The effects of autonomic drugs on the activities of the upper urinary tract were studies with the ureteral perfusion pressure method.It was found that a-adrenergic and M-cholinergic receptors possess excitatory effect on the upper urinary tract while ?-adrenergic receptor possess inhibitory effect.It is likely that a-adrenergic receptor plays a certaion role in the maintenance of the normal activity of the upper urinary tract but both the M-and ?-receptors have a little effects.The effects of the autonomic nervous system and its receptors on the activities of the upper urinary tract were discussed.

Objective To investigate the different influences of simvastatin on proliferation of rat smooth muscle progenitor cells(SPCs) versus endothelial progenitor cells (EPCs) and identify the compounds that differentially inhibit SPCs and EPCs proliferation for clinical usefulness. Methods Total mononuclear cells (MNCs) were isolated from bone marrow of rats by Fieoll density gradient centrifugation, and then the cells were plated on fibronectin-coated culture dishes. SPCs outgrew from the culture of MNCs in the presence of platelet-derived growth factor-BB and basic fibroblast growth factor, whereas EPCs were obtained in the presence of vascular endothelial growth factor. SPCs were identified as adherent cells positive for α-smooth muscle actin (α-SMA) by indirect immunofluoreseent staining. EPCs were characterized as adherent cells double positive for DiLDL-uptake and lectin binding by direct fluorescent staining. SPCs and EPCs were stimulated by simvastatin (0.01~10.00 μmol/L) or vehicle control for the respective time points (6 h, 12 h, 24 h and 48 h). SPCs and EPCs proliferation were assayed with 3H-TdR incorporation and manual counting respectively. Results Simvastatin obviously inhibited SPCs proliferation. At the concentration of 0. 01 μmol/L for 12 h,simvastatin significantly reduced the number of SPCs by (5.8±3.1)% compared with control group (P<0.05). Simvastatin significantly stimulated EPCs proliferation, which was dose- and time dependent and reached maximum at 1 μmol/L after 24 hours (2.0±0.1 fold increase, P<0.01).Conclusions Simvastatin displays different effects on SPCs (inhibited) and EPCs (promoted)proliferation. Local application of simvastatin may inhibit arterial restenosis and promote reendothelialization of injured vessels.

AIM: To investigate the feasibility of reendothelialization of the injured arterial wall by autologous endothelial cell transplantation and their influences on neointima proliferation. METHODS: New Zealand white rabbits (n=30) were subjected to bilateral iliofemoral artery balloon injury. Cultured, autologous venous endothelial cells were immediately transplanted into one vessel(transplantation group), whereas the contralateral artery received medium only(control group). Reendothelialization of the injured arterial wall was analysed 4 hours or 4 days after cell transplantation by fluorescent tracing、scanning electron microscope(SEM) and Evans blue staining. Pathology analysis was employed 28 days after cell transplantation to evaluate neointima proliferation. RESULTS: The transplanted endothelial cells had adhered into the aterial wall 4 hours after transplantation and began to attach and spread 4 days later. A number of fluorescent labeling endothelial cells were observed in the endothelial injured arterial wall. The vessels in control group were stained nearly completely by Evans blue, whereas about 60% area was not stained in transplantation group. Pathological examination demostrated that neointimal area and maximal intima thickness in transplantation group significant decreased than those in control. CONCLUSION: Autologus endothelial cells were effectively transplanted into the injured arterial wall by balloon catheter, and it can relieve neointima proliferation in the long time.

PURPOSE: Pain is the most common and influential symptom in cancer patients. Few studies concerning pain intensity in the terminally ill cancer patients have been done. This study aimed to identify factors related with more than moderate pain. METHODS: This study used secondary data of 162 terminal cancer inpatients at the palliative ward of six training hospitals in Korea. Physician-assessed pain assessment was by 10 point numeric rating scale. Substantial pain was defined more than moderate intensity by the Korean National Guideline for cancer pain. The Korean version of the MD Anderson Symptom Inventory was self-administered to assess symptoms. Survival prediction was estimated by the attending physicians at the time of admission. RESULTS: Less than six weeks of predicted survival and more than numeric rating of six for worst drowsiness in the previous 24 h were significantly related to substantial pain (P=0.012 and P=0.046, respectively). The dose of opioid analgesics was positively related to substantial pain (P=0.004). CONCLUSION: Factors positively related to substantial pain were less than six weeks of predicted survival and considerable drowsiness. Careful monitoring and active preparation for pain are required in terminal cancer patients having those factors.

The purpose of this study was to describe the CT findings of focal organizing pneumonia and to compare the findings with pathology. CT findings of histologically proven focal organizing pneumonias in 26 consecutive patients were analyzed. In 17 patients who had undergone surgical resections, the findings were correlated with pathology. Focal organizing pneumonias appeared as a nodule (n= 13) or a mass (n=13), ranging from 9 mm to 66 mm in diameter. Ground-glass opacity was seen in 6/13 (46%) nodules and 6.5/13 (50%) masses (k=.48) with an extent ranging from 5% to 75% (mean, 16%). In 4/26 (15%) patients, the extent was more than 50% of the lesion. They showed smooth (n=4), lobulated (n=8), spiculated (n=1), or lobulated and spiculated margin (n=13). On correlative analysis, nodule or mass on CT consisted histologically of intraalveolar exudate or microabscess, chronic inflammatory cell infiltration, fibrotic nodules, and polypoid granulation tissue in the alveolar or bronchiolar spaces. Ground-glass opacity consisted of interstitial fibrosis and chronic inflammatory cell infiltration and intraalveolar polypoid granulation tissue. Focal organizing pneumonia may simulate a lung cancer with variable appearances on CT and the findings reflect underlying histopathology of the disease.

OBJECTIVE: To determine the effects of cervical kyphosis on the recovery of swallowing function in subacute stroke patients. METHODS: Baseline and 1-month follow-up videofluoroscopic swallowing studies (VFSSs) of 51 stroke patients were retrospectively analyzed. The patients were divided into the cervical kyphosis (Cobb's angle <20°, n=27) and control (n=24) groups. The penetration-aspiration scale (PAS), American Speech-Language-Hearing Association National Outcomes Measurement System swallowing scale (ASHA NOMS), and videofluoroscopic dysphagia scale (VDS) were used to determine the severity of dysphagia. Finally, the prevalence of abnormal VFSS findings was compared between the two groups. RESULTS: There were no significant differences in baseline PAS, ASHA NOMS, and VDS scores between the two groups. However, the follow-up VDS scores in the cervical kyphosis group were significantly higher than those in the control group (p=0.04), and a follow-up study showed a tendency towards worse ASHA NOMS scores (p=0.07) in the cervical kyphosis group. In addition, the cervical kyphosis group had a higher occurrence of pharyngeal wall coating in both baseline and follow-up studies, as well as increased aspiration in follow-up studies (p<0.05). CONCLUSION: This study showed that stroke patients who had cervical kyphosis at the time of stroke might have impaired recovery from dysphagia after stroke.
