To determine the impact of intake large amount whole cow's milk (WCM) on iron status during early childhood (18~36 months), selected indices of complete blood count(CBC) and iron status were compared between the WCM large amount intake group (n=20)and small amount intake group (n=20). WCM large amount intake children's mean hemoglobin and mean hematocrit were 9.6+/-1.7 g/dL and 30.8+/-4.5% respectively. These range of peripheral blood with other indices of CBC disclosed the hypochromic microcytic anemia. WCM large amount intake children's some indices of CBC-hemoglobin, hematocrit, MCV, MCH-were significantly lower than those of small amount intake children (P<0.01). WCM large amount intake children had significantly lower mean iron, transferrin saturation and ferritin (P<0.01) and greater mean total iron binding capacity (P<0.05) than did small amount intake children. It is concluded that intake large amount of WCM for long duration impacts on the iron status of 18~36 months old children disadvantageously. It should be avoided for the protection of irreversible recognitive impairment and behavioral change.

The bone mineral density (BMD) has been measured for evaluation of the osteoporosis. Of the various methods of measuring the BMD, dual energy X-ray absorptiometry (DEXA) has been known to be an accurate, objective, and easily reproducible method. The authors measured BMD in patients with intertrochanteric fracture of the femur for comparison with results in the normal control. The BMD was measured in thirty-two patients with intertrochanteric fracture by dual energy X-ray absorptiometry from March 1993 to March 1995. And the relationship between the severity of osteoporosis and intertrochanteric fracture of the femur was studied. The comparison of BMD between fracture patients and normal control was done in the population below 79 years old of age (23 fracture patients and 90 normal controls). The average BMD in the intertrochanteric fracture group was 0.558g/cm2 in the neck, 0.425g/cm2 in Ward's triangle and 0.568g/cm2 in the trochanter, while in the normal control group it was 0.870g/cm2 in the neck, 0.681g/cm2 in Ward s triangle and 0.772g/cm2 in the trochanter. In comparison with the normal control group, the BMD in fracture group was about 79% of the normal control group. The BMD in the proximal femur was decreased by about 14% with the age increasing decennially after 50 years. The BMD at Ward s triangle and trochanter was much lower in type III and IV of Tronzo classification than in type I and II .The BMD did not show significant correlation with the height and weight of the patients.

Cysticercosis which very rarly involves spinal canal, may show symptoms similar to herniated nucleus pulposus and cord tumor, and even myelogram may not be helpful for the accurate diagnosis. In this paper, a case in which free floating larvae of taenia solium mimicking intradural tumor by myelogram and clinical symptoms were presented. The present authors feel that cysitcercosis has to be considered as a cause when there is central filling defect of contrast media in myelogram.

Insulinoma is a rare tumor, occurring more often in women and in the older age range. Eighty percent of patients have a single benign tumor, usually 2 cm in diameter, located with about equal frequency in body, head or tail of pancreas and amenable to surgical cure. About 10% have multiple tumors. The remaining 10% of patients have metastatic malignant insulinoma. The symptom of insulinoma is characterized by the periodic attack of hypoglycemia of blood sugar level below 50mg%, by fasting or exertion, and rapid relief of symptom by oral or intravenous administration of glucose. Symptom often lead to misdiagnosis as a neurologic or psychiatric disorder. A case described by authors was 44-year old female with the chief complaints of the loss of consciousness, epileptic seizure although she has been treated by anticonvulsants. Serum blood sugar and insulin level during fasting suggested insulinoma but abdominal computed tomography shows no definitive mass in pancreas. Celiac angiography revealed insulinoma. She transferred to the department of General Surgery and was performed enucleation. Microscopic findings shows the islet cell tumor of pancreas. A brief review of the literature was made.

OBJECTIVE: The purpose of this study was to evaluated the effects of alcohol on neurocognitive function, psychomotor performance and subjective response in healthy Korean adults with different ALDH2 genotypes. METHOD: A total of 24 males, half with active ALDH2*1/2*1 and the other with inactive ALDH2*1/2*1, was selected through genotyping using restriction fragment length polymorphism. In a double-blind, placebo-controlled cross-over design, each subject consumed 0.5g/kg dose of alcohol, given as a mixture of 40% vodka and orange juice, and placebo(orange juice) on two separate occasions on an average of weekly intervals. The blood alcohol concentrations(BACs) were measured using a breath analyzer at baseline and at 30, 60 minutes after drinking. P300s were measured at baseline and at 30 minutes after alcohol and placebo intake. Vital signs and psychomotor performance[Critical Flicker Fusion Threshold(CFFT), Choice Reaction Time(CRT), Digit Symbol Substitution(DSS)] were measured at baseline and at 60 minutes after alcohol and placebo intake. Subjective responses were measured at the end of the study. The statistical analysis focused on whether there were any differences between groups with different ALDH2 genotypes. RESULTS: The major results are as follows. 1) BACs in inactive group were overall equivalent to those in the active group. Only in terms of time, BACs were significantly higher overall at 30 minutes than at 60 minutes after alcohol intake. 2) Pulse rates were significantly increased after alcohol intake compared with placebo, and the increase was greater in the inactive than in the active group. 3) P300 latencies in leads Fz(frontal), Cz(cental) and Pz(parietal) were significantly increased after alcohol intake compared to placebo, and the increase was greater in the inactive than in the active group. P300 amplitudes in leads Cz and Pz were significantly decreased overall after alcohol intake compared to placebo. 4) Compared with placebo, alcohol produced significant effect on the psychomotor performance : impairment in the inactive group, improvement in the active group. 5) Compared with placebo, alcohol significantly induced a negative or an intense effect on the subjective responses in the inactive group, but little negative and even a somewhat positive effect in the active group. CONCLUSIONS: These results suggest that ALDH isozyme variance might be an important factor to determine the effects of acute dose of alcohol on the various psychobehavioural functions and also to determine the alcohol use pattern and to predict the future development of alcohol overuse and/or abuse.

BACKGROUND: The determination of serotype of enteroviruses is useful for the discrimination between sporadic and epidemic infections. The conventional serotyping method is time-consuming and labor-intensive. Recently, molecular method was introduced for the serotyping of enteroviruses. The aim of this study was to establish a method to isolate and analyze enteroviruses from various specimens utilizing molecular biological techniques and to determine which strains were phylogenetically related to clinical samples. METHODS: Clinical samples in this study included 164 cerebrospinal fluid (CSF), 136 stool, 15 sera, 6 throat swab, 5 urine, and 4 sputa, which were obtained from hospitalized patients, primarily infants or children presenting symptoms of aseptic meningitis in 1998. RD cells were used for enterovirus isolation. RT-PCR was performed with RD cell lysate showing CPE. The primers 011 and 012 were used for the VP1 region, and the primers EN1 and EN2 for 5'-UTR. The nucleotide sequences of VP1 region were determined and analyzed with BLAST program. RESULTS: Among 333 samples, only 23 samples produced CPE: 17 samples at first and six samples at the second blind passage. Fifteen isolates were related to coxsackievirus B2 two to echovirus 4, three to echovirus 6, and three to echovirus 18. All 23 viral isolates displayed a nucleotide sequence identity of 80-95%, compared with the reference serotypes. However, the identity was increased up to 93-100% when the VP1 region was translated into amino acids CONCLUSIONS: Since CB2 type was 55% among enteroviral isolates, the CB2 was determined as the major causative serotype of enteroviral meningitis in 1998. CB2 type was emerged between June and July, EC4 and EC6 was limited to July, and EC18 was in August.
