The cyclin-dependent kinase (cdk) inhibitor p27Kip1 gene is a powerful molecular determinant of cell cycle progression. Loss of expression of p27Kip1 has recently been shown to be predictive of disease progression in several human malignancies. The prognostic value and expression of p27Kip1 have been incompletely studied in bladder cancer. In this study, we investigated the relationship between p27Kip1 protein expression and clinicopathologic parameters in 50 cases of carcinoma of the urinary bladder by conducting immunohistochemical analysis and DNA flow-cytometry. Malignant bladder tissue demonstrated a heterogeneous pattern of p27Kip1 immunoreactivity. In addition, there was progressive loss of expression with increasing tumor grade. The expression of p27Kip1 protein was unrelated to stage, DNA ploidy and S phase fraction (SPF). SPF was unrelated with tumor grade and DNA ploidy. The results indicate that p27Kip1 is frequently expressed in well differentiated transitional cell carcinomas of the urinary bladder but less often expressed in muscle-invasive transitional cell carcinomas. The expression of p27Kip1 and its prevalence in low-grade tumors may reflect growth regulatory influences and potential inhibiting action in tumor progression and novel predictive markers of the biological potential of bladder tumors.

Angiogenesis is an early event in tumorigenesis and facilitates tumor progression and metastasis. This study was performed to evaluate the expression of vascular endothelial growth factor (VEGF), phospholipase C-gamma1 (PLC-gamma1) and Ki-67, and to assess the relationship between them in cervical squamous cell neoplasia. The materials were fifty cervical squamous cell lesions, consisted of thirty HSIL (6 moderate dysplasia, 11 severe dysplasia, 13 carcinoma in situ), and twenty invasive squamous cell carcinoma (ISCC) cases. Immunohistochemical stain for VEGF, PLC-gamma1 and Ki-67 were done. Expression rate of VEGF was significantly higher in ISCC than in HSIL (p=0.012). PLC-gamma1 expression was significantly higher in ISCC than in HSIL (p=0.004). Ki-67 labelling index was significantly higher in ISCC than in HSIL (p=0.001) and higher in VEGF-positive tumors than in VEGF-negative tumors (p=0.018), but there were no significant differences between PLC-gamma1 expression and Ki-67 labelling index (p>0.05), and between PLC-gamma1 and VEGF (p>0.05). This study suggests that PLC-gamma1 and VEGF may play an important role in tumor cell proliferation and invasion, and these may be a useful marker to predict the possibility of invasion in cervical cancer.

BACKGROUND: Hypertension is one of the frequent problems for which family physicians are well encountered to manage. Nonpharmacologic measures which include stress relaxation, low salt diet, weight reduction, moderation of alcohol intake, physical activity, tobacco avoidance are used as definitive or adjuvant therapy for hypertension. Family physicians should vigorously encourage their patients to adopt these life style modifications. This study was conducted to know how many nonpharmacologic treat,ment modalities are adopted by hypertensives and to find predicting factors. METHODS: A total of 100 of the hypertensive patients who are followed up via the department of family medicine, Hanyang University Hospital, from September 1995 through November 1995 are included in this study. A trained nurse interviewed patients according to the previously designed structured questionnaire. The overall response rate was 90% and the fill-up rate of the questionnaire was 100%. RESULTS: Sixty three patients were women. The mean age was 57.4 years(range, 20 to 84). Sixty one percent accompanied one or more other diseases, of which diabetes mellitus was the most common disorder. The mean systolic pressure was 143.9 mmHg and the mean diastolic blood pressure was 89.3mmHg. Ninty-three percent of patients received antihypertensives with compliance of 81 to 100%. Twenty four percent of patients adhered to regular exercise, 36 percent weight reduction, 48 percent low salt diet, 79 percent moderate drinking, 81 percent stress relaxation, and 87 percent no smoking. Of those six non-pharmacological treatments, 3.6 behaviors were adhered. Male patients were more attended with the low salt diet. Eleven patients of 2S alcoholics(44.0%) reduced their amount of alcohol intake and 8 of 17 smokers quitted smoking (47.1%) after they were diagnosed as hypertension. The mean BEPSI score was 1.5. Fifty one percent of patients had stress within the last three months, 32 percent had cumulative fatigue. The occupational stress was the most common one. All exercise which patients reported were isotonic. Seventeen percent of the patients took certain herb medicine or folk medicine. CONCLUSIONS: Of those 100 hypertensives who were treated at the department of family medicine, Hanyang University hospital, 24% adhered to regular exercise, 36 per cent weight reduction, 48 percent low salt diet, 79 percent moderate drinking, 81 percent stress relaxation, and 87 percent quit smoking in order. Of those six non-pharmacological treatments, 3.6 behaviors were adhered on the average. Nonpharmacologic treatment should be promoted by family physician as an important strategy for treatment of hypertension.

