Expanding the scope of methylation-sensitive restriction enzyme (MSRE) PCR for forensic identification of body fluids through the novel use of methylation-dependent restriction enzymes (MDRE) and the combination of autosomal and Y-chromosomal markers.

Methylation-sensitive/-dependent restriction enzyme (MSRE/MDRE) PCR can be performed to detect hypomethylated or hypermethylated CpG sites. With the combined use of different tissue-specific CpG markers, MSRE/MDRE-PCR leads to tissue-specific methylation patterns (TSMPs), enabling the correlation of DNA samples to their source tissue. MSRE/MDRE assays can use the same platform as forensic STR typing and offer many advantages in the field of forensic body fluid detection.

Mechanism of kinin release during experimental acute pancreatitis in rats: evidence for pro- as well as anti-inflammatory roles of oedema formation.

1 Kinin B(2) receptor antagonists or tissue kallikrein (t-KK) inhibitors prevent oedema formation and associated sequelae in caerulein-induced pancreatitis in the rat. We have now further investigated the mechanism of kinin generation in the pancreas. 2 Kinins were elevated in the pancreatic tissue already before oedema formation became manifest.

Severe hypoxia inhibits prostaglandin I(2) biosynthesis and vasodilatory responses induced by ionophore A23187 in the isolated rabbit ear.

The present study was designed to test the hypothesis that lack of oxygen in severely hypoxic tissue may inhibit arachidonic acid oxygenation and thereby result in an inhibition of eicosanoid synthesis. Hypoxia was induced in the isolated rabbit ear, and arachidonate metabolism and peripheral resistance of the preparation were monitored simultaneously. Severe hypoxia completely inhibited the biosynthesis of prostaglandin I(2) induced by ionophore A23187 and converted the vasodilatory response observed under normoxia into vasoconstriction.
