The influences of chloride-free components of the cement additive: triethanolamine, triisopropanolamine, sodium hyposulfite and calcium gluconate on the 1d, 3d and 28d compressive strength of cement were investigated by response surface methodology. It found the early strength activators, triethanolamine and sodium hyposulfite could enhance the 1d strength of cement effectively but they did not contribute to the 3d strength enhancement, and further their interaction was able to decrease the 28d strength of cement. Calcium gluconate was not that effective for the strength enhancement on 3 and 28 days when it's simply dosed. However the interaction effect of calcium gluconate with triisopropanolamine could strongly favor the strength enhancement of cement after 3 days. Results indicated it was necessary to focus attention on the potential interactions among the chemical components. And for the concern of four chemicals studied in this paper, it was feasible to formulated a kind of chloride-free cement additive that can be effective for the early strength of cement and its the strength after 3 days.

A 3,480 g male neonate showed tachypnea symptom with a serum ionized calcium level of 0.66 mmol/L by routine clinical analysis. He was injected calcium gluconate intravenously through femoral vein catheter to treat the hypocalcemia. On second day after the injection, he started to show erythema in the flank area. The lesion became firm and changed into whitish crust consist of small crystals. Abdominal X-ray and ultrasonography showed the accumulation of calcium deposit in the subcutaneous layer of the lesion. Surgical debridement was performed to remove the crust with calcium deposit and acellular fish skin graft rich in omega-3 (Kerecis) was applied to the defect site for secondary intention of the defect wound. After 2 months, the skin and soft tissue defect were fully covered with healthy normal skin without depression or contracture. This report is a first case of iatrogenic calcinosis cutis without extravasation symptom.

This study was performed to investigate the effects of calcium administration on the blood coagulation mechanism through APTT in the calf. Five male calves (70~90 kg) were used in this experiment. In the control group, heparinized normal saline (1 IU/kg/min) had been infusing into the jugular vein for 100 minutes. For the analysis of calcium effects on the APTT, the same solutions had been infusing during the first 40 minutes, subsequently the solution including calcium gluconate (3.3 mg/ml/min) had been infusing for 60 minutes. Blood samples were serially collected every 10 minutes for the APTT and platelets count and every 20 minutes for the calicum level during the infusion. In the calcium-treated group, after 70 minutes the APTT ratio (APTT heparin/APTT baseline) was higher than the therapeutic range. APTT was significantly increased at 50, 60 and 70 minutes in the calcium-treated group as compared to the control group (p<0.01). In the control group, calcium level was decreased significantly after heparin infusion (p<0.01). The platelet count was gradually decreased without significant variation in the both control and calcium-treated groups. These results suggested that APTT is slightly increased in combined heparin and calcium administration.

D-sorbitol을 첨가한 배지에서 G. melanogenus를 배양하였을 때에 D-sorbitold은 L-sorbose를 거쳐 2 keto-L-gulonic acid로 전환되었다. G. cerinus를 D-sorbitol 대신에 포도당을 첨가하여 준 배지에서 배양하였을 때에 포도당은 2-keto-D-gluconic acid, 5-keto-D-gluconic acid, 2.5 diketo-D-gluconic acid로 산화되었다. 2,5-diketo-D-gluconic acid는 포도당이 2-keto-D-gluconic acid를 거쳐 생성되는 것으로 확인되었다. 배양액에 첨가하여 준 탄산칼슘의 양을 증가시키면 5-keto-D-gluconate의 생성이 증가하였고, 탄산칼슘대신에 다른염기를 배양액에 가하여 주었을 때는 2keto-D-gliconate만 생성되었다.

저칼슘혈증은 신생아에서 흔하게 발견되며 대개 정맥 내 칼슘 투여를 통해 교정할 수 있다. 이 과정에서 발생할 수 있는 의인성 피부 석회화증은 칼슘 제제의 정맥 투여에 기인하는 것으로 알려져 있다. 저자들은 칼슘 글루코네이트의 혈관 외 유출로 인하여 신생아의 상지나 하지를 침범한 피부 석회화증 3예를 보고하고자 한다. 신생아 집중치료실에서 칼슘 글루코네이트의 정맥 내 투여와 관련하여 발생한 경화성 피부 결절을 보이는 생후 2주 여아, 생후 4주 남아 및 여아, 총 3명의 신생아가 협진 의뢰되었다. 초기 발견 후 각각 3주, 4주, 6개월에 방사선 사진 및 신체 검진상 만져지는 결절과 석회화의 완전한 관해가 이루어졌다. 또한 3명 모두에게서 점진적인 치유양상을 보였으며 기능적, 미용적 합병증은 발생하지 않았다. 환자들의 일반 양성 질환에 대한 인식이 높아짐에 따라 의인성 피부 석회침착증의 조기 진단을 내리고, 질환에 대한 충분한 설명과 이해를 바탕으로 불필요한 치료를 피함으로써 의료 과실 분쟁을 줄일 수 있을 것으로 생각된다.

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.

이번 연구에서는 천연추출물인 ${\beta}$-gluconsan calcium이 구강암 세포의 증식과 사멸에 미치는 영향을 평가하고자 하였으며, 다음과 같은 결론을 얻었다. ${\beta}$-gluconsan calcium 0.5 mg/ml 처리군에서 세포수의 감소와 형태 변화가 관찰되었으며, 0.75, 1 mg/ml에서는 거의 모든 세포가 사멸하였다. ${\beta}$-gluconsan calcium을 농도별로 처리한 결과, YD-10B 세포수가 농도 의존적으로 감소하였으며(p<0.05), MTT 분석 결과, ${\beta}$-gluconsan calcium 처리한 군은 아무것도 처리하지 않은 군에 비해 모두 세포 활성이 저하되었다(p<0.05). 이상의 결과들을 종합해 보았을 때, polycan과 calcium gluconate 복합제인 ${\beta}$-gluconsan calcium은 구강암 세포의 성장 억제에 효과가 있는 것으로 생각된다.

The physical method used to prevent a landslide has the risk of environmental pollution. Calcite forming bacteria (CFB) have been received increasing attention as a novel and environmental friendly strategy for the soil improvement. In this study, we selected 11 CFB strains with high calcite production. We also examined survivability and calcite productivity of the strains under various stress conditions to select strains with high resistance to various stresses. Two strains was selected by environment stress. Sphingobacterium sp. KJ-32 and Viridibacillus arenosi B-25 precipitate calcite more than other strains at pH 5 and $15^{\circ}C$ respectively. Bio-consolidated soil cakes were made using various calcium salts (calcium chloride, calcium acetate, calcium lactate, calcium gluconate) with mixed culture of 2 strains. Among them, the calcite made using calcium chloride was the largest. These observations demonstrate that this bio-consolidation technology has the potential for eco-friendly prevention of landslide and soil improvement.
