Praval bhasma (PB; Coral calx) is a natural source of rich calcium widely used in traditional system of Indian medicine as a supplement in the treatment of variety of bone metabolic disorders associated with calcium deficiency. The present study was designed to investigate the inhibitory effects of Praval bhasma on the progress of bone loss induced by ovariectomy and concurrent calcium deficiency (CD-OVX).
Oyster extracts have been reported to have many bioactive peptides. But the function of oyster peptides produced by proteolysis is still unknown. In this study, the oligopeptide-enriched hydrolysates from oyster (Crassostrea gigas) were produced using the protease from Bacillus sp. SM98011 at laboratory level, and scaled up to pilot (100 L) and plant (1,000 L) levels with the same conditions. And the antitumor activity and immunostimulating effects of the oyster hydrolysates in BALB/c mice were investigated.

BACKGROUND: Graves' disease is an autoimmune disease that can affect a few patients with hyperthyroidism. In this case report, we demonstrated that Traditional Chinese Medicine (TCM) was effective for the patient with hyperthyroidism induced by Graves' disease. The patient also remained in the euthyroid state for several years after the treatment. SUBJECT AND SETTING: A 33-year-old woman had palpitations, fatigability, and weight loss and was diagnosed as having Graves' disease. Urticaria and itching skin appeared after she took an antithyroid drug.
To compare the chemical differences between the medicinal and cultured oyster shells, their chemical profiles were investigated. Using the ultra performance liquid chromatography-electron spraying ionization-mass spectrometry (UPLC-ESI-MS), combined with principal component analysis (PCA) and orthogonal projection to latent structures discriminant analysis (OPLS-DA), the discrimination of the chemical characteristics among the medicinal and cultured oyster shells was established. Moreover, the chemometric analysis revealed some potential key compounds.
