There is no sport in which the shoulder does not play an integral role. There are many patients with shoulder joint problems in volleyball, baseball, tennis and golf. In volleyball, a quick strong spike is necessary. Therefor, the treatment of shoulder injuries as well as the protection of the shoulder is a great concern of the player. The authors have done and analysis of the playing history and the clinical studies of the volleyball players who have been recorded as patients of the department of orthopedic surgery, Korea National Police hospital, from January 1977 to December 1980. Results of the study are as follows: l. Of the ages between 17 and 25, the average age was 19.9. 2. Out of 228 case studies 96 complained of shoulder pain or 42.1%. 3. The 84, or 87.6% of the players used the posterior angle spike. The anterior angle spikers and middle angle spikers were 6 players or 6.2% each. 4. Of 60 posterior angle spikers attempted to change spiking angle, 46 or 76% were able to alieviable the shoulder pain. 5. In the posterior angle spikers the lever arm is at its shortest extent so the cases of pain were analyzed as due to repeated impingement of supraspinatus tendon.

We performed Farnsworth-Munsell 100-hue test in pseudophakic eyes and phakic eyes to detect the abnormal color perception suggested in pseudophakic eyes compared with phakic eyes. But there were no significant differences in total error scores and mean error scores at four individual boxes between two groups. The results suggest that there were no differences in color perception between pseudophakic and phakic eyes by Farnsworth-Munsell 100-hue test.

In the present study, immunohistochemical detection of p53 oncoprotein was performed to determine whether the grade of differentiation and the histologic type of gastric adenocarcinoma, and the degree of atypia accompanied with adenoma can be related to p53 mutation. Paraffin sections of 22 gastric adenomas and 56 gastric adenocarcinomas were examined for the overexpression of p53 oncoprotein with the avidin-biotin peroxidase complex staining procedure. The obtained results were as follows; 1. All the 22 cases of adenomas and 16 cases of well differentated adenocarcinomas showed uniformly negative staining. 2.Seven of 18 cases of moderately differentiated adenocarcinomas(39%), and five of 30 cases of poorly differentiated adenocarcinomas(17%) exhibited p53 protein expression. 3. Three of 29 cases of diffuse type (10%) and 9 of 19 cases of intestinal type(47%) exhibited p53 protein expression. These results suggest that p53 mutation is important in carcinogenesis of the intestinal type of gastric adenocarcinoma, and there is no correlation between the differentiation of gastric adenocarcinoma and the degree of p53 oncoprotein overexpression.

BACKGROUND: Vascular lesions can be diagnosed by biopsy, simple x-ray, ultrasound, CT, MRI, venography and MR angiography. These diagnostic tools can identify the detailed structure and abnormalities in the peri-lesional area of vascular lesions. Color Doppler ultrasound (CDU) can demonstrate the hemodynamic features, distribution of veins and arteries, shunts and structures of vascular lesions. Authors have tried to categorize vascular lesions with CDU and also applied this to the selection of treatment methods. MATERIALS AND METHODS: Forty-seven vascular lesions were evaluated by means of CDU. All patients underwent a complete clinical evaluation as well as peak systolic velocity (PSV), peak diastolic velocity (PDV), resistive index (RI) of feeding arteries. In particular, we evaluated the hemodynamic features and structures of vascular lesions. We categorized the vascular lesions and then treated them with systemic steroid, compression, SPTL1 Dye laser, steroid intralesional injection and sclerotherapy. We evaluated the clinical improvement and objective effects of treatments by CDU. RESULTS: There were 37 hemangiomas and 10 vascular malformations. Vascular lesions were classified by the hemodynamic features and structures: category Ia (infantile hemangioma, regressed infantile hemangioma), Ib (RICH), Ic (deep hemangioma, mixed hemangioma), II (arteriovenous malformation), III (venous malformation, verrucous hemangioma). The clinical improvement after treatment was associated with the decrease of PSV and RI values. The clinical improvement above 50% resolution of the lesion showed 70.9% in category Ia, 50% in Ib, 66.6% in Ic, 83.3% in II and 50% in III. CONCLUSIONS: The analysis of hemodynamic feature and structures by CDU can be helpful in the study of vascular lesions. These processes suggest CDU be a useful modality in differential diagnosis of vascular lesions and a more advantageous tool in the decision of treatment policy than the conventional modalities. And it is also useful for the evaluation of treatment effects.
