sodium hyaluronate in beagle dogs. METHODS:In group 1, hGH(Eutropin, r-hGH) 0.29mg/kg was injected subcutaneously to 6 beagle dogs everyday for 7 days. In group 2, 1mg/kg in sustained- release formulation using sodium hyaluronate(SR-hGH), was injected subcutaneously to 6 beagle dogs. In group 3, 2mg/kg of the same formulation(SR-hGH) was injected subcutaneously to 6 beagle dogs. Blood samplings were done for the measurement of GH and IGF-1 concentrations with ELISA kit(Diagnostic Systems laboratories, Inc., USA) RESULTS:GH concentration in group 1 was below 0.5ng/ml before injection and elevated to 98.1+/-15.7 at 1 hr, 124.2+/-15 at 2 hr, 57.8+/-18.1 at 4 hr, 23.8+/-4.8 at 6hr, 10.8+/-3.7 at 8 hr, 2.8+/-1.6 at 10 hr, 1.0+/-0.7 at 12 hr, and 0.5+/-0.1ng/ml at 24hr after injection. Peak GH concentration was observed in 2 hr and thereafter decreased progressively and returned to basal level at 10 hr after injection. From the 2nd day GH concentration was measured only at 6 hr after daily GH injection, indicating the values of 20.9+/-8.7, 16.2+/-14.9, 23.1+/-8.5, 34.3+/-9.9, 16.1+/-7.0, and 21.8+/-13.0ng/ml at 2nd, 3rd, 4th, 5th 6th, and 7th day, respectively. GH concentrations in group 2(SR- hGH 1mg/kg) were 136.7+/-22.8 at 1hr, 149.3+/-29.9 at 2hr, 110.6+/-17.8 at 4hr, 103.7+/-18.2 at 6hr, 108.3+/-21.0 at 8hr, 91.4+/-21.4 at 10hr, 79.6+/-15.9 at 12hr, 23.7+/-8.3 at 24hr, 5.5+/-1.5 at 30hr, 0.7+/-0.2 at 48hr, 1.4+/-1.4 at 54hr, and 0.5+/-0.1ng/ml at 72hr after injection. GH concentration was elevated above the basal level for 72hr with the peak at 2hr after injection of SR-hGH of 1mg/kg. GH concentrations in group 3(SR-hGH 2.0mg/kg) were 196.7+/-45.2 at 1hr, 219.4+/-39.8 at 2hr, 198.1+/-38.0 at 4hr, 196.0+/-31.4 at 6hr, 179.2+/-28.3 at 8hr, 151.8+/-19.5 at 10hr, 141.3+/-23.1 at 12hr, 72.9+/-14.7 at 24hr, 43.7+/-14.2 at 30hr, 3.8+/-1.6 at 48hr, 1.6+/-0.5 at 54hr, 0.8+/-0.5 at 72hr, 0.5+/-0.1 at 78hr, and 0.5+/-0.2ng/ml at 120hr. Peak GH concentration occurred at 2hr after injection and remained high concentration till 72hr and returned to basal level thereafter. IGF-1 concentrations in group 1 changed from 190.5+/-68.1ng/ml before injection, to 326.4+/-96.2, 346.4+/-79, 391.4+/-86.9, 417.0+/-96.1, 422.1+/-92.0, 429.9+/-86.4, and 478.0+/-90.2ng/ml at 12hr, 30hr, 54hr, 78hr, 102hr, 126hr, and 150hr, respectively. IGF-1 concentrations in group 2 were 128.5+/-37.0 ng/ml before and 268.0+/-64.2, 307.6+/-63.1, 374.8+/-55.3, 335.5+/-39.4, 301.9+/-44.8, 288.5+/-42.5, 272.8+/-51.8, 273.9+/-46.0, 251.1+/-40.9, and 239.2+/-45.0ng/ml at 24hr, 30hr, 48hr, 54hr, 72hr, 78hr, 96hr, 102hr, 126hr, and 150hr, respectively after injection. Peak IGF-1 concentration was measured at 48hr and remained in high concentration till 150hr after injection. IGF-1 concentrations in group 3 were 116.0+/-68.9ng/ml before and 365.5+/-118.6, 400.0+/-135.1, 463.6+/-138, 450.2+/-140.0, 337.2+/-122.4, 301.4+/-113.4, 236.3+/-89.1, 226.3+/-75.5, 148.9+/-55.2, and 129.8 48.4ng/ml at 24hr, 30hr, 48hr, 54hr, 72hr, 78hr, 96hr, 102hr, 126hr, and 150hr, respectively after injection. Peak IGF-1 concentration was at 48hr and remained in high concentration till 150 hr after injection. There was no significant difference in IGF-I conc between group I and group 3. CONCLUSION: Sustained-release form(1mg or 2mg/kg) of hGH with sodium hyaluronate released GH for 72 hours with the peak level at 2 hours and higher concentration of IGF-I above baseline maintained for 150 hour after injection with peak level at 48 hour. There was no difference in IGF-1 concentration between SR-hGH 1mg/kg and 2mg/kg injection. So sustained release form 1mg/kg will be more effective for GH therapy as weekly injection mode. More extensive study is needed to permit for new therapeutic application.

