four macaques became febrile and exhibited signs of infection ranging from transient illness with a few days of fever to severe illness with subsequent death. The rash appeared more frequently in the macaques inoculated subcutaneously. Febrile macaques that survived had leukocytosis, with concomitant neutrophilia. Febrile macaques that died had, in addition, marked terminal leukopenia and thrombocytopenia. Packed cell volume of all febrile macaques decreased. In almost all of the febrile macaques, there were increased serum urea nitrogen, glutamic-oxaloacetic transaminase, and lactate dehydrogenase and decreased total serum protein and amylase concentrations. A few febrile macaques had increased bilirubin values and decreased sodium, chloride, phosphorus, and alkaline phosphatase concentrations. Changes did not occur in serum glucose, potassium, calcium, and glutamic-pyruvic transaminase values. The experimental form of Rocky Mountain spotted fever in the macaque provides a subhuman primate model for studying the pathophysiology of this disease.

Male rats weighing 220-250 g were injected i.m. daily with 0.1 mg commercial human growth hormone for 3 days or 12 days. The serum concentration of total calcium phosphorus and alkaline phosphatase were significantly elevated for some days and returned to normal values at the end of the test period. The parathyroid glands, as studied by light and electron microscopical morphometry showed signs of reduced activity at the 4th day and also at the 13th day: a lowered nucleo-cytoplasmic ratio and a decrease of rough endoplasmic reticulum, of Golgi apparatus and of plasmalemmal tortuosity. The findings suggest a hypercalcemic effect of growth hormone involving peripheral organs of calcium metabolism, especially kidney and bone, and a secondary suppression of parathyroid glands by hypercalcemia.20

Forty-one epileptic children, aged 2 to 16 years, receiving combinations of phenobarbital, phenytoin, and primidone, and 39 control children were studied. The epileptics demonstrated slight but significant reductions in serum calcium, phosphorus, and 25-hydroxyvitamin D concentrations, and a significant increase in serum alkaline phosphatase values. No significant difference in serum immunoreactive parathyroid hormone levels was noted. Further analysis of the data revealed that patients whose drug therapy included primidone had the lowest serum levels of calcium and 25-hydroxyvitamin D. They had also received the largest number of drugs for the longest duration, and had serum phenobarbital levels that were significantly higher than those of other patients. The minimal degree of vitamin D deficiency in our epileptic children contrasts with the results of other investigations and warrants emphasis. The reasons for this difference are not apparent.

Recent evidence has linked altered plasma vitamin D metabolite levels to the reported occurrence of hypocalcemia and other metabolic abnormalities in patients receiving anticonvulsant drugs. We have measured plasma levels of 25-hydroxyvitamin D (25-(OH)D) and 1,25-dihydroxyvitamin D (1,25-(OH)2D) in institutionalized patients on diphenylhydantoin (Dilantin) and/or phenobarbital therapy. Values were compared with those obtained in institutionalized patients receiving no drugs and with normal ambulatory subjects. Although plasma 25-(OH)D levels were lower in the patients on drugs, a deficiency of 1,25-(OH)2D, the tissue active metabolite of vitamin D, was not present. These results indicate that in patients taking anticonvulsant drugs, the serum calcium, phosphorus, alkaline phosphatase and parathyroid hormone (PTH) abnormalities are not caused by a defective formation of 1,25-(OH)2D.

The values of a number of biochemical variables have been studied before and after a 50-gram load of glucose orally. Reductions which were statistically significant were found for sodium, potassium, urea, total protein, albumin, calcium, phosphorus, urate, bilirubin, alkaline phosphatase, but not for bicarbonate, creatinine, creatine kinase, lactate dehydrogenase, aspartate aminotransferase, cholesterol, triglyceride or chloride. The magnitude of the changes was generally not great, but could be clinically appreciable. The differences may need to be taken into account in comparing population studies.

Metabolic balance and calcium kinetic studies were performed in four patients with Paget's disease before treatment with salmon calcitonin and during the early and late stages of the treatment, which lasted 9 to 19 months, A significant decrease in bone turnover and 24-hour urine hydroxyproline and serum alkaline phosphatase values was observed in all patients. In contrast, the calcium, phosphorus and magnesium balances did not change significantly. In agreement with this, the partial body calcium, measured by in vivo neutron activation analysis, did not change. Intestinal calcium absorption increased initially, but returned to baseline levels 9 to 19 months after the study began. During the initial period there was a small, significant, but transient decrease in tubular reabsorption of phosphorus; this was accompanied by a significant decrease in serum phosphorus values--probably a direct effect of calcitonin rather than evidence of secondary hyperparathyroidism. Administration of salmon calcitonin to patients with Paget's disease decreases bone turnover without affecting calcium and phosphorus balances.
