Several bronchodilator drugs commonly used in respiratory therapy contain sodium metabisulfite as an antioxidant preservative. When aerosolized, these agents may release the irritant gas SO2 as a result of bisulfite decomposition. We found that agents that contain bisulfites generated SO2 concentrations of 2.0 ppm and greater, while bronchodilator solutions without bisulfite did not. Such level...
One of Indonesia's forest products is porang tubers (Amorphophallus Oncophyllus). Porang tuber a food plant that has potential source glucomannan. Post-harvest processing one the main problems in obtaining optimal glucomannan levels tubers. This study aims to obtain high quality flour by increasing content flour.

Two experiments were conducted to evaluate potential detoxifying agents on growth of nursery pigs fed deoxynivalenol (DON)-contaminated diets. Naturally DON-contaminated wheat (6 mg/kg) was used to achieve desired DON levels. In a 21-d study, 238 pigs (13.4 ± 1.8 kg BW) were used in a completely randomized design with a 2 × 2 + 1 factorial arrangement. Diets were: 1) Positive control (PC; < 0.5...

Several screening methods for detecting sickling hemoglobins are presently used in the clinical laboratory (1-6). The present procedure depends on the insolubility of reduced hemoglobin S in a 2.24 mol/liter phosphate buffer. The commercially available “Sickledex” (Ortho Diagnostics, Raritan, N.J. 08869) is also thought to be based on this principle (6). Our method was compared with the standar...
background: successful therapy of leishmaniasis depends on effective cellular immune response. we evaluated the effectiveness of sodium selenite and zinc sulphate as known immunomodulator materials, in combination with glucantime® in treatment of cutaneous leishmaniasis lesions resulting from leishmania major in susceptible animal model. methods: thirty three female mice weighing 18-20 g at th...
