a four day old female infant was admitted because of poor feeding, vomiting and jaundice. laboratory examination showed hyperkalemia, mild hyponatremia and renal tubular acidosis type 4. serum aldosterone and plasma renin activity were elevated but serum cortisol, 17 -hydroxyprogesterone, acth, 24 hour urinary 17- ketoste roid, pregnanetriol, renal function and sonogram were normal and hence ps...

BACKGROUND The use of normal saline is associated with hyperchloremic metabolic acidosis. In this study, we sought to determine the incidence of acute postoperative hyperchloremia (serum chloride >110 mEq/L) and whether this electrolyte disturbance is associated with an increase in length of hospital stay, morbidity, or 30-day postoperative mortality. METHODS Data were retrospectively collect...

BACKGROUND Calcium chloride solution is an established injectable sterilant in dogs and other mammals. With cat populations a continuing problem, we sought to explore its first use in cats. Six cats per group were injected with 5%, 10% or 20% calcium chloride dihydrate in saline solution with lignocaine hydrochloride, a local anaesthetic. RESULTS At the 60th day post-injection, cat testes wer...

The effect of temperature on the inhibition of serum cholinesterase by dibucaine, fluoride and chloride has been studied. It is found that the dibucaine and chloride numbers together are capable of differentiating the inherited enzyme variants at 30° and 37°C. Fluoride numbers contribute little information at these temperatures; indeed fluoride inhibition is so sensitive to temperature change t...

Hyperchloremia is a common electrolyte disorder that is associated with a diverse group of clinical conditions. The kidney plays an important role in the regulation of chloride concentration through a variety of transporters that are present along the nephron. Nevertheless, hyperchloremia can occur when water losses exceed sodium and chloride losses, when the capacity to handle excessive chlori...

INTRODUCTION Metabolic alkalosis is a commonly encountered acid-base derangement in the intensive care unit. Treatment with the carbonic anhydrase inhibitor acetazolamide is indicated in selected cases. According to the quantitative approach described by Stewart, correction of serum pH due to carbonic anhydrase inhibition in the proximal tubule cannot be explained by excretion of bicarbonate. U...

We propose a conceptual model for progressive freeze concentration, which predicts solute loss through inclusion in the ice based on system's phase behaviour as illustrated state diagram. compare outcomes of sodium chloride, sucrose, and bovine serum albumin (BSA). For growth rates order 10−2 μm/s there was no chloride or but above this range, local super-cooling gives rise to freezing zone. In...

The production of mutations in cellular tumor suppressor genes such as p53 is involved in the development of many human cancers. These mutations result in the expression of mutant forms of the encoded p53 protein which can potentially serve as a biomarker for this carcinogenic process. Workers exposed to vinyl chloride who are at risk for the development of the sentinel neoplasm angiosarcoma of...
