A lg year-old female patient with pityriasis lichenoides et varioliforrnis acuta (PLEVA) was been treated with PUVA, At first, she was treated with tetracycline for 8 weeks with improvement somewhat. But 2 months later, her skin lesions aggravated slowly. So, we tried to treated her with PUVA and then she was cleared completely. The initial dose of UVA was 5 J/cm The UVA dosage increased by 10g of the previous exposure and increased to the maximum dose, 15 J/cm The patient exposed to UVA R times per week. 12 times after the PUVA therapy, the skin lesions begin to improve and completely improved at 21 times of Pl.JVA therapy. She was followed up every week and there was no side effect except hyperpigrnentation till 24 months. The total dose during treatment is 210 J/cm.

Liquid crystal thermography is a new diagnostic imaging method detecting the temperature change by the physiologic disturbance as compared with the radilogic method detecting the anatomical distortion. We have used liquid crystal thermography in 54 patients with complaining low back pain during the period form 2nd. March 1989 to 30th. April 1989. Of these 54 patients, 35 had myelography and C-T scan, 23 had EMG, and 13 were operated upon. 1. There were 35 clinically positive patients on whom concomitant myelography and C-T scan was performed; 32 patients(91%) had a positive myelography and C-T scan, and 30 patients (86%) had a positive thermography. Of these 35 patients, 23 had EMG concomitantly; 17 patients(74%) had a positive EMG and 18 patients(78%) had a positive thermography. 2. Liquid crystal thermography correlated with myelography and C-T scan in 31 patients(89%), EMG in 18 patients(78%). 3. Concomitant thermography, myelography and C-T scan, and surgery were performed on 13 patients among them EMG was added on 5 patients; Myelography and C-T scan had 100% accuracy, thermography had 92% accuracy, and EMG had 80 % accuracy. 4. Liquid crystal thermography is non-invasive method, dose not involve the use of ionizing radiation, and correlates well with clinical and surgical findings and other diagnostic methods, and costs relatively low. So, liquid crystal thermography is useful and reliable diagnostic method in patients with low back pain.

PURPOSE: We evaluated the ability of endo-rectal coil MRI (ER-MRI) to predict the local pathological stage of prostate cancer prior to radical prostatectomy and compared the results with those of transrectal ultrasonography (TRUS). MATERIALS AND METHODS: ER-MRI using high field magnets (1.5 Tesla) were performed in 22 patients (mean age 62.8 years, range 51-73) with clinically localized prostate cancer before radical prostatectomy. Of the 22 patients, 17 patients were also assessed by TRUS. The results of the imaging techniques were compared with the post-operative histopathological findings. As one patient with pelvic lymph node metastasis, which was detected on frozen-section examination during surgery, was spared radical prostatectomy, the final evaluation included 21 patients. RESULTS: DSeven of the 21 patients (33%) were found to have extraprostatic extension (EPE), and 5 had seminal vesicle invasion (SVI). The sensitivity and specificity for diagnosing EPE using ER-MRI were 62.5% and 84.6%, respectively, and 16.7% and 100% with TRUS. The sensitivity and specificity for diagnosing SVI were 80.0% and 93.8%, respectively with ER-MRI, and 0% and 92.3% with TRUS. The accuracy of predicting SVI was 90.5% with ER-MRI compared to 70.6% with TRUS. CONCLUSIONS: ER-MRI was significantly better than TRUS for determining the local extent of prostatic cancer and for prediction of SVI in the preoperative staging of clinically localized prostate cancer.

The cause of osteoporosis are multifactorial; these include aging, immobilization, genetic fsctor, initial bone mass, nulliparity, postmenopause, cigarette, etc. Among them the hormonal factors are very important. It is worthwhile to study the effects of various hormones on bne cells. Authors evaluated the effects of TGB-B, 17-B estradiol, insulin, and human growth hormone as a stimulatory factors, and r-interferon as a inhibitory factor on the MC3T3 osteoblast cells with measurement of cell numbers, osteocalcin and 3[H]-thymidine incorporation. 1. TGF-B was a potent stimulator on ostoblast with increased change in cell morphology (number, size, shape), osteoclacin level and 3[H]-thymidine incorporation in dose depen- dant fashion. 2. 17-B estradiol was also a potent stimulator on osteoblast activity as well as TGF-B except osteoclacin level which w#as not shown in dose dependant fashion. 3. There were little changes on osteoblast with insulin, growth hormone, and r-interferon. Through this study it is confirmed that TGF-B and 17-B estradiol showed marked stimulatory effect on osteoblast cell in vitro.

