1.The Effect of Rauwolfia Serpentina on the Retinal Arterial Blood Pressure in Hypertensive Patients.
Journal of the Korean Ophthalmological Society 1959;2(1):45-49
The diastolic retinal arterial blood pressure was measured by Ophthalmodynamometer in 15 patients of essential hypertension before and after the administration of Raudixin three times a days. The follow up period was 4 to 70 days. The average fall of the systolic brachial blood pressure was 38.1 mmHg(from 174.6 to 136.5 mmHg) 19 days after the treatment, whereas the average fall of the diastolic brachial blood pressure was 19.6 mmHg (from 166.6 to 94.7 mmHg) 24 days after treatment. A positive correlation was demonstrated between the retinal and brachial diastolic blood pressures prior to the treatment. The diastolic brachial blood pressure showed its fall only 15 days after treatment, the average fall being 17.1 mmHg. During this period of time, the average fall of the diastolic retinal arterial pressure was 10.2 mmHg. In 6 cases, the retinal arterial pressure didn't fall back to the normal valures and in 5 cases of Keith-Wagener group II, the retinal arterial pressure remained unchanged in spite of the treatment. The percentage ratio of the retinal to the brachial diastolic blood pressure remained stationary in 3 cases, rose in 4 cases. The number of cases which show fall in this ratio gradually increased and about 80% of the cases demonstrated definite fall one month after treatment. The retinal arterial pressure remained stationary during 2 weeks after treatment in 60% of the cases. The significant lowering of the retinal arterial blood pressure was observed only one month after treatment in the majority of cases. The retinal arterial pressure fell below normal range in no case.

We present our technique for reconstruction of the posterior cruciate ligament (PCL) using the quadrupled hamstring tendons with EndoButton(Acufex Microsurgical, Mansfield, MA). This paper describes the surgical technique of the procedures and reports the preliminary results in 10 patients with a more than 12 months follow-up. There were 8 males and 2 females ranging in age from 17 to 37 years (average 25 years). The average time from injury to operation was 3 weeks (range; 2 weeks to 4 weeks). Of ten patients, 6 were classified as an isolated tear, 2 were associated with lateral collateral ligament tears. A torn meniscus was present in 2 cases. We used one-incision technique. The results of these PCL reconstructions with a minimum follow-up of 12 months are as follows. Patients were evaluated preand postoperatively using the Lysholm, and Hospital for Special Surgery Knee ligament rating scales. Average knee ligament evaluation scores were Lysholm preoperative 48, postoperative 87.6; and Hospital for Special Surgery preoperatively 33.5, postoperative 88.8. We chose the semitendinosus and gracilis tendons with EndoButton fixation for PCL reconstruction for specific reasons: (1) No injury to the extensor mechanism and (2) Easy passage of the graft through the tibial tunnel. (3) The problem about the screw and patellar bone-tendon-bone can be resolved. (4) It preserves intact meniscofemoral ligament, some intact fibers of PCL bundle. (5) When rupture of the PCL is associated with ACL tear, each ligament should be reconstructed. In such a case, we preserve patellar tendon for reconstruction of the ACL, The technique presented here is not applicable to all individuals requiring PCL reconstruction but does provide significant advantages to those patients for whom it is utilized. Although the clinical results are very promising at this length of follow up, long-term study is required to evaluate our PCL reconstruction procedure more precisely.

From 1993 to 1996, we have used a new modular shoulder prosthesis for the treatment of acute complex fracture of the proximal humerus. The purpose of this study is to evaluate function, pain relief, and patient satisfaction after moduiar hemiarthroplasty for proximal humerus fractures. The stucly included 12 patients (J2 shoulders) with an average age of 68.5 years (range, 60 to 84 years). According to the Neer classification system, there were 3 four-part fracture-dislocations, 5 four-part fractures, 3 three-part fractures, and #I head splitting fracture. 'fhe hemiarthroplasty was pert'ormed at an average of 4 days (range, 3 to 10 days) following injury. Deltopectoral approach was used in all patients, and the prostheses were implanted with cement in ten cases. Follow-up evaluation, at an average of 32 months post-surgery, included clinical and radio- graphic examination. Active forward elevation averaged 120 degrees; external rotation, 35 degrees; and internal rotation, to the first lumbar vertebra. All of patients, except two who had poor results, were graded as good or excellent according to UCLA shoulder rating scale. Complications consisted of one tuberosity dispiacement, one peri-operative death and one loosening of uncemented humeral prosthesis. We concluded that Modular hemiarthroplasty for acute complex fracture of the proximal humerus especially in severely osteoporotic elderly patients facilitated the restoration of humeral length, anatomic repositioning of tuberosities, and precise soft tissue balance, thereby allowing earliermotion to prevent the developement of painful shoulder stiffness.

A 53-year-old man developed some erythematous follicular macules accompanied with tingling sensation on both shoulders. Histologic finding showed a dense lymphocytic infiltrate around the infundibular portion of the follicle, where separation of the dermoepidermal junction was seen. The insect, obtained from the skin lesion, was identified as a larva of an Ap- hid

8.A study on cyclic AMP in alveolar bone treated by orthodontic forces.

Tooth movement by orthodontic force is based upon alveolar bone resorption at compression site and bone formation at tension site of tooth. The function of cyclic AMP is to participate not only in initial action of bone cells by mechanical forces but also in the continuous cellular response leading, to bone remodeling. This experiment was performed to clarify the role of cyclic AMP in bone remodeling by mechanical forces. The orthodontic forces of about 80 gm and 100 gm were applied to the right canines of maxillary and mandibular bone, respectively, in cats, treated for periods of time ranging from one hour to 28 days. Alveolar bones were obtained from compression and tension sites . surrounding tipping maxillary and mandibular canines as well as from contralateral control sites. The samples were extracted, boiled and homogenized, and the supernatants were assayed for cyclic AMP by a radioimmunoassay mothod. The results were as follows: 1. The orthodontic movement of canines was increased to the end of experimental period and the action of orthodontic forces on tooth movement was more effective in maxillary canine. 2. The cyclic AMP levels of alveolar bones in compression and tension sites initially decreased, then increased and remained elevated to the end of experiment. The differences of the cyclic AMP levels between treated sites and non-treated sites were gradually increased. 3. The cyclic AMP levels in treated sites of mandibular alveolar bone was higher than that of maxillary alveolar bone.
