  • Atopic dermatitis (AD) is a chronically relapsing inflammatory skin disease that often has asthma and allergic rhinitis. Magnesium salts, the important component of minerals in Dead Sea water, are known to exhibit beneficial effects in inflammatory disease. Favorable effects of magnesium ions and sea water treated to the skin of patients with contact dermatitis have been reported. But histological and immunological investigations are insufficient. This study was performed to examine the inhibitory effect of magnesium-rich sea mineral water on the development of AD-like skin lesions in hairless mice. AD-like skin lesions are induced by the repeated application of 2,4-dinitrochlorobenzene (DNCB). Local application of magnesium-rich sea mineral water on hairless mice skin applied with DNCB inhibited the development of AD-like skin lesions as exemplified by a significant increase in skin hydration (p<0.01), and a decrease in epidermal water loss (p<0.01). Serum IgE level was also significantly decreased (p<0.01). These results suggest that magnesium-rich sea mineral water inhibits the development of DNCB-induced AD-like skin lesions in hairless mice. These observations indicate that magnesium-rich sea mineral water may be alternative and assistant substances for the management of AD.

  • The hemolysis index (HI) is semi-quantitative marker for hemolysis. Because the characteristics of the HI vary from one commercial platform to another, no standardization or harmonization of the HI is currently available. Specimens (N=40) randomly selected from clinical patients were artificially hemolyzed in vitro. The serum of the specimens was then diluted with a 20 mg/dL difference between 0~300 mg/dL based on serum hemoglobin measured using the XE-2100 hematology automation equipment (Sysmex, Japan). Diluted serum was measured using the Hitachi-7600 biochemical automation equipment (Hitachi, Japan) to differentiate between HI and serum hemoglobin. The data showed linearity between HI and serum hemoglobin and that HI 1 contained approximately 20 mg/dL of serum hemoglobin. To determine the blood rejection threshold, the HI was divided into three groups: HI 0~1, HI 4~6, HI 9~15. After another batch of clinical specimens (N=40) was measured using a Hitachi-7600 (Hitachi, Japan), each specimen was moved forward and backward with the piston of the syringe to induce an artificial in vitro hemolysis, then measured again with a Hitachi-7600 (Hitachi, Japan). The percentage difference between the three groups was analyzed by ANOVA or the Kruskal-Wallis test. In the post-test, there were significant differences between the HI 0~1 and the HI 5~6: Glucose, creatinine, total protein, AST, direct bilirubin, uric acid, phosphorus, triglyceride, LDH, CPK, Magnesium, and potassium levels. Because many clinical tests differed significantly, the threshold for hemolysis could be appropriate for HI 5 (serum hemoglobin 100 mg/dL).

  • Objective: Combination of two stressors on alteration of mineral footprints in animals needs due attention to meet maximum production and welfare, particularly in grazing sheep. This study tested whether ewes (Ovis aries) exposed to water deprivation and thermal-humidity stressors had altered mineral footprints in their wool, serum, urine, and feces. Methods: Nine ewes (age = 3 years; mean body weight = 41±3.5 kg) were divided among a control group with free access to water, and treatment groups with water deprivation lasting either 2 h (2hWD) or 3 h (3hWD) after feeding. Using a 3×3 Latin square design, animals were assigned to treatment groups for three sampling periods of 21 days each (n = 9). Blood was collected by jugular venipuncture. Wool was collected at the end of periods 2 and 3. Metabolic crates designed with metal grated floors were used for urine and feces collection. We measured sodium (Na), magnesium (Mg), phosphorus (P), chloride (Cl), calcium (Ca), manganese (Mn), copper (Cu), iron (Fe), and zinc (Zn). Results: The wool mineral levels did not differ between the treatment groups, although K was marginally lower (p = 0.10) in the 2hWD group. The serum and urine mineral levels did not differ between the treatments (p>0.05). Fecal K was significantly lower in the 2hWD group than in the other groups (p≤0.05). Conclusion: In conclusion, water deprivation and thermal-humidity exposure altered the excretion of K, but not of other minerals, in the wool, urine, feces, or serum of ewes. Thus, no additional mineral supplementation is needed for water deprived ewes during thermalhumidity exposure.

  • The effect of selenium and vitamin E on the incidence of retained fetal membranes(RFM) was evaluated in dairy cows raised in Kyonggi-do province from July through September 1985. Sodium selenite(0.1mg/kg of body weight) and vitamin E (1,000 IU) were simultaneously injected 21 days prior to the expected calving day to Holstein cows and the incidence in the treated group was compared with that in the non-treated control group. Serum levels of selenium, vitamin E, calcium, inorganic phosphorus and magnesium were also determined in the treated and the non-treated groups to compare the status of vitamin E and other minerals during periparturient period in the cows with RFM and the normal ones. The incidence of RFM was 34.5% in cows of the non-treated group (29 heads), whereas it was significantly reduced to 9.7% in cows of the treated group (31 heads) (p<0.05). Data for serum mineral concentrations showed that the prepartal inorganic phosphorus concentration was significantly lower in the RFM than in the not-retained group(p<0.01). As a result, the prepartal Ca/P ratio was significantly higher in the RFM group(p<0.01). It appears that a single injection of 0.1mg of sodium selenite per kg body weight and 1,000 IU of vitamin E 21 days prior to the expected calving day is an effective prophylactic for prevention of RFM, and that RFM may be related to imbalances in calcium and phosphorus metabolism.

