Effects of bacterial contamination of reagent water on selected laboratory tests.

The effects of three widely spaced levels of bacterial contamination of reagent water on several chemistry, radioimmunoassay, and coagulation procedures were studied. These included determinations of lactate dehydrogenase, creatine kinase, aspartate transaminase, alkaline phosphatase, blood urea nitrogen, total protein, thyroid-stimulating hormone, digoxin, thrombin time, activated partial thromboplastin time, and prothrombin time. Statistical analyses included calculations of means and coefficients of variation, and analysis of variance, as well as correlation coefficients for test results versus logarithm of bacterial contamination. Statistically and clinically significant differences occurred together only for an elevated level of creatine kinase.

Epidemic typhus infection in cynomolgus monkeys (Macaca fascicularis).

A nonhuman primate model of clinical Rickettsia prowazekii infections was developed in cynomolgus monkeys (Macaca fascicularis). Monkeys infected intravenously with 10(7) plaque-forming units developed clinical signs of illness and pathological changes characteristic of epidemic typhus infection in humans. Increases in total leukocyte counts, serum alkaline phosphatase, blood urea nitrogen, and serum glutamic pyruvate transaminase values were observed. Microscopic examination revealed typical typhus nodules in the brains of two monkeys that died. These data indicated that the cynomolgus monkey is a suitable model for study of the pathogenesis of epidemic typhus infection and may prove valuable in the evaluation of candidate R. prowazekii vaccines.

Partial purification and properties of two phospholipases of Bacillus cereus.

Slein, Milton W. (U.S. Army Chemical Corps Biological Laboratories, Fort Detrick, Frederick, Md.) and Gerald F. Logan, Jr. Partial purification and properties of two phospholipases of Bacillus cereus. J. Bacteriol. 85:369-381. 1963.-Culture filtrates of Bacillus cereus contain a phosphatasemia factor (PF) that markedly increases blood alkaline phosphatase after intravenous injection into animals, and that releases alkaline phosphatase from epiphyseal bone slices in vitro. Fractionation of culture filtrates of B. cereus with N,N'-diethyl-aminoethyl cellulose results in the separation of two phospholipases, one that has PF activity and one that inhibits PF activity in vitro. Growth of shaken cultures favors accumulation of the inhibitor, whereas static cultures yield more PF. Lethality for mice and hemolysin activity do not appear to be associated with the phospholipase that inhibits PF. The relationship of the lethal and hemolysin factors to the phospholipase that produces phosphatasemia is not clear. The effects of heat, trypsin, lecithin, and antiserum on the phospholipases are reported. The intravenous injection of relatively large amounts of the purified PF resulted in the depletion of bone alkaline phosphatase.

Tendon disease and adjacent bone erosion in dialysis patients.

Six out of 169 patients on maintenance haemodialysis showed spontaneous tendon rupture. In all six, bone erosion had previously been observed at the site of tendon insertion. In a further 13 patients whose tendons had never ruptured, marked bone erosions at the sites of tendon insertions were also observed. Both groups of patients, with tendon rupture and with bone erosion only, showed significantly greater blood alkaline phosphatase and parathyroid hormone levels than all the others. Moreover, osseous radiological findings of hyperparathyroidism were more marked in all these 19 patients than in the others. Bone erosion at the site of tendon insertion may be a true and specific sign of tendon disease in patients with uraemia. Our series shows that it bears a close relationship to hyperparathyroidism, and suggests that tendon disease is a specific sign of severe secondary hyperparathyroidism in patients with uraemia.

[Alendronate in postmenopausal women with osteopenia and osteoporosis: effects on bone mineral density during treatment and after withdrawal].

