Recently, it has been postulated that diabetic autonomic neuropathy is caused by reduction in availability of nerve growth factor (NGF) in enteric nervous system. This experiments were performed to determine the changes of the distribution of enteric neuropeptide by diabetes and these changes could be prevented by administration of NGF. Sprague Dawley rats (200~250gm) were made diabetic by a single intraperitoneal injection of streptozotocin 65 mg/kg in saline. Recombinant human NGF (Sigma, Co., Ltd.) were administered at a dose of 500ng/kg subcutaneously every day for consecutive 4 weeks after streptozotocin administration. After 4 weeks, rats were anesthetized with ether and perfused with 4% paraformaldehyde. ileum was dissected and prepared by whole mount preparation method. Prepared segments were immunostained for substance p, calcitonin gene-related peptide, vasoactive intestinal peptide, and galanin by PAP technique. For the observation of the interstitial cells of Cajal, segments were immersed in Champy-Maillet solution for 2 days Results obtained were as follows: 1. In myenteric plexus of diabetic rats, substance P-like and VIP-like immunoreactivity were not changed compared with that of the control group. CGRP-like and galanin-like immunoreactivity were decreased in diabetic group and immunoreactive cells for CGRP and galanin were also decreased 18.1% (P<0.01) and 43.7% (P<0.01) respectively. 2. In NGF administerd diabetic group, immunoreactivity of substance p, VIP, galanin in myenteric plexus were slightly increased and immunoreactive cells for substancre p, VIP, galanin were almost the same as that of the control group. However, immunoreactive cells for CGRP of myenteric plexus were not changed by NGF. 3. In submucous plexus of diabetic rats, immunoreactivity of all four neuropeptides(substance p, CGRP, VIP, galanin) were decreased compared with that of the control group. Immunoreactive cells for substance p, CGRP, VIP, and galanin were also decreased in 38.8%, 77.6%, 33.0%, and 35.7%, respectively (P<0.01). 4. In NGF administered diabetic group, immunoreactivities of substance p, VIP and galanin in submucous plexus were increased and the immunoreactive cells were increased significantly compared to diabetic group. However, immunoreactive cells for CGRP of submucous plexus were not changed by NGF. 5. Interstitial cells of Cajal of diabetic group were decreased 7.4% ovoidal cells (A type) and 28.3% round cells (B type) In NGF administered group, the morphology and the number of ICC were not different to the control group. With the above results, it could be assumed that NGF prevent the damage of neurotransmitter and ICC in enteric nervous system.

Total cholesterol and triglyceride were measured in sera of 40 cases of hypertension, 22 cases of myocardial infarction, 14 cases of cerebral thrombosis, 18 cases of subarachnoidal hemorrhage and 30 cases of normal control in Chungnam national University Hospital from October 1980 to September 1981, and the results are as follows; 1) The mean serum total cholesterol and triglyceride levels in normal control group are 153.57+/-40.60mg% and 150.82+/-51.76mg%. 2) The age incidence of these diseases were highest in 6th decade. 3) Serum cholesterol levels of myocardial infarction, hypertension, cerebral thrombosis and subarachinoidal hemorrhage group were higher than that of normal control group. 4) Serum triglyceride levels of acute myocardial infarction and hypertension were significantly higher than that of normal control group, but there is only slightly increases in cerebral thrombosis and subarachinoidal hemorrhage. 5) In general, serum lipid levels are higher in cardiovascular diseases(hypertension and myocardial infarction) than cerebrovascular diseases(cerebral thrombosis and subarachnoidal hemorrhage). 6) Serum Cholesterol and triglyceride levels decreased by administration of pancreatic mucopolysacharide for 1 or 2 months. In conclusion, it seems that high serum cholesterol and triglyceride level may play and important risk factor in development of hypertension and myocardial infarction.

