    Notes: A dose-response study was performed with three doses of colestipol, using postprandial serum bile acid levels to assess bile acid sequestering activity in 40 volunteers with asymptomatic hyperlipidaemia. Subjects who entered the study had total serum cholesterol concentrations greater than 220 mg/dl and triglyceride concentrations less than 200 mg/dl. They were randomly assigned to one of four parallel treatment groups: (a) placebo b.d., colestipol (as Colestid hydrochloride granules) 2.5 g b.d., (c) colestipol 5 g b.d., and (d) colestipol 7.5 g b.d. Subjects were maintained on a constant repeating solid diet throughout the 6-day study period, and colestipol was ingested 30 min before breakfast and dinner. No drug was administered on Days 1–3; baseline (pre-treatment) serum bile acid concentration profiles were determined on Day 3. The above treatments were given on Days 4–6, and total serum bile acid

    Notes: Summary The psychotomimetic active principles of the ancient aztec drug «Ololiuqui» (Rivea corymbosa (L.) Hall. f.) have been found to be alkaloids of the ergot type. Three of the components could be crystallized and identified, i.e. ergine (isolysergic acid amide), isoergine (Lysergic acid amide) and chanoclavin. The same alkaloids were found in the seeds of the related convolvulaceous vineI pomoea tricolor Cav.

    Notes: Summary Ergot alkaloids of the peptide type and their dihydro-derivatives can be converted reversibly in acid solution into isomeric compounds. They are characterised by the prefix ‘aci’, e.g. aci-ergotamine, aci-dihydro-ergotamine. The isomerisation takes place in the peptide part of the molecule.

    Does pertussis infection induce manifestation of allergy? (1993)
    Springer
    Journal of molecular medicine 71 (1993), S. 208-213

    Notes: Summary To evaluate whether pertussis induces the development of allergy, a prospective study was performed in 25 children aged 0.8–12.2 years. The patients underwent allergy diagnostics during pertussis infection and at a follow-up visit 8–14 months later. Diagnostic criteria included the medical history of the patients and their families, a modified skin prick test, measurement of serum IgE and radio-allergosorbent test screening for specific sensitizations. At the time of pertussis, serum IgE concentration in the study group was 62+ 30 kU/ml. At the follow-up visit, there was a significant increase in serum IgE to 137 ± 51 kU/ml, which was also significantly higher than IgE in an age-matched control group. Children at a significantly higher risk for developing IgE increase or new allergic sensitizations were those with a family history of allergy or potentially allergic disease in their personal history. Our results indicate that pertussis may induce IgE production in affected children.

    Solitary versus multiple cholesterol gallbladder stones (1993)

    Topics: Medicine
    Notes: Summary The development and growth pattern of solitary and multiple cholesterol gallbladder stones was defined using cholecystography in a prospective study of 48 patients whose initial cholecystograms indicated a stone-free gallbladder and who developed gallstones within the subsequent 5 years. Radiological observations performed over 365 patient-years were complemented by macroscopic examination, radiograms, scanning electron microscopy, and chemical analysis of gallstones from these and other patients obtained at cholecystectomy. Solitary gallstones were found to develop after a precursor phase of over 2 years during which free-floating crystal laminae of cholesterol formed. These laminae subsequently aggregated loosely and underwent external compaction and internal remodeling by movement of cholesterol molecules to form compact spheroids. A single lamina was observed to function as a nucleus for the development of a solitary stone shaped as an ellipsoid. About 10% of solitary stones were found to have a solitary pigment stone in their center. In contrast, multiple cholesterol gallstones formed without a precursor phase. Innumerable, very thin cholesterol crystals appeared which very abruptly aggregated to form spheres of up to 1 mm in diameter. Within 3 months a second aggregation took place in which these spheres coalesced to form mulberry stones. Mulberry stones in turn were transformed either to faceted stones (if many were present in the gallbladder) or to barrel stones (if few were present) over a period of 3 years. It is proposed that temporary occlusion of the cystic duct leads to supersaturation of bile with calcium bilirubinate and/or calcium carbonate which in turn promotes deposition of either or both of these calcium salts on the surface of single or multiple gallstones. For multiple gallstones, this process or the deposition of additional cholesterol crystals seals the gallstone surface and is followed by metamorphosis of the stone center.

    Interaction of electronic structure and nuclear dynamics on the S1 reaction surface for the ring opening of cyclohexadiene (2000)

    Notes: Abstract. For the ultrafast photoinduced ring opening of cyclohexadiene the S1 state plays a central role, providing the possibility to rapidly decay to the ground state. In this paper we follow the path of a wavepacket propagating in the reactive coordinate space of the S1 surface. We present a detailed analysis of the corresponding electronic and nuclear motions. With the help of a projection method and a normal-mode analysis, the vibrational modes driving the reaction might be detected experimentally.
