1.Hair Zinc and Lead : Relationship to Nutrient Intake and Height and Body Weight in Korean Preschool Children.
The Korean Journal of Nutrition 2004;37(3):193-201
The objective was to evaluate the factors influencing on the growth of children aged 3 - 6 years by mini dietary assessment and anthropometric indices in 556 children and by analyzing mineral contents of hair from 273 children by inductively coupled plasma mass spectrometry (ICP-MS). The mean concentration of zinc (Zn) in hair was 68.9 +/- 31.1 ppm and the zinc level of 91% children was less than 60% of the reference value of 180 ppm. The mean content of lead (Pb) in hair was 1.76 +/- 1.20 ppm, but only 67% of 273 children was within the reference value of 2 ppm and the lead level of 33% of children was 2 - 4 times higher than the reference value. The level of Zn was negatively correlated with Pb content (r = -0.305, p < 0.01). Hair Zn content, regardless of age, was significantly positively correlated with height (r = 0.214) and body weight (r = 0.159). The height of 95.3% children was belonged to the normal range of 90 - 109.9% of standard value and the body weight of 49.8% children was in the range of 90 - 109.9% of standard value. However, 8.1% children was overweighted (110 - 119.9% of standard) and 9.4% children was obese (120 - 149.9% of standard) and 0.9% children was severe obese (> 150%) which resulted in total 10.3% obese. Contrary to our expectation 32.8% children was underweight (70 - 89.9% of standard) and 36% of the underweight children showed the low content of zinc (10 - 49 ppm) in hair. There was no significant correlation between dietary intake of Zn and hair Zn content. Hair Zn content was low even though children consumed greater than 75% of their requirement for zinc. Regardless of dietary intake of Zn, hair Zn level was rather negatively correlated to the content of Pb in hair. 38.8% children had an unbalanced diet which resulted in lower intake of calorie, Ca, Zn, vitamin B2 compared with those consuming variety of foods. Therefore, it would be needed that new approach for nutrition education to improve eating habit having the unbalanced diet in preschool children. It might be also suggested to develop new food products to complement the nutrients of Zn, Ca, Fe as snacks or dietary supplement for Korean preschool children.

Spondylometaphyseal dysplasia (SMD) is an extremely rare, which affects the spine and metaphy-ses of the tubular bones on terms of enchondrogenesis. Children who had Kozlowski dwarfism, type of SMD are not recognized until they reach school age since they have normal clinical feature, weight and size in early childhood. Authors experienced a typical case of Kozlowski type of SMD in a 10 years old male who had i) generalized platyspondyly with anterior tapering of vertebrae ii) generalized metaphyseal dysplasia iii) minimal changes in the carpal and tarsal bones. This case is to be reported with review of references.

PURPOSE: To illustrate frequently encountered anatomic variations on PNS computed tomography(CT) and to assess their clinical significance. MATERIALS AND METHODS: CT findings of 1523 patients, who underwent PNS CT with no history of sinus surgery, were reviewed, and prevalence of each anatomic variation and its relationship with mucociliary clearance pathway was evaluated. RESULTS: Two categories of anatomic variations were encountered. The first group included variations of the turbinates, such as concha bullosa(28.6% ), paradoxical middle turbinate(31.5%), of the uncinate process, such as medially bent or folded(36.3%), laterally bent(3.7%) or uncinate bulla(0.5%), of the ethmoidal sinus, such as Haller's ce11(28.2%), large agger nasi ce11(9.6%) or large ethmoidal bulla(23.5%) and nasal septal deviation(24. 1%), which might cause obstruction of mucociliary clearance pathway and thus give rise to secondary obstructive sinusitis. The second group included Onodi ce11(1.4%) and medial depression of the lamina papyracea (3.5%), which were not related with obstructive sinusitis. 87 cases of large agger nasi cell were associated with obstruction of nasofrontal recess. Large ethmoidal bulla(452 cases), Haller's ce11(245 cases) and true concha bullosa (25 cases) contributed to narrowing of the infundibulum. Medially bent uncinate process(220 cases), concha bullosa(157 cases), paradoxical middle turbinate(126 cases) and nasal septal deviation(93 cases) were observed in middle meatal obstruction and supreme concha (3 cases) accompanied sphenoethmoidal recess obstruction. CONCLUSION: Recognition of anatomic variations on PNS CT is important to build a treatment plan in patients with obstructive sinusitis as they may represent causes of the disease, and to avoid critical complications during functional endoscopic sinus surgery.

