The papillary eccrine adenoma is a rare benign sweat gland neoplasm charscterized by potentislly locally aggressive clinical course. We report herein a case of papillsry eccrine adenoma in a 28-year-old female who presented single intradermal tumor on the right postauricular ares. Histopathological findings showed dilated ducts containing eosinophilic or keratinous materials and intraluminal papillary rowths.

The present study was performed in order to test the effects of diphenylhydantoin (DPH) and two central nervous system (CNS) stimulants, intermittent light stimulation(ILS) and pentylenetetrazol (Metrazol) on body temperature (Tb) during cold exposure in the bat DHP delayed the onset of entry into hibernation in both the oriental discoloured bats and the little brown bats and formed long and prominent plateaus that were not found in the normal and the controls. The responses of body temperature to the ILS were sensitive and the body temperature fell dramatically in the big brown bats. Metrazol effects on body temperature were obvious but; seemed dose-dependent. The experimental results further support the hypothesis that hibernation is an epileptic fit as suggested by serveral researchers.

Radiological demonstration of lymph vessels and lymph nodes may be achieved only by direct lymphography, whichis perfomred by injecting contrast material directly into the lymph vessels. lymph nodes, or occasionally intolymph cysts. Clinical lymphography is performed essentially according to the direct technique of Kinmonth(1952 &1954). Lymphography has become a routine procedure in patients with carcinoma of the uterine cervix. Thoroughassessment of the extent of carcinoma of the uterine cervix is necessary to the intellignet management of anypatient with uterine carcinoma. This presentation is to outline the technique of lymphangio-adenography(lymphography), lymphographic finding and diagnostic criteria of the cervical carcinoma, and evaluation of theaccuracy of lymphographic diagnosis in cervical carcinoma. A retrospective reivew of the lymphograms of 145patients with carcinoma of the uterine cercix was undertaken. All lymphograms were performed at Kang Nam St.Mary's and St. Mary's Hospitals, Catholic Medical College form 1975 to 1982. Of thse patients 87 were got radicalhysterectomy and lymphographic diagnosis was compared with tissue pathology of the nodes removed, and determinedthe diagnostic accuracy of lymphography. Lymphography can make a significant contribution in the pretreatmentassessment of patients with carcinoma of the uterine cervix. Strict adherence to rigid criteria will yieldexcellent pathologic correlation in the event of a positive radiographic diagnosis of metastatic carcinoma. Once apositive diagnosis is made, it should influence the management of the cancer patients. The results were as follow;1. The accuracy of lymphography in diagnosing lymph node metastasis of carcinoma of the uterine cervix was 85.1%,82.4% in sensitivity and 86.8% in specificity. 2. Metastic lymph nodes were moderately to markedly enlarged andirregular in shape and shown motheaten marginal filling defects in 92.7%. Theses ranged from 3mm to 20mm in thegreatest diameter. 3. Metastatic lymph nodes showed a tendency to get increased in size, inproportion to the sizeof marginal filling defect. 4. The size of filling defect of metastatic lymph nodes was not correlated to theclinical stage of carcinoma of the uterine cervix. 5. Lymph node metastasis was confirmed in 6 patients of 10patients who were got lymphography in 2 to 5 years after radical hysterectomy. 6. Many collateral lymphatics andlymphatic cysts were found out in the lymphography after radical hysterectomy in carcioma of the uterine cerix.

To obtain wider versatility and greater reach in microsurgical lumbar discectomy, modified procedure has been performed on 263 patients in 1979-1983. It consisted of a smaller midline incision, removal of lateral half of the spinous process, partial but sufficient microdrilling of the lamina, use of a modified slender Taylor retractor, flavotomy, preservation of epidural adipose-areolar tissue etc. Particularly a slender Taylor-Chung retractor offered yielding surgical opening and therefore secured free of pituitary forceps to every direction. The microsurgical results including 72 bisegmental and 8 trisegmental discectomies were compared with those of standard operations of same number performed by same surgeon in 1972-1979, for the good contrast. Mean blood loss per operation was 94 ml with the standard discectomy and 46 ml with microsurgery. Dural tear occured in 17 cases undergoing standard operation and in 3 undergoing microsugery. The mean time until return to duty was 8.6 weeks with standard, compared with 4.2 weeks. In the microsurgical group, 3 patients had postoperative discitis while 2 had in the standard. In this series, the results of microsurgery surpasses the standard in the convalescent phase. Major advantages of this modified microsurgical technique were its ability to secure the greater reach to remove disc material as much as possible and to preserve the integrity of normal tissue better.

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.

Authors report the radiologic findings of two cases of multiple bile-duct hamartoma in the liver. Ultrasonography and computed tomography of the liver were performed in two female patients. In one patient, ERCP was performed. Ultrasonography and computed tomography showed scattered multiple hypoechoic and low attenuated lesions, measuring up to 2cm in both lobe and ERCP showed communication of these lesions with the biliary system. Multiple bile-duct hamartoma should be included in the differential diagnosis of multiple small cystic lesions in the liver.

Recently, many authors have reported about the relationship of the volumes of hemorrhage in the brain parenchyma, hemorrhagic sites, optimal operation time, and the effects of mannitol and steroid on control of ICP to clinical manifestations. Many attempts to measure ICP in hydrocephalus, brain tumor, and head injury have been reported. But the measurements of intracranial pressure in spontaneous intracerebral hemorrhage are rare. Intracranial pressure was monitored prospectively in 30 patients who had stereotaxic surgery for spontaneous intracerebral hemorrhage. The results are as follows. 1. Intracranial pressure was increased in high PaCO₂. 2. There were no correlation in ICP, rebleeding and ADL ad discharge (P>0.05). 3. ICP was the most high level in 72 hours after operation. 4. There was 63.2% decrease in ICP after irrigation with 6000 IU urokinase in the site of hemorrhage. 5. There was no correlation between the numbers of natural drainage and ADL at discharge (P>0.05). 6. The higher the initial GCS, the higher the postoperative GCS.