OBJECTIVE: To determine the efficacy of alendronate (Fosamax) administration and withdrawal on the bone mineral density (BMD) in postmenopausal women with osteopenia and osteoporosis. METHODS: Alendronate (10 mg) and calcium carbonate (containing calcium 500 mg) were administered daily to 25 Chinese menopausal women with osteopenia and osteoporosis for 6 months and to 15 women for 12 months. After the withdrawal of alendronate, calcium carbonate was administered continuously. Follow-up was made three times for the 6-month group: before treatment, 6 months after treatment, and 13 +/- 4 months (6 - 24 months) after aldoronate withdrawal, and was made four times for the 12-month group: before treatment, 6 months and 12 months after treatment, and 23 +/- 7 months (14 - 36 months) after alendronate withdrawal to determine the BMD of lumbar spine 2 approximately 4, neck of femur, Wards triangle, and greater trochanter and blood alkaline phosphatase (ALP). RESULTS: Compared to the baseline value, the BMD in lumbar spine and hip increased significantly 6 months after treatment in 6-month group, with the BMD in lumbar spine 2 - 4 increased by 5.3% (P < 0.001). In the 6 month group, no significant decline was found in the BMD in lumbar spine and hip 13 +/- 4 months after alendronate withdrawal, the BMD in greater trochanter even increased further compared with that 6 months after treatment. In the 12-month group, the BMD significantly increased except in the Wards triangle after 6 months' treatment with an increase by 4.2% in lumbar spine 2 - 4 (P < 0.001). After 12 months' treatment the increment of BMD in lumbar spine 2 - 4 was 6.1% (P < 0.001) and the BMD of the hip remained unchanged. 23 +/- 7 months after the alendronte withdrawal the values of BMD in lumbar spine and hip were almost the same as that 12 months after treatment. CONCLUSION: Alendronate increases the BMD in spine and hip, especially in lumbar spine. The skeletal benefits are maintained for at least 13 - 23 months in spine and hip after withdrawal of alendrenate.

Hepatic and renal oxidative stress in acute toxicity of N-nitrosodiethylamine in rats.

Nitrosoamines such as N-nitrosodiethylamine (NDEA) produce oxidative stress due to generation of reactive oxygen species and may alter antioxidant defence system in the tissues. NDEA was administered ip as a single dose to rats in LD50 or in lower amounts and the animals were sacrificed after 0-48 hr of treatment. The results showed that lipid peroxidation in liver increased, however no significant increase in kidney LPO was observed after NDEA administration. Superoxide dismutase (SOD) and glutathione reductase (GSH-R) activity increased in liver, however, catalase (CAT) activity in liver was inhibited in NDEA treated rats. Kidney showed an increase in SOD activity after an initial decrease along with increase in GSH-R activity in NDEA treated rats. However, kidney CAT activity was not significantly altered in NDEA intoxicated rats. Serum transaminases, serum alkaline phosphatase blood urea nitrogen, serum creatinine and scrum proteins were elevated in NDEA treated rats. The results indicate NDEA-induced oxidative stress and alteration in antioxidant enzymes in liver and kidney to neutralise oxidative stress.

[Familial hyperactivity of angiotensin-converting enzyme (ACE)].

An extremely high level of serum angiotensin-converting enzyme (ACE) activity was found in eight individuals, women aged 31, 60, 42 and 67 years, and men aged 50, 47, 23 and 50 years. They had consulted a specialist due to a wide range of non-specific complaints or abnormalities (fatigue, dyspnoea, arthralgia, kidney stones with high urinary calcium, neurological symptoms and an elevated blood alkaline phosphatase activity level). As each of these complaints could be a symptom of sarcoidosis, the ACE activity was measured. However, sarcoidosis was not diagnosed in any of these patients. A subsequent analysis revealed that all eight individuals had family members with a similar elevation of ACE. Therefore, the increase in ACE activity was familial. Patients with this disorder have serum ACE levels of between 3 and 7 times the upper limit of normal, whereas in the case of sarcoidosis, serum ACE levels rarely exceed three times this limit. Familial ACE hyperactivity is not accompanied by clinical symptoms. It is caused by a point mutation in the ACE gene, which results in the cell-bound ACE being more readily loosened from the cell surface into the circulatory system.

