Superantigens and Streptococcal Toxic Shock Syndrome

Superantigens produced by Streptococcus pyogenes have been implicated with streptococcal toxic shock syndrome (STSS). We analyzed 19 acute-phase serum samples for mitogenic activity from patients with severe streptococcal disease. The serum samples from two patients in the acute phase of STSS showed strong proliferative activity. Streptococcal mitogenic exotoxin (SME) Z-1 and streptococcal pyrogenic exotoxin (SPE)-J were identified in one patient with peritonitis who recovered after 2 weeks in intensive care. SMEZ-16 was found in a second patient who died on the day of admission. Sequential serum samples taken on day 3 after admission from patient 1 showed clearance of mitogenic activity but absence of neutralizing anti-SMEZ antibodies. Serum samples taken on day 9 from this patient showed evidence of seroconversion with high levels of anti-SMEZ antibodies that neutralized SMEZ-1 and 12 other SMEZ-variants. These results imply that a high level of SMEZ production by group A streptococcus is a causative event in the onset and subsequent severity of STSS

The Acid-catalyzed Dehydration of 2-(1-Cyclohexenyl)cyclohexanol

The dehydration of 2-(1-cyclohexenyl)cyclohexano1 (3) gave cyclohexylcyclohexenes, cyclohexylidenecyclohexane, cyclohexylidenecyclohexene, cyclohexylcyclohexadienes, cyclohexenylcyclohexenes, phenylcyclohexane, and dodecahydrodibenzofurans. The product distribution was quite sensitive to the solvents and catalysts employed
