In order to isolate T. spiralis premature muscle larvae, a mixed population of larvae at various periods of development was obtained by homogenization in PBS (with peptic digestion omitted) of infected mouse muscles isolated at day 20 postinfection. The homogenate was incubated 2 h at 37°C to allow the release of larvae from the tissue. The released larvae were separated by sedimentation and washing with PBS. 

A calorigenic action of thyroid hormones can also be demonstrated in tissues excised from animals with experimentally induced hyperthyroidism. In 1924, Rohrer demonstrated increased oxygen consumption in liver, kidney, and muscle isolated from mice which had been made hyperthyroid with desiccated thyroid. Most subsequent experiments have been performed with tissue sUces excised from other species, especially the rat. Differences in the metabolic responses of various tissues to thyroid stimulation have been ob.served, depending upon the species studied and the thyroid preparations used these differences will be discussed in the subsequent section. In contrast to the response of isolated tissues to thyroid hor-... 

The vasorelaxant effect of the EO of Mentha pulegium L. (Lamiaceae) was tested in tracheal and bladder smooth muscles isolated from rats. The EO induced relaxation in precontracted smooth muscles. Relaxing effects are likely to be correlated with the inhibition of Ca -entry. The effects are likely to be mediated with the main component pulegone (Soares et al., 2012). 

Other smooth muscles. Angiotensin evokes also a contraction of several smooth muscles including guinea-pig ileum (18) longitudinal smooth muscle isolated from guinea - pig ileum (13, 14), rat duodenum (36), uterus (18). 

HisN03,(CH3)3N + -CH2 CH0H CH2C00-. Isolated from skeletal muscle. It acts as a carrier for ethanoyl groups and fatty acyl groups across the mitochondrial membrane during the biosynthesis or oxidation of fatty acids. 

The posterior lobe of the pituitary, ie, the neurohypophysis, is under direct nervous control (1), unlike most other endocrine organs. The hormones stored in this gland are formed in hypothalamic nerve cells but pass through nerve stalks into the posterior pituitary. As early as 1895 it was found that pituitrin [50-57-7] an extract of the posterior lobe, raises blood pressure when injected (2), and that Pitocin [50-56-6] (Parke-Davis) causes contractions of smooth muscle, especially in the utems (3). Isolation of the active materials involved in these extracts is the result of work from several laboratories. Several highly active posterior pituitary extracts have been discovered (4), and it has been deterrnined that their biological activities result from peptide hormones, ie, low molecular weight substances not covalendy linked to proteins (qv) (5). 

The 9,11-azo analog of PGH2, compound A, is stable indefinitely and is substantially more active than PGH2 in stimulating muscle contraction in the isolated rabbit aorta strip. 

It resembles atropine in its range of activity but in particular types of action it may differ quantitatively thus its action on the pupil is equal to that of atropine but shorter in duration, and that is also true of its antagonisni to the effect of acetylcholine on the isolated perfused cat s COTt, but its activity on the salivary gland and the blood pressure of the. IS greater than that of atropine, while its action on smooth muscle...
