Reference methods for quality control of vaccines usually require treatment of the samples before analysis. These procedures are expensive, time-consuming, unhealthy and require careful manipulation of the sample, making them a potential source of analytical errors. This work proposes a novel method
Yellow fever, an acute mosquito-borne viral haemorrhagic fever, is preventable by use of the live, attenuated 17D vaccine. The vaccine is used principally in tropical climates and is subject to potentially adverse conditions. Lyophilized vaccine without stabilizers deteriorates rapidly when exposed
A randomized placebo-controlled double-blind cross-over study was conducted in order to examine the effect of an aldose reductase inhibitor, sorbinil (100 mg daily for 4 weeks), on red cell sorbitol concentration and clinical and electrophysiological parameters of diabetic neuropathy. A total of 31
Flurbiprofen, a potent non-steroidal anti-inflammatory and antipyretic agent, was given as an intravenous infusion (2 mg/kg) followed by a bolus injection of 1 mg/kg six hours later. After drug administration body temperature and rumen contractions were slightly depressed, whereas urea values
The addition of D-glucose, D-galactose, or D-mannose to culture medium increased survival of heated Chinese hamster ovary cells in a concentration- and time-dependent manner. Heat protection by sugars was not immediate but required prior incubation in the sugar medium before hyperthermia. The degree
Ebola virus is a virulent pathogen that causes highly lethal hemorrhagic fever in human and non-human species. The rapid growth of this virus infection has made the scenario increasingly complicated to control the disease. Receptor viral matrix protein (VP40) is highly responsible for the
Verotoxin-producing Escherichia coli strains have been associated with acute hemorrhagic colitis since 1982. We have systematically investigated this pathogen in our laboratory, in all stool samples submitted for culture during a fourteen month period, by using MacConkey sorbitol agar to isolate non
BACKGROUND
Typhoid fever caused by Salmonella enterica serovar Typhi is endemic in developing countries. Its detection by culturing on specific media or serological methods like the Widal test is time consuming and/or less sensitive than the PCR technique. Here we apply a multiplex PCR dependent
The present study describes a case of laxative-induced rhabdomyolysis in an elderly patient. An 87-year-old woman was hospitalized for the onset of confusion, tremors, an inability to walk, and a fever that she had been experiencing for 36 hours. She often took high dosages of lactulose and sorbitol
We tried to isolate verotoxin-producing Escherichia coli (VTEC) on sorbitol-MacConkey (SMAC) agar and in part by the polymerase chain reaction (PCR) method from sporadic enteritis patients with bloody stools and intussusception patients who came to three pediatric clinics in the Fukuoka area from
Fructose-1,6-bisphosphatase (FBP1) deficiency is characterized by episodic acute crises of lactic acidosis and ketotic hypoglycemia, manifesting as hyperventilation, apneic spells, seizures, and/or coma. Acute crises are most common in early childhood; nearly half of affected children Chronic diarrhoea of the adult is defined as diarrhea during 30 days or longer. Frequent causes of chronic diarrhea in the immunocompetent adult without recent travel to developing countries are noninfectious processes, including laxatives misuse, diseases causing chronic maldigestion, osmotically
BACKGROUND
Ingestion of small amounts of elemental mercury is generally thought to be harmless. However, in 4 previously reported cases, ingested mercury became sequestered in the appendix, causing appendicitis in one. We present a case in which elemental mercury was administered as a
Twenty infants and young children with hereditary fructose intolerance (HFI) were admitted to hospital. None was diagnosed at admission. Referals were for vomiting of unknown aetiology (16X), pyloric stenosis or hiatus hernia (5X), toxic condition (3X), and hepatomegaly of unknown origin (5X).
OBJECTIVE
Non-O157 Shiga toxin-producing Escherichia coli (STEC) have emerged as an important public health problem. Outbreaks attributed to non-O157 STEC rarely are reported. In 1999, follow-up of routine surveillance reports of children with hemolytic- uremic syndrome (HUS) identified a small
