Patent number: 4954448Abstract: Silicic acid modulates (i.e. enhances or inhibits) adenylate cycloase activity. This effect appears to be a general one, inasmuch as the modulation has occurred in all tissues studied. The results suggest that silicic acid can be used in human and veterinary medicine to modulate hormone or neurotransmitter response. The results also indicate that silicic acid can be used to prevent, treat, or delay the onset of calcium-related bone disease, or to improve bone strength in an vertebrate having a bone strength less than desired.Type: GrantFiled: December 27, 1988Date of Patent: September 4, 1990Assignee: Nelson Research & Development CompanyInventors: Karl E.
