The mesoblastic nephroma is a rare benign renal tumor that frequently appears as a neonatal abdominal mass. This benign tumor is composed primarily of connective tissue that growth between intact nephrons and often replaces most of the renal parenchyme. Contrast media within the calyceal systems are seen within the tumor representing function by nephrons trapped within the mass. Prognosis after complete excision is excellent.

The authors present a case of macular dystrophy of the cornea which is inherited as a recessive trait. The patient was 43 years old female housewife who had suffered from photophobia, frequent tearing, foreign body sensation and gradually increasing visual dimness since early childhood. Partial penetrating keratoplasty was performed. We had a study of the histopathologic findings for a case of macular dystrophy of the cornea with a brief review of relating literatures.

The authors experienced a case of embryonal rhabdomyosarcoma. The patient was 13 years old bov who had exophthalmos, ocular deviation to upper direction and visual disturbance of his left eye. We excised the exposed mass of tumor by exploration of the orbit and postoperative irradiation with Cobalt-60 was followed. There were no signs of recurrence of the tumor or metastasis to the other part of body until now, 7 months after surgery. We had a study of the histopathologic findings for a case of rhabdomyosarcoma with a brief review of relating literature.

A case of multiple hamartomas of the unilateral chest wall in a four month old infant is presented. There have been a few reports on the CT findings of the chest wall hamartoma in infancy. We describe bone changes of the ribs and mineralization of this rare tumor on the CT scan, and the locations of two separate masses.

This study aimed 1) at determining the seasonal pattern of the first onset and 2) at examining different demographic and clinical factors by the seasonality of first onset, for shizophrenia, mood disorder and subtypes of each diagnosis. Finally, the 52 subjects with paranoid schizophrenia were selected from all patients who fulfilled DSM-IV criteria far schizophrenia who had been admitted to the National Seoul Mental Hospital from March 1994 to February 1995. And the 44 subjects with bipolar I disorder were selected from all patients who fulfilled DSM-IV criteria for mood disorder who had been admitted to the hospital from March 1994 to February 1996. This study was done by reviewing the hospital records about season of the first outset, demographic factors(sex, age, occupation, educated period, religion, marital status, residence and socioeconomic status) and clinical factors(age at the first onset, duration of illness, family history, length of admission, frequency of admission and treatment result). The seasonal pattern of the first onset and the different demographic and clinical factors by the season of the first onset in paranoid shizophrenia and I disorder were analyzed. The results were as follows: 1) There was no significant seasonal variation of the first onset for paranoid schizophrenia. 2) There was a significant seasonal variation of the first onset with a maximum in spring for bipolar I disorder. 3) There was no significant seasonal variation of the first onset in case of bipolar I disorder that began with the manic episode. 4) There was nonsignificant seasonal tendency to peak in spring/summer in the case of the first manic episode for bipolar I disorder. 5) There were no significant differences in demographic and clinical factors by the season of the first onset for paranoid schizophrenia and bipolar I disorder.

This study was designed to investigate the effect of diazepam on the spontaneous contraction and oxytocin induced contraction of the isolated rat uterus. Female rat (Sprague-Dawley) pretreated with oophorectomy and 4 days administration of estrogen. Weighing about 200 g, was sacrificed by cervical dislocation, and the uteruses were isolated. A longitudinal muscle strip was placed in temperature controlled (37℃) muscle chamber containing Locke's solution and myographied isometrically. Diazepam inhibited the spontaneous contraction and oxytocin induced contraction of the isolated rat uterus in a concentration-dependent manner. GABA, muscimol, a GABA A receptor agonist, bicuculline, a competitive GABA A receptor antagonist, picrotoxin, a non competitive GABA A receptor antagonist, baclofen, a GABA B receptor agonist, and delta-aminovaleric acid, a GABA B receptor antagonist, did not affect on the spontaneous and oxytocin induced contraction of the isolated rat uterus. The inhibitory actions of diazepam on the spontaneous and oxytocin induced contraction were not affected by all the GABA receptor agonists and antagonists, but exceptionally potentiated by bicuculline. This potentiation-effect by bicuculline was not antagonized by muscumol. In normal calcium PSS, addition of calcium restored the spontaneous contraction preinhibited by diazepam and recovered the contractile of oxtrocin preinhibited by diazepam. A23187, a calcium inophore, enhanced the restoration of both the spontaneous and oxytocin induced contraction by addition of calcium. In calcium-free PSS, diazepam suppressed the restoration of spontaneous motility by addition of calcium but allowed the recovery of spontaneous motility to a considerable extent. Diazepam could not inhibit some development of contractility by oxytocin in calcium-free PSS, but inhibited the increase in contractility by subsequent addition of calcium. These results suggest that the inhibitory action of diazepam on the rat uterine motility does not depend on or related to GABA receptors and that diazepam inhibits the extracellular calcium influx to suppress the spontaneous and oxytocin induced contractilities.
