Vimentin is an intermediate filament protein normally expressed in mesenchymal cells, but the evidence of the aberrant expression of vimentin in epithelial cancer cells suggests that the vimentin expression might be related to local invasiveness and metastatic potential. There have been a few previous studies on the vimentin expression in human cervical carcinogenesis using in vivo and in vitro models. We examined the immunohistochemical vimentin expression in various squamous epithelial neoplasms of the uterine cervix, including the cervical intraepithelial neoplasia group (n=25), the microinvasive squamous cell carcinoma group (n=15), the invasive squamous cell carcinoma group (n=15) and the metastatic squamous cell carcinoma group (n=8). Vimentin positivity was significantly higher in the invasive than in the intraepithelial group, and in the cases with lymph node metastasis than in those without metastasis, suggesting a relationship between the vimentin expression and progression of the uterine cervical epithelial tumors.

BACKGROUND: Sustained-release theophylline, which is generally prescribed as a twice-daily equal-dose regimen, is one of the more common asthma treatments. the development of a sustained-release drug delivery technology that enables improved control of the theophylline blood levels represents a significant advancement in both the efficacy and safety of dosing. METHOD: A crossover study was conducted with 25 adult chronic asthmatic patients requiring daily bronchodilator therapy. The study group included thirteen males and twelve females with ages ranging from 19 to 71 years. The overall approach was to place the patients first on the twice-daily preparation(Etheophyl®) for 28 days at 8 AM and 8 PM, and measure the pulmonary function and theophylline level on the 28th day. the patients were subsequently switched to the once-daily preparation(Uniphyl®) in the same daily dose at 8 PM on the 29th day and the same parameters were measured on the 56th day. RESULTS: the mean serum levels of theophylline were 8.18±1.66µg/ml in the Etheophyl®-treated period and 8.00±1.75µg/ml in the Uniphyl®-treated period. In addition, the FEV1 showed 71.40±7.48 percent in the Etheophyl®-treated and 69.18±9.00 percent in the Uniphyl®-treated period. Thus there were no significant differences between the once-daily and twice-daily preparation. CONCLUSION: The results indicated little clinical differences between the two medication. The two drugs are equally effective in controlling asthma over the four weeks of treatment.

This study included fifty two premature babies in whom EEG was performed at National Medical Center, from Jan. 1990 to Jun. 1991. clinical and EEG records of all subjects were analyzed and the following results were obtained. 1) The day of first EEG performed were;11 cases within 10 days, 20 cases from 11 days to days, 13 cases from 21 days to 30 days and 8 cases beyond 31 days. 2) The results of first EEG were; within normal limit in 34 cases, mild abnormality in 3 cases, moderate abnormality in 11 cases and marked abnormality in 4 cases. 3) The abnormal EEG ratio according to the sex was higher in female than in male (43.5% vs 27.6%). 4) The abnormal EEG ratio according to the gestational age was higher in shorter gestational age group than in longer gestational age group (40.9% under 32 weeks of G.A. vs 30.0% beyond 33 weeks of G.A.). 5) The abnormal EEG ratio according to the birth weight was not significant. 6) The abnormal EEG ratio according to the ventilator use was higher in used group than in not used group (38.5% vs 30.8%). 7) Combined diseases in 18 cases of abnormal EEG group were jaundice (14 cases), hyaline membrane disease (7 cases), asphyxia (4 cases), anemia (4 cases), hydrocephalus, sepsis, PDA, hypocalcemia, UTI and IVH. 8) The mean apgar score in abnormal EEG group was lower than normal EEG group both in one minute and five minute. 9) Two cases among 18 cases of abnormal EEG group showed abnormal brain sonographic findings, but one case among 34 cases of normal EEG group showed abnormal brain sonographic finding. 10) Ten cases were followed up with serial EEG, six cases of which were treated with anticonvulsant. We observed normalization of the EEG in 5 cases of anticonvulsant treated group.

Fetal teratomas rarely complicate pregnancy,having an incidance of only 20,000:1 to 40,000:1 of live births. Overthere, cervical teratomas are rare and accounts for only 5.5% of all neonatal teratomas. We have experienced a large cervical immature teratoma and present this case with a brief review of literatures.

Bovine growth hormone (bGH) gene was expressed in an insect spodoptera frugiperda cell line using a Baculovirus, Hyphantria cunea nuclear polyhedrosis virus (HcNPV). The bGH gene in pbGH plasmid was sequenced and amplified by PCR technique with two primers containing NcoI sites. The bGH gene consisted of 654 bp (217 amino acid residues), the 5'-untranslated region of the cloned bGH cDNA contains 56 bp, and the 3'-untranslated region contains 145 bp and two pallindromic regions. The amplified bGH gene DNA fragment (654 bp) was inserted into the NcoI site of the pHcEVII vector, which was named pHcbGH. The pHcbGH transfer vector DNA and the wild type HcNPV DNA were cotransfected into s. frugiperda cells to construct a recombinant virus. Eight recombinant viruses were selected and named HcbGH. One clone, HcbGH-4-1 showed largest plaque size, therefore the recombinant virus was further studied. The multiplication patters of the recombinant HcbGH-4-1 was similar to that of the wild type HcNPV. The bGH gene DNA in the HcbGH-4-1 recombinant was confirmed by Southern lot hybridization. The amount of the bGH (217 amino acid residues, 21 kDa) produced in S. frugiperda cells infected with the HcbGH-4-1 recombinant was approximately 5.5 ng per ml (106 cells) by radioimmunoassay.
