The purpose of this study is to propose new estimation method of unit cement content in hardened concrete. In general, the quantity of cement in hardened concrete is tested by hydrochlonic acid dissolving cement paste, however, hydrochloric acid dissolves sea shell contained in sea sand and lime stone in concrete. Therefore, the tested cement content is apt to estimate greater than actual cement content. The sodium gluconate solution dissolves only cement in concrete, it is hard to dissolve sea shell and lime stone as CaCo3. The effects of the quantity, concentration and temperature of sodium gluconate solution, the ignition temperature, the ignition loss of cement on the cement content and the percentage of dissolution of cement were investigated to establish a test method. From the results of these tests, the fundamental test method for cement content of hardened concrete by sodium gluconate is proposed.

Celluloytic bacteria, -Gram positive, Gram negative and actionmycetes-were used to study their catabolic pathways of carbohydrate. It was found that Embden-Meyerhof-Parnas(EMP) pathway and hexose monophosphate(MHP) shunt were operated in Cellulomonase sp. CS1-1, C. flavigena, and Pseudomonas fluorescens subsp. cellulosa when they were cultured in a glucose containing medium, whilst gluconate was catabolised mainly via Entner-Doudoroff(ED) pathway, and to some extend through HMP shunt. Enzymes of ED pathway in the orgamisms were induced by gluconate. On the other hand Nocardia cellulans catabolised glucose and gluconate via EMP pathway and HMP shunt. The growth rate of N. Cellulans on gluconate were much slower than that on glucose.

본 연구에서는 글루콘산 및 그 유도체 생산에 관 한 기초자료를 얻기 위하여 일차적으로 글루콘산나 트륨의 생산조건에 대하여 실험하였다. 발효가 진행 됨에 따라 생성되는 글루콘산을 수산화나트륨을 이 용하여 중화시킴으로써 글루콘산나트륨으로 전환하였으며 이때 초기 당농도 및 pH의 영향을 정량적으 로 검토하여 생산성을 비교하였다. Aspergillus niger를 이용한 글루콘산나트륨 발효 에서 초기 농도 및 초기 pH가 발효 특성치에 미치 는 영향은 실험 결과를 종합하면 최대비생성속도는 초기 당농도 110g/$\ell$ 에서 $0.20hr^{-1}$로서 가장 높은 값을 나타내였으며 균체 빛 글루콘산나트륨 수율은 저농도 기질인 당놓도 26/$\ell$. 에서 0.24, 0.49로서 최대값을 나타내였고 잔당 농도는 5g/$\ell$. 미만이었다. 또한 총괄 글루콘산나트륨 생산성은 고농도 기질인 11Og/$\ell$에서 1.18g/$\ell$/hr로서 가장 높았다. 그리고 발효를 위한 최척 pH는 5.5이었다. 산업체 발효조 척용, 간헐 첨가 회분배양(intermittent feeding fed-batch)의 결과, 36시간 경과 후의 글루콘산나트륨 의 농도는 255g/l 이였으며 산업적 생산이 가능한 수준이었다.

본 연구에서는 체내 염증지표 변화를 모니터링 함으로써 새로운 천연추출물인 polycan 및 calcium gluconate 복합제제의 치주질환 개선 효과를 평가하고자 하였으며, 다음과 같은 결론을 얻었다. 1. 치은열구액 내 $IL-1{\beta}$는 대조군과 시험군 모두 시간에 따른 유의한 차이는 없었으나(p>0.05), 4주째 시험군이 대조군보다 낮았다(p<0.05). 2. 치은열구액 내 MMP-8과 $TNF-{\alpha}$는 4주째 시험군에서 초기에 비해 감소하였으며, 시험군이 대조군보다 낮았다. 3. 혈액 내 MMP-8은 4주째 시험군에서 유의하게 감소하였고(p<0.05), 대조군에 비해 통계적으로 유의하게 낮았다(p<0.05). 그러나 혈액 내 CRP는 유의한 변화가 관찰되지 않았다(p>0.05). 이상의 결과들을 종합해 보았을 때, polycan을 함유한 calcium gluconate 복합제 복용이 전신적인 염증성 생체지표에 영향을 미쳐 치은열구액 내의 염증매개물질들을 감소시킴으로써 치은건강에 긍정적인 효과를 나타내는 것으로 사료된다.

