The recent epidemic of cholera on the Pacific Ocean atoll of Tarawa, Gilbert Islands renewed interest in the use of coconut water as a rehydration fluid. Fifty-one samples of coconut water from Tarawa were analysed for a variety of constituents to assess its potential usefulness in the oral and parenteral rehydration of patients with cholera and other severe forms of gastroenteritis. Compared to oral rehydration fluids known to be effective in cholera, coconut water was found to have adequate potassium and glucose content, however was relatively deficient in sodium, chloride and bicarbonate. The addition of table salt to the coconut water is suggested to compensate for the sodium and chloride deficiency. In areas of the world where coconuts are plentiful, the advantages of sterility, availability and acceptability make coconut water theoretically feasible for the oral rehydration of patients with severe gastroenteritis when conventional fluids are unavailable.

The leader RNA sequence was determined for two pig coronaviruses, transmissible gastroenteritis virus (TGEV), and porcine respiratory coronavirus (PRCV). Primer extension, of a synthetic oligonucleotide complementary to the 5' end of the nucleoprotein gene of TGEV was used to produce a single-stranded DNA copy of the leader RNA from the nucleoprotein mRNA species from TGEV and PRCV, the sequences of which were determined by Maxam and Gilbert cleavage. Northern blot analysis, using a synthetic oligonucleotide complementary to the leader RNA, showed that the leader RNA sequence was present on all of the subgenomic mRNA species. The porcine coronavirus leader RNA sequences were compared to each other and to published coronavirus leader RNA sequences. Sequence homologies and secondary structure similarities were identified that may play a role in the biological function of these RNA sequences.

cDNA clones mapping within the first 2601 bases of the 3' end of the porcine transmissible gastroenteritis corona-virus (TGEV) genome were sequenced by the method of Maxam and Gilbert and an open reading frame yielding a protein having properties of the matrix (M or E1) protein was identified. It is positioned at the 5' side of the nucleocapsid (N) gene from which it is separated by an intergenic stretch of 12 bases. The deduced M protein comprises 262 amino acids, has a molecular weight of 29,544, is moderately hydrophobic, and has a net charge of +7 at neutral pH. Thirty-four percent of its amino acid sequence is homologous with the M protein of the bovine coronavirus (BCV), 32% with that of the mouse hepatitis coronavirus (MHV), and 19% with that of the avian infectious bronchitis coronavirus (IBV). Judging from alignment with the BCV, MHV, and IBV M proteins, the amino terminus of the TGEV M protein extends 54 amino acids from the virion envelope which compares with only 28 for BCV, 26 for MHV, and 21 for IBV. Eleven of the sixteen amino-terminal amino acids are hydrophobic and the positions of charged amino acids around this sequence suggest that the first 16 amino acids comprise a potentially cleavable signal peptide for membrane insertion. A similar sequence is not found in the M proteins of BCV, MHV, or IBV. When mRNA from infected cells, or RNA prepared by in vitro transcription of the reconstructed M gene, was translated in vitro in the presence of microsomes, the M protein became translocated and glycosylated. When a protein without the amino-terminal signal peptide was made by translating a truncated version of the M gene transcript, some translocation and glycosylation also occurred suggesting that the amino-terminal signal peptide on the TGEV M protein is not an absolute requirement for membrane translocation. Interestingly, the amino-terminal peptide did not appear to be cleaved during in vitro translation in the presence of microsomes suggesting that a step in virion assembly may be required for proper exposure of the cleavage site to the signal peptidase.

The 3' end of the 20-kb genome of the Purdue strain of porcine transmissible gastroenteritis coronavirus (TGEV) was copied into cDNA after priming with oligo(dT) and the double-stranded product was cloned into the PstI site of the pUC9 vector. One clone of 2.0-kb contained part of the poly(A) tail and was sequenced in its entirety using the chemical method of Maxam and Gilbert. Another clone of 0.7 kb also contained part of the poly(A) tail and was sequenced in part to confirm the primary structure of the most 3' end of the genome. Two potential, nonoverlapping genes were identified within the 3'-terminal 1663-base sequence from an examination of open reading frames. The first gene encodes a 382-amino acid protein of 43,426 mol wt, that is the apparent nucleocapsid protein on the basis of size, chemical properties, and amino acid sequence homology with other coronavirus nucleocapsid proteins. It is flanked on its 5' side by at least part of the matrix protein gene. The second encodes a hypothetical 78-amino acid protein of 9101 mol wt that is hydrophobic at both ends. A 3'-proximal noncoding sequence of 276 bases was also determined and a conserved stretch of 9 nucleotides near the poly(A) tail was found to be common among TGEV, the mouse hepatitis coronavirus, and the avian infectious bronchitis coronavirus.

Crigler-Najjar syndrome type II is caused by mutations in the UGT1A1 gene resulting in severely reduced hepatic activity of UDP-glucoronyltransferase - an enzyme required to convert bilirubin into a more soluble form that can then be removed from the body. Absence or severe deficiency of this enzyme can lead to bilirubin accumulation in the body resulting in yellow skin and eyes (jaundice). The earliest signs of this disease can be apparent in the neonatal period. Patients with Crigglar-Najjar syndrome type II respond to phenobarbital therapy which decreases their chances of getting bilirubinemia by 60-70% in 3 weeks. A 17 years old boy presented with the complaint of gastroenteritis. On examination, he was jaundiced and his parents reported that it has been present since birth. He was admitted in the hospital with the differential diagnosis of Gilbert syndrome, but later it was found that the unconjugated bilirubin levels were higher than those required for Gilbert's criteria. We report, herein, an extremely rare case of Crigler-Najjar syndrome type II and how the patient responded to phenobarbital therapy. Periods of fasting, stress and any kind of illness can worsen unconjugated hyperbilirubinemia leading to complications like kernicterus, so higher levels of unconjugated bilirubin should be addressed immediately and the patient along with his/her family should be educated about this disease.