  • The toxic effects of pentachlorophenol (PCP) on haematological parameters in olive flounder (Paralichthys olivaceus) after chronic exposure to dietary PCP (0.1, 0.5 and 1.0 mg/kg diet) for 2, 4 and 6 weeks were studied. A significant decrease in total RBC count, haemoglobin concentration and hematocrit value was noted in fish exposed to PCP compared to the non-exposed fish. The PCP treatment group showed significantly lower concentration of serum total protein and albumin, and significantly higher serum chloride, magnesium and total bilirubin levels compared with those in the control group. However, PCP had no major effects on serum glucose, total cholesterol, phosphate and calcium ions in flounder. These results demonstrated that PCP have induced adverse haematological impacts in the olive flounder, Paralichthys olivaceus. Because we found damages in blood-forming function and disruption in blood homeostasis due to chronic exposure to PCP, it is needed to develop further experimental studies for the risk assessment of this environmental pollutant.

  • A proteolytic enzyme was extracted from Sarcodon aspratus (Berk) S. Ito by percolation method. Proteolytic activity of the extracted proteolytic enzyme (SAP) was compared with several digestives containing proteolytic enzymes. Potency of SAP was higher than that of the other digestives except for protease. The optimum pH ranse of SAP was similar to that of pancveatin and protease. SAP was more stable than pancreatin and protease under various temperature, alkaline pH, and metal ions. Bovine serum albumin hydrolysing activity of SAP was equivalent to that of pancreatin and protease in small intestine of rats. SAP demonstrated lower adsorption to antacids than pancreatin and protease. Among the mixtures of SAP and several antacids, magnesium oxide-SAP showed the highest proteolytic activity.

  • A miniature schnauzer (8 years old, male castrated), diagnosed as diabetes mellitus 6 months ahead, were referred to the Veterinary Medical Teaching Hospital of our University with hindlimb stiffness, facial rubbing and tetany. Serum chemistry showed severe hypocalcemia, hypomagnesemia, and measured iPTH (intact pharathyroid hormone) concentration was low (< 3.0 pmol/L). Consistent rate injection of calcium gluconate (282 mg/kg over 30 min) resulted in prompt relief of the tetany. Then typical treatment for hypoparathyroidism (calcium gluconate and dihydrotachysterol per os) with magnesium administration could control the neuromuscular signs. Diabetes mellitus is being controlled by insulin therapy and prescription diet. Hypomagnesemia in diabetic dog may be induced hypoparathyrodism.

  • Minerals are individual of the components of foods and are not produced in the body but essential for best possible health. Several essential metals are vital for the appropriate performance of various enzymes, transcriptional factors and proteins that are essential in various biochemical paths. Metals like zinc (Zn), magnesium (Mg), and manganese (Mn) are cofactors of hundreds of enzymes. Zn is involved in the synthesis and secretion of insulin from the pancreatic ${\beta}-cells$. Chromium (Cr) increases the insulin receptors activity on target tissues, mainly in muscle cells. Insulin hormone is required to maintain the blood glucose amount in normal range. Continual increase of blood serum glucose level leads to marked chronic hyperglycemia or diabetes mellitus. Deficiency of insulin or its resistance, blood glucose level exceeds the upper limit of the common range of 126 mg/dl. Poor glucose control and diabetes changes the levels of essential trace elements such as Zn, Mg, Mn, Cr, iron etc. by rising urinary excretion and their related decrease in the blood. The aim of this article to discusses the important roles of essential trace elements in particular perspective of type 2 diabetes.

  • The blood components of not-young (young antler) were examined in the Red Deer. Blood samples were collected from the antler and jugular veins respectively. The hematological and serum chemical values were as follows; 1. RBC count of not-hyul (young antler blood) was significantly higher than that of jugular vein blood (p<0.05). However, fibrinogen concentration of rook hyul was significantly lower than that of jugular vein blood (p<0.01). WBC counts packed cell volume (PCV) and total protein fro) were not significant between nolo-hyul and jugular vein blood. 2. The concentration of phosphorous and magnesium of not-hyul were significantly higher than those of jugular vein blood (p<0.05). Albumin and glutamic oxaloacetic transaminase (GOT) of nolo-hyul were higher than those of jugular vein blood. But globulin and calcium concentration of not-hyul were lower than those of jugular vein blood. Blood urea nitrogen BUN) of rook-hyul was not significant when compared with that of jugular vein blood.

  • We experienced a case of partial DiGeorge syndrome in a $35^{+5}$ week premature female infant presented with micrognathia, fish-shaped mouth, beaked nose, nasal regurgitation, obstructive sleep apnea, velopharyngeal insufficiency and late onset hypocalcemic seizures. The chromosome 22q11 microdeletion was found by the FISH method. The lab findings showed serum calcium level of 4.4 mg/dL, ionized calcium level of 0.49 mg/dL, phosphorous level of 7.5 mg/dL, magnesium level of 1.3 mg/dL and PTH-RIA level of <1 pq/mL. Initial treatment was done with 10% calcium gluconate infusion and magnesium sulfate followed by oral calcium gluconate and low phosphorousformula milk feeding. The serum calcium level was normalized in 6 days. Nasal regurgitation, desaturation with obstructive sleep apnea continued. T-cell functions & numbers(CD 3, CD 4, CD 8)were decreased but Ig G/A/M levels were normal. No visible signs of thymus shadow were seen in either chest X-ray & chest MRI. Electrocardiography and echocardiography showed normal heart. Kidney ultrasonographby showed right side mild hydronephrosis. Neurosonography was normal but EEG showed electrical partial seizure. Hearing assessment by BERA showed mild to moderate hearing impairment. Velopharyngoplasty is scheduled for further treatment. A brief review of literature was made.
