Apraclonidine is a potent alpha-adrenergic agonist that, like clonidine, is relatively selective for alpha-2 receptors. Apraclonidine has been shown to lower intraocular pressure by diminishing aqueous humor formation. The purpose of this study is to know the morphological changes in the ciliary epithelium by apraclonidine against aqueous formation. In group I, two drops of 1% apraclonidine hydrochloride were instilled on the right eye of the pigmented rabbits and the eyes were enucleated on 1,2.6 and 24 hours after instillation to find out the duration of action of the drug and the tissue response. In group II, one drop was instilled twice daily for seven days on the right eye and the eyes were enucleated on 1, 2 and 5 days after cessation of the instillation observing the cumulative effect of the drug and the tissue response. These eyes were studied with electron mIcroscopIc examiation. As a result, widening of cell membranes(basal infoldings) of the non-pigmented epithelium(NPE) were observed. This change was recovered with time, and seems to be the principal morphological changes of apraclonidine against aqueous formation in the ciliary body. In group II, the cellular changes were minimal except for well developed rough endoplasmic reticulum representing resumed secretary function of the cell.

Incarceration of the gravid uterus is a rare but serious complication of pregnancy. Reported is the case of a gravid 2, para 0, abortus 1 with known uterine subserosal myoma(5.3 x5.5cm sized) 26-year-old woman presented with acute dysuria and urinary retention. The patient was 14 weeks and 3 days pregnant and presented several week history of urinary frequency and sensation of incomplete bladder emptying. Examination revealed a retroflexed uterus with cervical opening pointing toward the anterior abdominal wall. An ultrasound revealed a thin, elongated maternal bladder and a uterus incarcerated between the sacral promontary and the pubis. The incarceration was successfully reduced by tenaculum traction of the cervical posterior lip without surgical intervention and had a normal infant of appropriate weight at term.

OBJECTIVES: This study aimed to examine the point prevalence of anxiety, depression and the associated risk factors in hospitalized patients with cancer. METHODS: A total of 114 patients with cancer who admitted to the Cancer Center in St. Mary's Hospital were enrolled for a day. The patients were asked to complete Hospital Anxiety and Depression Scale(HADS). Sociodemographic and cancer related clinical variables were also evaluated. RESULTS: The point prevalence of anxiety and depression was 10.5% and 34.2%, respectively, as assessed with HADS. Logistic regression models revealed that distant metastasis was significantly associated with anxiety in patients with cancer and previous chemotherapy and Low socioeconomic status were significantly associated with depression. CONCLUSIONS: Our results indicate that more than one third of patients with cancer suffer from either anxiety or depression. In addition, previous chemotherapy as well as low socioeconomic status and distant metastasis were associated risk factors of anxiety and depression, respectively. These findings suggest the need for screening and systematized psychosocial intervention for psychological distress in hospitalized patients with cancer.

Pregnancy-induced hypertension(PIH) is one of the major causes of maternal, fetal and neonatal morbidity and mortality. Although many causes are encountered, etiology of PIH is still unknown. A molecular variant of angiotensinogen, M235T, reported to be linked with essential hypertension and PIH. This study was to evaluate the molecular variation of angiotensinogen in Korean pregnancy-induced hypertension. Our results did not provide any definite relation with the molecular variant of angiotensinase, M235T, and Korean PIH.

Myeloid body formation is an ultrastructural feature of gentamicin induced nephrotoxicity in human being and experimental animals. The origin of the myeloid body is not satisfactorily understood and morphological verification of the developing process of this structure is not fully accomplished. We injected 100 mg/kg/12 hour of gentamicin in 20 Spraque-Dawley rats and examined the ultrastructural feature of the proximal convoluted tubular cells of the kidney every 30 minutes in the first 4 hours, and in 5 hours, 6 hours, 12 hours, 24 hours and 48 hours after injection of gentamicin, with a TEM and a SEM. Myeloid bodies were noted as concentric layers of membranous structures of degenerated endoplasmic reticulum and mitochondria in the lysosome. The number and size of the myeloid body containing lysosomes were increased with time. We can deduce from this observation that injured cell organelles by diffusible gentamicin within the cells are autophagocytosed by lysosomes which were also injured by the drug from pinocytotic vesicles, and incompletely digested organellar remnants are retained in the lysosomes as myeloid bodies. So we think that the myeloid body formation is a result of an exaggerated and a pathologic autophagocytic process due to cell injury induced by gentamicin.
