An experiment was conducted in Algerian desert goats to study the effect of age and season on blood biochemical and mineral profile during different physiological stages of the goats. Serum Ca, Mg and Na levels were significantly high at birth and decreases as the age advanced. The season had a significant effect on the decreased levels of Ca, Mg and K and inversely on the increased levels of N...

Lithium concentrations in the serum of patients undergoing therapy with lithium salts were measured by atomic absorption spectroscopy. Serum was diluted 10-fold with water. Physiological amounts of sodium and potassium were included in the blank and standard solutions because these cations enhance the lithium signal by 2%. Calcium, magnesium, bicarbonate, sulfate, and phosphate at the concentra...

Direct read-out of chloride concentration is provided by an auxiliary designed for use with the automatic coulometric-amperometric titrator of Cotiove et al. (1). The circuitry, construction, and operation of the auxiliary are described. Automatic titration of samples of biologic fluids such as serum, cerebrospinal fluid, urine, sweat, and gastrointestinal fluids requires no prior preparation a...

This study was conducted to evaluate the quality of 11 honeys from arid regions for first time, and compare it with 5 different honeys from non-arid regions. Mean values obtained for physicochemical parameters were: pH 4.76 ± 0.55; 17.32 ± 1.8% moisture; 80.95 ± 1.60 °Brix sugar; 69.05 ± 4.41% total sugar; 413.81 ± 178.48 μS cm(-1) electrical conductivity; 17.58 ± 7.68 meq/kg free acidity; 11.0...

Complement receptor one (CR1) is essential for removing circulating immune complexes (CIC), with malaria infection contributing to the formation of large amounts of CIC. We investigated CIC levels in children with malaria, of varying severity and seasonality. Two hundred age and sex-matched severe and mild malaria cases were studied during and after active disease. Pediatric controls had increa...

Central pontine myelinolysis (CPM) is a dreaded complication from overly rapid correction of hyponatremia. Historically, the prognosis of CPM is dismal. Recent studies showed that improved neurological outcome was possible but reports on improvement in brain imaging are rare. We presented a patient who had not only complete neurologic recovery but also had significant regression on brain magnet...

Metabolic and electrolyte abnormalities, including hypokalemia, hyperglycemia and lactic acidosis, are associated with theophylline overdose. However, we report an unusual case of sinus tachycardia, lactic acidosis, hypokalemia and hyperglycemia associated with the usual theophylline dose in a patient with asthma. The theophylline dose was 200 mg orally twice daily. Three hours after administra...

tonitis. The laboratory findings were haemoglobin 9.6 g/dL, haematocrit 29%, serum urea 228 mg/dL, creatinine 7.6 mg/dL, sodium 135 mEq/L, chloride 110 mEg/L, potassium 7.1 mEq/L, albumin 2.4 g/dL, arterial pH 7.29, pCO2 15.7 mmHg, HCO3 7.5 mEq/L and BE −16.0. The abdominal X-ray showed an elliptical radiopaque mass∼7 cm in its highest diameter in the bladder region (Figure 1). Daily dialysis w...

CONTEXT Magnesium support to small bowel resection patients. OBJECTIVE Incidence and treatment of hypomagnesemia in patients with extensive small bowel resection. DESIGN Retrospective study. SETTING Metabolic Unit of the University Hospital Medical School of Ribeirão Preto, University of São Paulo, Brazil. PATIENTS Fifteen patients with extensive small bowel resection who developed shor...

An atomic absorption spectrophotometric (AAS) and a fluorometric method for the measurement of serum calcium were found to be corn-parablein acceptable reproducibility. The recovery figures obtained by the fluorornetric procedure were considerably lower than those given by AAS in the 2-4 mEq./L. range, although recoveriesat higher levels (6 mEq./L.) were acceptable. The average recovery for the...