This review-article is aimed at shedding a light upon the nature of age-associated changes in the human skeletal system. When the anatomical, physiological and biochemical consequences of bone aging are considered together with the hardening, drying and the diminished repair capabilities of the elderly, it can be seen that fractures assume greater importance as a clinical problem in the geriatric population. Older people start out with a deficit of cortical bone, making them more fracture prone and once fractures occur, the necessary treatments (immobilization, use of casts, etc.) accelerate the rate of bone loss. In addition, aged individuals stand a higher risk for complications of the hospital and enforced bed rest that may ensue. The problems resulting from bone loss in the elderly may be partially alleviated by providing adequate health service support which should include consideration of the following points : 1. Age, sex and general health status ; 2. Habits and inclinations towards physical activities ; 3. Nutritional and endocrine background ; 4. Presence of any specific bone diseases, including osteoporosis, osteoarthritis, osteomalacia and ankylosis ; 5. Psychosocial adaptability and other behavioral elements.

BACKGROUND: As an antihypertensive drug, Nifedipine, a calcium channel blocker was introduced recently, which also has antianginal effect. But due to the relatively short duration of action, another antihypertensive agents having longer duration of action and stronger hypertensive effect were under investigation. Nilvadipine, a new calcium channel blocker, was introduced to have more prologned duration of action and to act more specifically on vascular smooth muscle. So the efficacy and safety of oral Nilvadipine on essestial hypertension was investigated and represented by our institute. METHODS: In order to investigate the efficacy and safety of oral Nilvadipine, daily doses of 4mg twice a day were administered in 30 hypertensive patients whose states were compatible to the criteria : 1) severity of hypertension rated in Stage I and Stage II according to the classification by WHO, 2) ages ranging from 30 to 74 years regardless of sex, 3) blood pressure with 95mmHg or higher but less than 115mmHg in diastolic pressure which was the mean in a sitting position at the last two out of not less three consultations in the 2 week observation period, 4) outpatients with informed consent for 6 weeks. Blood pressure and heart rate were measured every 2 weeks. The complete with blood count with platelet, uronalysis and the electrocardiography were performed at the beginning period and the 6th weeks of therapy. And kinds of side effects were questioned by examining physicians. RESULTS: The following results were obtained : 1) Blood pressure fell significantly in 6 weeks of treatment with Nilvadipine(Mean pressure+/-S.D., 6.00mmHg vs 108.90+/-9.68mmHg p<0.05), 2) There was no significant change in EKG in 6 weeks of treatment with Nilvadipine, 3) Pulse rate was decreased in 6 weeks of treatment with Nilvadipine(80.14+/-11.90/min vs 75.39+/-6.47/min, p<0.05). 4) No significant chsange in body weight was observed(64.50+/-8.7kg vs 63.50+/-10.25kg, p<0.05). 5) There were no significant changes in blood chemistry including blood sugar, cholesterol, electrolytes, serum creatinine and alkaline phosphatase values, 6) Hematologic findings and urinalysis findings reamained unchanged, 7) Total 10 patients(33.30%) had various side effects;facial flushing 30.00%, palpitation 23.33%, headache 20.00%, nausea 10.00%, drowsiness 3.33%, heaviness 3.33% and indigestion 3.33%. But there was no serious side effect that requires to discontinue the medication of the test drug. And there was no need to reduce the dosage due to the side effect, 8) The antihypertensive effect was judged to decrease markedly in 76.70%, decrease 20.00%, unchange 3.30% and increase 0.00%, 9) The utility which was assessed with the data from the overall safety and antihypertensive effect, the drug was judged to be very useful in 60.00%, useful 33.30%, useless 6.67% and inhibited 0.00%. CONCLUSION: From the above results, Nilvadipine in doses of 4mg twice a day was effective and useful in most cases without severe side effects in essential hypertensive patients with diastolic blood pressure of 95 to 115mmHg.

In order to evaluate antitumor rnechanisms of interleukin (IL)-12/IL-2 that has been shown significant tumor suppressive activity on established primary and metastatic Renca tumor, we studied chemokine gene expression induced by direct action of IL- 12/IL-2 or cytokine cascade. IL-12/IL-2 induced gene expression of interferon gamma (IFN-r) and granulocyte monocyte-colony stimulating factor (GM-CSF) in splenocytes, and it induced gene expression of monokine induced by IFN-r (Mig), interferon inducible protein 10 (IP- 10), SDF-1, macrophage inflammatory protein (MIP)-1a, MIP-1B, MIP-2, monocyte chemotactic protein (MCP)-1, and Rantes in tumor mass. However IL-12/IL-2 could not induce these chemokines in tumor mass of GKO mice and Renca cell in vitro. IL- 12 also did not increased chemokine gene expression in Renca cell in vitro, but IFN-r induced gene expression of Mig, IP-10, MCP-1 in Renca cell in vitro. In the chemotaxis assay, culture supernatant of Renca cell stimulated with IFN-r increased splenocyte migration in vitro. All these data suggest IL-12/IL-2 can induce IFN-r-chemokine cascade in tumor mass, and Mig, IP-10, MCP-1 produced from tumor cell may play an important role for initial immune cell migration into tumor mass.
