Hematochezia in a Child With Heiner Syndrome.

Heiner syndrome (HS) is a food hypersensitivity disease that is mostly caused by cow's milk. The main features may include chronic or recurrent respiratory syndromes, pulmonary infiltrates on radiography, and even pulmonary hemosiderosis. However, gastrointestinal symptoms are rare in HS, which can lead to a misdiagnosis when the chief complaint is about the gastrointestinal system.

[Studies on quality control methods of nuxvomica].

Two quality control methods of nuxvomica were established for mutual. By selecting the appropriate measuring wavelength or wavelength range, the contents of strychnine and brucine in nuxvomica were determined without any preliminary separation by a new rapid spectrophotometry and a multi-wavelength linear regression spectrophotometry and with a computer program. The linear range of strychnine measured was 8.

[Ratio spectrophotometry and its application to assay of compound pharmacy preparations].

The present paper is to study ratio spectrophotometry for its application to the assay of compound pharmacy preparations. According to the feature of ratio spectra, the wavelength pair was selected at the peak point or valley point of ratio spectra to establish ratio spectrophotometry for the determination of Co-Chlorzoxazone tablet and injection of caffeine and sodium benzoate. The average recoveries and relative standard deviations for Chlorzoxazone and paracetamol were 100.
