This review aims to introduce the basic neurobiological aspects of dream. There have been long debates on whether the neurobiology of rapid eye movement (REM) sleep is identical to that of dream. However, many theories on dream are based on the findings of REM sleep. Bizarre cognition and intense emotion in dream have been suggested to derive from physiological (e.g. desynchronized gamma oscillation and postsynaptic inhibition), chemical (e.g. decreased noradrenalin and serotonin, increased acetylcholine and modulation of dopamine), anatomical (e.g. deactivation of dorsolateral prefrontal cortex and activation of limbic and paralimbic areas) change in REM sleep. In addition, dream has been suggested to play its neurobiological roles. Processing of negative emotion may be one of the functions of dream. Dream is also supposed to consolidate memory, especially semantic memory. Despite a number of hypotheses and debates, the neurobiological mechanism of dream generation has not been concluded.

Experimental hydronephrosis was induced in rabbit by ureteral ligation, then deligation followed after certain experimental period as designed. Histopathological changes of the kidney and restoration of hydronephrosis were studied and the following results were obtained: 1. Ligation of the ureter for 3 days produced mild to moderate degrees of tubular dilatation. irregular proliferation and dilatation of small arterioles. Deligation initiates regeneration of the tubules at 1 week and almost normal histology returns by 3 weeks. 2. Ligation of the ureter for 5,7 and 14 days causes marked tubular dilatation, atrophy of the .cortex, and partial obliteration of the glomerulus. By 3 weeks after deligation, the tubules seem to partially regenerate but no significant histological changes were observed. 3. Ligation of the ureter for 21 to 60 days causes formation of scar, marked obliteration of the glomerulus and compensatory hypertrophy of the remaining glomerulus. No morphological restoration was observed by 3 weeks after deligation. 4. It seems that histological restoration starts at periglomerular tubules located closer to the cortex toward the medulla.

A clinical study was made on 117 cases of benign prostatic hyperplasia admitted to the Department of Urology, Chungnam University Hospital during the period from January 1974 to August 1982. The results were summarized as follows: 1. Common symptoms were dysuria (82.1%) and urinary retention (41.0%). 2. Gross or microscopic hematuria was noticed in 48 cases (41.0%). 3. The degree of prostatic enlargement by rectal palpation was not related to the severity of symptoms. 4. Pulmonary disease (19.5%) and cardiac disease (12.8%) were frequently associated with B.P.H. 5. Treatment consisted of suprapubic of retropubic prostatectomy in 94 cases, TUR in 7 cases and cystostomy in 10 cases. 6. Postoperative complications were urinary incontinence (34%), wound problem (9.7%), delayed bleeding (8.7%), and urinary tract infection (4.8%). 7. Mean weight of removed prostatic tissue was 31.3gm.