Abdominal cystic lymphangioma is a rare congenital malformation of lymphatics. Prognosis is excellent with exact diagnosis and complete surgical excision. The aughors analysed 10 US scans and 9 CT scans of surgically proven cystic lymphangiom for the last 5 years. US scan showed it as a septated cystic mass and 2 cases showed fluid-fluid level. CT scan showed a huge unilocular or multilocular density mass with uniformly thickened septae. A huge unilocular or multilocular cystic mass with uniformly thickened septae could suggest cystic lymphangioma would be differentiated from the other cystic masse.

BACKGROUND: To study the prognosis of patients with lung cancer, many investigators have reported the methods to detect cell proliferation in tissues including PCNA, thymidine autoradiography, flow cytometry and Ki-67. PCNA, also known as cyclin, is a cell related nuclear protein with 36KD intranuclear polypeptide that is maximally elevated in S phase of proliferating cells. In this study, PCNA was identified by paraffin-embedding tissue using immunohistochemistry which has an advantage of simplicity and maintenance of tissue architecture. The variation of PCNA expression is known to be related with proliferating fraction, histologic type, anatomic(TNM) stage, degree of cell differentiation, S-phase fraction and survival rate. We analyzed the correlation between PCNA expression and S-phase fraction, survival. METHODS: To investigate expression of PCNA in primary lung cancer, we used immunohistochemical stain to paraffin-embedded sections of 57 resected primary non-small cell lung cancer specimen and the results were analyzed according to the cell type, cell differentiation, TNM stage, S-phase fraction and survival. RESULTS: PCNA expression was dMded into five group according to degree of staging(-, +, ++, +++,++++). Squamous cell type showed high positivity than in adenocarcinoma. Nonsignificant difference related to TNM stage was noticed. Nonsignificant difference related to degree of cell differentiation was noticed. S-phase fraction was increased wit advance of PCNA positivity, but t could not reach the statistic significance. The 2 year survival rate and median survival time were -50% 13 months, +75% 41.3 months, ++73% 33.6 months, +++67% 29.0 months, ++++25% 9 months with statistic significance (P<0.05, Kaplan-Meier, generalized Wilcox). CONCLUSION: From this study. PCNA expression was high positive n squamous cell cancer. And, there was no relationship between PCNA positivity and TNM stage, cellular differentiation or S-phase fraction. But, the patients with high positive PCNA staining showed poor survival rate than the patients with lower positive PCNA. It was concluded that PCNA immunostaining is a simple and useful method for survival prediction in paraffin embedded tissue of non-small cell lung cancer.

Acute disseminated encephalomyelitis (ADEM) is a demyelinating disease of probable autoimmune etiology. The MR images of patients with clinically suspected ADEM were retrospectively reviewed. The clinical symptoms occurred 5 days to 1 month after viral upper respiratory infection (4) and Coxsakie viral infection(1). The symptoms had begun with fever(3), headache(3), sore throat(1), and drowsy mental state (1), which progressed with monophasic course to altered mental change(2), extremity weakness(2), seizure(1) and/or cerebellary symptom(I) MRI findings of ADEM showed patchy(4), nonhemorrhagic(5), asymmetric(5) high signal intensity lesions on T2-weighted images. The number of the lesions was mostly multiple(4). The lesions mainly involved the brain stem(3) and subcortical white matter(3). Follow-up MR images of 13 days to 20 days after high dose steroid therapy showed marked improvement in two of three, which well correlated with clinical manifestations. MR findin of multiple, patchy, nonhemorrhagic and asymmetric lesions in subcortical white matter and brain stem on T2-weighted images seem to be characteristic features of ADEM, but nonspecific. Therefore, clinical correlation is required in evaluating ADEM.
