Marginal Zinc Deficiency Affects Biochemical and Physiological Parameters in Beef Heifer Calves
Engle, T.E.,Nockels, C.F.,Hossner, K.L.,Kimberling, C.V.,Toombs, R.E.,Yemm, R.S.,Weaber, D.L.,Johnson, A.B. Asian Australasian Association of Animal Productio 1997 Animal Bioscience Vol.10 No.5
A study detennined whether certain biochemical and physiological variables were altered during marginal Zn deficiency. Ten weaned crossbred Hereford Angus heifer calves, weighing $163{\pm}2kg$, were utilized. Five calves were fed a Zn - deficient (- Zn) brome-alfalfa hay diet containing 17 mg Zn/kg diet DM, and five calves were fed a Zn-adequate (+Zn) diet with 23 mg Zn/kg diet DM from $ZnSO_4$ added to the - Zn diet (total diet, 40 mg Zn/kg diet DM), for 32 d. At 21 d the - Zn calves had a reduction (p < .05) in feed efficiency. By 25 d, plasma Zn and alkaline phosphatase concentrations were reduced (p < .05) in the - Zn calves. Blood urea nitrogen, glucose, insulin, IGF-I, Cu plasma concentration and Zn and Cu concentrations of red blood cell (RBC) and liver were not altered (p > .05) by the - Zn diet through 25 d. In response to a single i. m. injection of dexamethasone (20 mg) on d 25, calves fed the two dietary Zn amounts showed no changes (p > .05) in plasma or RBC Zn and Cu concentrations, serum IGF-I, insulin, and glucose when measured at 6, 12, 24, 48, 72, and 96 h after injection. In response to an intradermal injection of phytohemagglutinin on d 30, cell mediated immune (CMI) response was reduced (p < .05) in the - Zn calves. These observations indicate that during a marginal Zn deficiency in calves, there was a decrease in feed efficiency, plasma Zn, serum alkaline phosphatase, and CMI response.

A 36-year-old male patient initially presented with hypertension, tinnitus, bilateral carotid masses, a right jugular foramen, and a periaortic arch mass with an elevated plasma dopamine level but an otherwise normal biochemical profile. On surveillance MRI 4 years after initial presentation, he was found to have a 2.2-cm T2 hyperintense lesion with arterial enhancement adjacent to the gallbladder, which demonstrated avidity on 68Ga-DOTATATE PET/CTand retrospectively on 18F-FDOPA PET/CT but was nonavid on 18F-FDG PET/CT. Biochemical work-up including plasma catecholamines, metanephrines, and chromogranin A levels were found to be within normal limits. This lesion was surgically resected and was confirmed to be a paraganglioma (PGL) originating from the gallbladder wall on histopathology. Pheochromocytoma (PHEO) and PGL are rare tumors of the autonomic nervous system. Succinate dehydrogenase subunit D (SDHD) pathogenic variants of the succinate dehydrogenase complex are usually involved in parasympathetic, extra-adrenal, multifocal head, and neck PGLs.We report an unusual location of PGL in the gallbladder associated with SDHD mutation which could present as a potential pitfall on 18F-FDOPA PET/CT as its normal excretion occurs through biliary system and gallbladder. This case highlights the superiority of 68Ga-DOTATATE in comparison to 18F-FDOPA and 18F-FDG in the detection of SDHD-related parasympathetic PGL.