PURPOSE: The present study examined the risk of intraocular infection only in cases where the injection needle was replaced when the injection needle was contaminated before intraocular injection. METHODS: Staphylococcus aureus and Staphylococcus epidermidis were cultured and smeared on the end of 30 syringe needles containing 0.1 mL normal saline. After removing only the injection needle, the normal saline in the syringes was injected onto blood agar plates and cultured. RESULTS: The culture results were positive in 21 out of 30 samples in the group smeared with Staphylococcus aureus, and in 25 out of 30 samples in the group smeared with Staphylococcus epidermidis. CONCLUSIONS: When the injection needle is contaminated, the replacement of the needle does not eliminate the possibility of intraocular infection.

OBJECTIVE: The authors evaluate the usefulness, results, and technical problem of endovascular treatment of cerebral aneurysms with Guglielmi detachable coil(GDC). METHODS: Forty patients with 31 ruptured and 11 unruptured aneurysms were treated with GDC embolization. Twenty-four aneurysms were located in the anterior circulation and 18 in the posterior circulation. Aneurysms size was categorized small(n=31) or large(n=11) and neck size was categorized narrow(n=30) or wide(n=12). We statistically analyzed occlusion rate according to the location, rupture, size, and neck size of aneurysms, and investigated the procedure-related complications and clinical outcomes. RESULTS: GDC treatment of aneursyms was successful in 40 aneurysms of 39 patients(95.2%). Total occlusion was achieved in 24(60.0%) cases, subtotal occlusion in 12(30%), and incomplete occlusion in 4(10.0%). Each total occlusion rate was 69.0% in small-sized, 36.4% in large-sized, 69.0% in narrow-necked, and 36.4% in wide-necked aneurysms. Location and rupture of aneurysms did not influence occlusion rate. The technical complications included 4 thromboembolisms, 3 parent artery occlusions, and 1 perforation of aneurysm. Procedure-related morbidity and mortality were 10.3% and 2.6%. 3 subtotally or incompletely embolized aneurysms in posterior circulation rebled during the follow-up period. CONCLUSION: The results of this study indicate that endovascular GDC treatment is an appropriate therapeutic alternative in cerebral aneurysms. However, the rebleeding by aneurysmal recanalization or regrowth is a major limitation of GDC treatment. Follow-up angiography and further technical improvement are mandatory to overcome rebleeding.

Methods:
Thirty-six patients with calcific tendinitis of the shoulder treated by US-guided barbotage with a spinal needle and subacromial steroid injection were included in the study. We evaluated clinical outcomes based on American Shoulder and Elbow Surgeons (ASES) score, Constant score, and visual analog scale (VAS) for pain score. Radiological outcomes were assessed by X-ray imaging at each visit.
Results:
Our results showed that US-guided barbotage and subacromial steroid injection produced good clinical and radiological outcomes in patients with calcific tendinitis of the shoulder. Of the 36 patients, only one required surgical treatment, while the others showed improvement without any complications. Compared to values before the procedure, calcific deposit size and VAS, ASES, and Constant scores showed significant improvement 6 weeks after the procedure. No significant correlation was found between the initial calcific deposit size and clinical outcomes at each time point.
Conclusions
In patients with calcific tendinitis of the shoulder, US-guided barbotage using a spinal needle and subacromial steroid injection can yield satisfactory clinical and radiological results.

