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.

Solitary bone cyst are usually found in the juxta-epiphyseal region of metaphysis of long bones of children. They are rarely seen in non-tubular bones. The following case describes what we believe to be a solitary cyst of the capitate. Cyst was treated by radical curettage and packing with autogenous iliac bone. The most recent evaluation 7 months after surgery showed no discomfort.

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

BACKGROUND: Morphologic characteristics of the human embryonic and fetal periderm according to body region are not very clearly defined. OBJECTIVE: We have tried to Clarify the sequential development of periderm regionally. METHOD: Skin samples were obtained from 12 human embryos and fetuses ranging from 4 to 23 estimated gestational ages(EGA) and divided regionally into scalp, face, back. abdomen, thigh and sale. Specimens were observed by scainning with an electron microscope. RESULTS: Human embryonic end fetal periderm show distinct morphologic changes as follows along its own sequence of development flattened surface, elevated surface, fiormation of incomplete bleb. single bleb stage, multiple-complex bleb stage, formation of regressinjg bieb. Then towards the end of the second trimester, most of thieperidermal cells are completely regressed. Regional variation in peridermal development is not evide!nt during the embryonic period, but earlier development is apparent in the sole, face and scalp especially in the sole compared to other areas during the late first snd second trimester after EGA 9 weeks. CONCLUSION: The periderm, which can be seen only in embryonic and fetal epidermis, shows distinct sequential developmental changeis with regional variation.

The primitive erythroblasts in 21 cases of embryonic hearts from 4 to 9 weeks of gestation were studied with a light microscope. The nuclear diameter, the motosis, and the loss of nuclei of the primitive erythoblasts were analyzed quantitatively. The results obtained were as follows. 1. At 4 weeks of gestation, the blood cells consisted of proerythroblasts, along with basophilic polychromatophilic primitive erythroblasts. The nuclear diameter ranged from 3.20 µm to 9.20 µm, but the main range was from 4.20 µm to 6.00 µm. It was revealed that 9.50% had diameter of more than 6 µm. 2. At the fist half of the 7 week gestation when hepatic hemopoiesis developed, the blood cells consisted of basophilic, polychromatophilic, and eosinophilic erythroblasts. Cells of more than 6 µm in nuclear diameter were about 1.10% and thereafter gradually disappeared. The range of the nuclear diameters was from 2.60 µm to 7.00 µm, while a range from 3.40 µm to 5.20 µm wqs the main. The proportion of cells less than 4 µm in nuclear diameter was 39.58% and thereafter rapidly increased. 3. From the second half of 7 weeks to 9 weeks of gestation, the erythrocytes originating from hepatic hemopoiesis increasingly replaced the circulating primitive erythroblasts, which became mature during this time. The erythrocytes showed 72.88% at 9 weeks of gestation. The proportions of cells less than 4 µm in nuclear diameter in the first and second haIves of 8 weeks and 9 weeks were 52.73%, 80.02%, and 89.09%, which represented the rapid destruction of nuclei. 4. Mitosis in the primitive erythroblasts occurred principally up to the early 6th weeks, and very weakly at 8 weeks. 5. As the crown-rump length increased, the average nuclear diameter decreased very significantly (P<0.01, y=-0.2811X + 0.3171). The results suggest that distrilbution of the nuclear diameter, the maturity, the rate of nuclear loss, and the mitotic figure offer credible data for estimating embryonic age.

Authors analysed the corpus callosum of Korean(27 male & 14 female) anthrolopologically by the method of Kappers and Ban, and obtained the following results ; 1. The mean height of corpus callosum of the Korean male was about 25.9mm and that of the female was about 25.6mm. 2. The mean length of corpus callosum of the Korean male was about 69.1mm and that of the female was about 69.9mm. 3. According to the callosum horizontal index, the length of the cerebral hemisphere of the Korean male was about 2.22 times longer than that of the corpus callosum, and that of the female was about 2.27 times longer. 4. According to the callosum parietal index, the height of parietal lobe of the Korean male and female was about 2.8 times higher than that of corpus callosum. 5. The mean value of the callosum index of Korean was about 0.374, which was greater than that of the Japanese and Chinese, but lesser than that of Battak. 6. The most common type of corpus callosum of the Korean was the type III and VI, but the type I and X were not appeared. 7. According to the type distribution in relation to the callosum horizontal index, the type VI at callosum horizontal index 0.44 was the most common types.
