Pharmacological investigation of salivary gland of Thais haemastoma (clench)
Toxicon, 1972The salivary gland extract of Thais haemastoma was found to be a powerful vasodilator and hypotensive agent. When the extract was administered i.v. to anaesthetized cats at a dose of 5–20 mg per kg (expressed in terms of the crude gland) it produced a sustained fall in the blood pressure and a distinct bradycardia.

Pharmacological Properties of Hypobranchial Gland of Thais haemastoma(Clench)
Journal of Pharmaceutical Sciences, 1971The aqueous extract of the hypobranchial glands of Thais haemastoma, administered intravenously to anesthetized cats at doses equivalent to 60–90 mg. of fresh gland/kg. body weight, produced an increase in the blood pressure accompanied by tachycardia.

Abstract. In the Azores the gastropod Thais haemastoma shows varying degrees of imposex, the induction of male sex characters in the female. It is inferred that imposex in T. haemastoma is caused by tributyltin (TBT) associated with boats using organotin‐based antifouling paints.

Metabolic Responses of the Estuarine Gastropod Thais haemastoma to Hypoxia
Physiological Zoology, 1987Chronic hypoxia tolerance of Thais haemastoma was inversely related to acclimation temperature but not to salinity. Oxyregulatory ability varied inversely with temperature and did not exhibit acclimation after 28 days' exposure to 53 mm Hg O₂. The oxygen consumption rate was lower after 28 days' exposure to hypoxia than under normoxia at 20 and 30 C ...

Choline esters and imidazole acids in extracts of the hypobranchial gland of Thais Haemastoma
Comparative and General Pharmacology, 19731. 1. Methanol and acetone extracts of the hypobranchial gland (dye-secreting area) of the two gasteropod molluscs Thais haemastoma and Thais haemastoma floridana contain large amounts of dihydromurexine (up to 12–17 mg. per g. fresh tissue) and senecioylcholine (up to 15–18 mg.

The cytochrome P-450 monooxygenase or mixed function oxidase (MFO) system is a widely distributed enzyme system involved in the detoxication of foreign organic compounds (xenobiotics) taken up by organisms. Increases in the activities of the MFO system, occur with exposure of the organism to organic xenobiotics and such responses in the field have been

Abstract Specific histopathological parameters have been proposed as good indicators of heavy-metal pollution. Hence the study of ultrastructural alterations in target organs from sentinel animals after heavy-metal exposure may provide a useful tool in understanding the cellular role in heavy-metal metabolism.

The relationship between individual energy budgets and genetic variability was examined in Thais haemastoma acclimated to 7.5, 20, and 35‰S (parts per thousand salinity) at 21 C. Energy budgets were determined by measuring rates of ingestion, absorption efficiencies, oxygen consumption, and ammonia and primary amine excretion.

Abstract Larvae of many shallow-water near-shore tropical gastropod species appear to have planktonic durations of several months or more and therefore may have great dispersal capabilities. To investigate physiological factors possibly related to length of planktonic life, this study documented the larval bioenergetics and carbon budgets for one ...