PURPOSE: To evaluate the incidence and CT findings of the medial depression and bony dehiscence of lamina papyracea as an anatomic variation. MATERIAL AND METHODS: 1472 PNS CTs of the patients with symptoms of chronic sinusitis were retrospectively evaluated. RESULTS: The total incidence of depressed lamina papyracea as an anatomic variation was 3.5%(52/1472) on PNS CT. There was a statistically significant correlation between the increasing age and the incidence of delamina papyracea. Depression of lamina papyracea anterior to the basal lamella were more common those of the posterior depression. Associated findings were herniation of adjacent fatty tissue in all cases and the roedial bowing and hypertrophied configuration of the medial rectus muscle without significant herniation in 19 cases(34%). CONCLUSION: Nontraumatic, asymptomatic depression with bony dehiscence of lamina papyracea as an anatomic variation is not uncommon with the incidence of 3.5%. Recognition of its existence and degree may helpful in avoiding various ocular complication during ethmoid surgery.

This study was performed to investigate the effect of endotoxin to the CCl4-induced liver injury. Twelve Sprague-Dawley rats were intraperitoneally injected 1.6 g/kg CCl4 as control group. Another 24 rats were orally administrated 300 mg/kg of neomycin at 16 and 3 hours prior to CCl4 injection as experimental group. Twelve among them were intraperitoneally infected 1.0 mg/kg of endotoxin(E-Coli, 0111:B4, No L-2630, lipopolysaccharide, Sigma, USA) and CCl4 simultaneously for offsetting neomycin effect. The rats were sacrificed at 1, 4, 10, and 24 hours after CCl4 injection. The liver tissues from all experimental groups were observed by light and electron microscopy. The results obtained were summarized as follows: In the CCl4 only group, the hepatocytes revealed sweling of ER and mitochondria with many lipid droplet in the cytoplasm. Focal cellular necrosis was seen at the later phase. The Kupffer cells were activated and showed many cytoplasmic processes, secondary lysosomes, and vaculoles. The endothelial cells were edematous. Several neutrophils, platelets, and microthrombi were scattered in the sinusoid. In the neomycin-CCl4-endotoxin administrated group, both hepatocytic destruction and intrasinusoidal microthrombi formation were more pronounced. In the neomycin pretreated group, the hepatocytes revealed mild cellular destruction without necrosis. There is no intrasinusoidal microthrombi. According to these results, it would be concluded that the small dosage of gastrointestinal tract-derived endotoxin affects to the liver injury caused by CCl4. The synergistic effects of CCl4 and gastrointestinal tract-derived endotoxin which can not be detoxified by damaged Kupffer cells, may be more important in the pathogenesis of CCl4-induced liver injury.

Renal dysplasia results from aberrant histogenesis in metanephric differentiation. It is characterized morphologically by abnormal organization and a persistence of primitive structures, such as cartilage, undifferentiated mesenchyme, and immature tubules. Six cases of renal dysplasia from five children and one adult are reviewed. Five patients were female and one patient was male. The chief complaint was urinary incontinence in four patients, dysuria in one patient, and the sixth patient suffered from vesicoureteral reflux. No evidence of family history of renal dysplasia in any patient was seen. According to Risdon's classification, three cases were hypoplastic dysplasia, one case was dysplasia in a duplex system, one case was dysplasia in a triplex system, and one case was dysplasia with vesicoureteral reflux. The ipsilateral ectopic ureteral orifice was identified in four patients, two of which drained into a Gartner's duct cyst, and the orifice was suggested in one patient. On histologic examination, all cases showed primitive ducts surrounded by concentrically arranged primitive mesenchyme. Nests of metaplastic cartilage were observed within the stroma in three of the six cases.
