Qualitative Comparison between Lactase Preparations (3)

Effect of lactase preparations in asymptomatic individuals with lactase deficiency--gastric digestion of lactose and breath hydrogen analysis.

We compared two lactase preparations derived from Aspergillus orizae (AOL) and Penicillinase multicolor (PML) for stability in the stomach and overall enzymatic activity in 10 asymptomatic subjects with lactase deficiency. The subjects were given 10,000 FCC units of either AOL or PML 30 min prior to or simultaneously with 300 ml of milk. Gastric juice was withdrawn through a nasogastric tube im...

Comparison of Two Propylthiouracil Preparations in Treatment of Toxic Goiter

In order to compare the effect of propylthiouracil (PTU) of Iran Hormone Co. and that of Dr. Herbrand KG, Germany, 28 patients with toxic goiter entered this study. Each patient received 200 mg PTU daily for the first 4 weeks and 50 mg daily thereafter. 17 patients received PTU from Iran Hormone (group 1) and 111 took PTU from Germany (group 2). T4, T3 and TSH by RIA and resine T3, uptake were ...

Odorant responses of Xenopus laevis tadpole olfactory neurons: a comparison between preparations.

We used a slice preparation of the olfactory epithelium of Xenopus laevis tadpoles to record odorant responses of olfactory receptor neurons (ORNs) and compared these to odorant responses recorded in isolated ORNs. The maximum recording time in the slice was considerably longer than in isolated ORNs, which is essential when many odorants are to be tested. No odorant-induced responses could be o...

Nutrients, phytochemicals and bioactivity of wild Roman chamomile: a comparison between the herb and its preparations.

Roman chamomile, Chamaemelum nobile L. (Asteraceae), has been used for medicinal applications, mainly through oral dosage forms (decoctions and infusions). Herein, the nutritional characterisation of C. nobile was performed, and herbal material and its decoction and infusion were submitted to an analysis of phytochemicals and bioactivity evaluation. The antioxidant activity was determined by fr...