Hydrofluoric acid is a colorless gas or fuming liquid with a strong, irritating odor. Hydrofluoric acid burns are uncommon; however, if severe burn occur, they caused death from systemic effects, such as fatal cardiac arrthmia. We experienced two cases of hydrofluoric acid chemical burns on digits. These patients had typical clinical features of hydrofluoric acid chemical burns, such as pulsating pain at the burn site, as well as ischemic and necrotic skin changes. The hydrofluoric acid chemical burn was confirmed by a history of exposure. Subsequently, we made a calcium gluconate gel by mixing 20% calcium gluconate, an antagonist against hydrofluoric acid, with lubricant, and we injected 10% calcium gluconate subcutaneously when they complained of pain rated at higher than 5 on the pain scale. Simultaneously, we monitored the patients' electrocardiographs and checked their serum total calcium, ionized calcium, and magnesium levels serially. Clinical presentations and the emergency management of hydrofluoric acid chemical burns were reviewed along with the current literature. These patients were discharged without any significant complications.

The preventive effects of calcium gluconate injection and administration of anion feed on occurrence rates of the abomasal displacement and retained placenta were examined from 86 pregnant cows reared in Paju and Goyang cities in Gyunggi Province. The cows were divided into 3 groups: control (30 heads), experimental group I (28 heads) and experimental group II (28 heads), respectively. The control cows were not treated at all. The cows in experimental group I were intravenously injected with calcium gluconate(CMPK, Am. Tech. Canada, 10 g/head). The cows in experimental group II were given with the anion feed (Goyang TMR, Korea, 9 kg/head/day). The occurrence rates of the abomasal displacement in experimental groups were lower than that of control group and experimental group revealed the lowest prevalence rate, however, significance was not detected. The occurrence rate of retained placenta in experimental groups revealed lower prevalence than that of control group and experiment group II showed the lowest prevalence rate(p<0.01). Considering the above findings collectively, it was thought that administration of anion feeds was affective for prevention of the bovine retained placenta during drying milk period.

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.

The thermoacidophilic archaeon Thermoplasma acidophilum has long been known to utilize D-glucose via the non-phosphorylated Entner-Doudoroff (nED) pathway. We now report the identification of a gene encoding 2-keto-3-deoxy-D-gluconate (KDG) kinase. The discovery of this gene implies the presence of a glycolysis pathway, other than the nED pathway. It was found that Ta0122 in the T. acidophilum genome corresponded to KDG kinase. This enzyme shares no similarity with known KDG kinases, and belongs to a novel class of sugar kinases. Of the five sugars tested only KDG was utilized as a substrate.

Serum calcium level was decreased by submaxillary gland removal in rate. To investigate the mechanisms involved in the above change, the authors examined the effects of thyroxine, vitamin D₂, and calcium gluconate, which influence the metabolisms of calcium and submaxillary gland, on the serum calcium level of the intact and submaxillary gland removal rats. The results were as follows: 1) Serum calcium level decreased by submaxillary gland removal. 2) Vitamin D₂, increased the serum calcium level significantly. 3) Thyroxine falied to recover the decreased serum calcium level induced by submaxillary gland removal to the control level. 4) In submaxillary gland removal rats, vitamin D₂ failed to increase the serum calcium level. 5) In thyroxine administered rats for 55 days, of which submaxillary glands were removed, vitamin D₂ failed to increase the serum calcium level. 6) The serum calcium level in intact rats was increased slightly, but increased significantly in submaxillary gland removal rats shortly after intravenous injection of calcium gluconate.

I. Objectives Endodontic disease is caused primarily by bacteria that interact with periradicular host from the root canal system. Chlorhexidine gluconate is known to effective to eliminate Enterococcus faecalis which resists to other intracanal medicaments. The aim of this in vitro study was to develop a slowly releasing root canal disinfectant using using chlorhexidine gluconate and chitoic acid. II. Materials and Methods Three different group were prepared with different drug release mechanism. In group A, paper points as used core material were loaded with 20% chlorhexidine gluconate.(omitted)