[Bone remodeling and mineral homeostasis].

The discovery of receptor activator of nuclear factor-kappaB ligand (RANKL) elucidates the mechanism of osteoclast differentiation and function regulated by osteoblasts. Osteoprotegerin (OPG), a soluble decoy receptor of RANKL, inhibits both differentiation and function of osteoclasts. OPG-deficient (OPG-/-) mice exhibited severe osteoporosis caused by enhanced osteoclastic bone resorption. Deficiency of OPG in human has been shown to result in juvenile Paget's disease. Blood alkaline phosphatase activity of OPG-/- mice was about four times as high as that of wild-type mice. These results suggest that osteoclastic bone resorption coincidentally induces osteoblastic bone formation by an unknown factor (called coupling factor). Collagen sponge disks containing bone morphogenetic protein-2 (rhBMP-2) were implanted into the dorsal muscle pouches in OPG-/- mice and wild-type mice, and bone mineral density (BMD) of the collagen sponge disks was determined every week for 3 weeks. No significant difference in BMD of the disc was observed between OPG-/- mice and wild-type mice. These results suggest that bone formation is accurately coupled with bone resorption at local sites in OPG-/- mice.

[Effect of hydrochlorothiazide on calcium metabolism in postoperative hypoparathyroidism].

Vitamin D3 administered to patients with postoperative hypoparathyroidism increases calcium absorption from the gut and calcium blood levels but leads to hypercalciuria and may produce renal lithiasis. Thiazides decrease calcium excretion with the urine. Therefore, an effect of combined therapy with hydrochlorothiazide, vitamin D3 and calcium on hypoparathyroidism was investigated. Twenty one women were selected out of 135 patients with postoperative hypoparathyroidism. These women were constantly given vitamin D3 (30,000-225,000 IU daily) and calcium. Normocalcemia, hyperphosphatemia and hypercalciuria were noted before the treatment with hydrochlorothiazide. Therapy normalized hypercalciuria but did not change mean differences in calcemia, phosphatemia, magnesemia, blood alkaline phosphatase and phosphates and magnesium clearance factors. Hypercalcemia and necessity to withdraw hydrochlorothiazide together with change of either doses or preparation of vitamin D3 were noted in three patients, including one patient in whom both hypercalcemia and hypercalciuria with the symptoms of vitamin D3 poisoning were observed. The author suggests that combined therapy with hydrochlorothiazide, vitamin D3 and calcium prevents hypercalciuria but may require changes in vitamin D3 dosage and withdrawal of hydrochlorothiazide in some patients.

[Diagnosis and treatment of parathyroid adenomas].

The classical manifestations of primary hyperparathyroidism (hypercalcemia, hypophosphatemia, hypercalciuria, increased blood alkaline phosphatase level, and bone changes of the type of generalized osteoporosis) were found in approximately half of patients in a group of 23 who were examined. When Recklinghausen's disease is suspected, the patients must be subjected to a purposeful examination. The intraoperative diagnosis of parathyroid adenoma is difficult. In distinction from thyroid tissue, a lymph node, and adipose tissue a parathyroid adenoma almost always has a vascular pedicle, which makes verification of the diagnosis easier.

Clinical trial with somatonorm in idiopathic growth hormone deficiency in children.

This article reports the efficacy and safety of treatment with Somatonorm in 9 children with idiopathic growth hormone (GH) deficiency in China. The growth velocity increased from 2.6 +/- 0.2 cm/year before treatment to 10.7 +/- 0.5 cm/year at the end of 1-year treatment. The increment of human growth hormone (hGH) level and area under the response curve above the baseline level were larger after one injection of Somatonorm at the dose of 0.1 IU/kg sc than that of 0.17 IU/kg im. Increments of delayed bone age were not significant. There was no correlation between the increase of height growth velocities and the serum Somatomedin-C (SMC) levels during hGH therapy (r = -0.055). Blood sugar levels and blood alkaline phosphatase concentrations increased significantly after therapy. There were no significant side effects. Serum T4 levels of 3 patients dropped below normal after treatment. Serum anti-hGH antibody appeared at 3-12 month in 2 patients, but it did not attenuate the growth velocity.

