The APS Journal Legacy Content is the corpus of 100 years of historical scientific research from the American Physiological Society research journals. This package goes back to the first issue of each of the APS journals including the American Journal of Physiology, first published in 1898. The full text scanned images of the printed pages are easily searchable. Downloads quickly in PDF format.
Thirty-eight normal volunteers and 10 patients with untreated thyrotoxicosis were each given 0.5 ml of Lugol's solution daily for 10 days. On days 0, 5, 10, 15 and 20, serum levels of T4, free T4, T3 and TSH (by sensitive immunoradiometric assay) were measured. In normal subjects, the serum concentrations of free T4 declined significantly at day 10 while TSH levels were significantly increased at days 5, 10 and 15. Serum levels of T4 and T3 did not change significantly. All the observed changes took place within the limits of normal ranges for the hormones mentioned. In contrast, in the thyrotoxic subjects, both T4 and T3 were significantly decreased at days 5 and 10, while serum TSH remained below detection limit (0.14 mU/l) throughout the study. Short exposure to excessive iodide in normal subjects affects T4 and T3 release and this effect could be partially overcome by compensatory increase in TSH. In thyrotoxicosis, lack of compensatory increase in TSH results in rapid decreases in T4 and T3 levels. The integrity of the hypothalamo-pituitary-thyroidal axis may be effectively assessed by measuring TSH response to iodide suppression, using a highly sensitive immunoradiometric assay.
The effects of trialkyltin compounds on the colchicine‐binding activity and the in vitro polymerisation of rat brain tubulin have been investigated. Trialkyltins at concentrations between 10 and 100 μM inhibited the colchicine‐binding activity of purified tubulin preparations derived from rat brain. Viscometric studies have shown that the same concentrations of trialkyltins also inhibited the in vitro polymerisation of tubulin. Both the effects were found to be concentration dependent. However, trialkyltins did not interfere with the in vitro preassembled microtubules. The reasons which are believed to explain the inhibitory effects of these compounds are discussed.

The majority of Chinese males with schizophrenia and maintained on antipsychotic drugs in the outpatient clinic had sub-optimal erectile function. Psychological management was the treatment of choice for their dysfunction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
