The reference values of motor unit action potentials(MUAP) of first dorsal interosseous and tibialis anterior muscles were measured in 50 healthy subjects. The MUAPs were recorded with a concentric needle electrode and extracted with a decomposition method. Sixty six patients with neuropathy were also studied in the same way with a count of outliers and measurement of mean values. The mean values of amplitude, area, duration and thickness were 667.74+/-204.34 V, 992.26+/-253.18 Vms, 9.75+/-1.95 ms and 1.49+/-0.26 ms, respectively in the first dorsal interosseous muscles, and 612.88+/-140.13 V, 1172.84+/-199.21 Vms, 11.41+/-2.48 ms and 1.93+/-0.34 ms respectively in the tibialis anterior muscles. There was no significant difference in age and gender of normal subjects. The amplitude was the most sensitive parameter to detect abnormality in a count of outliers and measurement of mean values. The outliers count in duration showed a higher sensitivity than the measurement of mean values(p<0.05), but not in amplitude, area or thickness. Based on the results of this study, the count of outliers was more sensitive than the measurement of mean values in the diagnosis of patients with neuropathy. Further more, less numbers of MUAPs were needed for the evaluation of the outliers count. Through this method we could save the evaluation time and the patients felt more comfortable.

We have treated adult acute leukemia 64 patients between January 1990 and October 1991 at the Chungnam National University Hospital. They were examined for the impact of presenting WBC count on the initial course and from them we have chosen twenty patients whose leukocyte count is over one hundred thousands per cubic milimeter. We divided the twenty patients into 4 groups on the base of treatment modalities: conservative therapy only, chemotherapy only, cranial irradiation only, and chemotherapy with cranial irradiation. Early sudden death rate is lower in cranial irradiation with/without chemotherapy groups than the conservative only or chemotherapy only patients. Also the remission rate is high in cranial irradiation with chemotherapy patients. Therefore we suggest that the rapid intervention of cranial irradiation in adult acute leukemia could be helpful in reducing the early sudden death rate and perhaps in increasing the remission rate.

OBJECTIVES: Growth hormone is expected to delay the degenerative changes of the intervertebral disc and affect the initial recovery process of cartilage injury, but these effects are still open to disputes. METHODS: This researcher injected growth hormone to the intervertebral disc and subcutaneous tissue of rabbits whose degenerative change were induced artificially, and evaluated the treatment effects of growth hormone through a comparison between the injected and control groups of rabbits. The intervertebral discs between the 3th and 4th vertebrae were extracted 4 weeks after the administration of growth hormone and then histologically graded in a quantitative method. Changes in the height of the intervertebral discs were measured after the induction of degenerative changes. After four weeks of the treatment, then, the height changes were measured. RESULTS: In the subcutaneous-growth hormone injected group, any consistent, sequential, and progressive degeneration of the annular fibrosus was not observed through histopathological studies. The disc height also sequentially did not decrease from that at the time of the injury set in this study. CONCLUSIONS: Considering the histopathological findings of the study, the researcher suggests that subcutaneous injection of growth hormone will be a therapeutic model of disc degeneration. But further biochemical or electromicroscopic studies are necessary to clarify the mechanism of delay degenerative disc changes by growth hormone.

Dieulafoys lesion consists of abnormally large gastric submucosal artery which ruptures into the stomach causing massive or recurrent intragikstric bleeding. The lesion is very small and easily overlooked even at laparatomy and aan only be correctly diagnosed by endoscopy or arteriography if the patient is actively bleeding. Three patients who were admitted with bleeding of upper gastrointestinal tract and eventually diagnosed as having Dieulafoys lesions were analysed. All were men with age range of 44 to 55 years. All patient were asymptomatic before presenting with hematemesis. Two of the three patients had had history of upper Gl bleeding. One patient used analgesics daily for ureteral colic and two patient drank alcohol excessively. Gastroscopy was performed during the bleeding episode in all three patients. Dieulafoy's lesion was seen in all three cases and in the second case, there was concomittent diffuse petechia in the whole stomach. The lesion was situated on the posterior wall of upper body in one, on anterior wall of upper body in another, lesser curvature side of gastric fundus in the other case. All three patient underwent laparotomy for persistent bleeding and the lesion was suture ligated only in two patients while in one patient vagotomy and pyloroplasty was added. Resection biopsy was performed in two cases and both revealed only normal gastric mucosa. All patients discharged after complete recover.

OBJECTIVE: The purpose of this study was to determine differential findings between Type I degenerative endplate changes and diskitis on MR images. MATERIALS AND METHODS: MR images(T1, T2 weighted or Gradient echo) of L-spine in twelve patients with a Type I degenerative endplate change and nine patients with diskitis were reviewed for the morphologic and signal intensity changes of intervertebral disc, vertebral endplate and vertebral body. RESULTS: involvement of the marrow of one side of intervertebral disk was noted in 33%(4/12) of Type I endplate changes, and 11%(1/9) of diskitis. Decreased signal intensity of intervertebral disc was seen in 92% (11/12) of Type I endplate changes, and 11%(1/9) of diskitis on T2 weighted or Gradient echo image. Loss of intranuclear cleft signal was noted in 17%(2/12) of Type I endplate changes, and 78%(7/9) of diskitis. Even disc space narrowing was seen in all cases of Type I endplate changes, but uneven narrowing was seen in 44%(4/9) of diskitis. Only partial cortical disruption was noted in 42%(5/12) of Type I endplate changes, while partial or total cortical disruption was noted in 89%(8/9) of diskitis. The extent of marrow involvement more than 2/3 was noted in 8%(1/12) of Type I endplate changes, but 56%(5/9) of diskitis. The margin of signal intensity change was well defined in 33%(4/12) of Type I endplate changes, but that of diskitis was ill defined in all cases(9/9). Gadolinium enhancement was homogeneous in all cases(5/5) of Type I endplate changes, and 63%(5/8) of diskiris. CONCLUSION: We conclude that involvement of one side of endplate, decreased signal intensity of intervertebral disc on T2 weighted or gradient echo image, even narrowing of disc space, lesser extent of marrow involvement, well defined margin and homogeneous enhancement pattern are the findings of Type I degenerative endplate changes on MR images.

In a jaundiced patient, it is important to ascertain as early as possible whether the bile duct is dilated. Ultrasonography, computed tomography & conventional cholangiography are widely accepted methods of determining the size of the extrahepatic bile ducts. But there is a considerable discrepancy among the size of the bile duct as measured from them. So the author analyzed and compared the respective diameters of the bile ducts in Korean normal adults as measured from cadaver, IV cholangiography, ultrasoud and computed tomography. The materials were 45 cases of cadaver, 38 cases of IV cholangiography, 100 cases of ultrasonography & 55 cases of computed tomography. The results were as follows ; 1. The diameters of the bile ducts were 7.58±2.26mm at CHD & 8.04±2.42mm at CBD from cadaver ; 5.38±1.90mm at CHD & 6.58±2.37mm at CBD from IV cholanglography ; 3.24±1.13mm at CHD & 4.71±1.48mm at CBD from ultrasonography ; and 4.56±1.51mm at CHD & 5.87±1.68mm at CBD from computed tomography. 2. The diameter of the bile duct was greatest in cadaver, and then reduced in IV cholangiography, computed tomography and ultrasonography in this orde.r 3. There were no size discrepancy between the diameter of the common hepatic duct and that of the common bile duct. 4. There were no discrepanry of the diameter of the bile duct by sex.
