This paper presents an experimental investigation on the effect of partial replacement of cement by metakalion by various percentages viz 0%, 10%, 20%, and 30% on the properties of high performance concrete, when it is subjected to magnesium sulphate attack. An aggregate binder ratio of 2 and different water binder ratios viz 0.3, 0.35, 0.40 and 0.45 was used in this investigation. Concrete spe...

1. The globulins of both normal and diphtheria antitoxic serum exhibit chemically toward reagents the same reactions, being precipitated by magnesium sulphate and split up into fractions in precisely the same way. 2. All of the diphtheric antitoxic power of both normal and immunized serum is always carried by the globulin and its fractional precipitates. 3. During the fractional precipitation o...

The patient, a European boy, aged five years, had two or three attacks of vomiting without apparent cause on the 29th October. He was given a dose of castor oil on the morning of the 30th and according to his mother passed a stool normal in appearance. About 2 a.m. on the 31st October the boy was seized with an acute attack of pain of a colicky nature, and although considerably relieved by a sm...

BACKGROUND Regional anesthesia is widely used to perform different surgical procedures including those performed on the extremities. In this study, the anesthetic effects of adding intrathecal neostigmine or magnesium sulphate to bupivacaine in patients under lower extremities surgeries were assessed. MATERIALS AND METHODS In this double-blind randomized clinical trial, 90 patients, candidate...

OBJECTIVES To investigate the effects of magnesium sulphate on succinylcholine-induced fasciculation in patients during the induction of general anaesthesia. METHODS The double-blind randomised clinical trial was conducted in 2012 at Tohid and Besat Hospitals in Sanandaj, Iran, on patients who were candidates for surgery under general anaesthesia. Patients were selected and divided into two e...

Perioperative cerebral damage may be associated with surgery and anaesthesia. Pharmacological perioperative neuroprotection is associated with conflicting results. In this qualitative review of randomized controlled clinical trials on perioperative pharmacological brain neuroprotection, we report the effects of tested therapies on new postoperative neurological deficit, postoperative cognitive ...

INTRODUCTION The aim of the study is to evaluate the analgesic efficiency of perioperative magnesium sulphate infusion in patients undergoing laparoscopic cholecystectomy (LC). METHODS In a randomized, double-blind trial study, 83 patients were divided into two groups. Group MT received 50 mg/kg i.v. magnesium sulphate in 100 ml of 0.9% normal saline and Group T received the same volume of is...

BACKGROUND Magnesium sulphate is a neuroprotective agent that might improve outcome after aneurysmal subarachnoid haemorrhage by reducing the occurrence or improving the outcome of delayed cerebral ischaemia. We did a trial to test whether magnesium therapy improves outcome after aneurysmal subarachnoid haemorrhage. METHODS We did this phase 3 randomised, placebo-controlled trial in eight cen...

The foregoing experiments establish firmly the following facts. Subcutaneous or intramuscular injections of sodium oxalate in subtoxic doses, when administered to an animal which received a subminimal dose of magnesium sulphate, produce profound anesthesia and paralysis of long duration, although the usual effects of sodium oxalate alone are of a stimulating character. This fact is, in general,...

Carbachol and magnesium sulphate were used to increase the motility of the intestine in healthy volunteers. The effect was estimated by recording changes in abdominal sounds. Serum 5-hydroxytryptamine levels were assayed and found to be higher after gastrointestinal stimulation.
