Objective: Milk is the first and continued source of ingested Vitamin D. Extensive studies have been carried out in humans measuring Vitamin D in lactating mothers but to date few values have been obtained for milk of non-human primates and none for rhesus monkeys. Consequently. we have determined Vitamin D and antirachitic activity (ARA) in milk samples obtained from 21 rhesus monkeys.
Methods: Lactating dams were sampled by hand-stripping. 25(OH)D2, Vitamin D2, 25(OH)D3, Vitamin D3 and ARA were assessed in foremilk using LC-MS/MS techniques.
Results: 25(OH)D2 and Vitamin D2 were below detectible limits (<0.5 ng/g), 25(OH) D3 =4.2 ± 1.8 ng/ml, Vitamin D3 = 6.1 ± 3.1 ng/ml and ARA = 1080 ± 480 IU/L.
Conclusion: This is the first report of content of Vitamin D and ARA activity in foremilk of the rhesus monkey and can serve as a reference for future studies.
期刊介绍：
The Puerto Rico Health Sciences Journal (PRHSJ) is the scientific journal of the University of Puerto Rico Medical Sciences Campus. It was founded in 1982 as a vehicle for the publication of reports on scientific research conducted in-campus, Puerto Rico and abroad. All published work is original and peer-reviewed. The PRHSJ is included in PubMed/Medline, SCOPUS, Latindex, EBSCO, SHERPA/RoMEO, Science Citation Index Expanded (SciSearch®) and Journal Citation Reports/Science Edition. All papers are published both online and in hard copy. From its beginning, the PRHSJ is being published regularly four times a year. The scope of the journal includes a range of medical, dental, public health, pharmaceutical and biosocial sciences research. The journal publishes full-length articles, brief reports, special articles, reviews, editorials, case reports, clinical images, and letters arising from published material.
