The early ultrastructural changes of basement membrane thickening and degeneration of the pericyte were noted in retinal capillaries in diabetic patients. However no early ultrastructural changes were reported in diabetic iris capillary. The authors studied the ultrastructural features of basement membrane of iris capillaries which were obtained during cataract surgery in five diabetic patients and compared with those obtained in five nondiabetic patients. The endothelium basal lamina, pericyte basal lamina and membrane-like pericyte matrix in didabetic iris capillaries were thicker than those in nondiabetic Iris capillaries. The thickening of pericyte basal lamina is more prominant than the endothelium basal lamina in diabetes. The duration of diabetes had no relationship to endothelium basal lamina but, showed statistically significant relationship to thickness of pericyte bascal lamina and pericyte matrix.

Lymphangiectasia(acquired lymphangioma) is characterized clinically by the presence of a circumscribed eruption of thin-walled, translucent vesicles which closely resemble frog spawn in appearance. This rare disorder may arise as a result of acquired lymphatic obstruction secondary to surgery, irradiation, chronic recurrent infection, chronic scarring, or trauma. Herein, we report a case of atypical lymphangiectasia at the site of an abdominal scar in a 70-year-old female. She developed a dark red-colored, pedunculated papule, 2 years after a total abdominal hysterectomy and post-operative irradiation for carcinoma of the uterine cervix. Histopatholgical findings showed multiple irregularly shaped cystic dilatated cells lined by a single layer of endothelium in the dermis. Immunohistochemical staining with factor VIII-related antigen showed negative results. A lymphangiogram showed signs of acquired lymphatic obstruction.

BACKGROUND: Local anesthetics have been widely used to control postoperative pain and chronic pain. However, their usage in controlling long-lasting pain has been limited due to a relatively short duration of action. Many attempts have been made to develop a controlled release drug delivery system to provide long-lasting anesthesia. The goal of this study was to evaluate the histocompatibility and effectiveness of a new injectable lipid gel type drug delivery system (PHW, egg phosphatidylcholine/hyaluronic acid/water) using bupivacaine. METHODS: Eighty-four male Sprague-Dawley rats were divided into 3 groups; 44 in the bupivacaine group, 20 in the PHW-bupivacaine (PHW-B) group, and 20 in the PHW group; and each drug mixture was injected in a 0.1 ml solution near the sciatic notch. Motor block was assessed by direct observation of motor skills to splay toes. Sensory block was assessed by measuring withdrawal response latencies to radiant heat using an analgesiameter. Gross and microscopic examinations on the sciatic nerve and surrounding muscle were performed for 3weeks after the injection. RESULTS: Nerve block was significantly prolonged in the PHW-B group (190.0 +/- 42.8 min) compared to the plain bupivacaine group (99.0 +/- 30.5 min). There was no sign of nerve block in the PHW group. We observed moderate perimuscular inflammation in the PHW and PHW-B groups for the first 3 days. After 3 days, we did not observe inflammation of muscles and there was no sign of perineural inflammation. CONCLUSIONS: In conclusion, the histocompatibility of a bupivacaine incorporated PHW drug delivery system was satisfactory and the controlled releasing property of this drug delivery system was evaluated as effective.

Three parameters (lumbar lordosis, lumbosacral and sacral inclination angle) were measured on 512 normal plain lateral radiographs of lumbosacral spine and the patterns of change during aging were studied. The following results were obtained. 1. The lumbar lordosis angle showed a tendency to increase with age. But a brief decrease was observed after the 6th decade in both sexes, between the 2(nd) and 3(rd) decades in males, and between the 3(rd) and 4(th) decades in females. The lumbar spines of females were generally more lordotic than those of males. 2. The lumbosacral angle appeared to increase with age. The angle in males showed a decline between the 2nd and 4th decades while the angle in females decreased after the 6th decade. Males usually had greater angles than females. 3. The sacral inclination angle continued to increase until the 6th decade, after which a decrease was noted. The angle in females was generally greater than that in males. These results showed that all three angles varied with age, and the pattern of change differed between male and female.

The goal of cleft lip surgery is to reconstruct normal shape of the lip. To acomplish this goal, various operative method were contrived and concept of the method decided the shape of reconstructed lips. According to the operative result, some operative methods were disappeared or have been developed with a little modifiation. Traditional Millard's rotation-advancement method for unilateral cleft lip patients is largely accepted and developed as proper method for acquiring these functional and anatomic purposes. As a trial for this development, Mulliken add some modifications. He uses exaggerated high rotation incision and it lengthens into midcolumella without backcut. Also he dosen't steal from alar base or lateral lip for vertical height. C-flap is used to lengthen the affected columella and upper lip. The isolated orbicularis oris muscle is coaptated each other for more functional result. With supraperichondral dissection of alar cartilage and transpositioning of caudal septum, he performs synchronous repair of cleft lips, nose and sometimes alveolus. It is still debated when is most suitable age for surgical correction of nasal deformity of cleft lip patients. Done at the time of primary lip repair, there are both some apprehension and inducement. The former are based on technical difficulties due to shortage and fragility of neonatal tissue and possibility of progressive deformities with growing because of iatrogenic injuries to the alar cartilages. But te latter is rationalized because early reposition of deformed nasal cartilage in proper position would induce more natural growth of nasal structures. Some long-term follow up reports reveal the early operation innocent of any growth deterioration. Mulliken treats his cleft lip patient for separated lip and nasal deformities with single operation, and does gingiovoperiosteal alveoloplasty at the same time if necessary. He uses Latham appliance from 4 to 6 week after birth in case of severly collapsed lateral alveolar segment or wide alvolar gap, and perform the definitive opertation at the age of 4 to 6 months. I use lip adhension method to correct more than 10 mm alveolar gap without severe collapse of lateral alveolar segment, but if lateral segment was severely collapsed and away from alvolar arch, I apply the Latham appliance somewhat modificate from original type, which has a metal ring fastened at the front limb of appliance for rubber banding to coaptate easily. I have experienced repair of cleft lip by Mulliken's concept with some modification of my own to 44 cases of unilateral cleft lip patients and conclude that it was very flexible method. Doing with synchonous repair of cleft lip nose, we could get harmonious lip and nose with symmetric nostril sill, cupid's bow and red line. Columella was lengthened primarily. Normal growth of nose was anticipated by anatomic repositioning of alar septal cartilage.
