PURPOSE: To investigate the neuroprotective effect of growth hormone(GH) on neuronal cell necrosis and apoptosis at 1 week and 3 weeks after hypoxic ischemic brain injury. METHODS: Sprague-Dawley rats, seven-day-old, were used. Rats were anesthetized with ether less than 5 minutes. The right carotid artery was cut between double ligation. And then, rats were allowed to recover for 30 minutes followed by exposure to 8% oxygen at 37 degrees C for 2 hours for hypoxic ischemic insult. The study group was divided into 2 groups, control group(N=3) and GH treated group(N=3). GH treated group received intraperitoneal injection of GH 1 IU 2 hours after hypoxic ischemic insult following daily adminstration as same dose for 5 days. Rats were decapitated at 1 week and 3 weeks after hypoxic ischemic brain injury. After then, right hippocampal CA1 and CA3 neurons of rat brains were examined. RESULTS: Necrosis was significantly less in GH treated group than control group, and was more prominent at 3 weeks in both groups. The apoptosis was not found in GH treated and control group. CONCLUSION: GH has a neuroprotective effect on neuronal cell deaths(especially necrosis) from 1 week to 3 week after hypoxic ischemic insult in neonatal rat.

Malignant lymphoma of the bone is a rare, but involves the shaft or metaphysis of the bone, producing destruction, frequently pelvis, spine, skull and femur. Most of the patients are over thirty years old and equal sex distribution. The authors experienced one case of lymphoma involving the left ilium.

We analyzed 41 cases of burst fractures on the thoracolumbar junction which were operated with Kaneda and Cotrel-Dubousset implant at Chosun University Hospital between 1989 and 1993. The purpose of this study was to evaluate the radiologic sign, the amount of reduction, complications, and functional results. The results were as follows: 1. According to McGrorys Criteria to evaluate the posterior superior vertebral body angle of burst fractures, 33 out of 41 cases(80.5%) were positive and the average angle degree was 107.6°. 2. The average postoperative kyphotic correction was 15.4° in the Kaneda group and 13.8° in the C-D group. The average loss of correction at follow-up examination was 5° in the Kaneda group and 4.8° in the C-D group. 3. Indirect reduction was achieved in 10 cases(50%) and we obtained a good indirect reduction even though canal compromise was over 50%. 4. The pain at operative site was much more severe in the Kaneda group(6 cases) than in the C-D group(2 cases) and both groups experienced 2 cases each of implant failure. 5. According to Denis' pain and work scale, 28 cases(63.8%) had good and excellent, 8 cases had fair and 5 cases had poor results. In summary we recommend doing 1) a posterior instrumentation first for stability and indirect reduction, if it is not a severe neurologic symptom and 2) anterior decompression if it is a severe or progressive neurologic symptom.

OBJECTIVE: This study was to investigate the clinical efficiency of clomiphene citrate/GnRH antagonist protocol comparing with the clomiphene citrate only protocol in infertile women with normal ovulatory cycles. METHOD: Among 116 patients, 43 were received assisted reproductive technologies using natural ovulatory cycle, 38 and 35 were received clomiphene citrate only protocol and clomiphene citrate/GnRH antagonist combined protocol, respectively, and the clinical results were compared and analyzed. RESULTS: In each group, basal levels of LH, FSH, E2 and FSH, E2 on hCG day injected were not different, but LH level and endometrial thickness on hCG injected day were decreased significantly and the pregnancy rate was increased significantly in clomiphene citrate/GnRH antagonist group. CONCLUSION: The pregnancy rate was increased significantly in clomiphene citrate/GnRH antagonist group compared with natural ovulatory cycle and clomiphene citrate only group.

The author reviewed the effectiveness of triple procedure in terms of the visual acuity and the intraocular pressure control after 6 months follow up of twenty-four consecutive glaucoma patients who was treated with triple procedure: trabeculectomy with simultaneous lens extraction and intraocular lens implanation. At 6 months after operation, the mean intraocular pressure was 7.0mmHg lower than the preoperative level, and the kind of glaucoma medication was decreased from 2.1 to 0.6. The visual acuity improved in 67% at two months and 93% at six months after operation, respectively. The several complications such as hyphema, shallow anterior chamber with wound leaking, posterior capsular opacity and uncontrolled intraocular pressure were appeared. Effectiveness of triple procedure in terms of intraocular pressure control and visual acuity improvement seems to be similar to that of the operation done separately.

We experienced two cases of occupational asthma induced by Elk dander in Elk-feeders and confirmed these cases by the bronchial provocation test with Elk dander. Both of them showed dual asthmatic response. They also showed positive reaction to the skin prick test with EIK dander. Now one of them has no asthmatic symptoms at all after complete avoidnce of EIK dander.

PURPOSE: The purpose of the experiment with the rabbit was to evaluate the effect of human amniotic membrane transplantation in the extraocular muscle surgery area after the operation. METHODS: Five millimeters resection of both superior rectus muscles was performed in eight rabbits. The left eye was served as a control, and the right eye was covered with human amniotic membrane at the site where the operation was performed. Each rabbit was graded according to the degree of adhesion. A histological comparison was done after enucleation. RESULTS: At one week after the operation, it was discovered that the inflammation of the human amniotic membrane transplantation site was suppressed, but at two weeks the human amniotic membrane transplantation site was significantly inflamed. However, the inflammation decreased at six weeks. CONCLUSIONS: This study shows that strabismus surgery with transplantation of human amniotic membrane may reduce postoperative inflammation and adhesion in strabismus surgery after one week. However, after two weeks the inflammation will increase and produce more postoperative adhesion. After six weeks there was no significant inflammation in comparison to the control group.

Pneumocystis carinii causes serious pulmonary infection in immunosuppressed patients. This study was undertaken to observe the cytoskeletal proteins of P. carinii by immuno-electron microscopy. P. carinii infection was experimentally induced by immunosuppression of Sprague-Dawley rats for seven weeks, and their lungs were used for the observations of this study. The gold particles localized actin, tropomyosin, and tubulin. The actin was irregularly scattered in the cytoplasm of the trophic forms but was much more concentrated in the inner space of the cell wall of the cystic forms called the inner electron-lucent layer. No significant amount of tropomyosin was observed in either trophic forms or cystic forms. The tubulin was distributed along the peripheral cytoplasm and filopodia of both the trophic and cystic forms rather than in the inner side of the cytoplasm. Particularly, in the cystic forms, the amount of tubulin was increased and located mainly in the inner electron-lucent layer of the cell wall where the actin was concentrated as well. The results of this study showed that the cell wall of P. carinii cystic forms is a structure whose inner side is rich in actin and tubulin. The location of the actin and tubulin in P. carinii suggests that the main role of these proteins is an involvement in the protection of cystic forms from the outside environment by maintaining rigidity of the cystic forms.