Recently diabetic neuropathy has been postulated to occur from reduced availability of neurotrophic factor. This experiment was performed to identify the effect of nerve growth factor on dorsal root ganglia (DRG) in the strepto-zotocin-induced diabetic rat using morphometry and immunohistochemistry. The results obtained are as follows : 1. Unlike in the diabetic group where the type A and B cells were significantly decreased in their total numbers and sizes, these cells were normal in NGF-administered diabetic group. 2. Numbers of cells immunoreactive with SP and CGRP were also significantly decreased in the diabetic group. However, the NGF-administered diabetic group did not show any reduction in the number of these cells. 3. Mean sizes of cells immunoreactive with SP and CGRP cells were reduced in the diabetic group by 18.1% and 26.6% respectively (P<0.01). On the other hand, in NGF-administered diabetic group, mean sizes of SP-immunoreactive cells were increased (10.5%) which was not statiatically significant, and those of CGRP-immunoreactive cells were decreased (18%) compared to the control group (P<0.01). 4. In the diabetic group, many of nerve cell bodies showed some degenerative characteristics including neuron-satellite cell interface of irregular shape, the presence of a number of vacuoles and dense bodies, and nucleus of irregular contour. However, NGF-administered diabetic group exhibited neuron-satellite cell interface of regular form, many neurofilaments and neurotubules, and normal intracellular organelles. These results suggest that administration of NGF protects spinal ganglion cells from morphometric and morphological changes which are associated with a streptozotocin -induced diabetic neuropathy.

BACKGROUND: Corticosteroids are known to be significant prognostic parameters in sepsis. Recently, an absolute and relative insufficiency of the corticosteroids system has often been reported to often develop particularly in severe sepsis. Degree of such an adrenal insufficiency not only has prognostic implications but also can be used to guide corticosteroids replacement therapy. The 24-hour urinary cortisol levels as well as serum cortisol concentrations were measured to assess the clinical significance and their relationship with the other parameters of sepsis, and also evaluated the clinical implications of the relative adrenal insufficiency. METHODS: 26 consecutive patients with sepsis were enrolled. The basal random serum cortisol, ACTH, ADH, lactate levels and 24-hour urinary free cortisol amount were measured. The rapid ACTH (250 microgram) stimulation test was also performed. RESULTS: Basal serum cortisol levels were higher in the non-survivors than in the survivors. The 24-hour urinary free cortisol levels were higher in the patients with severe sepsis than in those without. The serum cortisol levels strongly correlated with the serum ADH and lactate levels. The 24-hour urinary free cortisol levels strongly correlated with the serum cortisol and lactate levels. The fractional changes in the cortisol levels after the rapid ACTH stimulation tests correlated with the serum cortisol, ADH, and lactate levels. CONCLUSION: Both the serum cortisol and 24-hour urinary cortisol were found to be significant prognostic factors in sepsis, and showed a strong correlation with the other parameters. The relative adrenal insufficiency might also be an important clinical parameter.

Background:
The purpose of this study was to analyze the epidemiology of T-score discordance between the spine and femur in the South Korean population and compare the prevalence of T-score discordance between the Korean osteoporosis population and atypical femoral fracture (AFF) patients.
Methods:
A total of 12,422 subjects from the Korea National Health and Nutrition Examination Survey were reviewed retrospectively. T-score discordance was defined as a difference of ≥ 1 standard deviation between the lumbar spine (LS) and femoral neck (FN) bone mineral density (BMD). The prevalence of T-score discordance (low LS [LS BMD < FN BMD], low FN [LS BMD > FN BMD], and total [low LS + low FN]) was investigated in the osteoporosis and non-osteoporosis groups and stratified by sex and age. Tscore discordance of 63 patients with AFFs diagnosed at a single institution was compared with that of the Korean osteoporosis population using propensity score matching.
Results:
T-score discordance was prevalent in the Korean osteoporosis population (44.8%), and low LS discordance (37.5%) was more frequently seen than low FN discordance (7.2%) (p < 0.001). The prevalence of total and low LS discordance was significantly higher in AFF patients than in the Korean osteoporosis population (total discordance: 69.8% and 42.5%, respectively; low LS discordance: 63.5% and 31.7%, respectively; p < 0.001).
Conclusions
T-score discordance was highly prevalent in the Korean osteoporosis population, and low LS discordance was more common than low FN discordance. Nevertheless, the prevalence of low LS discordance was significantly higher in AFF patients than in the Korean osteoporosis population.
