The present study was aimed at investigating the effect of cyclosporine A (CsA) on the renal renin-angiotensin systems. In rats chronically treated with CsA, the intrarenal expression of various genes of the renin-angiotensin system was assessed by Northern blot analysis. Along with the increases in plasma and renal renin activities, chronic CsA-treatment differentially affected the renal expression of renin-angiotensin system. The treatment with CsA for one week did not significantly alter the expression of either type 1 angiotensin II receptor (AT1A) or angiotensinogen gene, but increased the renin mRNA level. The three-week-treatment caused increases in the expression not only of renin but also of AT1A and angiotensinogen genes. Supplementation with L-arginine kept the expression of renin mRNA normal in the one-week-treated, but failed to prevent the alterations of the gene expression in the three-week-treated. Feedback control among components of the renin-angiotensin system also influences angiotesinogen. In the liver, the expression of angiotensinogen mRNA was decreased by the CsA-treatment for either one- or three-weeks. In conclusion, chronic CsA-treatment is associated with a differential expression of various genes for the renin-angiotensin system. L-Arginine may be effective in maintaining the normality of renin-angiotensin system only during early period after beginning the use of CsA.

The present study was primarily carried out to characterize the properties of the spinomesencephalic tract (SMT) neurons that project from the upper cervical spinal segments to the midbrain. It was also investigated whether these neurons received convergent afferent inputs from other sources in addition to cervical inputs. Extracellular single unit recordings were made from neurons antidromically activated by stimulation of midbrain. Recording sites were located in lamina IapprxVIII of C1apprxC3 segments of spinal cord. Receptive field (RF) and response properties to mechanical stimulation were studied in 71 SMT neurons. Response profiles were classified into six groups: complex (Comp, n = 9), wide dynamic range (WDR, n = 16), low threshold (LT, n = 5), high threshold (HT, n = 6), deep/tap (Deep, n = 10), and nonresponsive (NR, n = 25). Distributions of stimulation and recording sites were not significantly different between SMT groups classified upon their locations and/or response profiles. Mean conduction velocity of SMT neurons was 16.7 +/- 1.28 m/sec. Conduction velocities of SMTs recorded in superficial dorsal horn (SDH, n = 15) were significantly slower than those of SMTs recorded in deep dorsal horn (DDH, n = 18), lateral reticulated area (LRA, n = 21), and intermediate zone and ventral horn (IZ/HV n = 15). Somatic RFs for SMTs in LRA and IZ/VH were significantly larger than those in SDH and DDH. Five SMT units (4 Comps and 1 HT) had inhibitory somatic RFs. About half (25/46) of SMT units have their RFs over trigeminal dermatome. Excitabilities of 5/12 cells and 9/13 cells were modulated by stimulation of ipsilateral phrenic nerve and vagus nerve, respectively. These results suggest that upper cervical SMT neurons are heterogenous in their function by showing a wide range of variety in location within the spinal gray matter, in response profile, and in convergent afferent input.

As times go by, the objects and subjects of researches have changed. Forensic medicine and science can not be escaped. To overview the international changes and trend of forensic medicine and science, we gathered abstracts of 3,354 articles from 5 outstanding international journals, those are (1) Forensic Science International, (2) Journal of Forensic Science, (3) American Journal of Forensic Medicine and Pathology, (4) Medicine, Science and the Law, (5) International Journal of Legal Medicine. There were 1,226 articles (36.6%) on forensic pathology, followed by forensic genetics (902 articles, 26.9%), toxicology (549 articles, 16.4%), forensic sciences (445 articles, 13.3%) and medical law & criminal psychology (232 articles, 6.9%). Corresponding authors from 4 countries (USA, Great Britain, Germany and Japan) took more than half of total corresponding authors. And there were 27 articles (0.8%) from Korea. This article will introduce us an overview of international trend of forensic researches.

Leprosy is a multisystemic infectious disease showing various cutaneous manifestations by the reaction between Mycobacterium leprae (M. leprae) and host immunity. We de-scribe a 20-year-old woman with clinical multiple papulonecrotic skin eruptions resembling papulonecrotic tuberculid (PNT) and pityriasis lichenoides et varioliformis acuta (PLEVA). This kind of skin eruption is a new manifestation which has not been reported so far in lepromatous leprosy (LL).

Transitional cell carcinoma of the bladder in children is the rarest tumor. Less than 20 cases in children have been reported in the literatures since the first report by Campbell in 1951. We report a case of papillary transitional cell carcinoma of the bladder in a 4-year-old boy and literatures were reviewed.

A 34-year-old man visited our hospital with alopecia areata on the occipital scalp, which began to develop two months prior to his visit. He was sensitized with 0.2% diphenylcyclopropenone(DPCP) in acetone that was applied to the inner side of his right arm. Two weeks after sensitization, we applied DPCP on his bald lesion once weekly for skin challenge. Following the third application of DPCP, polycyclic erythematous target-like lesions developed around the sensitized area. A clinical diagnosis of erythema multiforme was made. Histologically, the target-like lesion showed few eosinophilic dyskeratosis, exocytosis, and hydropic de-generation of basal layer in the epidermis, and mononuclear infiltration around superficial blood vessels in the dermis. We report herein a rare case of erythema multiforme following topical application of DPCP in the treatment of alopecia areata. This complication must be noted because of the wide-spread and frequent use of DPCP in dermatotherapeutic fields.

The operative technic for the correction of hydronephrosis due to obstruction at ureteropelvic junction has been discussed. There are two different types of technics in pyeloplasty ; 1st. nondismembered pyeloplasty molds and restructures the obstructed ureteropelvic junction without completely dismembering it and 2nd. dismembered pyeloplasty interrupts the continuity of the transport system of the obstructed ureteropelvic junction. Since Andereon-Hynes reported the technics which belongs to dismembered pyeloplasty for retrocaval ureter in 1949, many articles with satisfactory result have been published. We report Anderson-Hynes pyeloplasty for hydronephrosis secondary to obstruction of the ureteropelvic Junction in 7 cases. Advantages of Anderson-Hynes pyeloplasty are as follows. 1. Complete excision of the obstructive segment. 2. Reduction of the dead space. 3. Excision of a good part of the sick pelvis. 4. Activation of latent pacemaker P cells.