BACKGROUND: Blood pressures rneasured by a nurse at reception room as a part of routine physical examination are oft,en used as a indicator of medical care. Blood pressure at reception room and consultation room are, however, often different to each other and these differences are caused by various factors including difference of white coat effect by nurse and doctor. Thus, this study was performed in order to know whether blood pressure difference really exit, and its associated factors. METHODS: Two hundred ninety one patients who visited to one university hospital farnily practice were enrolled in this study. Blood pressure and pulse rate at reception room and consultation room, waiting t,ime, time interval between reception and consultation, smoking status, and intake of coffee and food were collected. Nine patients were excluded, because blood pressure either at reception room or at consulation room was not recorded. This study was performed by one nurse and two doctors. They defined the guideline for method of blood pressure measurement before the study, and used the same kind of indirect cuff sphygmomanometer. RESULTS: Two hundred eighty two patients were analyzed. The number of men was one hundred twenty five. Systolic blood pressure at consultation room was higher than that at reception room by 1.6+/-11.9mmHg (P<0.05). Sixty five cases(65%) in systolic blood pressure and 111 cases(40%) in diastolic blood pressure showed blood pressure differences more than 5mmHg. The group with systolic blood pressure difference between reception room and consultation room(SBP) in more than 5mmHg is more likely to be hypertensive than the group with SBP in less than 5mmHg(P<0.01). More female patients(66%) and hypertensive patients(59%) were belong to the group whose systolic blood pressure at consultation room were 5mmHg higher than at reception room(P<0.01). Twenty four patients(30%) of the group whose systolic blood pressure at reception room were 5mmHg higher than at consultation room had cigarette smoking within 1 hour, and this ratio was significantly higher than the other groups whose systolic blood pressure difference was less than 5rnmHg or systolic blood pressure at consultation room were 5mmHg higher than at reception room(P<0.01). There was relatively good concordance in classifying hypertension and normal blood pressure according to measurement site(Overall kappa, 0.747, P<0.01). CONCLUSIONS: Many patients showed blood pressure differences more than 5mmHg between reception room and consultation room. Systolic blood pressure at consultation room was higher than that at reception room, and there was relatively good concordance in classifying hypertension and normal blood pressure according to measurement site, but the adverse effect by misclassification should not be neglected. The importance as well as the limitation of blood pressure measurement at reception room should be considered in screening and treating hypertensive patient. Every time when blood pressure is taken, physicians should keep in mind to consider patients factors which may influence blood pressure level.

Five cases of intracranial lipoma diagnosed by MR are presented. MR imaging was performed on a 0.2T permanent unit using T1 weighted, proton density-weighted, and T2 weighted spin echo sequences. In two patients, gadolinium-enhanced T1 weighted image was also obtained. The lipomas were located dorsolaterally to the splenium of the corpus callosum (n=1), inferior to the splenium (n=2), in quadrigeminal plate(n=1) and in the presumed corpus callosum area in the case of agenesis of corpus call?um (n=1). The size and shape of the lipomas were variable. No contrast enhancement was seen in post contrast study. Sagittal T1 weighted image appeared to be the most useful imaging plane for the demonstration of the relationship between the lipoma ad the adjacent normal structures. The Homogenous signal intensity paralleling the fat signal and the characteristic location of the lesion are considered to be helpful in the differential diagnosis from dermoid cyst or teratoma.
