Sonographic measurements often give considerable diagnostic significance. However, large discrepancy betweenthe real anatomic sizes and sonographic measurements could cause an incorrect diagnosis. Authors carried out aseries of experiment using a phantom and two scanners and the results are as follows: 1. There is a littledifference in errors between two scanners, and the mesurement does not almost always correspond to the realdistance. 2. The rates of errors of the measurements are almost fixed regardless of the positions of thereflcetors. 3. There is no relationship between the transducer MHZ and error rate. 4. As the error is derived from the scanner electronics it is necessary to calibrate the scanner periodically, and if not calibrated one shouldconsider the error rate of the scanner in the anatomical measurement.

BACKGROUNDS: As life expectancy is increasing, it is necessary to evaluate the health and nutritional status in elderly, especially in tube-fed elderly patients whose malnutritional status is related to the increase in mortality. This study was conducted to improve the nutritional status in tube-fed elderly patients. METHODS: Effects of nutritional support on tube-fed elderly patients(> or =65years) for 8 weeks were investigated by biochemical assessment and weight. RESULTS: When comparing the biochemical changes of the control group(n=8) with those of the case group(n=8), it showed significant differences in total protein, serum albumin and TLC(p<0.05), not in serum transferrin, serum iron, hemoglobin, hematocrit and weight(p>0.05). CONCLUSION: This study suggests the in tube-fed elderly patients can be improved if nutritional support is properly administrated.

Genomic DNAs were extracted from cervical lavages of 49 patients with cervical cancer. Dot and Southern blot hybridization were performed using the P-labeled HFV DNA probes to find high risk HPV(type 16 and 18) infection that is known as the mast prevalent pathogenic factor in cervical cancer. Furthermore, genornic DNAs purified frnm cervical cancer tissues were studied in 8 out of 49 patients allowing us to convince the results from cervical lavages. The results were as follaws: 1. Dot blot analysis were used to examine the sensitivity and specificity of hybridization condition and HPV-DNA probes. Fasitive signals were obtained even at the level of 10pg for HPV DNA, but no signals could he detected at the level of as much as 400pg for salmon sperm DNA. 2. Dot blot of DNAs from cervircal lavages showed positive signals in 32.7%(16/49) with HPV type 16 probe and 20.4% (10/49)and one mixed infection was found. 3. When the DNAs from cervircal lavages of 49 patients were classified according to the clinical stage of cervical cancer, the infection rates of HPV type 16 and 18 were 50% (2/4) in CIN, 80% (4/5) in stage I, 64. 2% (9/14) in stage I b, 45% (9I20) in stage II and 16. 7% (1/6) in stage Ill and K respectively. The occurrenr,e of HPV type 16 and 18 seemed to be the highest in the cervical cancer stage 1 (68.4%(13/19). 4. Experiments perfornecl with genomic DNAs from 8 cancer tissues showed similar results compared to those of cervical lavages, but the intensity of positive signals was stronger. 5. Genomic DNAs from 5 patients(3 cases from cervical lavages and 2 cases from cervical cancer tissues) which showed strong positive signals to the dot blot analysis were further examined by Southern blot hybridixation using HFV type 16 DNA probe. When DNAs were digested with Pst 1 restriction enzyme, the five characteristic frgmenta of BFV type 16(2.8, l.9, l.6, 1.0 and 0.5 kb long in length) were recognized in ell 5 cases, These results may suggest a direet relatianship between HPV type 16 & 18 infectioas considered as the most effective methods for HPV detectioe and typing. Mo1ecular biclogieal studies in the reserarch of HPV are expected to reveal and help us understand the pathogenesis of cervical cancer.

PURPOSE: The purpose of this study was to evaluate alterations of regional cerebral blood flow (CBF) and cerebrovascular reserve (CVR), and correlation between these alternations and cognitive dysfunction in patients with chronic traumatic brain injury (TRI) and normal brain MRI findings. MATERIALS AND METHODS: Thirty TBI patients and 19 healthy volunteers underwen1 rest/acerazolamide brain SPECT using Tc-99m HMPAO. Korean-Wechsler Adult Intelligence scale test was also performed in the patient group. Statistical analysis was performed with statistical parametric mapping software (SPM97), RESULTS: CBF was diminished in the left hemisphere including Wernicke's area in all patients with lower verbal scale scores. In addition, a reduction in CBF in the right frontal, temporal and parietal cortices was related with depressed scores in information, digital span, arithmetic and similarities, In patients with lower performance scale scores. CBF was mainly diminished in the right hemisphere including superior temporal and supramarginal gyri, premotor, primary somatomotor and a port of prefrontal cortices, left frontal lobe and supramarginal gyrus. CVR was diminished in sixty-four Brodmann's areas compared to control. A reduction in CVR was demonstrated bilaterally in the frontal and temporal Iobes in patients with lower scores in both verbal and performance tests, and in addition, both inferior parietal and occipital lobes in information subset. CONCLUSION: Alterations of CBF and CVR were demonstrated in the symptomatic TBI patients with normal MRI finding. These alterations were correlated with the change of intelligence, of which the complex functions are subserved by multiple interconnected cortical structures.

The antihypertensive effects of once-daily 15mg dose of tripamide(Normonal(R)) were observed in 30 cases of essential hypertension, and the results were as follows; 1) Mean drop in systolic and diastolic pressure were 30 mmHg and 16 mmHg, respectively. 2) In 76.7% of cases, good or fair control of blood pressure was resulted. 3) There was no significant difference in heart rate before and after treatment. 4) There was no significant difference in serum K, BUN, and FBS before and after treatment. 5) There was no any other side effect which required discontinuing the treatment.

Among the many causes producing lower back pain herniated nucleus pulposus and bulging disk have occupiedlarge percentaages and uniformly showed defect on lateral aspect of contrast filled thecal sac. But it isessential to differentiate each conditions from the other because of their different treatment methods.differentiation at metrizamide myelography between a diffusely bullging disk(unlikely to cause nerve rootcompression) and a herniated disk is based on the curature, extent, and multipllicity of the extradural deformityof the anterolateral margin of the contrast filled sac and o hte presence of fusiform widening of the most distalpart of the affected nerve root. The deformities caused by a bullging disk are round, usually symmetrical(aothoughoccasionally more prominent on one side), do not extend above or below the disk space, and can show multiple levelinvolvement; the nerve root is uniform in caliber and normal in size(although some of severe bulging show fusiformwidening of the most distal part of the affected nerve root). The deformities caused by a herniated disk isangular and extends cephalad and/or caudal to the level of the disk space; the affected nerve root is usuallywidened in its most distal visible part. A consecutive series of 50 patients with low back pain and no pasthistory of back surgery who did metrizamide myelography underwent spine CT and /or laminectomy. Using the criterialisted above for differentiation of bulging from herniated disk on metrizamide myelography, the myelographicdiagnosis was correct in 32(22 patients) of 34(24 patients) (95%) surgically and/or computed tomographicallyconfirmed bulging disks and in all 26 (100%) surgically and/or computed tomographically confirmed herniated disks.
