Prenatally diagnosed neuroblastomas have been reported in increasing numbers over the past several years. The vast majority are in favorable stages of the disease (stage I, II, IV-S). The authors experienced one case of stage IV-S neuroblastoma of the adrenal gland with liver metastasis, which regressed spontaneously after removal by adrenalectomy. This patient was noticed to have an abdominal mass at prenatal ultrasonography performed at 36weeks of gestation. This tumor was a neuroblastoma of the left adrenal gland with multiple liver metastases. Left adrenalectomy and liver biopsy were performed at 3 months of age. Thirty-eight months after surgery, an MRI demonstrated that the hepatic metastatic lesions had completely regressed without chemotherapy or radiation.

Eighteen unselected, consecutive cases of benign prostatic hyperplasia, 18 unselected cases of other urological conditions in same age group have been studied with particular reference to the size of the glans penis. Of 18 cases of benign prostatic hyperplasia,17 had prominently well-developed and large glans penis-"prostate-glans"-, while all cases of carcinoma of the prostate and most of control cases had small or ordinary-sized glans. There was no close correlation between the size of the glans and grade of prostatic enlargement. From this study, it might be concluded that prominently large glans is a possible sign of benign prostatic hyperplasia and those who have very large glans in association with urinary obstruction in elderly males are likely to have benign prostatic hyperplasia.

BACKGROUND: N-acetylcysteine(ACE) is used both orally and intravenously in a variety of experimental pathologies resembling human disease states which exhibit endothelial toxicity as a result of oxidative stress, including acute pulmonary oxygen toxicity, septicemia and endotoxin shock. Despite these observations in vivo, it is not certain how this thiol drug produces its protective effects. ACE is a cysteine derivative which is able to directly react with oxygen radicals and may also act as a cysteine and glutathione(GSH) precursor following deacetylation. In this paper, we tried to know whether the therapeutic doses of ACE can modify the inflammatory function of the neutrophils and can increase the glutathione level of plasma in chronic obstructive pulmonary disease(COPD) patients. In addition, the effect of ACE to the purified neutrophil in terms of superoxide release and glutathione synthesis were observed. METHOD: Firstly, we gave 600mg of ACE for seven days and compare the release of superoxide, luminol-enhanced chemiluminescence from the neutrophils, neutrophil chemotaxis, and plasma GSH levels before and after ACE treatment in COPD patients. Secondly, we observed the dose dependent effect of ACE to the purified neutrophil's superoxide release and GSH levels in vitro. RESULTS: 1) Usual oral therapeutic doses(600mg per day) of ACE for seven days did affect neither on the neutrophils superoxide release, chemiluminescence, chemotaxis, nor on the plasma GSH concentration in the COPD patients. 2) ACE decreases the purified neutrophil's superoxide release and increase the GSH production in dose dependent fashion in vitro. CONCLUSION: Despite the fact that oral ACE treatment did not affect on the neutrophil's inflammatory function and plasma GSH concentration in COPD patients in usual therapeutic doses, it decreases the superoxide release and increases the GSH production from the isolated neutrophils in high molar concentrations. These findings suggest that to obtain an antioxidative effects of ACE, it might be needed to increase the daily dosage of ACE or therapeutic duration or change the route of adminisration in COPD patients.

Acardiac twinning affects 1 in 100 monozygotic twin pregnancies and 1 in 35,000 pregnancies overall. This condition is characterized by the absence or rudimentary development of fetal heart, and associated with various anomaly. The presence of an acardiac twin requires the normal (or "pump") twin to provide circulation for itself, as well as the acardiac sibling. The acardiac malformations are uniformly fatal in the affected twin, and mortality in the co-twin is as high as 55%. The principal perinatal problems associated with acardiac twinning are pump-twin congestive heart failure, maternal hydramnios, and preterm delivery. We recently experienced a case of acardius anceps associated with a normal male infant, so present with a brief review of the literature.

Estrogenic hormone in various doses and durations was administered to adult male white rats to study the hormonal effect on the prostatic gland. In this study 48 rats. weighing approximately 250 gm. were divided into 8 groups of six rats. Group 1: Control for 2 weeks experiment Group 2: Control for 4 weeks experiment Group 3. Administration of estradiol 0.5 mg., 7 doses Group 4: Administration of estradiol 0.5 mg., 14 doses Group 5. Administration of estradiol 0. 25 mg., 7 doses Group 6: Administration of estradiol 0. 25 mg., 14 doses Group 7: Administration of estradiol 0. 125 mg., 7 doses Group 8: Administration of estradiol 0. 125 mg., 14 doses Estradiol was administered every other Day as scheduled. One day after the final injection, the animals were sacrificed. Body weight and weight of the prostatic gland, both the ventral and the dorsal lobes, were obtained. The effect of estradiol in various doses on the prostatic size was observed to be almost the same throughout the experimental groups. But estradiol administered for longer periods has slightly more effect than when administered for shorter periods. The effect of estrogen administered to the rats with intact gonads did not antagonize or neutralize the endogenous testicular androgen, but did suppress the release of pituitary gonadotrophin, resulting in less production of testicular androgen. A large dosage of estrogen does not necessarily cause a marked reduction in the prostatic weight.

Androgenic and estrogenic hormones were administered to adult male white rats with intact gonads and adult male white castrate rats to study their effects on citric acid concentration of the prostate gland. In this study 30 male rats, 14 to 16 weeks of age, weighing approximately 250 to 300 gm., were divided into 5 groups of six rats: Group 1: Control Group 2: Administration of testosterone propionate 0.5 mg., 7 doses Group 3: Administration of estradiol 0.2 mg., 7 doses Group 4: Castration and administration of testosterone propionate 0.5 mg., 7 doses Group 5: Castration and administration of both testosterone propionate 0.5 mg. and estradiol 0.2 mg., 7 doses each. One day after the final injection with sex hormones, the animals were sacrificed and the prostatic citrate was determined using the Kim-Tesar modification of the Taylor's method. Estrogen administration to the male rats with intact gonads caused an increase in the prostatic citrate concentration. Testosterone propionate administration after castration returned the citrate concentration to normal, but estradiol administration along with testosterone propionate after castration caused a rise in the prostatic concentration of citric acid. Hypophysectomized white rats purchased from the Hormone Assay Laboratory were castrated and were administered androgen and estrogen to study their effects on the prostatic concentration of citric acid, 36 rats were divided into 6 groups of six rats: Group 1: Control (no hypophysectomy) Group 2: Hypophysectomy and castration Group 3: Hypophysectomy, castration and administration of testosterone propionate 0.5 mg., 7 doses Group 4: Hypophysectomy, castration and administration of both testosterone propionate 0.5 mg, and estradiol 0.5 mg., 7 doses each Group 5: Hypophysectomy castration and administration of both testosterone propionate 0.5 mg. and estradiol 0.25 mg., 7 doses each Group 6: Hypophysectomy, castration and administration of both testosterone propionate 0.5 mg. and estradiol 0.125 mg., 7 doses each. Hypophysectomy and castration caused a marked increase in the prostatic concentration of citric acid. When testosterone propionate was administered to hypophysectomized castrate, the ciric acid value returned to normal. Administration of estradiol along with testosterone propionate to hypophysectomized castrate caused changes in the prostatic citrate concentration according to the dosage of estradiol administered, the more the dosage, the more the concentration of the prostatic citrate. Concentration of the prostatic citrate can not be taken as an index of androgenic activity.
