2.Studies on Total Exchangeable Sodium and Plasma Volume in Hypertension.
Korean Circulation Journal 1975;5(2):1-20
Total exchangeable sodium and plasma volume were measured to evaluate role of sodium in hypertension by radioisotope 24 Na and Evans blue in 25 patients with essential hypertension, 10 with malignant hypertension, 5 with renal hypertension and 15 normal controls. The results obtained are as follows. 1. The total exchangeable sodium content was 35.8+/-3.5mEq/kg in normal controls, 35.6+/-2.7mEq/kg in essential hypertension and 36.2+/-3.5mEq/kg in renal hypertension revealing no statistical significance in difference. In malignant hypertension, it was 44.9+/-2.0mEq/kg and it was markedly elevated than in normal controls. 2. Plasma volume in normal controls was 44.0+/-4.7ml/kg. In essential hypertension there was two groups, one (group II, 35.2+/-5.6ml/kg) was slightly lower than the other (group I, 43.2+/-4.8ml/kg). In malignant hypertension, it was 56.9+/-7.5ml/kg revealing significant increase than in normal controls. 3. Changes of the total exchangeable sodium content was observed after the administration of hydrochlorothiazide 50mg in normal controls and essential hypertension. In normal controls there was no statistical significance in reduction. In essential hypertension, initially low salt group (group II) showed no significant reduction and the other group (group I) showed significant reduction with depression on blood pressure. 4. Long term therapy with hydrochlorothiazide 50mg for 2~3 months in the group of hypertension who responded well with short term therapy (group I), the contents of exchangeable sodium reduced significantly than normal controls and the antihypertensive effect was sustained. 5. The reduction of plasma volume with hydrochlorothiazide in essential hypertension are similar as changes of total exchangeable sodium. 6. In cases of low salt diet 4gm of daily salt intake, there was similar results as diuretic therapy in exchangeable sodium. 7. In patients who responded well to antihypertensive effect of hydrochlorothiazide or low salt diet (group I), salt loading of 10gm daily showed an increase of total exchangeable sodium and an elevation of blood pressure with statistical significance.

The effect of Roentgen rays on carcinoma of the cervix has long been of great interest to both radiologists and gynecologists. Since most cervical carcinomas are treated by irradiation, any additional knowledge either concerning the radiosensitivity of cervical tumors or their ultimate prognosis would be of value. The vaginal smear is considered to be one of convenient and rapid methods to study the effects of radiation on cervical malignancy. We observed morphologic changes in 297 cytologic preparations obtained from 60 patients who had underwent irradiation for cancer of the cervix. With the morphologic parameters such as cytoplasmic vacuolization, cytoplasmic basophilia, multinucleated giant cell formation, polymorphonuclear leucocytes (PMNL) sticking and postradiation dysplasia, we analyzed the findings in relation to the follow up time interval. The most common effect was the cytoplasmic vacuolization with basophilia of basaloid cells, which were noted in more than 90% of followed patients. The multinucleated giant cell formation and PMNL stickering were noted in 38 cases(63%) and 48 cases(80% ) respectively. The differential diagnosis of postradiation dysplasia from recurrent or persistent carcinoma, reparative atypical cells, and regressing tumor cells was difficult and further study seems to be needed to clarify the more accurate morphologic features and biologic behavior.

PURPOSE: This study focused on in vitro cell differentiation and surface characteristics in a magnesium coated titanium surface implanted on using a plasma ion source. MATERIALS AND METHODS: 40 commercially made pure titanium discs were prepared to produce Ti oxide machined surface (M) and Mg-incorporated Ti oxide machined surface (MM). Surface properties were analyzed using a scanning electron microscopy (SEM). On each surface, alkaline phosphatase (ALP) activity, alizarin red S staining for mineralization of MC3T3-E1 cells, and quantitative analysis of osteoblastic gene expression, were evaluated. Actin ring formation assay and gene expression analysis of TRAP and GAPDH performing RT-PCR were performed to characterize osteoclast differentiation on mouse bone marrow-derived macrophages (BMMs). RESULTS: MM showed similar surface morphology and surface roughness with M, but was slightly smoother after ion implantation at the micron scale. M was more hydrophobic than MM. No significant difference between surfaces on ALP activity at 7 and 14 days were observed. Real-time PCR analyses showed similar levels of mRNA expression of the osteoblast phenotype genes; osteopontin (OPN), osteocalcin (OCN), bone sialoprotein (BSP), and collagen 1 (Col 1) in cell grown on MM at 7, 14 and 21 days. Alizarin red S staining at 21 days showed no significant difference. BMMs differentiation increased in M and MM. Actin ring formation assay and gene expression analysis of TRAP showed osteoclast differentiation to be more active on MM. CONCLUSION: Both M and MM have a good effect on osteoblastic cell differentiation, but MM may speed the bone remodeling process by activating on osteoclast differentiation.

Korean Journal of Dermatology 1986;24(1):127-132
Fibrous papule of the face occurs nearly always as a solitary lesion on the face, especially on the nose. The lesion which appears as a dome shaped papule, is skin colored, pigmented or red, We present herein three cases of fibrous papule of the face, which developed on the ala nasi of 45-year-old man, and 49-year-old woman, and on the nostrile of 25-year-old woman. Histopathologic findings showed dermal angiofibrotic changes in two cases. In one of the two cases, there were atypical cells with large irregular nucleus and a few multinucleated giant cells interspersed in the edematous dermis, and there was distinct perifollicular fibrosis in the other case.

We report herein a case of bowenoid papulosis, which developed on the groin, the shaft of the penis and left parietal area, of scalp in a 31-year-old male. Clinical features present as brown to brown-black papules and verrucous plaques ranging from 2 cm to 12 cm in diameter. Electron microscopic examination of the specimen obtained from our patient fail to reveal viral particles.

10.Effect of H2 - Receptor Antagonists on UVB - Suppressed Contact Hypersensitivity.

Korean Journal of Dermatology 1986;24(6):787-792
The effects of histamine type 2(H2) receptor antagonists, cimetidine and ranitidine, on the induction of contact hypersensitivity and UVB induced suppression of contact hypersensitivity were studied. Our experiment showed that treatment with cimetidine or ranitidine slightly enhanced contact hypersensitivity to DNCB, but the suppression of contact hypersensitivity elicited by UVB were moderatly reversed by ranitidine. These facts suggest that H2-receptor antagonist may be responsible for th blocking histamine induced suppressor factor by acting upon UV-induced suppressor T cell.
