1.Induction and Expression of Chemokines and Their Receptors in Human Mast Cell Line ( HMC - 1 ).
Korean Journal of Immunology 1999;21(4):335-342
The mast cell is an essential effector cell in allergic inflammation through its capacity to respond to IgE dependent activation. Mast cells also participate in the modulation of physiologic processes, but the role of mast cell in these processes is still unclear. Recently, the number of structurally defined chernoattractants for leukocytes has greatly increased, owing to largely to the identification of the chemokine superfamily. In this study we examined the pattern of expression of chemokines and their receptors in HMC-1 after treatment with PMA/A23187 and/or LPS using RT-PCR and ELISA. Messenger RNA of IL-8, the representative CXC chemokine, was induced after PMA/ A23187 treatment. All of the CC chemokines tested, except eotaxin, were induced after PMA/A23187 treatment. CCR1, CXCR2, CXCR3 and CXCR4 were expressed in all test groups regardless of activation. CCR3 was expressed only at 3 hours of activation. CCR2, CCR5 and CXCR1 were not expressed in mast cell line. Production of most of chemokine proteins was not detected in resting state and increased significantly after 3 hours of activation with PMA/A23187. The effect of LPS treatment was negligible. MCP-1 protein was always produced without activation and accurnulated in a time-dependent rnanner. These data suggest that the expression of mRNA and protein of chemokines and chemokine receptors are regulated transcriptionally and translationally. Human mast cell may respond to various stimuli by producing chemokines and their receptors to regulate their function and may act autonomously or through other inflammatory cell that they recruited.

Uterus didelphys with unilateral obstructed hemivagina is indeed a very rare congenital anomaly due to M llerian duct malformation. The most common clinical presentation is pelvic pain and dysmenorrhea shortly after menarche, in associated with the finding of a vaginal or pelvic mass. An accurate and prompt diagnosis is of importance to permit treatment and to assure the future fertility of the patient. The simple and adequate treatment of the condition is incision of the obstructed vaginal septum providing adequate drainage of the retained blood. We report a case of uterus didelphys with obstructed hemivagina with brief review of the literature.

PURPOSE: Hydronephrosis constitutes a great portion of fetal anomalies screened by prenatal sonogram. The present authors made an attempt to access its natural courses through follow up neonatal hydronephrosis diagnosed by prenatal sonogram. METHODS: The study was composed of 23 neonates(36 renal units) who were diagnosed with hydronephrosis through prenatal sonogram screening and confirmed 3-7 days after birth with sonographic evaluation at Kyung Hee University Hospital. The neonates were closely monitored for 12-24 months with renal sonogram, diuretic renogram, intravenous pyelography(IVP) and voiding cystoureterography(VCUG). RESULTS: The underlying diseases were composed of 16 cases(44%) of functional abnormalities, 14 cases(39%) of ureteropelvic junction(UPJ) obstruction, three cases(8%) of vesicoureteral reflux (VUR) and on case each of multicystic dysplastic kidney, UPJ obstruction with ureteral stenosis and ureterovesical junction(UVJ) obstruction with VUR. The degree of hydronephrosis was divided into three classes according to its severity. In 30 renal units with UPJ obstruction and functional abnormalities, 26(87%) showed mild hydronephrosis, while four(13%) were moderate. During the follow up period, six cases(20%) showed natural resolution of hydronephrosis, 15 cases(50%) showed improvement while two cases(7%) were aggravated with improvement only after surgery of the underlying disease. The cases which showed natural resolution were all mild hydronephrosis at diagnosis and the cases which underwent surgery due to continuous aggravation were mild one case and moderate one case. CONCLUSION: Those with cases of mild hydronephrosis show rapid natural improvement. On the other hand, in some cases, follow up monitoring reveal aggravation of the situation, emphasizing the necessity for thorough follow up for a long period of time.
