Zinc (Zn) consumption has increased in many populations either due to the increased intake of Zn-fortified foods as in the
USA or in agricultural food stuffs as in some Indian states during the last decade. Its excessive intake has been reported
to induce acute pancreatitis (AP) in many studies due to increase in oxidative stress that was further reported to cause Cu
and Mg deficiencies. This led us to design a modified poultry egg (MEΨ) enriched with Cu and Mg along with other antioxidants, and its efficacy on Zn-induced AP was studied in male Wistar rats.
In one set, the rats were fed on equacaloric semi-synthetic basal diet containing 20 mg Zn/kg diet (control, group I), and
Zn-induced AP-I diet and AP-II diet containing 40 and 80 mg Zn/kg diet (groups II and III) for 180 days, respectively. In
another set, the rats were initially fed on Zn-induced AP-I and AP-II diets for 90 days and then shifted to -mixed Zn-induced AP-I and AP-II diets in groups IIME and IIIME for another 90 days. At the end of the experiment, data displayed
increased serum and urinary Zn, Cu, and Mg levels in groups II and III rats, which were reduced and approached closer to control
group I after feeding in groups IIME and IIIME rats. Transmission electron microscopic studies of acinar cells revealed progressive dilation,
vesicularization, and degeneration of endoplasmic reticulum (ER), and decrease in zymogen granules (ZG) in groups II and III
rats in contrast to their curvilinear or concentric long parallel running cisternal profile of ER in control group I. The
treatment of helped in the restoration of the ER profile and ZG number, approaching closer to the control group I. The degree of recovery
was dependent upon the degree of toxicity caused by the amount of Zn given in the diet. The results of this study suggest
that -mixed diet can protect the acinar cells from the deleterious effects of Zn by decreasing the oxidative stress.

Excessive Zn but normal Cu and Mg in the staple food consumed by the people of Chandigarh (Union territory and capital of
Punjab and Haryana States of India) has been considered to be the major risk factor for the prevalence of obesity (33.15%)
and obesity-related diseases in this region. Therefore, in the present investigations, in obesity-related diseases, the status
of these minerals was estimated in their tissues, including hair, nails, and blood serum and urine, and compared with those
of normal subjects. They were grouped as: normal subjects in control Group A, middle-aged diabetics in Group DM, older diabetics in Group DO, and diabetics with osteoarthritis in Group D+ OA, osteoarthritis in Group OA and rheumatoid arthritis in Group RA, respectively.
The results evaluated in the order as: hair Zn, group D+OA>DM>OA>A (control)>RA>DO (p < 0.001); hair Cu, group A (control)>DM>OA>D+OA>DO>RA (p < 0.001); hair Mg, group A (control)>DM>OA>D+OA>RA>DO (p < 0.001, 0.01); hair Mn, group A (control)>RA>OA>D-OA>DM>DO (p < 0.001); nail Zn, group DM>D+OA>OA>A (control)>RA>DO (p < 0.001, 0.05); nail Cu, group A (control)>OA>DM>D+OA>RA>DO (p < 0.001); nail Mg, group A (control)>OA>DM>DO>D+OA >RA (p < 0.001); nail Mn, group A (control) >RA>OA>D+OA>DM>DO (p < 0.01); urine Zn, group DO>DM>D+OA>A (control)>RA>OA (p < 0.01); urine Cu, group RA>D+OA>DO>OA> DM>A (control) (p<0.001); urine Mg, group RA>OA>D+OA>DO>DM>A (control; p < 0.001); urine Mn, group DO>DM>OA>D+OA>RA>A (control; p < 0.001), respectively. The analysis of the mineral status in serum of diabetics further showed their highly significant
rise from lower mean age subgroup to higher mean age subgroup than their control counter parts (p < 0.001, 0.01, and 0.05) with coincident deficiencies of Cu, Mg, and Mn in their tissues. This study would be helpful considering
the status of minerals in these obesity-related diseases depending on the choice of the food consumed to improve the quality
of life and prognosis for the diseases. 相似文献