Oral toxicity of Madhuca butyracea Macb. saponins to albino rats.

Saponins, isolated from M. butyracea, were assessed for their acute and subacute oral toxicity in albino rats. Acute doses of saponins caused mortalities and LD50 and LD90 values were 330 and 430 mg/kg body wt respectively. Severe diarrhoea, restlessness and histopathological changes were observed in liver and kidney. Diets containing saponins at 0,250,500 and 1000 ppm for 14 weeks did not affect food intake, growth or organ weights, but induced mild histological changes in liver and kidney and altered the serum levels of alkaline phosphatase, blood urea nitrogen, cholesterol and proteins, particularly in female rats.

[Clinical-dispensary finding of patients with primary biliary cirrhosis].

Ten patients with primary biliary cirrhosis (PBC) were clinically followed under the conditions of follow-up care. The diagnosis of the patients was made vie biochemical immunologic, histological and instrumental investigations. The average term for follow up was 4 years and 5 months. All patients were actively checked up by summoning every 6 months. The average incidence of hospitalization at the clinic was 1 year and 5 months. Pruritus preceded all other symptoms--1 year and 11 months on the average. Jaundice was established 1 year and 7 months after the manifestation of pruritus and the dirty greyish pigmentation of the skin--1 year and 11 months after pruritus. Hepatomegaly was established 1 year and 7 months after pruritus. Increased alkaline phosphatase, blood bilirubin and cholesterol were observed in all patients and increase of IgM in 80 per cent, and antimitochondrial antibodies--in 70 per cent. Xanthelasma and xanthoma were found only in patients with high levels of cholesterol and total fats. The treatment with dihydrocortison induced stomach complaints (erosive gastritis), intersifying bone chanes in 20 per cent of the patients. X-ray and instrumental methods have a relative value in making the diagnosis of PBC. It could be concluded from the complex treatment that corticosteroids give complications and the treatment with cholestiramine--to attenuation of pruritus. The average survival after making the diagnosis is 6 years.

[Clinical experience with cefoxitin in infections associated with hematopoietic disorders].

Ten inpatients at the Second Department of Internal Medicine, Mie University Hospital, developed infections in the course of treatment for hematopoietic disorders and were administered cefoxitin (CFX). Patients suffered from the following infections: pharyngitis, 2; bronchitis, 2; pneumonia, 2; sepsis, 2; bacteremia, 1; suspected cases of bacteremia, 2; and fever of unknown origin, 1. The number of infections totaled 12 as 1 patient with pharyngitis also developed sepsis and 1 patient with pneumonia developed bacteremia. Duration for the administration of CFX ranged between 5 and 18 days with a total dosage of between 30 and 108 g. Of the 10 patients treated with CFX, 9 were treated concomitantly with micronomicin (MCR), doxycycline (DOXY), or sulbenicillin (SBPC), some were treated concomitantly with only 1 of the drugs and some were treated concomitantly with 2 of the drugs. The following clinical results were obtained: Following treatment, 4 patients were considered "excellent", 5, "good", and 3, "poor". Clinical efficacy rate was 75%. Four strains of Gram-positive cocci (1 strain of S. aureus, 2 strains of S. epidermidis and 1 strain of Streptococcus sp.) and 3 strains of Gram-negative rods (2 strains of P. aeruginosa and 1 strain of E. cloacae) were found in the clinical specimens of the 10 patients. These results differed somewhat from reported data that Gram-negative rods such as E. coli, Klebsiella sp., Pseudomonas sp., Serratia sp., are dominant. No serious side effects requiring cessation of treatment were observed. Elevations in the levels of S-GOT, S-GPT, serum alkaline phosphatase, blood urea nitrogen, etc. were observed.(ABSTRACT TRUNCATED AT 250 WORDS)
