A total of 42 cases undifferentiated large cell tumors were stained by immunoperoxidase techniques using antibodies against leukocyte common antigen (LCA) and epithelial membrane antigen (EMA). In 18 of the 21 cases studied, initially diagnosed as malignant lymphoma or Hodgkin's disease, reactivity with monoclonal anti-LCA (and noreactivity with monoclonal anti-EMA)indicated that the tumor was a lymphomas. The remaining 3 cases gave the reverse reaction pattern and therefore were classified as carcinoma. One out of 16 cases diagnosed as undifferentiated carcinoma proved to be a case of mialignant lymphoma in 5 patients in whom the original diagnosis was uncertain, a definite diagnosis was possible in all cases and 3 of these proved to be large cell lymphoma; the remainders, undifferentiated carcinoma. It is suggested that the staining of undifferentiated human neoplasms using combinations of antibodies reactive with epithelial and lymphoid cells may result in much greater diagnostic accuracy.

Mobius syndrome is generally considered to be a static disorder of congenital origin, and is manifested as unilateral or bilateral facial weakness and lateral gaze limitation. In most instances the syndrome occurs sporadically, but rarely familial cases have been reported. We report a family of three members with Mobius syndrome; a 7-year-old girl, a 6-year-old boy, and their 29-year-old mother. Each patient revealed facial diplegia, and unilateral or bilateral lateral rectus palsy. Brain MRI scans showed normal and there were no definite brainstem dysfunctions on electrophysiologic studies.

A clinical study was conducted to compare effectiveness of IV Globulin with that of steriod in childhood acute ITP. We carried out an experiment to 36 patients of acute ITP who recovered over 50.000/mm(3) of platelet count and not to recur in 6 months. Study group consist of 10 children who were treated with steriod only (Group A), 13 children who were treated with IV Globulin (0.4g/kg/d, 5 days, Group B), and 13 children combined with steroid (Group C) Study period was from January 1988 to December 1992, folllowing results were obtained. 1) There were no significant difference in sex ratio. age distribution, pretreatment hemoglobin level, platelet count and prolonged bleeding time among study groups. 2) The days which platelet count reached to 50.000/mm(3), 100,000/mm(3) were 3.7 days (Group A), 2.1 days (Group B), and 2.3 days (Group C), respectively (p<0.05). 3) Complete response rates within 4 weeks did not show significant difference (90% in Group A, 84.6% in Group B, 92.3% in Group C), the complete response rate within 1 week were significantly different among three group (44.4% in Group A, 90.9% in Group B, 83.3% in Group C)(p<0.05). In conclusion, it is more desirable for early treatment of a childhood ITP because IV Globulin is easy to normalize platelet count in a short time.

The effects of the topically applied antibiotics and Aprotinin were evaluated in the experimentally induced pseudomonas aeruginosa keratitis in rabbits. 40 albino rabbits were used for this study and were divided into 8 groups according to the treatment protocols as follows: Aprotinin 40u/ml, 1,OOOu/ml, 1O,000u/ml, antibiotics (Ciprofloxacin and Tobramycin), and antibiotics and Aprotinin combined-treated group. The drugs were instilled in the rabbits, cornea 6 times per day for 2 weeks. The clinical evaluation was performed using a hand-held slit lamp every day. For the histopathologic examination, we enucleated every samples at different time intervals and prepared specimens for light microscope. The results were Aprotinin-treated group showed progression of ulcer infiltrates regardless of its concentrations. There was a statistically significant difference between the antibiotics-treated group and the control group (p<0.05). However, the combination of Aprotinin and antibiotics were not able to gain statistical significance when compare with antibiotics alone (p>0.05). There was no clinical and histopathological differences in the rabbit cornea between ciprofloxacin and tobramycin treated group (p>0.05).

BACKGROUND: The effectiveness for vagal stimulation by ice water aplication to face during metronome-controlled respiration of 15 breaths/minute was examed. The importance of basal vagal tone and sympathovagal interaction in the individual variability of responsiveness to the vagal stimulation was investigated. METHOD: Fifty three 12~13 year old healthy volunteers were included. Vagal tone and sympathovagal interaction before and after application of ice water to the face were assessed by power spectral analysis of RR interval(heart rate) variability. RESULT: Basal heart rate, high frequency power, and low to high frequency power ratio were 81+/-13(58~110 beats/min), 791+/-1061(56~4161 msec2) and 1.08+/-1.22(0.04~4.85) during controlled respiration. After ice water application twenty three children developed 5 more nodal escape beats due to severe bradycardia. Minimum heart rate, high frequency power and low to high power ratio changed to 42+/-12(19~72/min), 1890+/-1882(221~7258msec2) and 0.64+/-0.43(0.12~1.46). The increased ratio of high frequency power, maximum heart rate decrement and its percent after stimulation were 5.44+/-5.62(0.63~24.26), 39+/-14(10~81/min) and 47+/-15(16~81%) respectively. The increased ratio of high frequency power was correlated with basal logarithmic high frequency power(r=-0.60, p=0.0004). Maximum heart rate decrement was correlated with basal logarithmic high frequency power(r=-0.41, p=0.0018) and low to high frequency power ratio(r=0.27, p=0.04). CONCLUSION: Application of ice water to the face during controlled respiration produces powerful vagal stimulation and bradycardia, however, there is a wide individual variability of responsiveness to it. The absolute basal vagal tone contribute to this individual variability.
