hi i had to redo the pulling together of old posts on the zinc vascular connection. here you go!

more on zinc
http://www.rowett.ac.uk/newsletter/Reso ... ticle4.pdf In this article, John Beattie describes how dietary zinc intake may influence vascular health and disease. He demonstrates that the development of vascular disease is accelerated in marginal zinc deficiency and investigates a mechanistic basis for this influence, possibly involving vascular smooth muscle structural proteins...
http://grande.nal.usda.gov/ibids/index. ... row=361901 Our data indicate that zinc is vital to vascular endothelial cell integrity, possibly by regulating signaling events to inhibit apoptotic cell death.

... -Zinc deficiency changes your iron metabolism.
i found an in vitro study; will look for more:

One consequence of zinc deficiency is an elevation in cell and tissue iron concentrations... The increase in cellular iron was associated with increased transferrin receptor 1 protein and mRNA levels and increased ferritin light chain expression...
...and i think i already linked to this before too:

an interesting crossover between vascular issues, ms, and zinc status
- small n, but whatever:
shortened link addedWilliams and colleagues compared the nutritional status of a group of 10 women with multiple sclerosis and pressure ulcers with 10 women free from any chronic wound. While the women had low normal values of several vitamins and trace elements suggesting very mild deficits, serum zinc levels were considerably less than normal ranges, suggesting a more significant deficiency. Balaji and Mosley treated a group of 50 patients with large vascular ulcers of the lower extremities and associated both zinc and vitamin C deficiency with delayed wound healing.

Iron and zinc status in multiple sclerosis patients with pressure sores.
Williams, C M : Lines, C M : McKay, E C
Measurements of weighted dietary intakes and plasma determinations of albumin, iron, zinc, ascorbic acid and TIBC were carried out on twenty female multiple sclerosis patients in a long-stay hospital for disabled people. The group included ten patients with a recent history of pressure sores, closely matched with ten patients without pressure sores. Mean daily intake of carbohydrate was found to be higher in the non-pressure sore group whilst intake of zinc was lower in this group. Intakes of all other nutrients were comparable between the two groups. For both groups, intakes of energy, folate, vitamin D, iron and zinc were less than recommended values. Mean plasma levels of albumin and iron were towards the lower limit of the normal range, whilst that for zinc was considerably less than the normal range. Plasma TIBC was slightly above the normal range. Levels of plasma iron and zinc were significantly lower in the pressure sore group. The data indicate that severely disabled hospitalized patients with multiple sclerosis may be at risk of poor nutritional status. The results suggest that in the presence of pressure sores, there are increased requirements for specific nutrients, notably zinc and iron. Consideration is given to the possible value of supplementation of these individuals.

Zinc Deficiency Induces Vascular Pro-Inflammatory Parameters Associated with NF-{kappa}B and PPAR Signaling
In the current study we hypothesized that vascular dysfunction and associated inflammatory events are activated during a zinc deficient state.
Zinc deficiency increased oxidative stress and NF-{kappa}B DNA binding activity, and induced COX-2 and E-selectin gene expression, as well as monocyte adhesion in cultured endothelial cells.
For example, rosiglitazone induced inflammatory genes (e.g., MCP-1) only during zinc deficiency, and adequate zinc was required for rosiglitazone to down-regulate pro-inflammatory markers such as iNOS.
hope you get a chance to address that zinc deficiency james! the average serum zinc level for healthy controls is 18.2 - 18.4 umol/L.
