This study was carried out to evaluate the bioavailabilities and the digestibilities of oligopeptide chelated (peptide-Ca), anchovy bone (anchovy-Ca) and methionine hydroxyl analogue (MHA-Ca) calcium compared to those of calcium carbonate in rats. In exp1, CaCO3, were added to the basal diet at level of 0, 30 and 60% calcium of the AIN-93G diet. In test groups, peptide-Ca, anchovy-Ca and MHA-Ca, were added to the basal diet to provide calcium at the level of 40% of AIN-93G. In exp1, the bioavailabilities were evaluated from the regression equation of the ratios of theological/actual calcium intakes of each dietary treatment. In exp2, urine and feces was to evaluate the true- and apparent digestibility and apparent retention. In exp1, Ca-60% group had higher bone mineral density (BMD), bone mineral content (BMC) and bone breaking strength (BBS) than those of the other standard groups. The bone weight and ash content of the peptide-Ca and anchovy-Ca groups were significantly higher than those of the MHA-Ca. Bone calcium content were not significantly different from the test group. The bioavailability of the MHA-Ca group was shown higher BMD (71%), BS (38%) and BBS (27%) compared to another control group. But the regression coefficient for BMD, BS and BBS were lower compare with that of bone ash and BMC. In exp2, the true- and apparent digestibility of test groups were shown to over 90%. Peptide-Ca was not significantly different from other test group, but digestibility and retention were higher compare to other test groups. In conclusion, peptide-Ca, anchovy-Ca and MHA-Ca improved Ca bioavailability in the rats. The compounds were higher Ca digestibility compared with those of CaCO3. It is assumed that difference of digestibility for test groups may be correlated to the bioavailability of test groups in BMD, BMC, BS, BBS and bone ash respectively.

Hamartomata is the most common benign type of tumor, occuring in the lung. However, a cystic pulmonary hamartoma is extremely rare, and is difficult to diagnose due to its nonspecific nature. We report a case of cystic pulmonary hamartoma in which a popcorn-like calcification is clearly identified, thus enabling a confident diagnosis of the disease.

PURPOSE: We intended to find out clinical aspects and prognostic factors of near drowning children in this study. METHODS: We conducted a retrospective study on twenty eight near-drowning children, who were admitted to Gangneung Asan Hospital from March, 1996 to March, 2002. We investigated their clinical aspects and the differences between two groups, namely a good prognosis group and a poor prognosis group. Those in the good prognosis group had no neurologic impairments and were fully recovered while those in the poor prognosis group died or fell into vegetative states. RESULTS: Out of 28 patients, there were 18 males(64.3%) and 10 females(35.7%). Age distribution was < or =4 years in 10 cases, 5 to 8 years in 7 cases, 9 to 12 years in 8 cases, and 13 to 16 years in 3 cases. Seasonal distribution was summer in 18 cases, spring in 6 cases, autumn in 3 cases, and winter in 1 case. Submersion time was < or =5 minutes in 15 cases, 5 to 10 minutes in 7 cases, and unknown in 7 cases. Initial blood glucose level was 175.2+/-88.0 mg/dL and initial arterial blood pH was 7.24+/-0.21. Good prognosis group had 23 out of 28 cases(82.1%) while poor prognosis group had 5 out of 28 cases(17.9%) which included 4 deaths and 1 vegetative case. Between the two groups there were no significant differences in the distributions of sex, age, season, submersion place, transfer time to hospital and resuscitation time. However, submersion time, mechanical ventilation need, initial blood glucose level and initial arterial pH were significantly different between the two groups. CONCLUSION: We found out that poor prognosis is expected for near-drowning children of submersion time over 10 minutes, applied mechanical ventilation, high initial blood glucose level, and low initial arterial blood pH.

The aim of this study was to determine the effect of partial liquid ventilation (PLV) using a perfluorocarbon (PFC) on gas exchange and lung inflammatory response in a canine acute lung injury model. After inducing severe lung injury by oleic acid infusion, beagle dogs were randomized to receive either gas ventilation only (control group, n = 6) or PLV (PLV group, n = 7) by sequential instillation of 10 mL/kg of perfluorodecalin (PFC) at 30 min intervals till functional residual capacity was attained. Measurements were made every 30 min till 210 min. Then the lungs were removed and bronchoalveolar lavage (BAL) (35 mL/kg) was performed on the right lung and the left lung was submitted for histologic analysis. There was significant improvement in PaO2 and PaCO2 in the PLV group compared to the control group (p < 0.05) which was associated with a significant decrease in shunt (p < 0.05). There was no significant difference in parameters of lung mechanics and hemodynamics. There was a significant decrease in cell count and neutrophil percentage in BAL fluid and significantly less inflammation and exudate scores in histology in the PLV group (p < 0.05). We conclude that PLV with perfluorodecalin improves gas exchange and decreases inflammatory response in the acutely-injured lung.
